<First Embodiment>
[Configuration and basic operation]
(a) Vehicle Information Processing System FIG. 1 is a diagram showing the configuration of a vehicle information processing system according to a first embodiment of the present invention.

Referring to FIG. 1 , vehicle information processing system 301 includes one or more vehicles 101 , management server (management device) 121 , and radio base station device 161 . FIG. 1 shows one vehicle 101 as an example.

Vehicle 101 includes communication unit 11 , sensor 12 , transmission control unit 13 , and one or more functional units 14 . FIG. 1 shows one functional unit 14 as an example.

The sensor 12 is a radar device using millimeter waves, an imaging device, or LiDAR (Light Detection and Ranging) used for automatic driving. Output. The measurement data may be data indicating the measurement result itself, or may be data indicating a level or the like based on the measurement result.

The communication unit 11 transmits measurement data received from the sensor 12 via the radio base station device 161 according to a communication method such as a fifth generation mobile communication system (hereinafter referred to as “5G”) or LTE (Long Term Evolution). to the management server 121.

The transmission control unit 13 sets the amount of measurement data output by the sensor 12 per unit time. For example, the transmission control unit 13 sets the resolution of measurement data, sets the data format of measurement data, and sets the output frequency of measurement data from the sensor 12 to the communication unit 11 .

The functional unit 14 is a driving control device, an automatic driving ECU (Electronic Control Unit), or the like, and controls driving of the vehicle 101 . Specifically, the functional unit 14 includes an engine control device, an AT (Automatic Transmission) control device, a HEV (Hybrid Electric Vehicle) control device, a brake control device, a chassis control device, a steering control device, an instrument display control device, and the like. .

The management server 121 includes a communication unit 21 , an analysis unit 22 , a processing setting unit (setting unit) 23 and a determination unit 24 .

The communication unit 21 receives measurement data transmitted from each vehicle 101 via the radio base station device 161 and outputs the received measurement data to the analysis unit 22 .

The analysis unit 22 performs analysis processing for analyzing one or more pieces of measurement data received from the communication unit 21 . More specifically, the analysis unit 22 performs recognition processing for recognizing objects existing around the vehicle 101 as analysis processing based on one or more pieces of measurement data.

Specifically, the analysis unit 22 detects an object existing around the vehicle 101 based on one or more pieces of measurement data, and identifies the type of the detected object. Examples of object types include vehicles, bicycles, pedestrians, and signal lights. Further, when detecting a pedestrian, the analysis unit 22 can identify whether the pedestrian is an adult or a child, for example.

In addition, when the vehicle is detected, the analysis unit 22 further detects lamps such as brake lights and direction indicators of the vehicle, and confirms the lighting status of the lamps, thereby determining the running state of the vehicle. be able to. The running state of the vehicle is, for example, a parked state, a stopped state, a state in which the brake is applied, or a state before turning left or right.

In addition, the analysis unit 22 uses the result of the above-described recognition processing as analysis processing, for example, processing by machine learning, specifically, object recognition by a classification model according to the technique of deep learning. can be done.

Analysis unit 22 then transmits analysis data based on the result of analysis processing to one or more vehicles 101 via communication unit 21 and radio base station device 161 .

The communication unit 11 in each vehicle 101 receives the analysis data transmitted from the management server 121 via the radio base station device 161 and outputs the received analysis data to the function unit 14 . Based on the analysis data received from the communication unit 11, the function unit 14 performs control for automatic driving or safe driving support of the own vehicle 101, for example.

The determination unit 24 in the management server 121 determines the communication status of each vehicle 101 and outputs determination information indicating the determination result to the process setting unit 23 . The details of the determination of the communication status by the determination unit 24 will be described later.

The processing setting unit 23 sets the contents of analysis processing by the analysis unit 22 based on the judgment information received from the judgment unit 24 .

More specifically, when the process setting unit 23 receives determination information indicating that the communication status of a certain vehicle 101 is bad from the determination unit 24, the content of the analysis process based on the measurement data from the vehicle 101 is set to Set to the content appropriate for the few situations. Further, when the processing setting unit 23 receives determination information indicating that the communication status of a certain vehicle 101 is good from the determination unit 24, the content of the analysis processing based on the measurement data from the vehicle 101 is changed to the state where the amount of data is large. Set appropriate content. The details of the setting of the contents of the analysis processing by the processing setting unit 23 will be described later.

