PROBLEM TO BE SOLVED: To permit following travel coinciding with the degree of congrestion by changing the responsiveness of a sensor in accordance with the degree of congestion of a road. SOLUTION: Vehicular gap data and self-vehicle speed are fetched, road type data is also fetched (step S 1), the degree of congestion of a road is estimated on the basis of the data (step 82), and whether or not the degree of congestion changes is decided (step 83). In the case the decision result is YES, the data filter sensitivity of a vehicular gap sensor 1 is adjusted in accordance with the height/lowness of the degree of congestion (step 84), vehicular gap data is filtered by a filter sensitivity at that time (step 85), and subsequently, whether the vehicular gap is larger or smaller than a preliminarily defined target vehicular gap distance is decided (step S6). When the vehicular gap is smaller than the target vehicular gap distance, deceleration control of the self- vehicle is performed and when the vehicular gap is larger, acceleration control is performed (step S7). |
