The user information processing unit 14 acquires information on the information terminal 30 used by the user from the used terminal information storage unit 14a. In addition, the user information processing unit 14 acquires vehicle specifying information that can be used by the user from the vehicle specifying information storage unit 14b.

Here, it is assumed that the notification system 1 according to the embodiment is introduced to a vehicle usable by the user in order to determine whether or not the vehicle is usable. As the vehicle that can be used by the user, for example, a case where a plurality of vehicles are owned by an individual or a family is assumed. In the embodiment, a case where two vehicles A and B are owned and the vehicle A is used preferentially will be described as an example.

The route search unit 15 has a function of performing a route search based on map information stored in the map information storage unit 15a, traffic information stored in the traffic information storage unit 15b, and position information, and determining a travel route. . The traffic information storage unit 15b includes, for example, traffic jam information, traffic stop information, weather information, or the like as traffic information, which is acquired through the communication network 40, FM broadcasting, or the like. The destination and arrival time are acquired from the scheduler 13. Further, the route search unit 15 includes a position detection unit (not shown), and has a function of specifying the position of the vehicle 20 using radio waves from a satellite such as GPS. The position detection may be performed by WiFi (registered trademark) or an autonomous sensor.

The center 10, the vehicle 20, and the information terminal 30 transmit / receive information to / from each other by connecting via the transmission /

reception units

16, 25, 30a and the communication network 40, respectively. The communication network 40 is, for example, an Internet communication network, and is configured to be capable of wired connection or wireless connection with the transmission /

reception units

16, 25, and 30a. The control unit 17 is a control unit that controls the functions of the center 10 in an integrated manner, and is an electronic control unit that is mainly configured by a computer including a CPU, a ROM, a RAM, an I / O, and the like.

The center 10 is provided with the main functions of the notification system 1 and is constructed so that the resources of the vehicle 20 and the information terminal 30 are not used when the notification system 1 is executed. Accordingly, since the power of the vehicle 20 is not used when the vehicle 20 is turned off (hereinafter referred to as IG-OFF), the vehicle 20 is not burdened, and the battery 20 can be prevented from running out.

The vehicle 20 includes an information processing unit 22, an ECU 23, a sensor 24, a transmission / reception unit 25, and a navigation unit 21, which are connected by a communication network 26 that is an in-vehicle LAN. The navigation 21 includes a navigation ECU (not shown) and has a function of searching and guiding the travel route of the vehicle 20. The information processing unit 22 includes a plurality of ECUs 23 and a plurality of sensors 24. The sensor 24 is connected to the ECU 23, and the ECU 23 is connected to the information processing unit 22. The sensor data measured by the sensor 24 is subjected to predetermined processing by the ECU 23 and transmitted to the information processing unit 22.

The ECU (Electronic Control Unit) 23 is an electronic control device mainly composed of a computer including a CPU, ROM, RAM, I / O and the like. Examples of the ECU 23 include an engine ECU, an accelerator ECU, a brake ECU, and a steering ECU. Although FIG. 2 illustrates a configuration in which one sensor 24 is connected to one ECU 23, this is an example and there is no intention to limit to this configuration.

Examples of the sensor 24 include various sensors such as a tire pressure sensor, a gasoline meter, an engine oil meter, a brake oil meter, a power steering oil meter, and a battery voltmeter. Here, the tire pressure sensor is monitored by, for example, TPMS (Tire Pressure Monitoring System). In the TPMS, the tire pressure sensor is wirelessly connected to the ECU 23 by a short-range wireless connection, and the air pressure data detected by each sensor 24 is acquired.

Since each air pressure sensor is assigned an ID that can identify the air pressure sensor, it is possible to identify the tire and the mounting location where each air pressure sensor is mounted, and to individually monitor the air pressure of each tire. . Further, by providing a pneumatic sensor for each of the summer tire and the winter tire, for example, it is possible to determine whether the summer tire is installed or the winter tire is installed.

The ECU 23 receives various sensor data from each sensor 24 and transmits it to the information processing unit 22. The information processing unit 22 that has acquired the sensor data performs a predetermined process on the sensor data and generates vehicle information. Thereafter, the generated vehicle information is transmitted to the transmission / reception unit 16 via the transmission / reception unit 25 and the communication network 40, and stored in the vehicle information storage unit 11a. The vehicle information includes sensor data such as tire air pressure, gasoline amount, engine oil amount, brake oil amount, power steering oil amount, and battery voltage.

