A method of controlling distribution of power to a traction motor of a plug-in electric vehicle having a plurality of on-board power sources. During operation in a normal mode, power is allocated in a normal power control relationship in response to an operator control input. During operation of the vehicle in a normal mode, power is depleted at a first rate. During operation in the derated mode, power is allocated in a derated power control relationship in response to an operator control input. During derated mode operation, power is depleted at a second rate that is less than the first rate to conserve power of the one or more on-board power sources. Responsive to information from the sensor identifying a vehicle condition indicative of a battery charge limit, operation in a derated mode may be initiated.

    一种控制向插电式电动车辆的牵引电动机分配功率的方法,该插电式电动车辆具有多个车载电源。在以正常模式运行期间,响应于操作者控制输入,以正常功率控制关系分配功率。在车辆以正常模式运行期间,功率以第一速率耗尽。在以降额模式运行期间,响应于操作者控制输入,以降额功率控制关系分配功率。在降额模式运行期间,功率以小于第一速率的第二速率耗尽,以节省所述一个或更多个车载电源的功率。响应于来自传感器的信息识别指示电池电量限制的车辆状况,可以发起以降额模式运行。
