The voice data acquisition unit 15 includes a microphone provided in the vehicle interior and acquires the utterance of the occupant.
The communication unit 16 is connected to the network (Internet) 13 and performs data communication with the server 31 of the cloud service provider via the network 13.

The controller 17 is composed of, for example, a microcomputer and executes a vehicle diagnosis process described later.
The information transmission unit 18 includes a touch panel and a speaker, and transmits various information to the driver. The touch panel is a device that combines a touch-type input device and a liquid crystal panel, displays various information in response to a command from the controller 17, and when the driver touches the touch surface of the liquid crystal panel, the touch panel is displayed. The position information is input to the controller 17. For example, various inputs are performed by touching symbols and characters displayed on the liquid crystal panel. In addition, various information is output by voice by the speaker.

The controller 17 includes a primary diagnosis unit 21, a sensing determination unit 22, a secondary diagnosis request unit 23, and a secondary diagnosis result receiving unit 24.
The primary diagnosis unit 21 makes a primary diagnosis as to whether or not there is an abnormality in the vehicle according to the first vehicle data acquired by the vehicle information acquisition unit 14 and the utterance of the occupant acquired by the voice data acquisition unit 15. The first vehicle data is, for example, various fail signals, and the primary diagnosis according to the first vehicle data is a simple diagnosis for checking the presence or absence of an abnormality.
When the primary diagnosis unit 21 makes a primary diagnosis that there is an abnormality, the detection determination unit 22 determines whether or not the abnormality is perceptible to the driver and affects the running of the vehicle.

When the detection and determination unit 22 determines that the driver can detect the abnormality, the secondary diagnosis request unit 23 transmits the second vehicle data to the external server 31 via the communication unit 16 and also transmits the second vehicle data to the external server 31. Request a secondary diagnosis of the details of the anomaly according to the second vehicle data. On the other hand, when the detection determination unit 22 determines that the driver cannot detect the abnormality, it does not transmit the second vehicle data to the server and does not request the secondary diagnosis.
The secondary diagnosis result receiving unit 24 receives the diagnosis result of the secondary diagnosis from the server 31 via the communication unit 16.

A server 31 of a cloud service provider that provides software functions, application execution platform functions, hardware and infrastructure functions is connected to the network 13.

Send. The second vehicle data is more than the first vehicle data or different from the first vehicle data, and is data necessary for making a detailed diagnosis.
The support unit 33 supports the user in requesting the help of the road service or making a reservation for maintenance and warehousing from the store according to the diagnosis result of the secondary diagnosis unit 32.

Next, the vehicle diagnosis process executed by the controller 17 will be described.
FIG. 2 is a flowchart showing a vehicle diagnosis process on the vehicle side in the first embodiment.
In step S101, the primary diagnosis is performed according to the first vehicle data. Specifically, a simple primary diagnosis is performed according to various fail signals and utterances of occupants. The diagnosis according to the occupant's utterance is, for example, natural voice recognition (VOC: Voice Of the Customer) to recognize the occupant's conversation and detect an utterance complaining of a malfunction of the air conditioner or the heater.
In the following step S102, it is determined whether or not an abnormality is detected as a result of the primary diagnosis. When no abnormality is detected, the program returns to the predetermined main program as it is. On the other hand, when an abnormality is detected, the process proceeds to step S103.

In step S103, it is determined whether or not the secondary diagnosis flag has been reset to fs = 0. Here, when the secondary diagnosis flag is reset to fs = 0, it is determined that the secondary diagnosis has not been executed, and the process proceeds to step S104. On the other hand, when the secondary diagnosis flag is set to fs = 1, it is determined that the secondary diagnosis has been executed, and the process proceeds to step S122.
In step S104, it is determined whether or not the abnormality detected by the primary diagnosis is perceptible to the driver. Here, when it is determined that the driver can detect it, the process proceeds to step S105. Abnormalities that can be detected by the driver are abnormalities such as the warning light turning on or blinking, and abnormalities (malfunctions) in the air conditioner, heater, and the like. On the other hand, when it is determined that the driver cannot detect it, the process proceeds to step S106.