It should be noted that a failure diagnosis unit may be provided in the vehicle 20 so that the vehicle 20 performs a failure diagnosis of the vehicle 20 based on the sensor data. In this case, the failure diagnosis result is transmitted from the vehicle 20 to the center 10, and the vehicle 20 determines the notification content according to the received failure diagnosis result, but performs processing using the battery power supply of the vehicle 20. When IG-OFF, the battery may run out. For this reason, in the embodiment, the failure diagnosis unit 11 is provided in the center 10.

The information terminal 30 includes a transmission / reception unit 30a, a position detection unit 30b, and an input / output unit 30c. The transmission / reception unit 30a is a communication device for wirelessly connecting to the center 10 and the vehicle 20 via the communication network 40, and the position detection unit 30b uses radio waves from a satellite such as GPS of the information terminal 30 to It has a function to specify the position. The identified location information of the information terminal 30 is transmitted to the route search unit 15 via the transmission / reception unit 30 a of the information terminal 30 and the reception unit 16 of the center 10. Thereby, the route search unit 15 can specify the position of the information terminal 30.

The input / output unit 30c includes, for example, a display device such as a liquid crystal display or an organic EL display, and a touch position detection device that detects a touched finger position, and the display device and the touch input unit are arranged to overlap each other. It is. As a result, it is possible to detect the pressing position of the finger on the keyboard, buttons, and the like displayed in software on the input / output unit 30c. Thereby, the user can input schedule information, for example.

As shown in FIG. 2, in the notification system 1, processing is executed as follows. Here, the case where there are two vehicles A and B as vehicles that can be used by the user will be described as an example. Furthermore, when there is a third and fourth vehicle, the vehicle C and the vehicle D may be processed according to the handling of the vehicle B. Moreover, the arrow in FIG. 2 has shown the moving direction of information.

In addition, here, description will be made assuming that the vehicle A is used preferentially. The usage priority order of the vehicles A and B may be registered in advance by the user in the vehicle specifying information storage unit 14b of the center 10, or the center 10 analyzes the usage status of the vehicles A and B and the vehicle is frequently used. You may set to select. Further, the vehicle may be determined according to the destination or the like. For example, a minivan may be selected for long distances, a compact car for short distances, a four-wheel drive vehicle for going to mountainous areas, and a vehicle equipped with winter tires if there is snowfall information. .

First, as advance preparation, a user registers a schedule using the information terminal 30 (S1), and the schedule information is stored in the information terminal 30 (S2). The center 10 appropriately communicates with the information terminal 30, acquires the schedule information stored in the information terminal 30, and the acquired schedule information is stored in the schedule information storage unit 13a of the center 10 (S3). Further, the schedule information may be stored in, for example, another server (not shown). In this case, the center 10 may acquire the schedule information from the other server.

Further, the center 10 acquires the vehicle information of the vehicle 20 and the vehicle B here (S4) and stores them in the vehicle information storage unit 11a. The acquisition of the vehicle information may be performed at any time, but for example, the vehicle information acquisition process can be set to be executed during the previous operation or when the vehicle system is shut down at the end of the previous operation. The vehicle information acquisition from the vehicle 20 may be performed when the vehicle 20 is traveling, or when the vehicle is a hybrid vehicle, when charging or traveling, in consideration of preventing the battery of the vehicle 20 from running out.

Further, the center 10 acquires traffic information via the communication network 40 (S5) and stores it in the traffic information storage unit 15b. This traffic information is updated every predetermined time, and the latest traffic information is stored in the traffic information storage unit 15b. Information acquired by the traffic information storage unit 15b may include weather information such as weather forecasts, warnings, and warnings. The traffic information may include data such as a unique traffic jam prediction.

Next, a notification content determination process is executed in the center 10 (S6). The notification content determination process will be described later with reference to FIG. The notification content is determined by the notification content determination process. The contents of the notification include the departure time, the vehicle 20 to be used, in this case, the vehicle A or the vehicle B, for example, the route to the destination via the repair facility, the alternative moving means and the route thereof.

The center 10 transmits notification information including the notification content to the information terminal 30 (S7), and the information terminal 30 displays the transmitted notification content (S8). The user browses the notification content displayed on the information terminal 30 (S9). Thereby, the user can recognize the time to depart, the vehicle 20 to be used, the route information to the destination, or the alternative moving means and its route. Note that the timing at which the center 10 transmits the notification information to the information terminal 30 may be notified in advance by taking into consideration the preparation time required until the user departs.

