DEVICE FOR PREDICTING IMPACT CAPABLE OF ENHANCING ACCURATE IMPACT PREDICTION BY RECOGNIZING OBSTACLES

摘要

PURPOSE: An impact prediction device is provided to improve the accuracy of an impact prediction by exactly recognizing front obstacles having the high impact possibility with a vehicle. CONSTITUTION: An impact prediction ECU(Electronic Control Unit) of an impact prediction device assumes the existence of front obstacles. The ECU assumes the existence based on road shape data from a navigation ECU of a navigation device(S14). The ECU revises a calculated inclined amount of a road(S15). The ECU revises the inclined amount based on road inclination data from the navigation ECU(S19). The ECU decides a gate passing of a vehicle(S21) by obtaining an ETC(Electronic Toll Collection) gate passing signal from the navigation ECU(S20). The ECU performs an impact prediction based on the revised value(S23). Thereby, the accuracy of the impact prediction is improved.
