Vehicular velocity controlling apparatus for automotive vehicle

摘要

A vehicular velocity controlling section controls a vehicular driving force to make a detected value of the vehicular velocity (V) substantially equal to a set vehicular velocity (Vset). A first switch (SET/COAST switch) and a second switch (RESUME/ACCELERATE switch) are each enabled to be interlocked with a predetermined operation of at least one switching member (a lever or push buttons) at a position such as to match with a driver's sense of vehicular manipulation. A set vehicular velocity modifying section modifies the set vehicular velocity (Vset) in such a manner that the detected vehicular velocity (V) is set as the set vehicular velocity (Vset) when at least one of the following conditions is established: when the duration of the predetermined operation of the first switch is at least equal to a first predetermined duration, e.g. 350 msec, and the detected vehicular velocity (V) is lower than the set vehicular velocity (Vset); and when the duration of the predetermined operation of the second switch is at lest equal to a second predetermined duration, e.g. 350 msec, and the detected vehicular velocity (V) is higher than the set vehicular velocity (Vset). <IMAGE>
