基于硬件在环的整车控制器模型建模及仿真

Modeling and Simulation of Vehicle Controller Model Based on HIL

针对新能源汽车控制器开发难的问题,提出建立整车控制器模型作为被控对象,并通过硬件在环进行仿真验证。整车控制器模型采用基于逻辑控制法和查表控制法以及PI控制策略,用MATLAB/Simulink来实现各个汽车模块的建模。为了验证模型精度,选择某一城市公交车为例,模拟实车工况,仿真结果表明:整车控制模型仿真数据与实车测试数据有较高的吻合性,符合新能源汽车标准,能够帮助整车控制器在开发过程中逻辑功能的验证,缩短开发周期。

Aiming at the difficulty and problem of VCU development of vehicle controller,the model of the whole vehicle controller is proposed as the controlled object,and simulation verification is carried out through the hardware in the loop.The vehicle controller model adopts logic control method,table lookup control method and PI control strategy,and uses MATLAB/Simulink to realize modeling of each vehicle module.In order to verify the accuracy of the model,an electric bus is selected as an example and the real vehicle condition is taken as the input.The simulation results show that the simulation data of the whole vehicle control model has a high coincidence with the real vehicle test data,which conforms to the new energy vehicle standard,and can help verify logic function of the whole vehicle controller in the development process and shorten the development cycle.
