A vehicle speed acquisition unit acquires speed information indicating a vehicle speed. An output acquisition unit acquires output information indicating an output of a drive unit that drives the vehicle. An output rate derivation unit derives an output rate indicating a ratio of the output to a rated output of the vehicle at the current vehicle speed. A waste derivation unit derives waste information indicating a degree of waste of energy consumed by the vehicle. A display unit displays a waste status of the energy. When the speed is within a predetermined speed range and the output rate is within a preset first output range, the waste derivation unit derives the waste information indicating that the waste of energy when the speed is high is less than when the speed is low, even when the output rate is the same. |
