摘　　要：为研究分布式驱动电动车(DDEV)自适应巡航行驶稳定性,基于CarSim和Simulink联合仿真搭建了DDEV自适应巡航控制算法模型和车辆稳定性控制策略模型。搭建车辆动力学模型得到附加横摆力矩;根据自适应巡航控制原理搭建自适应巡航控制算法模型,得到纵向行驶分布式驱动电机期望力矩,通过差动驱动方式对DDEV的期望力矩进行分配;基于Simulink和CarSim联合仿真,在柏油路面和对开直线路面上对稳定性控制策略进行模型在环验证。结果表明:所提出的控制策略可以有效地控制DDEV的横摆运动,提高了整车的行驶稳定性。In order to study the adaptive cruise vehicle driving stability of distributed drive electric vehicle(DDEV),this paper builds the DDEV adaptive cruise algorithm model and vehicle stability control strategy model based on the joint simulation of CarSim and Simulink.The vehicle dynamics model is first built to obtain the additional transverse moment.Building the adaptive cruise control algorithm model according to the adaptive cruise control principle is followed to gain the longitudinal driving distributed drive motor desired torque.And the desired torque of the DDEV is distributed through the differential drive method.Based on the joint simulation of Simulink and CarSim,the stability control strategy is verified in the loop on the tarmac and the opposing straight road.The results show that the proposed control strategy can effectively control the cross-swing motion of the DDEV,thus improving the driving stability of the vehicle.
