  • Patent number: 11396944
    Abstract: A transmission system configured to perform a gear change based on a shift operation by an operator is provided, which includes a power transmission system including a transmission and configured to transmit an engine driving force to wheels, a shift operation detecting module, and a transmission controlling module adapted to be executable of a manual rotation synchronizing mode having first and second steps. In the first step, when a first shift operation for changing the transmission to a lower-speed side is detected, the transmission controlling module sends a control signal to a connecting-and-disconnecting mechanism provided to the power transmission system to suspend the transmission of the driving force. In the second step, when a second shift operation is detected, the transmission controlling module sends a control signal to the connecting-and-disconnecting mechanism to resume the transmission of the driving force while the transmission is switched to the lower-speed side.

    Abstract: A vehicle driving control system includes a road map information updating unit, a control information calculation unit, and a driving control execution unit. Upon determining that a stopped vehicle is present ahead of a target vehicle and that the target vehicle is able to pass by the stopped vehicle, the control information calculation unit calculates control information to be used to restrict a vehicle speed to a first set vehicle speed or less until the target vehicle passes by the stopped vehicle, and calculates, if a door of the stopped vehicle has been opened, the control information to be used to restrict the vehicle speed to a second set vehicle speed or less until a set time period elapses from the opening of the door or until the target vehicle passes by the stopped vehicle. The second set vehicle speed is lower than the first set vehicle speed.

  • Publication number: 20220119013
    Abstract: A surrounding space data providing system for a control apparatus for a vehicle includes a space generation processor and a signal generation processor. The space generation processor generates a surrounding space around the vehicle with the vehicle assuming a post-control position and a post-control posture, on the basis of a motion of the vehicle based on control data to be outputted by the control apparatus. The signal generation processor generates a generated signal of a space in which an object present in the surrounding space is arranged in the surrounding space in corresponding relation to the post-control position and the post-control posture of the vehicle. The generated signal is as suppliable to the control apparatus as a detection signal to be obtained by detection by an autonomous sensor provided in the vehicle. The signal generation processor outputs the generated signal to the control apparatus in place of the detection signal.

    Abstract: An object estimation device includes an acquisition unit and an estimation unit. The acquisition unit acquires a space image including an object present in a space. The estimation unit estimates image region data on the basis of a portion or all of the space image including the object. The image region data indicates a location of the object in the space image. On the condition that the object included in the space image acquired by the acquisition unit is included in an oblique posture, the estimation unit estimates an image region widened from an image region of the object included in the oblique posture in the space image, as the image region data.
