<< First Embodiment >>
"Constitution"
FIG. 1 is a configuration diagram of a vehicle diagnostic apparatus according to the first embodiment.
The vehicle diagnostic apparatus 11 includes an in-vehicle system 12 and a network 13.
First, the in-vehicle system 12 includes a vehicle information acquisition unit 14, an audio data acquisition unit 15, a communication unit 16, a controller 17, and an information transmission unit 18.

The vehicle information acquisition unit 14 acquires vehicle information via an in-vehicle communication network (in-vehicle LAN) such as CSMA / CA multiplex communication (CAN: Controller Area Network) or Flex Ray. The vehicle information includes various fail signals.
The voice data acquisition unit 15 includes a microphone provided in the passenger compartment, and acquires the utterance of the occupant.
The communication unit 16 is connected to a 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 vehicle diagnosis processing described later.
The information transmission part 18 consists of a touch panel and a speaker, and transmits various information to a driver | operator. The touch panel is a device that combines a touch-type input device and a liquid crystal panel. When the driver touches the touch surface of the liquid crystal panel, the touch panel displays various types of information according to commands from the controller 17. 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. Also, various information is output by voice through a 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 reception unit 24.
The primary diagnosis unit 21 performs a primary diagnosis on 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 examining 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 the abnormality is perceptible to the driver and affects the driving of the vehicle.

The secondary diagnosis request unit 23 transmits the second vehicle data to the external server 31 via the communication unit 16 when the detection determination unit 22 determines that the abnormality can be detected by the driver. The secondary diagnosis is requested for details of the abnormality according to the second vehicle data. On the other hand, when it is determined by the detection determination unit 22 that the abnormality cannot be detected by the driver, the second vehicle data is not transmitted to the server and the secondary diagnosis is not requested.
The secondary diagnosis result receiving unit 24 receives the diagnosis result of the secondary diagnosis from the server 31 via the communication unit 16.

Connected to the network 13 is a server 31 of a cloud service provider that provides software functions, platform functions for executing applications, hardware and infrastructure functions.
The server 31 includes a secondary diagnosis unit 32 and a support unit 33.
The secondary diagnosis unit 32 receives the second vehicle data from the in-vehicle system 12, and when receiving a request for the secondary diagnosis, performs secondary diagnosis of the details of the abnormality and sends the diagnosis result to the in-vehicle system 12. Send. The second vehicle data is more than the first vehicle data or is different from the first vehicle data, and is necessary for making a detailed diagnosis.
The support unit 33 supports the user in that it requests a load service relief or makes a reservation for maintenance warehousing according to the diagnosis result of the secondary diagnosis unit 32.

Next, vehicle diagnosis processing executed by the controller 17 will be described.
FIG. 2 is a flowchart illustrating a vehicle diagnosis process on the vehicle side in the first embodiment.
In step S101, a primary diagnosis is performed according to the first vehicle data. Specifically, a simple primary diagnosis is performed in accordance with various fail signals, occupant utterances, and the like. Diagnosis according to the occupant's utterance is, for example, by recognizing the occupant's conversation by natural voice recognition (VOC: Voice Of the Customer) and detecting an utterance that appeals to malfunction of the air conditioner or heater.
In a succeeding 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 process 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 the secondary diagnosis flag is reset to fs = 0. Here, when the secondary diagnosis flag is reset to fs = 0, it is determined that the secondary diagnosis is not 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 perceive, the process proceeds to step S105. The abnormality that can be sensed by the driver is an abnormality such as a warning light being turned on or blinking, or an abnormality (malfunction) of an air conditioner or a heater. On the other hand, when it is determined that the driver cannot perceive, the process proceeds to step S106.

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

In step S106, it is determined whether or not the number of days until the regular inspection is within a predetermined number of days (several days). Here, when the number of days until the periodic inspection is larger 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 process returns to the predetermined main program as it is.
In step S107, it is determined whether or not the traveling is finished. For example, when the shift position is changed from the drive range to the parking range and the parking brake is operated, it is determined that the traveling is finished. Here, when it is determined that the traveling is finished, the process proceeds to step S108. On the other hand, when it is determined that the travel has not ended, the process 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 process 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 subsequent step S110, the second vehicle data is transmitted to the external server 31 via the communication unit 16, and a secondary diagnosis is requested for details of the abnormality according to the second vehicle data.

