Beschreibung
Zusammenfassung:	A driving assistance device for a vehicle includes a front camera and an image processing ECU configured to detect a display object present forward of a vehicle and recognize display content of the detected display object, and a driving assistance ECU configured to execute driving assistance control for assisting a driver in a case where the display object is detected by the front camera and the image processing ECU. The driving assistance ECU sets an assistance level of the driving assistance control high when the detected display object is detected multiple times in the past, and a rate of coincidence of recognition results indicating the number of times determined to be the same display content to the number of detection times is equal to or greater than a first threshold value, compared to when the rate of coincidence of the recognition results is less than the first threshold value.
