So what I want to share today is the most "introductory" Weilai brand small electric car, its three screens, the latest? Ota? Version and the actual experience of our commonly used maps, air conditioners and audio functions.
Mine? NOMI？ No screen
The birth of science and technology itself is to solve the problem of efficiency on the premise of ensuring safety. Therefore, the topic that can't be avoided when discussing the car machine of smart car is convenience, efficiency and safety.
In the long run, the voice with the lowest interaction cost will become the mainstream. However, Wei Lai obviously has more ideas in voice interaction. NOMI？ Judging from the anthropomorphic setting, Weilai not only affirmed the priority position of voice in car-machine interaction, but also made emotion engine more interesting, using the voice system from Iflytek? NOMI？ Is the first step in their practice.
If there is a choice? NOMI？ Dude? In that case, this "little head" must be the most eye-catching existence in the car. My car is a standard NOMI? Aura? Although it doesn't cost much, their basic functions are the same. But less? NOMI？ This "little man's head" lacks a little anthropomorphic interaction, which I expected, but the voice feedback in the car became more blunt, which was unexpected.
From the point of view of convenience, NOMI? It has a "one-word touch" function, and can speak voice commands directly after waking up. At present, the main application scenarios are entertainment information and temperature control, and they are also excellent in the face of "I'm a little hot" and other scenarios that need semantic extension and understanding. Besides? NOMI？ In the aspect of sound source localization, it can also accurately identify which seat person gave the instruction.
From the point of view of efficiency, the advantage of doing this is that it can save trouble, and many things that should be operated by hand can be solved by voice. From making sounds to? NOMI？ It also shows the delay and smooth reaction time of executing voice instructions.
But? NOMI？ There are certain requirements for the use environment, and you will encounter voice interference from non-awakens when you wake up. Every time you wake up? NOMI？ It will be accompanied by the "home screen" of the entire central control screen. This phenomenon will not only pause music playing, but also directly affect the use effect of the most important navigation map in the driving scene. This experience is not good enough.
To sum up, although? NOMI？ There is indeed a lot to praise, but wake up? NOMI？ The speech will be interfered by other audio sources, and there will be a phenomenon of "dominating the screen", which is a bad experience when using Weilai vehicle. The specific reasons can be seen below.
Instrument panel with temperature
Based on what? QNX？ System design? 8.8? The advantages of Inch dashboard are naturally small kernel, fast running speed, and screen resolution? 1400* 1600, what is the highest brightness? 1000? Nit, which can see the screen clearly even in direct sunlight, is the "above the fold" for drivers to obtain driving information, and its stability and real-time performance are self-evident.
In addition, as the screen with the lowest cost for drivers to obtain driving information, the dashboard displays more effective information in a limited space, which is a "selection" process for car companies.
The upper part of the screen mainly shows the vehicle speed, motor power and some warning lights. What I want to mention here is my favorite "real-time motor power display", which shows the speed on the left and the power on the right with icons of the same size. I believe that in addition to the symmetry in design, Weilai thinks that the weight ratio of the two is the same in design.
Because this kind of "real-time motor power display" can not only let the driver know intuitively whether the current vehicle is in the state of kinetic energy recovery or output power, but also know the current output power, which is very similar to the real-time speed displayed by the tachometer on the traditional tanker.
Although many people around me think this function is "chicken ribs", this is what I call "choice". Because for me, this function has helped me find some sense of participation in driving.
In addition to the middle position, Wei Lai left the core screen space position to the assisted driving visualization. The system displays three lanes by default, and the surrounding traffic participants can display them intuitively. However, due to the perception of millimeter-wave radar, this visualization system algorithm will uniformly judge the "two-wheeled vehicle" coming from behind as "four-wheeled vehicle", but this is not a big problem.
Besides, in? NOP？ What is the interface in the pilot assisted state? UI？ Different pictures will be displayed over time, such as sunrise and sunset. What if? Naomi? It is the "emotion engine" of communication between people and vehicles, so this "small mind" is to highlight the "human temperature" of Weilai enterprise.
