Vehicle spacing control system

摘要

When a selected vehicle-to-vehicle time gap (To) is changed from a first level to a second level with a selector switch (5; 5A), a controller (11) determines a desired time gap (T*) or spatial gap so that the desired gap varies from the first level to the second level at such a gradual rate as to prevent an abrupt change in the vehicle speed. The controller (11) determines a desired vehicle spacing (L*) from the controlled vehicle to a preceding vehicle in accordance with the desired time gap (T*) and a sensed vehicle speed (V), and controls the driving or braking force so as to bring the actual vehicle spacing (L) closer to the desired vehicle spacing (L*).
