CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from Japanese Patent Application No. 2020-145301 filed on Aug. 31, 2020, the entire contents of which are hereby incorporated by reference.

BACKGROUND

The disclosure relates to a vehicle with an automatic accident report function and a server apparatus.

If an accident occurs for a vehicle such as an automobile, accident information may be reported. For example, an emergency report system is put into practical use for automobiles. With the emergency report system, an automobile involved in an accident transmits the accident information to a server apparatus at a call center by using an automatic report apparatus provided in the automobile (Japanese Unexamined Patent Application Publication No. 2001-216588). The accident information includes an operation state and the location of an occupant protection apparatus at the time of the accident and the input direction and strength of impact in the accident. At the call center, the server apparatus receives the accident information from one or more automobiles, and the accident information is checked to request the dispatch of a rescue team with an air ambulance or ambulance. This can shorten a lead time before the air ambulance or ambulance is dispatched. Thus, an occupant or occupants of the vehicle or vehicles involved in the accident are more likely to be saved.

SUMMARY

An aspect of the disclosure provides a vehicle with an automatic accident report function. The vehicle includes a transmitter, a collector, a determiner, and a vehicle estimator. The transmitter is configured to automatically transmit, from the vehicle to a server apparatus, accident emergency information that is usable by the server apparatus to estimate injury of an occupant of the vehicle when an accident of the vehicle is detected or forecasted. The collector is configured to collect, in the vehicle, information of the vehicle involved in the accident. The determiner is configured to determine whether a communication environment is appropriate for transmission of the information from the transmitter to the server apparatus. The vehicle estimator is configured to estimate the injury of the occupant of the vehicle, using the information collected by the collector. If the communication environment is inappropriate, the transmitter transmits, as the emergency information to the server apparatus, estimation results of the injury of the occupant estimated by the vehicle estimator, instead of the information of the vehicle collected by the collector.

An aspect of the disclosure provides a server apparatus including a receiver, a server estimator, and an outputter. The receiver is configured to receive accident emergency information that is automatically transmitted in response to a vehicle detecting or forecasting an accident. The server estimator is configured to estimate injury of an occupant of the vehicle on a basis of the emergency information when the receiver receives the emergency information. The outputter is configured to output estimation results of the injury of the occupant estimated by the server estimator. When the receiver receives, as the emergency information, estimation results of the injury of the occupant estimated by the vehicle instead of accident information that is usable by the server apparatus to estimate the injury of the occupant of the vehicle, the outputter outputs the estimation results of the injury of the occupant estimated by the vehicle.

An aspect of the disclosure provides a vehicle with an automatic accident report function. The vehicle includes a transmitter and circuitry. The transmitter is configured to automatically transmit, from the vehicle to a server apparatus, accident emergency information that is usable by the server apparatus to estimate injury of an occupant of the vehicle when an accident of the vehicle is detected or forecasted. The circuitry is configured to collect, in the vehicle, information of the vehicle involved in the accident. The circuitry is configured to determine whether a communication environment is appropriate for transmission of the information from the transmitter to the server apparatus. The circuitry is configured to estimate the injury of the occupant of the vehicle, using the information collected by the collector. If the communication environment is inappropriate, the transmitter transmits, as the emergency information to the server apparatus, estimation results of the injury of the occupant, instead of the information of the vehicle collected by the collector.

The receiver is configured to receive accident emergency information that is automatically transmitted in response to a vehicle detecting or forecasting an accident. The circuitry is configured to estimate injury of an occupant of the vehicle on a basis of the emergency information when the receiver receives the emergency information. The circuitry is configured to output estimation results of the injury of the occupant. When the receiver receives, as the emergency information, estimation results of the injury of the occupant estimated by the vehicle instead of accident information that is usable by the server apparatus to estimate the injury of the occupant of the vehicle, the circuitry outputs the estimation results of the injury of the occupant estimated by the vehicle.
