    • A driving force control system for a four-wheel drive vehicle is disclosed which enables the vehicle to smoothly start on a low-null road surface, and is capable to distributing just required amounts of driving forces to auxiliary drive wheels depending on an actual accelerating condition of the vehicle, thereby improving the response and fuel economy of the vehicle. The four-wheel drive vehicle includes front wheels as main drive wheels, and rear wheels as auxiliary drive wheels. The driving force control system controls engagement forces of electromagnetic clutches to thereby control the driving forces (torques) distributed to the rear wheels. The 2/4WDnullECU of the driving force control system calculates a filtered vehicle acceleration XGF1F of the vehicle 2 based on a drive torque TD, and then calculates a basic VATC torque value VATC based on the calculated filtered vehicle acceleration XGF1F, for use in calculation of the final desired VATC torque value TOBJM of torque to be distributed to the rear wheels.
    • 公开了一种用于四轮驱动车辆的驱动力控制系统,其使得车辆能够在低mu路面平稳地启动,并且能够根据实际加速条件将恰好所需量的驱动力分配到辅助驱动轮 的车辆,从而提高车辆的响应和燃料经济性。 四轮驱动车辆包括作为主驱动轮的前轮和作为辅助驱动轮的后轮。 驱动力控制系统控制电磁离合器的接合力,从而控制分配到后轮的驱动力(转矩)。 驱动力控制系统的2 / 4WD.ECU基于驱动转矩TD计算车辆2的过滤车辆加速度XGF1F,然后基于计算出的过滤车辆加速度XGF1F计算基本的VATC转矩值VATC,以用于 计算要分配给后轮的扭矩的最终所需的VATC扭矩值TOBJM。
