To provide an onboard device with which, when retrofitted to a vehicle, it is possible to appropriately determine the regression of the vehicle without acquiring a signal, such as a shift position signal of the vehicle, from various devices of the vehicle.SOLUTION: Provided is an onboard device retrofitted to a vehicle, comprising: a position acquisition unit for acquiring the position information of the vehicle; a speed calculation unit for calculating the speed of the vehicle using the position information of the vehicle acquired by the position acquisition unit; an acceleration measurement unit for measuring acceleration in the front-back direction occurring to the vehicle; and a regression determination unit for determining the regression of the vehicle on the basis of the vehicle speed calculated by the speed calculation unit and the acceleration in the front-back direction occurring to the vehicle that is measured by the acceleration measurement unit.SELECTED DRAWING: Figure 1
【課題】車両に後付けされる場合に、車両のシフトポジションの信号など、車両の各種装置からの信号を取得しなくても、車両の後退を適切に判定することができる車載機を提供すること。【解決手段】車両に後付けで搭載される車載機であって、前記車両の位置情報を取得する位置取得部と、該位置取得部で取得した前記車両の位置情報を用いて、前記車両の速度を算出する速度算出部と、前記車両に生じる前後方向の加速度を測定する加速度測定部と、前記速度算出部で算出された前記車両の速度と、前記加速度測定部で測定された前記車両に生じる前後方向の加速度とに基づいて、前記車両の後退を判定する後退判定部とを備えている。【選択図】図1
