The invention belongs to the field of automobile numbers, and particularly relates to a method for achieving stability control over a double-independent-motor electric automobile based on IFOC. Comprising the following steps: step 1, determining an electric vehicle coordinate model; 2, performing vehicle dynamics analysis according to the electric vehicle coordinate model to obtain key parameters in the running process of the electric vehicle; and thirdly, the torque of front and rear wheels is controlled through all key parameters in the running process of the electric automobile, and therefore the stability of the double-independent-motor electric automobile is controlled. According to the control method, an optimized limit is provided for the torque level generated by the front motor and the rear motor, the limit is proportional to the road condition, a driver can be assisted in safe driving in the vehicle driving process, and the vehicle is prevented from slipping and being unstable when decelerating on a sliding road.
本发明属于汽车数领域,具体的说是一种基于IFOC实现双独立电机电动汽车稳定性控制的方法。包括以下步骤:步骤一、确定电动汽车坐标模型;步骤二、根据电动汽车坐标模型,进行车辆动力学分析,得到电动汽车运行过程中各个关键参数;步骤三、通过电动汽车运行过程中的各个关键参数控制前后轮的扭矩,从而对双独立电机电动汽车的稳定性进行控制。本发明为前后电机产生的扭矩水平提供了一个优化的限制,与路面状况成比例,能够辅助驾驶员在车辆行驶中安全行驶的控制方法,防止车辆在滑路上减速时打滑和不稳定。