Also, even if the center 10 determines that repair is necessary, if it is determined that the vehicle 20 can be moved, information about the vehicle A or vehicle B to be used and, for example, via a repair facility Route information is transmitted (S10). Since the route via the repair facility is transmitted to the vehicle 20, the vehicle 20 may be directed to the destination via the repair facility according to the route guidance by the navigation 21 having the route information.

Next, the content of the notification content determination process will be described with reference to FIG. As shown in FIG. 3, when the notification content determination process is started, the failure diagnosis unit 11 of the center 10 determines whether or not the vehicle A needs repair (S21). Whether repair is necessary or not is determined by collating the vehicle information stored in the vehicle information storage unit 11a with the failure reference data stored in the failure reference data storage unit 11b.

Here, “failure” is a case where it is determined that repair is necessary, and means a vehicle state that hinders the continuation of vehicle travel. In this case, it is determined that a case where the vehicle cannot travel or is likely to be unable to travel immediately after the start of traveling corresponds to “failure”, and therefore, it is determined that repair is necessary (S21: YES). For example, when the battery is running out, the amount of gasoline stored in the gasoline tank is insufficient to reach the destination, the tire pressure is significantly reduced, and the vehicle is running safely. Such as when the volume has dropped significantly and it is expected that the engine will be destroyed if it starts running. If the engine oil amount falls within an allowable range, it does not fall under this failure.

If the failure diagnosis unit 11 determines that the repair is unnecessary (S21: NO), the route search unit 15 searches for the route and transmits the route information to the departure time calculation unit 12 (S22). The departure time calculation unit 12 acquires a route search result from the route search unit 15, an arrival time from the scheduler 13, and information on the used vehicle 20, here the vehicle A, from the user information processing unit 14. Based on these pieces of information, the departure time calculation unit 12 calculates the departure time that the user should leave (S23).

The control unit 17 determines the notification contents including the repair necessity result, the departure time, and the like, and generates notification information including these notification contents (S24). Thereafter, the notification system 1 notifies the user of the notification information (S7 in FIG. 2). Moreover, route information is transmitted to the navigation part 21 of the vehicle 20 (S10 of FIG. 2).

If the failure diagnosis unit 11 determines that repair is necessary (S21: YES), the failure diagnosis unit 11 confirms the content of repair, the time required for repair, and repair facility information (S25). Such information may be stored in the failure reference data storage unit 11b, or the latest information may be obtained by searching the Internet information via the communication network 40. The repair facility information includes, for example, business days, business hours, repairable items, etc. of a repair facility located within a radius of 5 km from the current location. Repair facilities include car dealers, car repair shops, and gas stations. If it is a specialized repair item specific to the vehicle, it is necessary to perform repairs at a repair facility such as an automobile dealer. For example, if you have tires that match puncture repair or size, etc. It can also be repaired at a gas station. Thus, the repair facility is selected according to the repair content.

As shown in S3 to S5 of FIG. 2, the failure diagnosis unit 11 has already acquired and held schedule information including destination information and estimated arrival time, traffic information, and the like. The failure diagnosis unit 11 determines whether or not repair is possible in consideration of schedule information, traffic information, repair contents, time required for repair, repair facility information, and the like (S26). Here, “unrepairable” means a failure state that makes it impossible to reach the destination at the arrival time according to the schedule information. If the destination cannot be reached at the arrival time, it is “repair impossible”. In addition, when repair is possible using a road service, such as tire puncture or battery exhaustion, for example, it is determined that repair is possible for replacement to a temper tire or jumping start (S26: YES), The vehicle cannot be self-propelled but can be repaired using the road service, and the notification content is determined so as to include the contact information of the road service that can be used (24), and the notification information including this is transmitted. Perform (S7). If the road service cannot be repaired, but it can be repaired at the repair facility, it is determined that the vehicle can be repaired (S26: YES), and the vehicle cannot move on its own, so the road service is used to move to the repair facility. The contents of the notification are determined so as to include the contact information of the load service that can be used and the available load service (24), and the notification information including this is transmitted (S7). In this case, the notification information is transmitted with the transmission time advanced in consideration of the time required for road service arrangement, repair work, and the like (S7).

For example, if the assumed departure time is outside the opening hours of the repair facility, and waiting for the opening time is not in time for the arrival time, it is determined that the repair is impossible. Even if it is within the business hours of the repair facility, it takes a long time for repair and if it is not in time for the scheduled arrival time, it is determined that the repair is impossible. If the failure diagnosis unit 11 determines that the repair is possible (S26: YES), the control unit 17 searches for a route through the repair in the repair facility (S27).

