What does PEPS mean in cars?

[DiSarah]

PEPS in cars refers to the keyless system, also known as the Passive Entry Passive Start system. The function of the keyless system is simply that when the driver steps into a designated range, the system can recognize the authorized driver and automatically open the door; when leaving the vehicle, the door locks will automatically lock and enter an anti-theft state. The working principle of the keyless system is as follows: 1. Carry the car key to the vicinity of the vehicle (the car key must have power), when pressing the vehicle button or pulling the door handle, the vehicle will receive the ignition or unlock signal and send a signal to the low-frequency antenna. 2. After receiving the signal, the low-frequency antenna will send a low-frequency trigger signal to the car key. 3. The car key receives the low-frequency trigger signal and sends a high-frequency unlock signal. 4. The high-frequency receiver receives the high-frequency unlock signal, and the entire vehicle completes the unlocking or ignition process.
