To address the problem of realizing an effective travel assisting function for an electric car, with a prediction risk taken into account.SOLUTION: An electric car travel assisting device of the present embodiment is installed on a road side in order to assist an electric car in traveling, the travel assisting device being constituted by comprising information acquisition means, parameter learning means, prediction risk calculation means and arrival probability calculation means. The information acquisition means acquires travel-associated element information including gradient information, weather information, congestion information and electric car remaining battery life from a charge information server installed on road side. The parameter learning means learns a plurality of parameter coefficients of an electricity consumption estimation model using the travel-associated element information. The prediction risk calculation means calculates the average value of electricity consumption and the standard deviation of electricity consumption of the electric car in a travel section on the basis of the element information and the electricity consumption estimation model. The arrival probability calculation means calculates arrival probability in the travel section on the basis of the remaining battery life and the calculation result of the prediction risk calculation means.SELECTED DRAWING: Figure 2

    【課題】予測リスクを考慮した効果的な電気自動車の走行支援機能を実現するという課題がある。【解決手段】本実施形態の電気自動車の走行支援装置は、電気自動車の走行を支援するために、路側に設置された走行支援装置であって、情報取得手段と、パラメータ学習手段と、予測リスク計算手段と、到達確率計算手段とを有する構成である。情報取得手段は、勾配情報、気象情報、渋滞情報、及び電気自動車の電池残量を含む走行関連の要素情報を、路側に設置された充電情報サーバから取得する。パラメータ学習手段は、走行関連の要素情報を使用して、電費推定モデルの複数のパラメータ係数を学習する。予測リスク計算手段は、要素情報、及び電費推定モデルに基づいて、走行区間において電気自動車の電費の平均値と電費の標準偏差を算出する。到達確率計算手段は、電池残量及び予測リスク計算手段の算出結果に基づいて、走行区間での到達確率を算出する。【選択図】図2
