  • Patent number: 11535106
    Abstract: A power supply system includes power circuit which connects first and second batteries with a drive motor, and a management ECU which controls transfer of power between the batteries and the drive motor. The management ECU limits the output power of the second battery to no more than a second output upper limit, during combined output travel which drives the drive motor by way of the combined output of the first and second batteries. In addition, the management ECU sets the second output upper limit to a second maximum output of the second battery in the case of the first SOC of the first batter being greater than a remaining amount warning threshold, and sets the second output upper limit to a range extending upper limit which is smaller than the second maximum output, in the case of the first SOC being less than the remaining amount warning threshold.

  • Patent number: 6076033
    Abstract: A process for controlling a yaw moment in a vehicle by generating a braking force in one of the left and right wheels of the vehicle and by generating a driving force in the other wheel. When a vehicle is accelerated during the turning thereof, grounding loads of rear wheels are increased in order to generate a yaw moment in a direction opposite from a turning direction. However, such yaw moment can be eliminated in order to enhance the turning performance by bringing one of the hydraulic clutches into an engaged state with a torque which is proportional to a product of longitudinal and lateral accelerations. Consequently, a braking force and a driving force in inner and outer wheels during turning of the vehicle, respectively, are generated. When the vehicle is decelerated during turning thereof, grounding loads of front wheels are increased to a yaw moment in the same direction as the turning direction.

  • Patent number: 5752575
    Abstract: A gearbox and two hydraulic clutches are disposed between left and right follower wheels of a vehicle. The torque transfer capacity of the hydraulic clutches is controlled to effect the distribution of a torque between the follower wheels. In a low lateral acceleration range, the torque transfer capacity is increased in accordance with an increase in lateral acceleration to enhance the turning performance and the high-speed stability performance. In a high lateral acceleration range, the torque transfer capacity is decreased in accordance with an increase in lateral acceleration, such that it does not exceed a largest frictional force of a wheel acting as an inner wheel during turning movement of the vehicle, thereby insuring a cornering force.
