Description

Vehicle control device

  The present invention relates to a vehicle control device that can also use a door knob for opening a door provided in a vehicle as an operation means for receiving an operation from a vehicle user.

  In recent vehicle control devices, a person who is about to get on (or get off) pushes a switch provided near the door knob instead of pulling the door knob in the direction of opening the door provided on the vehicle. Some automatically open the door. In addition, a device has been proposed in which a vein authentication device is incorporated in the door knob and the door is unlocked if the finger vein patterns match. As described above, the door knob functions not only as a handle for a person to pull the door, but also as an input means for receiving an input operation or data input from the person to the vehicle.

In addition, some vehicle control devices have some in-vehicle devices and in-vehicle functions that are provided to a vehicle user outside the vehicle by operating a remote control for remote control without opening the door of the vehicle. There is something to do. For example, when a button of a remote control remote control provided on a vehicle key is pressed, the vehicle is opened and closed (Patent Document 1).
JP 2002-54331 A

  However, the vehicle control device of Patent Document 1 must hold a remote control for exclusive use for remote operation in order for a vehicle user outside the vehicle to execute some in-vehicle devices and in-vehicle functions provided in the vehicle. . As long as the number of in-vehicle devices and in-vehicle functions to be executed is small, the remote control remote control may have a simple structure, so that the vehicle user feels resistance to carrying the small remote control remote control attached to the key. Although it does not have so much, it is assumed that it has a sense of resistance to carrying a remote control remote control that increases in size as the number of in-vehicle devices and in-vehicle functions to be executed increases.

  The present invention has been made in view of the above circumstances, and by using a door knob provided on a door as an input means, a wide variety of in-vehicle devices provided to the vehicle from outside the vehicle without opening the vehicle door. An object of the present invention is to provide a vehicle control device that can execute an in-vehicle function.

The vehicle control device of the present invention includes a door knob that moves in a direction to open a door provided in the vehicle, a strain sensor that is provided in contact with a part of the door knob, and a control that controls various in-vehicle devices mounted in the vehicle. A first threshold value that is regarded as having moved the door knob to open the door, out of a voltage waveform output from the strain sensor, and a first threshold value in the previous period A rhythm input analysis unit that generates an input pattern based on the presence or absence of a peak voltage included between a small second threshold and identifies at least one in-vehicle device among the various in-vehicle devices according to the input pattern The control unit controls the in-vehicle device specified by the rhythm input analysis unit.

According to this configuration, by using the door knob provided on the door as an input means, it is possible to execute various in-vehicle devices and in-vehicle functions provided in the vehicle from outside the vehicle without opening the door of the vehicle. it can. Furthermore, it is possible to prevent the vehicle control device from creating an input pattern due to the extremely small movement of the door knob caused by the vehicle itself shaking.

  The vehicle control device of the present invention estimates the presence or absence of the peak voltage according to whether or not the period during which the voltage waveform exceeds the second threshold is less than a predetermined time interval.

  According to this configuration, from the movement of the doorknob, the intention of the vehicle user (operation of the doorknob to open the door, or operation of the doorknob to execute a certain in-vehicle device or a certain in-vehicle function provided in the vehicle from outside the vehicle. ) Can be accurately determined. That is, it is possible to prevent erroneously determining that the door knob has been pulled to open the door as an input for operating the vehicle.

  According to the vehicle control device of the present invention, by using a door knob provided on the door as an input means, a variety of in-vehicle devices and in-vehicle functions provided in the vehicle from outside the vehicle can be provided without opening the door of the vehicle. Can be executed.

