When finding the driver distracted from driving (such as looking aside), this system provides driving assistance that enhances his or her motivation to drive by encouraging him or her to drive actively and thereby increase his or her internal focus on driving. Examples of specific driving assistance include giving exemplary driving instructions to the driver, providing him or her with navigation to a road with features that would entertain him or her through driving, and improving sensitivity to any change in the vehicle's state responsive to driving operations. If dangerous driving is sensed while the driving assistance is being provided, driving control may be performed to increase the driver's tension.
