Accelerator position detection device with improved abnormal detection

Abstract:

An accelerator position detection device includes a handlebar grip that is turnable in a normal rotation direction and in a reverse rotation direction from a neutral position and is energized to the neutral position when no operation is applied; accelerator position sensors that output voltage according to an angle of the handlebar grip and that include a first sensor and a second sensor; and a detector that detects an angle for control for controlling a vehicle on the basis of the angle of the handlebar grip according to output from the accelerator position sensors. The detector detects an angle as a positive value on the basis of a first voltage when the first voltage in a rising range is output, and the detector detects an angle as a negative value on the basis of a second voltage when a first initial value not located in the rising range is output.
