The invention relates to a high voltage traction system for a vehicle. A high voltage traction system for a vehicle includes two independently controllable power subsystems, namely a powertrain power subsystem (PPS) and a vehicle power subsystem (VPS), the PPS including a plurality of PPS secondary power consumers and a PPS master controller configured to arbitrate power limits among the PPS secondary power consumers by a first arbitration logic, the PPS master controller being configured to arbitrate power limits among the PPS secondary power consumers by a second arbitration logic, and the PPS master controller being configured to arbitrate power limits among the PPS secondary power consumers by a second arbitration logic. And the VPS includes a plurality of VPS secondary power consumers and a VPS master controller configured to arbitrate a power limit among the VPS secondary power consumers by a second arbitration logic different from the first arbitration logic. The system also includes a primary interface between the PPS master controller and the VPS master controller, enabling a communication exchange between the PPS and the VPS, the communication exchange including system sharing instructions of the PPS secondary power consumer and the VPS secondary power consumer that limit prioritization of the first arbitration logic and/or the second arbitration logic in a restricted state.
本发明涉及车辆的高压牵引系统。本发明涉及一种车辆的高压牵引系统,包括:两个可独立控制的电力子系统,其为动力总成电力子系统PPS和车辆电力子系统VPS,PPS包括多个PPS次级电力用户和PPS主控制器,PPS主控制器被配置为通过第一仲裁逻辑对PPS次级电力用户当中的电力限制进行仲裁,并且VPS包括多个VPS次级电力用户和VPS主控制器,VPS主控制器被配置为通过不同于第一仲裁逻辑的第二仲裁逻辑对VPS次级电力用户当中的电力限制进行仲裁。系统还包括主接口,主接口在PPS主控制器与VPS主控制器之间,实现PPS与VPS之间的通信交换,通信交换包括PPS次级电力用户和VPS次级电力用户的在限制状态下限制第一仲裁逻辑和/或第二仲裁逻辑的优先化的系统共享指令。
