Abstract

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
