What does the P display in a car mean?
1 Answers
The P display in a car indicates that the parking brake is engaged. The parking brake, commonly referred to as the handbrake, is a manually operated brake installed in motor vehicles. It is used to stabilize the vehicle after it has come to a stop, preventing accidents caused by the vehicle rolling on inclined surfaces. The working principle of the parking brake involves a mechanical handbrake system that connects to the rear wheel brake calipers via a cable or similar mechanism. When the handbrake is engaged, the calipers press against the brake pads, thereby achieving the parking function. For electronic parking brakes, activating the parking switch engages a motor that drives the cable or similar mechanism to connect with the rear wheel brake calipers, pressing the calipers against the brake pads to achieve the parking function.
