  • Wheel understeer speed control
    Patent number: 5258912
    Abstract: An apparatus provides improved vehicle handling during turning maneuvers by providing control of vehicle understeer. The understeer control includes determining a desired turning radius for the vehicle, a corresponding ideal outer to inner wheel speed ratio. A closed loop torque command is determined in proportion to the difference between the ideal wheel speed ratio and the actual wheel speed ratio. The closed loop torque command is used in conjunction with an open loop torque command responsive to operator power demand to provide wheel speed control in a manner to maintain the desired vehicle understeer characteristics.
