Electronic gear shifting device for electric vehicles

Abstract

The invention discloses an electronic gear shifting device for electric vehicles. Gear shifting switches transmit gear shifting signals to a gear control unit through gear switch signal lines, the gear control unit receives the gear shifting signals and transmits the same into a vehicle control unit through a bus, and the vehicle control unit judges whether the gear shifting signals are effective or not, wherein if the gear shifting signals are effective, the vehicle control unit achieves gear shifting, outputs successful gear shifting signals and transmits the same to the gear control unit through the bus, and the gear control unit receives the successful gear shifting signals and controls a first indication lamp to send out successful gear shifting prompt information; and if the gear shifting signals are ineffective, the vehicle control unit outputs gear shifting failure signals and transmits the same to the gear control unit through the bus, and the gear control unit receives the gear shifting failure signals and controls a second indication lamp to send out gear shifting failure prompt information through the gear switch signal lines. The electronic gear shifting device for the electric vehicles is simple in structure and easy to operate, availability that drivers operate vehicle gear shifting is achieved by means of button-type operation, and faults and misoperation prompts guarantee safety of vehicle operation of the drivers.

Description

technical field [0001] The invention relates to an automobile shifting device, in particular to an electronic shifting device for an electric automobile. Background technique [0002] At present, there are two types of shifting devices for electric vehicles: one is the mechanical device driving the cable, which is simple and practical, and the price is low, but the mechanical cable-type shifting mechanism is not suitable for the field of electric vehicles; the other is the electronic one. The service life of the shifting mechanism is greatly improved, but the overall volume is large, the installation and maintenance are complicated, the cost is high, and there is no prompt for whether the shift is successful or not. Especially when the vehicle breaks down, the prompt information cannot be given in time, which is easy There is a traffic accident. Contents of the invention [0003] The present invention provides an electronic shifting device for electric vehicles. The devic...