Finally, look at the bottom right of the screen. In addition to the regular display of driving gear and mode, cruising range information will also be displayed. But does it still work? NEDC？ Computational logic, as an information display, deviates from the needs of the actual automobile scene. I insist that the user's battery life anxiety is more due to battery life accuracy than how much battery life is left. Just like consumers in the purchase decision of pure electric vehicles, the convenience of "energy supplement system" is above the "absolute cruising range" factor.
Experience-oriented central control panel
What about the one provided by Desai Siwei? 1 1.3? Inch full LCD central control panel, full bonding process is not easy to reflect light, using Corning Gorilla's glass panel, resolution is? 1600* 1400? , supporting multi-touch. The luxurious hardware configuration and manufacturing technology also reflect Weilai's consistent corporate style of "spending money to solve things and never being soft".
Because of Weilai's own understanding and insistence on "user experience" and "security", they made this Android car semi-enclosed.
In terms of experience, Wei Lai thinks that most of them? App？ Not suitable for driving scenes, and? UI？ Can not be integrated into the design style of the current car machine. If it is forced entry, it is not a good experience.
As for security, Wei Lai explained that we have done isolation and prevention, and the security problem can be overcome, but there is no absolute security in this world.
And if we say the weight of the two, what is Wei Lai's answer? 95%? Because of experience, 5%? Because of "safety".
But the result of this is that applied ecology is only? QQ？ Music, Iqiyi, Himalaya. Frankly speaking, Weilai and users know that there are still many shortcomings in the current automobile system.
Of course, you can call this "timid" or "stubborn". Everyone's scene is different, which determines the basis of how to judge, but what I want to say is that Wei Lai is the one who knows best what Wei Lai does.
As far as this "semi-closed system" is concerned, first of all, Weilai must have spent a lot of time and really put the home page? UI？ The design is suitable for various scenarios, including? QQ？ Music and iqiyi are opening up these third parties? App？ Backstage? UI？ The design is not in contradiction with the whole automobile machine.
This car is really rich in functions, and there are many interactive ways, including physical buttons, touch screen, steering wheel, blind gestures and voice interaction, but this is "good and bad".
The good news is:
First, the functional items are rich. Enter the settings page, no matter what function you want or not, you can find it on this page and set it according to your own preferences, and remember the habits of each user through authorized accounts.
The second is to distinguish between priorities. On the home page, the frequently used music and map function settings in the driving scene are in very conspicuous places, which is very convenient to operate.
Third, the reserved physical button is "just needed". In addition to steering wheel assisted driving and audio control keys, the control buttons below the central control? Home? The key is the core, close to the driver's location layout, so that no matter which page the current car is on, you can switch back to the map home page conveniently and quickly.
The bad news is:
First, there are many interactive pages. The operating logic of the system is similar to that of the mobile phone Android system, which is mainly composed of the home page? +? Function list page? +? The operation page has been completed. But according to this logic, the three-level page can reach the operation page of the terminal. Such a variety of interactive processes is not conducive to convenience and efficiency.
Second, almost every page is "hegemony". First of all, the "hegemony screen" will inevitably slow down the application opening time, and secondly, it will affect the use of maps in driving scenes.
Third, the shortcut menu is not fast. Wei Lai obviously noticed the troubles caused by various pages, so she supported her finger to slide from left to right on the homepage and pulled out a support? 12? Project function custom adjustment quick operation page. Coupled with the low recognition rate of sliding from left to right, for drivers, the cost of manually sliding the screen is much higher than clicking on the screen.
Although functional richness is one of the criteria to measure the Excellence of automobile engines, it will only make the efficiency low if it is separated from good interaction. At this point, I insist that the future vehicle-machine interaction logic must develop in the direction of fewer interaction steps and simpler interaction logic.
2.8.0? Version update
Shall we look at this time again? NIO？ OS？ 2.8.0? The main content of the update, "automatic locking when leaving the car", has finally appeared, forming an experience closed loop with the previous "automatic unlocking when approaching the car". The principle of this technology is to judge the relative position relationship between the user and the vehicle through the continuous communication between the antenna and the key in the car. After nearly a year, the memory of the co-pilot seat and the function of convenient entry and exit, the "queen" on Wei Laike's car can finally get the same treatment as the "driver".
