Abstract
In automatic vehicular velocity controlling apparatus and method for automotive vehicle having a function to maintain an inter-vehicle distance from the vehicle to a preceding vehicle which is running ahead of the vehicle at a target inter-vehicle distance, a response characteristic of an inter-vehicle related feedback control system is determined in accordance with a relative velocity of the vehicle to the preceding vehicle is corrected in accordance with the inter-vehicle distance, is corrected in accordance with a modification of a set inter-vehicle time duration by a vehicular occupant, and in accordance with an external disturbance value correspond to a road surface gradient of a slope during a vehicular run on the slope, in order to improve the response characteristic for the vehicular occupant not to give an un-match feeling to a driving sense.
