Description

  The present invention relates to a control device for an in-vehicle electronic device.

  In recent automobiles, a navigation device is often mounted as an on-vehicle electronic device that displays a current position together with a road map on a screen and sets and displays an appropriate route from the current location to the destination. In the case of such a navigation device, as a switch for operation, a mechanical switch provided near the screen of the display device or a soft switch using a touch panel superimposed on the screen is provided, and these switches are operated from the driver's seat. It is possible to do. However, since it is not desirable for the driver to operate these switches while driving, input that requires complicated procedures such as map search in navigation, destination setting, phone number input, etc. The operation is restricted during driving.

  However, in the case of the above configuration, passengers other than the driver are also restricted in operation during traveling, which is inconvenient. Therefore, Patent Document 1 discloses a technology for providing a release switch for releasing the operation restriction at the end of the passenger seat that is out of the reach of the driver, and accepting the operation if the release switch is pressed. ing. Further, Patent Document 2 discloses a technique for providing an operation by the passenger only when a release switch is provided on the left and right of the steering wheel and the driver is operating both the left and right release switches at the same time using both hands. ing.

JP-A-5-164565 JP 11-198745 A

  However, these release switches are in a place that can be easily touched by the occupant, and are also mechanically simple. Therefore, unauthorized modification such that the release switch is always on, such as taped release switch, is possible. There is a possibility of being. When such a modification is made, the operation restriction is always released, and the driver can perform the operation while driving, and the original function of the operation restriction may be lost.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a control device for an in-vehicle electronic device that can prevent an unauthorized operation restriction from being released.

In order to solve the above problems, a control device for an in-vehicle electronic device according to the present invention includes:
Operation restriction means for prohibiting or invalidating operation on the in-vehicle electronic device according to the running state of the vehicle, and restriction release means for releasing control for prohibiting or invalidating the device operation by the operation restriction means. In the control device for in-vehicle electronic devices
A starting operation detecting means for detecting an operation inevitably executed by a user when starting the engine of the vehicle;
When the operation is detected by the start operation detecting means, if the control is released by the restriction releasing means, the restriction release prohibiting means for prohibiting the control release by the restriction releasing means,
Characterized by comprising

  Since the car is stopped when the engine is started, there should be no forced control of the electronic device (operation restriction control to the operation part of the electronic device), and there should be no need to use the restriction release operation part It is. Therefore, it is very unnatural that the restriction releasing operation unit is in operation when the engine is started, and the probability that the above-described unauthorized modification has been made is very high. Therefore, according to the above-described configuration of the present invention, in the vehicle in which the operation restriction to the electronic device is made, when the operation restriction has already been released at the time of starting the engine, this is determined as an unauthorized release of the operation restriction, The release of the operation restriction can be prohibited. As a result, unauthorized modification that constantly releases operational restrictions can be prevented, and even if such modifications are made, it is prohibited to cancel the operational restrictions due to the modifications. Functions.

  In the present invention, the “starting operation” may be an operation inevitably executed by the user when starting the vehicle engine, that is, an operation that can be specified as an indispensable operation for starting the engine. It is irrelevant whether the engine is actually started when the operation is performed. That is, the operation used for determining whether to restrict the operation restriction may be executed by being incorporated in a series of operations leading to engine start, or the series of operations is interrupted on the premise that the operation is executed. (In this case, the engine is not started).

The in-vehicle electronic device of the present invention is
A display unit for visually displaying information provided at a position visible from the driver's seat of the vehicle;
In order to use the device function on the premise of displaying information on the display unit, a device operation unit provided at a position operable from the driver's seat of the vehicle,
Traveling detection means for detecting the traveling state of the vehicle;
With
The operation restricting means defines a function corresponding to a predetermined device function of the device operating section as a restricting operation section that should restrict an operation by a driving driver, and the travel detecting means detects that the vehicle is traveling. In this case, the operation to the restricted operation part is prohibited or invalidated.
In order to enable the operation to the restricted operation unit by the passenger on the seat other than the driver seat in the state where the operation by the driver for the restricted operation unit is prohibited or invalidated by the operation restriction unit, An operation restriction release command means for issuing a prohibition or invalidation release command to the operation restriction means based on an operation state to a restriction release operation section provided separately from the restriction operation section.
The start operation detecting means is unavoidably executed when starting the engine of the vehicle, and the operation restriction is canceled triggered by an operation to a predetermined engine start unit or acquisition of information from an information output device carried by a vehicle occupant. Functions as a determination timing defining means for defining the determination timing of whether or not to permit the release command to the command means;
The restriction release prohibiting means includes an operation restriction release determining means for determining whether or not the restriction release operation unit is operating at a determination timing specified by the determination timing specifying means, and an operation for releasing the restriction by the operation restriction release determining means. When it is determined that the unit is in operation, it may be configured to include release command prohibiting means for prohibiting a release command by the operation restriction release command means.

