1, ASR, ABS, what are the connections and differences?

Electronic control device and ABS warning light; ASR mainly includes TRC switch, TRC indicator light, TRC stop indicator light and auxiliary throttle actuator.

, TRC brake actuator, TRC and ECU.

The difference between ABS and ASR:

1, ASR and ABS are used to control the wheel sliding relative to the ground, so that the adhesion between the wheel and the ground is not reduced, while ABS is used to control the "dragging" of the wheel, so that the car keeps changing its driving direction when braking, which is mainly used to improve the braking effect and ensure the safety when braking. ASR is used to control the "skid" of wheels, improve the traction during auto start, acceleration and driving on wet roads, and ensure the driving stability.

2. Although ASR, like ABS, can control the braking force of the wheel to suppress the sliding between the wheel and the ground, ASR only controls the braking of the driving wheel.

3.ABS works when the car brakes and locks the wheel, but it doesn't work when the speed is very low, below 8km/h; On the other hand, ASR works when the car is running and when the wheels slip. When the vehicle speed is very high, it generally does not work at 80-120 km/h.

Therefore, the main difference between ASR and ABS is that ABS is to prevent the wheel from slipping when braking, while ASR is to prevent the vehicle from slipping when accelerating. ASR is an extension of ABS, and the two complement each other.
