What is cruise control and what does it do?

The function of car cruising is that when the car is driving at the highest speed, you can turn on the function switch of automobile cruise control system while driving, and the car will stay at the moment of turning on the car cruising function to lock the highest speed and drive at a constant speed.

The driver's right foot can be removed from the accelerator pedal without stepping on the accelerator.

The function of the car cruise control system can relieve the pressure on the right foot that has been stepping on the accelerator. The function of the car cruise control system has a switch button and an acceleration and deceleration button on the steering wheel. For example, the cruising speed is 65,438+000 km/h, and if you press the Add button, the speed will increase by 65,438+00 km/h. ..

Drive at the speed of 1 10 km/h, and press the minus key to reduce the speed of 10 km/h, that is, drive at the speed of 90 km/h under normal circumstances. When the driver presses the brake pedal or returns the transmission to neutral, the constant speed cruise will be automatically released. But in reality, sometimes the cruise control system, the brake and the gearbox fail at the same time, and the driver has to drive at the speed set by the cruise control system. This requires the precautions that Uncle Cat will introduce next. The cruise control system has only a simple constant speed mode.

When this function is turned on within a certain speed range, the vehicle can continue cruising at a certain speed, which enables the driver to vacate his right foot. In this mode, the driver is more likely to feel sleepy than stepping on the accelerator and braking directly to make the vehicle do one less operation. When I drive alone, if I drive late or at noon, I won't turn on the cruise control system, because my arms and legs are dry, so don't move too much. The hypnotic function of expressway is dazzling, and cruise control is controlled by intelligent computer system.

All vehicles equipped with adaptive cruise function are equipped with distance sensors at the front of the vehicle to determine the road ahead. At the same time, the wheel speed sensor receives the vehicle speed signal. The distance sensor can judge the distance between the vehicle and the preceding vehicle, and set it according to the speed of its own vehicle. If the speed of the preceding vehicle is detected to be low, our vehicle can automatically slow down.

At the same time, keep a distance from the front car; If it is detected that there is no obstacle in front of the vehicle, the vehicle will travel at the speed we set. Therefore, adaptive cruise is equivalent to the further upgrade of cruise control function. Constant speed cruise is essentially an auxiliary driving function, which can never replace driving. While liberating your legs, you should not take it lightly, but concentrate on driving. After all, safety first!