What I want to say is "automatic locking when you leave the car". Weilai didn't intend to make a Bluetooth key for her mobile phone from the beginning. Originally developed? NFC？ Key, more consideration is also aimed at? b？ Terminal market, such as one-click boot, worry-free service. It's just that the user's voice for mobile phone keys is too high, so Weilai launched Weilai application on the user side. NFC？ Keys, but? NFC？ You also need to take out your mobile phone to "follow the fate". This experience is not enough.
This is like the concept of "auto-lock when leaving the car" is good, but as an intelligent electric car, it has not got rid of the "auto-lock when leaving the car" of the physical key. It's like buying a smart phone, but it doesn't support caller ID, so you still have to bring one. BB？ A machine that checks incoming calls. ? Therefore, I always think that "Bluetooth key of mobile phone" is the "final solution" in experience.
There is also the ease of driving in and out of the linkage steering wheel. At present, with "opening the door" as the trigger function, the feeling in the scene of getting off is not very strong, and the experience in the scene of getting on the bus will be better. After all, in the scene of getting off, no one will wait for the steering wheel to move.
Actually, I had my doubts before. Why not "hold on"? p？ File "as a condition to trigger easy access. Until I dug up the official explanation of Weilai, they thought that many times users were still hanging up after arriving at their destination? p？ Documents, don't leave the car at once. I want to finish listening to a song or a program. Such a scene of solitude and immersion is precious in the world of adults, and they don't want to disturb it. At this point, I was completely convinced by Wei Lai.
As for the charging port lighting and? Nio？ Radio, I have hardly experienced it, so I don't comment. And should appear in? 2.8.0? According to Weilai, the version of the "call function" is because users of Weilai "Pilot Group" gave a lot of feedback during the experience stage, and in order to provide users with a better experience, the online plan was postponed. In this regard, I think it is a question worth pondering whether it is to "pursue a better experience" or "slow progress in software development".
Let's talk about the "unique" Weilai disconnection problem. Among the three elements of normal network connection, if the operator base station and the service provider are normal, then it is only possible that there is a communication problem between the vehicle and the operator base station.
Because our car is moving, it is called "roaming" in the world of network connection, so moving in different base station coverage areas requires "on-board baseband" and constantly switching to receive base station signals. Then the problem of network disconnection is to leave this base station area and there is no signal to connect to the next base station in time.
Then the cause of the problem has been found. Let's look at "who will carry the pot". First of all, the hardware of Weilai's communication network module, although the technology was four years ago, is redundant and adopted? Intel? Baseband, so even today, it is an advanced mass production solution. It turns out that there is nothing wrong with the hardware, which is a matter for the software department. I hope this time? Ota? It's the last edition, and it has something to do with the disconnection.
This update? NOP？ Auto-restart time of car following is adjusted to? 60? Seconds will make assisted driving more persistent in congested road conditions. But there is no adjustment? NP？ If the start-up time in the state is still limited by the inability to identify pedestrians and animals that suddenly appear and take braking measures, it seems that the progress of research and development is slow. Frankly speaking, users will be tired of listening to the rhetoric of "strategic conservatism".
It is worth mentioning that the automatic locking of the car, the convenient entry and exit of the co-driver, and the memory are not too difficult at the technical level. Why did you come so late? Actually, look back at the previous edition? 2.7.0? Ota? After upgrading, we can find that Wei Lai is right in strategy? NOP？ Push has a higher priority.
Of course, if you think this only shows that Weilai pays more attention to assisted driving iteration, it may be a bit "one-sided". Because what's more interesting is that Wei Lai is here? 2020? Year? 10? Month? 10? Push the tape to the user from day one? NOP？ Pilot-assisted 2.7.0? Version, and this time only from Weilai to cancel the lifetime free power exchange time? 2? God, as for coincidence or not, only Wei himself will know.
Map, sound, air conditioning experience
map
Weilai car machine uses Baidu map, and the interactive mode can be through voice and touch, which is more convenient to use. The ways to obtain navigation information are voice broadcast, dashboard and central control screen. It's worth mentioning, from Awakening? NOMI？ When the navigation was successful, when did I measure it? 16? Seconds or so, this is actually very close to the experience of mobile phones.
The topic of who is better, Baidu map or Gaode map, is not what I want to talk about today.
