Electronic control engine sensor abbreviation English

1.TCS: TCS is the abbreviation of English Traction Control System, and Chinese "tracking control system" is a control system to prevent tires from slipping and idling. The motive power of automobile movement comes from the traction of tires, which is driven by engine and gearbox. When the car is about to start, the traction will increase with the increase of throttle and engine speed, but it has a limit, that is, once the friction between the tire and the ground is exceeded, the tire will start to slip and idle in place. At this time, the waiting will not move, and the tires will emit a lot of white smoke. It will take a while for the car to snake out. In fact, it is not good for the car to increase the throttle and let the tires idle, because it will cause the danger of hunting cars; Second, the tire will wear seriously, shortening the service life of the tire; Third, waste precious gasoline; 4. Driving on slippery roads, muddy roads, sand or snow, due to poor tire grip, stepping on the accelerator and large tire traction, it is easy to cause tires to slip and idle, and the car is out of control, causing accidents. The working principle of TCS is to monitor the rotational speed of all tires with ABS sensors. As long as the driving wheel starts to slip and idle, and the speed is higher than other tires to reach the set limit, the computer on the car will automatically release the throttle or brake, so that the traction and speed of the driving wheel will be reduced, the phenomenon of slipping and idling will disappear, and the vehicle can resume normal handling and driving stability. Usually at this time, the driver's right foot will feel a strong reverse thrust when stepping on the accelerator, and the TCS control light on the dashboard will start flashing.

2.ABS: English abbreviation for anti-lock braking system, which means "anti-lock braking system". Without ABS, the four wheels are completely locked when the car brakes suddenly. At this time, as long as the car is subjected to a little lateral force (such as sloping road or pebbles on the ground), it will slip, and the car will swing violently or even turn around completely; What is more dangerous is that when the car is driving in a corner, it will lose its steering ability because the front wheel is locked. At this time, although turning the steering wheel can also drive the front wheels to turn, the car can't turn because of the lack of adhesion of the wheels, but moves along the inertia direction until it stops. With ABS, wheel locking can be controlled by controlling the release of brake oil pressure. When the wheel brakes, the sensor installed on the wheel can immediately sense whether the wheel is locked and send the signal to the computer. The computer will immediately reduce the braking force of the locked wheel, and the wheel will continue to rotate to a certain extent, and the computer will apply the brake to ensure that the wheel is braked without locking, and so on until the car comes to a complete stop. The computer can detect the wheels hundreds of times in one second, and operate the braking system dozens of times at the same time, so that the vehicle is always in the critical locking gap rolling state in the cycle of "locking-releasing-locking-releasing". The car equipped with ABS can significantly improve the braking performance of the car and has certain steering avoidance ability.