(b) Description of Problem It is assumed that the analysis unit 22 performs analysis processing (hereinafter referred to as “first analysis processing ). The first analysis processing is, for example, object recognition processing including detection of an object existing around the vehicle 101, identification of the type of the detected object, and determination of the running state of the detected vehicle.

With such a configuration, when the communication status of the vehicle 101 deteriorates and the data amount per unit time of the measurement data transmitted by the vehicle 101 to the management server 121 decreases, the analysis unit 22 performs the first analysis process. It may not be done correctly.

That is, even when the communication condition of the vehicle 101 is poor, the analysis unit 22 performs the same first analysis processing as when the communication condition is good. There is a possibility of erroneously recognizing the type of the detected object or erroneously determining the traveling state of the vehicle 101 .

On the other hand, the vehicle information processing system 301 according to the first embodiment of the present invention solves such problems by the following processing.

(c) Judgment of communication status (c-1) Judgment based on communication method Acquired from device 161 . Then, determination unit 24 confirms the communication method between vehicle 101 and radio base station device 161 based on the acquired communication information. Then, for example, the determination unit 24 determines that the communication condition is good when the communication method is 5G, and determines that the communication condition is bad when the communication method is LTE.

Further, determination unit 24 may determine the communication method between vehicle 101 and radio base station device 161 based on the position information of vehicle 101 .

For example, the vehicle 101 acquires its own position based on radio waves from GPS (Global Positioning System) satellites at predetermined intervals, and creates position information indicating the acquired position. Then, vehicle 101 transmits the created position information together with the measurement data to management server 121 via radio base station device 161 .

A storage unit (not shown) in the management server 121 stores, for example, a service area map indicating a communication method for each area.

The determination unit 24 receives the position information transmitted from the vehicle 101 via the communication unit 21 and the radio base station device 161, and based on the received position information and the service area map stored in the storage unit, the vehicle 101 and the The communication method between the radio base station apparatuses 161 is confirmed. Then, the determination unit 24 determines whether the communication status is good or bad according to the communication method.

Even in areas where the service area map indicates that the 5G communication system can be used, for example, the communication situation may be poor in places where it is difficult for wireless signals to reach spots where the building is an obstacle. Unfortunately, there may be spots that cannot use the 5G communication method. Therefore, the determination unit 24 may determine the communication status of the vehicle 101 based on the following information other than the communication method.

(c-2) Judgment Based on Signal Strength Judgment unit 24 confirms the strength of the signal transmitted and received between vehicle 101 and radio base station device 161, specifically, the strength of the radio signal including measurement data, etc. The communication status of the vehicle 101 may be determined.

For example, determination unit 24 acquires communication information indicating the signal strength of signals transmitted and received between vehicle 101 and radio base station device 161 from radio base station device 161 via communication unit 21 . Then, the determination unit 24 checks the signal strength based on the acquired communication information, and determines that the communication situation is bad when the signal strength remains below the threshold value Th1 for a predetermined period or longer. On the other hand, the determination unit 24 determines that the communication condition is good when the signal strength is equal to or greater than the threshold Th1, or when the state in which the signal strength is less than the threshold Th1 does not continue for a predetermined period or longer.

(c-3) Judgment Based on Communication Delay Time Judgment unit 24 confirms the communication delay time D1 between vehicle 101 and management server 121 via radio base station device 161 to determine the communication status of vehicle 101. You can judge.

For example, the determination unit 24 checks the delay time D1, which is the difference between the time stamp attached to the measurement data when it was transmitted from the vehicle 101 and the reception time of the measurement data in the communication unit 21 of the management server 121 .

Then, the determination unit 24 determines that the communication situation is bad when the state in which the delay time D1 is equal to or greater than the threshold Th2 continues for a predetermined period or longer. On the other hand, the determination unit 24 determines that the communication condition is good when the delay time D1 is less than the threshold Th2, or when the delay time D1 is equal to or greater than the threshold Th2 does not continue for a predetermined period of time.

Note that the determination unit 24 may comprehensively determine the communication status of the vehicle 101 using any one or more of the communication method, signal strength, and delay time D1.

(c-4) Estimation of Timing at which Communication Status Changes Based on position information and speed information of vehicle 101, determination unit 24 estimates the timing at which communication status changes to determine the communication status of vehicle 101. good too.

