  • Publication number: 20220250648
    Abstract: An ADS performs processing including setting an immobilization command to “Applied” when an autonomous state has been set to an autonomous mode, when an acceleration command has a value indicating deceleration, when an actual moving direction indicates a standstill state, and when a wheel lock request is issued, setting the acceleration command to V1, and setting the acceleration command to zero when an immobilization status has been set to “11”.

  • Publication number: 20220250616
    Abstract: 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.

  • Publication number: 20220242412
    Abstract: 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.

  • Publication number: 20220242445
    Abstract: A vehicle (10) includes a VP (120) that carries out vehicle control in accordance with a command from an autonomous driving system (202) and a vehicle control interface (110) that interfaces between the autonomous driving system (202) and the VP (120). A tire turning angle command that requests for a wheel steer angle is transmitted from the autonomous driving system (202) to the VP (120). A signal indicating an estimated wheel angle which is an estimated value of the wheel steer angle is transmitted from the VP (120) to the autonomous driving system (202). The VP (120) steers the vehicle in accordance with the tire turning angle command set based on a wheel estimation angle while the vehicle (10) is in a straight-ahead travel state.

  • Publication number: 20220244733
    Abstract: 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.

  • Publication number: 20220242484
    Abstract: A vehicle includes an ADK attachable to and removable from a vehicle main body, the ADK issuing an instruction for autonomous driving, a VP including a plurality of functional units that perform a plurality of prescribed functions of the vehicle main body, and a VCIB that issues a control instruction to the functional units in accordance with an instruction from the ADK. One of the plurality of functional units is a steering system that steers the vehicle main body. The steering system specifies a limit value of a steering rate in accordance with a prescribed reference and transmits the specified limit value to the ADK through the VCIB. The ADK calculates a target steering angle to satisfy the limit value received from the steering system and transmits an instruction for the calculated steering angle to the steering system through the VCIB.

  • Publication number: 20220242456
    Abstract: A vehicle is a vehicle on which an autonomous driving kit (ADK) is mountable. The vehicle includes: a vehicle platform (VP) that controls the vehicle in accordance with an instruction from the ADK; and a vehicle control interface that serves as an interface between the ADK and the VP. The VP receives a driver deceleration request in accordance with an amount of depression of a brake pedal by a driver, and receives a system deceleration request from the ADK through the vehicle control interface. During an autonomous mode, the VP specifies the sum of the driver deceleration request and the system deceleration request as a target deceleration of the vehicle.

  • Publication number: 20220234611
    Abstract: 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.