  In-vehicle electronic devices are activated or initialized during the engine start sequence, so passengers in the front passenger seat operate the electronic devices predominantly after the engine has been started a little after the engine has started. Many. On the other hand, when the engine is started, the driver is concerned about the starting operation, and it is unlikely that the electronic device will be operated in parallel. According to the above configuration of the present invention, in a vehicle in which operation restriction during traveling (also referred to as traveling compulsion) is made, if the operation restriction has already been released when the engine is started, it is determined that this is an unauthorized operation restriction release. Thus, the release of the operation restriction can be prohibited. As a result, unauthorized modification such that the operation restriction is always released can be prevented, and even if such modification is made, the restriction of the operation restriction by modification is prohibited. Functions.

  In the control apparatus for in-vehicle electronic equipment according to the present invention, the restriction release prohibiting means sets the release prohibition state to the state where the release prohibition state is not prohibited from being released when the control release by the restriction release means is already prohibited by itself. After executing the reset process, it may be determined whether or not the control is released by the restriction release means, and if the release is made, the release may be prohibited again. When the operation detected by the detecting means involves engine start, the release command prohibiting means is in the prohibited state when the engine is stopped and restarted once while the release command is prohibited by the operation restriction release command means. May be canceled.

  According to the above configuration, even if the release of the operation restriction is prohibited, if the operation that is the trigger for starting the execution of the prohibition control is executed again, in any process before the operation execution The prohibition control is released (reset), and it is possible to return to a state in which the operation restriction can be released again. For example, if the operation to be triggered is accompanied by engine start, once the engine is stopped, the prohibited state is triggered by a predetermined step in the engine stop or subsequent engine restart sequence. It is reset and it can return to the state which can cancel | release a restriction | limiting of operation again. As a result, in the case where the operation restriction release operation to the electronic device is performed unintentionally during the engine start sequence even though the unauthorized modification is not performed, the current state in which the restriction release is prohibited is reached. The operation performed by the user is repeated again. For example, when the operation is an operation accompanied by the start of the engine, the operation restriction releasing function can be easily restored simply by restarting the engine. In short, if the engine start operation is performed again from the beginning, the operation restriction release function can be restored. Also, even if unauthorized modification has been made, the operation restriction release function can be restored by re-starting the engine starting operation from the beginning after eliminating the modified state.

  The on-vehicle electronic device control device of the present invention may include alarm output means for outputting an alarm to the driver when the release command is prohibited by the release command prohibiting means.

  According to the above configuration, the driver or passenger can recognize that the operation restriction during traveling cannot be released, and can notify / warn the possibility that it is due to unauthorized modification. . As a result, the driver who is cheating is encouraged to revise the cheating, and the cause is recognized even when the operation restriction is unintentionally released at the time of engine start instead of cheating. It becomes possible to prompt the engine to restart again.

  In the control apparatus for on-vehicle electronic equipment of the present invention, the operation detected by the start operation detecting means or the determination timing specified by the determination timing specifying means is determined after the key is inserted into the engine start key cylinder of the automobile. It may be a predetermined operation or timing in the sequence until the rotation operation to the start position.

  Thereby, it is possible to determine whether or not there is an unauthorized restriction release at the stage of the engine start operation when the vehicle is stopped, and in the determination, a predetermined step in the key operation as described above may be used as a trigger. it can. For example, either when the key is inserted into the key cylinder, when the key is operated to the accessory position, when the key is operated to the position where the ignition is turned on, or when the key is operated to the engine start position The signal generated at this timing can also be used as a determination timing defining signal that defines the timing for determining whether or not there is an illegal restriction release, and the determination can be started using detection of the signal as a trigger.

