In-vehicle device, mobile terminal device, recognition support system, recognition support method, and recognition support program

A mobile terminal device that performs communication with an in-vehicle device installed in a vehicle including a detection unit for detecting an object, the mobile terminal device comprising:

• a terminal communicator to receive recognition information when the in-vehicle device detects a vehicle present location of the vehicle, acquire detection information on an object existing in a vicinity of the vehicle, generate the recognition information including position information on the object based on the vehicle present location and the detection information on the object, and deliver the recognition information;
• a terminal present location detector to detect a terminal present location of the mobile terminal device;
• a terminal information presenter to present information;
• and
• a terminal controller to judge whether the in-vehicle device recognizes existence of a first object equipped with the mobile terminal device or not based on the terminal present location and the recognition information received by the terminal communicator, make the terminal information presenter present that the in-vehicle device recognizes the first object when the terminal controller judges that the in-vehicle device recognizes the existence of the first object, and make the terminal communicator transmit existence notification information to the in-vehicle device when the terminal controller judges that the in-vehicle device does not recognize the existence of the first object.

A recognition support system comprising:

• an in-vehicle device installed in a vehicle including a detection unit for detecting an object;
• and
• a mobile terminal device to perform communication with the in-vehicle device, wherein
• the in-vehicle device includes:
• a vehicle exterior communicator to perform wireless communication;
• an in-vehicle detector to detect a vehicle present location of the vehicle;
• a vehicle interior communicator to acquire detection information on the object from the detection unit;
• and
• an in-vehicle controller to generate recognition information including position information on the object based on vehicle position information indicating the vehicle present location and the detection information on the object and make the vehicle exterior communicator deliver the recognition information, and
• the mobile terminal device includes:
• a terminal communicator to perform wireless communication;
• a terminal present location detector to detect a terminal present location of the mobile terminal device;
• a terminal information presenter to present information;
• and
• a terminal controller to judge whether the in-vehicle device recognizes existence of a first object equipped with the mobile terminal device or not based on the terminal present location and the recognition information received by the terminal communicator, make the terminal information presenter present that the in-vehicle device recognizes the first object when the terminal controller judges that the in-vehicle device recognizes the existence of the first object, and make the terminal communicator transmit existence notification information to the in-vehicle device when the terminal controller judges that the in-vehicle device does not recognize the existence of the first object.

A recognition support method in a system including an in-vehicle device that is installed in a vehicle including a detection unit for detecting an object and a mobile terminal device that includes a terminal information presenter that presents information and performs communication with the in-vehicle device, the recognition support method comprising:

• detecting a vehicle present location of the vehicle, acquiring detection information on the object from the detection unit, generating recognition information including position information on the object based on the vehicle present location and the detection information on the object, and delivering the recognition information, by the in-vehicle device;
• and
• receiving the recognition information, detecting a terminal present location as a present location of the mobile terminal device, judging whether the in-vehicle device recognizes existence of a first object equipped with the mobile terminal device or not based on the terminal present location and the received recognition information, presenting that the in-vehicle device recognizes the first object by using the terminal information presenter when the mobile terminal device judges that the in-vehicle device recognizes the existence of the first object, and transmitting existence notification information to the in-vehicle device when the mobile terminal device judges that the in-vehicle device does not recognize the existence of the first object, by the mobile terminal device.

A computer readable medium storing a recognition support program for causing an in-vehicle device, which is installed in a vehicle including a detection unit for detecting an object and performs communication with a mobile terminal device including a terminal information presenter that presents information, to execute:

• a process of detecting a vehicle present location of the vehicle;
• a process of acquiring detection information on the object from the detection unit;
• a process of generating recognition information including position information on the object based on vehicle position information indicating the vehicle present location and the detection information on the object and delivering the recognition information from the in-vehicle device;
• and
• a process of receiving existence notification information transmitted from the mobile terminal device when the mobile terminal device receiving the recognition information judges that the in-vehicle device does not recognize existence of a first object equipped with the mobile terminal device,
• wherein the recognition information is information for making the terminal information presenter present that the in-vehicle device recognizes the first object when the mobile terminal device receiving the recognition information judges that the in-vehicle device recognizes the existence of the first object.