Hereinafter, a vehicle control device according to an embodiment of the present invention will be described in detail. FIG. 1A shows an outline of operations performed by a vehicle user on the door knob 101 in the vehicle control apparatus according to the embodiment of the present invention. FIG. 1B shows the vehicle control apparatus according to the embodiment of the present invention. The schematic diagram when the operation which a vehicle user performs with respect to the doorknob 101 is seen from another direction is shown, respectively.
In the vehicle control apparatus according to the embodiment of the present invention, the door knob 101 provided on the door plate 110 constituting a part of the outer surface of the vehicle is hit by the vehicle user ("(the vehicle user) hits the door knob"). 1 includes the case where the door knob is pushed downward from the vertical direction of the door knob 101 as shown in FIG. 1 and the case where the door knob 101 is pushed toward the door plate 110). The strain sensor 102 that vibrates (hereinafter, the strain sensor 102 vibrates with the movement of the door knob 101 is expressed as “the strain sensor 102 vibrates” or “the vibration of the strain sensor 102”. (The expression includes that the strain sensor 102 is deformed in accordance with the movement of the door knob 101). The detected voltage waveform is converted into a pulse signal by the waveform shaping circuit 103, and a certain in-vehicle device among various in-vehicle devices mounted on the vehicle is specified based on the pulse signal, and processing by the in-vehicle device is controlled. is there. Thereby, the vehicle user can execute various vehicle-mounted devices and vehicle-mounted functions provided in the vehicle while staying outside the vehicle. The important point in the vehicle control apparatus according to the embodiment of the present invention is that the vehicle user first pulls the door knob to open the door, or the vehicle-mounted device and the vehicle-mounted function provided in the vehicle are executed. It is how to determine from the voltage waveform detected by the strain sensor 102 whether the door knob has been hit.

  Hereinafter, the configuration for realizing the process of determining the movement of the doorknob in the vehicle control device of the present invention will be described in detail.

  FIG. 2 shows a block diagram of the vehicle control apparatus according to the embodiment of the present invention. The vehicle control apparatus according to the embodiment of the present invention includes a door knob mechanism 1, a control unit 2, a window opening / closing control unit 3, and a door lock opening / closing control unit 4. In FIG. 2, when the vehicle user moves the door knob mechanism 1 (for example, hits the door knob) with the intention of the vehicle operation to open and close the window provided on the door, the control unit 2 determines that In response to the control signal, the window opening / closing control unit 3 controls to automatically open / close the window. On the other hand, when the vehicle user pulls the door knob mechanism 1 to open the door, the control unit 2 determines that It is assumed that the door lock opening / closing control unit 4 receiving the control signal releases the lock applied to the door and permits the vehicle user to open the door. In addition, although opening / closing of the window by the window opening / closing control part 3 was mentioned as an example of the vehicle operation | movement performed by a vehicle, it is not restricted to this (For example, refer vehicle operation in FIG. 8 mentioned later). Further, although not essential to the vehicle control device of the present invention, a function of performing wireless authentication with a wireless communication unit (key) existing at a certain distance and releasing the door lock when the authentication is successful. When the control unit 2 determines that the authentication has been successful and the vehicle user has pulled the door knob mechanism 1 to open the door, the door lock is opened and closed. By causing the control unit 4 to release the door lock, the vehicle control apparatus according to the embodiment of the present invention releases the door lock only when the vehicle user is about to get into the vehicle. However, it is possible to prevent the door lock from being released simply by approaching the vehicle without intending to release the door lock, and to improve theft prevention.

  Next, the structure of the door knob mechanism 1 will be described with reference to the structure of the door knob in the vehicle control apparatus according to the embodiment of the present invention shown in FIG. The door knob mechanism 1 in the vehicle control apparatus according to the embodiment of the present invention includes a door knob 101, a strain sensor 102, a waveform shaping circuit 103, a rotary bearing 104, a ring spring 105, rubber 106, a sensor holding plate spring 107, an adhesive 108, and The wiring 109 is configured. In FIG. 3, the door knob 101 rotates in the direction specified by the rotary bearing 104. Further, a part of the door knob 101 passes through the door plate 110 constituting the outer surface of the door and is in contact with the sensor holding plate spring 107, and the vicinity of the through portion in the door knob 101 is elastic from the ring spring 105 and the rubber 106. Therefore, elasticity corresponding to the rotation of the door knob 101 is given to the vehicle user. In addition, when no external force is applied to the door knob 101 (neutral state), the door knob 101 is separated from the door plate 110, and the strain sensor 102 can easily detect vibration. Further, the strain sensor 102 is fixed to the sensor holding base plate spring 107 by an adhesive 108 attached to two positions on both ends of the sensor holding base plate spring 107. The strain sensor 102 vibrates with the vibration or movement of the sensor holding base plate spring 107 when the door knob 101 rotates. The waveform shaping circuit 103 electrically detects vibration by the strain sensor 102, converts the detected electric signal into a pulse signal, and outputs the pulse signal to the control unit 2 via the wiring 109. Note that the door knob mechanism 1 of the present invention enables the door plate 110 even if the rotation direction of the door knob 101 rotates away from the door plate 110 (the direction in which the vehicle user pulls the door knob) thanks to the ring spring 105 and the rubber 106. The strain sensor 102 can be vibrated even if it rotates in a direction approaching (a direction in which the vehicle user pushes the door knob).

