Brake control method and brake control apparatus for motorcycle
First Claim
1. In a brake control method for a motorcycle which includes a front master cylinder, front wheel cylinder means hydraulically connected to said front master cylinder, a rear master cylinder, a rear wheel cylinder hydraulically connected to said rear master cylinder and a hydraulic pressure pump which sucks the brake fluid from said rear master cylinder and supplies discharging pressure fluid to said rear wheel cylinder, the improvement comprising:
- supplying brake pressure fluid only to said front wheel cylinder means from said front master cylinder and thereby driving said hydraulic pressure pump to supply discharging pressure fluid to said rear wheel cylinder when only said front master cylinder is operated, and supplying brake pressure fluid only to said rear wheel cylinder from said rear master cylinder and discharging no brake fluid from said front master cylinder when only said rear master cylinder is operated.

Abstract
In a brake control method for a motorcycle which includes a front master cylinder, front wheel cylinders hydraulically connected to the front master cylinder, a rear master cylinder, a rear wheel cylinder hydraulically connected to the rear master cylinder and a hydraulic pressure pump. When only the front master cylinder is operated, brake pressure fluid is supplied to the front wheel cylinders and the fluid pressure pump is driven to supply discharging pressure fluid to the rear wheel cylinder, and when only the rear master cylinder is operated, brake pressure fluid is supplied only to the rear wheel cylinder.

11. In a brake control apparatus for a motorcycle which includes:
-
a first electro-magnetic changeover valve apparatus arranged between a front master cylinder, supplying brake fluid only to front wheel cylinder means, and said front wheel cylinder means;
a second electro-magnetic changeover valve apparatus arranged between a rear master cylinder and a rear wheel cylinder;
a hydraulic pressure pump which is connected for sucking the brake fluid from said rear master cylinder and is not connected to suck the brake fluid from said front master cylinder;
a first association electro-magnetic changeover valve arranged between said rear master cylinder and said rear wheel cylinder, said first association electro-magnetic changeover valve having a normally communicating state; and
a second association electro-magnetic changeover valve connected at one side between said rear master cylinder and said first association electro-magnetic changeover valve and connected at another side thereof to an inlet port side of said hydraulic pressure pump, said second association electro-magnetic changeover valve having a normally cutout state whereby when said front master cylinder is operated, said first association electro-magnetic changeover valve and second association electro-magnetic changeover valve are changed over from a communicating state to a cutout state and from a cutout state to a communicating state respectively, and said hydraulic pressure pump is driven to suck the brake fluid from said rear master cylinder through said second association electro-magnetic changeover valve and to supply discharging pressure fluid to said rear wheel cylinder.

12. In a brake control apparatus for a motorcycle which includes:
-
a first electro-magnetic changeover valve apparatus arranged between a front master cylinder, supplying brake fluid only to a first front wheel cylinder and said first front wheel cylinder;
a second electro-magnetic changeover valve apparatus arranged between a rear master cylinder and a rear wheel cylinder;
a hydraulic pressure pump which is connected to suck the brake fluid from said rear master cylinder and does not suck the brake fluid from said front master cylinder;
a third electro-magnetic changeover valve apparatus arranged between said rear master cylinder and a second front wheel cylinder different from said one front wheel cylinder, said third electro-magnetic changeover valve apparatus normally communicating said second front wheel cylinder with said rear master cylinder;
a first association electro-magnetic changeover valve arranged between said rear master cylinder and said rear wheel cylinder, said first association electro-magnetic changeover valve having a normally communicating state; and
a second association electro-magnetic changeover valve connected at one side between said rear master cylinder and said first association electro-magnetic changeover valve and connected at another side thereof to an inlet port side of said hydraulic pressure pump, said second association electro-magnetic changeover valve having a normally cutout state, whereby when said front master cylinder is operated, said first association electro-magnetic changeover valve and second association electro-magnetic changeover valve are changed over from a communicating state to a cutout state and from a cutout state to a communicating state respectively, and said hydraulic pressure pump is driven to suck the brake fluid from said rear master cylinder through said second association electro-magnetic changeover valve and to supply discharging pressure fluid to said rear wheel cylinder. - View Dependent Claims (13, 14, 15, 16, 17)
