An ECU controls a vehicle including a power reception unit that can wirelessly receive electric power from a power feeding facility placed on a travel road. The ECU includes a memory in which a user-desired condition is stored, the user-desired condition being a condition under which a user of the vehicle desires on-road power reception, the on-road power reception being power reception from the power feeding facility placed on the travel road, and a processor connected to the memory. When a physical condition for power feeding from the power feeding facility to the vehicle is satisfied and when the user-desired condition stored in the memory is not satisfied, the processor controls the power reception unit to suppress on-road power reception.

A controller of a hybrid vehicle includes: a control unit configured to activate a starter device for starting any one of a drive motor and an engine by stepping up electric power from a battery by a voltage transformer. The control unit includes a limitation part that limits passing power of the voltage transformer when the temperature of the voltage transformer rises, and a calculation part that obtains a maximum electric power that can be supplied to the drive motor when the starter device is activated, by subtracting a consumed power of the starter device from limited power during limitation of passing power by the limitation part. The control unit activates the starter device and starts the engine, when required power of the drive motor reaches the maximum electric power calculated by the calculation part during limitation of passing power by the limitation part.

An electric multi-mode drive system (400), a method for operating the same, a vehicle (110) and a track (401). The system is arranged for operating at one part (402) of the track (401), at a station (410; 411), an electric Linear Doubly Fed Motor, LDFM, (310) for launching the vehicle (110), and for operating at another part (403) of the track (401), between stations (410; 411), a further electric motor (320; 330; 340; 350), not an LDFM, arranged for at least one of accelerating, coasting and restarting movement of the vehicle (110) after launching. Electric power for operating the further electric motor (320; 330; 340; 350), is provided by an on-board rechargeable electrical energy storage device. With the LDFM (310), sufficient power is generated for accelerating the vehicle (110), and recharging the on-board electrical energy storage device during standstill, braking and/or launching.
