Abstract
An electronic brake control device for a wheeled vehicle that operates in a off-road driving mode. The device including one or more inputs for receiving sensor signals to determine wheel speed, wheel retardation, and wheel acceleration, a primary control logic for modulating brake pressure during time periods under normal vehicle operating conditions, a secondary control logic for modulating brake pressure under off-road vehicle operating conditions when the off-road mode is activated, and a processing unit that calculates a vehicle reference speed and a wheel slip of each sensed and antilock brake system controlled wheel, compares the actual vehicle speed to the vehicle reference speed, and calculates at least one of a variable wheel slip threshold and a variable time period for an extended wheel slippage for controlling at least one of the individual wheel slip and the time period for an extended wheel slip.