  Next, based on the electrical signal output from the strain sensor 102, the vehicle user intends to open the door, whether the vehicle user intends to perform the vehicle operation by operating the vehicle or the door knob 101. Whether the door knob 101 has been moved will be described by the control unit 2. FIG. 4 shows an example of a voltage waveform output to the control unit of the vehicle control apparatus according to the embodiment of the present invention.

  The electrical signal output from the strain sensor 102 by one movement of the door knob 101 has a waveform having one peak value with the maximum value when the movement of the door knob 101 is maximum, as in the voltage waveform shown in FIG. . The control unit 2 determines whether the peak value is within a numerical range specified by two threshold values (the voltage threshold value 1 and the voltage threshold value 2 in FIG. 4). The movement of the door knob 101 intended to execute (opening and closing the window) (for example, hitting the door knob), or the movement of the door knob 101 intended for the vehicle user to open the door (for example, pulling the door knob). Is determined. The voltage threshold value 1 is a minimum necessary voltage value to be input to the control unit 2 in order to determine that the movement of the door knob 101 intended for the vehicle user to open the door (the voltage threshold value 1 is the door knob quotation threshold value). The voltage threshold value 2 is a minimum necessary value to be input to the control unit 2 in order to determine that the vehicle user is moving the door knob 101 intended to execute the vehicle operation by the vehicle operation. It is a voltage value (the voltage threshold value 2 may be called the threshold value for vehicle operation). In the vehicle control apparatus according to the embodiment of the present invention, the vehicle user controls whether the door is opened or the vehicle operation is executed according to the movement of the door knob. Note that the doorknob quotation threshold is greater than the vehicle operation threshold.

  When the electrical signal having a certain waveform is output from the strain sensor 102, the control unit 2 specifies the peak value of the voltage waveform, and “1. Door knob quote threshold value or more”, “2. Vehicle operation threshold value or more and door knob quote value”. It is determined whether it falls under “less than threshold value” or “3. less than vehicle operation threshold value”. If the control unit 2 determines that “1. More than the doorknob reference threshold” (voltage waveform at the time of “doorknob pull” in FIG. 4), the control signal for unlocking the door is sent to the door lock opening / closing control unit 4. When the output is released to release the lock, and it is determined that “2. The vehicle operation threshold is greater than or equal to the doorknob reference threshold” (voltage waveform during “vehicle operation” in FIG. 4), the control signal for opening the window is displayed. If it is output to the opening / closing control unit 3 to open the window and it is determined that “3. Less than vehicle operation threshold” (voltage waveform at the time of “body shake” in FIG. 4), the electric signal from the doorknob mechanism 1 again Wait for output. When the electrical signal output from the door knob mechanism 1 is “3. Less than the threshold value for vehicle operation” (that is, when the vibration of the door knob 101 is small), it is not the vibration of the door knob 101 caused by human operation, It is assumed that the door knob 101 vibrates due to, for example, the vehicle itself shaking when the truck passes through the vehicle. The vehicle operation threshold is useful in order to prevent the vehicle control apparatus from operating the vehicle due to such vibration of the door knob 101.

