  • Patent number: 9714050
    Abstract: A collision avoidance assistance device configured to perform driver steering assistance to avoid a collision between a vehicle and an obstacle, the device includes a steering control unit configured to perform the steering assistance in a case where it is determined that there is a possibility of the collision between the vehicle and the obstacle. During a period from commencement of the steering assistance to elapsing of a first time determined by response characteristics of a lateral acceleration of the vehicle, the steering control unit is configured to rotate a steering wheel of the vehicle in a collision avoidance direction by a control amount determined based on a steering holding force of the driver.

  • Patent number: 9321484
    Abstract: A collision avoidance assistance device includes a target control amount calculation unit configured to calculate a target control amount used for travelling on a target trajectory through which the vehicle passes, a first control amount calculation unit configured to calculate a first control amount to be applied by the first steering assistance system out of the target control amount, and output the first control amount to the first steering assistance system, and a second control amount calculation unit configured to calculate a second control amount to be applied by the second steering assistance system out of the target control amount, and output the second control amount to the second steering assistance system. The first control amount is set to be larger than the second control amount during a predetermined time period from a time of starting the collision avoidance assistance.

  • Patent number: 8868325
    Abstract: A correct collision judgment is realized between an obstacle and a vehicle even when the vehicle enters a curve. In a collision judgment apparatus for judging the collision between the vehicle and the obstacle based on a relative positional relationship between a subject vehicle position of the vehicle and a relative movement straight line of the obstacle with respect to the vehicle as calculated based on a plurality of pieces of the position information acquired by a position information acquiring unit in relation to the obstacle, the relative positional relationship between the relative movement straight line and the subject vehicle position is adjusted so that a distance between the relative movement straight line and the subject vehicle position is separated if it is judged that the vehicle enters an entrance to a curve as compared with a situation in which the vehicle does not enter the entrance to the curve.

  • Patent number: 8849558
    Abstract: The present invention is intended to provide a technique which is capable of detecting a collision position of a moving object crossing a road and a subject vehicle with a higher degree of accuracy. In the present invention, in cases where the moving object crossing the road into which the subject vehicle has entered is detected at the time when the subject vehicle has turned to the right or to the left, the direction of a moving vector of the moving object is fixed to a direction which is set based on a shape of the road into which the subject vehicle has turned to the right or to the left. Then, the collision position of the moving object and the subject vehicle is predicted based on this moving vector of which the direction is fixed.