  On the other hand, in the control device for an in-vehicle electronic device according to the present invention, the vehicle performs ID authentication for collating the ID of the information output device carried by the occupant with the ID on the vehicle side, and performs steering unlocking and There is a case where an engine start method is employed in which the engine operation prohibition state is released and the engine is started by pressing the engine start switch by depressing the brake pedal from this state. In this case, the operation detected by the start operation detecting unit or the determination timing defined by the determination timing defining unit may be made based on a predetermined operation or timing in the engine start method. In particular, the operation detected by the start operation detecting means or the determination timing defined by the determination timing defining signal generating means is the engine start method at the time of ID authentication, when the steering is unlocked, when the engine operation prohibited state is released, The operation or timing can be set either when the pedal is depressed or when the engine start switch is pressed.

  In recent automobiles, an engine start system called a smart and push start system that does not use a key may be employed. Even in such an engine starting type vehicle, a predetermined step of the engine starting sequence can be used as a trigger for determining the presence or absence of an illegal operation restriction release command. For example, a signal generated at a predetermined step at the time of starting the engine is detected, and this signal is also used as a determination timing defining signal that defines the timing at which the above determination is performed, and detection of the signal is used to start the determination. It can be a trigger.

  The operation restricting means is for prohibiting or invalidating the operation to the restricting operation part that should restrict the operation by the driver among the device operation parts of the in-vehicle electronic device, and the restriction releasing means to the restricting operation part. A release command for canceling the prohibition or invalidation of the operation can be performed based on the operation state of the restriction release operation unit, and the operation to the limited operation unit can be performed by the release command. Furthermore, in order to use a display unit for visually displaying information provided at a position visible from the driver's seat of the vehicle and a device function based on the display of information on the display unit, the driver's seat of the vehicle A device operation unit provided at an operable position, and a travel detection unit that detects a travel state of the vehicle, and the operation restriction unit is a unit that corresponds to a predetermined device function of the device operation unit. The restriction operation unit is defined as a restriction operation unit that should restrict the operation by the driver, and when the vehicle is detected to be traveling by the traveling detection unit, the operation to the restriction operation unit is prohibited or invalidated, and the restriction release unit In order to allow the passenger on the seat other than the driver's seat to operate the restricted operation unit in a state where the operation by the driver with respect to the restricted operation unit is prohibited or invalidated by the operation restriction unit, When Based on the operation state of the provided separately from restriction release operation section, to the operation limiting means, can be made to perform release command of prohibited or disabled.

  According to the above configuration, the operation unit for performing an operation in which the driver's consciousness is easily directed during driving is a limited operation unit, and when there is a person in the passenger seat, an operation that allows the person to operate the limited operation unit By providing the unit as a restriction release operation unit, it is possible to execute the functions performed by each unit. Therefore, operations restricted during traveling can be operated by other passengers, which is convenient.

  In the on-vehicle electronic device control device of the present invention, the restriction release operation unit is a release switch provided at a position where operation from the driver's seat is impossible and operable by a passenger other than the driver's seat. The operation restriction release command means may issue a release command when the release switch is in the pressed state. In this case, the release switch can be provided at a position where it can be operated by the passenger in the passenger seat.

  According to the above configuration, the restriction release operation unit (release switch) for releasing the operation restriction during traveling of the vehicle is a position that cannot be touched by the driver sitting in the driver's seat (for example, the inside of the door facing the passenger seat) ) Is not possible to be released by the driver, while passengers sitting in other seats press the release switch to release the operation restriction while driving the vehicle and operate the restricted operation unit. Is possible. For example, the switch operation of the navigation device during traveling of the vehicle is effective because any operation can be performed even if the passenger is sitting in the passenger seat next to the driver instead of the driver.

  In the on-vehicle electronic device control device according to the present invention, the restriction release operation unit is a handle operation detection unit that detects whether or not the driver is holding the handle with both hands, and the driver grips the handle with both hands. When the operation is detected by the handle operation detection unit, the operation restriction release command means issues a release command, and when the handle operation detection unit detects that at least one hand of the driver is detached from the handle, the operation restriction is released. The command means may not perform a release command.

