Abstract
Warning apparatus for an automotive vehicle, operable to generate a warning signal when a distance between the vehicle and an object in front of the vehicle is shorter than a predetermined threshold value, the apparatus including a characteristic-value storage portion which stores at least one characteristic-value relationship between at least two of a plurality of brake operating characteristic values relating to a braking operation by an operator of the vehicle to brake the vehicle, and a threshold-value determining portion operable to determine the threshold value of the distance, on the basis of at least one of an estimated braking state of the vehicle estimated on the basis of the characteristic-value relationship stored in the characteristic-value storage portion, a running-state quantity indicative of a running state of the vehicle, and a moving-state quantity indicative of a moving state of the object.
