Abstract: The disclosure relates to a method for operating a steering system of a vehicle having a front-axle steering assembly, a rear-axle steering assembly and a steering wheel. The method involves detecting a failure of the front-axle steering assembly, steering the vehicle exclusively via the rear-axle steering assembly based on a steering command issued by a driver via the steering wheel, comparing at least one detected physical value of the steering command with a limit value associated with the rear-axle steering assembly and, provided the at least one associated limit value is reached or exceeded by the at least one detected physical value of the steering command, applying a torque acting on the steering wheel via the electric motor coupled to the steering wheel, which torque counteracts the steering command.

Abstract: A protection system for a motor vehicle having a sensor for determining an angle of inclination of the motor vehicle about its longitudinal axis. An airbag attached on an outside of the motor vehicle. A processing device designed to detect a risk that the motor vehicle may tip over, on the basis of the inclination angle determined, and in that case activates the airbag. The airbag can be pivoted in the vertical direction from an area close to the ground.

Abstract: An oil supply arrangement of a vehicle with an electric machine in a housing with at least one oil volume connected to an oil volume of a transmission housing of the vehicle for oil supply. The oil volume of the electric machine is divided into at least two oil supply spaces to compensate an oil level in the housing. A first oil supply space is arranged at a side of the housing facing the driving direction of the vehicle and a second oil supply space is arranged at a side of the housing opposite the driving direction of the vehicle.

Abstract: A gearwheel for a gear system for a planetary gear system of a chassis assistance system. The gearwheel is divided into at least a first spur gear and a second spur gear which are spaced apart from one another along a common rotational axis. The gearwheel has, in addition, an open spring ring with a first end, which is supported in a circumferential direction against the first spur gear, and a second end, which is supported in the direction opposite to the circumferential direction against the second spur gear in such manner that by rotating the spur gears, relative to one another about the common rotational axis, the spring ring can be stressed in order to exert a restoring torque on the spur gears. A recess is formed on at least one of the spur gears for holding part of the spring ring.

Abstract: A charging vehicle (1) for charging an electric vehicle (2) has a charging system (3), a charging regulator (4), a control device (5) and a contact system (6). The charging system (3) is connected to the charging regulator (4) and the contact system (6). The contact system (6) serves to supply the charging vehicle (1) with electric energy. The charging system (3) is a contactless charging system (3). The charging vehicle (1) can be controlled by the control device (5) in a longitudinal direction and a transverse direction and can be positioned, by the control device (5), into a charging position (7).

Abstract: A parking vehicle for the transport and parking of an electric vehicle. The parking vehicle has a platform on which the electric vehicle can be parked and has a charging system to charge the electric vehicle. The charging system has an electric energy storage which is connected to a contact system. The charging system is connected to the platform. The parking vehicle is connected to an electric energy supply which is connected to the charging system. The parking vehicle has a charging regulator connected to the charging system. The parking vehicle has a communications device which transmits and receives the data of an external system. The parking vehicle has a control device connected with the communications device. Movement of the parking vehicle is controlled in longitudinal and transverse directions by the control device.
