Abstract

The invention provides an electronic gear position control system. The electronic gear position control system comprises an electronic gear shifter and a whole car controller. The electronic gear shifter executes the gear shifting operation of a user, obtains a first target gear position corresponding to the gear shifting operation, and returns to the default initial position after gear shifting operation is finished. The whole car controller obtains the current state information of a car, determines that the gear position actually executed by the car currently is the first target gear position when the state information is matched with the first target gear position, and sends the actually executed first target gear position to the electronic gear shifter to be displayed. When the state information is not matched with the first target gear position, a second target gear position actually executed by the car currently is judged according to the state information and the first target gear position, and the actually executed second target gear position is sent to the electronic gear shifter to be displayed. According to the scheme, the electronic gear shifter capable of returning is adopted, the executed gear position is determined through the whole car controller, and the problem that the gear position where an electronic gear shifter handle is located is not consistent with a system gear position is solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to an electronic gear control system and method. Background technique [0002] In recent years, as environmental problems have become increasingly prominent, new energy vehicles with energy-saving and environmental protection advantages have attracted more and more attention, such as green pure electric vehicles and hybrid vehicles that combine environmental protection and power. Electric vehicles are different from traditional vehicles in that they do not have a shifter driven by a mechanical structure, but usually use an electronic shifter controlled by electrical signals. [0003] However, the use of an electronic shifter can easily lead to the problem that the gear position of the shifter handle is inconsistent with the actual gear position of the system. For example, when the shifter performs a wrong shift operation, the vehicle control system does not allow the parking lock If ...
