A system for controlling a propulsion system of a vehicle includes a switching system including a first switching device connecting a battery system to a first set of windings of an electric motor, and a second switching device connecting the battery system to a second set of windings. The system also includes a controller configured to transition the propulsion system from an initial propulsion mode in which an initial voltage is applied to the electric motor to a target mode in which a target voltage is applied. The transitioning includes controlling the first switching device to provide current to the first set of windings at an initial voltage to produce torque, and then controlling the second switching device to cause the battery system to apply a target voltage to the second set of windings while providing current to the first set of windings at the initial voltage.
一种用于控制车辆的推进系统的系统包括开关系统,该开关系统包括将电池系统连接到电动马达的第一组绕组的第一开关设备,以及将电池系统连接到第二组绕组的第二开关设备。该系统还包括控制器,该控制器被配置为将推进系统从初始推进模式转换到目标模式,在初始推进模式中,初始电压被施加到电动马达,在目标模式中,施加目标电压。转变包括控制第一开关设备以在初始电压下向第一组绕组提供电流以产生转矩,并且随后控制第二开关设备以使电池系统向第二组绕组施加目标电压,同时在初始电压下向第一组绕组提供电流。
