Abstract
A control pedal device includes: a pedal configured to receive an operation; a pedal arm attached to the pedal to be movable with the pedal; a rotating shaft fixed to the pedal arm; a reaction force generating mechanism exerting a reaction force against the operation of the pedal; multiple targets attached to the rotating shaft and rotating together with the rotating shaft; and multiple sensor elements configured to detect a rotation of the multiple targets.
Claims19
A control pedal device for a vehicle, comprising:
- a pedal configured to receive an operation;
- a pedal arm attached to the pedal to be movable with the pedal;
- a rotating shaft fixed to the pedal arm;
- a reaction force generating mechanism configured to exert a reaction force against the operation of the pedal;
- multiple targets attached to the rotating shaft and rotating together with the rotating shaft;
- and
- multiple sensor elements configured to detect a rotation of the targets;
- wherein at least two of the multiple sensor elements are configured to detect a rotation of the multiple targets using respective detection principles different from each other.
