  • Publication number: 20240034161
    Abstract: A vehicle charging and discharging system to be applied to an electric vehicle includes a rectifier, an inverter, a relay, and a control processor. The rectifier is disposed on a charging path through which a battery of the electric vehicle is to be contactlessly charged from external equipment via a coil in the electric vehicle. The inverter is disposed on a first path from the battery to an electric power output terminal of the electric vehicle, the electric power output terminal allowing for output of electric power stored in the battery. The relay is disposed on a second path from the inverter to the coil. The control processor controls an operation state of the relay to allow the electric power stored in the battery to be contactlessly discharged to the external equipment via the inverter, the relay, and the coil on the second path.

  • Patent number: 11485345
    Abstract: A vehicle control apparatus, configured to control a vehicle, includes an engine that is configured to drive wheels via a power transmission device. The vehicle control apparatus includes a towing state detector and an engine controller. The towing state detector is configured to detect whether the vehicle is in a towing state. The engine controller is configured to stop the engine in a case where a predetermined engine stopping condition is satisfied during traveling of the vehicle. The engine controller is configured to vary, in a case where the towing state detector detects that the vehicle is in the towing state, the predetermined engine stopping condition to reduce an operational range in which the engine is to be stopped compared with an operational range in a case where the towing state detector does not detect that the vehicle is in the towing state.

  • Patent number: 10995850
    Abstract: A vehicle includes a transmission shiftable by hydraulic pressure, a main oil passage that delivers operating oil, a first oil passage that delivers the operating oil from the main oil passage to the transmission, a first valve that opens/closes the first oil passage, a controller that controls the first valve, a second oil passage that delivers the operating oil from the main oil passage to the transmission, and a manually drivable second valve that opens/closes a section of the first oil passage that is closer to the main oil passage than the first valve and the second oil passage. The second valve is switchable between the automatic control state in which the first oil passage is opened and the second oil passage is closed and the manual control state in which the first oil passage is closed and the second oil passage is opened.
