Antiskid control device

Claim 1

An antiskid control device (1) for a motor vehi­cle, including a first detection means (14) for outputting, upon detection that an acceleration (Vd) of each of wheels of the motor vehicle has dropped below a first acceleration reference value (α1) into a deceleration region, a first signal indicative of the detection of said first detection means (11), said antiskid control device (1), when the first signal has been outputted by said first detection means (14), deciding that the wheels trend towards locking and performing a braking pressure adjusting operation of adjust­ing a braking pressure for the purpose of preventing rise of the braking pressure, said antiskid control device (1) comprising: a second detection means (15) which outputs, upon detection that the acceleration (Vd) has exceeded a second acceleration reference value (α2) different from the first acceleration reference value (α1) into an acceleration region during a first predetermined time interval (T1) after the first signal was outputted by said first detection means (14), a second signal indicative of the detection of said second detection means (15); a timer means (24) which starts counting of a second predetermined time interval (T2) at the moment when the second signal has been outputted by said second detec­tion means (15); a third detection means (16) which outputs, upon detection that the acceleration (Vd) has dropped below a third acceleration reference value (α3) different from the first and second acceleration reference values (α1, α2) into the deceleration region, a third signal indicative of the detection of said third detection means (16); and a restriction means (28) which causes the braking pressure adjusting operation to be performed only while the third signal is being outputted by said third detection means (16) during actuation of said timer means (24).
