本发明涉及用于切换可变电驱动车辆的扭矩和电流控制方法。一种电流命令模块被构造成基于用于车辆的电动马达的直流(DC)总线电压来产生用于电动马达的d轴线电流命令和用于电动马达的q轴线电流命令。一种电压命令模块被构造成基于d轴线电流命令和q轴线电流命令来产生电压命令。一种电池切换控制模块被构造成:基于电压命令确定电池的电压操作状态;当电池的多个开关断开时,在停留时间期间将电池参数与预定电压参数和预定电流参数中的至少一个相比较;以及基于该比较来产生开关控制信号以转变所述多个开关中的至少一个开关从而引起电池在电压操作状态下操作。

    A current command module is configured to, based on a direct current (DC) bus voltage for an electric motor of the vehicle, generate a d-axis current command for the electric motor and a q-axis current command for the electric motor. A voltage command module configured to generate voltage commands based on the d-axis current command and the q-axis current command. A battery switching control module is configured to: determine a voltage operating state of a battery based on the voltage commands; compare a battery parameter to at least one of a predetermined voltage parameter and a predetermined current parameter during a dwell time when a plurality of switches of the battery are open; and generate a switch control signal to transition at least one switch of the plurality of switches to cause the battery to operate in the voltage operating state based on the comparison.
