  • Patent number: 5311433
    Abstract: A device for controlling the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at a level which ensures a good acceleration and straight line running stability. The device determines a target speed of the rotation of the driving wheels, and controls a drive torque of the driving wheels in such a manner that the actual speed of the rotation of the driving wheels coincides with the target speed. Also, the device detects a friction coefficient between the driving wheels and the road surface, and the slippage of the driving wheels is controlled on the basis of the friction coefficient. Further, the device determines the reliability of the detected friction coefficient, and uses the detected friction coefficient only when the detected friction coefficient is determined to be reliable.

  • Patent number: 5248010
    Abstract: An acceleration slip control device for a vehicle, by which the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at level ensuring a good acceleration and straight line running stability. The device controls the slippage of the driving wheel by adjusting a drive torque according to the amount of a deviation of the actual speed of rotation of the driving wheels from a target speed of the driving wheels. The drive torque is controlled in such a manner that the rate of change of the drive torque includes a component proportional to the rate of change of the slippage of the driving wheels and the proportional factor is selected in such a manner that the proportional factor is larger when the component acts to increase the drive torque and is smaller when the component acts to decrease the drive torque.
