摘要：

为了减少教练车的燃油消耗以及尾气排放，该文设计了符合驾校使用要求的C1电动教练车动力系统。基于软件开发的V模式，研究了电机模拟发动机点火、怠速、起步、行驶的控制策略及软件实现；将设计的动力系统与控制策略软件以及改进的基于滑模控制的直接转矩控制算法装载到奇瑞凯翼车上，进行了仿真与标定。结果表明：怠速时电机最高转速比发动机低100~200 r/ min, 节省了能耗；起步转速电机比发动机快0.5 s，提高了动力性能；直角、S弯、侧方停车、倒车入库以及科三项目时，与燃油教练车的操控体验基本一致。在石家庄育华驾校进行的与燃油教练车的对比试验，验证了设计的该动力系统及其控制策略的技术可行性。

Abstract:

A power system of C1 electric driver-training vehicles was designed to reduce fuel consumption and exhaust emission to meet the requirements of driving schools. Based on V mode of software development, the control strategy and software realization of a motor simulating engine ignition, idling, starting and running were explored; The designed power system and control strategy software and the improved direct torque control algorithm were loaded into the Chery Kai wing vehicle based on sliding mode control, and the simulation and calibration were carried out. The results show that the motor speed is 100-200 r / min lower than the engine speed at idle speed, saving energy consumption; the starting speed of the motor is 0.5 s faster than that of the engine, improving the power performance; the handling experience of the right angle, S-turn, side parking, reverse parking, and project 3 test is basically the same as that of fuel driver-training vehicles; a comparative test is conducted in Shijiazhuang Yuhua driving school with the fuel driver-training vehicles, which verifies the technical feasibility of the designed power system and its control strategy.

Key words: automotive engineering, C1 electric driver-training vehicle, motor analog engine, C1 driving test, control strategy
