Embodiment Construction

[0023] The collision avoidance system can be implemented in an integral vehicle-mounted manner, or it can have components located outside the vehicle. Therefore, for example, the provision of information related to roadside targets or other vehicles, the calculation of probability density, etc., can be implemented by roadside equipment instead of in the vehicle. Through examples, describe the solutions implemented in the vehicle.

[0024] figure 1 An example of a collision avoidance system in a vehicle (such as a car) is shown. The collision avoidance system includes an object detector 10, a data processor 12, a map storage device 14, a position detector 16, a speed detector 18, and an alarm Signal generator 19. The data processor 12 is connected to the target detector 10, the map storage device 14, the position detector 16, the speed detector 18, and the alarm signal generator 19.

[0025] The target detector 10 may be configured to detect the position and speed of other vehicle...

Abstract

Collision avoidance actions in a road vehicle are controlled based on a computed probability density of future positions of the vehicle. A preliminary probability density (32) is computed by means of a mechanical model by extrapolation from the detected state of the vehicle, including at least its detected position (31). Map data is used to define different regions in an area that contains the road, such as a first region that comprises a road part for traffic that moves in the direction of travel of the vehicle, a second region that comprises a road part for traffic in the opposite direction and a third region bordering on the road. The regions are used to obtain a correction factor of the computed probability density function in the first region (33). The correction factor is computed dependent on the aggregates of the probability density function in respective ones of the regions. In this way it is possible to compensate for errors that result from extrapolations that misinterpret swerving motion that suggest that the vehicle will move of the road, but are automatically corrected by the driver.

Description

Technical field [0001] The invention relates to a collision avoidance system for road vehicles (such as automobiles) and a collision avoidance method. Background technique [0002] US2003 / 55563 describes a collision avoidance method, which involves time-dependent probability density prediction for the location of vehicles and other road users. The observed probability distribution of current position, velocity, and acceleration is used to calculate the probability density of future positions. From the perspective of probability density, calculate the probability that the vehicle and other road users are located at the same time and at the same place. Events are triggered based on this probability (such as an alarm signal to the driver or automatic braking). [0003] J. [0004] Jansson and others have also described the use of probability density functions to avoid collisions in a large number of articles. For example, in 2008 Automatica ("Automation") from pages 2347 to 2351 call...
