摘　　要：由于城市交通拥挤,城市车辆常处于怠速工况导致燃油消耗增加,车辆燃油经济性差。为了提高车辆燃油经济性,通过分析汽车怠速停止启动系统工作原理,对系统测控方案进行设计。采用驱动电机模拟发动机工况,利用电磁制动器控制电流实现制动力矩的控制来模拟道路阻力。建立了怠速停止启动系统驱动电机、制动能量回收、制动踏板以及道路阻力模拟的分析模型和测控试验系统模型。利用硬件在环仿真试验系统对所设计的测控系统进行验证,试验结果表明所建立的分析模型及测控方案合理有效,为研究汽车怠速停止启动系统的节能机理及控制策略提供了很好的系统测试平台。Vehicle fuel economy is poor,because the urban traffic is congested,the auto is constantly in the idle condition resulting in the increase of fuel consumption.In order to improve the vehicle fuel economy,the experimental scheme was designed through analyzing the work mechanism of automobile Idling Stopstart System（ISS）.Engine working conditions were simulated by drive motor,the road resistance was simulated through electromagnetic brake controlled current to achieve the control of braking torque.The models of ISS were established,which consists of drive motor,regenerative braking,braking pedal and road resistant simulation.The test system was verified based on hardware in the loop simulation test system.The test results show that the models and the experimental scheme are rational and effective.It is a good testing and simulation platform for the further research on energy-saving mechanism and control technology.
