What does the P on the car mean?

[DeAndrew]

The P on the car refers to the electronic parking brake. When pressed, the P on the dashboard lights up red, indicating that the parking brake is engaged. The parking brake is essentially the car's handbrake, which provides resistance when the vehicle is parked to prevent it from rolling. Nowadays, many automatic transmission models are equipped with an electronic parking brake. Working principle of the parking brake: It achieves parking control through the friction generated between the brake disc and brake pads, except that the control method has changed from the traditional mechanical handbrake lever to an electronic button. The electronic parking brake has evolved from the basic parking function to include the AUTOHOLD automatic parking function. This technology allows drivers to avoid prolonged braking when the vehicle is stopped.