  Although the processing by the control unit 2 is conceptually described so as to be discriminated by the peak value of the voltage waveform itself output from the strain sensor 102, the voltage waveform shaped by the waveform shaping circuit 103 of the doorknob mechanism 1 is transferred to the control unit 2. Output is also assumed. The waveform shaping circuit 103 generates a pulse signal for generating an amplitude when the voltage value is equal to or higher than the voltage threshold 2 (vehicle operation threshold), and shapes the voltage waveform output from the strain sensor 102 at the time of “doorknob pull”. When this is done, the waveform shaping signal at the time of “door knob pull” is outputted to the control unit 2, and when the voltage waveform at the time of “vehicle operation” is shaped, the waveform shaping signal at the time of “vehicle operation” is outputted to the control unit 2. When a certain pulse signal is output from the waveform shaping circuit 103, the control unit 2 specifies the pulse time interval of the pulse signal, and either “1. Time threshold 1 or more” or “2. Time threshold 1 or less” is selected. It is determined whether it corresponds to. If the control unit 2 determines that “1. The time threshold value is 1 or more” (the waveform shaping signal at the time of “door knob pull” in FIG. 4), the control signal for unlocking the door is sent to the door lock opening / closing control unit 4. To release the lock and determine that “2. Time threshold value is less than 1” (waveform shaping signal at the time of “vehicle operation” in FIG. 4), a control signal for opening the window is displayed. To open the window. In this way, the determination may be made using the characteristics of the voltage waveform output from the strain sensor 102 during “doorknob pull” or “vehicle operation”.

  By the processing by the control unit 2 as described above, the vehicle control device according to the embodiment of the present invention is the movement of the door knob 101 intended to cause the vehicle user to execute the vehicle operation. It can be determined whether the movement of the door knob 101 intended to open the door.

  By the way, the vehicle control device can execute only one vehicle-mounted device and vehicle-mounted function only by discrimination based on the peak value of the voltage waveform output from the door knob mechanism 1 as described above by the control unit 2. Here, the vehicle control device according to the embodiment of the present invention specifies a plurality of in-vehicle devices mounted on the vehicle, an in-vehicle device intended to be executed by a vehicle user from among the in-vehicle functions, and the in-vehicle functions from the input pattern. How to do will be described. FIG. 5, FIG. 6 and FIG. 7 show examples of voltage waveforms output to the control unit of the vehicle control device according to the embodiment of the present invention.

  The control unit 2 is the movement of the door knob 101 intended to cause the vehicle user to execute the vehicle operation by the vehicle operation from the waveform (voltage waveform 1 in FIG. 5) output from the door knob mechanism 1 by the processing described above. If it discriminate | determines, the input pattern "1" which makes the first digit expressed by a binary number 1 will be produced, and time measurement will be started from the time of the discrimination. The control unit 2 detects the vehicle user from the next waveform (voltage waveform 2 in FIG. 5) output from the doorknob mechanism 1 within a predetermined time interval (time threshold 2 in FIG. 5) after starting the time measurement. When it is determined that the movement of the doorknob 101 intended to execute the vehicle operation by the vehicle operation, the input pattern “11” having the next digit expressed in binary number as 1 is created, and the time of the determination Start timing again.

  On the other hand, the control unit 2 creates the input pattern “1” and starts counting from the determined time point, and within a predetermined time interval (time threshold value 2 in FIG. 6), the vehicle user operates the vehicle. When the doorknob mechanism 1 does not accept the movement of the doorknob 101 intended to execute the vehicle operation, an input pattern “01” in which the next digit (second digit) expressed in binary is set to 0 is created. Thereafter, when the control unit 2 determines that the movement of the door knob 101 is intended to cause the vehicle user to execute the vehicle operation by operating the vehicle from the waveform (voltage waveform 3 in FIG. 6) output from the door knob mechanism 1, An input pattern “101” is created with the third digit represented by a binary number as 1, and time measurement is started from the point of determination.

