<p><P>PROBLEM TO BE SOLVED: To provide a running control device for the vehicle capable of properly identifying the foregoing vehicle to be followed and executing a stable following distance control. <P>SOLUTION: The running control device for the vehicle includes an interrupting vehicle determining part 8 which determines whether or not any other vehicle exists between the own vehicle and the foregoing vehicle to be followed according to the signals given by a radar sensing output part 2 and a foregoing vehicle determination part 7. If there is any other vehicle ahead, determination is made for the other vehicle about three conditions, whether the lateral relative movement to the own vehicle is in the approaching direction, whether the lateral relative travelling speed to the own vehicle is equal to or over the predetermined value, and whether the relative travelling speed in the advancing direction to the own vehicle concerned is equal to or over the predetermined value. If the other foregoing vehicle meets these three conditions, this is determined as an interrupting and run-off vehicle, and in case the distance and the relative speed between this vehicle and the own vehicle do not meet the specified conditions, the following distance control to the interrupting/run-off vehicle is not executed and a target vehicle speed correcting part 10 does not make the correction of the target vehicle speed determined for the foregoing vehicle being followed. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
