The invention discloses a chassis drifting collision avoidance control method and system and an electronic and electrical architecture, and the method comprises the steps: carrying out the quantitative analysis of collision avoidance demand information through a barrier envelope method, so as to obtain barrier envelope data; calculating a normal operation infeasible state domain of the obstacle envelope data based on a vehicle dynamics model; safety analysis is carried out based on the infeasible state domain of the conventional operation, and whether limit collision avoidance operation is started or not is judged according to a safety analysis result; and if it is judged that the limit collision avoidance operation is started, autonomous decision control of the vehicle is carried out based on limit dynamics control input data generated by the chassis domain control platform so as to achieve drifting collision avoidance. The method can give full play to the collision avoidance potential of the vehicle, and improves the emergency capability and backup level of the intelligent vehicle.

    本发明公开了一种能底盘漂移避撞控制方法、系统及电子电气架构,该方法,包括利用障碍物包络法对避撞需求信息进行量化分析以得到障碍物包络数据;基于车辆动力学模型计算障碍物包络数据的常规操作不可行状态域;基于常规操作不可行状态域进行安全分析,以根据安全分析结果判断是否启动极限避撞操作;判断启动极限避撞操作,则基于底盘域控制平台生成的极限动力学控制输入数据进行车辆的自主决策控制以实现漂移避撞。本发明可以充分发挥车辆的避撞潜能,提升智能车辆的应急能力和备份水平。
