    Abstract: An anti-collision system detects conditions of an object preceding a source vehicle, and parameters indicative of operating conditions of the source vehicle, and controls the source vehicle so as to prevent a collision with the object, based on the detected conditions of the object and the detected operating conditions of the source vehicle. The system estimates a path of travel of the source vehicle, based on the detected parameters, and sets an area of travel of the source vehicle to a first predetermined area lying about the estimated path of travel. Further, the system estimates a path of movement of the object, based on the detected conditions of the object, and sets an area of movement of the object to a second predetermined area lying the estimated path of movement. The system calculates a possibility of collision, based on the set area of travel and area of movement, to thereby control the velocity of the source vehicle.

    Abstract: A system for controlling steering of a vehicle, including an electric motor used for power-steering torque assist control. In the system, the lane-keeping-steering assist torque TLK for causing the vehicle to run along the center of a road existing ahead of the vehicle is calculated, while the power-steering assist torque TPS for assisting the vehicle driver's steering is calculated. Then, ratios RTO1 and RTO2 are calculated based on the detected steering torque. The assist torques TLK, TPS are corrected by multiplication with the ratios RTO1, RTO2 respectively and are added together to determine a final assist torque TA, and based on the final assist torques TA, a motor current to be supplied to the electric motor is determined, thereby enabling to effectively prevent the two kinds of control from interfering with each other so as not to adversely affect the vehicle driver's perception of vehicle steering response. Additional ratios are determined based on the detected steering torque change and the vehicle speed.

    Abstract: An automatic travelling apparatus which permits: determination of a permissible travelling area on the basis of images taken by an image pickup device or video camera, showing the sight of the area appearing ahead of the vehicle; steering control of the vehicle to go into a target course in the permissible travelling area; and selection of a predetermined way of a selected crossing or branch in the target course.For the image pickup device or video camera taking images of the area extending ahead of the vehicle for determining a permissible travelling area, a wide-angle camera, a telescopic range camera and an ordinary camera are selectively used to meet particular situations for example, taking pictures of a crossing, zigzag way or straight long way. This selective use of cameras of different characteristics permits correct identification of particular roads with those stored in the map storage.

    Abstract: The invention carries out appropriate travel control so that a vehicle travels along recognized lane markings, and at the same time, prevents making the driver feel discomfort during travel control. In the case that the white line recognition becomes not possible, the delay time TD is shortened depending on a previous continuous time interval of a recognition state. In the case that the white line recognition flag becomes possible, the delay time TD is extended depending on the previous continuous time interval. In the case that the count value of the ON time measuring counter TON is equal to or greater than the delay time TD and the white line recognizing is possible, the compensation control is permitted, and reversion to the ON state of the travel control based on recognized white lines is permitted.
