Abstract

Honda has developed a variety of innovative motorcycle brake technologies. Super sport motorcycles, CBR600/1000RR, have a unique combination of short wheel bases and center of gravity locations as vehicle characteristics, and the possibility towards pitching under hard braking has prevented conventional ABS from being used in these motorcycles. In addition, the characteristics of mechanical combined brake systems (CBS) make it challenging to adapt them for sport riding. Therefore, a new brake-by-wire system has been developed in which brake input is detected by a hydraulic sensor and the brake hydraulic pressure is varied by a power unit. A newly developed stroke simulator has enabled the achievement of an operation feeling similar to that of a conventional brake. In addition, the precise control of hydraulic pressure achieved by this system has enabled pitching to be controlled and made ABS/CBS compatible with sport riding. The new system represents a first for super sport motorcycles, and has been employed in the 2009 model year CBR600/1000RR.
