Abstract: Methods and systems are provided for operating a driver assistance system of a vehicle. A plurality of partially automated functions are performed using the driver assistance system during operation of the vehicle. In the partially automated functions, longitudinal guidance and/or transverse guidance of the vehicle are and/or is regulated, and/or information that describes surroundings of the vehicle is output and/or a signal is output to the surroundings using the driver assistance system. Following a predetermined number of performed partially automated functions, a moderation signal is output to a driver of the vehicle for a following function that can be performed in a partially automated manner using the driver assistance system. When the moderation signal is output, the driver is asked for feedback regarding the following function.

Abstract: A component for a vehicle that can be operated with a combustible operating gas has a first component element which has or forms an at least partially open or free cavity, and a second component element which is designed as a displacement component and at least partially fills the cavity of the first component element.

Abstract: An absorber device for electromagnetic sensor systems has at least one aperture. Each aperture is able to be opened and closed by an aperture closure. The absorber device is designed in such a way that when the aperture is open, electromagnetic waves incoming through the aperture do not then leave the absorber device, and when the aperture is closed, electromagnetic waves impinging on the aperture are reflected.

Abstract: A method for reducing the potential hazard of a number of vehicles with heterogenous drives includes receiving on a backend server hazard data of the vehicles which includes current fill state data of at least one energy store and the current position of the respective vehicles, identifying on a backend server hazard situation data comprising the position and the type of the hazard situation, evaluating on the backend server the hazard data of the vehicles with respect to the hazard situation data, and automatically initiating at least one protective measure corresponding to the evaluated hazard data.

Abstract: A pressure vessel arrangement has a pressure vessel for storing a gaseous fuel and a conducting arrangement arranged adjacent to the pressure vessel for conducting and weakening a shock wave occurring upon bursting of the pressure vessel. The conducting arrangement forms a chamber space that can be expanded by the shock wave. The conducting arrangement has an inlet into the space facing the pressure vessel, via which the shock wave enters the space and expands the space, and wherein the conducting arrangement has at least one outlet out of the space, via which the shock wave exits the space into the environment.

Abstract: A method monitors a pressure tank system of a stationary vehicle. The method detects a wake-up situation by use of sensor data of a main sensor of the vehicle. Furthermore, in reaction to the detection of a wake-up situation, the method activates a further resource for detecting and/or for evaluating sensor data with regard to the pressure tank system. Moreover, the method determines, by use of the further resource, whether one or more protective measures are to be carried out in relation to the pressure tank system and/or the surroundings thereof.

Abstract: A thermally activatable safety valve has at least one microwave transmitter and microwave transmitter component. The microwave transmitter and/or the microwave transmitter component is designed to heat at least one thermally activatable opening element.

Abstract: A method for cooling a first cryogenic pressure vessel, where the first cryogenic pressure vessel is designed for the storage of cryogenic gas, includes firstly conducting gas through the first pressure vessel for the purposes of cooling the first pressure vessel and subsequently feeding the gas to a second pressure vessel for the purposes of storing the gas, until the temperature of the first pressure vessel has reached a predetermined temperature value or until the second pressure vessel has reached a predefined degree of filling with gas.

Abstract: A method is provided for refueling a cryogenic pressure vessel of a motor vehicle. The motor vehicle has: a) a cryogenic pressure vessel having an internal vessel which stores a fluid, an external vessel and heat insulation which is arranged between the internal vessel and the external vessel, at least in certain areas; and b) a controller, wherein the controller is designed to interrupt refueling of the motor vehicle if, in the case of damaged thermal insulation, a lower fluid density limiting value for the fluid in the internal vessel is exceeded. The lower fluid density limiting value is lower than an upper fluid density limiting value for the fluid in the internal vessel in the case of refueling of the internal vessel with intact thermal insulation.

Abstract: A system for storing a pressurized gas in a motor vehicle is provided, having a storage container and at least one thermally activatable safety valve for emptying the storage container. The safety valve activates automatically at a corresponding high temperature. The storage container has an additional activatable emptying device, which has an interface for an external energy source. The interface can be connected to the external energy source in order to empty the storage container in a targeted manner. Also provided is a method for emptying a storage container for a pressurized gas in a motor vehicle.

Abstract: A safety device is provided for a pressurized gas tank in particular of a motor vehicle. The safety device has a thermoelectric device provided on a larger surface area of the tank, which thermoelectric device makes electrical energy available under the effect of heat. The safety device, in a suitable design of the system, controls either directly or indirectly a pressure-relief device of the tank in order to avoid heat-related damage to the tank. The thermoelectric device is formed by a plurality of interconnected thermoelectric generators, the electrical energy of which produced by the effect of heat is supplied to at least one capacitor. The two electrodes of the capacitor are connected to each other via a discharge resistor. The system is designed such that a defined power differential between the power produced by the thermoelectric generators and the power dissipated by the discharge resistor results in the control of the pressure relief device either directly or indirectly via a relay circuit.
