Patent 9187069 was granted and assigned to Honda on November, 2015 by the United States Patent and Trademark Office.
To prevent deterioration of sports driving performance due to the actuation of an ABS in a front-wheel and rear-wheel interlocking brake system of a brake-by-wire system. A brake interlock determining portion starts a front-wheel brake when input hydraulic pressure by a brake operation (pedal operation) on a rear-wheel becomes equal to or greater than an interlocking brake starting pressure value. A threshold selecting switch allows switching of the interlocking brake starting pressure value between when the ABS is active and when the ABS is inactive. When the ABS is active, a lower pressure value is selected as the interlocking brake starting pressure value. When the ABS is inactive, an upper pressure value is selected as the interlocking brake starting pressure value.
