Description

[Technical field]

[0001] The present invention relates to a device, a program, etc. that are retrofitted to a vehicle. [Background technology]

[0002] There are known vehicles that allow a door lock command to be given to the vehicle using a remote control, a smart key, etc. Also, there are known vehicles that have a door lock reservation function that automatically locks the door after the door is closed when the door is open (Patent Document 1). The door lock reservation function is particularly useful for doors that require a certain time to close, such as an electrically operated sliding door. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-185339 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a vehicle without a door lock reservation function, the doors are usually not locked even if a door lock command is given when any of the doors is open. Therefore, the user needs to confirm that all the doors are closed before giving a door lock command to the vehicle. For example, in the case of an electrically operated door, the user needs to wait until the door is closed before giving a door lock command, and when loading and unloading luggage or when people get on and off the vehicle, the door needs to be closed after these operations are completed, and then the door lock command needs to be given. Such waiting time until the door is closed or confirmation that the door is closed is inconvenient or troublesome for the user. In addition, the user may think that the door has been locked by operating the door lock command when the door is open, and may forget to give the door lock command after the door is closed, which is a problem in terms of crime prevention.

[0005] In vehicles with a door lock reservation function, the doors are automatically locked after they are closed, eliminating or reducing the above-mentioned inconvenience, hassle, security problems, etc. However, vehicles with the door lock reservation function are limited to certain models such as luxury cars, and users who own vehicles without the door lock reservation function cannot enjoy the benefits of the door lock reservation function, and therefore cannot eliminate the above-mentioned inconvenience, hassle, security problems, etc.

[0006] SUMMARY OF THE DISCLOSURE This application discloses inventions that address some or all of the above problems or other issues. [Means for solving the problem]

[0007] This application discloses, for example, the inventions described in the following configuration examples.

[0008] <Configuration example 1> The invention of configuration example 1 is a device that is retrofitted to a vehicle having a function of not locking the doors of a vehicle when a door lock command is issued to the vehicle with the door of the vehicle open, and locking the doors of the vehicle when a door lock command is issued to the vehicle with the door of the vehicle closed, When a door lock command is received, if any door of the vehicle is open, a door lock signal is output to the vehicle after all the doors of the vehicle are closed. The device is characterized by:

[0009] In the invention of configuration example 1, it is possible to output a door lock signal to the vehicle after all the doors are closed.

[0010] The "door lock command" may be, for example, a command based on detection of pressing a door lock button on a vehicle remote control, or a command based on detection of touching a touch portion of a smart key on the outside of the vehicle door.

[0011] The "door lock instruction" may be, for example, an instruction that the device receives from the vehicle when a door lock command is issued to the vehicle. In this way, the user only needs to give a door lock command to the vehicle and does not need to perform any additional operation on the device. It is preferable that the device does not receive a "door lock instruction" when a door lock command is issued to the vehicle with the vehicle doors closed, but receives a "door lock instruction" when a door lock command is issued to the vehicle with the vehicle doors open, in order to simplify processing.

[0012] The "door lock signal" may be a signal that causes the vehicle to lock the doors. In this way, if a door lock command is given to the vehicle, the door lock signal is output to the vehicle after all the doors are closed, and the vehicle locks the doors. This eliminates or reduces the inconvenience, complexity, and crime prevention problems of users who own vehicles that cannot give a door lock command until the doors are closed.

[0013] The vehicle has a lock control unit that controls the door locks and a body control unit that can communicate with the lock control unit, and the lock control unit is configured to lock the doors when it receives a door lock signal from either the body control unit or the device, thereby simplifying control.

[0014] The "door lock command", "door lock instruction", and "door lock signal" may be expressed as, for example, "signal", "information", etc.

[0015] The "retrofit" may be installed at the user's discretion after purchasing the vehicle. The ability to "retrofit" makes it possible to apply the device to vehicles in which a door lock command cannot be given until the doors are closed. If the device can be retrofitted inside the vehicle, particularly inside the passenger compartment, this is favorable since it enhances crime prevention, and if the device can be detachably retrofitted, this is even better since it will be possible to use the device even if the vehicle is replaced. As a "retrofit," it is particularly favorable to configure the device to be installed in a position accessible from inside the passenger compartment where it can be installed by the user.

[0016] The "vehicle door closed state" may be, for example, a state in which the vehicle door is completely closed. The completely closed state is not limited to a sealed state. For example, the window may be open or there may be a gap. It may be possible to detect whether the door is closed to an extent that does not pose a crime prevention problem, and determine that the door is completely closed if the door is closed to an extent that does not pose a crime prevention problem based on the detection result. The "state in which the vehicle doors are closed" may be a state in which the doors can be locked, and more preferably, a state in which the vehicle doors are determined to be closed.

[0017] The "vehicle door is open" may be, for example, a state in which the vehicle door is not completely closed. The state in which the vehicle door is not completely closed is not limited to a state in which the door is not sealed, and is not limited to an open state. The "vehicle door is open" may be a state in which the door cannot be locked, and may further be a state in which the vehicle door is determined to be not closed.

[0018] The vehicle may have an opening / closing detection means for detecting whether the doors are closed or not. The device may determine whether all the vehicle doors are closed or not based on the detection result of the opening / closing detection means. The device may be configured to include the vehicle door opening / closing detection means, but the device may be configured to directly or indirectly obtain the detection result of the vehicle opening / closing detection means.

