What is the function of the Anti-Slip Regulation (ASR)?

The function of the Anti-Slip Regulation (ASR) system is to control the slip within a certain range during vehicle acceleration, preventing the drive wheels from slipping excessively, thereby improving the directional stability and steering control capability of the vehicle during braking. The ASR system enhances traction and maintains the driving stability of the vehicle. On slippery roads, vehicles without ASR are prone to wheel spin during acceleration; rear-wheel-drive vehicles may experience fishtailing, while front-wheel-drive vehicles may lose directional control. With ASR, the vehicle can either prevent or mitigate such phenomena during acceleration. The principle is that when the computer detects a drive wheel slipping, it automatically reduces the engine's power output and applies braking to the slipping wheel until normal wheel rotation is restored. The role of ASR is to control the tire slip rate within a certain range during acceleration, preventing the drive wheels from losing power due to slipping or causing safety issues due to excessive power output. One of its functions is to improve traction, and the other is to maintain stable vehicle operation. On slippery roads, vehicles without ASR are prone to wheel spin during acceleration; rear-wheel-drive vehicles may fishtail, while front-wheel-drive vehicles may lose directional control. With ASR, the vehicle can either prevent or mitigate such phenomena during acceleration.
