<p><P>PROBLEM TO BE SOLVED: To easily process an output for determining a shift position of a transmission with a CPU. <P>SOLUTION: A resistance circuit is formed of a plurality of resistances 41-48, and 51 connected in series. A plurality of shift position contact points 34-40 are connected to each contact point of the resistances 41-48, and 51. A movable terminal 33 supported on a common rotary shaft with a shift drum 7 is disposed slidingly movably on the shift position contact points 34-40. The movable terminal is grounded. Voltage is supplied to both ends of the resistance circuit from a DC power source 52. Partial pressure of the power source voltage detected in the middle of the resistance circuit changes by the grounding position of the movable terminal 33. The partial pressure of the power source voltage is A/D converted and connected to a port of the CPU 54. The CPU 54 detects the shift position by comparing a theoretical value of a resistance partial pressure corresponding to the shift position and the input voltage of the port, and outputs a detection signal for displaying the detected result. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
