Kind Code:
A1
Abstract:
This vehicle drive system is provided with: a first battery (111) for storing direct current (DC) power; a DC-AC converter (121a) for converting DC power from the first battery to alternating current (AC) power; a power transmitting means having a power transmitting antenna (122a) that wirelessly transmits AC power; a power receiving antenna that wirelessly receives the AC power transmitted by the power transmitting antenna; a power receiving means having an AC-DC converter (201a) that converts AC power to DC power; a motor (M) that is mounted to the hub of a wheel; a second battery (212a) that is provided to the wheel, and stores the DC power received by the power receiving means; an inverter (203a) that converts DC power from the second battery to AC power; a torque controller (222) that controls the rotary drive of the motor; a residual quantity controller (221) that controls the wireless supply of power from the power transmitting means to the power receiving means; and a vertical stroke detector that detects the vertical stroke volume of the wheel. The residual quantity controller conducts the wireless supply of power from the power transmitting means to the power receiving means if the detected vertical stroke volume is less than a prescribed value.
