摘　　要：电控适时四驱系统在城市型SUV上得到了越来越广泛的应用.针对某款车辆的适时四驱系统的扭矩管理器及传动系统进行建模,基于dSPACE+Carsim工具设计了硬件在环仿真平台,并对典型工况下的适时四驱控制系统进行了仿真研究.结果表明,所设计的适时四驱控制硬件在环仿真系统完全可以满足系统控制策略开发的需要,为下一步控制系统的开发设计奠定了基础.The electronically controlled on-demand All-Wheel-Drive （AWD） system is increasingly used in urban SUVs. An Intelligent Torque Management （ITM） controller of the system and the transmission of a certain urban SUV are modeled. Based on the dSPACE ＋ Carsim, a hardware-in-the-loop （HIL） simulation platform is designed. The simulation study of the control system is carried out under some typical working conditions. The simulation results show that the designed HIL system can meet the requirements of developing the corresponding control strategies, laying a foundation for the further research on the control system.
