1. Advantages: The maximum power of the internal combustion engine can be determined according to the average required power after the hybrid power is adopted, and the engine is relatively small, so it works under the best working conditions of low fuel consumption and less pollution. Because the internal combustion engine can work continuously and the battery can be charged continuously, its journey is the same as that of an ordinary car.

If it is a pure electric vehicle, the technology is relatively simple and mature, and it can be charged where there is electricity.

2. Disadvantages: The system structure is relatively complicated; The fuel saving effect of long-distance high-speed driving is not obvious.

The energy stored per unit weight of the battery is too little, and because the battery of the electric vehicle is relatively expensive, it does not form an economic scale, so the purchase price is relatively expensive; As for the use cost, some trial results are more expensive than cars, and some results are only 1/7~ 1/3 of cars, mainly depending on battery life and local oil and electricity prices.

Second, smart cars:

1, Advantages: Under complicated and changeable conditions, its "brain" can improvise, automatically choose the best scheme, and command the car to run normally and smoothly.

Smart cars don't need people to drive, but people just sit comfortably in the car and enjoy it.

2. Disadvantages: It is technically difficult, and the final actual test and verification will take a long time.

Extended data:

Basic structure of smart car;

From a concrete and realistic point of view, the mature and predictable functions and systems of smart cars mainly include intelligent driving system, life service system, safety protection system, location service system and automobile service system. All participating enterprises also mainly develop around these functional systems.

Among them, each system actually contains some subdivided systems and functions. For example, the intelligent driving system is a big concept and the most complicated system, which includes: intelligent sensing system, intelligent computer system, assisted driving system, intelligent bus system, etc. The life service system includes audio-visual entertainment, information inquiry and various biological services. For example, location service system can not only provide accurate vehicle positioning function, but also make the car communicate with other cars automatically to achieve the agreed driving purpose.

Smart cars have the same functions as these systems, which is equivalent to installing a TV camera, an electronic computer and an automatic control system with eyes, brains and feet.