In step S105, it is determined whether or not the abnormality detected by the primary diagnosis affects the traveling of the vehicle. Here, if the content does not immediately affect the running of the vehicle, the process proceeds to step S106. Abnormalities that do not immediately affect the running of the vehicle are controls that operate only when a specific event occurs, such as anti-skid control (ABS), traction control (TCS), and stability control (VDC: Vehicle Dynamics Control). The system is abnormal. On the other hand, if the content immediately affects the running of the vehicle, the process proceeds to step S109. Abnormalities that immediately affect the running of the vehicle are abnormalities in engine oil pressure, brake system, charging system, exhaust temperature, and the like.

In step S106, it is determined whether or not the number of days until the periodic inspection is within a predetermined number of days (several days). Here, when the number of days until the periodic inspection is longer than the predetermined number of days, it is determined that there is a certain period until the periodic inspection, and the process proceeds to step S107. On the other hand, when the number of days until the periodic inspection is within a predetermined number of days, it is determined that the periodic inspection is near, and the program returns to the predetermined main program as it is.
In step S107, it is determined whether or not the traveling has been completed. For example, when the shift position is changed from the drive range to the parking range and the parking brake is activated, it is determined that the running is completed. Here, when it is determined that the traveling has been completed, the process proceeds to step S108. On the other hand, when it is determined that the running has not been completed, the program returns to the predetermined main program as it is.

In step S108, a command is output to the information transmission unit 18, the diagnosis result of the primary diagnosis is transmitted to the driver, and then the program returns to the predetermined main program.
On the other hand, in step S109, a command is output to the information transmission unit 18 and the diagnosis result of the primary diagnosis is transmitted to the driver.
In the following step S110, the second vehicle data is transmitted to the external server 31 via the communication unit 16, and the secondary diagnosis of the details of the abnormality is requested according to the second vehicle data.

In the following step S111, it is determined whether or not the diagnosis result of the secondary diagnosis is received from the server 31 via the communication unit 16. Here, the process waits until the diagnosis result of the secondary diagnosis is received, and when the diagnosis result of the secondary diagnosis is received, the process proceeds to step S112.
In step S112, the secondary diagnostic flag is set to fs = 1.
In the following step S113, it is determined whether or not the vehicle can travel according to the diagnosis result of the secondary diagnosis. Here, when it is determined that the vehicle can travel, that is, the continuation of vehicle travel is acceptable, the process proceeds to step S114. On the other hand, when it is determined that the vehicle cannot travel, that is, the vehicle is requested to stop, the process proceeds to step S124.

In step S114, it is determined whether or not the vehicle is in the process of moving toward the destination. Here, when the movement is in progress, the process proceeds to step S115. On the other hand, when the movement is completed, that is, when the destination has arrived, the process proceeds to step S118.
In step S115, it is determined whether or not the current position of the vehicle is within a predetermined range of the destination. Here, when the current position of the vehicle is outside the predetermined range of the destination, it is determined that the vehicle is far from the destination, and the process proceeds to step S116. On the other hand, when the current position of the vehicle is within a predetermined range of the destination, it is determined that the vehicle is close to the destination, and the process proceeds to step S119.

In step S116, a command is output to the information transmission unit 18, and the diagnosis result of the secondary diagnosis and the action to be taken according to the diagnosis result are transmitted to the driver.
In the following step S117, the transmission flag is set to ft = 1 and then the process proceeds to step S119.
On the other hand, in step S118, it is determined whether or not the transmission flag is reset to ft = 0. Here, when the transmission flag is reset to ft = 0, it is determined that the diagnosis result of the secondary diagnosis has not yet been transmitted to the driver, and the process proceeds to step S116. On the other hand, when the transmission flag is set to ft = 1, it is determined that the diagnosis result of the secondary diagnosis has already been transmitted to the driver, and the process proceeds to step S119.

