    • A method for determining an initiation threshold value for an automatic braking process, in which an automatic braking process is used and a brake pressure is produced which is greater than the brake pressure which corresponds to the operation of the brake pedal by the driver. Short distances between vehicles increase the risk of accidents. If a driver operates the brakes when there is a short distance between the vehicle and the preceding vehicle, in the vast majority of cases, the driver of the following vehicle is often required to perform an emergency braking due to the short distance between the vehicles. To improve the safety of vehicles, an emergency braking is performed, as quickly as possible, when the distance between vehicles is short. This emergency braking, within what is physically possible, ensures rapid deceleration of the vehicle and thus helps to avoid rear-impact accidents. While performing the automatic braking process, the method incorporates a reduction of the initiation threshold value if it is determined that the distance to a preceding vehicle is less than a predetermined limit.
    • 一种用于确定自动制动过程的起动阈值的方法,其中使用自动制动过程并产生大于由驾驶员对制动踏板的操作相应的制动压力的制动压力。 车辆之间的距离增加了事故的风险。 如果驾驶员在车辆与前一车辆之间的距离很短的情况下操作制动器,则绝大多数情况下,由于车辆之间的距离较短,以下车辆的驾驶员经常需要执行紧急制动。 为了提高车辆的安全性,当车辆之间的距离短时,尽可能快地进行紧急制动。 这种紧急制动在物理上可以确保车辆的快速减速,从而有助于避免后碰撞事故。 在执行自动制动过程时,如果确定到前一车辆的距离小于预定极限,则该方法包括起动阈值的减小。

    • The invention provides a method for determining a threshold value for triggering an automatic brake application wherein a braking pressure greater than that corresponding to the position of the brake pedal is developed when the actuating speed of the brake pedal exceeds a triggering threshold value determined from a preset threshold value and a vehicle-specific correction factor. According to the invention, a standard curve is stored representing the relationship between the vehicle deceleration and the pedal travel, said standard curve having a pedal travel value sP0 for a vehicle deceleration aFZG0=0 m/s.sup.2. During a brake application, pairs of values for pedal travel and vehicle deceleration are determined several times, with a pedal travel value sPi0 being determined for a vehicle deceleration of 0 M/s.sup.2 corresponding to each value pair, based on a curve that is the same as the standard curve. A sliding average sPm is then calculated from the values of sPi0 obtained, and the relative deviation ABW=sPm/sP0 is then determined from the value sP0 as a vehicle-specific correction factor ABW. The triggering threshold value is then determined as a function of the product of the preset threshold value VS and the vehicle-specific correction factor ABW.
    • 本发明提供了一种用于确定用于触发自动制动应用的阈值的方法,其中当制动踏板的致动速度超过从预设值确定的触发阈值时,制动压力大于对应于制动踏板位置的制动压力 阈值和车辆特定校正因子。 根据本发明,存储表示车辆减速度与踏板行程之间的关系的标准曲线,所述标准曲线对于车辆减速度aFZG0 = 0m / s2具有踏板行驶值sP0。 在制动应用期间,基于相同的曲线,确定用于踏板行程和车辆减速度的成对的值用于对应于每个值对的0M / s2的车辆减速度确定踏板行程值sPi0 作为标准曲线。 然后从所获得的sPi0的值计算滑动平均值sPm,然后从值sP0确定相对偏差ABW = sPm / sP0作为车辆特异性校正因子ABW。 触发阈值随后被确定为预设阈值VS和车辆特定校正因子ABW的乘积的函数。
