Patent ID: 8210619

Claim:
A braking control system of a two-wheeled motor vehicle, comprising: a first braking operation unit, a first-wheel brake to be actuated by the first braking operation unit, a first-wheel hydraulic circuit transmitting operation of the first braking operation unit to the first-wheel brake, a second braking operation unit, a second-wheel brake to be actuated by the second braking operation unit, a second-wheel hydraulic circuit transmitting operation of the second braking operation unit to the second-wheel brake, and a control unit for performing both-wheel-interlocked braking control that allows the first-wheel brake and the second-wheel brake to operate in an interlocked manner, the first-wheel brake including a first-wheel interlocked brake that operates according to the both-wheel-interlocked braking control, and a first-wheel non-interlocked brake that does not operate according to the both-wheel-interlocked braking control, wherein the first-wheel hydraulic circuit comprises a first-wheel-side master cylinder connected to the first braking operation unit, a first-wheel-side switching valve connected to the first-wheel-side master cylinder, a first-wheel-side first inlet valve that is connected to the first-wheel-side switching valve at one end, and is connected to the first-wheel interlocked brake at the other end, a first-wheel-side second inlet valve that is connected to the first-wheel-side master cylinder at one end, and connected to the first-wheel non-interlocked brake at the other end, a first-wheel-side intake valve that is connected to the first-wheel-side master cylinder at one end, wherein the braking control system comprises a normal-brake-operable condition and an active pressure increase condition of the first wheel brake with the braking control system being shifted to both-wheel-interlocked braking mode, wherein under an active pressure increase condition of the first wheel brake, the control unit controls such that the first-wheel-side intake valve is opened, the first-wheel-side switching valve is closed, and the first-wheel-side first inlet valve is opened, whereby the first-wheel interlocked brake is increased in pressure and thus used for the both-wheel-interlocked braking control in a manner of being interlocked with the second-wheel brake, and the control unit keeps the first-wheel-side second inlet valve to be opened such that the first-wheel non-interlocked brake receives hydraulic pressure caused along with operation of the first braking operation unit during the pressure increase.
