Summary of the Invention

Problems to be Solved by the Invention

[0005] In the alarm device described in the above-mentioned Patent Document 1, there is one control unit that controls the alarm unit. And when an abnormality occurs in the control unit, there is a problem that the two sound emitters, namely the speaker and the buzzer, cannot be used simultaneously. In a vehicle display device, since a display unit that displays the vehicle speed and a buzzer that outputs sound are controlled by one control unit, when an abnormality occurs in this control unit, the display unit and the buzzer cannot be used simultaneously, and the driver cannot confirm vehicle states such as the vehicle speed.

[0006] Therefore, the disclosed object is made in view of the above problems, and an object is to provide a vehicle control device that can continuously check the vehicle state even when an abnormality occurs in the control unit of the vehicle display device.

Means for Solving the Problems

[0007] The present disclosure employs the following technical means to achieve the above object.

[0008] The vehicle state output device disclosed herein is a vehicle control device that communicates with a vehicle state output device (110) including an image display unit (114) that displays the vehicle state as an image, a first sound output unit (118) that outputs the vehicle state as sound, and a first control unit (111) that controls the image display unit and the first sound output unit, and includes an abnormality detection unit (102) that detects an abnormality in the first control unit, a second sound output unit (204) that outputs sound in the vehicle interior of the vehicle, and a second control unit (101) that controls the second sound output unit to output the vehicle state as sound based on the abnormality detection unit detecting an abnormality in the first control unit.

[0009] According to such a vehicle control device, the abnormality detection unit detects an abnormality in the first control unit of the vehicle state output device. Then, based on the abnormality detection unit detecting an abnormality in the first control unit, the second control unit controls the second sound output unit to output the vehicle state as sound from the second sound output unit. As a result, even if sound cannot be output from the first sound output unit of the vehicle state output device due to an abnormality in the first control unit, sound can be output from the second sound output unit to notify the vehicle state in the vehicle interior.

[0010] Note that the reference numerals in parentheses for each of the above means are an example showing the correspondence with the specific means described in the embodiments described later.

Embodiments for Carrying Out the Invention

[0012] (First Embodiment) Regarding the first embodiment of the present disclosure, it will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, the vehicle display device 200 of the present embodiment is mounted on a vehicle, generates image data based on the sensing data of the vehicle, and displays the generated data in the vehicle interior. The vehicle display device 200 includes an HCU (Human Machine Interface Control Unit) 100 that generates image data, and a plurality of display devices that display the image data. In the present embodiment, as display devices, it includes a MID (Multi-Information Display) 110 and a CID (Center Information Display) 120. As shown in FIG. 2, HCU100, MID110, and CID120 are connected to be mutually data communicable. Further, HCU100 is connected to vehicle-side devices and is mutually data communicable.

[0013] HCU100, MID110, and CID120 each have a control unit. Each control unit executes a program stored in a storage medium and controls each part. Each control unit has at least one arithmetic processing unit (CPU) and a storage medium that stores programs and data. Each control unit is realized by, for example, a microcomputer including a computer-readable storage medium. The storage medium is a non-transitory physical storage medium that non-temporarily stores computer-readable programs and data. The storage medium is realized by a semiconductor memory or a magnetic disk, etc.

[0014] The HCU 100 is a vehicle control device that outputs and controls vehicle information. The HCU 100 includes an image generation unit 101 and a data processing unit 102. First, the data processing unit 102 will be described. The data processing unit 102 is connected to a vehicle sensor group 202 and other vehicle devices via a first communication interface 103. The data processing unit 102 acquires sensor signals from the sensor group 202. Examples of the sensor group 202 include a vehicle speed sensor that detects the vehicle speed, a rotation speed sensor that detects the engine speed, and an odometer sensor that detects the driving distance.

[0015] The data processing unit 102 also functions as an acquisition unit and acquires position information regarding the current position of the vehicle and legal speed information regarding the legal speed at the current position from other devices, such as a locator and a peripheral monitoring sensor, via the first communication interface 103. The locator reads map data around the current position from a map database and provides it to the data processing unit 102 together with locator information. The peripheral monitoring sensor is an autonomous sensor that monitors the surrounding environment of the host vehicle. The peripheral monitoring sensor detects, for example, moving objects such as pedestrians and other vehicles, as well as stationary objects such as road debris, guardrails, curbs, road signs, lane lines, and structures along the road shoulder, from the detection range around the host vehicle.

[0016] The data processing unit 102 is also connected to a vehicle switch group 203 via a first input interface 104. The data processing unit 102 acquires input signals from the switch group 203. Examples of the switch group 203 include an air conditioner switch for operating the air conditioner, an audio switch for operating the audio, a light switch for operating the lights, and a mode switch for operating the driving mode.

