To provide a method of adjusting a vehicle display device that can efficiently adjust positional displacement in an image horizontal direction.SOLUTION: A method of adjusting a vehicle display device includes the steps of: performing first inspection on a vehicle display device 1, calculating a first correction value, and writing the same into a non-volatile memory 6; and performing second inspection, calculating a second correction value, and writing the same in the non-volatile memory. In the first inspection, the vehicle display device is installed on an inspection table 220 and projects an image on a windshield 200 for inspection, and the first correction value is calculated on the basis of positional displacement in an image horizontal direction when vertically changing a projection position of the image. In the second inspection, the vehicle display device projects an image on a windshield of a vehicle, and the second correction value is calculated on the basis of positional displacement in the image horizontal direction when vertically changing the projection position of the image. In the second inspection, a display device displays the image in which a display position is corrected with the first correction value.SELECTED DRAWING: Figure 3

    【課題】画像横方向の位置ずれを効率よく調整できる車両用表示装置の調整方法を提供する。【解決手段】車両用表示装置の調整方法は、車両用表示装置1に第一の検査を行なって第一補正値を算出し、不揮発性メモリ6に書き込む工程と、第二の検査を行なって第二補正値を算出し、不揮発性メモリに書き込む工程と、を含み、第一の検査では、車両用表示装置は検査台220に設置されて検査用のウインドシールド200に対して画像を投影し、第一補正値は、画像の投影位置を上下に変化させたときの画像横方向の位置ずれに基づいて算出され、第二の検査では、車両用表示装置は車両のウインドシールドに対して画像を投影し、第二補正値は、画像の投影位置を上下に変化させたときの画像横方向の位置ずれに基づいて算出され、第二の検査において、表示デバイスは、第一補正値による表示位置の補正がなされた画像を表示する。【選択図】図3
