Method for operating an accelerator pedal unit for motor vehicles

摘要

A method for operating an accelerator pedal unit for motor vehicles, wherein a change in position of the pedal plate, which is brought about by a corresponding activation force, with respect to the starting position of said pedal plate counter to a restoring force of a pedal restoring spring brings about an increase in the driving force of the drive motor of the motor vehicle, and when the activation force diminishes the restoring force of the pedal restoring spring moves the pedal plate back in the direction of its starting position, wherein an electromechanical actuator which can be actuated externally is arranged in such a way that an additional restoring force acting on the pedal plate can be set.

1. A method for operating an accelerator pedal unit for motor vehicles, wherein a change in position of a pedal plate, which is brought about by a corresponding activation force, with respect to the starting position of said pedal plate counter to a restoring force (Fres) of a pedal restoring spring brings about an increase in the driving force of the drive motor of the motor vehicle, and when the activation force diminishes the restoring force of the pedal restoring spring moves the pedal plate back in the direction of its starting position, wherein an electromechanical actuator which can be actuated externally is arranged in such a way that an additional restoring force (Fadd) acting on the pedal plate can be set, wherein a calibration process is carried out, with the result that a linear relationship is implemented between the setpoint current request (Isetp) to the electromechanical actuator and the additional restoring force (Fadd) over the entire pedal stroke (S).
