PEDAL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240319758 titled 'PEDAL DEVICE

The abstract of the patent application describes a pedal device that includes a pedal lever, an actuator, and a control unit. The pedal lever responds to pedal operation, the actuator applies a reaction force to return the pedal lever, and the control unit calculates and controls the motor drive based on the reaction force.

• The pedal device includes a pedal lever, actuator, and control unit.
• The actuator can apply a reaction force to return the pedal lever by driving a motor.
• The control unit calculates a current command value and duty command value based on the reaction force target value.
• The control unit corrects the duty command value based on motor current and rotation speed.
