Driving intention management device for electric vehicle

Abstract

The invention relates to a driving intension management device for an electric vehicle. The driving intension management device comprises an accommodation control box body. A top cover is arranged on the accommodation control box body for ensuring the sealing property of the accommodation control box body. The driving intention management device is characterized in that a data exchange terminal assembly is arranged at one side of the accommodation control box body of the driving intension management device for the electric vehicle; and an auxiliary power supply interface is arranged at the other side corresponding to the side of the accommodation control box body. The data exchange terminal assembly is connected with a data bus which is provided with a general interface; the general interface on the data bus is respectively connected with a system start-stop module, an external charging module, a gear-shifting instruction module, a driving direction module, a driving torque module and a brake torque module. The requirements for making correct judgment and operation of a pure electric automobile according to the driving intention of a driving vehicle can be met without being additionally provided with an extra control assembly, thus the driving safety of the vehicle can be improved.

Description

technical field [0001] The invention relates to a management device, in particular to a driving intention management device for an electric vehicle. Background technique [0002] For commonly used vehicles, due to the fault diagnosis function of gear position, accelerator pedal, etc., the vehicle will not experience undesired acceleration, deceleration and reversing. When the main motor and controller fail, the controller will protect itself and stop , the vehicle controller will also reduce the enable signal of its controller and the throttle to 0. When the electrical connection is disconnected unexpectedly, the signal is in the open circuit mode, and the signal is 0, which will not cause danger to the vehicle; and the communication overtime technology is used to ensure that the communication failure caused by the disconnection of the communication line will not cause danger to the vehicle. A manual air circuit breaker is connected in series in the general circuit of the h...
