Abstract

PURPOSE:To prevent the braking distance from being increased at the time of slow braking by detecting the operating state of a brake pedal to discriminate the fast and slow motion, and delaying the start time of anti-lock control in case of slow braking as compared with the fast braking. CONSTITUTION:An anti-lock control device 70 takes in signals of rear wheel, left front wheel, right front wheel speed sensors 84, 88, 89 and a brake switch 92 and when it is judged that lock in wheels is caused by braking operation for deceleration, the control device controls liquid pressure to right and left front wheel cylinders by solenoid hydraulic control valves 18, 18 and a solenoid switching valve 58 of its by-pass and liquid pressure to a rear wheel cylinder by a solenoid hydraulic control valve 24 to conduct anti-lock control. In this case, the brake pedal operating speed is detected from a signal of a potentiometer 68 to judge the fast and slow motion. In case of slow braking, the start time of anti-lock control is delayed more than in case of fast braking. Thus, it is possible to overcome the disadvantage of the braking distance being increased due to anti-lock control at the time of slow braking.
