Abstract: Motor vehicle configuration system, including a motor vehicle, in the interior of which at least one transponder that is capable of wireless near field communication is attached and which has a receiving unit for wireless reception of vehicle configuration data over a wireless communication link independent of the wireless near field communication. A portable device has at least one data memory for storing the memory data and has a transmitting unit for a wireless transmission of data on the basis of the memory data. The portable device is programmed such that, when an approach of the portable device to a transponder is detected on the basis of wireless near field communication, the data are transferred from the portable device to the motor vehicle a wireless communication link between the transmitting unit and the receiving unit for the purpose of providing the motor vehicle with configuration data. The communication link is independent of the wireless near field communication.

Abstract: A system and method for supplying voltage to electrical loads in the onboard electrical system of a motor vehicle are provided. The onboard electrical system consists of at least two onboard electrical system regions. The first onboard electrical system region has an electric generator, a vehicle battery, as well as one or more first electrical loads. The second onboard electrical system region has a double-layer capacitor or a so-called supercap and one or more second electrical loads. Between the two onboard electrical system regions, a blocking device is provided, in particular, a semiconductor diode or a power switch, which permits a current flow from the first onboard electrical system region into the second electrical system region and largely prevents a reverse current flow from the second onboard electrical system region into the first onboard electrical system region.

Abstract: A method ensures the standstill of a motor vehicle. Before reaching the standstill, an electronic control unit checks whether a predefined inclination threshold is exceeded, whether the velocity has fallen below a predefined travel velocity threshold, and whether there is a negative vehicle acceleration. If all three conditions exist simultaneously, an increased setpoint braking torque is predefined until the motor vehicle reaches the standstill.

Abstract: A method is provided for automatic shutdown of an internal combustion engine in a motor vehicle, in particular in a vehicle having an automatic transmission, by way of a stop-start unit which automatically shuts down the internal combustion engine when the vehicle is decelerated to a standstill and kept at a standstill by operation of the brake pedal for a predetermined interval of time. Within the predetermined interval of time, the driver is given an opportunity to prevent the automatic shutdown. According to the invention, an automatic shutdown is prevented when the driver of the vehicle depresses the brake pedal fully within the predetermined interval of time and then releases the brake pedal again.

Abstract: For the automatic longitudinal guidance of a motor vehicle having a longitudinally guiding driver assistance system with a stop-and-go function, at least starting from a point-in-time wherein the motor vehicle is stopped, the vehicle apron is continuously monitored for possible obstacles by a monitoring device having a camera which supplies a sequence of individual images of the vehicle apron. For the detection of obstacles in the vehicle apron, characteristic image features are extracted from the individual images and are tracked with respect to time within the sequence of individual images, and an appearance and/or disappearance of one or more characteristic image features taking place in the course of the sequence is determined and evaluated. Additionally or alternatively, a change of a spatial distribution of one or more characteristic image features taking place in the course of the sequence in the respective individual image or in a cutout of the latter is determined and evaluated.

Abstract: An information system includes a central computer system and at least one user device. The central computer system has a database and an interface for communicating with a user device. The database is designed for storing personalized information with reference to a location and program functions with reference to a location. The database is also designed for synchronizing the personalized information and/or program functions with the respective user device. For this purpose, the user device is configured so as to determine a position of a moveable object as a function of at least one position-measuring signal and to provide, as a function of the determined position, personalized information with reference to a location and/or a program function with reference to a location.

Abstract: A method is provided for operating a hold function for temporarily holding an operationally ready motor vehicle in a stationary state by use of a service brake. The service brake is actuated by electrohydraulic, electropneumatic or electromechanical mechanisms. The service brake can be activated within the framework of the hold function, when the speed of the vehicle is less than a preset first speed threshold, and the presence of the driver in the driver's seat is detected. The presence of the driver in the driver's seat is detected as a function of the signal of a flap sensor for detecting an opened or closed position of the flap, assigned to this flap sensor.

Abstract: An operator control device for operating a plurality of functions, in particular, in a vehicle, has at least a first rotary actuator and a second rotary actuator. A respective rotary actuator is assigned a function of the vehicle. The first rotary actuator has a first rotary body and a first operator control body, where the first operator control body is mechanically coupled with the first rotary body. The second rotary actuator has a second rotary body and a second operator control body, where the second operator control body is mechanically coupled with the second rotary body. The first rotary body and the second rotary body are arranged coaxially in each other such that they can be rotated about a common axis of rotation. At least one operator control body has a grip area that is designed in a lever-like manner.

Abstract: A method is provided for the selective catalytic reduction of nitrogen oxides in the exhaust gas of internal-combustion engines in motor vehicles, reducing agent being fed into the exhaust gas of the internal-combustion engine from a reducing agent tank internal to the vehicle. An electronic control device, by way of a signal of a sensor in the reducing agent tank, detects whether the reducing agent is in a frozen state. The electronic control device applies heating current to a PTC heating element in the reducing agent tank if the reducing agent is in a frozen state, calculates the resistance of the PTC heating element from the onboard voltage of the motor vehicle and the heating current, and compares the resistance with a first defined resistance threshold and/or with a first defined gradient threshold of the increase in resistance. The amount of reducing agent fed into the exhaust gas from the reducing agent tank is reduced if the first resistance threshold and/or the first gradient threshold is exceeded.

Abstract: A method is provided for the early induction of an additional start of an internal combustion engine in a vehicle with a hybrid drive including at least one electric drive unit and one internal combustion engine. When only the electric drive is in operation, then the internal combustion engine is additionally started no later than when the determined requested nominal drive torque exceeds the maximum possible drive torque of the electric drive unit. In order to initiate an additional startup of the internal combustion engine before reaching or exceeding the maximum possible drive torque of the electric drive unit by way of the requested nominal drive torque, the still unfiltered driver request torque or a limited driver request torque is evaluated.
