Abstract (en)

[origin: WO9930183A1] The present invention relates to a method and a device for predicting the existence of a curve in a road portion in front of a vehicle in connection with the utilisation of a radar arranged on the vehicle which, by transmitting a radar signal and recording received reflections thereof, provides information indicating the position of objects located in an area in front of the vehicle. According to the invention, values are derived which represent directions of hypothetical lines between said objects and from said directions are derived the corresponding values each of which defines the position of a respective one of said lines between said objects. Subsequently, it is determined whether at least a subset of said values of directions and corresponding positions fulfils a functional relationship between direction and position, whereby the existence of said curve is predicted on the basis thereof.
