Abstract:
An on-vehicle emergency report apparatus comprising vehicle position detection means for detecting the position of a vehicle, emergency situation prediction means for predicting that the vehicle encounters an emergency situation, and communication means for communicating with an emergency report service station,wherein: the emergency situation prediction means predicts whether the vehicle would encounter an emergency situation after a predetermined period of time, based on at least one of the distance from the vehicle to an object with which the vehicle may collide, the relative speed, the relative acceleration, the speed, and the brake pedal stroke, the steering wheel angle and the facial expression of the driver of the vehicle; said emergency situation prediction means predicts the position of the vehicle and the position of said object with which said vehicle may collide, as of the predetermined period time later, based on the distance between said vehicle and said object, and the speed, the acceleration and the steering wheel angle of the vehicle, and estimates a possibility of collision based on the predicted positions of said vehicle and said object; and an estimated result is transmitted to said emergency report service station by said communication means, together with vehicle position information detected by the vehicle position detection means.
