    摘要: A method of determining a safe distance (dsafe) between a first vehicle (1) and a second vehicle (2) moving ahead of the first vehicle, each vehicle having a state which comprises at least one of a position (s1, s2), a speed and an acceleration of the respective vehicle, the method comprising the steps of:—collecting sensor data relating to the state of the vehicles (1, 2),—determining, using the sensor data and a time-dependent description of the state of the second vehicle (2), a state of the second vehicle (2) as a result of a maximum deceleration of said second vehicle,—determining, using a time-dependent model of the behaviour of the first vehicle (1) and said state of the second vehicle (2), a state of the first vehicle (1) as a result of said maximum deceleration of said second vehicle (2), and—determining, using said state of the second vehicle (2) and said state of the first vehicle (1), the safe distance (dsafe). Said state of the second vehicle (2) and said state of the first vehicle (1) involve uncertainties introduced by the sensor data, thus increasing the safety margin of the method.

    摘要: 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.
