What does the 'a' behind the electronic parking brake in a car mean?

[OCaleb]

The 'a' behind the electronic parking brake in a car stands for 'autohold', which is the automatic parking system. After turning on the automatic parking system, when waiting at a red light, you don't need to shift into neutral or pull the handbrake—the car will remain stationary without rolling. When the light turns green, stepping on the accelerator pedal will make the car move forward. This system is particularly suitable for urban roads with frequent traffic lights. With the automatic parking system, when waiting at a red light, you only need to bring the car to a complete stop and then press the brake pedal firmly once. The system will activate, eliminating the need to pull the handbrake or keep your foot on the brake pedal, and the car will not roll.
