1. A braking control apparatus for vehicles, which controls braking forces exerted on front and rear wheels of a vehicle respectively, the apparatus comprising:
- vehicle speed determining means for determining a speed v of the vehicle;
deceleration determining means for determining a deceleration d of the vehicle; and
braking control means for determining a predetermined value f(v) that is a function value determined according to said speed v of the vehicle and said predetermined value f(v) becomes smaller with increase in said speed v, the braking control means performing such control that when the deceleration d is not less than the predetermined value f(v), the braking force exerted on the rear wheels is less than the braking force exerted on the front wheels, and when the deceleration d is less than said predetermined value f(v), the braking force exerted on the rear wheel is increased.

Abstract
A braking control apparatus for vehicles is provided with a braking control for performing such control that when deceleration d determined by a deceleration determining device is not less than a predetermined value f(v) according to vehicle speed v determined by a vehicle speed determining device, a braking force exerted on a rear wheel is limited as compared with a braking force exerted on a front wheel. This predetermined value f(v) is set so as to become smaller with increase in the vehicle speed v.

7. A braking control apparatus for vehicles, which controls braking forces exerted on front and rear wheels of a vehicle respectively, the apparatus comprising:
-
a vehicle speed sensor for measuring a speed v of the vehicle; and
a braking control unit which determines a predetermined value f(v) that is a function value determined according to said speed v of the vehicle and said predetermined value f(v) becomes smaller with increase in said speed v, the braking control unit determines a deceleration d of the vehicle based on said speed v measured by said vehicle speed sensor and controls the braking force applied to each wheel so that when the deceleration d is not less than the predetermined value f(v), the braking force exerted on the rear wheels is less than the braking force exerted on the front wheels, and when the deceleration d is less than said predetermined value f(v), the braking force exerted on the rear wheel is increased. - View Dependent Claims (8, 9, 10, 11)

12. A braking control method for vehicles, which controls braking forces exerted on front and rear wheels of a vehicle respectively, the method comprising steps of:
-
determining a speed v and a deceleration d of the vehicle;
determining a predetermined value f(v) that is a function value determined according to said speed v of the vehicle and said predetermined value f(v) becomes smaller with increase in said speed v;
determining if the deceleration d determined satisfies such a control condition that the deceleration d is not less than the predetermined value f(v); and
performing such control that when said control condition is satisfied, the braking force exerted on the rear wheels is less than the braking force exerted on the front wheels, and when the deceleration d is less than said predetermined value f(v), the braking force exerted on the rear wheel is increased. - View Dependent Claims (13, 14, 15, 16)
