Abstract: A sensor device for detecting a motion state of a motor vehicle. The sensor device includes at least one laser unit having a light source for emitting coherent light which is transmitted in the direction of a roadway surface, and an interference detector which is designed to detect at least one measurement variable which characterizes interference between the light scattered at the surface and the light of the light source. The measurement variable represents a speed component of the sensor device and/or a distance between the sensor device and the roadway surface. The laser unit is coupled to an evaluation device which is designed to determine, from the measurement variable, at least one variable which characterizes the motion state of the vehicle, in particular a speed component of the center of gravity of the vehicle, a rotational angle or a rotation rate of the vehicle.

Abstract: Disclosed is a tire pressure-monitoring device for a motor vehicle, having at least one control unit (6) and/or at least one central box (10) being connected to the wheel house transceivers (4) arranged in the area of the wheel houses by way of wheel speed sensor and control conduits (5) or by way of wheel speed sensor conduits (11) and actuating conduits (13), which transceivers are appropriate for the wireless unidirectional or bidirectional transmission of information and energy to a transponder (1) arranged in the wheel or tire proximate the wheel house.

Abstract: A vehicle with a working device, especially a chopping device, with a drive element, which is connected to an output shaft of the vehicle, whereby the transmission element can be moved on bearings and the working device can change position with respect to the vehicle.
