Patent number: 11951988Abstract: When a vehicle control interface receives information indicating “Forward” from a VP, the vehicle control interface sets a value 0 in a signal indicating a rotation direction of a wheel. When the vehicle control interface receives information indicating “Reverse” from the VP, the vehicle control interface sets a value 1 in the signal indicating the rotation direction of the wheel. When the vehicle control interface receives information indicating “Invalid value” from the VP, the vehicle control interface sets a value 3 in the signal indicating the rotation direction of the wheel. The vehicle control interface provides the signal indicating the rotation direction of the wheel to an ADK.Type: GrantFiled: April 18, 2022Date of Patent: April 9, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ikuma Suzuki, Yuta Ohashi

Publication number: 20240075840Abstract: A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.Type: ApplicationFiled: August 29, 2023Publication date: March 7, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Patent number: 11891055Abstract: A vehicle comprises an autonomous driving system and a vehicle platform that controls the vehicle in response to a command received from the autonomous driving system. In the present vehicle, when the autonomous driving system issues a first command to request the vehicle platform to provide deceleration to stop the vehicle and a first signal indicates 0 km/h or a prescribed velocity or less, the autonomous driving system issues a second command to request the vehicle platform to maintain stationary. And after brake hold control is finished, a second signal indicates standstill. Until the second signal indicates standstill, the first command continues to request the vehicle platform to provide deceleration.Type: GrantFiled: April 18, 2022Date of Patent: February 6, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ikuma Suzuki, Yuta Ohashi

Publication number: 20240037597Abstract: A server manages power adjustment resources electrically connected to a power network. The power adjustment resources include power equipment installed in a facility and configured to supply power from a vehicle to the power network and charge power from the power network to the vehicle. When reservation information for using the facility is received from a user, the server predicts a power supply-demand balance in the power network on a reserved date and time of use of the facility. When a DR for adjusting the power supply-demand balance is predicted to be performed on the reserved date and time of use, the server prepares a use plan for the facility so as to include the vehicle participating in the DR using the power equipment. The server gives an incentive to the user when the user accepts the use plan.Type: ApplicationFiled: June 1, 2023Publication date: February 1, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Osamu YUMITA, Yoichi ONISHI, Toru ANDO, Ikuma SUZUKI, Yu NAGATA

Patent number: 11747812Abstract: When a vehicle control interface receives information indicating “Standstill” from a VP, the vehicle control interface sets a value 2 in a signal indicating an actual moving direction (a signal indicating a moving direction of a vehicle). When the number of wheels rotating in a forward rotation direction is larger than two, the vehicle control interface sets a value 0 in the signal indicating the actual moving direction. When the number of wheels rotating in a reverse rotation direction is larger than two, the vehicle control interface sets a value 1 in the signal indicating the actual moving direction. When the number of wheels rotating in the forward rotation direction is equal to the number of wheels rotating in the reverse rotation direction, the vehicle control interface sets a value 3 in the signal indicating the actual moving direction. The vehicle control interface provides the signal indicating the actual moving direction to an ADK.Type: GrantFiled: January 21, 2021Date of Patent: September 5, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ikuma Suzuki, Yuta Ohashi
