Some time ago, the enhanced driver assistance system of Che Yun BMW 540Li was tested. Considering the limitations of the existing technology, the perception of the surrounding environment of the vehicle itself can only be realized by sensors such as radar and camera, which also makes different brands think differently about the decision-making scheme of intelligent driving and the restrictions on different scenes. Therefore, Che Yun first affirmed the positive side of the worksheet of the system's evolution to intelligent driving technology, but combined with the intelligent driving assistance technology of the same class vehicle that Che Yun's editorial department had contacted before, the ADAS system on 540Li was analyzed objectively.
First of all, let's take stock of the hardware composition of the enhanced driver assistance system on this BMW 540Li. In terms of sensor richness, if we compare the enhanced driver assistance system of this BMW 540Li with the so-called first automatic driving A8 that reaches L3 level, we will not give the system a high degree of redundancy (mainly the number of sensors) except for the lack of a 4-wire laser radar (currently, the laser radar that meets the requirements of vehicle regulations is only a 4-wire model).
Of course, for Che Yun bacteria, the most practical significance of this enhanced driver assistance system on the 540Li is that it covers most of the new 5-series vehicles, and truly achieves the ultimate goal of making "technology" available to the people, compared with the current situation that other brands only carry it on top-of-the-line vehicles and even require consumers to choose.
Next, let's take a look at the performance of this 540Li in the actual road test: Considering that this system can almost monitor various working conditions and environments of vehicles from standstill to 2 10 km/h, it is not surprising that Che Yun found that it can provide very reliable and excellent performance under normal circumstances. In fact, in many special cases, this BMW 540Li has been done with sensors.
For example, using millimeter-wave radar distributed around the car body, 540Li can fully detect the surrounding obstacles when the car is driving in a "dense" street or reversing, and can actively brake to stop the car when it is about to encounter obstacles, and at the same time, it will not provide frequent control intervention to the driver when passing through obstacles, which is very annoying. In the process of continuous testing, Che Yun was really impressed by the accuracy and reliability of his work.