[0017] The data processing unit 102 generates sensing data based on the sensor signals from the sensor group 202 and the input signals from the switch group 203. The sensing data is information related to driving, such as vehicle speed information or total mileage information corresponding to the sensor signals, and indicator information corresponding to the input signals. The data processing unit 102 provides the generated sensing data to the image generation unit 101.

[0018] The data processing unit 102 is connected to the MID 110 via the second communication interface 107. Between the data processing unit 102 and the MID 110, they are connected in a data - communicable manner by a second communication path 206, which is different from the first communication path 205 described later. The second communication interface 107 of the second communication path 206 converts the sensing data into a data signal and transmits it to the MID 110.

[0019] Next, the image generation unit 101 will be described. The image generation unit 101 is a second control unit that acquires sensing data from the data processing unit 102 and generates image data based on the sensing data. Between the image generation unit 101 and the MID 110, they are connected in a data - communicable manner by a first communication path 205, which is different from the aforementioned second communication path 206. The first signal conversion IC (Integrated Circuit) 108 that constitutes this first communication path 205 converts the image data into a data signal and transmits it to the MID 110.

[0020] Also, between the image generation unit 101 and the CID 120, they are connected in a data - communicable manner by a third communication path 207. The first signal conversion IC 108 that constitutes this third communication path 207 converts the image data into a data signal and transmits it to the CID 120. In this way, the image generation unit 101 causes the display device corresponding to the generated image data to display the image data.

[0021] In addition, the image generation unit 101 is connected to the vehicle speaker 204 via the audio interface 105. The speaker 204 is a second sound output unit that outputs sound into the vehicle interior. As shown in FIG. 1, two or more speakers 204 are installed, for example, for the driver's seat, the passenger seat, and the rear seat. Thereby, the speaker 204 outputs voice information, such as music, to the vehicle occupants. Also, in the event of an emergency described later, the speaker 204 outputs a sound indicating the vehicle state and a guiding voice for guiding the warning into the vehicle interior.

[0022] Next, the MID 110 will be described. The MID 110 is an image display unit that displays at least the vehicle speed as the vehicle state, and is arranged in front of the driver's seat in the vehicle interior. The MID 110 displays a first vehicle image representing information related to the vehicle operation in color or monochrome for the occupants. The first vehicle image data is based on the image data generated by the image generation unit 101 of the HCU 100. The MID 110 includes a GDC (Graphics Display Controller) 111, a buzzer drive circuit 117, a buzzer 118, a first display 114, a first backlight illumination 115, and a non-volatile memory 116.

[0023] The first display 114 is an image display unit that displays the vehicle state as an image. The first display 114 is realized by a liquid crystal display and emits display light representing display information (image). The first display 114 has a first display drive IC 114a. The first display drive IC 114a performs drive control to display the first vehicle image data provided from the GDC 111.

[0024] The first backlight illumination 115 is disposed on the side opposite to the display surface of the first display 114. The first backlight illumination 115 emits light toward the first display 114. The light emitted by the first backlight illumination 115 partially passes through the first display 114, and the first display 114 displays an image. The first backlight illumination 115 has a driving IC 115a for the first backlight illumination. The driving IC 115a for the first backlight illumination performs lighting control based on the first vehicle image data provided from the GDC 111.

[0025] The MID 110 is connected to the image generation unit 101 of the HCU 100 via the third signal conversion IC 112. The third signal conversion IC 112 that constitutes the first communication path 205 between the image generation unit 101 receives a data signal from the second signal conversion IC 106 of the HCU 100.

[0026] The GDC 111 is a first control unit that controls the image output from the first display 114 and the electronic sound output from the buzzer 118. The GDC 111 generates a first vehicle image based on the image data converted from the received signal by the third signal conversion IC 112. The GDC 111 controls the display of the first vehicle image by the first display 114 and the transmissive illumination of the first display 114 by the first backlight illumination 115.

[0027] The MID 110 is also connected to the data processing unit 102 of the HCU 100 via the third communication interface 113. The third communication interface 113 that constitutes the second communication path 206 between the data processing unit 102 receives a data signal from the second communication interface 107 of the HCU 100. The GDC 111 processes the sensing data converted from the received signal by the third communication interface 113.

[0028] Also, GDC111 drives buzzer 118 via a buzzer drive circuit 117 to output an electronic sound into the vehicle interior. Buzzer 118 functions as a first sound output unit that outputs the vehicle state by sound. Buzzer 118 outputs a buzzer sound as a warning sound, for example, when a warning state that should be notified to the driver occurs. The warning state is, for example, when the vehicle is about to deviate from the lane during driving, when approaching the vehicle ahead, when the door is not properly closed, etc.

