Abstract: PROBLEM TO BE SOLVED: To provide a driving assistance system allowing improvement of mileage performance of a vehicle for following travel control. SOLUTION: This driving assistance system 1 allows the following travel control controlling a vehicular gap between one's own vehicle and a proceeding vehicle to a prescribed target vehicular gap and vehicle speed maintenance control controlling a vehicle speed of the own vehicle to a prescribed target vehicle speed. The driving assistance system 1 includes: a speed fluctuation decision means 32 deciding speed fluctuation of the proceeding vehicle; the proceeding vehicle speed acquisition means 23 acquiring a vehicle speed of the proceeding vehicle; and a target vehicle speed resetting means 33 resetting the target vehicle speed of the own vehicle. When it is decided that the speed fluctuation of the proceeding vehicle is larger than a prescribed threshold value, the following travel control is suspended or stopped. The target vehicle speed of the own vehicle is reset based on the vehicle speed of the proceeding vehicle, and the vehicle speed maintenance control is performed. COPYRIGHT: (C)2010,JPO&INPIT
