A drive assistance system includes a display object configurator that sets, as a display object or a non-display object, each of traffic participants recognized as alert objects from among nearby traffic participants, and a display controller that performs highlight image processing for highlighting the presence of the display object. When a first traffic participant set as the display object and a second traffic participant set as the non-display object are present in the vicinity of the subject vehicle and recognized as alert objects with the recognition of the first traffic participant by the driver being detected while the highlight image processing is performed, the display object configurator compares the degrees of influence of the first and second traffic participants, sets, as the display object, one of the first and second traffic participants designated on the basis of a result of the comparison, and sets the other as the non-display object.

Drive assistance system

To reduce a chance that the driver overlooks the object that should be seen, a visual guidance device for guiding a visual line of a driver of the vehicle to an object existing ahead of the vehicle includes an object recognition unit for recognizing the object, and a display control unit for causing the display device to display the visual guidance virtual image for guiding the driver's visual line to a position corresponding to the object recognized by the object recognition unit on a windshield of the vehicle. The display control unit sets a length of the visual guidance virtual image to be displayed by the display device in the vehicle width direction to a length in accordance with a status of the object existing ahead of the vehicle.

Visual guidance device, attention calling system, attention calling method, and program

The virtual image display device comprises a surrounding state recognizer that acquires a travel direction distance and a lateral direction distance to an object, and a display controller that displays object icon images I, Iin a screen. The display controller is capable of switching between displaying an image in a normal mode, in which the display positions of the images I, Imove closer in a lateral direction to a lateral reference line Las the travel direction distance increases, and move farther away in a screen vertical direction from a screen bottom line Las the travel direction distance increases, and displaying the image in a magnification mode, in which a vertical scale, which is the ratio of the distance between the line Land the display positions in the screen vertical direction to the orientation direction distance, is larger than in the normal display mode.

Virtual image display device

The alert system includes a projection device, a display control unit, and a target object recognition unit. When a state changes from a state where a target object is not recognized by the target object recognition unit to a state where a target object is recognized by the target object recognition unit, the display control unit causes the projection device to output an alert display on a front window such that the length of the alert display is gradually shortened toward a position where a direction from an operator to the target object intersects with a front window.

Alert system and recording medium

An information display device includes a display unit configured to display information about an object such that the information about the object at least partially overlaps with forward view of a user, and a controller configured to control display of the display unit. The controller is configured to estimate or acquire a prospective moving direction of the object, acquire a sight-line frequency representing a frequency with which a sight-line of the user is directed to the object within a prescribed period, determine whether the sight-line frequency is equal to or more than a prescribed frequency threshold, and cause the display unit to display the prospective moving direction of the object at least on condition that the controller determines that the sight-line frequency is less than the frequency threshold.

Information display device

An alert system includes a display device, a display control unit, and a target recognition unit. The display control unit: when the number of targets recognized by the target recognition unit is equal to or more than an upper limit number, sets a display range of a surrounding icon as a whole circular area; and in a state where the number of targets is equal to or more than the upper limit number and the display range of the surrounding icon is set as the whole circular area, when the number of targets increases, reduces the size of the surrounding icon.

The attention calling system includes a detection unit for detecting an object around a moving body, and a attention calling unit for outputting a visual display in a horizontally extending belt-like range on an interior structure of the moving body using a light projection device. The attention calling unit outputs the visual display in the belt-like range at a position corresponding to a direction of the object.

Attention calling system and attention calling method

The attention calling system includes the classification unit for classifying an object into a category based on a traffic scene, the risk calculation unit for calculating the risk value with respect to contact with the object based on the category, and the attention calling unit for outputting the visual display in the horizontally extending belt-like range on the windshield of the moving body. The attention calling unit outputs the visual display in the mode adapted to the risk value of the object.

An attention calling device includes: a processor configured to execute an attention load reduction region setting process that sets an attention load reduction region that is a region monitored by a drive assisting device provided in a subject vehicle according to a drive assisting function exerted by operating the drive assisting device, and a display control process that performs an attention calling process by displaying a virtual image for the attention load reduction region in such a manner that conspicuity of the virtual image is lower than a region other than the attention load reduction region based on a position of the attention load reduction region recognized by a target object position recognizing process during operation of the drive assisting device.
