ACTIVE ACCELERATOR PEDAL FOR A VEHICLE
First Claim
1. A vehicle, comprising:
- a drive unit configured to generate a drive torque in driving relationship to wheels of the vehicle;
a gas pedal constructed in the form of an active accelerator pedal which is adjustable over a pedal travel;
a control device configured to activate the drive unit in response to a desired torque given by a driver through actuation of the accelerator pedal, said control device including an evaluation unit; and
an actuator operatively connected to the control unit and configured to apply a resistance force upon the accelerator pedal, thereby generating a pressure point for the accelerator pedal, with the resistance force increasing in a locally limited pedal travel interval up to a maximum force which can be overridden by the driver,said evaluation unit being configured to generate a deactivation signal within the pedal travel interval, when the accelerator pedal reaches a predefined limit hold time to thereby enable a decrease of the resistance force.

Abstract
A vehicle includes a drive unit configured to generate a drive torque in driving relationship to wheels of the vehicle, and a gas pedal constructed in the form of an active accelerator pedal which is adjustable over a pedal travel. A control device activates the drive unit in response to a desired torque given by a driver through actuation of the accelerator pedal. Operatively connected to the control device is an actuator which applies a resistance force upon the accelerator pedal, thereby generating a pressure point for the accelerator pedal, with the resistance force increasing in a locally limited pedal travel interval up to a maximum force which can be overridden by the driver. An evaluation unit of the control unit generates a deactivation signal within the pedal travel interval, when the accelerator pedal reaches a predefined limit hold time.

9. An active accelerator pedal for a vehicle, said active accelerator pedal being adjustable over a pedal travel and constructed for actuation by a driver to generate a predefined desired torque transmitted to a control unit which actuates a drive unit in response to the defined desired torque, with a resistance force being imposed on the active accelerator pedal from an actuator operatively connected to the control unit to thereby generate a pressure point for the accelerator pedal, with the resistance force increasing in a locally limited pedal travel interval up to a maximum force which can be overridden by the driver, wherein a deactivation signal within the pedal travel interval is generated by an evaluation unit of the control unit, when the accelerator pedal reaches a predefined limit hold time to thereby enable a decrease of the resistance force.

10. A method, comprising:
-
depressing by a driver an active accelerator pedal to generate a desired torque; transmitting the desired torque to a control unit for operating a drive unit in response to the desired torque; imposing a resistance force on the active accelerator pedal from an actuator operatively connected to the control unit, thereby generating a pressure point for the accelerator pedal, with the resistance force increasing in a locally limited pedal travel interval up to a maximum force which can be overridden by the driver; and generating a deactivation signal within the pedal travel interval, when the accelerator pedal reaches a predefined limit hold time to thereby enable a decrease of the resistance force.
