Abstract: A driving assistance device includes an object detection unit configured to detect a hazardous object that is capable of causing an accident in a path of a subject vehicle and surroundings of the path, and an evasive driving detection unit configured to detect features of driver's evasive driving, in which a driver of the subject vehicle performs driving operations to avoid danger of the accident when the subject vehicle approaches and passes by the hazardous object detected by the object detection unit. The driving assistance device further includes a concentration level determination unit configured to determine a concentration level of the driver on driving based on the features of driver's evasive driving detected by the evasive driving detection unit, and a notification unit configured to, when the concentration level determination unit determines that the concentration level of the driver on driving is dropping, provide a notification to encourage safe driving.

Abstract: A drive mode switch control device acquires operation information. The drive mode switch control device switches a drive state among at least an autonomous drive state, a manual drive state, and a coordination drive state. The operation detection unit detects a first operation and a second operation based on the operation information when the drive state is not in the manual drive state. The second operation is the drive operation different from the first operation and input after the input of the first operation. The drive mode switch control device switches the drive state from the autonomous drive state to the coordination drive state based on a detection determination of the first operation. The drive mode switch control device switches the drive state from the coordination drive state to the manual drive state based on a detection determination of the first operation.

Abstract: An object model learning method includes: in an object identification model forming a convolutional neural network and a warp structure warping a feature map extracted in the convolutional neural network to a different coordinate system, preparing, in the warp structure, a warp parameter for relating a position in the different coordinate system to a position in a coordinate system before warp; and learning the warp parameter to input a capture image in which an object is captured to the object identification model and output a viewpoint conversion map in which the object is identified in the different coordinate system.

Abstract: A recognition unit recognizes a specific sign in a captured image acquired by an image acquisition unit. A first notification processing unit displays a specific captured image as a captured image showing the specific sign on a display device in a vehicle. A second notification processing unit provides a notification in a notification mode different from the display of the specific captured image. The recognition unit recognizes a start sign that is a sign indicating the start of an automatic driving permitted zone as a zone where running in an automatic driving mode is permitted, as the specific sign, in the captured image. When the recognition unit recognizes the start sign, the first notification processing unit displays on the display device a start captured image that is the captured image showing the start sign as the specific captured image. When the recognition unit recognizes the start sign, the second notification processing unit notifies the start of the automatic driving permitted zone in a notification mode different from the display of the start captured image.

Abstract: A control unit performs driving assistance. An acquiring unit acquires future circumstance information related to a future circumstance that an own vehicle is predicted to subsequently encounter on a route further ahead of a current location. A determining unit determines whether or not the future circumstance indicated by the acquired future circumstance information is applicable to an event in which continuation of driving assistance is not possible. An urgency level setting unit sets an urgency level that indicates a level of urgency of the future circumstance when the determining unit determines that continuation of driving assistance is not possible. A limit setting unit sets a limit related to time or distance at which to cancel driving assistance and switch to manual driving, based on the set urgency level. A notifying unit notifies a driver of information prompting cancellation of driving assistance based on content of the set limit.

Abstract: A presentation control apparatus is configured to control information presentation to a driver of a vehicle capable of performing automated driving. The presentation control apparatus includes a judging section and a presentation control section. The judging section is configured to distinguish between a particular action permitted state where the driver is permitted to take a particular action other than driving during the automated driving, a particular action prohibited state where the driver is prohibited to take the particular action during the automated driving, and an automated driving prohibited state where the automated driving is prohibited. The presentation control section is configured to present first transition information related to a transition from the automated driving prohibited state to the particular action permitted state in an emphasized form compared to second transition information related to a transition from the particular action prohibited state to the particular action permitted state.

Abstract: A shift selector device includes an input member, a position setting mechanism and an activation controller. A selection operation of selecting a shift position is input to the input member. The position setting mechanism defines a movable range of the input member while supporting the input member in a displaceable manner. A plurality of the shift positions and at least one activation position linked to an automated travel system are disposed in the movable range. When the activation position is selected by displacement of the input member, the activation controller outputs an activation instruction for instructing a control function of the automated travel system linked to the activation position to be activated.