[0029] Buzzer 118 is realized by, for example, a piezoelectric buzzer and outputs an electronic sound by applying a voltage. The buzzer drive circuit 117 controls the amount and timing of the voltage applied to buzzer 118. The buzzer drive circuit 117 controls the voltage to buzzer 118 based on a command from GDC111.

[0030] Next, CID120 will be described. CID120 is arranged in the center cluster of the instrument panel in the interior of the vehicle as a second display device. CID120 color-displays or monochrome-displays a second vehicle image representing information related to the driving and interior habitability of the vehicle to the passengers. The second vehicle image is, for example, a navigation guidance screen, an air conditioner operation screen, and an audio device operation screen. The second vehicle image is based on the image data generated by the image generation unit 101 of HCU100. CID120 includes an MPU (Micro Processing Unit) 122, a liquid crystal type second display 123, and a second backlight illumination 124.

[0031] The second display 123 is realized by a liquid crystal display and emits display light representing display information (image). The second display 123 has a drive IC 123a for the second display. The drive IC 123a for the second display performs drive control to display the second vehicle image data given from MPU122.

[0032] The second backlight illumination 124 is disposed on the side opposite to the display surface of the second display 123. The second backlight illumination 124 emits light toward the second display 123. The light emitted by the second backlight illumination 124 partially passes through the second display 123, and the second display 123 displays an image. The second backlight illumination 124 has a drive IC 124a for the second backlight illumination. The drive IC 124a for the second backlight illumination performs lighting control based on the second vehicle image data provided from the MPU 122.

[0033] The CID 120 is connected to the image generation unit 101 of the HCU 100 via the fourth signal conversion IC 121. The fourth signal conversion IC 121 that constitutes the third communication path 207 between the image generation unit 101 receives the data signal from the first signal conversion IC 108 of the HCU 100.

[0034] The MPU 122 generates a second vehicle image based on the image data converted from the received signal by the fourth signal conversion IC 121. The MPU 122 controls the display of the second vehicle image by the second display 123 and the transmissive illumination of the second display 123 by the second backlight illumination 124.

[0035] Next, a configuration for detecting an abnormality of the vehicle display device 200 and fail-safe control when an abnormality is detected will be described. When an abnormality occurs in the GDC 111, an image different from the normal image display is displayed. When an abnormality occurs in the GDC 111, for example, the image displayed by the meter image may become a single color, for example, a black screen of black color. Also, when an abnormality occurs in the GDC 111, for example, the image displayed by the meter image may become a fixed screen where the image does not change.

[0036] Also, when an abnormality occurs in the GDC111, the buzzer 118 does not operate properly, so the buzzer sound may not be output in a warning state. Furthermore, when an abnormality occurs in the GDC111, for example, the sound output by the buzzer 118 may be different from the normal sound. When such an abnormality occurs in the GDC111, the vehicle speed and the like cannot be confirmed by the MID110. Therefore, as a fail-safe control, it is necessary to notify the vehicle speed and the like without using the MID110.

[0037] First, the abnormality detection will be described. The data processing unit 102 also functions as an abnormality detection unit that detects an abnormality in the GDC111. In the present embodiment, as an abnormality in the GDC111, the data processing unit 102 particularly detects a sound output abnormality in which the buzzer 118 cannot output a sound. For example, when the GDC111 cannot output a sound from the buzzer 118, the data processing unit 102 determines that an abnormality has occurred in the GDC111. As an example of determining the state of the GDC111, for example, the data processing unit 102 periodically exchanges messages with the GDC111, and when the response message disappears or an error response indicating an error of the buzzer 118 is returned, it is determined that a sound output abnormality has occurred in the GDC111. When the data processing unit 102 determines that a sound output abnormality has occurred in the GDC111, it outputs a signal indicating that the sound output abnormality has occurred to the image generation unit 101.

[0038] Also, the GDC111 detects its own abnormality by checking its internal circuit. Therefore, the GDC111 has an internal circuit which is an abnormality detection unit that detects its own abnormality. When the GDC111 detects a sound output abnormality in which the buzzer drive circuit 117 cannot be controlled by the internal circuit, the GDC111 transmits the result of this abnormality detection to the data processing unit 102. The sound output abnormality may be simply referred to as an "abnormality" hereinafter.

[0039] Next, the fail-safe control will be described. When the data processing unit 102 detects an abnormality in the GDC111, it converts the sensing data into a data signal and transmits it to the image generation unit 101, and further gives a command to output the vehicle state from the speaker 204.