The searched route information is transmitted to the departure time calculation unit 12, and the processes of S23 and S24 are executed. Here, in the notification content information generated in S24, for example, when one hour is required for repair, the new departure time after the change set by setting the departure time one hour ahead is included. Further, the contents of repair, information on the repair facility, and route information via the repair facility may be included.

Next, when it is determined in S26 that repair is impossible (S26: NO), it is determined whether there is another vehicle that can be used by the user (S28). When there is another vehicle that can be used by the user (S28: YES), a notification content determination process is performed for the usable vehicle, here, vehicle B (S29). When the vehicle B is usable, that is, when the vehicle B does not require repair, the route from the storage location of the vehicle B is searched (S30), and when repair is necessary and repair is possible, the route via repair is searched. (S30) Subsequently, the processes of S23 and S24 are executed. For example, when the vehicle B is a vehicle that is normally used by the user's family, the usage trend identified by analyzing the usage status of the user and the schedule information of the family who normally uses the vehicle B are grasped. In this way, the availability of the day may be determined. In S24, the vehicle A needs to be repaired but cannot be repaired, the other vehicle that can be used here is the vehicle B, and the notification content including the searched route information, departure time, etc. is determined. Then, notification information including these notification contents is generated.

If the vehicle B cannot be repaired, it is determined that there is no other vehicle that can be used (S28: NO), the alternative moving means is searched (S31), and the route of the alternative moving means is searched (S32). Then, the process of S23 and S24 is implemented. Here, the notification information generated in S24 includes information such as the changed departure time, necessity of repair of the vehicle B, repair information, new route, alternative moving means, and the route.

When there is no other vehicle that can be used by the user, for example, when the user has only the vehicle A, and when the vehicle B cannot be repaired, it is determined that there is no other vehicle that can be used by the user. Then (S28: NO), the control unit 17 searches for alternative movement means (S31), and performs route search with this alternative movement means (S32). Alternative transportation means include trains, taxis, buses, airplanes, boats, walks, other transportation means, or combinations thereof. Then, the process of S23 and S24 is implemented. Here, the notification information generated in S24 includes information on the changed departure time, alternative moving means, and the route thereof. In this case, the notification content display browsing screen (S8) may be configured to display a button or the like for instructing to re-search for a further alternative moving device by disabling the moving device based on the notification content.

The notification system 1 may perform control such that the above processing is executed and notified, for example, two hours before the departure time described in the schedule information of the scheduler 13, and information necessary for determination is acquired. It may be controlled such that it is executed and notified each time it is performed. Further, even if the user selects a moving means different from the moving means based on the notification contents, it may be transmitted ahead of time until a time when the user can move with a margin. Note that the above notification to the user is performed at least before the changed departure time. For example, the control may be performed so that the notification is performed one hour before the changed departure time, the day before the scheduled date, or a few days before. The various processes described above are mainly performed in the center 10.

According to the notification system 1 described above, the following effects are obtained.
According to the notification system 1 according to the embodiment, when a failure that cannot reach the destination at the scheduled time registered in the schedule occurs in the vehicle used by the user, the notification system 1 repairs the failure. The user is notified of the departure time and the route via the repair in consideration of the time required. As a result, when a failure that makes it impossible to reach the destination at the scheduled time has occurred in the vehicle, the user has changed to an advance in consideration of the occurrence of a failure that requires repair and the time for repair. You will be notified of your departure time. For this reason, the user can arrive at the destination without delaying the scheduled time. With the above configuration, the notification system 1 calculates the departure time in consideration of the failure state of the vehicle 20, the time required for repair, and the user's schedule information, and notifies the user. Thereby, the notification system 1 which improved the user's convenience can be provided.

If the vehicle used by the user cannot be repaired, the notification system 1 notifies the user that a failure that cannot be repaired has occurred, the alternative moving means, and the departure time in the case of the alternative moving means. To do. Alternative transportation means include other vehicles, trains, taxis, buses, airplanes, boats, walks, and other transportation means available to the user. According to this, the notification system 1 can present an alternative moving means that takes into account the failure state of the vehicle and the user's schedule information, and can notify the user of the departure time when this alternative moving means is used. Therefore, the user can arrive at the destination without delaying the scheduled time. Thereby, the notification system 1 which improved the user's convenience can be provided.

Further, the failure diagnosis unit 11, the scheduler 13, the departure time calculation unit 12, and the control unit 17 are provided in a center configured to be connectable to a vehicle and an information terminal via a communication network. Since these controls and processes are executed mainly by the center 10, the vehicle 20 is not burdened even when the vehicle 20 is IG-OFF, and the battery of the vehicle 20 does not run out.
