Abstract
A device for varying a pedal resistance of a hydraulic brake system includes at least one electroactive polymer actuator. The device further includes a reaction disc. The reaction disc has at least two polymer actuators. The at least two polymer actuators are independently controllable. Additionally, the at least two polymer actuators are arranged coaxially relative to one another.
Claims13
A device for varying a pedal resistance of a hydraulic brake system, comprising:
- at least one electroactive polymer actuator;
- and
- a reaction disk, the reaction disk including at least two polymer actuators
- wherein the at least two polymer actuators are configured to be actuated independently of one another and are arranged coaxially to one another.
A brake system for a vehicle, comprising:
- a main brake cylinder;
- a brake pedal configured to displace a piston in the main brake cylinder;
- a brake booster;
- and
- a device configured to vary a pedal resistance of the brake pedal, the device including:
- at least one electroactive polymer actuator;
- and
- a reaction disk, the reaction disk including at least two polymer actuators,
- wherein the at least two polymer actuators are configured to be actuated independently of one another and are arranged coaxially to one another.
A method for operating a device including at least one electroactive polymer actuator and a reaction disk, the reaction disk including at least two polymer actuators which are configured to be actuated independently of one another and are arranged coaxially to one another, the method comprising:
- actuating the at least two polymer actuators independently of one another as a function of a desired pedal resistance.
