Abstract: A signaling system provides at least one emergency services signal for fastening to a roof of a motor vehicle. The signaling system includes a housing that is directed in the travel direction and has a low aerodynamic resistance. The signaling system furthermore has a signaling unit that is disposed within the housing and is configured for providing emergency services signals. The housing has at least two housing sides, wherein one housing side faces the roof, and the other housing side faces away from the roof. The side that faces the roof is adapted to the shape of the roof. The housing side that faces away from the roof corresponds to the suction side of an airfoil profile.

Abstract: Methods and systems are provided for a coolant system. In one example, a method may include flowing coolant to an active cylinder during a cold-start.

Abstract: A cruise control system controls fuel supplied to an engine of a motor vehicle based in part on whether the vehicle is travelling on a positive gradient, a negative gradient, or a level surface. The system includes a sensor for detecting a position of an accelerator pedal of the vehicle, an inclinometer for detecting a gradient of a surface over which the vehicle is traveling; and an electronic processor operative to set a fuel flow rate. The fuel flow rate is set as a function of the accelerator pedal position detected at an activation time of the cruise control system, and that fuel flow rate is maintained at a constant rate if the vehicle is travelling on a positive gradient or a level surface. The vehicle therefore slows down on the positive gradient rather than maintaining a target speed as with a conventional cruise control system.

Abstract: A method for operating a motor vehicle having at least one sound sensor for detecting acoustic signals generated outside the vehicle includes the steps of detecting an acoustic signal by means of the sensor, classifying the detected acoustic signal as a warning signal if the detected signal has defined features, determining the speed of the vehicle, determining the steering angle of the vehicle, defining an action to be carried out by the motor vehicle in response to the detected warning signal, and carrying out the defined action if the speed of the motor vehicle undershoots a defined threshold value and the steering angle of the vehicle exceeds a defined threshold value. The defined action may be a steering and/or braking maneuver by the vehicle, and/or may be alerting a driver of the vehicle.

Abstract: A heat accumulator for a vehicle engine, comprising storing coolant in a flexible storage container with an inner body and an outer body, with an insulation device arranged between the bodies, and an inflow and an outflow for the coolant wherein the storage container can expand and deflate in response to the amount of coolant stored. The flexible storage container allows for the heat accumulator to conform to various under hood space constraints.
