In a safe driving support system, a data center is connected to a plurality of vehicles via a communication network. The data center stores a position of a first vehicle of which a G sensor detects that behavior of the vehicle has been disturbed when caution information is received from the first vehicle as a caution-needed spot in a storage device. The data center transmits data of a caution image extracted from data of images in a predetermined period before the caution information has been received out of the data of the images captured by a drive recorder of the first vehicle to a second vehicle approaching the caution-needed spot when the caution information is received. The display of the second vehicle having received the data of the caution image attracts attention by displaying the caution image before the second vehicle arrives at the caution-needed spot.

Safe driving support system and safe driving support method

An information providing device and an information providing method are provided. Processing circuitry receives, from a first vehicle, a piece of video data related to the moment the first vehicle passed an occurrence site. The first vehicle captures a piece of video data by a dashboard camera when passing the occurrence site of a traffic event requiring cautious driving. The processing circuitry extracts a piece of image data representing a situation of the occurrence site from the video related to the piece of video data, and transmits the piece of image data to the second vehicle. When the second vehicle reaches a notification location, a display device of the second vehicle displays an image related to the piece of image data in order to issue an alert.

Information providing device and information providing method

A vehicle includes a processor configured to receive information for traveling guidance, which is generated based on an image of a specific point. The image of the specific point is captured by another vehicle, and the specific point is a point at which a traveling route of a different vehicle deviates from a guidance route.

Vehicle for receiving traveling guidance that is generated based on an image of a specific point

In an in-vehicle terminal device that is able to perform communication with a server device, an identification information acquisition unit acquires identification information of a user who boards a vehicle. A communication unit transmits the identification information of the user to the server device and receives arrangement information of a plurality of display elements corresponding to the identification information of the user transmitted from the server device. A setting unit decides an arrangement of the display elements of the in-vehicle display according to an arrangement criterion based on vehicle type information of the vehicle using the arrangement information of the display elements corresponding to the identification information of the user.

A device mounted on a vehicle includes a processor configured to receive information for traveling guidance, which is generated based on an image of a specific point. The image of the specific point is captured by another vehicle, and the specific point is a point at which a traveling route of a different vehicle deviates from a guidance route.

Server apparatus and information processing method for providing vehicle travel guidance that is generated based on an image of a specific point

A method of generating log data that includes a plurality of records, in which information detected through image recognition processing on a plurality of image frames is recorded. The method includes, detecting objects in each image frame through the image recognition processing, generating a record including identification information of each image frame and the aggregated number of objects detected in the image frame for each image frame, and adding metadata relating to the detected objects to the corresponding record when the aggregated number of objects is equal to or greater than one. When the aggregated number of objects is zero, the metadata related to the detected objects is not added to the record.

Method of generating log data, non-transitory computer-readable medium, and data structure

A driving assistance device for a driver of a vehicle includes an electronic control unit configured to, before the vehicle passes through a predetermined position in a predetermined direction, acquire information relating to a predetermined traffic regulation to be applied when the vehicle passes through the predetermined position in the predetermined direction, acquire an observance tendency of an other driver relating to the predetermined traffic regulation, a degree of similarity between a predetermined characteristic of the other driver and the predetermined characteristic of the driver of the vehicle is equal to or greater than a predetermined value, before the vehicle passes through the predetermined position in the predetermined direction, output a warning to prompt observance of the predetermined traffic regulation, and change an output state of the warning to prompt observance of the predetermined traffic regulation based on the observance tendency of the traffic regulation of another driver.

Driving assistance device, information processing device, driving assistance system, driving assistance method

A vehicle includes a display device that is visible from a front side, a measurement unit configured to measure a distance between the vehicle and a front vehicle which travels in the same direction as the vehicle, and a display control unit configured to horizontally invert display content on the display device based on the measured distance.

Vehicle, display method, and program

An information processing system includes an acquisition unit configured to acquire traveling information indicating traveling conditions of a first vehicle traveling on a road, a determination unit configured to determine one or more driving operations of a driver driving the first vehicle by using the traveling information acquired when a second vehicle approaches the first vehicle, an evaluation unit configured to perform evaluation of safety related to the driver's driving by using determination results of the determination unit, and an updating unit configured to acquire first evaluation results of the evaluation unit during a first predetermined period to compare the first evaluation results with second evaluation results of the evaluation unit during a second predetermined period before the first predetermined period, and to update the second evaluation results based on comparison results.
