BRAKE LIQUID PRESSURE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a brake liquid pressure control device capable of suppressing a drop of the braking performance even in case any unbraked wheel is generated owing to a liquid leak at any wheel cylinder. SOLUTION: A brake liquid pressure control device includes a controller to put an accumulator 38 in communication with the wheel cylinders 48FL-48RR of car wheels when a brake 12 is to be operated and control the liquid pressures of the cylinders 48FL-48RR, wherein a sensing means senses any failed wheel to be braked, and the controller shuts off the liquid pressure supplied from the accumulator to the applicable cylinder for the failed wheel and also makes appropriate control of the liquid pressures of the other wheel cylinders.
