Automobile haptic accelerator pedal with elastically coupled actuator, method for closed-loop control of the haptic accelerator pedal, and closed-loop control unit

摘要

A pedal system for a motor vehicle, such as an accelerator pedal system, includes an elastic coupling element, a control unit, a pedal lever, and an actuator. The elastic coupling element is operatively positioned between the pedal lever and the actuator, and has a relatively low stiffness. The control unit is configured to control the actuator. The elastic coupling element is configured to damp brief force and/or torque fluctuations occurring in, for example, the actuator, such that said force and/or torque fluctuations are not transmitted to the pedal lever. A spring deflection of the elastic coupling element, in a direction of force applied to the pedal lever, operates as a control variable for controlling the actuator. A method relates to controlling such a haptic accelerator pedal and a correspondingly configured control unit.
