What does ASR mean for trucks?

ASR, the Anti-Slip Regulation system, stands for Acceleration-Slip-Regulation. It is an automotive active safety device, also known as the traction control system, designed to prevent wheel slippage during acceleration, especially for high-power vehicles, thereby maintaining driving direction stability. Here are the functions of ASR: The primary purpose is to prevent driving wheel slippage during acceleration, particularly on low-friction surfaces like rain, snow, hail, or icy roads. It controls the slip ratio within a certain range during acceleration to avoid rapid wheel spinning. Its functions include improving traction and maintaining vehicle stability. Here is how ASR works: When driving wheels slip, ASR compares the rotational speeds of all wheels. The electronic system detects the slippage and immediately reduces throttle intake, lowers engine speed, decreases power output, and applies braking to the slipping driving wheels.