  According to the above configuration, when the steering operation detection unit detects a driver's two-handed operation while the vehicle is traveling, that is, when the driver cannot perform other operations, the limiting operation by a passenger other than the driver Passengers sitting in other seats, such as passenger seats, can cancel the operation restriction without particularly operating the operation unit for releasing the restriction. It will end. Specifically, a release switch for releasing the restriction can be provided on the left and right of the handle as the handle operation detection unit. In this case, in order to allow the passenger to operate the restricting operation unit while traveling, the driver must operate the left and right release switches with the left and right hands. The situation can not be. In addition, an image recognition unit that recognizes the driver's hands with the handle operation detection unit is provided so that the passenger can operate the restricted operation unit when it detects that the driver is operating the handle with both hands. It can also be.

  In the control device for an in-vehicle electronic device according to the present invention, the restriction operation unit may execute or select a predetermined navigation function in the navigation device, or may execute a telephone function. In addition, the display unit may be switched to a television screen. In particular, in the case of a navigation function, the navigation function performed by the restriction operation unit can be a destination setting function.

  Among the functions performed by the operation of the device operation unit, particularly for the navigation function, telephone function, and TV screen channel switching function as described above, the operator needs to concentrate on the screen and the operation unit. However, it is not desirable for the driver to be immersed in such an operation. Therefore, it is effective that an operation unit for operating these functions is included as a limited operation unit in which operations are restricted during vehicle travel.

  Hereinafter, an embodiment of a control device for an in-vehicle electronic device according to the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration of a control device for an in-vehicle electronic device. 1 includes a display device 1, an operation switch group 2, a vehicle speed sensor 3, a travel forcible release instruction input unit 4, a start operation unit 5, a main ECU 6, and various ECUs 71 to 76. Configured.

  As shown in FIG. 2, the display device 1 includes a display unit 1 a such as a liquid crystal display that visually displays information, and an operation switch group 2 described later. The display unit 1a displays a navigation screen including a screen for displaying a map and the current position or a screen for setting a destination, a screen for a television, a screen for a radio, a screen for a telephone, a screen for a music CD and a cassette, etc. It is. As shown in FIG. 3, the display device 1 is disposed at the center of the instrument panel in the passenger compartment so that a driver 80 sitting in the driver's seat and an occupant 81 sitting in the passenger seat are visible. .

  As shown in FIG. 2, the operation switch group 2 is configured as a mechanical switch 2 a and is provided as a device operation unit on the left and right sides of the display unit 1 a of the display device 1. These operation switches 2a include various operation switches for using a navigation function, a TV function, a radio function, a viewing function such as a music CD and a cassette, and a changeover switch for switching these functions. Is arranged so that it can be manually operated by both passengers sitting in the driver's seat and passenger seat. In addition, such an apparatus operation part can also be comprised as a touch switch (soft button) integrated with the display part 1a. In this case, a transparent touch panel is overlaid on the display unit (screen) 1a, and a finger touches a soft button area (a button image is displayed at a corresponding position on the lower screen) set on the touch panel. The button is recognized as being energized. Of these operation switches 2a, a predetermined switch is a limited operation unit that prohibits or disables the operation during driving. For example, while driving, it is not desirable for the driver to be immersed in complicated input operations such as map search, destination setting, telephone number input, and switching to a TV screen among navigation functions. The operation is restricted in advance so as to be prohibited only while the vehicle is running. In the case of a mechanical switch, the switch operation is invalidated (for example, the output of the operation signal is stopped or the reception of the operation signal is rejected), and the touch operation is performed. In the case of a switch, the switch is erased from the screen so that the switch cannot be operated, or the switch color is toned down to lock the soft button so that the input operation is disabled. In the present embodiment, the operation switch 2a that constitutes the device operation unit is provided with a restriction operation unit that should be restricted while the vehicle is running, and the restriction operation unit has a predetermined display screen. The operation is prohibited or invalidated in the displayed state.

  The vehicle speed sensor 3 is a travel detection unit that detects a travel state of the vehicle, and is a travel detection unit that detects a rotation amount of the wheel and outputs a travel pulse. A travel pulse indicating the travel state of the vehicle is output to the main ECU 6. The travel detection means of the present invention is not necessarily limited to a vehicle speed sensor, and an acceleration sensor, an angular velocity sensor, or the like may be used as long as it can detect at least whether the vehicle is traveling. Is possible. In the car navigation device, since the current position of the car can be monitored in real time by GPS (Global Positioning System), it is possible to detect the running by detecting the time change of the position.

