What does ASR mean in cars?
2 Answers
ASR in cars refers to the Anti-Slip Regulation system, also known as the Traction Control System, which is an active safety device in vehicles. The functions of ASR include: 1. Preventing drive wheel slippage during vehicle starting and acceleration; 2. Preventing drive wheel spin on asymmetric road surfaces or during turns; 3. Improving traction and maintaining driving stability, while keeping the slip ratio within the range of 10% to 20%. The electronic controller and brake pressure regulator in ASR can be shared with ABS, so ASR and ABS are often used together to form a system with both anti-lock braking and drive wheel anti-slip control functions.
I first heard about ASR when discussing rainy day driving with a friend. He told me its full name is Acceleration Slip Regulation system, abbreviated as ASR in English. This system is particularly smart, specifically managing the power output of the engine. For example, when you press the accelerator in snow and the tires start spinning wildly, it immediately reduces engine speed to provide steady thrust. What I appreciate most is when driving on muddy roads - the moment the wheels attempt to spin freely, the system intervenes, keeping the car body remarkably stable. Some premium vehicles even come equipped with wheel speed sensors that integrate with the braking system for coordinated control. After five years of driving an ASR-equipped car, I've noticeably gained more confidence when overtaking on slippery roads.