  The controller 2 continues to generate an input pattern that is an intermittent signal composed of “0” and “1” while increasing the number of digits in the same manner, and the input pattern reaches a predetermined number of digits. As shown in FIG. 7, when the door knob mechanism 1 does not accept the movement of the door knob 101 for a predetermined time interval (time threshold 2) and the predetermined time interval (time threshold 3) elapses, the input pattern is changed. The generation is terminated, and the generated input pattern is compared with an already registered input pattern. FIG. 8 shows a correspondence list between registered input pattern examples and vehicle operation examples in the vehicle control apparatus according to the embodiment of the present invention. In FIG. 8, the registered input patterns are registered as “●” for a single sound of the name of an in-vehicle device that is a vehicle operation target, and “−” for a long sound (“−”) or a prompt sound (“tsu”). (“●” and “−” in FIG. 8 correspond to the above-described binary numbers “1” and “0”, respectively). By registering in this way, the vehicle user can easily learn the correspondence between the input pattern and the in-vehicle device that is the vehicle operation target when the input pattern is input. The control unit 2 compares the input pattern being generated with the already registered input pattern, and if they match, executes the vehicle operation corresponding to the input pattern. In addition, regarding the user input intention “assistant”, after the vehicle operation analysis / judgment state described later, the passenger side door is not unlocked immediately, but within a certain time after the user input intention “assistant” is input. When detected, the passenger side door unlocking may be performed together with the driver side door unlocking. Thereby, it is possible to reduce the possibility that a suspicious person enters from the passenger seat side, and to improve the security. When the user input intention is “assistant”, only the driver's seat side is unlocked in the normal door knob pull.

  In addition, during the input pattern generation | occurrence | production by the control part 2, it is also assumed that the vehicle user can move the door knob 101 to open a door. In this case, the control unit 2 ends the generation of the input pattern when it is determined that the movement of the door knob 101 intended to open the door by the vehicle user, and the generated input pattern and the already registered input pattern are terminated. Or a plurality of in-vehicle devices mounted on the vehicle, the in-vehicle device that the vehicle user intends to execute from among the in-vehicle functions, and the process itself that identifies the in-vehicle function is stopped. Also good.

  By the processing by the control unit 2 described above, the vehicle control device according to the embodiment of the present invention includes a plurality of in-vehicle devices mounted on the vehicle, an in-vehicle device intended to be executed by a vehicle user from among in-vehicle functions, and in-vehicle. Since the function can be specified from the input pattern, a wide variety of in-vehicle devices and in-vehicle functions provided in the vehicle can be executed from outside the vehicle without opening the door of the vehicle. Hereinafter, a series of processing contents by the control unit 2 will be described in three cases (from the first embodiment to the third embodiment).

(First embodiment)
One example of vehicle control by the vehicle control device of the first embodiment of the present invention will be described with reference to a transition diagram of vehicle control states by the vehicle control device of the first embodiment of the present invention shown in FIG.
It is assumed that the vehicle locks the door before the door knob mechanism 1 receives the operation of the door knob 101 by the vehicle user (door lock state). The control unit 2 is notified of a successful authentication (that is, that the vehicle user is approaching) from a wireless authentication device that performs wireless authentication with the wireless communication unit (key) owned by the vehicle user. Then, the door knob pull / vehicle operation determination for determining whether the peak value of the voltage waveform output from the door knob mechanism 1 corresponds to “1. More than door knob quote threshold” or “2. Less than door knob quote threshold”. Transition to the state.

  If the control unit 2 determines that the door knob reference threshold value is exceeded, the control unit 2 outputs a control signal for unlocking the door to the door lock opening / closing control unit 4 to release the lock (door unlock state). Thereafter, the control unit 2 returns to the door lock state when an operation for closing the door lock is performed.

  On the other hand, if the control unit 2 determines that it is less than the doorknob quoting threshold value, it starts creating an input pattern, and thereafter, every time a voltage waveform is output from the doorknob mechanism 1, the peak of the voltage waveform output from the doorknob mechanism 1 is reached. It is determined whether the value corresponds to “1. More than door knob quote threshold” or “2. Less than door knob quote threshold”. The control unit 2 determines that it is less than the doorknob quotation threshold within a predetermined time interval (time threshold 2) from the previous determination time, or the doorknob within a predetermined time interval (time threshold 2) from the previous determination time. The number of digits of the binary input pattern is increased according to the fact that the output is not accepted from the mechanism 1. After completing the creation of the input pattern, the control unit 2 makes a transition to the vehicle operation analysis / determination state in which the created input pattern is compared with the already registered input pattern. When the control unit 2 in the vehicle operation analysis / determination state determines that the generated input pattern matches, for example, the input pattern corresponding to the vehicle operation “open window” shown in FIG. 8, a control signal for opening the window is displayed. Output to the opening / closing control unit 3 to open the window. Thereafter, when the control unit 2 receives a control signal from the window opening / closing control unit 3 notifying that the window opening has been completed, the control unit 2 returns to the door lock state. The control unit 2 also returns to the door lock state when there is no input pattern that matches the generated input pattern.

