VEHICLE POWER SUPPLY SYSTEM

A vehicle power supply system is configured to supply power to a vehicle from a power supply apparatus laid on a power supply lane of a vehicle travel path, the power supply apparatus includes a plurality of power supply segments laid in a preset interval along the power supply lane, and a controller configured to control the plurality of power supply segments. The controller is configured to estimate timing of the vehicle reaching a next power supply segment that supplies power next after a present power supply segment that is supplying power, from at least a vehicle velocity derived from a change in position of the vehicle, and cause the next power supply segment to start power supply at the timing estimated.
