Controller of whole electric automobile

Abstract

The invention discloses a controller of a whole electric automobile. The controller comprises a single-chip microcomputer, a power supply module, a switch signal acquiring circuit, an analog signal acquiring circuit, a driving circuit, a CAN communication interface circuit and a frequency signal acquiring circuit, wherein the input port of the single-chip microcomputer is connected with output signals of the power supply module, the switch signal acquiring circuit, the analog signal acquiring circuit and the frequency signal acquiring circuit, and the output port of the single-chip microcomputer is connected with input signals of the driving circuit and the CAN communication interface circuit. Through the adoption of the controller disclosed by the invention, the intellectualized regulation and control of regenerative braking systems is realized; two kinds of cooling modes can be controlled to separately or simultaneously work according to the working conditions of the whole electric automobile and a motor; whether an air conditioner can be started or not can be judged according to the request switch of the air conditioner and the running conditions of the whole electric automobile; the controller can be combined with traffic jam signals so as to lower the frequency of the air conditioner when the traffic jam occurs; whether an electric power-assisted steering and electric air compressor needs to be started can be judged according to the running conditions of the whole electric automobile, so that the energy conservation and high efficiency of the whole electric automobile system can be guaranteed, the functions are comprehensive, and the integration level is high.
