Publication number: 20230271631Abstract: A vehicle is a vehicle on which an ADK is mountable. The vehicle includes: a VP that controls the vehicle in accordance with an instruction from the ADK; and a VCIB that serves as an interface between the ADK and the VP. The VP outputs an accelerator pedal position signal in accordance with an amount of depression of an accelerator pedal by a driver, and outputs an accelerator pedal intervention signal, to the ADK through the VCIB. The accelerator pedal intervention signal indicates that the accelerator pedal is depressed, when the accelerator pedal position signal indicates that the amount of depression is larger than a threshold value, and indicates beyond autonomy acceleration of the vehicle, when an acceleration request in accordance with the amount of depression is higher than a system acceleration request.Type: ApplicationFiled: April 28, 2023Publication date: August 31, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Ikuma SUZUKI

Patent number: 11738745Abstract: 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: August 29, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ikuma Suzuki, Yuta Ohashi

Patent number: 11733701Abstract: 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. 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: April 18, 2022Date of Patent: August 22, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ikuma Suzuki, Yuta Ohashi
