To provide a road surface drawing device for a vehicle and a road surface drawing method for the vehicle capable of suppressing confusion between a mark or a line on a road surface and a projected image even when the image is projected to the rear of the vehicle in a backward operation or a parking operation.SOLUTION: Provided is a road surface drawing device for a vehicle that projects an image based on a drawing pattern onto a road surface, including: a road surface drawing part that projects an image by irradiating a road surface with light; a control part that controls projection of the image by the road surface drawing part; and an operation state acquisition part that acquires an operation state of the vehicle, wherein the control part, when determining that the operation state is the backward operation, controls the road surface drawing part in a backward operation mode, and, when determining that the operation state is not the backward operation, turns off the road surface drawing part.SELECTED DRAWING: Figure 5

    【課題】後退動作時や駐車動作時において車両の後方に画像を投影しても、路面上のマークや線と投影された画像の混同を抑制することが可能な車両用路面描画装置および車両用路面描画方法を提供する。【解決手段】描画パターンに基づく画像を路面に投影する車両用路面描画装置であって、路面に光を照射して画像を投影する路面描画部と、路面描画部による画像の投影を制御する制御部と、車両の動作状態を取得する動作状態取得部とを備え、制御部は動作状態が後退動作であると判定した場合には路面描画部を後退モードで制御し、動作状態が後退動作でないと判定した場合には路面描画部を消灯する車両用路面描画装置。【選択図】図5
