发明名称 Method of limiting braking pressure on a vehicle brake.
摘要 <p>In an anti-lock braking system, when wheel parameters including slip represent an incipient wheel lock-up condition normally calling for a release of brake pressure during a pressure apply mode of an anti-lock braking cycle and the duration of the pressure apply mode is less than a predetermined threshold representing an abnormal rapid cycling of the brake pressure, the wheel slip threshold Sthreshold representing an incipient wheel lock-up condition is increased, the rate of increase in brake pressure during the brake pressure apply mode is set to a high level and the pressure apply mode is continued during which the wheel brake pressure is ramped at the increased rate. These steps are repeated while the wheel parameters represent an incipient wheel lock-up condition normally calling for a release of brake pressure until the time of the pressure apply mode equals the predetermined threshold representing a normal brake pressure cycling period. At this time, the rate of pressure increase during the apply mode is returned to normal and the system is set to a release mode wherein the brake pressure is released. The slip threshold Sthreshold is thereby adjusted to establish normal brake pressure cycling. &lt;IMAGE&gt;</p>
