METHOD AND CONTROL DEVICE FOR CONTROLLING A HAPTIC ACCELERATION PEDAL THAT IS TO BE SET IN OSCILLATION IN A MOTOR VEHICLE

摘要

The invention relates to a method and to a control device (3) for controlling a haptic acceleration pedal (11) in a motor vehicle (1). According to the invention, a temporally varying actuation force (F) is generated by means of an actuator (13) in the acceleration pedal (11) during a signal phase (ts) in order to set the acceleration pedal (11) in oscillation. The actuator (13) is controlled in such a manner that at least a minimum force (Fmin) is applied to the acceleration pedal (11) during the entire signal phase (ts). In particular when the actuator (13) is formed using a simple, cost effective direct current motor (23) and a drive unit (25) coupled thereto, it is possible in said manner to prevent operational interruptions in the drive unit (25) during the signal phase (ts) and thus an imprecise generation of the haptically perceivable signal in the acceleration pedal (11) and the generation of noise.
