摘要： 针对传统牵引力控制系统无法满足赛车极限工况的情况，提出考虑空气动力学套件的某款FSAE赛车牵引力控制系统。通过Fluent完成对整车空气动力学套件的流体仿真计算，进而在Carsim中建立符合其空气动力学特性的车身子系统模型，解决了Carsim中无法建立赛车空气动力学套件模型的问题。根据赛车极限工况，设计开发了模糊PID控制器，通过模糊PID控制替代传统PID控制，实现PID参数的自适应，并在Carsim与Simulink的联合仿真平台上进行牵引力控制系统的动态仿真。最终，实车试验表明滑移率始终稳定在最佳值附近，动力响应满足赛事极限工况的要求。

Abstract: For the traditional method of traction control system can not meet the requirements of the extreme operating conditions of the racing car, this paper puts forward the traction control system based on a FSAE racing car which considers aerodynamic kit. The Fluent completed computational fluid dynamics of the vehicle aerodynamic kit, and then established a body subsystem model in Carsim that matches its aerodynamic characteristics. It solved the problem that the aerodynamic kit of racing car can not be established in Carsim.According to the extreme condition of the racing car, the fuzzy PID controller was designed.The traditional PID control was replaced by the fuzzy PID control to realize the selfadaptation of the PID parameters.After that, the cosimulation platform was built with Carsim and Simulink,and simulation of the traction control system was processed on it.Finally,through the vehicle test, it was verified that the slip was always near the optimal slip, and the dynamic response met the requirements of the extreme conditions of the competition.
