A vehicle includes: a traction motor; and a drive controller. The traction motor includes a rotational position sensor configured to detect a rotational position of a rotor magnetically. The drive controller controls a driving current output to the traction motor. The drive controller is able to switch a control mode of the driving current between a sensing control mode configured to control the driving current by using a detection result from the rotational position sensor and a sensing-less control mode configured to control the driving current without using a detection result from the rotational position sensor.

Wireless power supply for vehicle

A vehicle includes: a traction motor; a diagnostic module; a receiving coil; and a controller. The diagnostic module executes a diagnostic test of a rotational position sensor of the traction motor. The receiving coil receives a power wirelessly. The controller switches the diagnostic module to a state that is less likely to determine an error than normal when the receiving coil is positioned with respect to a supplying coil in a ground equipment.
