  However, the in-vehicle device or system disclosed in Patent Document 1 is requested without considering the positional relationship of a plurality of vehicle members driven by remote operation when a remote operation is requested or when a requested operation is performed. There is a problem in that you can execute the operation.

  If an object that can move or move the body of a person or animal is present in the vehicle interior or the vicinity of the vehicle and the requested operation is an operation to physically move the vehicle member, this person or animal This is because there is a possibility that the movement of the vehicle and the movement of the vehicle member may cause interference.

  In particular, when an operation requested by a remote operation physically moves a vehicle member to form a gradually narrowing gap, or when a part of a human or animal body is sandwiched in the formed gap There is.

  Here, the operation of physically driving the vehicle member is, for example, a drive operation of a power window, a power slide roof, a power slide door, a power back door, an electric trunk, an electric door mirror, or an electric sunshade, and gradually decreases. Formation of a gap means that a driven window glass, slide roof glass, slide door, sunshade seat, door mirror, etc. are close to each other and form a gap that sandwiches a part of a human or animal body. Say.

  Thus, in the conventional apparatus, when a person or an animal exists in the vehicle interior or the vicinity of the vehicle, an inappropriate remote operation may be executed.

  The present invention has been made to solve such problems, and it is a main object of the present invention to provide an in-vehicle device that prevents inappropriate movement of the electric device by remote control.

  One aspect of the present invention for achieving the above-described object is an in-vehicle apparatus that includes a communication unit that receives a remote operation request, and that executes a predetermined operation in response to the remote operation request received by the communication unit. And an electric device control means for controlling an electric device that physically moves a member of the vehicle, and a member position detection means for detecting the position of the member that is moved by the electric device, wherein the electric device control means includes the member position The first electric device and the other electric device so that the position of the member moved by one electric device detected by the detecting means and the position of the member moved by the other electric device are not in a predetermined positional relationship. It is an in-vehicle device characterized by controlling at least one of these.

  In this one aspect, the first electric device is a power window that electrically drives a window glass, and the other electric device is an electric sunshade that is in the vicinity of the power window and moves the sunshade seat electrically. The electric device control means does not form a predetermined gap between the position of the sunshade seat moved by the electric sunshade and the position of the window glass moved by the power window, which are detected by the member position detecting means. The sunshade sheet is moved to a predetermined position.

  Further, in this one aspect, when the member position detection unit detects that the sunshade sheet is not moved to the predetermined position, or when it cannot detect that the sunshade sheet is in the predetermined position, The electric device control means prohibits driving of the power window.

  With the above-described means, the present invention can provide an in-vehicle device that prevents inappropriate movement of the electric device by remote control.

  Hereinafter, the best mode for carrying out the present invention will be described in several embodiments with reference to the drawings.

  FIG. 1 illustrates a vehicle remote control system 100 according to an embodiment of the present invention and an in-vehicle device 104 used in the system.

  A vehicle remote control system 100 according to this embodiment includes a vehicle 101 that is a target of remote control, and a communication station that is managed and operated by, for example, a vehicle manufacturer (manufacturer), a car retailer (dealer), or a specialist. 102 and a communication terminal 103 carried by a vehicle user (owner).

  The center 102 receives an operation command transmitted by the vehicle user using the communication terminal 103, and transmits the operation command to the in-vehicle device 104 of the vehicle 101.

  The communication terminal 103 is, for example, a mobile phone that can be connected to the Internet. Alternatively, as an alternative, a computer terminal such as a PDA (Personal Digital Assistance) or a notebook PC (Personal Computer) having a communication function may be used.

  The in-vehicle device 104 controls the electric device according to the operation command received from the center 102.

  FIG. 2 is a schematic configuration diagram of the in-vehicle device 104 used in the vehicle remote control system 100 according to an embodiment of the present invention.

  The in-vehicle device 104 includes a communication unit 201, an electric device control unit 202, and a member position detection unit 203, and is connected to the communication unit 105, the ignition switch 106, the power window 107, and the electric sunshade 108.

  The communication unit 105 is a communication device including a vehicle-mounted antenna or the like, and receives an operation command transmitted from the communication terminal 103 via the center 102. In addition, information about the vehicle 101 detected by the in-vehicle device 104 or the like is transmitted to the center 102.

  The ignition switch 106 is a switch for switching on / off the ignition, and transmits the ignition state to the in-vehicle device 104.

  The power window 107 is an electric device that electrically opens and closes the window glass 302 (see FIG. 3). The power window 107 includes a sensor that detects that an object has interfered with the opening / closing operation of the window glass 302. When the interference is detected when the window glass 302 is closed, the power window 107 causes the window glass 302 to rise. Cancel or lower the window glass 302 to open the window glass 302.

