Abstract: 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.

Abstract: 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.

Abstract: A turn signal canceling device for a motorcycle includes a straight-ahead travel or turn determining unit for determining whether the motorcycle is travelling straight ahead or is turning and a turn signal cancellation controller which automatically cancels turn signal operation. When a vehicle speed is not greater than a predetermined speed and a driving force is at least a predetermined driving force at a time the straight-ahead travel or turn determining unit determines that the motorcycle is turning, the turn signal cancellation controller enters a standby state. When the straight-ahead travel or turn determining unit determines that the motorcycle is travelling straight ahead during the standby state, the turn signal cancellation controller automatically deactivates a turn signal. When the driving force becomes smaller than the predetermined driving force or turn signal becomes manually deactivated during the standby state, the turn signal cancellation controller returns to the normal operating state.

Abstract: A turn signal cancelling device for a motorcycle includes turn signal cancellation control unit configured to automatically deactivate a second turn signal after a second predetermined time has passed or after the motorcycle has travelled a second predetermined distance since an activation the second turn signal. The turn signal cancellation control unit is configured to automatically deactivate the second turn signal in a case where the activation of the second turn signal is performed before a first predetermined time has passed or before the motorcycle has travelled a first predetermined distance since an activation of a first turn signal is performed when a vehicle speed is equal to or higher than a predetermined speed.

Abstract: A straight-traveling/turning determination device includes a straight-traveling/turning determiner that determines whether a motorcycle is traveling straight or turning by comparison between a threshold and a rotary speed comparison value that is a value resulting from comparison between the rotary speed of a front wheel and the rotary speed of a rear wheel. The straight-traveling/turning determiner uses the rotary speed comparison value in the state in which the vehicle speed is equal to or lower than first predetermined speed and an absolute value of the vehicle acceleration is equal to or lower than predetermined acceleration and a turn signal is not being actuated as a straight-traveling rotary speed comparison value, and determines that the motorcycle is turning if a ratio or difference between the rotary speed comparison value and the straight-traveling rotary speed comparison value becomes larger than a threshold.

Abstract: A lighting control system is provided with a blinker switch, a hazard switch, and a control circuit which controls the flashing of blinker lamps. The CPU of the control circuit, after detecting an input signal from one switch input port among a left side and a right side switch input port, determines that the hazard switch is switched on when an input signal from the other of the switch input ports is detected within a predetermined time, and determines that the blinker switch is switched on when no input signal from the other of the switch input ports is detected.

Abstract: An operation amount detecting unit 17 detects an operation amount of a throttle grip from a zero position. A basic throttle opening degree computing unit 18 computes a basic throttle opening degree corresponding to the operation amount. A throttle opening degree additional value computing unit 20 outputs as a target throttle opening degree a value obtained by adding the basic throttle opening degree with a throttle opening degree additional value corresponding to the operation amount when the operation of the throttle grip is performed within a small operation region corresponding to an idle operation. The throttle opening degree additional value computing unit 20 outputs as the target throttle opening degree the basic throttle opening degree when the operation of the throttle grip is performed without the small operation region.

Abstract: To provide a vehicle speed limiting system that is capable of executing a maximum speed limiting control without influencing a driving feeling of a vehicle. A vehicle speed limiting system includes: a three-dimensional map 46a and a throttle valve driving unit 47. A first maximum speed limiter opening degree is calculated by adding a first predetermined opening degree, a second predetermined opening degree, and a current throttle valve opening degree, the first predetermined opening degree being calculated by multiplying a speed difference of the vehicle by a preset P-term coefficient, the second predetermined opening degree being calculated by multiplying an acceleration of the vehicle by a preset D-term coefficient. Once the calculated first maximum speed limiter opening degree falls below the target throttle valve opening degree ?B, the throttle valve motor 30 is driven on a basis of the first maximum speed limiter opening degree.

Abstract: The cleaning treatment apparatus of the present invention is constituted so that a cleaning liquid is continuously supplied by a liquid film forming means in a gap formed between a surface of a processed member held horizontally and rotationally driven by a holding and rotating means and a ultrasonically oscillating lower face of a ultrasonic oscillating means, to thereby form a liquid film in the gap. Hereby, the surface of the processed member is subjected to a cleaning treatment by the liquid film, which is ultrasonically oscillated by the ultrasonic oscillating means. At this stage, as the processed member is rotated by the holding and rotating means, the surface of the processed member is properly cleaned by the ultrasonically oscillating cleaning liquid not only in a region thereof opposed to the ultrasonic oscillating means during the standstill of the member but also in a region thereof opposed to the ultrasonic oscillating means during the rotation of the member.