[0040] The image generation unit 101 acquires sensing data from the data processing unit 102 and generates audio data based on the sensing data. Then, the image generation unit 101 supplies the audio data to the speaker 204 via the audio interface 105 and controls the speaker 204 to output the audio data. As a result, the vehicle state is output into the passenger compartment by sound from the speaker 204.

[0041] Next, the output control of the HCU 100 will be described using the flowchart of FIG. 3. The HCU 100 periodically executes the processes shown in FIG. 3. In step S11, it is determined whether there is an abnormality in the GDC 111. If there is an abnormality, the process proceeds to step S13. If there is no abnormality, the process proceeds to step S12. The presence or absence of an abnormality is determined by the determination process of the data processing unit 102 as described above.

[0042] In step S13, since there is an abnormality in the GDC 111, fail-safe control is implemented and the process proceeds to step S14. Details of the fail-safe control will be described later.

[0043] In step S14, it is determined whether the abnormality in the GDC 111 continues. If the abnormality continues, the process returns to step S13 and the fail-safe control continues. If the abnormality does not continue, the process proceeds to step S12.

[0044] In step S12, since there is no abnormality in the GDC 111, normal output control is implemented and this flow ends. The normal output control includes control to return the image display settings and volume settings that were implemented for fail-safe control to their normal settings. As will be described later, during fail-safe control, the volume of the speaker 204 is set for fail-safe control, so step S12 also includes a process to return the volume of the speaker 204 to the volume before switching to fail-safe control. Thus, when there is an abnormality in the GDC 111, fail-safe control is implemented. Also, when there is no abnormality in the GDC 111, a normal image is displayed.

[0045] Next, regarding the fail-safe control, it will be described using the flowchart of FIG. 4. The process shown in FIG. 4 is executed by the image generation unit 101. Also, the process shown in FIG. 4 is executed periodically in the state of fail-safe control, for example, at the timing of notifying the vehicle state.

[0046] In step S21, it is determined whether the volume of the speaker 204 is set for fail-safe use. If it is set, the process proceeds to step S23; if not, the process proceeds to step S22. In step S22, the volume of the speaker 204 is set for fail-safe use, and the process proceeds to step S23. The volume of the speaker 204 is set individually by the driver and is set to a volume for listening to music or the like, and there may be cases where the volume is too low. Also, for example, there may be cases where the mute setting is enabled. Therefore, it is set to the volume for fail-safe use so that it can be heard inside the vehicle in case of an emergency.

[0047] In step S23, it is determined whether a warning notice has been output. If the warning notice has been output, the process proceeds to step S25; if not, the process proceeds to step S24. In step S24, a warning notice is output, and the process proceeds to step S25.

[0048] The warning notice is a voice indicating that an abnormality has occurred in the GDC 111. The warning notice outputs voices such as "Currently, fail-safe control is in progress." and "An abnormality has occurred in the meter display. It will be announced by voice." Such a warning notice may be output periodically, for example, about once every few minutes, or only once when the vehicle is started, during the execution of fail-safe control.

[0049] In step S25, the image generation unit 101 controls the speaker 204 to output a guidance voice indicating the vehicle state, and ends this flow. The guidance voice is output according to the sensing data, for example, as the vehicle state, "Currently, the speed is 50 km / h.", "There is no warning display.", "The vehicle has deviated from the lane.", etc.

[0050] When outputting the guiding voice, if the sound of the vehicle state is associated with the direction with respect to the vehicle, it may be controlled to output the vehicle state by sound from the speaker 204 at the position corresponding to the associated direction. For example, the turn signal sound is output from the speaker 204 located on the right side when turning right, and is output from the speaker 204 located on the left side when turning left. Also, for example, the sonar warning sound outputs a warning sound or a warning voice from the speaker 204 located in the direction of the object to be warned. By the position where this is output, the driver can be informed of the direction.

[0051] As described above, the vehicle display device 200 of the present embodiment detects an abnormality of the GDC 111 which is the first control unit of the MID 110 by the data processing unit 102. Then, based on the fact that the data processing unit 102 has detected an abnormality of the GDC 111, the speaker 204 is controlled by the image generation unit 101 to output the vehicle state by sound from the speaker 204. As a result, even if the vehicle state cannot be output from the first display 114 and the buzzer 118 of the MID 110 due to an abnormality of the GDC 111, the vehicle state can be notified in the vehicle interior by outputting sound from the speaker 204.