[0019] The vehicle may have only one door, but is particularly preferably a vehicle with multiple doors. This is because a vehicle with multiple doors is more inconvenient and complicated for the user and has greater security problems due to the door lock command being unable to be given until the doors are closed. It is preferable to have a configuration in which the detection results of open / close detection means provided on each of the vehicle's multiple doors are directly or indirectly obtained.

[0020] <Configuration example 2> In the invention of configuration example 2, whether or not the door lock instruction has been received is determined based on a signal indicating that the door lock command has been received, the signal being obtained from the vehicle side; determining whether any door of the vehicle is open or all doors of the vehicle are closed based on the open / closed states of all doors acquired from the vehicle side; The door lock signal is a signal for the vehicle to lock the doors. The device is characterized by:

[0021] According to the invention of the second configuration example, the user only needs to give a door lock command regardless of whether the door is open or closed, and the device can determine whether the door lock command has been received and whether any of the vehicle doors are open or all of the vehicle doors are closed, and can lock the vehicle doors. If the signal for making these determinations is received at one location (e.g., an OBD connector), this is preferable because it simplifies the wiring and facilitates installation. If the door lock signal is also output to the vehicle from the same one location, this is even more preferable because it further simplifies the wiring and facilitates installation.

[0022] The vehicle may have an open / close detection means for detecting the open / close state of the door. The device may be configured to include the open / close detection means for the vehicle door, but the device may be configured to directly or indirectly obtain the detection result of the open / close detection means for the vehicle.

[0023] <Configuration example 3> The invention of the third configuration example is a vehicle in which, when the door is open, it takes a predetermined time for the door to be closed after a command to close the door is given, and the vehicle is equipped with a function to cancel a door lock command when a door lock command is given to the vehicle with the door open. The device is characterized by:

[0024] In the invention of the third configuration example, if the user only issues a door lock command while the door is open, the door will be locked when the door is closed. Therefore, it is no longer necessary to wait a predetermined time until the door is closed before issuing a door lock command. Therefore, it is no longer necessary to wait a predetermined time near the vehicle until the door is closed, and the user can immediately start leaving the vehicle.

[0025] The "vehicle that requires a certain amount of time to close the door" may be, for example, a vehicle that has an electric sliding door. The longer the "certain amount of time," the greater the effect. For example, if the door is an electric sliding door, it usually takes several to 10 seconds for the door to close, so the effect of the invention of configuration example 3 is great.

[0026] <Configuration Example 4> The invention of configuration example 4 is such that the vehicle in which the door takes a predetermined time to close is a vehicle having a function of moving the door by power to close it when a command to close the door is received. The device is characterized by:

[0027] In the invention of configuration example 4, the user only needs to instruct to close the door and give a door lock command, and the vehicle door is poweredly closed and locked.

[0028] For example, it is preferable to be able to give a command to close the doors to the vehicle by operating a button, etc. It is preferable to be able to give a command to close the doors and a command to lock the doors to the vehicle by operating a button, etc., because this simplifies the operation. For example, it is possible to automatically close and lock the vehicle doors by power with a single touch of a button.

[0029] The "vehicle whose door is closed by moving it by power" may be, for example, a vehicle having an electric sliding door.

[0030] <Configuration Example 5> In the invention of configuration example 5, the vehicle has a function of issuing an alarm when a door lock command is issued with any door open, The device has a function of receiving a door lock instruction from the vehicle side, and a function of outputting a signal to limit the alarm to the vehicle side when the door lock instruction is received from the vehicle side. The device is characterized by:

[0031] In the invention of configuration example 5, when the device is installed in a vehicle in which an alarm is issued when a door lock command is issued with the door open, the alarm from the vehicle can be restricted.

[0032] An "alarm" may be, for example, the output of an alarm sound, particularly a continuous alarm sound. Such alarms are very annoying to the user, so limiting the alarm is effective. An "alarm limit" may be, for example, the stopping or suppression of the alarm sound. An "alarm" may be, for example, the lighting of an alarm lamp.

[0033] <Configuration Example 6> The invention of the sixth configuration example outputs a door unlock signal as a signal to limit the alarm. The device is characterized by:

[0034] In the invention of configuration example 6, it is possible to limit the warning in a vehicle having a function for limiting the warning when a door unlock signal is received.

[0035] <Configuration Example 7> In the invention of configuration example 7, the vehicle is a first door lock function for issuing a door lock command for the vehicle to enter an alarm state when the vehicle doors are locked; a second door lock function for providing the door lock command to lock the doors of the vehicle but not enter an alarm state; Equipped with The door lock signal is a signal for executing the first door lock function. The device is characterized by:

[0036] In the invention of configuration example 7, the vehicle can be locked and put into an alert state.

[0037] The "alert state" may be a state in which it becomes difficult to unlock the doors, a state in which an alarm is issued when a specific event occurs, etc. By setting the vehicle in such an alarm state, the crime prevention of the vehicle can be improved.

[0038] The "first door lock function" may be executed based on, for example, a signal based on detection of pressing a door lock button on a remote control, or a signal based on detection of touching a touch part of a smart key on the outside of the vehicle door. These operations can be performed from outside the vehicle, but because they can put the vehicle into an alarm state, crime prevention can be maintained even if the user leaves the vehicle.

[0039] The "second door lock function" may be executed based on a signal generated by pressing a central door lock button inside the vehicle. Since the central door lock button inside the vehicle can only be pressed inside the vehicle, the security of the vehicle is maintained even if the vehicle is not put into an alarm state.

