A method for operating a braking system for a motor vehicle, including a service brake unit and the service brake unit is activated to generate a brake force on a wheel axle of the motor vehicle at least temporarily as a function of a setting of an operating element. The generation of the brake force is performed using a calibration data set stored in a control unit of the braking system. An identifier stored in the operating element is transmitted to the control unit and used for a compatibility check. If the compatibility check is successful, a configuration of the operating element takes place and a generic data set stored in the control unit is used as the calibration data set and an operating element-specific data set stored in the operating element is transmitted to the control unit and used as a calibration data set after the transmission.

The invention relates to a transmission structure for a hybrid vehicle with an internal combustion engine, a first electric machine, and a second electric machine. In this case, a first electric machine shaft which is assigned to the first electric machine can be driven by a drive shaft which can be driven by the internal combustion engine via a first gear set. In this case, a travel drive gear of a differential gearing of the vehicle can be driven by a second electric machine shaft assigned to the second electric machine via a second gear set. The transmission structure can thereby be compactly designed and in particular, the use of the installation space and/or the efficiency of the electric machines can be improved in that the first gear set has a ring gear with inner teeth and a spur gear which engages with the inner teeth of the ring gear.

Transmission structure for a serial/parallel hybrid vehicle

A drive train for a hybrid motor vehicle having a gearbox input shaft operatively connected to a first electric machine and an internal combustion engine via a first partial drive train to transmit torque and which is operatively connected to a second electric machine via a second partial drive train to transmit torque. The second electric machine is permanently connected to the gearbox input shaft for torque transmission and the first electric machine and the internal combustion engine can be connected to the gearbox input shaft in a coupleable manner to transmit torque. The first electric machine and the second electric machine are arranged coaxially to one another, and driven shaft of the first electric machine is arranged radially inside a driven shaft of the second electric machine. The driven shaft of the first electric machine is mounted on the driven shaft of the second electric machine via a bearing.

Methods for recognizing an input of a person with a sensor, wherein the input is recognized by the sensor by at least one gesture of the person assigned to the input, wherein a first gesture for sensing the input is applied, said gesture being sensed by the sensor, wherein a functionality of the sensor for sensing the first gesture is checked, wherein, in the event that the functionality for recognizing the first gesture is not given, alternatively a second gesture is selected and assigned to the input, wherein a switch is made from the first gesture to the second gesture for recognizing the input by the sensor.

An oil pump configuration for a motor vehicle includes an oil pump having a pump part and an electric pump motor, wherein the pump part is operatively connected to the electric pump motor. The pump part and/or the electric pump motor can be mounted to a housing which at least partially delimits an oil chamber. Sealing problems at the pump part are prevented and the required installation space is low because the pump part can be mounted inside the housing and the electric pump motor can be mounted from the outside to the housing.

Oil pump configuration for a motor vehicle

A method for operating an anti-theft device for a motor vehicle which is unlocked when a radio signal is received from a radio-based remote control device of the motor vehicle and, after unlocking, is started by actuating a start/stop operating element. Here, an interior of the motor vehicle is monitored by a detection device of the anti-theft device after the motor vehicle has been started. For the monitoring of the interior of the motor vehicle, a search signal restricted to the interior is output by the detection device in the interior of the motor vehicle. The radio-based remote control device is configured to output a detection signal when the search signal is received. If the detection signal is not received by the detection device before a predetermined search time, a warning message is output to a unit outside the vehicle.

A locking device for a motor vehicle. A transmitting device, which is designed to send out a request signal into a surroundings of the motor vehicle in dependence on a predetermined triggering event, as well as a receiving device, which is designed to receive, within a predetermined time interval from the sending of the request signal in a predetermined frequency region, a response signal of a radio key from the surroundings, and a control device, which is designed, in event of a response signal received within the time interval, to unlock at least one lock of the locking device. An evaluation module is designed so that the transmitting device sends out an interference radio signal after the sending of the request signal within the time interval at least at one radio frequency lying outside the frequency region.
