To provide a road-vehicle cooperation positioning method which achieves highly accurate positioning of a vehicle in the case of being unable to receive a satellite signal and has a small installation number of facilities, low cost and a simple method, a device, an electronic facility, a storage medium, an automatic driving vehicle, and a program.SOLUTION: Broadcast information transmitted by a roadside unit is received. The broadcast information includes: a transmission time, the height of a roadside unit, and position information of the roadside unit; the calculation of a horizontal distance between the vehicle and the roadside unit on the basis of a reception time of the broadcast information, the transmission time and the height of the roadside unit; and the acquisition of the position information of the vehicle by matching the horizontal distance between the vehicle and the roadside unit and the position information of the roadside unit with map information.SELECTED DRAWING: Figure 1

    【課題】衛星信号を受信できない場合に車両の高精度測位を実現し、設備の設置数量が少なく、コストが安く、方法が簡単な路車協調測位方法、装置、電子設備、記憶媒体、自動運転車両、及びプログラムを提供する。【解決手段】路側ユニットより送信されたブロードキャスト情報を受信することであって、ブロードキャスト情報は、送信時間、路側ユニットの高さ、路側ユニットの位置情報を含むことと、ブロードキャスト情報の受信時間、送信時間及び路側ユニットの高さに基づいて、車両と路側ユニットの水平距離を計算することと、車両と路側ユニットの水平距離及び路側ユニットの位置情報を地図情報とマッチングして、車両の位置情報を得ることとを含む。【選択図】図1
