Title:
ACCELERATOR PEDAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/157949
Kind Code:
A1
Abstract:
This accelerator pedal device includes: an accelerator pedal (20); a hysteresis generation mechanism (40) that generates a hysteresis in pedal effort when depressing and returning the accelerator pedal; a reaction force addition mechanism (60) that adds reaction force in a direction to push back the accelerator pedal; and a control unit (70) that controls the drive of the reaction force addition mechanism (60) so that, with a predetermined target opening degree (θt) at which the accelerator pedal is depressed as a boundary, the ratio (ΔN/Δθ) of change in pedal effort (N) in an opening degree range larger than a target opening degree (θt) becomes relatively larger than the ratio (ΔN/Δθ) of change in the pedal effort (N) in an opening degree range smaller than the target opening degree (θt). Thus, a driver can easily maintain the accelerator pedal at an accelerator position according to various driving modes without feeling uncomfortable or tired.
