Problems solved by technology

In the past, electric vehicle control technology only had one control mode, but different people have different driving habits, or due to objective reasons, the vehicle needs to work according to different performances. At this time, a single working mode cannot meet the requirements of users.

Embodiment Construction

[0014] The multi-working mode selection device for an electric vehicle of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0015] In the multi-working mode selection device of the electric vehicle of the present invention, the vehicle controller controls the working state of the motor by receiving different power supply input switch signals. For example, when the driver needs to reach the destination quickly when encountering an emergency or needs a higher acceleration performance of the vehicle due to other special requirements, the present invention can be used to choose to enter the emergency mode to improve the related performance of the vehicle, such as reducing the impact on the battery and motor. The degree of protection, ignoring some general faults, giving priority to reaching the destination as soon as possible; when the vehicle is in energy-saving mode, it will increase the mileage and protec...

Abstract

The invention discloses a multi-operating mode selection device for an electric automobile. A power input end of a vehicle control unit is connected with a multi-power input selection switch; the switch is provided with a resistor R1, a resistor R2 and a resistor R3 which are connected in series with one another; the other end of the resistor R1 is connected with a 5V power supply; the other end of the resistor R3 is grounded; a normal mode power input switch is arranged between the resistor R1 and the 5V power supply; an emergent mode power input switch is arranged between the resistor R1 and the resistor R2; an energy-saving mode power input switch is arranged between the resistor R2 and the resistor R3; a constant speed mode power input switch is arranged between the resistor R3 and the ground; and one end of a selection key is selectively connected with selection ends of the normal mode power input switch, the emergent mode power input switch, the energy-saving mode power input switch and the constant speed mode power input switch, and the other end of the selection key is connected with the power input end of the vehicle control unit. By the device, a vehicle can operate in a normal mode, an energy-saving mode, an emergent mode, a constant speed mode and other operating states.

Description

technical field [0001] The invention relates to an electric vehicle. In particular, it relates to a multi-working mode selection device for an electric vehicle that improves the operability of the vehicle by setting multiple control modes for the electric vehicle. Background technique [0002] As the country's investment in electric vehicles continues to increase, electric vehicle technology has developed rapidly. Due to the gradual maturity of the control technology of electric vehicles, the application fields of electric vehicles have been further expanded. People's requirements for electric vehicles are also becoming more and more stringent. In the past, electric vehicle control technology only had one control mode, but different people have different driving habits, or due to objective reasons, the vehicle needs to work according to different performances. At this time, a single working mode cannot meet the requirements of users. Contents of the invention [0003] T...