In a succeeding step S111, it is determined whether or not a 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. When the diagnosis result of the secondary diagnosis is received, the process proceeds to step S112.
In step S112, the secondary diagnosis flag is set to fs = 1.
In a succeeding 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 can be permitted, 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 moving toward the destination. Here, when it is in the middle of movement, the process proceeds to step S115. On the other hand, when the movement is completed, that is, when the vehicle has arrived at the destination, 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 subsequent 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 process 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 operated, it is determined that the vehicle is stopped. Here, when the vehicle is not stopped, the process 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 maintenance service storage of the vehicle is reserved by a cloud service using data communication with the support unit 33, and then the process returns to the predetermined main program. Here, in consideration of the schedule of the maintenance shop, the inventory status of the parts, the schedule of the driver, etc., the maintenance warehousing is reserved in response to the selection or consent of the driver.
On the other hand, in step S122, it is determined whether or not the vehicle maintenance warehousing has been reserved. If the maintenance warehousing has not yet been reserved, 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, if necessary, for example, when the date of maintenance warehousing approaches, a command is output to the information transmission unit 18 to notify the driver of the maintenance warehousing schedule and then return to a 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 prompted to stop the vehicle immediately.
In the subsequent step S125, the cloud service using data communication with the support unit 33 is requested to rescue 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, vehicle diagnosis processing executed by the server 31 will be described.
FIG. 3 is a flowchart showing a server-side vehicle diagnosis process in the first embodiment.
In step S131, it is determined whether a request for secondary diagnosis is received from the in-vehicle system 12 together with the second vehicle data. Here, when the secondary diagnosis request is not received, the process returns to the predetermined main program as it is. On the other hand, when the secondary diagnosis request is received, the process proceeds to step S132.
In step S132, a secondary diagnosis is executed for details of the abnormality in accordance with the second vehicle data.
In subsequent step S133, the diagnosis result of the secondary diagnosis is transmitted to the in-vehicle system 12, and then the process returns to the predetermined main program.
The above is the server-side vehicle diagnosis process.

<Action>
Next, the operation of the first embodiment will be described.
Although it is conceivable to perform vehicle diagnosis using a cloud service using the Internet, if all the details are performed using the cloud service, the communication load including the communication fee will increase. In addition, even if an abnormality does not immediately affect the vehicle running, it may be bothersome for the user to make 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). When an abnormality is detected in the primary diagnosis (determination in step S102 is “Yes”), the abnormality is detected. It is determined whether or not it can be sensed by the driver. Then, only when it is determined that it is perceptible to the driver and affects driving of the vehicle (both determinations in steps S104 and S105 are “Yes”), a secondary diagnosis is requested using a cloud service involving 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 performs a secondary diagnosis to check the details of the abnormality according to the second vehicle data ( In 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 it 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 secondary diagnosis request are not executed. .

  In other words, considering the situation and importance of whether or not the content is perceptible to the driver and whether or not the content immediately impedes driving of the vehicle, secondary diagnosis with data communication is performed. Decide whether to execute. Therefore, communication charges and communication load can be suppressed as compared with the case where vehicle diagnosis always involving data communication is executed. Further, if the content is so small that it is difficult for the driver to notice or the vehicle travel is not immediately affected, the troublesomeness can be reduced by omitting the detailed diagnosis.

In addition, information is transmitted to the driver according to the determination result as to whether or not an abnormality can be detected by the driver. Specifically, the number of times of information transmission, contents, timing, and the like are changed according to the determination result of whether or not it can be sensed.
First, when it is determined that an abnormality can be sensed by the driver, the diagnosis result of the primary diagnosis is transmitted to the driver (step S109), and after the secondary diagnosis, it is taken according to the diagnosis result of the secondary diagnosis. The behavior to be transmitted is transmitted to the driver (step S116). In this way, by guiding the diagnosis result of the primary diagnosis, the diagnosis result of the secondary diagnosis, and the actions to be taken in accordance with the diagnosis result in order, the driver can feel more secure.

  When the vehicle is about to arrive at the destination (step S115 is “Yes”), the diagnosis result of the secondary diagnosis is not transmitted and the vehicle arrives at the destination (the determination at step S114 is “No”). )) Communicate the diagnosis result of the secondary diagnosis. In this way, when you are moving towards your destination and you are about to arrive at your destination soon, focus on driving until you arrive at your destination without being distracted by refraining from communicating diagnostic results. Can do. 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 until the destination arrives (the determination in step S115 is “No”), it is necessary to alert frankly, so the diagnosis result is transmitted. Thereby, the reliability with respect to a vehicle diagnostic system improves.

