20150127234 | METHOD AND CONTROL DEVICE FOR CONTROLLING A HAPTIC ACCELERATOR PEDAL OF A MOTOR VEHICLE BY MEANS OF A POSITION CONTROL - A method and to a control device for controlling a haptic accelerator pedal in a motor vehicle includes displacing a pedal lever in an actuation direction between a rest position and a maximally actuated position. The pedal lever is configured to be excited by an actuator by exerting a counter force against the actuation direction to generate a haptically perceivable signal. A current position of the pedal lever relative to a current position of the actuator is determined outside the phases for generating the haptically perceivable signal, and the actuator is subsequently controlled in such a manner that the actuator actively follows a change in the determined position of the pedal lever. The positional control is configured to prevent interfering influences on the pedal lever by the actuator. | 05-07-2015 |
