摘要： 针对中国大学生电动方程式大赛（FSEC）赛车电驱系统的匹配设计，文章通过理论计 算与车辆动力学仿真相结合的方式为赛车匹配一套能够达到整车性能目标参数的电机、电机 控制器及电池组；使用 OptimumLap 软件搭建赛车和赛道模型，仿真得到最佳传动比为 3.95； 使用 CarSim 软件进行车辆动力学仿真，根据理论计算得到的相关参数搭建出赛车模型，仿真 模拟得到 0－75 m 直线加速的时间为 5.24 s，22 km 耐久赛后动力电池的荷电状态（SOC）为 22%，符合设计要求。此套 FSEC 赛车电驱系统匹配设计合理。

Abstract: For the matching design of the electric drive system for the formula student electric China (FSEC) racing car, this paper by a way that combines theoretical calculations with vehicle dynamics simulation to match a set of motor, motor controller, and battery pack that can achieve the target performance parameters of the vehicle. Using OptimumLap software, a racing car and track model is built, and the simulation shows that the best transmission ratio is 3.95. CarSim software is used for vehicle dynamics simulation, and a racing car model is built based on the relevant parameters obtaines from theoretical calculations. Simulation show that the time for 0－75 m straight-line acceleration is 5.24 s, and the state of charge (SOC) of the power battery after a 22 km endurance race is 22%, which meets the design requirements. This set of FSEC racing car electric drive system matching design is reasonable.
