Braking device for use in vehicle

An anti-skid braking device for use in a vehicle, comprising:

• first means for supplying a braking force to a wheel of the vehicle;
• second means for detecting an angular acceleration of said wheel to thereby deliver an acceleration signal representing an angular acceleration of said wheel;
• third means, connected to said second means, for generating a first signal when said acceleration signal received from said second means has a value that corresponds to a predetermined negative angular acceleration value during supply of the braking force to the wheel by said first means, and for generating a second signal when said acceleration signal from said second means has a value higher than said predetermined negative angular acceleration;
• fourth means, connected to said third means, for measuring a reference time interval which corresponds to a duration between a first time at which the fourth means receives said first signal from said third means, and a second time at which said fourth means receives said second signal from said third means, for obtaining another time interval by multiplying said reference time interval by a predetermined coefficient and for delivering a third signal after an elapse of said another time interval from an occurrence of said second signal;
• and
• fifth means, connected to said third and fourth means, for receiving said first and third signals, and connected to said first means for moderating the braking force for a moderation time interval between a reception time of said first signal and that of said third signal;
• said predetermined coefficient being so predetermined that with respect to an actual frictional coefficient at a commencement time of a preceding moderation time interval, an actual frictional coefficient at a commencement time of a moderation time interval subsequent to said preceding moderation time interval approaches a maximum value of an actual frictional coefficient in one anti-skid operation of said device.
