摘要:
The present invention relates to a method for correction of a signal of at least one sensor, on the basis of which a path curve can be determined, on which the vehicle is moving, with the vehicle having a device by means of which the environment of the vehicle can be identified, and with the correction of the signal of the at least one sensor being carried out in that, at at least one point in time, the object location expected at at least one further point in time of an object which is identified as being stationary is determined on the basis of the vehicle speed and of the signal of the at least one sensor, and in that, at the at least one further point in time, the object location of the object which is identified as being stationary is recorded, with a correction of the signal of the at least one sensor being carried out on the basis of the discrepancy between the expected object location and the recorded object location.

A radome for a range warning radar system has metallic structures, such as a manufacturer's symbol or a characteristic structure, formed therein. Surfaces of the characteristic structure are coated with a metallic or metallically glossy layer which is transparent to electromagnetic radiation of the radar system and reflects visible light.

A method for displaying the impending danger due to speed associated with the driving situation of a vehicle and a display appliance for carrying out the method are described. In accordance with the method, a degree of danger is defined and calculated and displayed to the driver of a vehicle and, in fact, independently of whether the vehicle, as following vehicle, is driving too close to a vehicle in front or other obstacle (distance problem) or is driving too fast in fog (visual range problem). The signals necessary for this purpose are obtained from vehicle environment sensors, for example from a distance warning radar or distance recording radar and an infrared visual range measuring system, and are analyzed, together with vehicle condition signals, by a safety computer. On the basis of its specific programming, this computer determines and/or decides, for the respective current driving condition, which of the two degrees of danger is instantaneously predominant and indicates the condition which is respectively more critical to safety on a display. The display, as an indicating appliance, is produced in such a way that it makes it possible to recognize, in symbolic proportion, both the degree of difference between the instantaneous speed and the speed which is currently still safe and the current measure of the danger or freedom from danger in the manner of an analog display which reproduces trends.

摘要:
A method for determining the visual range improves the visual range measurement adopted as a basis, to the end that the measurement of the visual range can take place using one emitter and using one receiver, which are disposed to be stationary. The method permits the determination of the visual range, even though an obstacle is situated within the field of view. A comparison of a measured backscatter signal with a specimen curve permits the determination of the visual range from the intensity curve obtained, without any need, for this purpose, of further information such as, for example, the direction from which the backscatter signal comes.
