If the courtesy lamp 103 is off, the courtesy lamp 103 is turned on (ST13), and the process ends. If the courtesy lamp 103 is on, the process ends.

  If the sub door 60 is closed in ST11, the sub ECU 72 determines whether the sub door 60 has been opened based on the detection signal from the sub door open switch 63 (ST14).

  When the sub door open switch 63 is operated, the sub ECU 72 determines whether the child switch 83 is turned off based on the detection signal from the child switch 83 (ST15).

When the child switch 83 is off, the sub ECU 72 determines whether the tailgate 40 is closed based on the detection signal from the tailgate switch 81 (ST16). When the tailgate 40 is closed, the vehicle speed sensor 86, a vehicle speed v is measured (ST17), the sub ECU72 the vehicle speed v is determined whether slower than the reference speed _{v b} (ST18).

If the vehicle speed v is slower than the reference speed v _b is sub ECU72 determines based or rear wiper apparatus 90 is stopped on the detection signal from the rear wiper switch 94 (ST19). When the rear wiper device 90 is stopped, the sub ECU 72 controls the sub door latch device 61 to be in an unlatched state (ST20).

  As a result, the sub door latch device 61 is unlocked from the sub door striker 51 and the sub door 60 is opened. The sub ECU 72 turns on the courtesy lamp 103 (ST21), and ends.

  That is, the sub door open switch 63 is operated, the child switch 83 is turned off, the tailgate 40 is closed, the vehicle speed is slower than a predetermined speed, and the rear wiper device 90 is stopped. In this case, the opening of the sub door 60 is permitted.

If child switch 83 is turned on in ST15, if the tailgate 40 is open at ST16, or if the vehicle speed v than the reference speed _{v b} in ST18, the sub ECU72 is open the sub-door 60 Is prohibited and the process ends. In these cases, the sub door 60 is not opened.

  When the rear wiper device 90 is not stopped in ST19, that is, when the rear wiper device 90 is operating, the main ECU 71 transmits to the sub ECU 72 to move the blade 93 of the rear wiper device 90 to the stop position. To do. The sub ECU 72 controls the rear wiper device 90 (ST22).

  When the blade 93 of the rear wiper device 90 moves to the stop position, the sub ECU 72 stops the rear wiper device 90 (ST23) and ends. Whether the blade 93 is positioned at the stop position is determined by a detection signal from the rear wiper position sensor 85.

  When ST23 is completed, all of ST11 to ST18 are satisfied. By operating the sub door open switch 63 after the rear wiper device 90 is stopped, the sub ECU 72 controls the sub door latch device 61 to release the latch of the sub door 60 (ST20). In this case, the rear wiper device 90 can be stopped and the sub door 60 can be opened without turning the rear wiper device 90 off.

  Reference is also made to FIGS. The conditions for operating the rear wiper device 90 in relation to the sub door 60 will be described. First, based on the detection signal from the sub door switch 82, the sub ECU 72 determines whether the sub door 60 is in a closed state (ST31).

If the sub-door 60 is in the closed state, the vehicle speed v is measured by the vehicle speed sensor 86 (ST32), the sub ECU72 the vehicle speed v is the reference speed _v is determined whether faster than ₀ (ST33). If faster than the reference speed _{v 0,} the sub ECU72 determines whether the rear wiper apparatus 90 is stopped (ST34).

  When the rear wiper device 90 is stopped, the sub ECU 72 controls the rear wiper device 90 to operate (ST35), and ends. If the rear wiper device 90 is in operation, the process ends as it is.

  When the sub door 60 is closed and the vehicle speed is higher than a predetermined speed, the rear wiper device 90 can be operated (restarted).

  If the sub door 60 is open in ST31, the sub ECU 72 determines whether the rear wiper device 90 is stopped (ST36). If the rear wiper device 90 is stopped, the process is terminated. If the rear wiper device 90 is operating, the rear wiper device 90 is stopped and the process ends (ST37).

By ST33, the vehicle speed v is the same when the reference speed _{v 0} or less. That is, when the vehicle speed v is the reference speed _{v 0} or less at ST33, the sub ECU72 determines whether the rear wiper apparatus 90 is stopped (ST36). If the rear wiper device 90 is stopped, the process is terminated. If the rear wiper device 90 is operating, the rear wiper device 90 is stopped and the process ends (ST37).

  When the sub door 60 is open, the sub ECU 72 prohibits the operation of the rear wiper device 90. For this reason, the wiper device 90 can be operated only when the tailgate side window panel 48 and the subdoor side window panel 68 are flush with each other. It is possible to prevent the wiper device 90 from operating when there is a step between the window panels 48 and 68 and protect the wiper device 90.

  Please refer to FIG. 3, FIG. 5 and FIG. A case where the sub door 60 is opened in relation to the rear wiper device 90 will be described. Based on the detection signal from sub door switch 82, sub ECU 72 determines whether sub door 60 is closed (ST41).

  If sub door 60 is open, sub ECU 72 determines whether courtesy lamp 103 is extinguished (ST42). If the courtesy lamp 103 is off, the sub-ECU 72 turns on the courtesy lamp 103 (ST43) and ends. If the courtesy lamp 103 is lit, the process ends.

  If the sub door 60 is closed in ST41, the sub ECU 72 determines whether the sub door 60 has been opened based on the detection signal from the sub door open switch 63 (ST44).

  When sub door open switch 63 is operated, sub ECU 72 determines whether or not child switch 83 is turned off based on a detection signal from child switch 83 (ST45).

When the child switch 83 is off, the sub ECU 72 determines whether the tailgate 40 is closed based on the detection signal from the tailgate switch 81 (ST46). When the tailgate 40 is closed, sub ECU72 is the vehicle speed v is measured by the vehicle speed sensor 86 (ST47), the vehicle speed v is determined whether slower than the reference speed _{v b} (ST48).

If the vehicle speed v is slower than the reference speed _{v b} is sub ECU72 determines whether the rear wiper apparatus 90 is stopped (ST 49). When the rear wiper device 90 is stopped, the sub ECU 72 controls to release the sub door latch device 61 (ST50).

  As a result, the sub door latch device 61 is unlocked from the sub door striker 51 and the sub door 60 is opened. The sub ECU 72 turns on the courtesy lamp 103 (ST51), and ends.

  That is, the sub door open switch 63 is operated, the child switch 83 is turned off, the tailgate 40 is closed, the vehicle speed is slower than a predetermined speed, and the rear wiper device 90 is stopped. In this case, the opening of the sub door 60 is permitted.

If child switch 83 is turned on in ST45, if the tailgate 40 is open at ST46, or in the case of more than the vehicle speed v is the reference speed _{v b} in ST48, the process directly ends. That is, in these cases, the sub ECU 72 prohibits the opening of the sub door 60.

  When the rear wiper device 90 is operating in ST49, the rear wiper device 90 is controlled as described in FIG. 11 (ST52).

  Please refer to FIG. 3, FIG. 6 and FIG. The control of the rear wiper will be described. When the rear wiper device 90 is operating in ST49 of FIG. 10, the sub ECU 72 controls the rear wiper device 90 to move the blade 93 of the rear wiper device 90 to the stop position (ST61).

  When the blade 93 of the rear wiper device 90 moves to the stop position, the sub ECU 72 stops the rear wiper device 90 (ST62). Whether the blade 93 is positioned at the stop position is determined by a detection signal from the rear wiper position sensor 85.

  When the rear wiper device 90 stops, the sub ECU 72 turns on the buzzer 104 (ST63), and unlocks the sub door 60 (releases the latched state) (ST64). Thereby, the sub door 60 is opened. When sub door 60 is opened, sub ECU 72 turns on courtesy lamp 103 (ST65). That is, the courtesy lamp 103 is turned on.

When sub door 60 is closed again (ST66), sub ECU 72 turns off courtesy lamp 103 (ST67). Then, the vehicle speed v is measured by the vehicle speed sensor 86 (ST 68), the sub ECU72 the vehicle speed v is the reference speed _v is determined whether faster than ₀ (ST69). If faster than the reference speed _{v 0,} the sub ECU72 controls the rear wiper device 90 to actuate the rear wiper device 90 (ST70), and ends.

If the reference speed v ₀ or less is measured again the vehicle speed v. That is, after the sub door 60 is opened, the sub door 60 is closed, and when the vehicle 10 travels again, the rear wiper device 90 operates again. At this time, there is no need to operate the rear wiper device 90. Furthermore, the vehicle 10 travels again, to greater than the reference speed v _0, the rear wiper device 90 is maintained in a stopped state.

  If the rear wiper switch 94 of the rear wiper device 90 is turned off before the vehicle 10 starts to travel again, the rear wiper device 90 does not operate. In this case, the sub ECU 72 moves the blade 93 to the stop position after the vehicle 10 travels, and stops the rear wiper device 90.

  The present invention described above has the following effects.

  Please refer to FIG. The vehicle information can be transmitted to and received from the main ECU 71, and the tailgate 40 and the sub ECU 72 that controls the sub door 60 are included. The sub ECU 72 controls the two doors of the tail gate 40 and the sub door 60. Since there are few doors to be controlled and few functions are required, an inexpensive ECU can be adopted as the sub ECU 72. Compared to the case of newly developing a main ECU with many doors to be controlled, the cost of components can be reduced. Even if the subgate 60 is provided in the tailgate 40, the vehicle 10 which can be controlled by cheap parts can be provided.

  Please refer to FIG. When the sub-ECU 72 detects an operation signal of the tailgate open switch 43, the sub-ECU 72 determines an opening permission condition for the tailgate latch device 31 based on the vehicle information received from the main ECU 71. Alternatively, when the sub ECU 72 detects an operation signal of the sub door open switch 63, the sub ECU 72 determines an opening permission condition for the sub door latch device 61 based on the vehicle information received from the main ECU 71. In the sub ECU 72, the opening condition of the tail gate latch device 31 or the sub door latch device 61 is determined. Therefore, the main ECU 71 does not need to determine which of the latch devices of the tailgate 40 and the sub door 60 should be driven, and only needs to recognize the sub ECU 72 as one door device. There is no need to make a major change from the conventional ECU to the main ECU 71. For this reason, an increase in component cost can be suppressed.

  Please refer to FIG. The opening permission condition of the tailgate latch device 31 includes that the sub door 60 is not opened. That is, the sub ECU 72 controls the tailgate latch device 31 to prohibit the opening of the tailgate 40 when it is determined that the subdoor 60 is open. In addition, the opening permission condition of the sub door latch device 61 includes that the tailgate 40 is not opened. That is, the sub ECU 72 controls the sub door latch device 61 to prohibit the opening of the sub door 60 when it is determined that the tailgate 40 is open. Thereby, when one of the tailgate 40 or the sub door 60 is open, it is possible to prevent the other door from being opened at the same time. It can be said that the vehicle can accurately operate the door.

  Further, the rear wiper device 90 provided on the tail gate 40 or the sub door 60 is controlled by the sub ECU 72 in accordance with the locking state of the tail gate latch device 31 or the locking state of the sub door latch device 61. . For example, when the sub door 60 is opened, the sub door latch device 61 is in an unlatched state. By prohibiting the operation of the rear wiper device 90 when the sub door 60 is in the unlatched state, the rear wiper device 90 can be prevented from contacting the sub door 60 and the rear wiper device 90 can be protected. As another example, when the rear wiper device 90 is operated, the sub door latch device 61 is controlled to prohibit the opening of the sub door 60. Contact of the rear wiper device 90 to the sub door 60 can be prevented, and the rear wiper device 90 can be protected. The open state of the tailgate 40 or the sub door 60 is managed on the sub ECU 72 side and cannot be grasped on the main ECU 71 side, but by controlling the rear wiper device 90 on the sub ECU 72 side, the tail gate 40 or Control according to the open state of the subdoor 60 can be performed.

  Further, the sub ECU 72 sends a detection signal from the tailgate / subdoor lock switch 67 to the main ECU 71, and locks / unlocks both the tailgate 40 and the subdoor 60 in response to a response from the main ECU 71. When the vehicle 10 is used, when either the tailgate 40 or the sub door 60 is opened, there is little need to keep the other locked. By exchanging single lock / unlock data with the main ECU 71 in the sub ECU 72, it is not necessary to largely change the control on the main ECU 71 side, and an increase in cost can be suppressed.

  Further, the tailgate / subdoor lock switch 67 is provided only on one of the tailgate 40 and the subdoor 60. An increase in the number of components can be suppressed, and an increase in component costs can be suppressed.

  Please refer to FIG. The sub ECU 72 is provided at a corner portion P1 between the right edge 30b (one side edge 30b) and the lower edge 30d of the tailgate opening 30. The corner portion P1 formed by the right edge 30b and the lower edge 30d of the tailgate opening 30 has high strength. Since the sub ECU 72 is arranged on the pillar 19a (vehicle body side), not on the side of the tail gate 40 and the sub door 60 that are opened and closed, it is possible to reduce the influence of the load applied to the sub ECU 72 due to the opening and closing of the doors 40 and 60.

  Further, the sub door 60 is opened from the other side edge 30 c of the tailgate opening 30. In addition, a sub door latch harness 75 extending from the sub ECU 72 to the sub door latch device 61 extends upward from the corner portion P1 and passes through the tail gate 40 from the top of the tail gate 40. Since the entrance of the subdoor latching harness 75 to the tailgate 40 is disposed on the side opposite to the opening side of the subdoor 60, the length of the subdoor latching harness 75 from the tailgate 40 to the subdoor can be shortened.

  Furthermore, the ECU harness 73 extends in the front-rear direction at the end of the vehicle body on the right edge 30b (one side edge 30b) side. While reducing the sum total of the length of each harness 73-75 which connects from main ECU71 to the subdoor latch apparatus 61, each harness 73-75 can be passed through a high intensity | strength site | part.

  In addition, a sub ECU 72 is disposed at an end (end on the driver's seat side) opposite to the opening end (end on the passenger seat side) of the sub door 60. The influence of the load applied to the vehicle body 19 when the sub door 60 is opened and closed can be suppressed from being transmitted to the sub ECU 72.

  In the embodiments, a right-hand drive wagon car has been described as an example. However, the present invention can be applied to vehicles other than a left-hand drive wagon car and a wagon car such as a bus. In other words, the embodiments are merely examples of the present invention, and the present invention is not limited to these types as long as the operations and effects are achieved.

  The vehicle of the present invention is suitable for a wagon car.