  As shown in FIG. 3, the operation restriction release input unit (restriction release operation unit) 4 is a release switch 4 a provided on the door portion on the passenger seat side where the driver sitting in the driver's seat does not reach. When the release switch 4a is in a pressed state, the above-described operation restriction during traveling of the vehicle is released, and all the operation switches 2 can be operated. Therefore, even when the vehicle is traveling, the passenger on the passenger side actively activates the release switch 4a, so that the operation switch 2a can be operated without being restricted even when traveling. The operation restriction release input unit 4 is not limited to the release switch 4a as described above. In addition, the operation restriction release input unit 4 is a handle operation detection unit that detects whether or not the driver holds the handle with both hands. When the driver operation detection unit detects that at least one hand of the driver has detached from the steering wheel, the operation restriction during driving of the vehicle is not released and it is detected that both hands are holding the steering wheel. In some cases, the operation restriction can be released. As a result, the operation switch 4a can be operated by another occupant only in a state where the driver is forced to operate both hands and cannot perform other operations. For example, as shown in FIG. 4, when the vehicle is in a straight traveling state, it is provided on each of the left side and the right side of the handle 40, and when both release switches 4b are pressed simultaneously, It can be configured such that the operation restriction during traveling of the vehicle is released. In addition, the operation restriction can be automatically released when it is recognized by the image recognition device that the driver's hands are in contact with the steering wheel.

  As shown in FIG. 3, the start operation unit 5 is a key cylinder in which the key 50 is inserted into the key hole 55, and is operated by moving the inserted key 50 to a predetermined position. As shown in FIG. 5, the key inserted into the keyhole 55 can be rotated together with the key cylinder in a certain angular range around a horizontal line that coincides with the key insertion direction. From the rotation limit position on the left side), an OFF state position 5a, a position 5b for turning on the accessory power supply of the vehicle, a position 5c for turning on the ignition, and a position 5d for starting the engine at predetermined angular intervals. They are determined in this order, and a corresponding control signal is output at each angular position as the key rotates. Regarding the engine start position 5d, the key 50 automatically returns to the ignition ON position 5c when the hand is released.

  The main ECU 6 includes a CPU 61, a RAM 62 having a work memory 62a, etc., a ROM 63 for storing various programs, a bus line 64, an I / O 65, and an I / F 66, and via the I / F 66, a radio ECU 71, a CD player 72, It is connected to various control devices such as a cassette player 73, a navigation ECU 74, a telephone ECU 75, and a television ECU 76. The main ECU 6 receives display data from these control devices by a predetermined operation of the device operation unit 2 and displays it on the display unit 1a. In the present embodiment, the main ECU 6 executes a control program installed in the ROM 63, whereby the operation restriction means, the operation restriction release means (operation restriction release command means), the restriction release prohibition means (determination) in the present invention. Timing regulation means, operation restriction release determination means, release command prohibition means) and the like.

  The radio ECU 71 performs control for using radio functions such as demodulation and tuning of the reception channel. The TV ECU 76 performs control for using TV functions such as selection and tuning of reception channels, and also controls ON / OFF of output of TV reception signals to the display unit 1a. The telephone ECU 75 performs control for using the telephone function. The CD player 72 performs control such as reading a CD and outputting sound. The cassette player 73 performs cassette tape playback control. A well-known technique can be utilized for control of these various ECUs.

  In the present invention, as described above, an operation restriction (also referred to as driving compulsion) that restricts the driver's switch operation during traveling is provided, and when the vehicle is traveling, an operation restriction state in which the switch operation is restricted (running) (Also called forced mode). Further, the operation restriction during traveling can be released by operating the operation restriction release input unit (restriction release operation unit) 4, and the operation restriction during traveling is released from the engine stop state to the engine start. If this is the case, it can be detected as an abnormal state in which unauthorized modification has been made, and the release of forced running can be prohibited. FIG. 6 is a flowchart showing the flow of a program (running forced release function determination program) 63a that can prohibit the release of forced running for a vehicle that has been tampered with.

  The running forced release function determination program 63a in FIG. 6 generates an edge signal (determination timing regulation signal) when the accessory power supply is turned on when the key 50 inserted into the key cylinder 5 shown in FIG. 5 reaches the accessory position 5b. The CPU 61 is activated as an activation trigger. It should be noted that the start of the traveling forced release function determination program 63a is not necessarily triggered when the accessory position 5b of the key 50 is reached, but an edge signal output at another position can be used as a trigger. For example, a signal that is generated when the key 50 is inserted into the key hole 55 of the key cylinder 5, when the key reaches a position where the ignition is ON 5c, or when the key reaches the engine start position 5d is displayed as a forcible travel canceling function. It can also be used as a trigger signal for starting the determination program 63a. In addition, the start trigger of the traveling forced release function determination program 63a is not limited to the edge signal as described above. For example, a flag in a predetermined storage unit is set based on a predetermined process in the engine start sequence, and the CPU 61 Reading the set state can be used as a trigger.

