Auxiliary system controller for electric automobile

Abstract

The invention relates to an auxiliary system controller for an electric automobile. The auxiliary system controller comprises a controller operation box; and a box cover is arranged on the controller operation box. The auxiliary system controller is characterized in that a data exchange terminal assembly is arranged at one side of the controller operation box of the auxiliary system controller for the electric automobile; and an auxiliary power supply interface is arranged at the other side corresponding to the side of the controller operation box. Further, an exchange data bus is arranged inthe controller operation box; and a communication end of the exchange data bus is connected with the data exchange terminal assembly. A control end of the exchange data bus is respectively connected with an electric steering control module, an electric air pump control module and an electric air conditioner control module. The normal operation need of each auxiliary system of a pure electric automobile can be met without using extra control assembly. In addition, the adopted module has a simple structure and is convenient for later maintenance. More importantly, the auxiliary system controller disclosed by the invention has better heat radiating performance and the capability of meeting the use requirement for different work conditions.

Description

technical field [0001] The invention relates to an auxiliary system controller, in particular to an auxiliary system controller 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 t...
