    • A torque distribution control device for a four-wheel drive vehicle is disclosed having a torque distribution device for distributing the drive power transmitted from an engine to either of the front wheels or the rear wheels as prime drive wheels, to other wheels as sub-drive wheels. In the control device, a pre-torque is determined in a feed forward sense based on the vehicle speed, the throttle opening degree and the gear shift step of a transmission. A compensation torque is determined in a feedback sense based on the vehicle speed and the rotational speed difference between the drive wheels and the sub-drive wheels. A torque transmission clutch is controlled based on a command torque which is obtained by the addition of the pre-torque and th compensation torque, so that the command torque is distributed to the sub-drive wheels. In the control device of another embodiment, a pre-torque is determined in a feed forward sense based on the vehicle speed and the throttle opening degree. The pre-torque is compensated based on the throttle opening degree and the acceleration/deceleration of the vehicle. A feedback torque is determined in a feedback sense based on the rotational speed difference between the drive wheels and the sub-drive wheels and the vehicle speed. The pre-torque and the compensation torque are added for a command torque, and a torque transmission clutch is controlled based on the command torque to distribute the same to the sub-drive wheels.
    • 公开了一种用于四轮驱动车辆的扭矩分配控制装置,其具有扭矩分配装置,用于将从发动机传递的任一个作为主驱动轮的前轮或后轮的驱动力分配给作为副驱动器的其他车轮 车轮。 在控制装置中,基于变速器的车速,节气门开度和变速档位,在前馈方向上确定预转矩。 基于车速和驱动轮和副驱动轮之间的转速差,在反馈意义上确定补偿扭矩。 基于通过增加预转矩和第二补偿转矩而获得的指令转矩来控制转矩传递离合器,从而将指令转矩分配给副驱动轮。 在另一实施例的控制装置中,基于车速和节气门开度,以前馈方向确定预转矩。 基于车辆的节气门开度和加速/减速来补偿预转矩。 基于驱动轮和副驱动轮之间的转速差和车速,在反馈意义上确定反馈转矩。 增加预转矩和补偿扭矩作为指令转矩,根据指令转矩控制转矩传递离合器,将其分配到副驱动轮。

    • A driving force control unit for a vehicle, which allows transmission of driving force from a driving motor to driving wheels irrespective of releasing an accelerator pedal at a certain or lower vehicle speed when a transmission is selected to a running range, and which switches the magnitude of the driving force while the accelerator pedal is released at a vehicle speed no more than the certain vehicle speed between a greater condition and a smaller condition in accordance with depression of a brake pedal so that the driving force is made lower at a depression of the brake pedal than at a release of the brake pedal, wherein the driving force value in the greater condition at a certain or lower vehicle speed is changed according to the vehicle speed, and the change of the driving force value is characterized in that the driving force value becomes smaller as reaching from the vehicle speed at the maximum driving force value to the certain vehicle speed, and further switching the driving force, before stopping the vehicle, from the greater condition to the smaller condition is permitted merely in the vicinity of the certain vehicle speed.
    • 一种用于车辆的驱动力控制单元,其允许当将变速器选择为行驶范围时将来自驱动电动机的驱动力传递到驱动轮,而不管以一定或更低车速释放加速器踏板,并且其转换幅度 的驱动力,同时根据制动踏板的下压,在不同于较大条件和较小状态之间的车速下,车速不大于某一车速,使得驱动力在下降 制动踏板比在制动踏板的释放时更大,其中在一定或更低的车速下的较大条件下的驱动力值根据车速而改变,并且驱动力值的变化的特征在于驱动力 值从最大驱动力值下的车速达到某一车速时变小,进一步切换 只有在某一车辆速度附近才允许在停止车辆之前,从更大的状态到更小的状态。
