摘要:
A vehicle information processing unit 16 collects vehicle information, which is information relating to the discharge amount of exhaust gas of at least one at any of a predetermined point, a predetermined section, and a predetermined period of time. An ecological traveling history DB 26 accumulates the vehicle information collected by the vehicle information processing unit 16 for each point through which the vehicle has traveled. A display device 30 displays the vehicle information accumulated in the ecological traveling history DB 26 by an image on a map including each point for each point through which the vehicle has traveled. Therefore, it becomes possible to allow a driver to recognize previous traveling performance at the point through which the vehicle has traveled, and to more effectively provide the driver with a guide or a motivation to perform ecological traveling, thereby providing a more useful in-vehicle apparatus which allows the driver to perform ecological traveling.
