The vehicle information is transferred within an in-vehicle network installed in the vehicle. The first sampling pattern is a sampling pattern in which the vehicle information is sampled at a change point at which a predetermined change has occurred. The second sampling pattern is a sampling pattern in which the vehicle information is sampled at intervals of a predetermined period. The electronic control unit is configured to transmit the acquired vehicle information to the management server.

A vehicle system includes an information processing device and a vehicle. The vehicle includes: a detection unit configured to detect an illuminance change; an acquisition unit configured to acquire position information; a first sending unit configured to send, to the information processing device, (i) illuminance change position information and (ii) traveling information; a first receiving unit configured to receive a turn-on condition from the information processing device; and a turn-on unit configured to turn on a headlight according to the traveling information and the turn-on condition. The information processing device includes a learning unit configured to learn, as the turn-on condition, traveling content of the vehicle before the vehicle reaches the position where the illuminance change is detected, by using the travelling information, and a second sending unit configured to send the turn-on condition to the vehicle.

Vehicle system, vehicle, and information processing device

A vehicle-mounted device control system includes a first vehicle-mounted device, a second vehicle-mounted device, and a control unit connected to the first vehicle-mounted device and the second vehicle-mounted device. The control unit includes signal transmission means that transmits a predetermined signal to the first vehicle-mounted device, cooperative control means that performs cooperative control in which the second vehicle-mounted device is controlled using information used by the first vehicle-mounted device when the first vehicle-mounted device responds to the predetermined signal, and alternative control means that performs alternative control in which the second vehicle-mounted device is controlled without using information, used by the first vehicle-mounted device, when the first vehicle-mounted device does not respond to the predetermined signal.

Vehicle-mounted device control system

Driving assistance systems, methods, and programs for a vehicle, acquire a travel history of a vehicle, acquire a guidance target point at which a guidance target event has occurred based on the travel history, and acquire a tendency of a driving operation of a driver of the vehicle based on the travel history. The systems, methods, and programs determine whether to provide guidance on the guidance target point based on the tendency of the driving operation, and provide guidance relating to the guidance target point for which it is determined to provide the guidance.

Driving assistance system, method, and program for a vehicle

Drive assist systems, methods, and programs acquire a stored guide location where guidance associated with a guide event as a guide target will be provided, acquire event information indicating whether the guide event was detected from a vehicle that can selectively provide or not provide guidance associated with the guide event and which is set to provide guidance, and which detected the guide event at the guide location. The systems, methods, and programs determine whether to stop providing guidance for the guide event at the guide location based on the event information, correct stored information to stop providing guidance for the guide event at the guide location when it is determined to stop providing guidance, and acquire and transmit to the vehicle information indicating the guide location for which provision of guidance associated with the guide event has not been stopped and the guide event from the storage medium.

Warning guidance systems, methods, and programs communicate with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle. The systems, methods, and programs acquire warning event information indicating the warning event and an event vehicle on which the warning event has occurred. The systems methods and programs transmit the guidance to the vehicle traveling in a predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a plurality of event vehicles, but do not transmit the guidance at another vehicle traveling in the predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a single event vehicle for all of the plurality of times.

Systems, methods, and programs distribute traffic information including information on a wrong-way vehicle traveling in a wrong-way direction opposite to a designated travel direction of a road. The systems, methods, and programs distributes the traffic information to the target vehicle, determine a reporting range of the wrong-way vehicle information based on a wrong-way vehicle position. When an end-point distance is equal to or larger than a predetermined reference distance, the systems, methods, and programs set a wrong-way section as the reporting range. When the end-point distance is less than the reference distance, the systems, methods, and programs set the wrong-way section and at least one road section which is adjacent to the wrong-way section as the reporting range. When the target vehicle is in the reporting range, the systems, methods, and programs send the traffic information including the wrong-way vehicle information to the target vehicle.

Various sensors, such as a GPS and a vehicle speed sensor, are used to detect a current position and direction of a vehicle. A normal running direction, which is a running direction specified for a road on which the vehicle runs, is acquired. In a state where a vehicle speed pulse is acquired at the predetermined intervals, it is detected whether the vehicle is placed in a wrong-way driving situation on the basis of the detected current direction of the vehicle and the normal running direction; whereas, in a state where a vehicle speed pulse is not acquired, it is not detected whether the vehicle is placed in the wrong-way driving situation on the basis of the detected current direction of the vehicle.

Driving support system, driving support method and computer program

A support control unit for determining a traveling condition of a host vehicle during an exit from a main road to an access road determines whether or not the condition of the host vehicle at a given point in time corresponds to an exit start scene or an exit completion scene for detecting the start of an exit or completion of the exit on the basis of a host vehicle position, route data, map rendering data, or lane information including at least road surface marking positions, and determines that an exit start timing or an exit completion timing of the host vehicle has arrived when the condition is determined to correspond to the exit start scene or the exit completion scene. Hence, during the exit from the main road to the access road, the traveling condition of the host vehicle can be determined accurately. The support control unit also determines the traveling condition of the host vehicle during convergence with the main road from the access road.

A hybrid vehicle includes a regenerative charging area detection section, a recovery loss estimation section, and a motor use ratio increase section. The regenerative charging area detection section detects arrival of a regenerative charging possible area in which a regenerative charging from a motor to a battery is possible. The recovery loss estimation section estimates a recovery loss of the regenerative charging based on a regenerative charge amount in the regenerative charging possible area and a current remaining battery amount in response to detection by the regenerative charging area detection section. In response to estimation by the recovery loss estimation section, before the arrival at the regenerative charging possible area, the motor use ratio increase section increases a use ratio of the motor so as to decrease a remaining battery amount while limiting the temperature of the battery to a predetermined temperature range.