In step S119, it is determined whether or not the transmission flag is set to ft = 1. Here, when the transmission flag is reset to ft = 0, it is determined that the diagnosis result of the secondary diagnosis has not yet been transmitted to the driver, and the program returns to the predetermined main program as it is. On the other hand, when the transmission flag is set to ft = 1, it is determined that the diagnosis result of the secondary diagnosis has already been transmitted to the driver, and the process proceeds to step S120.
In step S120, it is determined whether or not the vehicle is stopped. For example, when the shift position is changed from the drive range to the neutral range or the parking range and the parking brake is activated, it is determined that the vehicle is stopped. Here, when the vehicle is not stopped, the program returns to the predetermined main program as it is. On the other hand, when the vehicle is stopped, the process proceeds to step S121.

In step S121, the vehicle returns to the predetermined main program after reserving the maintenance and warehousing of the vehicle by the cloud service using the data communication with the support unit 33. Here, the maintenance warehousing reservation is made in consideration of the maintenance factory schedule, the inventory status of parts, the driver's schedule, etc., and requesting the driver's selection or consent.
On the other hand, in step S122, it is determined whether or not the maintenance warehousing of the vehicle has been reserved. Here, when the maintenance warehousing has not been reserved yet, the process proceeds to step S114. On the other hand, when the maintenance warehousing has already been reserved, the process proceeds to step S123.
In step S123, for example, when the maintenance warehousing date is approaching, a command is output to the information transmission unit 18, the driver is notified of the maintenance warehousing schedule, and then the program returns to the predetermined main program. ..

On the other hand, in step S124, a command is output to the information transmission unit 18, and the diagnosis result of the secondary diagnosis and the action to be taken according to the diagnosis result are transmitted to the driver. Here, the driver is urged to stop the vehicle immediately.
In the following step S125, the cloud service using the data communication with the support unit 33 requests the help of the road service and then returns to the predetermined main program.
When the maintenance of the vehicle is completed and the abnormality is resolved, the secondary diagnosis flag is reset to fs = 0 and the transmission flag is reset to ft = 0.
The above is the vehicle diagnosis process on the vehicle side.

Next, the vehicle diagnosis process executed by the server 31 will be described.
FIG. 3 is a flowchart showing the vehicle diagnosis process on the server side in the first embodiment.
In step S131, it is determined whether or not the request for the secondary diagnosis is received from the vehicle-mounted system 12 together with the second vehicle data. Here, when the request for the secondary diagnosis is not received, the program returns to the predetermined main program as it is. On the other hand, when the request for the secondary diagnosis is received, the process proceeds to step S132.
In step S132, a secondary diagnosis is performed for the details of the anomaly according to the second vehicle data.
In the following step S133, the diagnosis result of the secondary diagnosis is transmitted to the in-vehicle system 12, and then the program returns to the predetermined main program.
The above is the vehicle diagnosis process on the server side.

《Action》
Next, the operation of the first embodiment will be described.
It is conceivable to use a cloud service that uses the Internet to diagnose the vehicle, but if all the details are performed using the cloud service, the communication load, including communication charges, will increase. Further, even if there is an abnormality that does not immediately affect the vehicle running, it may be troublesome for the user to perform a detailed diagnosis and transmit the diagnosis result one by one.

Therefore, first, a simple primary diagnosis is performed by the primary diagnosis unit 21 of the in-vehicle system 12 (step S101), and when an abnormality is detected in this primary diagnosis (the determination in step S102 is “Yes”), the abnormality is detected. Determine if it is perceptible to the driver. Then, only when it is determined that the driver can detect it and that it affects the driving of the vehicle (the determinations in steps S104 and S105 are both "Yes"), a secondary diagnosis is requested using the cloud service accompanied by data communication. (Step S110). When the secondary diagnosis unit 32 of the server 31 receives the request from the in-vehicle system 12 (the determination in step S131 is “Yes”), the secondary diagnosis unit 32 executes the secondary diagnosis for examining the details of the abnormality according to the second vehicle data (the determination in step S131 is “Yes”). Step S132), the diagnosis result is transmitted to the in-vehicle system 12 (step S133). On the other hand, when it is determined that the driver cannot detect the vehicle or does not immediately affect the driving of the vehicle (the determination in step S104 or S105 is "No"), the second vehicle data transmission and the request for the secondary diagnosis are not executed. ..