[0040] <Configuration Example 8> The invention of configuration example 8 is provided with a function of unlocking the doors when there is an input for unlocking the doors from a second door lock command input unit that inputs an instruction to execute the second door lock function when the vehicle is not in the alert state, and not unlocking the doors when there is an input for unlocking the doors from the second door lock command input unit when the vehicle is in the alert state. The device is characterized by:

[0041] In the invention of configuration example 8, when the vehicle is in an alert state, even if the second door lock command input unit is operated from outside the vehicle using a wire or the like, thereby inputting an input to unlock the doors, the doors of the vehicle will not be unlocked, which is useful for preventing theft of the vehicle or items inside the vehicle.

[0042] The "second door lock command input unit" may be, for example, a central door lock button in the vehicle. <Configuration Example 9> In the invention of configuration example 9, the vehicle is When the first door lock function is executed, a hazard lamp of the vehicle is flashed. When the second door lock function is executed, the hazard lamps of the vehicle are not flashed. Equipped with functions, The door lock signal is a signal for executing the first door lock function. The device is characterized by:

[0043] In this way, the hazard lamps can be made to flash when the door is locked by the device, so that the user can easily recognize that the door is locked even if the user is already leaving the vehicle when the device locks the door.

[0044] <Configuration Example 10> The invention of configuration example 10 is such that the door lock signal is a signal for executing the first door lock function after a signal for executing the second door lock function is output. The device is characterized by:

[0045] For example, depending on the vehicle model or the compatibility between the device and the vehicle, there is a possibility that the door may not be properly locked by only outputting a signal to execute the first door lock function. Also, the vehicle cannot be put into an alert state by only outputting a signal to execute the second door lock function. In the invention of configuration example 10, a signal to execute the first door lock function is output after outputting a signal to execute the second door lock function, so that the door can be locked more reliably and the vehicle can be put into an alert state. Therefore, this further contributes to the prevention of theft of the vehicle and items inside the vehicle.

[0046] The signal for executing the second door lock function is preferably a signal that can lock the doors more reliably than the signal for executing the first door lock function.

[0047] <Configuration Example 11> In the invention of configuration example 11, the vehicle has a function of unlocking the doors when the doors are locked when a remote control for outputting the door lock command by a user operation is inside the vehicle, After outputting the door lock signal to the vehicle side, the device outputs a signal to the vehicle side to check whether the remote control is inside the vehicle. The device is characterized by:

[0048] In a vehicle having a function to unlock the doors when the doors are locked while the remote control is inside the vehicle, the function is usually not activated because it is not considered that an in-lock state (a state in which the doors are locked while the remote control is left inside the vehicle) occurs when the doors are locked by operating the remote control. In the invention of configuration example 1, since there may be a time lag between the door lock command and the output of the door lock signal, an in-lock state may occur even if the door lock command is given to the vehicle by operating the remote control. For example, if a user gives a door lock command by operating the remote control, drops the remote control inside the vehicle, closes the door without noticing, and the door is locked by the door lock signal, the in-lock state occurs. In the invention of configuration example 11, after the device outputs the door lock signal and the doors are locked, if the remote control is inside the vehicle, the vehicle can be made to unlock the doors. Therefore, even if the in-lock state occurs in the above-mentioned situation, the door lock can be made to unlock.

[0049] <Configuration Example 12> The invention of configuration example 12 includes a control means for realizing the above-mentioned functions, a connection means for connecting to a vehicle side in order to obtain the door lock command and the open / closed state of the door from the vehicle side and output the door lock signal to the vehicle side; The connecting means is a connector that can be attached to and detached from a connector provided on the vehicle side. The device is characterized by:

[0050] In the invention of configuration example 12, the function of configuration example 1 can be realized simply by attaching it to a connector on the vehicle side. The "connector" may be, for example, an OBD connector.

[0051] <Configuration Example 13> In the invention of the configuration example 13, the control means is housed in a housing having the connector. The device is characterized by:

[0052] The invention of configuration example 13 has the advantage that the device does not get in the way inside the vehicle, and can be easily attached and removed. The "housing" may be, for example, a housing integrated with the OBD connector.

[0053] <Configuration Example 14> The invention of configuration example 14 is a program for causing a computer to realize the functions of the device according to any one of configuration examples 1 to 13.

[0054] For example, the above-mentioned configuration examples may be combined to the extent that no contradiction occurs. Also, the components described in each configuration example may be combined to configure an apparatus. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0056] FIG. 1(a) shows a vehicle 10, and FIG. 1(b) shows a remote control key 30 attached to the vehicle 10. The inside of the vehicle 10 is referred to as the interior 10a, and the outside of the vehicle 10 is referred to as the exterior 10b. FIG. 2(a) shows the appearance of an OBD adapter 40. FIG. 2(b) shows an enlarged view of a dip switch 45 of the OBD adapter 40. FIG. 2(c) shows the function of the dip switch 45. FIG. 3 shows the hardware configuration of the vehicle 10 and the OBD adapter 40 connected to the vehicle 10.

[0057] [Vehicle configuration] The vehicle 10 has five doors (a driver's door 11a, a passenger's door 11b, a rear right door 11c, a rear left door 11d, and a rear door 11e).

[0058] The driver's door 11a, the passenger's door 11b, and the rear door 11e are doors that swing open on one side around a hinge and can be opened and closed manually. The right rear door 11c and the left rear door 11d are electric sliding doors that slide on a rail (not shown) by the driving force of a motor to open and close.

[0059] The doors 11a to 11e each include a door lock member 12a to 12e, an actuator 13a to 13e, and an opening / closing sensor 14a to 14e.

