摘要： A method of operating a vehicle braking system that includes a braking devices each of which is configured to apply brake torque to a wheel at either end of an axle of the vehicle. The method comprises receiving one or more electrical signals indicative of a brake command. The method further comprises obtaining a value of each of one or more vehicle-related parameters as brake torque is applied to the wheels at either end of the axle by the braking devices in response to the brake command, and detecting a brake-pull on the vehicle based on the obtained value(s) of the one or more vehicle-related parameters. The method still further comprises automatically adjusting an amount of brake torque being produced by at least one of the braking devices to equalize the amount of brake torque being applied across the axle, thereby mitigating the detected brake-pull.

摘要： A method and system are provided for modifying anti-lock brake control to a vehicle braking on a surface having a split-mu to higher-mu transition. The time duration of the apply stage of an anti-lock brake system cycle is measured for the two front wheels. The measured apply stage durations are compared to a selected threshold. The transition from the split-mu surface to the higher-mu surface is detected when the apply stage duration for the lower-mu wheel exceeds the selected threshold. An increased brake pressure rate is applied to both front wheels when the split-mu to high-mu transition is detected.

摘要： A two or more channel electronic braking system (EBS) adapted to control at least one axle by a single control channel and wherein wheel speed signals (W1, W2, W3, W4), from at least four vehicle wheels are processed in an electronic controller. Wheel speed input processors provide accurate wheel speed measurements which are updated frequently and regularly and further processed to yield wheel and vehicle deceleration signals and a rate of change of deceleration signal. When speed selectors (90) are switched by a mode control section (50) to "Select Low" or "Select High" when split mu conditions are detected. The mode control section (50) accepts processed slip averages and skid control conditions to detect split-adhesion operation and make thereupon the "Select High" or "Select Low" decisions. The latter components collectively give ABS operation characterised by having the vehicle operating mode set to "Select Low" until split-adhesion conditions are detected on any axle when on the first skid cycle where any processed and filtered wheel-slip level is large, whilst at the same time the processed slip levels at the opposite wheel on that axle and at the wheel on the opposite end of a second axle are both low and the deceleration of the vehicle does not exceed a mid range value pre-set in the band 2.5 to 3.5 m/s .

摘要： A method and system for modifying anti-lock brake control to a vehicle braking on a surface having a low-mu to split-mu transition. The time duration of the apply stage of an anti-lock brake system cycle is measured for the two front wheels. The measured apply stage durations are compared to a threshold. The braking coefficients of the two front wheels are qualified based on these comparisons. Each wheel is qualified as normal-duration if the apply stage duration is less than the threshold, and long-duration if the apply stage duration is greater than the threshold. Normal low-mu pressure control is continued if both front wheels are qualified as normal-duration. Split-mu pressure control is activated when exactly one of the front wheels is qualified as long-duration. The split-mu pressure control restricts the rate of brake pressure applied to the long-duration wheel. Low-mu to high-mu pressure control is utilized when both wheels are qualified as long-duration.
摘要翻译：一种用于将防抱死制动控制改变为在具有低μ到分裂mu转变的表面上的车辆制动的方法和系统。测量两个前轮的防抱死制动系统循环的施加阶段的持续时间。将测量的应用阶段持续时间与阈值进行比较。基于这些比较，两个前轮的制动系数合格。如果应用阶段持续时间小于阈值，则每个轮子都被认定为正常持续时间，如果应用阶段持续时间大于阈值，则其持续时间长。如果两个前轮被认定为正常持续时间，则继续正常的低压力控制。当正确的前轮之一被认定为长持续时间时，分体式压力控制被激活。 split-mu压力控制限制施加到长时间轮的制动压力的速率。当两个车轮被认定为长持续时间时，利用低mu至高mu压力控制。
