PROBLEM TO BE SOLVED: To allow a driver to grasp a temporal allowance for performing operation of a right turn or a course change, to raise awareness of safe driving, and to improve the skill of the driver inexperienced in driving. SOLUTION: A driving operation detection means, on detecting the course change of an own car, transmits course change information to a driving operation support control means, which selects/activates an approaching object detection means according to the course change information. The approaching object detection means detects a car approaching to the own car on an adjacent lane which the own car will enter by the course change, and transmits results of measurement of the distance therefrom and the relative speed to the driving operation support control means. The driving operation support control means calculates a time period until the approaching car reaches a predetermined position where the own car will pass through due to the course change on the basis of the received distance and relative speed, and transmits the calculation result to a notification means. In addition, the driving operation detection means transmits the measured steering angle and car speed of the own car to the driving operation support control means, which then finds a time period required for the course change, and transmits diagnosis result information based on the relationship between the time period and arrival time to the notification means.
