The invention relates to a commercial vehicle power generation device based on a BSG motor and a control method of the commercial vehicle power generation device. The power generation device comprises a BSG motor, a pre-charging DCDC, a loading battery pack, a battery management module, a power generation device controller and a relay. A driving end of the BSG motor is connected with an engine of a commercial vehicle, a bus of the BSG motor is connected with a power supply end of the battery management module through a contact of the relay, an output end of the pre-charging DCDC is connected with the bus of the BSG motor, the power supply end of the battery management module is connected with loading equipment, and the power generation device controller controls operation of all the equipment; the control method comprises the following steps: firstly, judging whether the commercial vehicle is in a driving or parking state and whether the loading battery pack is allowed to be charged; then, responding power generation torque requests of the BSG motor during parking and driving according to conditions; and finally monitoring the charging of the BSG motor. The power generation efficiency and the reliability of the whole vehicle are improved, and the vehicle performance and emission in the power generation process are optimized and improved.

    本发明涉及一种基于BSG电机的商用车发电装置及其控制方法;该发电装置含有BSG电机、预充DCDC、上装电池组、电池管理模块、发电装置控制器和继电器;BSG电机的驱动端与商用车的发动机连接,BSG电机的母线通过继电器的触点与电池管理模块的电源端连接,预充DCDC的输出端与BSG电机的母线连接,电池管理模块的电源端与上装设备连接,发电装置控制器控制各设备的运行;该控制方法先判断商用车是否处于行车或驻车状态,以及上装电池组是否允许充电;然后分情况进行驻车和行车时BSG电机的发电扭矩请求;最后监控BSG电机的充电。本发明提高了发电效率和整车的可靠性,且优化和改善了发电过程中的车辆性能和排放。
