  According to this invention, the estimation means estimates the information requested based on the operation information and the running situation, and the information providing means provides information on the estimated information. Therefore, the passenger can automatically obtain necessary information in consideration of the driving situation without registering the preference information regarding the operation in advance. Accordingly, it is possible to reduce the operation burden and improve the information providing service level.

  In the vehicle information processing system according to the present invention, it is preferable that the traveling state acquisition unit acquires at least one of a traveling state of the vehicle and a traveling environment of the vehicle. According to this invention, the passenger can automatically obtain information in which at least one of the traveling state and the traveling environment is taken into account. Therefore, it is possible to further improve the service level for providing information.

  In the vehicle information processing system according to the present invention, the estimating means may estimate the information requested by the passenger using the operation status information acquired within a predetermined period by the operation status information acquiring means. preferable. According to the present invention, since the passenger automatically acquires necessary information and the period of the operation status information used by the estimation means is limited, more timely and useful information can be provided. Become.

  In the vehicle information processing system according to the present invention, the operation status information acquisition unit acquires the number of times of operation of the device in the passenger's vehicle, and the estimation unit corresponds to the number of operations acquired by the operation status information acquisition unit. Thus, it is preferable to estimate information requested by the passenger. According to this invention, since the estimation means estimates the information requested according to the number of operations of the passenger, it is possible to distribute more useful information for the passenger and improve the service level. Become.

  Further, in the vehicle information processing system according to the present invention, the estimating means sets a priority to the information related to the operation according to the number of operations, and the information providing means outputs the information set with a high priority by the estimating means. It is preferable to provide information preferentially. According to this invention, since the information providing means provides information according to the priority, it is possible to preferentially provide useful information to the passenger and improve the service level.

  The vehicle information processing system according to the present invention further includes display means for displaying information provided by the information providing means. The display means has a user interface displayed on the screen and is set as the estimation means. It is preferable to change the display mode of information in the user interface according to the priority. According to this invention, it becomes possible for a passenger to visually recognize necessary information, and the information providing service level can be improved because the information is displayed in a different manner depending on the priority.

  In the vehicle information processing system according to the present invention, it is preferable that the vehicle information processing system further includes an audio output unit that outputs information provided by the information providing unit by voice. According to the present invention, since the passenger can recognize the distributed information even by voice, the passenger can obtain necessary information in real time as well as improving the service level of information provision. It becomes possible. Therefore, it is possible to reduce distraction for the driving operation of the passenger's vehicle.

  In the vehicle information processing system according to the present invention, it is preferable that the information providing unit includes a timing setting unit capable of setting a timing at which the information providing unit provides the information. According to this invention, since the timing of information provision can be adjusted by the timing setting means, it becomes possible to acquire information at the timing required by the passenger, and the service level can be further improved.

  Next, an example of the operation of the vehicle information processing system 1 according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing a service manual distribution process of the vehicle information processing system 1. Each process in FIG. 2 is executed at regular intervals by the server 10 and the ECU 20.

  First, in step S20 (hereinafter referred to as “S20”, the same applies to other steps), the ECU 20 determines whether or not the operation of the same device in the vehicle 2 has been performed a plurality of times within a predetermined time. . Specifically, the transmission timing control unit 24 monitors the data in the operation history information database 22 and determines whether two or more pieces of data of the same device have been written within a predetermined time. If it is determined in S20 that the operation is not performed a plurality of times, the process returns to S20, and the process of S20 is repeated until the operation is performed a plurality of times. On the other hand, if it is determined in S20 that the operation has been performed a plurality of times, the process proceeds to S22.

  In S22, the ECU 20 performs transmission processing of vehicle information stored in the operation history information database 22 and the vehicle information database 23 and operation history information within a predetermined period. In S <b> 22, the vehicle information and the operation history information are transmitted to the server 10 by the ECU 20 via the communication unit 25 and the communication unit 14 and stored in the request estimation information database 13. The transmission process of S22 is performed at a timing preset by the transmission timing control unit 24, and is performed, for example, when the passenger presses the help button.

  And it transfers to S24 and the request | requirement estimation request process with respect to the request | requirement estimation part 11 is performed by ECU20. In S24, the ECU 20 requests the request estimation unit 11 to estimate which service manual is requested by the passenger of the vehicle 2, and the process proceeds to S26.

  In S26, keyword extraction processing by the request estimation unit 11 is executed. Specifically, keywords for service manual search are extracted from the vehicle information and operation history information stored in the request estimation information database 13. In S <b> 28, the request estimation unit 11 estimates a plurality of service contents required by the passenger and sets a priority for each estimated service. Thereafter, in S30, the request estimation unit 11 determines a service manual to be distributed to the passengers of the vehicle 2.

  After the request estimation unit 11 determines the service manual, the process proceeds to S32, and the request estimation unit 11 performs distribution processing of the determined service manual. At this time, the request estimation unit 11 distributes the service manual to the ECU 20 of the vehicle 2 via the communication unit 14 and the communication unit 25 in order of the set priority.

  Thereafter, in S34, a manual display process is performed by the manual display unit 21. In the manual display process, the passenger is notified through the screen that the service manual has been distributed, and the manual display unit 21 displays a plurality of manuals distributed from the server 10 on the screen in descending order of priority. Then, a series of processing ends. The passenger of the vehicle 2 can browse the contents of the service manual by selecting necessary ones from the displayed service manual. At this time, voice guidance of the service manual by the manual voice output unit 26 may be started.