  In S11 of the travel forcible release function determination program 63a, the travel forcible release flag is reset to “0” to enable the forcible release. As a result, even if the release of the forced driving is prohibited in the subsequent processing, it can be easily reset by restarting the engine as long as unauthorized modification of the vehicle is removed. In S12, based on the operation state of the operation restriction release input unit (restriction release operation unit) 4 immediately after the reset in S11, it is determined whether or not a forced traveling release command has been issued. In this embodiment, the determination is made based on whether or not the CPU 61 has detected a signal (release command) based on the pressing of the release switch 4a (FIG. 3). If there is no cancel command, the traveling forced cancel function determination program 63a is terminated, and if there is a cancel command, that is, if there is an illegal modification, the process proceeds to S13. In S13, upon detecting the abnormal state in S12, the travel forced release flag is set to “1”, and in S14, the display device 1 is used as an alarm output means, and “the travel forced release function is in an illegal state. Therefore, a warning message such as “Release function is stopped” or “Immediately modify unauthorized modification” is displayed on the display unit 1a, and the traveling forced release function determination program 63a is terminated. Note that these warnings are not limited to screen display by a display device, and are not particularly limited as long as they can at least notify or warn the driver, such as a warning by voice or lighting of a warning lamp. .

  Further, in the present invention, the forcible travel is executed based on the state of the travel forcible release flag by the travel forcible release function determination program 63a. FIG. 7 is a flowchart showing a flow of a travel forcing control program 63b for executing the travel forcing.

  In the travel forcing control program 63b of FIG. 7, first, in S31, it is detected by the vehicle speed sensor 3 whether or not the vehicle is traveling. When the vehicle is not traveling, the process proceeds to S36 to cancel the forced traveling, and the driver can operate the operation switch 2a. If the vehicle is traveling, the process proceeds to S32, where it is determined whether or not a command to cancel the traveling is issued based on the operation state of the release switch 4a. In the present embodiment, the CPU 61 determines whether or not a signal based on pressing of the release switch 4a (FIG. 3) is detected. If there is no release command, the process proceeds to S35, in which traveling forcing is set, and the operation of the predetermined operation switch 2a in the operation switch group 2 that should limit the operation during traveling is prohibited or invalidated. If there is a release command, the process proceeds to S33, where it is determined whether or not the travel forced release function flag is set. If the travel forced release function flag is “0”, the process proceeds to S36 and the travel forced is released. If the travel forcible release function flag is “1”, the process proceeds to S34, and an alarm is output such as displaying the above-mentioned warning text on the display unit 1a, and the process proceeds to S35 to execute the travel compulsion.

  As a result, even when the release switch 4a is pressed during traveling of the vehicle and the forcible driving should be released, the forcible release flag is set by the forcible release function determination program 63a made during the engine start process. If it is, driving | running | working forced cancellation | release is not cancelled | released and the switch operation of the operation switch group 2 restrict | limited beforehand during driving | operation cannot be performed. In order to cancel this, first, it is necessary to stop the engine once, modify the unauthorized modification, start the engine again, and execute the travel forcible release function determination program 63a. The operation restriction during traveling of the vehicle in this embodiment is a restriction on any one of the operation switch groups 2 provided in the display device 1, and an input operation of a function performed by these switch operations, for example, navigation It is possible to restrict the function map search, destination setting, telephone number input, switching operation to the TV screen, etc., but the operation subject to the operation restriction of the present invention is not limited to these, music CD selection operation, volume adjustment operation, etc. can be included. Further, the present invention can also be applied to a door lock by a button operation of a portable device carried by a user.

  Moreover, the traveling forced determination program 63a can be configured as shown in FIG. In FIG. 8, in S111, the CPU 61 determines whether or not the engine is started. If the engine is in an engine starting state, the traveling forced determination program 63a is repeated from the beginning. If the engine is not started, a determination signal for canceling the forced running is read in S112. A signal generated when the accessory position 5b of the key 50 is reached is used as the determination signal, and the CPU 61 reads the presence / absence of the determination signal based on the signal level held in the I / O. In S113, the presence / absence of the determination signal is determined. If there is no determination signal, the process proceeds to S118, the travel forcible release function flag is reset to “1”, and the travel restriction can be released. If there is a trigger signal, the process proceeds to S114, and it is determined whether or not a command for canceling traveling is issued based on the operating state of the release switch 4a. Specifically, the CPU 61 determines whether or not a signal (release command) based on pressing of the release switch 4a (FIG. 3) is detected.

  If there is a cancel command in S114, the process proceeds to S116, and the travel forcible cancel function flag is set to “0”. As a result, it becomes impossible to cancel the driving compulsion, and in S117, the same warning text and notification text as in the above-described embodiment are displayed on the display unit 1a, and then the program returns to the start of the driving compulsory determination program 63a. If there is no cancel command in S114, the process proceeds to S115, in which it is determined whether the forcible travel cancel function flag has already been set to "1". If it is already set to “1”, the process proceeds to S117. When the traveling forced release function flag is “0”, the traveling forced determination program 63a is repeatedly executed from the beginning. The same effect as in FIG. 6 can also be obtained by the forced running cancellation function determination program of FIG.

  As described above, the control device for the in-vehicle electronic device according to the present embodiment, while the vehicle is running, with respect to the predetermined limit operation unit (the driving force target operation unit) of the in-vehicle electronic device having the display unit, While the forced driving mode in which the operation input to the limited operation unit is restricted is set, the forced driving mode is canceled based on an operation on a separately provided restriction canceling operation unit (running forced canceling operation unit). Furthermore, a determination target operation that is inevitably executed by the user when starting the engine of the vehicle on which the vehicle-mounted electronic device is mounted is determined in advance, and the travel forcible release operation unit is provided when the determination target operation is executed. When an operation state that supports the release of the travel forced mode setting is entered, it is possible to prohibit the release of the travel forced mode.

  The running forced release function determination program 63a is executed not only at the time of engine start by the engine start method by key operation but also at the time of engine start by an engine start method called a smart and push start system that does not use a key. Also good. In this case, for example, the starting process is executed according to the flow shown in FIG. In this case, the display control mechanism 100 of FIG. 1 is added with a known configuration that is connected to an immobilizer control unit, a steering lock control unit, and the like.

  In the case of FIG. 9, first in S51, in the immobilizer control unit, the user authentication ID sent from the wireless communication portable device (smart key) carried when the occupant approaches within the predetermined range of the vehicle, and the non-volatile that the immobilizer control unit has The master ID stored in the memory. In S52, the read IDs are collated, and in S53, it is determined whether or not these IDs match as a result of the collation. If they match, the process proceeds to S54, and if they do not match, the process returns to S51. In S54, a collation coincidence signal is output to the aforementioned main ECU 6 in S53. The main ECU 6 uses this as a trigger to start the above-described forced running release function determination program 63a of FIG. Thereby, it is determined whether or not the forcible release is invalidated. Thereafter, in S55, the steering lock control unit releases the steering lock, and in S56, the immobilizer is unset to cancel the engine operation prohibition state. Thereafter, the brake pedal is depressed in S57, and in this state, the engine is started by pressing the push switch for starting the engine.

  Note that, in the engine start method referred to as this smart and push start system, the timing for executing the travel forcible release function determination program 63a does not have to be triggered by the ID collation match as described above. A predetermined step before starting the engine may be used as a trigger. For example, it can be triggered by ID authentication, steering unlock, immobilizer unset (when the engine operation prohibition state is released), brake pedal depression, engine start push switch press, or the like.

  Further, in the present invention, the engine start is not necessarily required for the execution of the determination process of whether or not the forced driving can be canceled (in this embodiment, by the execution of the forced driving cancellation function determination program 63a). It is only necessary to execute the process or operation as a trigger at least in the course of starting the engine. For example, when the determination process is executed when the key 50 reaches the accessory position 5b, a restriction is imposed on the operation of the navigation device when the engine is stopped, and the restriction on unauthorized driving is released. Even if the vehicle is not traveling, the operation of the limited operation unit may be invalidated.

  As mentioned above, although the Example of this invention was described, these are only illustrations, this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. .
