Abstract
An adaptive vehicle speed control system includes a vehicle speed sensor detecting a vehicle speed of a host vehicle which is subjected to adaptive vehicle speed control including preceding vehicle following control and vehicle speed control, and an inter-vehicle distance sensor detecting an inter-vehicle distance between the host vehicle and a preceding vehicle. A man-machine interface is provided for setting a set vehicle speed. Also provided is an adaptive vehicle speed controller which includes a desired inter-vehicle distance arithmetic-processing section calculating a desired inter-vehicle distance based on at least the host vehicle speed, a following control section determining a desired speed of the host vehicle based on the host vehicle speed and the inter-vehicle distance so that the inter-vehicle distance is brought closer to the desired inter-vehicle distance in presence of detection of the preceding vehicle, and a vehicle-speed adjustment device which adjusts the host vehicle speed to the desired speed. The adaptive vehicle speed controller includes a vehicle speed setting section which sets the desired speed to a speed value higher than a low-speed threshold value whe…
