Object collision warning system and method for a motor vehicle

摘要

An object collision warning system for a motor vehicle comprises a sensing means (11) adapted to sense a surrounding of the motor vehicle and a processing means (14) adapted to detect objects in a surrounding of the motor vehicle by processing a signal provided by the sensing means (11), to perform an estimation of a collision probability between the vehicle and the detected object, and to output a corresponding signal in case the collision probability is non-negligible. The processing means (14) is adapted to determine, after having passed a curve, information describing the passed curve, to store the curve describing information, and to use the curve describing information of at least one previously passed curve for determining the vehicle path in a current curve in the estimation of the collision probability.

1. An object collision warning system for a motor vehicle, comprising
a sensing means for sensing a surrounding of the motor vehicle and a processing means for detecting objects in a surrounding of the motor vehicle by processing a signal provided by the sensing means, performing an estimation of a collision probability between the vehicle and the detected object, and outputting a corresponding signal in case the collision probability is non-negligible, the processing means distinguishing between a straight path and curves and further for determining, after the motor vehicle having passed a curve, information describing the passed curve, storing the curve describing information as curve variables, and using the curve describing information of at least two previously passed curves for determining the vehicle path in a current curve in the estimation of the collision probability, wherein only the curve information of different curves is weighted in the estimation of the collision probability and wherein the curve information of previously passed curves is weighted differently for different previously passed curves, a means for estimating when the vehicle has passed half of a curve, and a means for outputting a signal at least to a driver of the motor vehicle as a warning signal or to a safety device as a control signal in case the collision probability is non-negligible.