What I want to say is that this system is based on Baidu map car version? The SDK redeveloped by Weilai's software team includes map testing, problem discovery and reappearance. To put it bluntly, this map system integrates many elements of Weilai.
As an electric vehicle, the map system bears the brunt and needs to integrate the resource information of charging piles. As a Weilai brand electric vehicle, it is more necessary for "pile-free users" to integrate the resource information of power stations.
If you study the car map carefully, you will find that Weilai even integrates energy resources? Nio？ House? Information. This also shows that Weilai hopes to penetrate more into users' life scenes through the energy supplement system and offline activities, enhance brand reputation and expand the "intention" of word-of-mouth publicity.
But then again, the elements of the brand itself are important, but the essence of the map is to meet the needs of navigation. This set of Baidu maps, in practical application, not only has some minor flaws such as the path planning is not smart enough and the map screen is not followed manually, but also has a "map display delay" that needs urgent repair? BUG. Frankly speaking, because of this, I often miss many intersections, which eventually leads to the use of mobile navigation to ease the embarrassment.
air conditioning equipment
Because of getting rid of the traditional internal combustion engine and adopting the new energy vehicle driven by electricity, the frequency of air conditioning function in the whole vehicle is further improved, and the air conditioning regulator is inconvenient, which greatly affects the overall car experience.
The way Weilai turns on the air conditioner is also through voice+touch. It is more convenient to adjust the air conditioner by voice, and basically all operations can be easily completed.
But touching the air conditioner, this experience is more general.
The first reason is that you can't find the option to directly adjust the air conditioner on the home page, and you have to do an "unnecessary" operation to enter the secondary page of air conditioner adjustment.
The second reason is that after coming to the secondary page, the operating area is too small and the eye cost is relatively high, whether it is to touch or slide to adjust the temperature and air volume.
As for why the voice is easy to use, but also touch operation? Echoing what I said at the beginning, because I can't keep the others in the car silent until I wake up the bully first? Nomi ",after adjusting the air conditioning temperature, start the chat mode.
It is worth mentioning that this air conditioning system has the function of "automatic defogging". The working principle is that it will automatically defog according to the temperature difference between inside and outside the car. Although the phenomenon of "oolong" occasionally appears in practical application scenarios, the overall performance is not bad. But for a function without interaction cost, who will refuse it unless it is extremely bad?
audio frequency
Weilai has more interactive ways in the audio field. Steering wheel button? +? Central control button +? Touch? +? Voice can control the audio system. Leaving the "driver's most comfortable" area at the bottom left of the home page for the sound system, we can see that Weilai pays more attention to "sound" than "air conditioning" when arranging icons.
Sound stage, NIO? OS？ 2.7.0? The version has been updated? 5. 1? Channel stereo. In terms of sound source, in addition to supporting routine? QQ？ Music, radio, Bluetooth audio source, USB? External audio source and Himalayan? App？ Even Weilai specially created the exclusive radio station "Nio? Radio] Again, for Weilai users, delivery is just the beginning of everything.
The whole sound system, whether from the sound source access port or using logic, is actually commendable. If you insist on "finding bones in eggs", it's still the same sentence. If there are fewer "screen-grabbing" scenes during use, the experience will be better.
Write it at the end
Based on the strategic trade-off, some features with better experience did not appear on Weilai's current models. However, since I picked up the car for half a year, what I feel most is that Weilai attaches importance to user feedback. Naomi? Good pronunciation, Wei Lai? App？ Ok, you can give Wei Lai feedback and suggestions, and at? 24? Get feedback within hours.
How many times have you experienced this attitude of listening to users' needs? Ota? Is the iteration of the version coming? NIO？ OS？ 2.8.0? After that, Weilai's whole vehicle has a great foundation for improvement in experience.
However, in terms of "no sense of science and technology", it is also an objective phenomenon that the research and development progress of automobile software lags behind friends who are also new forces. As for whether the change of Weilai software team has affected the research and development progress, we have no way of knowing.
Objectively speaking, what if most traditional models are still in use? CarPlay？ As the solution of car machine, then Weilai car machine is still relatively easy to use and scientific in this era.
However, it is worth pondering how Weilai can go faster and better on the next road of software development.
