Abstract
In a collision prevention system, a control device defines a collision danger level X such that larger values indicate increased possibility of a following vehicle colliding into a host vehicle due to behavior of the host vehicle, and defines a proximity Pr such that larger values indicate shorter inter-vehicle distance or greater relative velocity between the host vehicle and the following vehicle. When a change in amount ΔX/Δt of the collision danger level X and a threshold value Kxa have a relationship Kxa≤ΔX/Δt, the control device changes a first threshold value Kpr of the proximity Pr to a second threshold value Kpr' lower than the first threshold value Kpr, and actuates a warning device when the collision danger level X and the threshold value Kx have a relationship Kx≤X and the proximity Pr and the second threshold value Kpr′ have a relationship Kpr′≤Pr.
