Abstract:
An accelerator opening degree sensor for detecting a pedaling amount of an accelerator pedal as an output voltage, comprising:an accelerator pedal; a pedaling amount/voltage conversion means for changing a ratio of change of said output voltage with respect to said pedaling amount, wherein said pedaling amount/voltage conversion means includes: a variable region comprising said resistive layer and constructed to increase said output voltage in accordance with increase in said pedaling amount; an invariable region comprising said resistive layer and a conductive layer embedded in said resistive layer and constructed to give a substantially constant value of said output voltage with respect to change of said pedaling amount; and a sliding element connected to said accelerator pedal and making sliding contact, corresponding to said pedaling amount, on a resistor material layer spanning said variable region and said invariable region; wherein said variable region includes a region from a position in a vicinity of start of pedaling of an accelerator pedal to a pedaling end position; wherein said invariable region includes a region from a pedaling start position of an accelerator pedal to a position in the vicinity of said start of pedaling, and further comprises a stepped region constructed such that the output voltage with respect to a change in pedaling amount is a predetermined value larger than a zero value.
