Embodiment Construction

[0024] In the existing automobile technology, for some middle and low-end cars or some cars with a long production year, the PEPS system is not equipped, and users can install the PEPS system according to their own needs. For vehicles equipped with the PEPS system, the PEPS system communicates with the body controller BCM through the CAN bus to realize the function of keyless entry. However, the existing keyless entry solution has the problem of long wake-up time of the vehicle network.

[0025] In the embodiment of the present invention, waking up the BCM through the LIN bus can effectively save the waking time of the BCM; sending the door operation instruction and the first key to the BCM through the LIN bus can speed up the information interaction between the PEPS controller and the BCM, Therefore, the wake-up time of the vehicle network in the keyless entry scheme can be effectively reduced.

[0026] In order to make the above objects, features and advantages of the embod...

Abstract

A vehicle keyless entry method and system, the keyless entry method comprising: a PEPS controller receives a door handle switch sensor signal, wakes up a CAN bus, and wakes up a BCM through a LIN bus; the PEPS controller sends a signal to the BCM through a LIN bus The door operation command and the first key; the PEPS controller wakes up the key and sends the second key to the key; the BCM receives the door operation command, the first key and the key pair The third key generated after encrypting the second key is used to authenticate the first key and the third key, and when the authentication is successful, perform a corresponding operation according to the door operation instruction, so The above door operation command is related to the status information of the vehicle after the last keyless entry operation. By adopting the method and system, the vehicle network wake-up time in the keyless entry scheme can be effectively reduced.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a vehicle keyless entry method and system. Background technique [0002] With the continuous advancement of electronic technology, modern cars are becoming more and more intelligent. The keyless entry and start (Passive Entry and Passive Start, PEPS) system can complete the opening and locking of the car door according to the smart key carried by the car owner. After entering the car, you only need to turn on the start button to complete the start of the car. Reduce the steps and time of traditionally unlocking the door to start the vehicle. [0003] In the existing automobile technology, many automobile manufacturers and dealers use the PEPS function as an optional function, and users can decide whether to install the PEPS system according to their own needs. For vehicles equipped with the PEPS function, the PEPS system communicates with the Body Control Module (BCM) through the Cont...