[0060] The door lock members 12a to 12e are mechanical members for locking and unlocking the doors by engaging with the body of the vehicle 10. When the doors 11a to 11e are locked, they cannot be opened by operating the door knobs, and when the doors are unlocked, they can be opened by operating the door knobs. Putting the door lock members 12a to 12e in a state where they can engage with the body is called "lowering" the door lock members 12a to 12e, and putting them in a state where they cannot engage with the body is called "raising" the door lock members 12a to 12e. The door lock members 12a to 12e can be raised and lowered by a user's manual operation or by driving the actuators 13a to 13e.

[0061] If the door lock members 12a to 12e are lowered while the doors 11a to 11e are closed, the doors 11a to 11e are locked. If the door lock members 12a to 12e are lowered and the door knob is pulled while the door 11a to 11e is closed, the doors 11a to 11e are also locked.

[0062] The opening / closing sensors 14a to 14e are sensors that detect whether the doors 11a to 11e are open or closed, and transmit signals indicating the detected opening / closing states.

[0063] The driver's door 11a and the passenger's door 11b have door knob switches 15a and 15b that can be operated from the outside of the vehicle 10b. The door knob switches 15a and 15b are switches that can be operated when an ID signal emitted by the remote control key 30 is in a receiving state, and can perform door locking and door unlocking operations. The door knob switches 15a and 15b transmit a first door lock command to the body control unit 25 when a door locking operation is performed, and transmit a first door unlock command to the body control unit 25 when a door unlocking operation is performed.

[0064] The rear right door 11c and the rear left door 11d include slide switches 16c and 16d and slide motors 17c and 17d.

[0065] The slide switches 16c and 16d can be operated from the outside of the vehicle 10b to open and close the slide doors. In response to the opening and closing operation, the slide switch 16c transmits a command to the body control unit 25 to open or close the left rear door, and the slide switch 16d transmits a command to the body control unit 25 to open or close the right rear door.

[0066] The slide motors 17c and 17d are power sources for opening and closing the slide switches 16c and 16d.

[0067] The remote control key 30 has an L button 31, a U button 32, a left button 33, and a right button 34. The remote control key 30 has an internal CPU, memory, a transmitting circuit, etc., and has a function of transmitting a signal indicating the operated button 31-34 and an ID signal stored in the memory in response to an operation of the above-mentioned buttons 31-34. Furthermore, the remote control key 30 has a function of transmitting an ID signal in response to an inquiry from the remote control receiving unit 18.

[0068] The remote control receiver 18 receives radio waves from the remote control key 30 and transmits to the body control unit 25 a signal corresponding to an operation performed on the remote control key 30. Specifically, when a signal of an operation of the L button 31 (door lock operation) and an operation of the U button 32 (door unlock operation) is received, a first door lock command and a first door unlock command are transmitted, respectively, and when a signal of an operation of the left button 33 and a right button 34 is received, a left rear seat side door open / close command and a right rear seat side door open / close command are transmitted, respectively.

[0069] The central door lock button 19 is an operating member installed on a center console in the vehicle interior 10a. The central door lock button 19 can be used to perform door lock and door unlock operations. When a door lock operation or a door unlock operation is performed, the central door lock button 19 transmits a second door lock command and a second door unlock command to the body control unit 25, respectively.

[0070] The security sensor 20 is a sensor that detects events that are considered necessary for security purposes, such as impacts or vibrations to the vehicle 10, or broken windows, and if such events are detected, the security sensor 20 sends an alert signal to the body control unit 25.

[0071] The vehicle 10 further includes a hazard lamp 21, a buzzer 22, a horn 23, etc. for issuing warnings and notifications to the user.

[0072] The vehicle 10 has a door lock control unit 24 and a body control unit 25 that control various devices of the vehicle 10 including the above-mentioned devices 13 to 23. The door lock control unit 24 and the body control unit 25 are each configured as a computer having a CPU and storage devices such as a ROM and a RAM (not shown). The door lock control unit 24 and the body control unit 25 configure a part of an ECU. The door lock control unit 24 and the body control unit 25 are connected to each other by a CAN bus 26, and can be connected to an external device such as an OBD adapter 40 via an OBD connector 27.

[0073] The door lock control unit 24 and the body control unit 25 transmit and receive signals (described below) between the OBD adapter 40 via the OBD connector 27, and the ECU provides vehicle information such as vehicle speed, engine speed, accelerator operation information, brake operation information, and steering operation information to external devices such as the OBD adapter 40 via the OBD connector 27.

[0074] The actuators 13a to 13e and the like are connected to the door lock control unit 24, and the opening / closing sensors 14a to 14e, the door knob switches 15a and 15b, the slide switches 16c and 16d, the slide motors 17c and 17d, the remote control receiver 18, the central door lock button 19, the security sensor 20, the hazard lamps 21, the buzzer 22, the horn 23 and the like are connected to the body control unit 25. The door lock control unit 24 and the body control unit 25 control these devices to realize various functions described below.

[0075] [OBD adapter configuration] 2, the OBD adapter 40 has a box-shaped housing 41. The housing 41 is made of a material having an appropriate strength, such as plastic. The housing 41 has connection parts 42, 43 and a DIP switch 45 on its front, rear, side and top surfaces, respectively.

[0076] The connection part 42 has a shape and structure that allows the OBD connector 27 to be detachably attached. The connection part 43 has a shape and structure that allows the connection part 44a at one end of the device connection connector 44 to be detachably and rotatably attached. An in-vehicle device such as a drive recorder, a radar detector, or a car navigation system can be attached to the other end of the device connection connector 44. Since the connection part 44a is detachable, it is possible to save space inside the vehicle by removing the device connection connector 44 when the in-vehicle device is not in use. Since the connection part 44a of the device connection connector 44 can be rotatably attached relative to the connection part 43, the convenience of wiring arrangement, etc. is improved.

