Abstract: A fuel cell device of a motor vehicle is disclosed. The fuel cell device includes a fuel cell, a supply air path leading to the fuel cell for a cathode supply air flow, and an exhaust air path leading away from the fuel cell for a cathode exhaust air flow. The supply air path and the exhaust air path are routed through a humidifier that humidifies the supply air and dehumidifies the exhaust air. The exhaust air path is further routed through a water separator that removes water from the exhaust air to provide evaporation water. A heat exchanger for cooling the fuel cell is provided that has an evaporative cooler for cooling the heat exchanger. The evaporative cooler is assigned to the water separator in fluidic communication and is supplied with evaporation water by the water separator.

An actuator unit can then execute the lane changes calculated by the arithmetic and logic unit and initiated by the vehicle driver upon receipt of a signal from the arithmetic and logic unit.

Abstract: A driver assistance system and an operating method thereof are configured and adapted to perform autonomous longitudinal and/or lateral control of a vehicle. At least one control task for longitudinal and/or lateral control of the vehicle can be transferred from the driver to the driver assistance system. This involves informing the driver that a control task can be transferred to the system, and then transferring the control task from the driver to the system in response to the driver ceasing a manual control of this control task.

Abstract: The present invention relates to a method and device for reducing instances of vehicle collisions. Based on parameter data of a first vehicle and road conditions, and parameter data regarding a second vehicle, the first vehicle can undergo warnings or positional adjustments to reduce the likelihood of a collision with the second vehicle or other collision body. The vehicle adjustment can be in the form of braking or steering adjustments. The warning can be in the form of a visual, audio, or haptic signal.

Abstract: A method for the automated braking and/or steering of a vehicle uses at least one sensor system for detecting the vehicle's surroundings, a potential collision object in the vehicle's surroundings, and a relative speed of the vehicle relative to the potential collision object. The activation and/or the sequence of an automated steering intervention and/or an automated braking intervention is determined based on the relative speed. The braking intervention is activated at first when the relative speed is below or equal to a predefined threshold, and the steering intervention is activated at first when the relative speed is above the predefined threshold.

Abstract: In a method for determining a course of a traffic lane for a vehicle (10), structures that demarcate a trafficable space are detected in image data from an image acquisition unit (2), and these structures are plotted on a surroundings map (20) that subdivides the surroundings of the vehicle into a two-dimensional grid (20a) of cells (21). The position of the vehicle in the grid of the surroundings map is determined and updated by odometric data. The distance and the direction of the vehicle (10) relative to those cells (21b) of the grid (20a) having structures that demarcate the pavement and/or the traffic lane are determined. Brightness transitions in the image data are detected and are plotted on the cells (21) of the grid (20a). The course of the traffic lane (22) is determined from the cells with the detected brightness transitions.

Abstract: The invention relates to a method for creating a current situation depiction, particularly a current city-centre situation depiction, in which environment data and/or map data and/or position data describing a locally bounded situation are sent to a database by a multiplicity of vehicles using vehicle-to-X communication means. The environment data are captured by means of ambient sensors and/or vehicle sensors, the map data are read from a digital memory, and the position data are determined at least by means of a global satellite position system. The method is distinguished in that the environment data and/or the map data and/or the position data are continually merged with a situation depiction that is already present in the database to form a current situation depiction, and both the database and the situation depiction are fixed in location. The invention also relates to an appropriate system.

Abstract: A device for assisting a driver driving a vehicle or for autonomously driving a vehicle includes several distance sensors (2, 4, 5) and camera sensors (1, 3), an evaluation unit, and a control unit. The distance sensors detect objects that are directly in front of and behind the vehicle. The camera sensors cover an area surrounding the vehicle. From the data of the distance and camera sensors, the evaluation unit determines a three-dimensional representation of the areas covered by the sensors. Taking the three dimensional representation into account, the control unit generates a piece of advice for the driver or intervenes in vehicle steering.
