Problems solved by technology

[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 traffic accident

Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0023] see figure 1 , the embodiment of the present invention proposes an electronic shifting device for electric vehicles, the shifting device is arranged on the instrument panel or sub-dashboard, including: a shifting panel 1, a gear controller 2 and a shifting At least four shift switches 3 on the panel 1, any shift switch 3 is provided with a first indicator light and a second indicator light,

[0024] Trigger the corresponding shift switch in the shift switch 3, the shift switch 3 transmits the shift signal to the shift controller 2 through the shift switch signal line 4, and the shift controller 2 receives the shift signal and transmits it through the bus 5 To the vehicle controller 6, the vehicle controller 6 judges whether the shift signal is valid;

[0025] The shift ...

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.