[0077] The dip switch 45 has four setting switches numbered 1 to 4 for setting the operation of the control unit .

[0078] 3, the OBD adapter 40 has an internal control unit 46. The control unit 46 is configured as a computer having a CPU and storage devices such as ROM and RAM (not shown). The second door lock signal (code of the second door lock signal) sent by the central door lock button 19 is the same regardless of the model of the vehicle 10, and the second door lock signal is stored in the storage device as a factory default setting.

[0079] The control unit 46 is electrically connected to the DIP switch 45. By attaching the connection unit 42 to the OBD connector 27, the control unit 46 is electrically connected to the CAN bus 10, and by attaching the device connection connector 44 to the connection unit 43, the control unit 46 is electrically connected to the device connection connector 44.

[0080] [Vehicle 10 Functions] The functions of the vehicle 10 described below are realized by a door lock control unit 24 and a body control unit 25, which are computers, controlling the devices 13-23 etc. according to programs stored in storage devices such as ROM and RAM, or by sending and receiving signals between the devices 13-23 etc. The vehicle 10 has a door sliding function, an open / close determination function, a lock unit driving function, a door lock function, first to third notification functions, an alarm sound suppression function, an alert state setting function, an in-lock prevention function, etc.

[0081] The door slide function is a function in which the body control unit 25 opens and closes the right rear seat side door 11c and the left rear seat side door 11d. Specifically, when the body control unit 25 receives a right rear seat side door opening / closing command from the slide switches 16c, 16d or the remote control receiver 18, the body control unit 25 controls the right rear seat side door 11c to be opened or closed by the slide motor 17c. That is, if the right rear seat side door 11c is open, it is controlled to be closed, and if it is closed, it is controlled to be opened. When the body control unit 25 receives a left rear seat side door opening / closing command, the body control unit 25 controls the right rear seat side door 11c to be opened or closed by the slide motor 17d. That is, if the right rear seat side door 11d is open, it is controlled to be closed, and if it is closed, it is controlled to be opened. It takes 10 seconds for the door slide function to close the right rear seat side door 11c and the left rear seat side door 11d in the fully open state.

[0082] The open / close determination function is a function that determines the open / closed states of the doors 11a to 11e based on signals from the open / close sensors 14a to 14e when the body control unit 25 receives a first door lock command from the door knob switches 15a, 15b or the remote control receiver 18. The open / close determination function includes an open / close notification function that, when an open / close inquiry signal is received from the control unit 46 of the OBD adapter 40, the body control unit 25 transmits an open / close response signal indicating the open / closed states of the open / close sensors 14a to 14e to the control unit 46.

[0083] The lock unit driving function is a function in which the door lock control unit 24 raises and lowers the door lock members 12a to 12e by driving the actuators 13a to 13e.

[0084] The door lock function includes a first door lock function, a first door unlock function, a second door lock function, and a second door unlock function.

[0085] The first door lock function is a function that the body control unit 25 executes when a first door lock command is received from the door knob switches 15a and 15b or the remote control receiving unit 18.

[0086] Specifically, when the body control unit 25 receives the first door lock command, it first determines whether the doors 11a to 11e are open or closed using an open / close determination function.

[0087] Then, when it is determined that all of the doors 11a to 11e are closed, the body control unit 25 transmits a first door lock signal to the door lock control unit 24 via the CAN bus 26. The door lock control unit 24, which has received the first door lock signal, lowers the door lock members 12a to 12e using the lock unit driving function. As a result, all of the doors 11a to 11e are locked.

[0088] On the other hand, when it is determined that any of the doors 11a to 11e is open, the body control unit 25 does not transmit the first door lock signal, and cancels the door lock command received from the remote control receiving unit 18. Therefore, the lock unit driving function is not activated, and the doors are not locked.

[0089] The first door unlock function is a function in which, when the body control unit 25 receives a first door unlock command from the door knob switch 15a, 15b or the remote control receiver 18, the body control unit 25 transmits a first door lock signal to the door lock control unit 24 via the CAN bus 26, and the door lock control unit 24, having received the first door lock signal, lifts the door lock members 12a to 12e using the lock unit drive function, thereby unlocking the doors 11a to 11e.

[0090] The second door lock function is a function in which, when the body control unit 25 receives a second door lock command from the central door lock button 19, the body control unit 25 transmits a second door lock signal to the door lock control unit 24 via the CAN bus 26, and the door lock control unit 24, having received the second door lock signal, lowers the door lock members 12a to 12e using the lock unit driving function. The second door lock function is executed regardless of whether the doors 11a to 11e are open or closed. When the second door lock function is executed while the doors 11a to 11e are closed, the door lock units 12a to 12e engage with the vehicle body to lock the doors. When the doors 11a to 11e are open, the door lock units 12a to 12e do not engage with the vehicle body, and the doors are not locked.

[0091] The second door unlock function is a function in which, when the body control unit 25 receives a second door unlock command from the central door lock button 19, the body control unit 25 transmits a second door lock signal to the door lock control unit 24, and the door lock control unit 24, upon receiving this, uses the lock unit drive function to lift the door lock units 12a to 12e and unlock the doors 11a to 11e.

