    • An anti-lock braking method to retard the wheels of a vehicle provides thatbrake pressure be augmented or reduced or maintained constant in response to slip and/or the change in the rotational speed (positive or negative deceleration) of a retarded wheel as related to at least one threshold value, andthe respective renewed accelerations of the retarded wheels be measured during successive control cycles of the anti-lock braking so as to raise the threshold value or prevent a reduction of the brake pressure for a predetermined period of time in order to suppress undesired control operations which are releasable above all by oscillations of the vehicle axle. To avoid interference of the ABS control by axle oscillations, it is provided thata raised threshold value is maintained for a given period of time and then lowered once more to the basic value if no wheel retardation is measured and the threshold value is not exceeded either during this given period of time, the given period of time being somewhat longer than one axle oscillation period of a vehicle axle, whereasin the event that the threshold value is failed to be reached within the given period of time, this will not initiate a reduction of the brake pressure of the wheel, and a period of time will be measured during which the threshold value remains to be fallen short of, andin the event that this measured period of time is shorter than a predetermined period of time, reduction of the brake pressure continues to be precluded for an additional period of time which is at least as long as one typical axle oscillation period of the vehicle axle.
    • 用于延迟车辆的车轮的防抱死制动方法提供了制动压力响应于延迟轮的滑动和/或转速(正或负减速度)的变化而增大或减小或保持恒定,与 至少一个阈值,并且在防抱死制动的连续控制循环期间测量延迟轮的相应的更新的加速度,以便提高阈值或者防止制动压力降低预定时间段 以抑制首先通过车辆轴的振荡而可释放的不期望的控制操作。 为了避免ABS控制通过轴振动的干扰,提供了在给定时间段内保持升高的阈值,然后如果没有测量车轮延迟并且不超过阈值,则再次降低到基本值 在给定的时间段内,给定的时间段比车轴的一个轴振荡周期稍长,而在给定的时间段内不能达到阈值的情况下,这不会启动 将测量车轮的制动压力的降低和一段时间,在此期间阈值将保持不足,并且在该测量的时间段短于预定时间段的情况下,减少 制动压力继续被排除了至少与车轴的一个典型轴振荡周期一样长的时间段。
