Shifting handle misoperation prompting method and device of pure electric vehicle

Abstract

The invention discloses a shifting handle misoperation prompting method and device of a pure electric vehicle. The method includes the following steps that running speed, the motor work state and gear information of the pure electric vehicle in the running process are obtained; according to the running speed, the motor work state and the gear information, whether gear engagement misoperation happens to a shifting handle of the pure electric vehicle or not is judged; under the condition that it is judged that gear engagement misoperation happens to the shifting handle of the pure electric vehicle, gear engagement misoperation warning information is generated and sent to prompt a driver of the pure electric vehicle to switch the shifting handle to a correct gear. By means of the method and device, whether gear engagement misoperation happens to the shifting handle of the pure electric vehicle or not can be judged, under the condition that it is judged that gear engagement misoperation happens to the shifting handle of the pure electric vehicle, the warning information is generated and sent to prompt the driver of the pure electric vehicle to switch the shifting handle to the correct gear, and accordingly safety hidden hazards are reduced.

Description

technical field [0001] The present invention relates to the field of pure electric vehicles, in particular to a method and device for prompting misoperation of a shift handle of a pure electric vehicle. Background technique [0002] In recent years, my country's new energy vehicles have received great attention from the state and local governments at all levels, and have made great progress. Pure electric vehicles using pure electric direct drive have been developed rapidly. The electronic shift handle is connected to the vehicle controller as a signal reflecting driving needs (forward, backward, parking), and is widely used in pure electric vehicles. There is a button (lock mechanism) on the traditional shift handle, and the driver needs to press the button to allow the shift, but the electronic shift handle does not have a button. During the driving process of the vehicle, there is a driver's misoperation from the D gear to the N / In the case of R gear or shifting from R ...

AI Technical Summary

Problems solved by technology

Among them, the method can solve the common problem of potential safety hazards caused by the misoperation of the shift handle by the pure electric vehicle driver during the operation of the vehicle by using the obtained relevant information without changing the hardware structure of the shift handle.