  According to the vehicle control apparatus of the first embodiment of the present invention, by using a doorknob provided on the door as an input means, a wide variety of in-vehicle devices provided to the vehicle from outside the vehicle without opening the door of the vehicle. The device and the in-vehicle function can be executed. In addition, the user's intention (operation of the doorknob for opening the door, or operation of the onboard device provided to the vehicle from the outside of the vehicle, operation of the doorknob for executing an onboard function) is accurately determined from the movement of the doorknob. It can be determined accurately. Further, when the doorknob pull is detected, the vehicle operation analysis / determination state is not shifted.

(Second Embodiment)
One example of vehicle control by the vehicle control device of the second embodiment of the present invention will be described with reference to a transition diagram of vehicle control states by the vehicle control device of the second embodiment of the present invention shown in FIG.
It is assumed that the vehicle locks the door before the door knob mechanism 1 receives the operation of the door knob 101 by the vehicle user (door lock state). The control unit 2 is notified of a successful authentication (that is, that the vehicle user is approaching) from a wireless authentication device that performs wireless authentication with the wireless communication unit (key) owned by the vehicle user. Then, the peak value of the voltage waveform output from the doorknob mechanism 1 is “1. More than the doorknob quote threshold”, “2. More than the vehicle operation threshold and less than the doorknob quote threshold”, “3. Less than the vehicle operation threshold ”Transitions to a doorknob pull / vehicle operation discrimination state for discriminating one of the above.

  If the control unit 2 determines that the door knob reference threshold value is exceeded, the control unit 2 outputs a control signal for unlocking the door to the door lock opening / closing control unit 4 to release the lock (door unlock state). Thereafter, the control unit 2 returns to the door lock state when an operation for closing the door lock is performed.

  If the control unit 2 determines that the vehicle operation threshold is less than the threshold value, the control unit 2 maintains the door knob pull / vehicle operation determination state and waits for the next voltage waveform output from the door knob mechanism 1.

  Further, if the control unit 2 determines that the vehicle operation threshold value is greater than or equal to the vehicle operation threshold value and less than the door knob reference threshold value, the control unit 2 starts to create an input pattern. Whether the peak value of the voltage waveform to be applied falls under one of “1. Door knob quotation threshold or higher”, “2. Vehicle operation threshold or higher and less than door knob quotation threshold”, or “3. Vehicle operation threshold lower than” Determine. The control unit 2 determines that the vehicle operation threshold is not less than the vehicle operation threshold and is less than the doorknob quoting threshold within a predetermined time interval (time threshold 2) from the previous determination, or the predetermined time interval (time) from the previous determination The number of digits of the binary input pattern is increased in accordance with the determination that the threshold value 2) is less than the vehicle operation threshold value. After completing the creation of the input pattern, the control unit 2 makes a transition to the vehicle operation analysis / determination state in which the created input pattern is compared with the already registered input pattern. When the control unit 2 in the vehicle operation analysis / determination state determines that the generated input pattern matches, for example, the input pattern corresponding to the vehicle operation “open window” shown in FIG. 8, a control signal for opening the window is displayed. Output to the opening / closing control unit 3 to open the window. Thereafter, when the control unit 2 receives a control signal from the window opening / closing control unit 3 notifying that the window opening has been completed, the control unit 2 returns to the door lock state. The control unit 2 also returns to the door lock state when there is no input pattern that matches the generated input pattern.

