Program introduction
The traditional car door opening is controlled by the key end to open the door remotely, and the operation is also artificial; the appearance of PKE (PEPS) completely solves this problem. Just put the PKE on the body. When approaching, the vehicle will sense the arrival of the owner and allow the owner to open the door lock. When sitting in the driver's seat, through the system induction, the control authority will be opened, so that the owner only needs to gently turn the ignition switch to perform the ignition and driving action, and does not need to take out the key at all, and naturally does not need to go through. Those annoying and cumbersome moves.
