Abstract
A hybrid vehicle has as a travel mode an EV mode for traveling while stopping the engine, and an HV mode for operating the engine. An ECU includes first and second traveling distance operating units, and a determination unit. The first traveling distance operating unit calculates an EV traveling distance indicative of a total traveling distance in the EV mode. The second traveling distance operating unit calculates the engine use traveling distance indicative of a total traveling distance when the engine is operated. The determination unit determines the necessity of maintenance of predetermined elements included in the vehicle based on the EV traveling distance and the engine use traveling distance.
