What does the 'A' circle mean on a car?
1 Answers
An 'A' circle on a car stands for AUTOHOLD, indicating that the vehicle is equipped with an automatic parking function. For example, when encountering a red light at an intersection, if the car remains stationary for 1 to 2 seconds, the parking brake will automatically engage. The automatic parking system operates by utilizing the extended functionality of the electronic parking brake within the brake management system to control all four-wheel brakes. The implementation of this system is not simply achieved through the electronic parking brake alone. When parking on slopes or at traffic lights, drivers typically use the parking brake. Relying solely on the electronic parking brake in such scenarios would result in slower response times, as activating it requires both a prerequisite brake pedal action and button response time, along with a relatively long motor operation duration of approximately 0.5 seconds.
