ACC Adaptive Cruise Adaptive Cruise (ACC) is relatively intelligent, and can generally enter the cruise at low speed. In addition to high-speed road conditions, it can also be applied to urban road conditions and can stop and go.
The sensor (radar) of the car will give instructions to the actuator (throttle, brake and gear) according to the driving state (distance and speed) of the front car and the rear car. After calculation and judgment by ECU, it will decide whether the driving state is accelerating or decelerating or quitting the cruise.
The most basic function of adaptive cruise is to keep the vehicle running vertically. When there is a danger of collision, the vehicle will prompt the driver and take active braking intervention.
Obviously, ACC can alleviate the driver's driving fatigue to some extent.
Back then, if mobile phones were only used for making phone calls, smart phones might never appear. Similarly, looking into the future, cars will not only be used for transportation. "Smart car ecology" helps driving become more and more intelligent. For example, after the emergence of automatic transmission technology, the driver's left foot was "liberated"; The appearance of automatic cruise has liberated the right foot and hands to a certain extent; Car maps bring great convenience to "road idiots"; Connected big data helps people find free parking spaces quickly.
Therefore, the development path of the driverless industry must be like this: the first step is to assist driving; The second cloth, semi-automatic driving; Finally, realize unmanned driving.
