Document Type and Number:
Japanese Patent JPH02503178
Kind Code:
A
Abstract:
PCT No. PCT/EP88/00130 Sec. 371 Date Sep. 22, 1989 Sec. 102(e) Date Sep. 22, 1989 PCT Filed Feb. 23, 1988 PCT Pub. No. WO88/07466 PCT Pub. Date Oct. 6, 1988.An anti-skid brake control system for a motor vehicle includes at least one sensor for determining the deceleration VR of a vehicle wheel, a device for determining the deceleration VF of the vehicle, a device for determining the difference D of the vehicle and wheel decelerations (D=VF-VR), a control circuit responsive to the difference D for producing brake pressure control signals, and a brake pressure control device for increasing and decreasing the given brake pressure in response to the control signals from the control circuit. The difference D is also supplied to a ladder filter. During phases in which brake pressure is maintained at a constant level, the ladder filter is switched to identification by the control circuit and determines a reflection coefficient. The control signals then affect the brake pressure so as to select a slippage value on a stable branch of the mu slippage curve and near its maximum is derived from the distance of the reflection coefficient from the value "1".