[0092] The door lock function described above allows the user to lock all of the doors 11a to 11e at once by operating the door knob switches 15a, 15b, the remote control key 30, or the central door lock button 19. However, since the vehicle 10 does not have a door lock reservation function, if the user performs a door lock operation while any of the doors 11a to 11e is open and the OBD adapter 40 is not used, the door will remain unlocked.

[0093] The first notification function is a function in which the body control unit 25 blinks the hazard lamps 21 a certain number of times (for example, 2 to 3 times) on the condition that the doors are locked at the time point after the first door lock function is executed. This function allows the user to confirm that the doors have been locked by the first door lock function.

[0094] The second notification function is a function in which the body control unit 25 causes the buzzer 22 to emit a "beep, beep, beep" alarm sound on the condition that the doors are not locked after the first door lock function is executed.

[0095] The alarm sound suppression function is a function that stops the alarm sound of the buzzer 22 when the body control unit 25 receives a first door unlock signal while an alarm sound is being emitted by the second notification function.

[0096] As described above, if the doors are not locked despite the first door lock function being executed, the user can be informed of this by the alarm sound generated by the second notification function. However, to stop the alarm sound, the user must perform the door unlock operation using the door knob switch 15a, 15b or the remote control key 30, and some users may find this operation troublesome.

[0097] The third notification function is a function for causing the hazard lamps 21 to flash at high speed for a certain period of time when the body control unit 25 receives an emergency signal from the control unit 46. The flashing of the hazard lamps 21 by the third notification function is performed at a higher speed than that by the first notification function, thereby making it possible to call attention to the surroundings of the vehicle 10.

[0098] The alert state setting function is a function in which the body control unit 25 transitions to an alert state on the condition that the doors are locked at the time point after the execution of the first door lock function. When the body control unit 25 is in an alert state and an alert signal is sent from the security sensor 20, the body control unit 25 makes the horn 23 sound at a high volume. This notifies the surroundings of abnormalities such as theft and vehicle break-in, and improves the security of the vehicle. Furthermore, when the body control unit 25 is in an alert state, even if the body control unit 25 receives a second door unlock command from the central door lock button 19, the body control unit 25 does not transmit a second door unlock signal to the door lock control unit 24 and cancels the second door unlock command. This means that even if a door unlock operation is performed on the central door lock button 19 using a wire or the like from outside the vehicle 10b, the doors are not unlocked, and therefore the security of the vehicle can be improved.

[0099] The lock-out prevention function is a function in which the body control unit 25 judges whether the remote control key 30 is inside the vehicle 10a based on the reception state of the ID signal transmitted by the remote control key 30 in response to an inquiry from the remote control receiver 18, and causes the door lock control unit 24 to unlock the doors 11a to 11e if it is judged that the remote control key 30 is inside the vehicle. The lock-out prevention function is executed when the user locks the doors by operating the central door lock button 19, gets out of the vehicle 10, and closes the driver's door 11a while pulling the door handle. This makes it possible to prevent a lock-out state in which the doors are locked with the remote control key 30 left inside the vehicle 10a. The lock-out prevention function is also executed when the body control unit 25 receives an lock-out prevention signal from the control unit 46, which will be described later.

[0100] [OBD Adapter 40 Functions] The OBD adapter 40 has a door lock reservation function, an equipment connection connector output function, a vehicle speed-sensing door lock function, and an emergency signal function. These functions are realized when, with the connection unit 42 attached to the OBD connector 27, the control unit 46, which is a computer, controls the vehicle 10 according to a program stored in a storage device such as a ROM or RAM, or transmits and receives signals to and from the vehicle 10 via the OBD connector 27.

[0101] The door lock reservation function is a function in which the control unit 46 executes a door lock reservation process shown in Fig. 4. The door lock reservation function is executed when the switch number 4 of the DIP switch 45 is set to ON.

[0102] As shown in the figure, when the door lock reservation process starts at "START", in S100, the control unit 46 determines whether the OBD adapter 40 is still attached, and if not (N), executes the initial setting process in S200. This determination can be made based on whether S100 has been executed for the first time since the factory-shipped OBD adapter 40 was attached to the vehicle 10, or whether the first door lock signal and the first door unlock signal are stored in the memory device of the OBD adapter 40, etc.

[0103] Fig. 5 shows details of the initial setting process of S200. In order to enable the initial setting process, it is assumed that the user is instructed by the instruction manual or the like to close all the doors 11a to 11e when using the vehicle for the first time, lock the doors using the remote control key 30 or the door knob switches 15a and 15b, and then unlock the doors. In the following, the remote control key 30 or the door knob switches 15a and 15b will be referred to as the "remote control key 30, etc."

[0104] When S200 starts, in S210, the control unit 46 judges whether all the doors 11a to 11e are closed, and if the answer is negative (N), repeats S210. When the user closes all the doors 11a to 11e, the judgment in S210 becomes positive (Y), and the process proceeds to S220.

[0105] The determination of the open / closed states of the doors 11a to 11e in S210, S300, S310, and S330 is made based on an open / closed response signal transmitted by the body control unit 25 in response to an open / closed inquiry signal transmitted by the control unit 46 to the body control unit 25.

[0106] In S220, the system waits for a door lock operation by the user using the remote control key 30 or the like. When the door lock operation is performed, the system proceeds to S230, where the control unit 46 acquires a first door lock signal transmitted from the body control unit 25 to the door lock control unit 24, and stores the acquired first door lock signal (signal code) in a storage device of the OBD adapter 40. Note that the control unit 46 acquiring the first door lock signal transmitted from the body control unit 25 to the door lock control unit 24 is referred to as "the control unit 46 receiving a door lock instruction from the body control unit 25."

[0107] In S240, the system waits for a door unlock operation by the user using the remote control key 30 or the like. When the door unlock operation is performed, the system proceeds to S250, where the control unit 46 acquires a first door unlock signal transmitted from the body control unit 25 to the door lock control unit 24, and stores the acquired first door unlock signal (signal code) in the storage device of the OBD adapter 40.

[0108] By executing S230, the initial setting process (S200) is completed (END). When S200 is completed or the determination in S100 is affirmative (Y), the process proceeds to S300.

[0109] In S300, it is determined whether the driver's door 11a is closed, and if the result is negative (N), the process proceeds to S100. This is because it is not expected that the user intends to make a door lock reservation with the driver's door 11a open.

[0110] If the determination in S300 is positive (Y), then in S310 it is determined whether any of the doors 11b to 11e other than the driver's door 11a are open, and if the determination is negative (N), the process proceeds to S100. Therefore, when all the doors 11a to 11e are closed, the process loops from S100 to S300 to S310 to S100. If the user performs a door lock operation using the remote control key 30 or the like during this loop, the doors 11a to 11e are locked by the first door lock function of the vehicle 10.

[0111] If the determination in S310 is positive (Y), in S320, the control unit 46 determines whether or not a door lock operation has been performed using the remote control key 30, etc. Specifically, if the control unit 46 has received a door lock instruction from the body control unit 25, a positive (Y) determination is made and the process proceeds to S330, and if not, a negative (N) determination is made and the process proceeds to S100.

[0112] In addition, if the judgment of S310 is positive (Y), when any of the doors 11b to 11e is open and a door lock operation is performed using the remote control key 30 or the like, the second notification function of the vehicle 10 is activated and an alarm sound is emitted from the buzzer 22.

[0113] In S330, the control unit 46 transmits the first door unlock signal stored in S250 to the body control unit 25. This activates the alarm sound suppression function of the vehicle 10, and the alarm sound of the buzzer 22 can be stopped.

[0114] In S340, the control unit 46 judges whether all the doors 11a to 11e are closed within a predetermined timer set time. This judgment is made based on an open / close response signal transmitted from the body control unit 25 in response to an open / close inquiry signal from the control unit 46. The timer set time is set as a normally expected time from when a user performs a door lock operation using the remote control key 30 or the like until when the doors 11a to 11e are closed. Since the time required for the door sliding function to close the right rear seat side door 11c and the left rear seat side door 11 is 10 seconds, the timer set time is set to 10 seconds at the shortest.

[0115] If the determination in S340 is negative (N), the process proceeds to S350, where the control unit 46 transmits the first door lock signal stored in S230 to the door lock control unit 24. As a result, the first door lock function is executed in the vehicle 10, but since any of the doors 11a to 11e is open, the second notification function of the vehicle is activated and an alarm is emitted from the buzzer 22. This notifies the user that the door lock (S360, S370) was not performed by the door lock reservation function, and prevents the user from leaving the vehicle 10 without the doors being locked. When S350 is completed, the process proceeds to S100.

[0116] If the determination in S340 is affirmative (Y), the process proceeds to S360, where the control unit 46 transmits the second door lock signal stored in the storage means to the door lock control unit 24. This activates the second door lock function of the vehicle 10, and all of the doors 11a to 11e are locked.

[0117] In S370, the control unit 46 transmits the first door lock signal stored in S230 to the door lock control unit 24. This activates the first door lock function of the vehicle 10, and all of the doors 11a to 11e are locked. Since the doors are locked in S360 and S370, the reliability of the door locking is improved.

[0118] Note that the state after execution of S370 is the state after execution of the first door lock function, and the doors are locked, so the first notification function and the alert state setting function of the vehicle 10 are activated. The flashing of the hazard lamps 21 by the first notification function allows the user to confirm that the doors are locked even from a distance, and the user can start to leave the vehicle 10 immediately after operating the door lock using the remote control key 30 or the like. In addition, the alert state setting function sets the body control unit 25 to an alert state, thereby improving the crime prevention of the vehicle.

[0119] In the next S380, it is confirmed whether the remote control key 30 is inside the vehicle 10, and if it is, the doors 11a to 11e are unlocked. Specifically, the control unit 46 transmits an unlocking prevention signal to the body control unit 25, and the body control unit 25 receiving this signal executes the locking prevention function. This prevents the door from becoming locked even if the user accidentally places the remote control key 30 inside the vehicle 10a between S320 and S380.

[0120] After S380 is executed, the process proceeds to S100, and the above-mentioned process is repeatedly executed.

[0121] The door lock reservation function relieves the user from the inconvenience of being unable to lock the doors using the remote control key 30 or the like until all the doors 11a to 11e are closed. For example, if only the right rear seat door 11c is open, the door will be locked after the right rear seat door 11c is closed by the door slide function by performing the opening and closing operation of the slide switch 16c and the door lock operation using the remote control key 30 or the like (in any order). The same applies to the right rear seat door 11d. Even if the door lock operation is performed using the remote control key 30 or the like while the door 11a, 11b, or 11e is open, the door will be locked if the user closes the door 11a, 11b, or 11e within the timer time (S360, S370).

[0122] The device connection connector output function is executed when switch number 1 of DIP switch 45 is set to on, and is a function that connects the OBD connector 27 to device connection connector 44 via the OBD adapter 40. Other in-vehicle devices such as a drive recorder, radar detector, car navigation system, etc. can be connected to device connection connector 44. The device connection connector output function makes it possible to use the OBD adapter 40 and other in-vehicle devices together with a single OBD connector 27, and allows the other in-vehicle devices to send and receive signals to and from the OBD connector 27.

