Abstract
In method and apparatus for controlling a vehicular velocity of a host vehicle to follow a preceding vehicle which is running ahead of the host vehicle, a control target is switched between an inter-vehicle distance control in which the vehicular velocity of the host vehicle is controlled to make a detected value of the inter-vehicle distance substantially equal to a target value of the inter-vehicle distance and a vehicular velocity control in which the vehicular velocity of the host vehicle is controlled to make a detected value of the vehicular velocity of the host vehicle substantially equal to a target value of the vehicular velocity of the host vehicle according to a result of a detection of a variation of a gradient of a road segment which is forward of the vehicle and on which the host vehicle is to run.
