In a collision warning device that includes an information processing circuit that issues a warning signal when it is determined that there is a risk of a rear-end collision, the information processing circuit is configured to issue a warning signal within a predetermined time after a sudden change in the inter-vehicle distance R with respect to the preceding vehicle. , or when the inter-vehicle distance R is smaller than a predetermined value _R0 , the following formula VaTd+Va ² -(Va+ddtR) ² 2α
≧R (where Va: own vehicle speed, Td: driver's response delay time, α: deceleration due to own vehicle's braking) is established and a danger signal _D1 is generated to prevent a collision. A collision warning system featuring:
