Acceleration Slip Regulation (ASR) is the acceleration slip regulation (traction control) or drive anti-skid system. The purpose of ASR is to prevent the driving wheels from slipping during starting and accelerating, especially in high-powered cars, and to maintain stability in the vehicle’s driving direction.
ASR can control traction by reducing engine power by reducing throttle opening or by using brakes to control wheel skid.
On ASR vehicles, the mechanical connection from the accelerator pedal to the throttle (the diesel fuel injection pump lever) is replaced by an electronically controlled throttle device. When sensors transmit signals about the position of the accelerator pedal and wheel speed to the control unit, the control unit generates a control voltage signal.
The servo motor adjusts the throttle position (or the position of the diesel engine joystick) according to this signal, and then feeds the position signal back to the control unit to adjust the brake in time.
When the car is driving on the slippery road, the driving wheel of the car without ASR is easy to slip when accelerating. If the rear driving wheel slips, the vehicle is easy to throw the tail. If the front driving wheel slips, the direction of the vehicle is easy to lose control.
With ASR, the car does not have or can mitigate this phenomenon when accelerating.
When turning, a drive wheel skid will cause the entire vehicle to shift sideways, and when ASR is present, it will turn the vehicle along the correct route.
In summary, the ASR maximizes the driving torque of the engine to ensure the stability of the vehicle during starting, accelerating and steering.
