Abstract
In apparatus and method for automatically controlling a vehicular velocity of an automotive vehicle maintaining an inter-vehicle distance to a preceding vehicle, a follow-up run controller determines whether such a follow-up run control as to control the vehicular velocity should be released or not according to a vehicular motion when a shift lever of an automatic transmission shift mechanism (or of a continuously variable transmission) is operated to shift a drive (D) range to a gear maintaining range (such as a second-speed range or third- speed range). If the shift operation occurs from the drive range to the 2nd-speed range during the follow-up run control, the engine speed N2nd in the second-speed range is estimated. If the engine speed N2nd is equal to or lower than a predetermined threshold value N , the follow-up run control is continued. If the engine speed N2nd is in excess of the predetermined threshold value N , the follow-up run control is released.
