Regardless of the vehicle equipped with manual transmission or automatic transmission, the driver can cut off the power of the vehicle by pushing the neutral gear (N gear). If pushing the neutral gear is invalid, the driver can also try to turn off the engine-especially starting the vehicle with the key, which will only turn off one gear without losing the steering force and braking force. If the above methods are ineffective, stepping on the brakes vigorously and keeping the brakes (low speed) can help the vehicle slow down.
If the "cruise control" is out of control and the brakes are not working properly, people may first think of "cutting the isolation belt" to slow down, but Professor Liu Shi does not recommend this. Professor Liu Shi said that some highway isolation belts have shoulders below them-square shoulders are vegetation and curved shoulders are drainage. If the vehicle approaches at high speed, it is likely to cause a flat tire and rollover, which is very dangerous.
In fact, there are many sayings about the cruise control system, and each car manufacturer will have a different name. There are three common names: cruise control device, speed control system and automatic driving system.
Constant speed cruise is used to control the constant speed driving of the car. Once the car is set to cruise, the fuel supply of the engine is controlled by the computer, and the computer will constantly adjust the fuel supply according to the road conditions and the driving resistance of the car, so that the car can always run at the set speed without manipulating the throttle.
Generally, this kind of equipment is mostly used for high-speed driving. The advantage is that the driver does not need to control the accelerator pedal, reducing fatigue, reducing unnecessary speed change and saving fuel.
Extended data
Conditions of use
1. In principle, cruise control should be used on expressways or closed roads. Because on non-closed roads, complex road conditions are not conducive to traffic safety. On the national highway, some tractors have insufficient power and often rush to the road at small intersections, posing a serious threat to the cars on the national highway. They are easily caught off guard when cruising at a constant speed. Repeated braking can't maintain a constant and stable cruising state, which loses the meaning of constant speed.
It is forbidden in rainy and snowy days.
3. There are too many detours or detours, which should be banned. Because it is necessary to refuel properly to provide greater steering force under normal detours. When the vehicle is cruising at a constant speed, the speed automatically keeps constant, and the throttle is controlled by the driving computer, which often brings danger to detour driving. In this case, the vehicle speed should be properly controlled.
There are too many vehicles on the road, which is not suitable for cruise control.
Matters needing attention
1. Do not use the speed control system when driving on roads with dense vehicles or poor quality (such as wet roads, loose gravel roads or roads after heavy rain);
2. When the vehicle speed is higher than 40km/h after the system is turned on, do not step on the clutch pedal, that is, move the gear lever to neutral, otherwise the engine may be damaged due to overspeed;
3. If the set cruising speed is too high compared with the traffic conditions at that time, the set cruising speed shall not be restored.
