Abstract: Fail operational that can guarantee stability of control while suppressing cost increase is difficult. A control controller according to the present invention stores information necessary for recovery in a normal travel mode in time series in a backup, and thus control software can be recovered from the backup in real time if a failure occurs in the system.

Abstract: A navigation system for an electric vehicle includes a telematics center, a display terminal, and a charging station. In response to a request from the display terminal, the telematics center sends a route search result, which is created based on information on an electric vehicle and the charging station and which includes base point information whose remaining battery capacity is to be confirmed, to the display terminal. The display terminal displays route guidance information, the current position, and a result of comparison between the current remaining battery capacity and the base point information to the user who is driving the electric vehicle.
