20080319589 | METHOD FOR DETERMINING A TILT ANGLE OF A VEHICLE - A method for determining a tilt angle of a vehicle includes measuring accelerations of a vehicle in directions along a longitudinal axis, a transverse axis, and a vertical axis of the vehicle. A current tilt angle of the vehicle is calculated as a function of the measured accelerations. A magnitude-compensated tilt angle is calculated as a function of the current tilt angle, of a preceding tilt angle, and of the magnitude of the vector sum of the measured accelerations. A gyroscopically stabilized magnitude-compensated tilt angle is calculated as a function of the current tilt angle, of a preceding tilt angle, of the magnitude of the vector sum of the measured accelerations, and of a change in the tilt angle over a given time period calculated from angular rate data provided by a gyroscope. | 12-25-2008 |
20090287408 | Method for Offering a User Reward Based on a Chosen Navigation Route - A method for offering a user reward based on a chosen navigation route includes calculating alternative routes from a starting location to a destination location by taking into consideration route segments including public transportation route segments and road network route segments. The alternative routes are presented to a user. A reward is offered for choosing a respective one of the routes. A navigation system that performs the route calculation preferably queries a network database for public transportation information. | 11-19-2009 |
20100014711 | Method for controlling an illumination in a vehicle interior in dependence on a head pose detected with a 3D sensor - A method for controlling an illumination in a vehicle interior includes the steps of collecting, with a 3D sensor, three-dimensional information about a driver and detecting the driver as an object in a three-dimensional space by processing the three-dimensional information about the driver. At least one three-dimensional driver characteristic, such as a head pose, a head position, a body position and a body posture, is determined. An area of attention of the driver is determined by evaluating the at least one three-dimensional driver characteristic. An illumination scheme for the vehicle interior is determined based on the area of attention of the driver such that vision conditions for the driver are improved. A method for detecting driver drowsiness and a method for controlling a visibility of display screen information in the vehicle interior are also provided. | 01-21-2010 |
20100014712 | Method for updating a geographic database for an in-vehicle navigation system - A method for updating a geographic database containing image data and road vector data to be used in vehicle navigation systems includes determining whether a vehicle is in an on-road position based on information provided by the vehicle navigation system. A geographically coded image is generated with a vehicle-mounted camera if the vehicle is not in an on-road position according to the information provided by the vehicle navigation system. The geographically coded image generated by the vehicle-mounted camera is analyzed in order to determine whether the geographic database requires updating. | 01-21-2010 |
20100017119 | NAVIGATION SYSTEM FOR A MOTOR VEHICLE - In a method for operating a navigation system for a motor vehicle having an offboard data memory, spatially separated from the motor vehicle, having data packets of visual map information, divided by region, as well as a display arranged in the motor vehicle, a selection of data packets provided for transmission to the motor vehicle and/or their sequence occur as a function of the resolution of the display, the location of the motor vehicle, an assumed route of the motor vehicle and/or the bandwidth of a communication connection provided for the transmission, the selected data packets being transmitted to the motor vehicle (e.g., in the selected sequence), and visual map information from data packets transmitted to the motor vehicle being represented by the display. | 01-21-2010 |
20100074555 | METHOD FOR PROCESSING A SATELLITE IMAGE AND/OR AN AERIAL IMAGE - In a method for processing a satellite image and/or aerial image, unwanted objects are able to be removed from the satellite image and/or aerial image. Geographical positions of objects pictured in the satellite and/or aerial image are determined, at least one photo is taken at ground level at each and/or in the respective immediate vicinity of the geographical positions determined, and these photos taken at ground level are superimposed on the satellite image and/or aerial image. | 03-25-2010 |
20100088093 | Voice Command Acquisition System and Method - A voice command acquisition method and system for motor vehicles is improved in that noise source information is obtained directly from the vehicle system bus. Upon receiving an input signal with a voice command, the system bus is queried for one or more possible sources of a noise component in the input signal. In addition to vehicle-internal information (e.g., window status, fan blower speed, vehicle speed), the system may acquire external information (e.g., weather status) in order to better classify the noise component in the input signal. If the noise source is found to be a window, for example, the driver may be prompted to close the window. In addition, if the fan blower is at a high speed level, it may be slowed down automatically. | 04-08-2010 |
