Abstract
There is provided a vehicle operating system constituted of a vehicle and at least a charging apparatus, the system comprising means for enabling high-precision unmanned positioning, despite primarily vertical displacements of the vehicle due to changes in tire pressure or weight of a passenger or passengers, and hence enabling efficient, stable power feeding. The charging apparatus includes a power feeding unit, and a vehicle includes a power receiving unit for feeding power in a noncontact manner, which makes possible recharging without manual assistance. A C-shaped transformer and an I-shaped transformer are used for the power feeding unit and the power receiving unit, respectively, so that a magnetic flux induced therebetween can develop substantially in the horizontal direction, thereby feeding power stably despite changes in tire pressure and the like. Tire guides for guiding the vehicle to a power feeding position and a car stop are so used that when the vehicle 1 comes in contact with the car stop, the power feeding unit and the power receiving unit will face each other in a correct position, thus enabling high-precision positioning at power feeding time.
