What does ASL mean in cars?

[VanLuna]

ASL is the abbreviation for the English term 'automatic-shift-lock,' which represents the gear shift lock device in cars, typically found in automatic transmission vehicles. Below is an introduction to ASL: 1. Its function is to prevent sudden vehicle acceleration. The main feature is that when the car is in normal operation, the driver must press the brake pedal to shift the gear from P (Park) or N (Neutral) to R (Reverse) or D (Drive). This prevents accidentally shifting into forward or reverse gear without pressing the brake, which could lead to accidents. 2. The ASL can control the vehicle speed. When pressed, it sets the current speed as the maximum limit, preventing the vehicle from accelerating further regardless of throttle input. In emergency situations, pressing the throttle fully will trigger a 'click' sound, releasing the speed limit and allowing the vehicle to accelerate rapidly. The ASL is integrated into the entire gear shift system.