For example, vehicle 101 transmits position information and speed information to management server 121 via radio base station device 161 at predetermined intervals.

Determination unit 24 in management server 121 receives position information and speed information from vehicle 101 via radio base station device 161, and determines the traveling direction of vehicle 101, for example, based on the position information. Then, based on the received position information and speed information, the determined traveling direction, and the service map area, the determination unit 24 estimates the time until the position of the vehicle 101 moves out of the area where the 5G communication method can be used. can do.

Based on the estimated time, the determination unit 24 estimates the communication status change timing at which the communication status of the vehicle 101 changes. Further, the determination unit 24 determines the setting change timing, which is the timing at which the processing setting unit 23 should change the content of the analysis processing, based on the estimated communication situation change timing. The setting change timing may be the same as the communication situation change timing, or may be different from the communication situation change timing.

Then, the determination unit 24 outputs to the process setting unit 23 the determined setting change timing and determination information indicating the change in the communication status at the setting change timing.

(d) Setting the content of the analysis process (d-1) Setting the content of the analysis process based on the quality of the communication status The process setting unit 23 determines any one of the above (c-1) to (c-3). When determination information indicating the determination result obtained by the determination unit 24 is received from the determination unit 24, the contents of analysis processing by the analysis unit 22 are set.

For example, when the processing setting unit 23 receives determination information indicating that the communication condition of the vehicle 101 is bad from the determination unit 24, the processing setting unit 23 sets the content of the analysis processing by the analysis unit 22 to a content suitable for a situation in which the amount of data is small. . Hereinafter, the analysis processing whose contents are suitable for situations where the amount of data is small will be referred to as "second analysis processing".

That is, when the processing setting unit 23 receives determination information indicating that the communication condition of the vehicle 101 is bad from the determination unit 24 while the analysis unit 22 is performing the first analysis processing, the processing setting unit 23 performs the analysis processing by the analysis unit 22. The first analysis process is changed to the second analysis process. The second analysis processing includes, for example, recognition processing by a support vector machine, which is an example of machine learning, and object recognition processing limited to detection of objects existing around the vehicle 101 .

Further, when the processing setting unit 23 receives the judgment information indicating that the communication condition of the vehicle 101 is good from the judgment unit 24 while the analysis unit 22 is performing the second analysis processing, the processing setting unit 23 causes the analysis unit 22 to perform the analysis processing. The second analysis process is changed to the first analysis process.

In this way, the determination unit 24 determines the communication status of the vehicle 101 , and the processing setting unit 23 dynamically changes the contents of the analysis processing by the analysis unit 22 according to the determination result of the determination unit 24 .

Then, when the communication status of the vehicle 101 is good, the analysis unit 22 performs a first analysis process capable of obtaining an effective analysis result by automatic driving or safe driving assistance. On the other hand, when the communication condition of the vehicle 101 is poor, the analysis unit 22 performs the second analysis process using parameters different from those of the first analysis process, thereby reducing the possibility of obtaining an erroneous analysis result. .

(d-2) Setting the content of the analysis process at the setting change timing. Further, the process setting unit 23 receives the determination information indicating the setting change timing obtained by the determination process (c-4) from the determination unit 24. In this case, the content of analysis processing by the analysis unit 22 is set at the setting change timing.

For example, when the process setting unit 23 receives from the determination unit 24 the setting change timing and the determination information indicating that the communication status of the vehicle 101 is deteriorating at the setting change timing, the processing setting unit 23 performs analysis by the analysis unit 22 at the setting change timing. The processing is changed from the first analysis processing to the second analysis processing.

Further, when the process setting unit 23 receives from the determination unit 24 the setting change timing and determination information to the effect that the communication status of the vehicle 101 is improved at the setting change timing, the processing setting unit 23 performs analysis by the analysis unit 22 at the setting change timing. The process is changed from the second analysis process to the first analysis process.

(e) Setting the data amount of measurement data When the processing setting unit 23 in the management server 121 sets the content of the analysis processing based on the determination information received from the determination unit 24, the setting data based on the setting content is sent to the communication unit. 21 and radio base station device 161 to the vehicle 101 . The setting data may be data indicating specific contents of the analysis process, or data indicating whether the analysis process is set to the first analysis process or the second analysis process.