In other words, the secondary diagnosis accompanied by data communication is performed after considering the situation and importance such as whether the content is perceptible to the driver and whether the content immediately interferes with the driving of the vehicle. Decide whether to do it. Therefore, the communication charge and the communication load can be suppressed as compared with the case where the vehicle diagnosis always involves data communication. Further, if the content is minor so that the driver does not notice it easily or does not immediately affect the vehicle running, the troublesomeness can be reduced by omitting the detailed diagnosis.

In addition, information is transmitted to the driver according to the judgment result of whether or not the abnormality can be detected by the driver. Specifically, the number, contents, timing, etc. of information transmission are changed according to the judgment result of whether or not the information can be detected.
First, when it is determined that the abnormality can be detected by the driver, the diagnosis result of the primary diagnosis is transmitted to the driver (step S109), and then after the secondary diagnosis, it is taken according to the diagnosis result of this secondary diagnosis. Communicate the action to be taken to the driver (step S116). In this way, by guiding the diagnosis result of the primary diagnosis, then the diagnosis result of the secondary diagnosis, and the measures to be taken accordingly, the driver feels more secure.

When the vehicle arrives at the destination soon (the determination in step S115 is “Yes”), the diagnosis result of the secondary diagnosis is not transmitted, and after arriving at the destination (the determination in step S114 is “No”). "), Communicate the diagnosis result of the secondary diagnosis. In this way, when you are moving toward your destination and are about to arrive at your destination, by refraining from communicating the diagnosis results, you should concentrate on driving until you reach your destination without being distracted. Can be done. Then, by transmitting the diagnosis result after arriving at the destination, the diagnosis result can be received more calmly. However, if it takes a while to arrive at the destination (the determination in step S115 is "No"), it is necessary to call attention frankly, so the diagnosis result is transmitted. This improves the confidence in the vehicle diagnostic system.

On the other hand, when it is determined that the driver cannot detect the vehicle or does not immediately affect the driving of the vehicle (the determination in step S104 or S105 is "No"), only the diagnosis result of the primary diagnosis is transmitted to the driver (step S108). .. As a result, the driver can understand that the vehicle diagnostic system properly grasps even minor contents that are difficult for the driver to notice or that do not immediately affect the driving of the vehicle, which gives a sense of security. And reliability is improved.
When the periodic inspection is near (the determination in step S106 is “Yes”), the diagnosis result is refrained from being transmitted. In this way, if it is clear that maintenance and inspection will be carried out in the near future and repairs will be carried out, there is no problem in refraining from transmitting the diagnosis result, and the troublesomeness can be further reduced.

Further, when the vehicle is traveling (the determination in step S107 is “No”), the diagnosis result of the primary diagnosis is not transmitted, and after the traveling is completed (the determination in step S107 is “Yes”), the primary diagnosis is performed. Communicate the diagnosis results. In this way, while the vehicle is traveling, by refraining from transmitting the diagnosis result, it is possible to concentrate on driving until the end of the traveling without being distracted. Then, by transmitting the diagnosis result after the running is completed, the diagnosis result can be received more calmly.

In addition, if a secondary diagnosis is made, it will affect the running of the vehicle, so even if the continuation of the running of the vehicle is allowed, it is necessary to promptly maintain and store the vehicle. Therefore, after transmitting the diagnosis result of the secondary diagnosis (the determination in step S119 is “Yes”), the cloud service is used to make a reservation for maintenance and warehousing (step S121). As a result, prompt maintenance and warehousing is promoted, and convenience is improved. At this time, the maintenance warehousing reservation is made when the vehicle is stopped (because the driver's selection or consent will be requested in consideration of the maintenance shop schedule, parts inventory status, driver's schedule, etc. The determination in step S120 is “Yes”). This allows you to focus on driving without distracting your attention.

After making a reservation for maintenance and warehousing (the determination in step S122 is “Yes”), a reminder is performed at any time (step S123). This prevents accidental forgetting of the warehousing schedule and improves convenience.
On the other hand, as a result of the secondary diagnosis, it may be diagnosed that the vehicle cannot run, and the vehicle may be required to stop. In this case, since it is necessary to stop the vehicle promptly, the driver is notified to that effect (step S124). Further, the cloud service is used to request the help of the road service (step S125). As a result, prompt road service can be received and convenience is improved.
