Publication number: 20150006042Abstract: A shift position detecting device where a shift position determining member is provided for determining a shift position based on a combination of switching modes of three switches corresponding to at least one of a plurality of projection rows each having a plurality of projection portions in a one-by-one basis, and “1, 1, 1” indicative of an ON state of each switch is allocated as a detection logic at a neutral position arranged between a first speed position and a second speed position, wherein a change in friction at the time of a shift operational to the neutral position is alleviated thus giving an operational feeling with no discomfort to a rider. Two projection rows that are objects to be detected by two specified switches among the three switches are formed so as to change switching modes of the specified switches from an OFF state to an ON state.Type: ApplicationFiled: June 25, 2014Publication date: January 1, 2015Inventors: Takashi HOTEI, Takashi TETSUKA, Dai ARAI, Atsushi CHIBA

Publication number: 20150000448Abstract: A shift position detecting device that determines a shift position based on a detection logic formed of a combination of turning on or off of a plurality of switches that are fixedly arranged at least one by one at positions corresponding to a plurality of detecting object portion rows mounted on a shift drum. An accurate shift position can be detected even if there is an irregularity in switching timings of switching modes of the plurality of switches. A shift position detecting member establishes the shift position as a new shift position and outputs shift position information, while when the detection logic after the transition is a detection logic other than the detection logic corresponding to the changeable shift position, sets the new shift position not yet established and outputs information corresponding to non-establishment of the shift position.Type: ApplicationFiled: June 3, 2014Publication date: January 1, 2015Inventors: Takashi TETSUKA, Takashi HOTEI, Dai ARAI, Atsushi CHIBA, Kenichi TAMURA
