ACCELERATOR PLAY MEASUREMENT DEVICE, ACCELERATOR PLAY MEASUREMENT METHOD, PROGRAM, AND MEDIUM

摘要

This accelerator play measurement device measures the play opening of an accelerator pedal of a vehicle, and includes: an accelerator actuator for operating the accelerator pedal; a vehicle speed sensor for detecting the vehicle speed of the vehicle; a first measurement unit for calculating a provisional play opening on the basis of a change in vehicle speed detection value from the vehicle speed sensor when the accelerator actuator has been driven and the accelerator pedal opening degree has been increased at a first speed from a fully-closed opening degree; and a second measurement unit for detecting the play opening on the basis of a change in vehicle speed detection value when the accelerator actuator has been driven and the accelerator pedal opening degree has been increased at a second speed higher than the first speed from the fully-closed opening degree to close to the provisional play opening.
