Title: VEHICLE SYSTEM, METHOD OF PROCESSING VEHICLE INFORMATION, RECORDING MEDIUM STORING A PROGRAM, TRAFFIC SYSTEM, INFRASTRUCTURE SYSTEM, AND METHOD OF PROCESSING INFRASTRUCTURE INFORMATION
Abstract: A vehicle system includes an obtainment unit that obtains first blind spot information from an infrastructure system having an infrastructure sensor detecting a surrounding object, the first blind spot information indicating a blind spot region due to the object observed from the infrastructure sensor, and a detection recognizer that generates second blind spot information indicating a blind spot region due to the object observed from an in-vehicle sensor detecting the object. The detection recognizer has a combination unit that outputs common blind spot information indicating a first common blind spot region common to the blind spot regions based on the first blind spot information and the second blind spot information to an external device.

Claims: number: 1
text: A vehicle system comprising:
number: 2
text: The vehicle system according to Claim 1, wherein
the operations further include controlling running of a vehicle in accordance with the common blind spot information.
number: 3
text: The vehicle system according to Claim 2, wherein
the operations further include
determining whether a size of the first common blind spot region is larger than a predetermined size, and
number: 4
text: The vehicle system according to Claim 2, wherein
the operations further include
extracting an attention region for controlling the vehicle in accordance with at least a running direction and a speed of the object, and
stopping the vehicle from running when a second common blind spot region common to the blind spot region due to the object and the attention region occurs when observed from the in-vehicle sensor.
number: 5
text: The vehicle system according to Claim 2 further comprising a second storage that stores road atlas information for enabling the vehicle to run, wherein
the operations further include
at least superimposing the first blind spot information and the second blind spot information onto the road atlas information.
number: 6
text: The vehicle system according to Claim 3, wherein
the operations further include
estimating a predicted trajectory from when the vehicle starts a predetermined running to when the vehicle finishes the predetermined running, and
determining whether an estimated arrival-predicted period until another object reaches the predicted trajectory is longer than an estimated passage period until the vehicle finishes passing the predicted trajectory, and
allowing the vehicle to run when the arrival-predicted period is longer than the passage period, and
stopping the vehicle from running when the arrival-predicted period is equal to or shorter than the passage period.
number: 7
text: The vehicle system according to Claim 1, wherein
the operations further include
obtaining first object information on the object observed from the infrastructure sensor,
outputting second object information on the object observed from the in-vehicle sensor, and
combining the first object information and the second object information.
number: 8
text: A method of processing vehicle information comprising:
number: 9
text: A non-transitory computer-readable recording medium storing a program, wherein
the program, when executed in a computer, causes the computer to execute operations including:
number: 10
text: A traffic system comprising:
number: 11
text: The vehicle system according to Claim 10, wherein
the first operations further include
calculating a speed of another object presumed to be in the blind spot region due to the object, in accordance with a predetermined period for which the infrastructure sensor performs detection and a length of the blind spot region in a depth direction in which the object is observed from the infrastructure sensor, and
outputting speed information indicating the speed to the vehicle.
number: 12
text: An infrastructure system that communicates with a vehicle system comprising:
number: 13
text: The infrastructure system according to Claim 12, wherein
the predetermined period is a detection period between a first time point and a second time point at each of which the object is detected, and
the length of the blind spot region is a sum of a distance moved by the object during the detection period and a length of the blind spot region at the first time point.
number: 14
text: The infrastructure system according to Claim 12, wherein
the predetermined period is a sampling cycle in which the infrastructure sensor performs detection periodically.
number: 15
text: A method of processing infrastructure information comprising:
