  Next, the details of the safety mechanism for controlling engine start by the mobile terminal of the present invention will be described. 2 is a perspective view of the front part of the control unit, FIG. 3 is a schematic explanatory diagram of a communication network showing cooperation between the mobile terminal and the engine, FIG. 4 is a block diagram of engine start control including a safety mechanism, and FIG. 5 is an engine start site. FIG. 6 is a plan view of the display showing the operation screen at the engine start site.

  As is well known in FIG. 2, the engine E of the tractor 10 (vehicle) is inserted into a key switch K provided at the front part of the control part O, for example, at the rear part of the dashboard 18 located on the side of the steering column cover 20. The engine E can be started and stopped by rotating a key (not shown) to a predetermined position.

  As shown in FIG. 3, the engine E of the tractor 10 of the present application is a mobile terminal M (in the illustrated example, a straight type mobile phone is shown, but is limited to a mobile phone such as a folding type or a sliding type or a plate-like smartphone). To the engine E via the network N (access means) and the information distribution server S that constitute the information providing means I to the engine E.

  The information distribution server S stores unique information of the mobile terminal M, the tractor 10 and the engine E, and can be installed at the worker's home, an agricultural cooperative, a data management company, a vehicle dealer, or the like. it can. The network N performs information transmission among the mobile terminal M, the information distribution server S, and the engine E.

  Further, as shown in FIG. 4, the engine E is subjected to various controls such as starting and stopping by a controller C installed in the vehicle. The controller C includes a network N of the information providing means I described above. The mobile terminal M is connected via Further, an engine start control mechanism CT as a safety mechanism is provided in the controller C, and information providing means I and an engine E are connected to the engine start control mechanism CT.

  The start of the engine E is a well-known technique described in, for example, Japanese Patent Application No. 2009-161656, and detailed description thereof will be omitted. However, as described above, the operator operates the key switch K as described above. When the start switch (not shown) is turned on, the controller C energizes the starter relay and energizes the starter relay while energizing the glow relay and solenoid relay constituting the engine start circuit for a predetermined time. By supplying current to the solenoid, the starting motor is activated and the engine E is started.

  Here, a method in which the worker starts the engine E of the tractor 10 using the safety mechanism of the present application will be described. First, as shown in FIG. 1 described above, the operator operates the mobile terminal M owned by the operator before operating the key switch K by, for example, sitting on the driver's seat 27, as shown in FIG. The engine start site ST is called on the display D.

  Next, as shown in FIG. 6A, a predetermined personal identification number A as an access means set in advance is inputted and transmitted to the engine start site ST. At this time, information (password A) transmitted from the mobile terminal M is transmitted to the information distribution server S via the network N.

  Next, in the information distribution server S, if the pre-registered unique information (such as a serial number) of the tractor 10 or the engine E matches the unique information (password A) of the mobile terminal M, via the network N, This is transmitted to the controller C of the engine E, and the controller C releases the engine start stop state in the engine start control mechanism CT (safety mechanism), and the mobile terminal M receives a notification as shown in FIG. Display above.

  If the unique information of the engine E and the unique information of the mobile terminal M do not match, the information distribution server S transmits to the mobile terminal M and the controller C, and the controller C starts the engine of the engine start control mechanism CT. While maintaining the restrained state, the mobile terminal M displays on the display D that the safety mechanism cannot be released.

  Thereby, the operator can start the engine E by operating the starting motor by the controller C as described above by operating the key switch K using the key of the vehicle.

  With such a configuration, when the engine E of the vehicle is started, the engine start control mechanism CT ( If the engine start stop state of the safety mechanism is not released, the engine E cannot be started, and accidents caused by mischief of children and theft can be prevented, and safety can be improved.

  In addition, the mobile terminal M is provided with a site accessible to the vehicle controller C, and by inputting and transmitting a preset recitation number as an access means, it is difficult to specify personal information from others. In addition to ensuring safety, the safety mechanism of the controller C can be easily and safely released by a simple operation such as inputting a password.

  Even if the operator attempts to start the engine E by operating the key switch K as usual without using the above-described safety mechanism by the mobile terminal M, the controller C does not have information on only the key switch K operation. Since the starting motor is not operated, the engine E cannot be started.

  However, as described above, the controller C starts the engine E when the controller C receives from the information from the mobile terminal M the release signal of the start stop state of the engine E and the signal from the key switch K operation. It is said.

  Further, the engine start control mechanism CT (safety mechanism) is not limited to the installation in the controller C as described above. For example, the engine start control mechanism CT (safety mechanism) is provided between the starter relay constituting the engine start circuit in the engine E and the starter solenoid. You may comprise by the switch etc. which were not shown in FIG.

  In this case, even if the key switch K is operated, current cannot be supplied to the starter solenoid by the switch, and the switch is turned on by the release information of the engine start control mechanism CT by the mobile terminal M, and the starting motor And the engine E can be started, and the same effect as described above can be obtained.

  The safety mechanism (engine start control mechanism CT) can be configured as follows. FIG. 7 is a block diagram of engine start control provided with a safety mechanism by reading information of a mobile terminal with a charger.

