Embodiment Construction

[0041] The technical solution of the present invention will be further explained and described in the manner of specific embodiments below.

[0042] In this embodiment, the engine ECU and the GPS controller are bound to each other through the CAN bus, such as figure 1 shown.

[0043] ①Activate / deactivate the GPS lock function

[0044]1) First, the GPS platform center sends a password request to activate / deactivate the GPS lock function, and then the GPS controller sends the activation / deactivation request message address (FrmMgr_infoIDGPSCtlReqUI_C) through the platform to forward the request to the ECU, and the ECU receives the activation Or after closing the password request, send a randomly generated random number to the GPS module message address (FrmMgr_infoIDGPSCtlRndUI_C) through the ECU to send the generated random number to the GPS controller in the form of a message, and at the same time, the ECU uses the set algorithm to calculate the GPS lock according to the rand...

Abstract

The invention discloses a differential GPS vehicle locking control method, and belongs to the technical field of GPS vehicle locking. For the problem that existing remote vehicle locking method cannotachieve providing of a variety of vehicle locking functions for adapting to different vehicle locking requirements of different whole vehicle manufacturers for GPS, an engine ECU can be enabled to match with multiple different whole vehicle manufacturers by only modifying partial calibration values, and the problem of repeated development of a control program of the ECU is avoided. Multiple calibration parameters are set in the GPS vehicle locking control method provided by the invention, all the whole vehicle manufacturers and dealers can be enabled to have own locking strategies and different vehicle locking / unlocking performance thereof by only modifying certain calibration parameters set in advance in the engine ECU, basic vehicle locking requirements of the whole vehicle manufacturers and the dealers can be met, and repeated development of the engine ECU program can also be avoided.

Description

technical field [0001] The invention relates to the technical field of GPS loan car lock, in particular to a method capable of meeting differentiated GPS car lock requirements of different vehicle manufacturers. Background technique [0002] Among the existing GPS car locking solutions, there is no method that can meet the different car locking requirements of different car manufacturers for GPS without redeveloping the program for an engine ECU. [0003] A representative method at present is introduced in "A Method for Remotely Locking a Car" (CN108944785A). Usually the GPS controller and engine ECU are connected by CAN bus. The platform center sends control signals to the GPS controller remotely, and the GPS then sends the signals to the ECU, and interacts with the ECU to realize the following functions: [0004] (1) GPS sends a lock command to the ECU, and the ECU limits the engine speed or torque after receiving the command. [0005] (2) The GPS sends an unlock comman...