When the communication unit 11 in the vehicle 101 receives the setting data transmitted from the management server 121 via the radio base station device 161 , the communication unit 11 outputs the setting data to the transmission control unit 13 .

For example, when the transmission control unit 13 receives setting data indicating that the analysis process has been changed from the first analysis process to the second analysis process from the communication unit 11, the data per unit time of the measurement data output by the sensor 12 Set it to a smaller amount. Specifically, the transmission control unit 13 sets the output frequency of the measurement data output by the sensor 12 to be low, that is, sets the sensor 12 to output the measurement data after thinning, or sets the sensor 12 to output the measurement data. Setting is made so that the resolution is lowered for output, or setting is made so that the sensor 12 changes the data format of the measurement data.

Further, for example, when the transmission control unit 13 receives from the communication unit 11 the setting data indicating that the analysis process has been changed from the second analysis process to the first analysis process, the transmission control unit 13 transmits the measurement data output by the sensor 12 per unit time. set so that the amount of data in Specifically, the transmission control unit 13 sets the measurement data output by the sensor 12 to be output at a normal output frequency, that is, sets the sensor 12 to output the measurement data without thinning, or sets the sensor 12 to output the measurement data Setting is made so that the resolution of the data is increased, and the data format of the sensor 12 is changed.

In this manner, the transmission control unit 13 sets the data amount per unit time of the measurement data output by the sensor 12 according to the communication status of the vehicle 101, thereby allowing the sensor 12 to perform analysis processing by the management server 121. Measurement data can be transmitted with a suitable amount of data. In addition, since it is possible to avoid transmission of measurement data exceeding the content required for analysis processing by the management server 121, resources for calculation, storage, transmission, etc. of measurement data in the vehicle 101 can be saved.

Further, transmission control unit 13 may set the communication method between vehicle 101 and radio base station device 161 based on the setting data received from communication unit 11 .

For example, when the analysis unit 22 performs the second analysis process, even if the communication method between the vehicle 101 and the radio base station device 161 is LTE, the amount of data required for the second analysis process can be communicated. . Therefore, when the transmission control unit 13 receives setting data indicating that the analysis processing has been changed from the first analysis processing to the second analysis processing, the communication method between its own vehicle 101 and the radio base station device 161 is set to LTE. The setting for the communication unit 21 is performed so that

On the other hand, when the analysis unit 22 performs the first analysis process, the amount of data required for the first analysis process is large, so the communication method between the vehicle 101 and the radio base station device 161 is preferably 5G. Therefore, when the transmission control unit 13 receives the setting data indicating that the analysis process has been changed from the second analysis process to the first analysis process, the communication method between its own vehicle 101 and the radio base station device 161 is set to 5G. The setting for the communication unit 21 is performed so that

The setting data may indicate the communication method between vehicle 101 and radio base station device 161 . In this case, transmission control unit 13 sets the communication method between own vehicle 101 and radio base station device 161 to the communication method indicated by the setting data received from communication unit 11 .

Further, the processing setting unit 23 may be configured not to transmit setting data to the vehicle 101 . That is, even if the processing setting unit 23 in the management server 121 changes the contents of the analysis processing in the analysis unit 22, the measurement data transmitted from the vehicle 101 to the management server 121 via the radio base station device 161 per unit time data amount does not need to be changed.

Next, the analysis unit 22 in the management server 121 receives the measurement data transmitted from the sensor 12 via the wireless base station device 161 and the communication unit 21, and transmits the measurement data response to the received measurement data to the communication unit 21 and the wireless communication unit 21. The measurement data is transmitted to the vehicle 101, which is the transmission source of the measurement data, via the base station device 161 (step S12).

Next, analysis unit 22 performs, for example, detection of an object existing around vehicle 101, identification of the type of the detected object, and (step S13).

Next, analysis unit 22 transmits analysis data based on the result of the first analysis process to vehicle 101 via communication unit 21 and radio base station device 161 (step S14). Note that the analysis unit 22 may transmit the analysis data to a vehicle 101 other than the vehicle 101 that transmitted the measurement data.

Next, the judgment unit 24 in the management server 121 judges the communication status of the vehicle 101 based on the communication system between the vehicle 101 and the radio base station device 161, and sends judgment information indicating the judgment result to the processing setting unit 23.
