Abstract: A display device includes a display unit, an imaging optical element, a detector, and an adjustor. The display unit includes a display surface for displaying an image. The imaging optical element includes an element plane. The imaging optical element causes the image displayed on the display surface to be imaged as an aerial image in an aerial display region positioned plane-symmetrically to the display surface with respect to the element plane. The detector detects a position of a head of a user existing in front of the display region. The adjustor adjusts a position of the image with respect to the imaging optical element based on a detection result obtained by the detector.

Abstract: A display system for use in a mobile body includes an acquisition unit that acquires detection information of at least one detection object that exists in a target space, a display unit that displays a virtual image in the target space, and a controller that controls display of the display unit. In the target space, at least one detection area is provided. The at least one detection object includes a first detection object that exists closest to the mobile body and a second detection object that has the shortest time to collision with the mobile body. The controller determines, as a display object, at least one of the first detection object and the second detection object in the at least one detection object that exists in the detection area based on the detection information, and causes the display unit to display the virtual image corresponding to the display object.

Abstract: A driving support device as an example of a data processor executes processing for estimating a driving behavior of a vehicle by using a driving behavior model trained based on detection results by a sensor. A detected-information input unit acquires detected information including the detection results. From the detection results included in the detected information input to the detected-information input unit, a selection unit selects a detection result that falls within predetermined selection range narrower than a range detectable by the sensor. A processing unit executes the processing, based on the detection result selected by the selection unit.

Abstract: An automation level determination section selects one of automation levels defined at a plurality of stages based on a deviation degree of reliability, the deviation degree corresponding to each of a plurality of kinds of driving behaviors that are estimation results obtained using a driving behavior model. A generator generates presentation information by applying the plurality of kinds of driving behaviors to an output template corresponding to one selected automation level in output templates corresponding to the automation levels defined at the plurality of stages respectively. An output unit outputs the presentation information that is generated.

Abstract: This automatic driving assistance device automatically performs least a part of vehicle control including steering, braking, and acceleration and deceleration within a predetermined travel section. The automatic driving assistance device includes: a switching section determination unit that determines, in the travel section, a section in which a first load that is based on a road shape or a road structure becomes equal to or less than a predetermined threshold as a switching section in which the at least a part of the vehicle control is switched from automatic driving to manual driving; a driving action planning unit that, when the vehicle enters the determined switching section, generates an automatic driving action plan so that a second load that is based on a travel situation of nearby vehicles around the vehicle is reduced; and a driving switching unit that ends automatic driving that is based on the automatic driving action plan and switches the automatic driving to the manual driving.

Abstract: The driving assistance device acquires, from an autonomous driving controller that determines an action of a vehicle during autonomous driving of the vehicle, action information indicating a first action that the vehicle is caused to execute. The driving assistance device acquires, from a detector that detects a surrounding situation and a travel state of the vehicle, detection information indicating a detection result. The driving assistance device determines a second action which is executable in place of the first action, based on the detection information. The driving assistance device generates a first image representing the first action and a second image representing the second action. The driving assistance device outputs the first image and the second image to a notification device such that the first image and the second image are displayed within a fixed field of view of a driver of the vehicle.

Abstract: An information processing system receives first travel histories from vehicles that belong to vehicle type A, learns based on the first travel histories to build a first driver model that represents relation between travel situations and behaviors of the vehicles that belong to a first vehicle type, receives second travel histories from vehicles that belong to vehicle type X that is different from vehicle type A, and performs transfer learning in which the second travel histories are used for the first driver model to build a second driver model that represents relation between travel situations and behaviors of the vehicles that belong to vehicle type X.

Abstract: An event prediction system includes an accumulation unit and a generator. The accumulation unit accumulates a plurality of pieces of learning data each including history information representing a situation of a mobile object upon occurrence of an event associated with driving of the mobile object. The generator generates a prediction model for prediction of relative coordinates of an occurrence place of the event relative to the mobile object by using the plurality of pieces of learning data. Each of the plurality of pieces of learning data further includes label information representing the relative coordinates of the occurrence place of the event relative to the mobile object.
