Description

  The present invention relates to a vehicle setting device that performs various settings for a vehicle.

  When a plurality of drivers drive one vehicle, it is necessary to readjust the positions of the mirror and the seat each time the driver changes. Therefore, based on the image of the driver's face, it is determined whether or not the face is a registered driver's face. If the face is a registered driver's face, the mirror or seat is selected according to the driver. An apparatus for setting a position has been proposed (for example, see Patent Document 1).

Embodiments to which the present invention is applied will be described below with reference to the drawings.
[1. First Embodiment]
[1-1. Constitution]
A windshield 5 is mounted in front of the passenger compartment 3 of the vehicle 1 shown in FIG. A handle 9 is provided on the dashboard 7 below the windshield 5 so that the position of the handle 9 can be adjusted. Further, a head-up display 13 (see FIG. 2) for projecting various images onto the display area 11 set on the windshield 5 is provided inside the dashboard 7. In addition, the dashboard 7 is provided with an eye tracker 15 and a start switch 17 on the surface facing the driver D.

  The eye tracker 15 detects the posture of the eyeball of the driver D by applying infrared IR to the eyes of the driver D and detects the reflected light, and detects the direction of the line of sight E of the driver D based on the detected eye. The start switch 17 is provided around the handle 9 (for example, adjacent to the right) at a position where the driver D can easily operate.

  As shown in the block diagram of FIG. 2, the vehicle setting device mounted on the vehicle 1 includes the head-up display 13, the eye tracker 15, the start switch 17, the control ECU 20, the electric seat 21, and the electric mirror 23. , A handle adjustment device 25 and a shift position sensor 27 are provided. The control ECU 20 is constituted by a microcomputer centered on a CPU, ROM, and RAM.

  The electric seat 21 is a seat on which the driver D is seated, and is a well-known one provided with various electric actuators that move the seating position back and forth and adjust the angle of the backrest. Hereinafter, the seating position and the backrest angle are collectively referred to as a seating position. The electric mirror 23 is composed of a rearview mirror provided in the passenger compartment 3 and a side mirror provided outside the passenger compartment 3, and the angle of each reflecting surface is configured to be adjustable in various directions by an electric actuator. Yes. Hereinafter, when it is not necessary to distinguish between the rearview mirror and the side mirror, they are simply referred to as mirrors, and the angles of their reflecting surfaces are referred to as mirror positions. The handle adjusting device 25 includes an electric actuator that adjusts an angle of the handle 9 (hereinafter referred to as a handle position) around a horizontal axis. The shift position sensor 27 is a known sensor that detects a shift position (shift range) of the vehicle 1 that is switched by a shift lever or a shift switch (not shown).

[1-2. processing]
[1-2-1. Vehicle setting process at start-up]
Next, the starting vehicle setting process executed by the control ECU 20 will be described with reference to the flowchart of FIG. This process is executed by the CPU of the control ECU 20 based on a program stored in the ROM of the control ECU 20 when the power of the vehicle 1 is turned on (when the accessory switch is turned on for an internal combustion locomotive). The

  As shown in FIG. 3, in this process, first, in S10 (S represents a step: the same applies hereinafter), an authentication code input screen is displayed in the display area 11 of the windshield 5 by the head-up display 13 (HUD). Is displayed. FIG. 4A shows an example of the authentication code input screen. This authentication code input screen includes four substantially square display portions 11A, 11B, 11C, and 11D, and numbers “1” to “4” are displayed at the centers of the display portions 11A to 11D. When such an authentication code input screen is displayed in the display area 11, the driver D inputs the authentication code registered in advance in the control ECU 20 by the line of sight E. For example, when the authentication code of the driver D is “1234”, the driver D indicates his / her line of sight E in the order of display unit 11A → display unit 11B → display unit 11C → display unit 11D in FIG. Move as shown in.

  Therefore, in S20 following S10, the authentication code input by the driver D by the line of sight E is detected by detecting how the line of sight E has moved on the display units 11A to 11D via the eye tracker 15. The In subsequent S30, it is determined whether or not the authentication code detected in S20 matches the authentication code (information) registered in the control ECU 20 in advance. If they match (S30: Y), the process proceeds to S40. To do.

  In S40, the authentication code input screen displayed in the display area 11 is deleted (cancelled). In subsequent S50, automatic adjustment is made to the seat position, mirror position, and handle position registered in advance in the control ECU 20 in association with the authentication code, and the process ends. That is, in the control ECU 20, an authentication code, a seat position, a mirror position, and a handle position are registered in a one-to-one correspondence. In S50, the seat position, the mirror position, and the handle position corresponding to the authentication code detected in S20 are read, and the electric seat 21, the electric mirror 23, and the handle adjustment device 25 are driven accordingly. Thus, the seat position, the mirror position, and the handle position are automatically adjusted to positions corresponding to the driver D, respectively.