On the other hand, when it is determined that the driver cannot perceive 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 diagnosis system properly understands even minor content that is difficult for the driver to notice or that does not immediately affect vehicle driving. And confidence is improved.
Note that when the periodic inspection is close ("Yes" in step S106), the diagnosis result is not transmitted. Thus, if it is clear that maintenance and inspection will be performed and repaired in the near future, there is no problem even if the diagnosis result is not transmitted, and the troublesomeness can be further reduced.

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

  Further, when the secondary diagnosis is performed, it means that the vehicle travel is affected. Therefore, even if the continuation of the vehicle travel is permitted, it is necessary to promptly store the vehicle. Therefore, after transmitting the diagnosis result of the secondary diagnosis (determination in step S119 is “Yes”), reservation of maintenance warehousing is performed using the cloud service (step S121). As a result, prompt maintenance is facilitated, and convenience is improved. At this time, considering the maintenance factory schedule, parts inventory status, driver's schedule, etc., the driver's selection or consent will be requested, so the maintenance warehousing reservation is made when the vehicle is stopped ( The determination in step S120 is “Yes”). This allows you to focus on driving without distracting your attention.

After making a reservation for maintenance warehousing (determination in step S122 is “Yes”), a reminder is performed as needed (step S123). This prevents inadvertently forgetting the warehousing schedule and improves convenience.
On the other hand, as a result of the secondary diagnosis, it is diagnosed that the vehicle cannot travel, and the vehicle may be requested to stop. In this case, since it is necessary to stop the vehicle promptly, this is transmitted to the driver (step S124). Further, the cloud service is used to request the load service (step S125). As a result, a quick road service can be received and convenience is improved.

<Modification>
In the first embodiment, when it is determined that the driver cannot detect the abnormality, the diagnosis result of the primary diagnosis is transmitted to the driver after the driving is finished. However, the present invention is not limited to this. The diagnosis result of the primary diagnosis may be transmitted to the driver before traveling. In any case, it is possible to concentrate on driving without distracting attention by refraining from transmitting diagnosis results during traveling.
In 1st Embodiment, although data communication with the server 31 is performed via the communication part 16 of the vehicle-mounted system 12, it is not limited to this.

In a succeeding step S202, it is determined whether or not a diagnostic result of the primary diagnosis is received from the server 31 via the communication unit 16. Here, the process waits until the diagnosis result of the primary diagnosis is received, and when the diagnosis result of the primary diagnosis is received, the process proceeds to step S102.
The above is the vehicle diagnosis process on the vehicle side.

FIG. 6 is a flowchart showing server-side vehicle diagnosis processing in the second embodiment.
Here, before the process of step S131 mentioned above, the process of new step S211-S213 is added.
In step S211, it is determined whether a primary diagnosis request is received from the in-vehicle system 12 together with the first vehicle data. If the primary diagnosis request has not been received, the process proceeds to step S131. On the other hand, when the primary diagnosis request is received, the process proceeds to step S212.
In step S212, primary diagnosis is performed to determine whether or not there is an abnormality in the vehicle according to the first vehicle data.
In subsequent step S213, the diagnosis result of the primary diagnosis is transmitted to the in-vehicle system 12, and then the process returns to the predetermined main program.
The above is the server-side vehicle diagnosis process.

<Action>
Next, the operation of the second embodiment will be described.
The in-vehicle system 12 requests a primary diagnosis using a cloud service with data communication (step S201). When the primary diagnosis unit 34 of the server 31 receives the request from the in-vehicle system 12 (the determination in step S211 is “Yes”), the primary diagnosis unit 34 performs a primary diagnosis as to whether there is an abnormality in the vehicle according to the first vehicle data. Then, the diagnosis result is transmitted to the in-vehicle system 12 (step S213).
In this way, the primary diagnosis unit 21 can be omitted from the in-vehicle system 12 by executing not only the secondary diagnosis but also the primary diagnosis using the cloud service.
In the second embodiment, the same effects as those in the first embodiment described above can be obtained, and detailed description thereof will be omitted.
