Abstract: A brake device 10 for a motorcycle is capable of electrically performing driving so as to control a front wheel brake caliper 16 and a rear wheel brake caliper 18 in response to each operation of a brake lever 12 and a brake pedal 14 and is configured so that the rear wheel brake caliper 18 and the front wheel brake caliper 16 can be combined based on the operation of the brake pedal 14. The brake device 10 performs correction of a target hydraulic pressure acting on the front wheel brake caliper 16 using a prescribed preset function in such a manner as to give a braking force smaller than a braking force corresponding to an additional operation of the brake lever 12 when the brake lever 12 is additionally operated in the state where the brake pedal 14 is operated and the front wheel brake caliper 16 is generating braking force in combination with the rear wheel brake caliper 18.

Abstract: A vehicle braking apparatus is capable of suppressing time lag at the time of activating an ABS, reliably detecting wheel slippage at a wheel even on a low ? road surface, and performing a brake operation to stop the vehicle without causing stroke variations in a brake actuating unit. A vehicle braking apparatus includes a hydraulic modulator for generating hydraulic pressure applied to a brake caliper which is connected to a master cylinder via a main brake path, and a pressure sensor for detecting hydraulic pressure applied to the brake caliper. When the ABS is activated, the hydraulic pressure applied to the brake caliper is reduced to a pressure reduction target value based on the detected pressure. A normally-open electromagnetic valve lies in the main brake path. The brake path pressure on each side of the valve is equalized by means of the hydraulic modulator before opening the electromagnetic valve.
