Vehicle following control with inhibition of braking action on loss of target

摘要

A vehicular velocity controller includes a calculating section that calculates a target inter-vehicle distance (L*) from the controlled vehicle to a preceding vehicle on the basis of a vehicular velocity (VS) detected by a velocity detector and an inter-vehicle distance (L) detected by a distance detector. A vehicular velocity controlling section performs velocity control to bring the detected inter-vehicle distance (L) substantially coincident with the target inter-vehicle distance (L*). A vehicular deceleration stopping section performs deceleration control to stop the controlled vehicle in accordance with the inter-vehicle distance (LO) pertaining immediately before the distance detector has ceased to detect the preceding vehicle when the detected vehicular velocity (VS) falls in a low vehicular velocity region lower than a predetermined velocity value while the distance detector does not detect the presence of a preceding vehicle.
