CN-117465173-B - Vehicle state grasping system and vehicle state grasping method

Abstract

The invention provides a vehicle state grasping system and a vehicle state grasping method. The system management server determines that the tire pressure of the vehicle has been reduced to a predetermined abnormal value and then returns to a normal value without performing a tire replacement operation or a tire repair operation (for example, when there is a driver who continues to run the vehicle by supplying air without performing a tire replacement even if the tire is perforated), and transmits abnormality notification information to the manager terminal device. Thus, the manager provides warning information to the current driver of the vehicle by the manager's operation of the manager terminal device.

Description

Vehicle state grasping system and vehicle state grasping method Technical Field The present invention relates to a vehicle state grasping system and a vehicle state grasping method. In particular, the present invention relates to an improvement in response to a situation in which the air pressure of the tires of a vehicle is reduced to a predetermined abnormal value in a vehicle state grasping system in which a plurality of drivers share the vehicle under the management of a manager. Background Conventionally, as a system for grasping a state of a vehicle, a system disclosed in japanese patent application laid-open No. 2002-132994 is known. Japanese patent application laid-open No. 2002-132994 discloses a tire management server that receives data indicating the state of a tire from a vehicle terminal, and when it is determined that processing of the tire (repair of the tire or the like) needs to be performed in an emergency, contacts the state of the tire with the corresponding vehicle terminal. More specifically, all tires are equipped with a transponder, and tire air pressure data is externally transmitted to the tire management server together with the tire ID at prescribed time intervals. Disclosure of Invention However, when a plurality of drivers share a vehicle under the management of a manager (for example, when a plurality of drivers alternately ride the same taxi under the management of a taxi company, etc.), there is a possibility that even if a tire is perforated (perforated to such an extent that air is gradually discharged), a driver who does not perform tire replacement (tire replacement work) and continues to drive the vehicle (avoid troublesome tire replacement work) by supplementing air (supplementing air at a service station, etc.). In this case, the driver who takes the vehicle later is forced to perform the tire replacement work and the puncture repair work, and the burden on the driver increases. In addition, there is a problem that the driver is not satisfied with the tire because the driver does not puncture the tire (for example, the driver must perform tire replacement work and puncture repair work even though the driver has already punctured the tire at the time of riding a taxi (starting inspection time point in the case of a taxi). In japanese patent application laid-open No. 2002-132994, there is no technical idea for solving such problems, and there is room for improvement in this point. That is, in japanese patent application laid-open No. 2002-132994, since the occurrence of the puncture is notified to the driver at the time point when it is determined that the puncture has occurred in the tire based on the information supplied from the transponder, when the above-described behavior is performed in which the air is supplemented without tire replacement, the notification is released, and the restraining force against the behavior cannot be obtained. The cause of the air pressure of the tire being reduced to an abnormal value is not limited to the case of puncturing the tire, and may be a case where an air valve of the tire is broken. The present disclosure aims to provide a vehicle state grasping system and a vehicle state grasping method capable of prompting a driver who is currently driving a vehicle to take measures such as tire replacement when a situation occurs in which the air pressure of the tires of the vehicle is reduced to a predetermined abnormal value in the vehicle state grasping system in which a plurality of drivers share the vehicle under the management of a manager. The solution of the present invention for achieving the above object is premised on a vehicle state grasping system capable of grasping a state of a vehicle in a vehicle use mode in which a plurality of drivers share the vehicle under management of a manager. The vehicle state grasping system includes: An air pressure recognition unit that recognizes an air pressure of a tire of the vehicle; an air pressure information transmitting unit for transmitting the information of the air pressure of the tire identified by the air pressure identifying unit, and And a system management server for receiving the information of the air pressure of the tire transmitted by the air pressure information transmitting unit. The system management server further includes an abnormality notification information creation unit that creates abnormality notification information when the air pressure of the tire has been reduced to a predetermined abnormal value and is returned to a normal value without performing any one of a tire replacement work and a tire repair work based on the received air pressure information of the tire, The system management server includes an abnormality notification information transmitting unit that transmits the abnormality notification information to a communication device operated by the manager when the abnormality notification information is received from the abnormality notification info