  In addition, when a plurality of authentication codes and a seat position, a mirror position, and a handle position corresponding to each authentication code are registered on the control ECU 20 in a one-to-one correspondence, the seat position and the like are input authentications. It is automatically adjusted to the position corresponding to the code. In that case, even when a plurality of drivers D drive one vehicle 1, the seat position, the mirror position, and the handle position are automatically adjusted to positions corresponding to the drivers D, respectively.

  On the other hand, if the authentication code detected in S20 does not match the pre-registered authentication code (S30: N), the process proceeds to S60, and the second time after the start of this process is that the above-mentioned mismatched. It is determined whether it is within the range. If it is within the second time (S60: Y), after the re-input of the authentication code is instructed to the driver D via the head-up display 13 in S70, the process proceeds to S10 described above. Thus, when the authentication code is re-input, if the authentication code detected in S20 is registered next (S30: Y), the process proceeds to S40 described above.

  In S60, when it is determined that the mismatch does not occur for the third time after the start of the process (S60: N), the process proceeds to S80. In S80, the authentication code input screen displayed in the display area 11 is erased (released) as in S40, and the process ends. In addition, even when the present process is completed without automatically adjusting the seat position, the mirror position, and the handle position in this way, these positions can be adjusted manually by the driver D. This manual operation may be an operation in which the driver D mechanically moves the mirror or the like directly by hand, or an operation in which the driver D operates a switch or the like to move the mirror or the like via an electric actuator or the like. Good.

  When this process ends, the driver D changes the shift position to the D range or the R range and moves the vehicle 1. In addition, this process is in the middle of the process when another process using the head-up display 13 is started, for example, when the shift position detected via the shift position sensor 27 changes to the D range or the R range. Or it may be forcibly terminated. However, also in this case, if the driving of the electric seat 21 or the like by S50 has already been started, it is desirable that the present processing is terminated after the automatic adjustment by the driving is completed.

[1-2-2. Vehicle setting process after startup]
Further, after the vehicle 1 starts moving, the control ECU 20 executes a post-startup vehicle setting process shown in FIG. 5 at a predetermined timing. This process is also executed by the CPU of the control ECU 20 based on a program stored in the ROM of the control ECU 20.

  Note that this process differs from the above-described start-time vehicle setting process in that S15 is inserted between S10 and S20, and that S15 is inserted between S10 and S20 through S0 and S5 at the start of the process. Therefore, the same reference numerals as those in FIG. 3 are assigned to steps in which the same processes as those in the start-time vehicle setting process shown in FIG. 3 are performed, and the description thereof will be omitted.

  In this process, when the process is started, it is first determined in S0 whether or not automatic adjustment is performed at the start of operation. That is, it is determined whether or not automatic adjustment of the seat position or the like has been made by the process of S50 in FIG. If automatic adjustment is performed at the start of operation (S0: Y), the process is terminated as it is not necessary to execute automatic adjustment again. If automatic adjustment is not performed at the start of operation (S0: N), The process proceeds to S5. In S5, based on the detection result of the shift position sensor 27, it is determined whether or not the shift position of the vehicle 1 is in the P range (parking range). If it is not the P range (S5: N), the process is in a standby state in S5 as it is, and if it is the P range (S5: Y), the process proceeds to S10 described above.

  When the authentication code input screen is displayed in the display area 11 in S10, the process proceeds to S15 and is in a standby state until the start switch 17 is operated (S15: N). During the standby in S15, a message prompting the driver D to operate the start switch 17 and input the authentication code by the line of sight E may be displayed in the display area 11. When the start switch 17 is operated (S15: Y), the process proceeds to S20 described above, and the input of the authentication code by the line of sight E is detected.

  Also, in this process, if the authentication code detected in S20 does not match the pre-registered authentication code (S30: N), and it is within the second time after the start of this process that does not match ( (S60: Y) After the re-input is instructed in S70, the process proceeds to S5 described above. Therefore, the driver D can input the authentication code again when the shift position is held in the P range (S5: Y).

[1-3. effect]
According to the first embodiment described in detail above, the following effects can be obtained.
[1A] In the present embodiment, the seat position and the like are automatically adjusted based on the input of the authentication code by the line of sight E. For this reason, even when a plurality of drivers D having similar faces such as parents and children, brothers, etc. drive one vehicle 1, it is possible to perform vehicle settings according to the driver D that has input the authentication code.

