Embodiment Construction

[0021]The present invention will be further described below with reference to the accompanying drawings and examples.

[0022]A PEPS controller PE locking method, including the following steps:

[0023]S1. The operator presses the PE button, the PEPS controller identifies the switch signal, and knows the position of the PE button switch;

[0024]S2. The controller controls the front and corresponding door handle four low frequency antennas sequentially sely sequentially sequentially sely sequential positioning frames of the antenna number information;

[0025]S3. The smart key records the low-frequency field of the indoor three antenna and the field power value of the low-frequency antenna in the door handle. The high-frequency data of the three antennas in the room is the largest value of the three antennas of the room. The field power and the key validity data are transmitted; the identity ID of the validity data package hand key and the random encryption authentication information.

[0026]S4. ...

Abstract

The invention discloses a PE locking method of a PEPS controller, which includes: the operator presses the PE button, the PEPS controller recognizes the switch signal, and knows the position of the pressed switch; the controller controls the front, middle, rear and corresponding doors in the car The four low-frequency antennas on the handle continuously send the low-frequency data of the positioning frame with antenna number information; the smart key records the low-frequency field strength values ​​of the three indoor antennas and the field strength value of the low-frequency antenna at the door handle, and uses the same frame of high-frequency data to The field strength value of the three indoor antennas with the largest value and the field strength value of the low-frequency antenna at the doorknob and the key validity data are sent out; after the controller receives the field strength value returned by the high frequency, it calculates the distance between the key and the indoor antenna The distance from the low-frequency antenna at the door handle to determine whether the key is in the car; S5. If the key is not in the car, send a vehicle locking command to realize the keyless leaving function. The invention has the advantages of short communication time, fast response, and reduces the pressure of data communication, and also saves power for the key terminal which has high requirements for low power consumption.

Description

Technical field[0001]The present invention relates to the field of automotive electronics technology, in particular a PEPS controller PE locking method.Background technique[0002]Under the current automotive electronics technology, when the PE function is realized, in order to realize the key of the vehicle area, it is necessary to use three antennas in the car, find it once every antenna, and finally find once through the door handle. "The situation that meets the lock conditions" The situation is no key in the car, which increases the process time of the entire key position confirmation. It has brought uncomfortable shortcomings in the user experience.Inventive content[0003]It is an object of the present invention to propose a PEPS controller PE locking method.[0004]It is an object of the present invention to be implemented by the following technical solution: a PEPS controller PE locking method, including the following steps:[0005]S1. The operator presses the PE button, the PEPS c...
