  • Brake control system
    Patent number: 6325469
    Abstract: A brake system control for use in a vehicle with four wheels comprising the steps of: determining a desired yaw rate (454); determining a yaw torque command responsive to the desired yaw rate (806); if the vehicle is in an anti-lock braking mode during driver commanded braking, applying the yaw torque command to only one of the four wheels to release brake pressure in said one of the four wheels (258-266, 274, 278, 280, 410-418); if the vehicle is in a positive acceleration traction control mode during driver commanded acceleration, applying the yaw torque command to only one of the four wheels to apply brake pressure in said one of the four wheels (258-266, 288-292, 410-418); and if the vehicle is not in the anti-lock braking mode or in the positive acceleration traction control mode, then: (i) determining whether a vehicle brake pedal is depressed (370); (ii) if the vehicle brake pedal is depressed, applying brake force to the vehicle wheels responsive to the depression of the brake pedal (374, 412, 418), w

  • Brake control system
    Patent number: 6212460
    Abstract: In a vehicle with an active brake control system a control method comprising to the steps of: determining individual wheel speeds of the vehicle wheels responsive to sensor output signals (1016, 1018); determining a vehicle reference velocity responsive to the individual wheel speeds (1002-1012); measuring vehicle yaw rate (1128); determining a delta velocity for each wheel responsive to the individual wheel speed for the wheel and the vehicle reference velocity (326); and when the active brake control system is in the active state for at least one of the wheels, (a) setting a base delta velocity for the one wheel equal to the delta velocity for the one wheel immediately prior to the active brake control obtaining the active state for the one wheel (200); (b) determining a control term responsive to the measured vehicle yaw rate (806), wherein the control term represents a desired delta velocity for the one wheel; (c) setting a first target change in delta velocity responsive to the base delta velocity and th
