  • Patent number: 7925415
    Abstract: In automatic steering control, when both a traveling lane and a preceding vehicle are detected, a target position on a first vehicle traveling path based on traveling lane information and a target position on a second vehicle traveling path based on preceding vehicle information are set as a first target position and a second target position, respectively. When the second target position is set farther than the first target position, the correction amount of the distance between the first target position and the second vehicle traveling path is set in accordance with the distance difference in the front-rear direction between the first and second target positions, and a third target position is set by correcting the first target position by the correction amount so as to become closer to the second vehicle traveling path. The steering control amount is calculated on the basis of the third target position.

  • Patent number: 7925413
    Abstract: A vehicle control system controls the speed of a vehicle according to actual road conditions and state of the vehicle. The control system acquires a present value of lateral acceleration occurring in a direction lateral to a controlled vehicle when the controlled vehicle avoids a collision with an obstacle or passes the obstacle. A target relative speed between the obstacle and the controlled vehicle is calculated from the present value of lateral acceleration and a turning radius of the controlled vehicle required for the controlled vehicle to avoid a collision with the obstacle or to pass the obstacle. Then, deceleration control is executed based on target relative deceleration rate at which the controlled vehicle is to be decelerated to reach the target relative speed.
