Driving support device

A driving support device comprising:

• a steering wheel operated by a driver for steering a steered wheel of an own vehicle;
• a camera, including a protection window, for photographing a surrounding region around the own vehicle through the protection window to acquire image data;
• a display unit for displaying a screen including an image based on the acquired image data by the camera;
• a driving support unit for having the display unit display the screen so as to support driving of the driver;
• and
• a washer for washing the protection window,
• wherein
• the driving support is configured to:
• have the washer wash the protection window for a predetermined time period, when a magnitude of a steering angle of the steering wheel from a neutral position changes a value smaller than a threshold wash angle to a value equal to or greater than the threshold wash angle;
• have the display unit start a display of a turn screen including an image corresponding to a predetermined region which the driver needs to pay attention to while the own vehicle is turning and which is a part of the surrounding region, when the magnitude of the steering angle changes from a value smaller than a threshold display angle which is greater than the threshold wash angle to a value equal to or greater than the threshold display angle;
• and
• have the display unit terminate the display of the turn screen, when the magnitude of the steering angle changes from a value greater than a threshold termination angle to a value equal to or smaller than the threshold termination angle while the display unit is displaying the turn screen.
