  • Publication number: 20220402389
    Abstract: A vehicle receiving power from a ground power supplying apparatus by noncontact includes: a vehicle side first communication device for directly or indirectly communicating with the ground power supplying apparatus by utilizing wide area wireless communication; a vehicle side second communication device for directly communicating with the ground power supplying apparatus by utilizing short range wireless communication; and a control device for making the vehicle side first communication device transmit vehicle information tied with vehicle identification information to the ground power supplying apparatus and making the vehicle side second communication device transmit the vehicle identification information to the ground power supplying apparatus after the vehicle side first communication device transmits the vehicle information, when the vehicle receives power from the ground power supplying apparatus.

  • Patent number: 11458950
    Abstract: A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

  • Patent number: 11091031
    Abstract: A drive force control system for a vehicle configured to allow a driver to find out a steering angle at which a wheel grips a road surface. In the vehicle, a torque distribution ratio to a pair of wheels turned by a steering wheel and another pair of wheels is changeable. A controller restricts a control to change the torque distribution ratio in the event of a slip of the pair of wheels, if a steering angle of the pair of wheels is changed to allow the pair of wheels to grip a road surface.

  • Publication number: 20210107450
    Abstract: A drive control system for a hybrid vehicle configured to prevent backward coasting on an uphill grade even when an engine torque cannot be delivered to drive wheels. When the hybrid vehicle is propelled by delivering engine torque to rear wheels on an uphill grade, the drive control system determines an occurrence of a failure in which the torque cannot be delivered from the engine to the rear wheels. If the occurrence of the failure is determined, the drive control system executes a hill hold control to deliver torque to establish a required drive force from a motor to front wheels while disengaging an engagement device.
