Filed: 1989-07-06
Abstract: PURPOSE:To reduce the size of the device mentioned in the title by making anti-skid control valves serve as traction control valves in constitution wherein a fluid pressure braking system is switched over from a master cylinder to an accumulator when driving wheels are slipped during acceleration. CONSTITUTION:When control slip occurs, anti-skid control valves 11L, 11R, 12 control brake fluid pressure to prevent slippage of braking. When driving wheels 2L,2R are slipped during acceleration, a controller 30 turns ON a changeover valve 20 to close a system 8 and switch from a master cylinder 6 to an accumulator 21. Fluid pressure accumulated in the accumulator 21 by a pump 23 passes through a control valve 12 at OFF state, that is, at pressure increasing position to reach the driving wheels 2L,2R to control the wheels 2L,2R. When the slippage during acceleration is terminated, the changeover valve 20 is turned OFF to open the system 8 and the control valve 12 returns to pressure reducing position. Since the control valve 12 serves both as an anti-slip controller and a traction controller device, the size of the device can be compact and cost is low.
