VEHICLES WITH MULTIPLE HIGH VOLTAGE BATTERIES

A hybrid electric vehicle has one or more controllers, at least two axles independently driven by respective electric machines (EMs) that are each coupled to a separate battery, and a combustion engine (CE) coupled to one of the axles. At least one of the controller(s) are configured to deliver power to one of the axles in a single axle drive mode, and in response to a torque demand signal (TDS) exceeding a single axle power limit, to deliver power to another axle, and/or all axles. The controller(s) are further configured to respond to the TDS exceeding a multiple axle power limit, and to deliver additional CE power to the coupled axle. In response to a braking signal, the controller(s) may also adjust at least one of the EMs to capture mechanical braking energy from a respective axle, and generate negative torque to charge one or more of the separate batteries. 一种混合动力电动车辆，具有：一个或多个控制器；由相应电机(EM)独立驱动的至少两个车桥，所述电机各自联接到单独的蓄电池；以及联接到所述车桥中的一个车桥的内燃发动机(CE)。所述一个或多个控制器中的至少一个控制器被配置为在单桥驱动模式下将功率递送至所述车桥中的一个车桥，并响应于扭矩需求信号(TDS
