Title: (EN) Control device for four-wheel drive electric vehicle
(ZH) 四轮驱动电动车辆的控制装置
Abstract: front page image
(EN) The purpose of the present invention is to prevent shock from occurring due to the intervention of regenerative control while operating in the four-wheel drive state. The power source has a motor/generator (4), and an electronically controlled coupling (42) is provided on the drive power transmission path leading from the power source to the front and rear wheels. This FF base four-wheel drive hybrid vehicle is provided with a 4WD control unit (85) that outputs to the electronically controlled coupling (42) a transmission torque command value to bring about the four-wheel drive state, in accordance with the vehicle state. The 4WD control unit (85) has a regenerative control intervention-coordinating controller that, when regenerative control by the motor/generator (4) has intervened during the four-wheel drive state, brings the transmission torque of the electronically controlled coupling (42) to zero before initiating regenerative control.
(ZH)

防止在四轮驱动状态时因再生控制介入而产生震动。在驱动源中具有电动发电机(4),在从驱动源向前后轮的驱动力传递路径中设置有电子控制耦合器(42)。在该FF型的四轮驱动混合动力车辆中,具备向电子控制耦合器(42)输出根据车辆状态设为四轮驱动状态的传递扭矩指令值的4WD控制部件(85)。4WD控制部件(85)具有再生控制介入协调控制部,在四轮驱动状态下电动发电机(4)的再生控制介入时,该再生控制介入协调控制部在再生控制开始之前使电子控制耦合器(42)的传递扭矩为零。
