An input of a destination and an input of a desired number of power supply facilities via which a vehicle travels on a route from a present location to the destination until an amount of power available becomes 0 are received. The number of facilities are selected and the route to the destination via the number of facilities is specified, the number of facilities being selected such that an amount of power with which the vehicle is able to travel a distance obtained by adding a margin distance to a distance to a farthest facility is less than the amount of power available when the route is specified. An alert is reported when the amount of power available is less than an amount of power required to travel the distance obtained by adding the margin distance to the distance to the farthest facility of the selected facilities.

An automatic guiding method for a self-propelled apparatus (10) is provided. The self-propelled apparatus (10) turns and irradiates when a signal light emitted by a charging dock (20) is sensed by a flank sensor (103), and changes its turn direction when another different signal light from the charging dock (20) is sensed by a forward sensor (102). The charging dock (20) switches to emit another signal light different from the signal light currently emitted when each time is triggered by the signal light emitted by the self-propelled apparatus (10). Repeatedly execute the above actions and make the self-propelled apparatus approach the light-emitting unit (202) until the self-propelled apparatus (10) reaches a charging position. It can accurately guide the self-propelled apparatus (10) to the charging position by arranging only two sensors on the self-propelled apparatus.

A system and method are provided for a feed-forward control of an inverter to reduce, and potentially minimize, a DC link capacitor of a wireless power transfer system. The feed-forward control may be utilized to reduce the capacitance of the DC link capacitor in a single-phase series-series compensated WPT system.

A motor device for a vehicle includes a stator, a rotor, a bearing, an inverter, and a controller. The stator is attached into a housing and includes a concentrated winding coil. The rotor includes a permanent magnet. The bearing supports a rotating shaft of the rotor. The inverter controls an energization state of the concentrated winding coil. If a rotational speed of the rotor is greater than a threshold, the controller outputs a control signal to the inverter to execute field weakening control, and thereby makes a potential difference between the housing and the rotating shaft lower than a withstand voltage of the bearing. The control signal controls the energization state of the concentrated winding coil. The field weakening control generates magnetic flux of the concentrated winding coil in a direction of weakening magnetic flux of the permanent magnet.