  In this case, the steering column cover 20 or the like, for example, although not shown, is a pocket that is closed on both sides and the bottom and is opened at the back (upper side of the driver's seat 27) upper part (not limited) of the steering column cover 20 An accommodating portion that can accommodate the mobile terminal M is provided.

  The housing portion is preferably slightly larger than the outer shape of the mobile terminal M, and the depth is preferably such that the mobile terminal M can be gripped with a finger. In addition, the main body of the accommodating part demonstrated below can use the same material as the steering column cover 20.

  Further, the housing portion can be formed integrally with the steering column cover 20 or can be detachably installed by bolt fastening or the like via a flange or the like (not shown).

  Then, the mobile terminal M is inserted into the accommodating portion (for example, as it is if it is a straight-type mobile phone or a plate-like smartphone, or folded if it is a foldable mobile phone). In addition, although the mobile terminal M may be inserted in the horizontal direction with respect to the accommodating part, it can also be inserted in the vertical direction. Further, when the mobile terminal M is taken out from the accommodating portion, the mobile terminal M can be easily taken out by grasping it with a finger.

  In addition, although not shown in figure, when the mobile terminal M is taken in and out, the opening part is expanded and the mobile terminal M is easily inserted or taken out by making the right and left both sides of the accommodating part into an elastic structure by an elastic member. You can also.

As will be described later, a charging connector 43 is provided.

  As shown in FIG. 7, the charging connector includes a wiring that connects the rechargeable battery 44 of the mobile terminal M and the on-vehicle battery B, and a wiring that connects the information output unit 45 and the controller C. That is, by connecting the charging connector 43 to the mobile terminal M, the mobile terminal M can be charged, and the unique information (ID number, etc.) of the mobile terminal M is transferred to the controller C (engine start control mechanism CT) via wiring. It is configured to transmit.

  Here, when the operator starts the engine E of the tractor 10, first, the charging connector 43 is connected to the mobile terminal M, and the mobile terminal M is accommodated in the accommodating portion, so that the mobile terminal M Specific information such as the above-described ID number of the mobile terminal M is transmitted from the information output unit 45 to the controller C via the wiring of the charging connector 43.

  Thereby, the controller C cancels the start stop state of the engine start control mechanism CT based on the specific information of the mobile terminal M if the predetermined specific information is preset. In addition, if it is the specific information of the other mobile terminal M which is not set, the start stop state of the engine start control mechanism CT is maintained.

  In the same manner as described above, the operator can start the engine E by operating the starting motor by the controller C as described above by operating the key switch K using the key of the vehicle.

  With such a configuration, for example, even in an area where the radio wave condition is poor, such as in a mountainous area, an operator can connect the mobile terminal M to the charging connector 43 (charger) provided in the vehicle via the charging connector 43. Thus, the controller C can easily and surely read predetermined information of the mobile terminal M, release the engine start control mechanism CT and start the engine E, and the same effect as described above can be obtained. Can also charge the mobile terminal M.

  Furthermore, the safety mechanism (engine start control mechanism CT) can be configured as follows. FIG. 8 is a perspective view of the front part of the steering unit where the mobile terminal is placed on the information reading unit provided in the steering unit such as a steering column cover, and FIG. 9 shows a safety mechanism by reading information of the mobile terminal with a non-contact type IC card. It is a block diagram of the engine starting control with which it is provided.

  In this case, the steering column cover 20 or the like is provided with an information reading unit 46 as an access means on the upper surface (not limited) of the steering column cover 20 as shown in FIG. The information reading unit 46 is a known unit that can read information of a non-contact type IC card built in the mobile terminal M, and is connected to the controller C.

  Further, as shown in FIG. 9, the mobile terminal M is provided with an information output unit 47 such as a well-known non-contact type IC card storing unique information (such as an ID number).

  Here, when the operator starts the engine E of the tractor 10, first, the surface having the information output unit 47 of the mobile terminal M is brought close to the information reading unit 46 on the upper surface of the steering column cover 20, Specific information such as the above-described ID number of the mobile terminal M is transmitted from the information output unit 47 of the mobile terminal M to the controller C via the information reading unit 46.

  Thereby, the controller C cancels the start stop state of the engine start control mechanism CT based on the specific information of the mobile terminal M if the predetermined specific information is preset. In addition, if it is the specific information of the other mobile terminal M which is not set, the start stop state of the engine start control mechanism CT is maintained.

  In the same manner as described above, the operator can start the engine E by operating the starting motor by the controller C as described above by operating the key switch K using the key of the vehicle.

  With such a configuration, as described above, even in an area where the radio wave condition is poor, such as a mountainous area, the operator can easily operate the mobile terminal M owned by the information reading unit 46 of the tractor 10 with an easy operation. The controller C can read predetermined information of the mobile terminal M via the information reading unit 46, and can easily and reliably release the engine start control mechanism CT, and can release the engine start control mechanism CT and start the engine E. The same effect as described above can be obtained.