  [1B] In this embodiment, the authentication code can be input both when the vehicle 1 is turned on and after the movement is started. For this reason, even if the driver D forgets to perform the vehicle setting when the power is turned on or the vehicle setting fails, the driver D can perform the vehicle setting by inputting the authentication code after the vehicle 1 starts moving.

  [1C] In this embodiment, the authentication code is input using an existing configuration such as the head-up display 13 (configuration that can be used for other purposes). For this reason, the manufacturing cost of a vehicle setting apparatus can be reduced.

[1-4. Correspondence with Invention Specific Items]
In the above embodiment, the eye tracker 15 is the line-of-sight detection unit, the control ECU 20 is the determination unit, the control ECU 20, the electric seat 21, the electric mirror 23, and the handle adjustment device 25 are the vehicle setting unit, and the head-up display 13 is the image. Each corresponds to a display device. Further, among the processes of the control ECU 20, the process of S30 corresponds to the determination unit, and the process of S50 corresponds to the vehicle setting unit.

[2. Other Embodiments]
As mentioned above, although embodiment of this invention was described, this invention can take a various form, without being limited to the said embodiment.

  [2A] In the above embodiment, numbers are displayed on the display units 11A to 11D, but the present invention is not limited to this. For example, as illustrated in FIGS. 4B and 4C, Roman characters and hiragana may be displayed on the display units 11 </ b> A to 11 </ b> D, or other characters may be displayed. Furthermore, symbols may be displayed on the display units 11A to 11D, and various symbols such as fruits such as cherries and bananas, animals of the zodiac, and characters of famous animation may be displayed. In addition, the number and arrangement method of the display units may be variously changed, and the authentication code may be configured by using a part of the plurality of display units.

  [2B] In the above embodiment, the authentication code input screen is displayed on the head-up display 13, but the present invention is not limited to this. For example, an authentication code input screen that is small enough not to interfere with other displays may be displayed on a digital speedometer or the like, and an authentication code input screen may be displayed on the monitor of the navigation device. Furthermore, the display unit for inputting the authentication code with the line of sight E may not be formed on an image displayed on an image display device such as a monitor or a display. For example, a printing unit such as a dial of a mechanical meter or a car audio dial may be used as a display unit for inputting an authentication code. Also in this case, the eye tracker 15 can detect in which order the line of sight E moves on which of the display sections.

  However, when the display unit for inputting the authentication code with the line of sight E is configured to be hard to touch directly like the head-up display 13, the display unit is formed on the monitor image of the navigation device. As compared with the case where the display unit is directly touched by the hand as described above, the effect of the present invention is more remarkably exhibited.

  [2C] In the above embodiment, the seat position, the mirror position, and the handle position are set as the vehicle settings, but the present invention is not limited to this. For example, the vehicle setting may be setting of brightness and contrast of the monitor of the navigation device, setting of the drive mode of the engine of the vehicle 1, setting of the air conditioning temperature, and the like. And when setting of air-conditioning temperature etc. is made, this invention may be applied separately with respect to an auxiliary seat or a rear seat. That is, the vehicle occupant in the claims is not necessarily a driver.

  [2D] In the above embodiment, the case where the line of sight E sequentially moves on different display units 11A to 11D such as “1234” is taken as an example, but when the same number is consecutive as “1111”, It may be considered that when the blink is made, a plurality of inputs to the same display unit are made. Further, even if the line of sight E detected by the eye tracker 15 is slightly deviated from the centers of the display units 11A to 11D, control may be performed so that the line of sight E moves along the registered authentication code. In that case, a so-called calibration process for detecting a correction amount for improving the detection accuracy of the line of sight E by the eye tracker 15 may be executed in parallel with the process of S20.

  [2E] The timings at which the processes in FIGS. 3 and 5 are executed may be timings other than those described above, and the execution conditions of these processes may be appropriately changed. Further, only one of the processes in FIGS. 3 and 5 may be executed.

  [2F] The functions of one component in the above embodiment may be distributed as a plurality of components, or the functions of a plurality of components may be integrated into one component. In addition, at least a part of the configuration of the above embodiment may be replaced with a known configuration having a similar function. Moreover, you may abbreviate | omit a part of structure of the said embodiment as long as a subject can be solved. In addition, at least a part of the configuration of the above embodiment may be added to or replaced with the configuration of the other embodiment. In addition, all the aspects included in the technical idea specified only by the wording described in the claim are embodiment of this invention.

  [2G] The vehicle setting device described above may be retrofitted to the vehicle 1 at least in part. In addition to the vehicle setting device described above, the system includes the vehicle setting device as a component, a program for causing a computer to function as the vehicle setting device, a medium on which the program is recorded, a vehicle setting method, and the like. The present invention can also be realized.
