Electronic shifter with active initialization function, active initialization method of electronic shifter and vehicle

Abstract

The invention relates to an electronic shifter with an active initialization function, an active initialization method of the electronic shifter and a vehicle. The electronic shifter comprises built-in active initialization software; in the software active initialization, a special and unoccupied key combination on an electronic shifter is set as a trigger point; triggering is continued until settime is up, different Baud rates of different built-in vehicle models are tried to be used for being communicated with the whole vehicle; when the proper Baud rate of the whole vehicle is matched, theBaud rate is recorded and written into an EEPROM of the electronic gear shifter, and initialization is ended. If different built-in APPs need to be started according to different vehicle types, afterBaud rate matching is completed, the successfully matched Baud rate is used for communicating with the whole vehicle, the vehicle type code of the whole vehicle is read and written into an EEPROM ofan electronic shifter, and it is determined that the built-in APP of the corresponding vehicle type is started according to the code. The same electronic shifter is used for different vehicle types and configurations to the maximum extent, the number of part varieties is reduced, inventory and waste are reduced, and user-defined settings are prevented from being unexpectedly and forcibly initialized to factory settings.

Description

technical field [0001] The invention belongs to the technical field of electronic shifters, and relates to an electronic shifter with an active initialization function, an active initialization method thereof, and a vehicle using the electronic shifter. Background technique [0002] With the development of new energy vehicles, intelligent driving vehicles, and the electronic development of traditional power vehicle shifting control systems, more and more vehicles use electronic shifters. [0003] In an OEM, in order to realize the platformization and generalization of parts and save costs, there are more and more cases of electronic shifters with the same structure used in different models. Due to different vehicle models and different configurations, such as different CAN communication speeds and partial functional differences of different models, the same electronic shifter is used, so the structure and hardware of the electronic shifter are the same, but the software part...