  Further, the power window 107 transmits information indicating whether or not the window glass 302 is closed to the in-vehicle device 104.

  The electric sunshade 108 is an electric device that electrically drives a sunshade seat 303 for blocking sunlight from the side window glass 302 of the rear seat (see FIG. 3). Here, FIG. 3 is a diagram showing a positional relationship between the window glass 302 and the sunshade sheet 303. The sunshade sheet 303 for the side window glass 302 is stored in the door trim 305 of the rear door 301 when not in use, and is driven upward from the inside of the door trim 305 by a drive motor when in use so as to cover the entire side window glass 302. To do. The sunshade sheet 303 normally rises to the vicinity of the ceiling in the passenger compartment, but the height may be adjusted steplessly to an arbitrary height up to the ceiling. Further, since the sunshade sheet 303 needs to maintain a substantially upright posture along the side window glass 302 when used, the upper end portion 304 and the left and right end portions thereof are made of a hard member such as reinforced plastic, and other portions. However, it is composed of light and soft members such as synthetic fibers for weight reduction and ease of storage. Note that the entire sunshade sheet 303 may be formed of a hard member.

  In addition, the electric sunshade 108 transmits information indicating whether or not the sunshade seat 303 is stored in the door trim 305 to the in-vehicle device 104.

  The communication unit 201 acquires the operation command received by the communication unit 105 from the center 102 and transmits the operation command to the electric device control unit 202.

  The electric device control means 202 opens and closes the window glass 302 by the power window 107 or stores the sunshade seat 303 in the door trim 305 by the electric sunshade 108 based on the operation command received by the communication means 201 from the communication unit 105. .

  The member position detecting means 203 detects whether or not the window glass 302 driven by the power window 107 is in an open state based on a signal from an electric device such as the power window 107 or is driven by the electric sunshade 108. It is detected whether or not the sunshade sheet 303 to be stored is stored in the door trim 305. Note that the member position detecting unit 203 may acquire more detailed member position information such as how much the window glass 302 and the sunshade sheet 303 are opened and closed. The member position detection unit 203 may transmit the state of the member to the communication terminal 103 of the vehicle user via the communication unit 201, the communication unit 105, and the center 102.

  The in-vehicle device 104 detects that the ignition is off based on a signal from the ignition switch 106 and detects that the sunshade seat 303 is not stored in the door trim 305 based on a signal from the electric sunshade 108. The electric sunshade 108 may be driven so that the sunshade seat 303 is stored in the door trim 305. This is to prevent a finger from being caught between the side window glass 302 and the sunshade sheet 303 as will be described below.

  As shown in FIG. 3, the sunshade sheet 303 for the side window glass 302 is preferably capable of thinning the door trim 305 to ensure as much space as possible in the vehicle interior, or can reliably block sunlight from the outside. The side window glass 302 is disposed in the vicinity. As a result, the side window glass 302 and the sunshade sheet 303 form a gap S between the upper end portion 304 of the sunshade sheet made of a hard member and the upper end portion of the side window glass 302 depending on the mutual positional relationship. For example, when the side window glass 302 is closed in a state where a person is placing a hand on the sunshade sheet upper end portion 304 (an arrow D in FIG. 3 indicates a direction in which the window glass 302 is closed), the person's hand enters the gap S. There is a case of getting injured.

  For example, according to the index of JM (Japane Male) 95, which covers 95% of the physique of a Japanese adult male, the thickness of a human finger is about 16 (average value) ± 2 (standard deviation) mm. Considering up to 3 standard deviations, it can be said that the fingers are hardly pinched if the gap S between the side window glass 302 and the sunshade sheet 303 is larger than 22 mm.

  Based on the above consideration, the vehicle-mounted device 104 detects the state of the window glass 302 and the sunshade sheet 303 by the member position detection unit 203, and when detecting that the sunshade sheet 303 is stored in the door trim 305, the power window 107 is driven to close the window glass 302 to prevent a finger or a part of the body from being caught in the gap S between the window glass 302 and the sunshade sheet 303.

  In addition, when the member position detection unit 203 detects that the sunshade seat 303 is not stored in the door trim 305, the in-vehicle device 104 first stores the sunshade seat 303 in the door trim 305 by the electric sunshade 108, and the sunshade seat 303 The window glass 302 may be closed by the power window 107 after the member position detecting means 203 detects that is stored in the door trim 305.

