Embodiment 1

[0015] The PEPS system of this embodiment includes a key entry and start control module, a body control module (BCM), a low-frequency antenna inside a car, a low-frequency antenna outside a car, a door handle button, a door lock switch, a combination instrument, and a horn, wherein the low-frequency antenna inside a car has Four antennas are arranged in the cab, and the low-frequency antennas outside the car are respectively arranged at the rear bumper and the door handle of the car to ensure that there is no blind spot to detect the key, so as to accurately detect the position of the key. The security strategy based on the PEPS system includes the following two situations of locking and unlocking:

[0016] Keyless car lock:

[0017] When the door lock is unlocked, after the keyless entry and start control module receives the lock signal, the body control unit detects the position of the key through the low-frequency antenna inside the vehicle and the low-frequency antenna out...

Abstract

The invention provides a safety strategy based on a PEEPS system so as to avoid the situation that an external person without a key enters a car illegally. The safety strategy includes the specific steps of keyless car locking, wherein a keyless entrance and start control module detects the position of a key after receiving a car locking signal, the keyless entrance and start control module stops locking of a door lock if only one key is detected and the key is located inside a car, and the keyless entrance and start control module allows locking of the door lock if keys are detected inside and outside the car at the same time and the car locking signal is a remote control car locking signal of the key located outside the car; keyless unlocking, wherein the keyless entrance and start control module detects the position of a key after receiving an unlocking signal, the keyless entrance and start control module allows unlocking of the door lock if a key is detected outside the car, and the keyless entrance and start control module stops unlocking of the door lock if only one key is detected and the key is located in the car.

Description

technical field [0001] The invention relates to the technical field of keyless entry and start systems, in particular to a security strategy based on a PEPS system. Background technique [0002] At present, the keyless entry and start system (PEPS) has been widely used in various models. The owner does not need to take out the key, but only needs to touch the button of the door handle with his hand to enter the vehicle very conveniently. Although this method of entry is very convenient, there are also security risks. If there is no perfect strategy, the keyless entry and start system may have the following problems: if the key is forgotten in the car, when someone touches the button of the door handle outside the car, the system will detect that there is a key and open the car door lock, resulting in illegal entry of outsiders. Contents of the invention [0003] The purpose of the present invention is to propose a security strategy based on the PEPS system to prevent out...
