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

摘要

The purpose of the present invention is to provide an accelerator play measurement device that makes it possible to measure the play opening of an accelerator pedal of a vehicle without using the engine rotational speed. This accelerator play measurement device measures the play opening of an accelerator pedal of a vehicle, and comprises: 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.
