Abstract: A gearbox shifting point for producing a rotationally fixed connection between at least one gearwheel and one shaft. The gearbox shifting point comprises a shaft, a shifting sleeve and two gearwheels. The two gearwheels are each rotatably mounted in relation to the shaft. The shifting sleeve is mounted in a rotationally secured fashion on the shaft. The shifting sleeve and the gearwheels are embodied in such a way that a positively locking, rotationally fixed connection can be produced between the shifting sleeve and in each case one gearwheel. In order to improve problems with respect to a gearshifting hole or blockage of the gearbox, the shifting sleeve interacts with the two gearwheels in such a way that at least one positively locking, rotationally fixed connection is always produced between the shifting sleeve and one of the gearwheels.

Abstract: A vehicle control system includes a pedal, such as an accelerator pedal, an adjusting device, a sensor and a control unit. The pedal may be actuated by the hand of an operator to set a state variable of the vehicle. The adjusting device applies a force to the pedal. A sensor senses a variable representing a state variable of the vehicle and transmits a sensor signal to the control unit. The control unit determines a state variable of the current operating state of the vehicle. The control unit, depending on the current operating state of the vehicle, controls the adjusting device so that a predetermined force is applied to the pedal, in order to make the operator aware of an unsafe operating condition.
