摘要： An anti-skid brake control system comprises a limiter which provides an upper limit of variation of wheel speed indicative data. The limited wheel speed indicative data is derived with respect to each wheel. The greatest limited wheel speed indicative data is selected as vehicle body speed indicative initial data. The anti-skid brake control system derives a projected vehicle body speed indicative data by adding an integrated value of a longitudinal acceleration to the aforementioned vehicle body speed indicative initial data. The integrated value is provided with a predetermined offset value for compensating for error caused in a longitudinal acceleration sensor.

摘要： In an antiskid braking system for increasing or decreasing a braking force according to a wheel speed and a vehicle speed, an algorithm applied to the determination of a braking force decrease amount is improved. Once a target braking force decrease amount is determined according to the wheel speed and vehicle speed, this is compared with a predetermined minimum decrease amount, and when the target decrease amount is less than the minimum decrease amount, braking force is decreased according to the minimum decrease amount. The minimum decrease amount is preferably determined according to the braking force immediately before the braking force decrease. In this way, braking force reduction insufficiencies in several conditions are prevented.

摘要： In an antiskid brake system that increases or decreases a wheel cylinder pressure according to a wheel speed and vehicle speed, an algorithm applied to pressure increase after pressure decrease is improved. A first target pressure increase amount is computed based on the wheel speed and vehicle speed, and a second target pressure increase amount is computed based on a total pressure decrease amount when pressure is decreased. The wheel cylinder pressure is then increased according to the first target pressure increase amount when an elapsed time from the start of pressure decrease to the start of pressure increase, is longer than a predetermined value, and according to the second target pressure increase amount when the elapsed time is shorter than the predetermined value. In this way, increase of slip amount due to excessive pressure increase is prevented.

摘要： A system for correcting a wheel speed data produced by a wheel speed sensor, employs a filter for removing noise contained in the output of the wheel speed sensor. The filter limits variation rate of the wheel speed data so as to avoid occurrence of extraordinary variation of wheel speed as influenced by error factors, such as destruction of the wheel speed sensor or noise superimposed on the output of the wheel speed sensor.

摘要： An anti-skid brake control system two mutually different mode for projecting the vehicle body speed representative data. In the first mode, the vehicle body speed representative data is derived on the basis of an instantaneous wheel speed data which is latched upon initiation of vehicular braking operation or upon detection of vehicular braking deceleration, and an integrated value of a longitudinal acceleration indicative signal. On the other hand, in a second mode, the vehicle body speed representative data is derived on the basis of the initially latched instantaneous wheel speed data and a fixed value of wheel deceleration gradient data. A first vehicle body speed representative data derived through the first mode of operation and a second vehicle body speed representative data derived through the second mode of operation are selectively used as the vehicle body speed representative data.
