The invention relates to the technical field of vehicle engineering, and particularly discloses an intelligent load trailer and a control method thereof. The intelligent load trailer comprises a powermotor, a gearbox and a drive axle which are in transmission connection, a power battery supplies power to the power motor through a high-voltage distribution box and an inverter in sequence, and an intelligent control unit is connected with the inverter through a communication wiring harness; the intelligent control unit is connected with an upper computer and a test vehicle through communicationwiring harnesses, and can obtain current parameters and test parameters of the test vehicle during test on a test road section and calculate resistance to be overcome by sliding of the test vehicle under the current parameters and the test parameters; and the power motor is controlled by the inverter to output compensation torque, so that the test vehicle can simulate the target working conditionunder the test parameters under the current working condition, a test site and a load do not need to be independently set, and the application range is wide.

    本发明涉及车辆工程技术领域,具体公开了一种智能负荷拖车及其控制方法,该智能负荷拖车包括传动连接的动力电机、变速箱和驱动桥,动力电池依次通过高压配电箱和逆变器给动力电机供电,智能控制单元与逆变器通过通讯线束连接,且智能控制单元通过通讯线束与上位机及测试车辆相连接,智能控制单元能获取测试车辆于测试路段测试时的当前参数和测试参数,并计算测试车辆在当前参数和测试参数下滑行所需克服的阻力,并通过逆变器控制动力电机输出补偿扭矩,以使测试车辆可在当前工况下模拟测试参数下的目标工况,无需单独设置测试场地和负载,适用范围广泛。
