1. A vehicle traveling information recording device comprising:

  • a fuel economy gauge;

    a traveling information detection unit;

    a control unit for using the traveling information detection unit to classify fuel economy information of the fuel economy gauge, the control unit distinguishing the fuel economy information of the fuel economy gauge for a first state of travel at constant speed over flat ground, which is a unique combination of a constant speed and a flat ground, from a second state of travel with acceleration or deceleration over flat ground and from a third state of travel at constant speed over an up or down slope; and

    an analyzer of driving technique configured to extract the fuel economy information for the second and third states and to exclude the fuel economy information for the first state which is unaffected by the driving technique and in no use for analyzation by itself, wherein the extracted second and third states are used for analyzation of driving technique of acceleration or deceleration and travelling over up or down slope, respectively,whereby the fuel economy information affected by the driving technique is effectively extracted from profusion of information without disturbance by the fuel economy information unaffected by the driving technique,wherein the vehicle traveling information recording device further comprises;

    a notification unit for providing notification on the basis of information of the traveling information detection unit, anda timing control unit for controlling timing of notification performed by the notification unit.
