Abstract

The invention provides a control system for an electric driver-training car. The control system comprises a single-chip microcomputer, a motor driving circuit, a motor rotating-speed measuring circuit, an idle speed adjusting circuit, an electronic accelerator pedal, a brake switch, a neutral gear switch and an ignition switch, wherein the motor driving circuit, the motor rotating-speed measuring circuit, the idle speed adjusting circuit, the electronic accelerator pedal, the brake switch, the neutral gear switch and the ignition switch are connected with the single-chip microcomputer respectively. According to the operation intention of a driver and corresponding sensor signals during operation, the control system for the electric driver-training car analyzes and calculates input signals, simulates the operating condition of a fuel car and controls output of driving signals so as to control the motor rotating speed to meet the operation requirements of the electric driver-training car and keep the working stability of the electric driver-training car. The system has the characteristics of simple hardware structure, stable and reliable data acquisition, high signal timeliness, freedom from lags and the like, a motor can be effectively, stably and quickly controlled conveniently, and the driving feeling of a fuel driver-training car can be realized.

Description

technical field [0001] The invention relates to the power system control of an electric vehicle, in particular to a control system for an electric coach. Background technique [0002] Energy saving and emission reduction has become a global trend. Under the guidance of relevant policies of various countries, the application of electric vehicles is becoming more and more extensive. Due to the special operating conditions of the coach car, the research and development of the electric coach car is more necessary. Electric vehicles use motors and batteries with good traction characteristics as the power system of the entire vehicle. The controller performs the operation control, driving safety and energy distribution of the vehicle to realize the reliable and safe driving of the vehicle. The control system of the existing electric coach car has removed the clutch and transmission, which cannot satisfy the students' learning of the shifting process. At the same time, due to the...