  According to the vehicle control apparatus of the second embodiment of the present invention, by using a door knob provided on the door as an input means, a wide variety of on-vehicle equipment provided to the vehicle from outside the vehicle without opening the door of the vehicle. The device and the in-vehicle function can be executed. In addition, the user's intention (operation of the doorknob for opening the door, or operation of the onboard device provided to the vehicle from the outside of the vehicle, operation of the doorknob for executing an onboard function) is accurately determined from the movement of the doorknob. It can be determined accurately. In addition, it is possible to prevent the vehicle control device from creating an input pattern due to a very small movement of the door knob due to the vehicle itself shaking. Further, when the doorknob pull is detected, the vehicle operation analysis / determination state is not shifted. In addition, since the voltage waveform at the time of pulling the door knob exceeds the voltage threshold value 1 and the voltage threshold value 2, if the door unlock state by the door knob pull detection is not distinguished from the vehicle operation analysis / judgment state, the door knob is pulled twice. Even if it is recognized that the pulse generated by the first doorknob pull is equal to or greater than the doorknob quotation threshold, there is a possibility that the vehicle operation analysis is started and the vehicle operation analysis / determination state is entered. When the doorknob pull is detected, the state transition is configured so as not to shift to the vehicle operation analysis / judgment state. For example, even if the doorknob is pulled twice, the input pattern (●● ) Is prevented from shifting to the window control state.

(Third embodiment)
One example of vehicle control by the vehicle control device of the third embodiment of the present invention will be described with reference to the transition diagram of the vehicle control state by the vehicle control device of the third embodiment of the present invention shown in FIG.
It is assumed that the vehicle locks the door before the door knob mechanism 1 receives the operation of the door knob 101 by the vehicle user (door lock state). The control unit 2 is notified of a successful authentication (that is, that the vehicle user is approaching) from a wireless authentication device that performs wireless authentication with the wireless communication unit (key) owned by the vehicle user. Then, in the pulse signal having a waveform shaped to be output from the doorknob mechanism 1, whether the pulse time interval corresponds to “1. Time threshold 1 or more” or “2. Less than time threshold 1”. Transition to the doorknob pull / vehicle operation determination state to be determined.

  If it is determined that the time threshold is 1 or more, the control unit 2 outputs a control signal for unlocking the door to the door lock opening / closing control unit 4 to release the lock (door unlock state). Thereafter, the control unit 2 returns to the door lock state when an operation for closing the door lock is performed.

  On the other hand, if the control unit 2 determines that the time threshold value is less than 1, the control unit 2 starts to create an input pattern. Thereafter, every time a voltage waveform is output from the doorknob mechanism 1, the above-described pulse time interval is “1. Which one of “1 or more” and “2. Less than 1 time threshold value” is determined. The control unit 2 determines that the time is less than the time threshold 1 within a predetermined time interval (time threshold 2) from the previous determination time, or the door knob within a predetermined time interval (time threshold 2) from the previous determination time. The number of digits of the binary input pattern is increased according to the fact that no output is received from the mechanism 1. After completing the creation of the input pattern, the control unit 2 makes a transition to the vehicle operation analysis / determination state in which the created input pattern is compared with the already registered input pattern. When the control unit 2 in the vehicle operation analysis / determination state determines that the generated input pattern matches, for example, the input pattern corresponding to the vehicle operation “open window” shown in FIG. 8, a control signal for opening the window is displayed. Output to the opening / closing control unit 3 to open the window. Thereafter, when the control unit 2 receives a control signal from the window opening / closing control unit 3 notifying that the window opening has been completed, the control unit 2 returns to the door lock state. The control unit 2 also returns to the door lock state when there is no input pattern that matches the generated input pattern.

  According to the vehicle control apparatus of the third embodiment of the present invention, by using a door knob provided on the door as an input means, a wide variety of in-vehicle devices provided to the vehicle from outside the vehicle without opening the vehicle door. The device and the in-vehicle function can be executed. In addition, the user's intention (operation of the doorknob for opening the door, or operation of the onboard device provided to the vehicle from the outside of the vehicle, operation of the doorknob for executing an onboard function) is accurately determined from the movement of the doorknob. It can be determined accurately. Further, when the doorknob pull is detected, the vehicle operation analysis / determination state is not shifted.

  According to the vehicle control device of the present invention, it is possible to execute various vehicle-mounted devices and vehicle-mounted functions provided in the vehicle from the outside of the vehicle without opening the vehicle door. The door knob is useful in the field of vehicle control devices that can also be used as an operation means for receiving an operation from a vehicle user.