  The in-vehicle device 104 calculates in advance a gap S that can be formed between the window glass 302 and the sunshade sheet 303 when the window glass 302 is closed by the power window 107 from the positions of both members, and the calculated gap S is a predetermined value. The window glass 302 may be closed by the power window 107 if the width is larger than the width (for example, 22 mm in order to prevent pinching of fingers).

  Next, processing in which the in-vehicle device 104 controls the power window 107 will be described. FIG. 4 is a flowchart showing the flow of processing by the in-vehicle device 104.

  First, the in-vehicle device 104 determines whether or not the communication unit 201 has received an operation command for closing the window glass 302 from the communication terminal 103 (step S401).

  If the in-vehicle device 104 determines that the communication unit 201 has not received the operation command from the communication terminal 103 (NO in step S401), the in-vehicle device 104 waits until the communication unit 201 receives the operation command. When the in-vehicle device 104 determines that the communication unit 201 has received an operation command from the communication terminal 103 (YES in step S401), the member position detection unit 203 uses the information regarding the position of the sunshade seat 303 received from the electric sunshade 108. Based on this, it is detected whether or not the sunshade sheet 303 is stored in the door trim 305 (step S402).

  When the member position detection unit 203 detects that the sunshade seat 303 is stored in the door trim 305 (YES in step S402), the in-vehicle device 104 controls the power window 107 by the electric device control unit 202, and the window glass 302 is changed. Try to close.

  On the other hand, when the member position detection unit 203 detects that the sunshade sheet 303 is not stored in the door trim 305, or when the member position detection unit 203 cannot detect that the sunshade sheet 303 is stored in the door trim 305. (NO in Step S402), the in-vehicle device 104 ends the process without controlling the power window 107 by the electric device control means 202. Depending on the arrangement of the sunshade sheet 303, a finger may be caught in the gap between the window glass 302 and the sunshade sheet 303. Even if such a situation occurs, the power window 107 can be quickly driven for remote operation. This is because it cannot be stopped.

  Note that “when the member position detecting unit 203 cannot detect that the sunshade sheet 303 is stored in the door trim 305” means that the electric sunshade 108 or the member position detecting unit 203 fails and the position of the sunshade sheet 303 cannot be detected. This refers to cases.

  Next, another process in which the in-vehicle device 104 controls the power window 107 will be described. FIG. 5 is a flowchart showing the flow of another process performed by the in-vehicle device 104. Here, steps other than step S503 are the same as the processing in the flowchart shown in FIG.

  The in-vehicle device 104 causes the member position detection unit 203 to detect whether or not the sunshade sheet 303 is stored in the door trim 305 based on the information regarding the position of the sunshade sheet 303 received by the member position detection unit 203 from the electric sunshade 108 ( Step S502). Then, when the member position detection unit 203 detects that the sunshade sheet 303 is not stored in the door trim 305 or when the member position detection unit 203 cannot detect that the sunshade sheet 303 is stored in the door trim 305. (NO in step S502), the in-vehicle device 104 controls the electric sunshade 108 by the electric device control means 202, and stores the sunshade seat 303 in the door trim 305 (step S503).

  As a result, the in-vehicle device 104 eliminates the possibility of forming a gap S that may pinch a finger between the window glass 302 and the sunshade sheet 303, and then controls the power window 107 by the electric device control means 202. The glass 302 is closed (step S504).

  The in-vehicle device 104, in principle, drives the electric sunshade 108 by using the electric device control means 202 when the ignition switch 106 is turned off regardless of the presence or absence of an operation command by remote operation. 303 is stored in the door trim 305, but the sunshade seat 303 may be used even when the ignition switch 106 is turned off, such as blocking sunlight during parking, and the gap S is also formed in such a case. Can be reliably prevented.

  In this way, when the in-vehicle device 104 receives an operation command for closing the window glass 302 by remote operation, the in-vehicle device 104 detects the state of the window glass 302 and the sunshade sheet 303 and creates a gap that sandwiches a part of the body. Since the power window 107 and the electric sunshade 108 are controlled so as not to be formed, finger filling or the like can be reliably prevented.

  Further, even if the control device 104 or the electric sunshade 108 is out of order, the in-vehicle device 104 prohibits driving of the power window 107 unless detecting that the sunshade seat 303 is stored in the door trim 305. Thus, it is possible to reliably prevent a state in which a part of the body is sandwiched.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the gap S is prevented from being formed by the window glass 302 and the sunshade sheet 303, but the gap is prevented from being formed by the electric retractable door mirror and the window glass 302. It may be. In addition, the present invention is applied to prevent the two or more movable members from forming a gap that sandwiches a part of the body by remotely operating the electric device.