[0052] In other words, due to a failure of the GDC 111 that controls the MID 110, in addition to a display defect of the MID 110, for example, when a black screen occurs, when a non-sounding failure of the buzzer 118 occurs, the user cannot be notified of the vehicle state. In order to suppress the inability to notify the vehicle state in such a case, the failure of the GDC 111 is detected by a system outside the MID 110, and the speaker 204 outside the MID 110 is used as an alternative means to notify the user.

[0053] Also, in the present embodiment, during fail-safe control set based on the detection of an abnormality, when outputting the vehicle state as sound from the speaker 204, it is controlled to output at the volume set for the abnormal situation to the speaker 204. In other words, when shifting to the fail-safe mode, when sounding the speaker 204, items that can be arbitrarily set by the driver such as the volume are temporarily fixed to values optimal for sounding the warning sound. Thereby, the volume can be automatically set to the fail-safe volume, and the passengers can be reliably notified.

[0054] Furthermore, in the present embodiment, during fail-safe control, it is controlled to output a voice indicating that an abnormality has occurred in the MID 110 from the speaker 204. In other words, it is notified to the user by voice that the buzzer sound from the MID 110 is replaced by the speaker 204 due to the abnormality of the MID 110. Thereby, the driver can recognize that an abnormality has occurred in the MID 110.

[0055] Also, in the present embodiment, during fail-safe control, a guidance voice indicating the vehicle state is output from the speaker 204. The speaker 204 can output not only buzzer sounds but also voices and the like. The meter display of the MID 110 is the main for state notification, and for warnings where it is difficult to accurately convey information to the user only by the sounding of the buzzer sound of the speaker 204, specific vehicle state notifications are made by voice using the speaker 204. By notifying the vehicle state such as the vehicle speed by voice, more specific information can be output.

[0056] Furthermore, in the present embodiment, when the sound of the vehicle state is associated with the direction with respect to the vehicle, it is controlled to output the sound of the vehicle information from the speaker 204 at the position corresponding to the associated direction. Thereby, depending on the position of the speaker 204, the driver can recognize the direction corresponding to the information.

[0057] (Other Embodiments) As described above, the preferred embodiments of the present disclosure have been explained. However, the present disclosure is not limited to the above-described embodiments at all, and various modifications can be made without departing from the gist of the present disclosure.

[0058] The structures of the foregoing embodiments are merely examples, and the scope of the present disclosure is not limited to the scope of these descriptions. The scope of the present disclosure is indicated by the description of the claims, and further includes all changes within the meaning and scope equivalent to the description of the claims.

[0059] In the foregoing first embodiment, the data processing unit 102 detects an abnormality of the GDC 111, but an abnormality may be detected by other configurations. For example, an abnormality of the image data may be detected by the first display driver IC 114a. Further, for example, the first display 114 may include an optical sensor in the image display unit, and the optical sensor may detect an abnormality. Further, an abnormality of the image display may be detected by another device that images the first display 114, such as an in-vehicle camera.

[0060] In the foregoing first embodiment, the MID 110 and the CID 120 are adopted as the display devices, but another display device may be further adopted. For example, an HUD (Head-Up Display) or the like may be adopted as the first display device or the second display device.

[0061] In the foregoing first embodiment, the buzzer 118 is used as the first sound output unit that outputs the vehicle state by sound, but it is not limited to the sound output unit that outputs the buzzer sound, and it may be a sound output unit that can output music and voice. Further, although the MID 110 functions as a vehicle state output device that outputs the vehicle state, it is not limited to the MID 110, and it may be a navigation device capable of sound. For example, when the control unit of the navigation device fails, the speaker 204 may be similarly controlled to notify the state of the navigation device.

[0062] In the foregoing first embodiment, the functions realized by the control units of the HCU 100, GDC 111, and CID 120 may be realized by hardware and software different from those described above, or a combination thereof. The control units of the HCU 100, GDC 111, and CID 120 may communicate with other control devices, for example, and other control devices may execute part or all of the processing. When the control units of the HCU 100, GDC 111, and CID 120 are realized by an electronic circuit, it can be realized by a digital circuit including a number of logic circuits or an analog circuit.

[0063] In the foregoing first embodiment, the vehicle display device 200 is used in a vehicle, but not all components are limited to being mounted on the vehicle, and at least a part thereof may not be mounted on the vehicle.

[0064] Also, in the foregoing first embodiment, the abnormality detection unit detects an abnormal sound output of the buzzer 118, but is not limited to such a configuration. Even when there is an abnormality other than an abnormal sound output in the GDC 111, control may be performed to output a sound notifying of the abnormality of the GDC 111 from a sound output unit other than the MID 110. Also, the second sound output unit is not limited to the speaker 204, and if there is another in-vehicle sound output unit, a sound notifying of the abnormality may be output from that sound output unit.
