A vehicle power indication status quantity display unit 16a displays on an indicator a vehicle power indication status quantity obtained by dividing the torque required for driving a hybrid vehicle by the upper limit value of the torque that does not excessively increase the fuel consumption. A HV eco zone 502 of the vehicle power indication status quantity display unit 16a is the zone that is determined by the upper limit value and the lower limit value of the HV eco zone that indicates the motor is being effectively used to drive the vehicle. A check is made to determine whether the vehicle power indication status quantity 505 is within the HV eco zone 502, and, if it is determined to be within the HV eco zone 502, the driving being performed is diagnosed as fuel-saving driving. For example, the ratio of the travel distance with the vehicle power indication status quantity 505 staying within the HV eco zone 502 to the one-trip travel distance is turned into a score, and an advice suitable for the score is presented to the driver. In this manner, the driver's awareness about fuel-saving driving at the time of acceleration and deceleration can be increased.
