The invention relates to a motorized driveline with a centralized power distribution strategy and decentralized inverters. A method for distributing electric power to an electric motor in an electric powertrain system, where the electric motor is electrically connected to a shared power source, includes receiving an input signal via a supervisory controller. The input signals include a total torque request for the electric powertrain and a power limit for the power source. The method includes determining an open-loop torque command for each respective motor in response to the input signal. In response to the total torque request and the power supply limit, the controller also determines maximum and minimum power limits for the motor, where the maximum and minimum power limits include calibrated power retention for performing the predetermined torque operation. The method includes transmitting an open-loop torque command and a power limit to a respective motor control processor of each motor to control torque operation.

    本发明涉及具有集中式功率分配策略和分散式逆变器的电动化传动系统。一种用于向电动动力系统中的电动马达分配电力的方法,其中电动马达电连接到共享电源,该方法包括经由监管控制器接收输入信号。输入信号包括电动动力系统的总扭矩请求和电源的电力限制。该方法包括响应于输入信号针对每个相应的马达确定开环扭矩命令。响应于总扭矩请求和电源限制,控制器还确定马达的最大和最小功率限制,其中最大和最小功率限制包括用于执行预定扭矩操作的经校准的功率保留。该方法包括将开环扭矩命令和功率限制传输到每个马达的相应马达控制处理器,从而控制扭矩操作。
