PROBLEM TO BE SOLVED: To determine a travel direction of a vehicle with a simpler and highly reliable method.SOLUTION: A travel direction determination device includes: an acquisition section which acquires an output value of a vibration sensor for detecting vibration of front wheels and rear wheels of a vehicle; and a determination section which determines a travel direction of the vehicle on the basis of the output value of the vibration sensor, for instance. The determination section determines that the travel direction is an advance direction when vibration of the rear wheels is detected after vibration of the front wheels is detected and determines that the travel direction is a retreat direction when vibration of the front wheels is detected after the vibration of the rear wheels is detected.SELECTED DRAWING: Figure 2
【課題】車両の走行方向をより簡単でかつ信頼性の高い手法で判定する。【解決手段】実施形態による走行方向判定装置は、たとえば、車両の前輪および後輪の振動を検出する振動センサの出力値を取得する取得部と、振動センサの出力値に基づいて車両の走行方向を判定する判定部と、を備え、判定部は、前輪の振動が検出された後に後輪の振動が検出された場合、走行方向が前進方向であると判定し、後輪の振動が検出された後に前輪の振動が検出された場合、走行方向が後退方向であると判定する。【選択図】図2
