The invention discloses an electric carrying equipment drive-by-wire chassis multi-domain collaborative anti-rollover control method, which comprises the following steps of: 1, constructing a rollover risk assessment and control strategy selection method, and calculating key parameters such as yaw velocity and lateral acceleration of a vehicle in real time; step 2, based on the rollover risk index model and the rollover critical threshold in the step 1, establishing a multi-domain collaborative rollover prevention control model, and performing collaborative scheduling on independent steering, hub motor differential steering and an ESP brake control system; step 3, based on the multi-domain collaborative anti-rollover control model in the step 2; and 4, based on the priority dynamic allocation and control strategy execution result in the step 3, the central control unit coordinates the complex interaction relationship among the subsystems by using a fuzzy logic control algorithm. The invention provides a reliable control strategy priority and use frequency method, and provides a more reliable anti-rollover solution for the electric carrying equipment under a complex dynamic working condition.

    本发明公开了一种电动运载装备线控底盘多域协同防侧翻控制方法,包括以下步骤:步骤一:构建侧翻风险评估与控制策略选择方法,通过实时计算车辆的横摆角速度、侧向加速度等关键参数;步骤二:基于步骤一中的侧翻风险指数模型和侧翻临界阈值,建立多域协同防侧翻控制模型,通过对独立转向、轮毂电机差速转向和ESP制动控制系统的协同调度;步骤三:基于步骤二中的多域协同防侧翻控制模型;步骤四:基于步骤三中的优先级动态分配和控制策略执行结果,中央控制单元利用模糊逻辑控制算法协调各子系统间的复杂交互关系。本发明提供了可靠的控制策略的优先级和使用频率方法,为电动运载装备在复杂动态工况下提供了更加可靠的防侧翻解决方案。
