为车辆系统提供故障缓解的系统和方法
Abstract:
提供了用于在车辆系统中提供故障缓解的系统和方法，所述车辆系统具有高边驱动器（HSD）和低边驱动器（LSD）。本系统包括第一HSD和多个第一LSD。本系统还包括选定的多个第一促动器，其中每个促动器被连接到第一HSD且被连接到第一LSD中的相应的一个，以按第一操作模式操作。本系统进一步包括第二HSD和多个第二LSD。本系统还包括选定的多个第二促动器，其中每个促动器被连接到第二HSD且被连接到第二LSD中的相应的一个，以按第二操作模式操作。当失效的部件设置了一个故障，则相对应的HSD被断开，其他HSD被接通，使得车辆系统能够在无故障操作模式中操作。
Abstract(English):

A system and method for providing fault mitigation in a vehicle system having high side drivers (HSDs) and low side drivers (LSDs) are provided. The system includes a first HSD and a plurality of first LSDs. The system also includes a selected first plurality of actuators, with each actuator connected to the first HSD and connected to a respective one of the first LSDs to operate in a first operational mode. The system further includes a second HSD and a plurality of second LSDs. The system also includes a selected second plurality of actuators, with each actuator connected to the second HSD and connected to a respective one of the second LSDs to operate in a second operational mode. When a failed component sets a fault, the corresponding HSD is turned off and the other HSD is turned on, enabling the vehicle system to operate in the non-faulted operational mode.
