Abstract: <P>PROBLEM TO BE SOLVED: To validate the effects of the announcement of contact possibility by making an announcement under the consideration of actual conditions.  <P>SOLUTION: When an elapsed time after the change of a traffic lane is within a predetermined time (step S21), a threshold THW-Th for an inter-vehicle time is changed to a threshold Th-1 smaller than a threshold Th-0, and a control gain k-THW for the inter-vehicle time is changed to a coefficient k<SB>THW</SB>-1 smaller than a coefficient k<SB>THW</SB>-0 (step S23). In this case, the threshold THW-Th for the inter-vehicle time is set to regulate the start timing of the announcement of contact possibility, and the control gain k-THW for the inter-vehicle time is set to regulate the scale of a damping force as the announcement of contract possibility. Therefore, the above mentioned change is carried out since the change of the traffic lane until the lapse of the predetermined time so that the start timing can be delayed, and that the braking power can be weakened.  <P>COPYRIGHT: (C)2004,JPO
