What is the difference between cruise control and adaptive cruise control?
Constant speed cruise, as its name implies, can set a certain speed, and the English letter is CCS, which is mostly used at high speed. When in use, as long as the speed is set, the vehicle will run at the set speed. If the vehicle is close to the front, the driver needs to step on the brakes to keep a safe distance.
Once the constant speed cruise is set, the foot can temporarily leave the accelerator pedal. When the vehicle encounters an uphill slope, it will accelerate to maintain the set speed. When it encounters a downhill slope, it will adjust the throttle to increase the engine speed to achieve the purpose of slowing down. Generally, cruising can only be used when the speed is above 30 per hour.
Adaptive cruise, English letter ACC. Since adaptive cruise is an upgraded version of cruise control, it is more flexible and intelligent to use. If constant speed cruise liberates the feet, then adaptive cruise is close to automatic driving. Adaptive cruise radar can scan the surrounding traffic conditions and judge whether the vehicle is accelerating or decelerating, thus maintaining a safe driving distance, which is a very good driving assistance.
In adaptive cruise, a radar and a three-eye camera are added to identify the vehicle in front. The vehicle can judge whether it is accelerating or decelerating through these sensors, and can adjust its own speed. Therefore, after the adaptive cruise is started, the front car will slow down and the rear car will slow down, and the front car will accelerate and the rear car will accelerate, which greatly reduces the driver's fatigue driving.
Although adaptive cruise plays a very important role in assisting driving, most adaptive cruises cannot identify stationary vehicles or vehicles that have stopped at traffic lights, so drivers need to step on the brakes in time to stop the vehicles. If your car keeps following the car in front and the car in front stops, then your car will also stop.
Although adaptive cruise can realize its own acceleration and deceleration, it still needs the driver's own control in an emergency. For example, if someone forces traffic jams, such as bad weather such as ice and snow, it is suggested not to expect adaptive cruise, and it is obviously the most unwise choice to entrust people's safety to adaptive cruise.
The use of fixed-speed cruise and adaptive cruise is actually very simple. Generally speaking, the buttons are on the steering wheel. If you really can't use them, you can look at your own car manual, or ask the salesperson in the 4S shop to explain.
