摘要:
In a method and apparatus for radio-based issuing of warnings of hazards to the driver of a vehicle having a data receiver, the data receiver receives data from at least one data transmitter of at least one other vehicle, and evaluates the received data. The received data comprising information about the position, speed and direction of travel of the transmitting vehicle. The approach speed between the receiving vehicle and transmitting vehicle are determined in order to evaluate the received data in the receiving vehicle. According to the invention, in order to evaluate the received data in the receiving vehicle, the distance between the transmitting vehicle and the receiving vehicle is determined, and it is determined whether information is output to the driver, based on the distance between the transmitting vehicle and receiving vehicle, and based on the approach speed between the transmitting vehicle and receiving vehicle.

The invention relates to a method and device for supporting the driver of a vehicle during an emergency braking process in order to prevent the vehicle from colliding with an object which is located in a detection zone in front of the vehicle in the direction of travel, in particular a preceding vehicle. In the method according to the invention braking means for braking the vehicle (50) are actuated independently of the driver if a predefined emergency braking condition is met and if it is determined that the driver wishes to carry out the emergency braking process, emergency braking information to the driver of the vehicle (50) being issued when the emergency braking condition is met. According to the invention information to the driver is issued even when the emergency braking condition is not met, said information informing the driver of the vehicle (50) about the current situation in the surroundings or the traffic situation in the detection zone (54), the information to the driver being adjusted as a function of predefined information conditions being met.
摘要:
An elastic sealing element in the form of bellows, which is used to seal the contact surface between at least two components movable in relation to one another is described, which has low-elasticity contact zones as well as a deformation zone whose elasticity is higher than that of the contact zones, wherein the said deformation zone defines a chamber for accommodating lubricants on its inner side facing the movable components. An overpressure relief means (14) is arranged at least in the area of one of the two low-elasticity contact zones (6 or 7). The overpressure relief means (14) has at least one relief opening (15) connecting the lubricant chamber (11) with the outside of the sealing element (1) and a closing element (16) covering the said relief opening. The closing element (16) is in turn made in one piece with the sealing element (1) and closes the relief opening (15) up to an overpressure limit in the lubricant chamber (11) due to the intrinsic elasticity of the material of the sealing element.
