What does ASR mean on a car?

ASR on a car is the abbreviation for Anti-Slip Regulation, also known as the Traction Control System. ASR is an active safety device in vehicles, designed to prevent wheel slip, especially in high-power vehicles during startup and acceleration, thereby maintaining the stability of the vehicle's direction of travel. ASR is a set of anti-slip control systems adopted after ABS, representing a further development and important supplement to ABS functionality. Functions of ASR: 1. Prevent driving wheels from slipping during vehicle startup and acceleration; 2. Prevent driving wheels from spinning on asymmetrical road surfaces or during turns; 3. Improve traction and maintain the vehicle's driving stability, keeping the slip ratio within the range of 10% to 20%.
I often hear the term ASR in car usage, which stands for the Acceleration Slip Regulation system. Simply put, it's a function that helps prevent wheel slippage during acceleration. When the car starts accelerating on slippery roads or slopes, ASR monitors wheel speed through sensors. If it detects a wheel spinning too fast, it automatically intervenes by applying brakes or reducing engine power to maintain vehicle stability and prevent skidding. This is similar to ESP, but while ESP primarily controls overall stability, ASR focuses more on safety during the initial acceleration phase. I remember last winter when driving in the snow, ASR prevented my car's rear wheels from spinning out, which was really practical. Many modern vehicles come equipped with this system as it reduces accident risks, especially during rainy or snowy conditions. You might not notice it in normal driving, but once activated, it can prevent potential dangers.
