Abstract
A system for controlling at least one of the slip threshold and the time period for an extended wheel slippage for a vehicle that is operating in the off-road ABS mode. When driving in a curve pattern and/or at high speeds, the individual wheel speeds are controlled with a lower slip threshold and/or shorter time period for the extended wheel slippage than when driving straight ahead and/or at a lower vehicle speed. Control of the brakes is accomplished by (i) controlling at least one of the individual wheel slip threshold and the time period for an extended wheel slippage based on the actual vehicle speed; (ii) controlling at least one of the individual wheel slip threshold and the time period for an extended wheel slippage depending on actual lateral acceleration; (iii) using a lateral acceleration sensor to measure actual lateral acceleration; (iv) measuring the actual steering angle with a sensor and controlling the wheel speed cycles in conjunction with the actual vehicle speed; (v) using a yaw rate sensor to determine at least one of the deepness and the time period of the wheel slippage; (vi) controlling the speed of the wheels on either side of the vehicle with different sl…
