Haptic feedback system for motor car, has electric motor, worm gear, and threaded spindle producing oscillations in steering wheel by repeated exchanging of rotational direction of motor, and introducing oscillations into steering column

摘要

The system has a steering train including an electric motor (8), a flanged worm gear (9), and a threaded spindle (10) for a steering function of the steering train or for a displacing function of a steering column (1). The motor, the worm gear, and the spindle produce oscillations in a steering wheel by repeated exchanging of a rotational direction of the electric motor, and introduce the oscillations into the steering column. The electric motor, the worm gear, and the threaded spindle actuatingly influence a transmission ratio between a steering wheel weft and a wheel steering angle.
