What does PEPS mean in cars?

PEPS in cars refers to the keyless system, which stands for Passive Entry Passive Start system. The function of the keyless system: when the driver steps into a specified range, the system can identify the authorized driver and automatically open the door; when leaving the vehicle, the door locks will automatically lock and enter an anti-theft state. At the same time, the keyless system can also remember all service and diagnostic information, such as seat adjustment, air conditioning settings, entertainment information, etc. The keyless system is a combination of intelligence and convenience, eliminating many cumbersome steps and simplifying car operations. The keyless system mainly operates through four components: door handle switch, low-frequency antenna, car key, and high-frequency receiver. The working principle is as follows: 1. Carry the car key near 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 unlocking or ignition.
PEPS in cars stands for Passive Entry Passive Start, which means a keyless entry and keyless start system. Simply put, if you drive a Hyundai, you can approach the car, pull the door handle, and it automatically unlocks; once inside, just press the brake and hit the start button, and the engine roars to life—no need to fumble for keys or search for the ignition. This feature is highly practical, especially when you're in a hurry or it's raining, making things much more convenient. However, if the car key battery is weak or there's wireless interference nearby, the system might respond slower, so it's recommended to regularly check the key's status, such as replacing the battery. At its core, it relies on the RFID technology in the smart key, and the vehicle processes the signal quickly, significantly enhancing convenience.