[0123] The in-vehicle sensory door lock function is executed when the switch number 2 of the DIP switch 45 is set to ON, and the control unit 46 monitors the vehicle speed received through the OBD connector 27, and when the vehicle speed exceeds 30 km, the control unit 46 transmits a second door lock signal stored in the storage device to the door lock control unit 24. Upon receiving the second door lock signal, the door lock control unit 24 locks the doors 11a to 11e using the second door lock function. This improves safety during high-speed driving.

[0124] The emergency signal function is executed when switch number 3 of the DIP switch 45 is set to ON, and is a function in which the control unit 46 monitors the brake operation information received by the OBD connector 27, and transmits an emergency signal to the body control unit 25 when it is determined that the braking has been sudden. The body control unit 25, which has received the emergency signal, flashes the hazard lamps 21 at high speed using the third notification function. This can be expected to have an effect of preventing accidents by calling the attention of those around the vehicle when the vehicle is suddenly braked.

[0125] The above describes preferred embodiments. However, the shapes, dimensions, materials, functions, operation modes, control modes, control parameters, operation modes, etc. of the devices, systems, and programs or their elements and components in the above embodiments are described as examples and may be changed.

[0126] For example, the door lock reservation function in the above embodiment determines whether all the doors 11a to 11e are closed in S340, and locks the doors when the determination is affirmative (Y) (S360, S370), but it is also possible to omit S340, wait for a certain delay time to elapse from the time when the determination in S320 becomes affirmative (Y), and automatically lock the doors when the delay time has elapsed (S360, S370). In this case, it is possible to omit S350, but even in that case, if any of the doors 11a to 11e are open, the door lock members 12a to 12e are simply lowered in S360 and S370, but the doors are not locked, so that the second notification function is activated when S370 is executed, and the user is notified by emitting a sound from the buzzer 22.

[0127] In addition, in the above embodiment, an example was shown in which the open / closed state of the driver's door 11a and the other doors 11b to 11e was determined in two steps (S300 and S310). However, these steps may be combined into a single step in which it is determined whether any of the doors 11a to 11e are open, and if any are open, the process proceeds to S320, and if all are closed, the process proceeds to S100.

[0128] In the above embodiment, the vehicle 10 has been described as having a hardware configuration having the door lock control unit 24 and the body control unit 25 separately, but the vehicle is not limited to this. For example, as another type of vehicle, the vehicle 10 may have a hardware configuration as shown in FIG. 6. The vehicle in FIG. 6 does not have the door lock control unit 24, and the body control unit 25 controls the actuators 13a to 13e. The smart key control unit 28 is a functional block that transmits and receives signals by the remote control receiving unit 18.

[0129] 6 does not have the door lock control unit 24, the body control unit 25 does not transmit the first door lock signal, the second door lock signal, the first door unlock signal, and the second door unlock signal to the door lock control unit 24 as described in the above embodiment. However, when the first door lock function, the second door lock function, the first door unlock function, and the second door unlock function are operated, the first door lock signal, the second door lock signal, the first door unlock signal, and the second door unlock signal are transmitted from the body control unit 25 to the CAN bus 26. Therefore, the OBD adapter 40 can acquire the first door lock signal and the second door lock signal via the CAN bus 26 (S220, S240, S320). In addition, when the body control unit 25 receives the first door lock signal, the second door lock signal, the first door unlock signal, and the second door unlock signal from the CAN bus 26, the body control unit 25 executes the first door lock function, the second door lock function, the first door unlock function, and the second door unlock function. Therefore, the vehicle 10 executes the first door unlock function, the second door lock function, and the first door lock function by transmitting the first door unlock signal, the second door lock signal, and the first door lock signal (S330, S360, S370) from the OBD adapter 40 to the body control unit 25. Therefore, the door lock reservation function of the OBD adapter 40 functions substantially similarly to the embodiment described above.

[0130] In addition, in the above embodiment, the vehicle 10 is described under the assumption that the central door lock button 19 is located in the center console, but the central door lock button 19 may be installed in the armrest area on the inside of the driver's side door 11a, for example.

[0131] A door unlock reservation function may also be provided. For example, after execution of S380 in FIG. 4 of the door lock reservation function described above, the fact that the door has been locked by the door lock reservation function may be stored in the control unit 46, and when it is determined that the remote control key 30 has once moved away from the vehicle and then approached again based on a signal indicating the communication availability state between the remote control key 30 and the remote control receiver 18 sent from the body control unit 25 to the CAN bus 26, a signal to cause the body control unit 25 to release the door lock may be output to the CAN bus 26, and the process may return to S100. In particular, it is preferable to obtain information on which door was last closed, and release the door lock of that door. Also, if the door is a sliding door, a signal to release the door and open the sliding door may be output to the CAN bus 26. Vehicles that are originally equipped with the so-called door unlock reservation function are limited to some models, such as the latest luxury cars, but a function similar to the reservation of door unlocking can be realized in vehicles that do not have such a function. Furthermore, with this configuration, unlike the so-called door unlock reservation function, it is possible to simply reserve door locking when leaving the vehicle, and when returning to the vehicle and approaching it again, the vehicle doors can be unlocked and the sliding door opened without the user having to operate the remote control key 30, such as by explicitly reserving door unlocking.

[0132] The components of the modified examples and the embodiments, and the elements and ideas described in the Means for Solving the Problems may be combined in any manner to form an embodiment. The contents of the invention are not limited to those described in the present embodiment.
