Abstract
A pedal emulator for a vehicle, having a rotational axis, a pedal lever that can be rotated about the rotational axis, and a force generation unit for exerting a counterforce on the pedal lever via at least one coupling element of the force generation unit that is mechanically coupled to the pedal lever. The counterforce acting in the opposite direction to an actuation force exerted on the pedal lever. The force generation unit can be designed such that a curve of the counterforce along a pedal path of the pedal lever is in the form of a non-linear curve in a pedal path-counterforce diagram.
Claims16
A pedal emulator for a vehicle, the pedal emulator comprising:
- a rotational axis;
- a pedal lever that is rotatable about the rotational axis;
- and
- a force generator to exert a counterforce on the pedal lever by at least one coupling element of the force generator that is mechanically coupled to the pedal lever, the counterforce acting oppositely with respect to an actuating force exerted on the pedal lever, and the force generator being designed such that a profile of the counterforce along a pedal travel of the pedal lever in a pedal travel-counterforce diagram is a nonlinear profile,
- wherein the force generator has a restoring element, a first end of the restoring element being mechanically coupled to the rotational axis and a second end of the restoring element being mechanically coupled to the coupling element via a reset carrier,
- wherein the first end of the restoring element is mechanically coupled to the rotational axis by being directly supported on the pedal lever or by being directly supported on an intermediate lever, the intermediate lever having a first end that is mounted directly at the rotational axis so that the intermediate lever rotates about the rotational axis, and
- wherein the second end of the restoring element is directly supported on a spring seat of the reset carrier, and the reset carrier is directly coupled to a first end of the coupling element so that the reset carrier directly contacts the first end of the coupling element.
