What does PEPS mean on a car?

[LeCora]

PEPS on a car refers to the Passive Entry Passive Start system, which is a keyless system that allows for intelligent entry and starting. When the driver enters a specified range, the system can identify the authorized driver and automatically unlock the doors. When leaving the vehicle, the doors will automatically lock and enter an anti-theft state. Additionally, the system can remember all service and diagnostic information, such as seat adjustments, air conditioning settings, and entertainment preferences. The working principle of the keyless system is as follows: 1. The driver approaches the vehicle with the key fob. When pressing the vehicle button or pulling the door handle, the vehicle receives a signal to start or unlock and sends a signal to the low-frequency antenna. 2. Upon receiving the signal, the low-frequency antenna sends a low-frequency trigger signal to the key fob. 3. The key fob receives the low-frequency trigger signal and emits a high-frequency unlock signal. 4. The high-frequency receiver receives the unlock signal, and the entire vehicle completes the unlocking or starting process.
