What is the difference between an electronic parking brake and P gear?

[EzraFitz]

The difference between an electronic parking brake and P gear lies in their functions and working principles, as detailed below: Different functions: P gear is the most common gear in automatic transmission models, usually located at the front position of the gearshift console, ahead of the R gear. Its purpose is to lock the axle when the car is stationary on a slope. The electronic parking brake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both using the friction generated between the brake disc and brake pads to control parking braking, except that the control method has changed from the previous mechanical handbrake lever to an electronic button. Different working principles: The electronic parking brake system integrates the temporary braking function during driving with the long-term parking braking function and achieves parking braking through electronic control. P gear evolved from the N gear. In addition to placing the transmission in neutral mode, it also has a pawl inside the transmission that locks the gear on the output shaft to form a mechanical lock, thereby securing the drive axle to fix the vehicle in a stationary or slightly moving state.
