Vehicle brake control device
First Claim
1. A vehicle brake control device wherein a pair of brake operating force transmission systems are connected to a single wheel brake while enabling a brake operating force corresponding to an operating amount of a pair of brake operating members individually corresponding to the brake operating force transmission systems to be transmitted and brake operating force reducing means enabling the brake operating force transmitted to said wheel brake to be controlled in order to prevent a wheel from entering a locked state is arranged at said both brake operating force transmission systems comprising:
- a control unit for controlling an operation of said brake operating force reducing means in response to an output responsive to the wheel being in a locked state and an operating state of said brake operating force transmission systems, said control unit operates the brake operating force reducing means installed at the other of said both brake operating force transmission systems under a state just before starting an operation of the brake operating force reducing means installed at said one brake operating force transmission system when the brake operating force is transmitted only from one of both brake operating force transmission systems to said wheel brake so as to restrict the brake operating force transmission from the other brake operating force transmission system to the wheel brake, wherein said brake operating force reducing means includes a first brake operating force reducer operatively connected to a first brake operating force transmission system and a second brake operating force reducer operatively connected to a second brake operating force transmission system.

Abstract
To prevent an operational feeling from deteriorating due to an operation of the other brake operating member under a superior braking condition caused by one brake operating member in a vehicle brake control device in which a pair of brake operating force transmission systems are connected to a single wheel brake, each of brake operating force reducing means capable of weakening the brake operating force transmitted to the wheel brake is arranged at both brake operating force transmission systems. When the brake operating force is transmitted only from one of the brake operating force transmission systems TB, TC to the wheel brake BF, the brake operating force reducing means installed at the other of the brake operating force transmission systems TB, TC operates to restrict the brake operating force transmission from the other brake operating force transmission system to the wheel brake BF under a state just before starting an operation of the brake operating force reducing means installed at one brake operating force transmission system.

8. A vehicle brake control device comprising:
-
a first brake operating force transmission system for supplying a first brake operating force to a wheel brake;
a second brake operating force transmission system for supplying a second brake operating force to the wheel brake;
brake operating force reducing means operatively connected to said first and second brake operating force transmission systems for enabling the first and second brake operating forces transmitted to said wheel brake to be controlled in order to prevent a wheel from entering a locked state;
a control unit for controlling an operation of said brake operating force reducing means in response to an output responsive to the wheel being in a locked state and an operating state of said first and second brake operating force transmission systems, said control unit operates the brake operating force reducing means installed at the first brake operating force transmission system under a state just before starting an operation of the brake operating force reducing means installed at said second brake operating force transmission system when the brake operating force is transmitted only from one of the first or second brake operating force transmission systems to said wheel brake so as to restrict the brake operating force transmission from the second brake operating force transmission system to the wheel brake, wherein said brake operating force reducing means includes a first brake operating force reducer operatively connected to a first brake operating force transmission system and a second brake operating force reducer operatively connected to a second brake operating force transmission system. - View Dependent Claims (9, 10, 11, 12, 13, 14)
