Description

  The present invention relates to a vehicle information output device.

  Conventionally, a warning device (vehicle information output device) that determines a warning stimulus amount based on the illuminance outside the vehicle (the intensity of a disturbance factor) acquired by a surrounding environment detection unit (disturbance detection means) has been disclosed (for example, information output device for a vehicle) , See Patent Document 1). In the alert device described in Patent Literature 1, when the illuminance outside the vehicle becomes high, the information for alerting is displayed at a high illuminance so that the passenger can easily perceive the display even when the outside light is strong. It is configured.

JP 2009-31874 A

  However, there is a limit to the illuminance at the time of displaying information, and if the outside light becomes too strong, it becomes difficult for the passenger to perceive information for alerting. Furthermore, if the illuminance for displaying information is too high, the passenger may feel troublesome, shorten the life of the display, and increase the energy required for display. A similar problem occurs when noise is detected as a disturbance factor and the size of the alarm sound is determined according to the noise level.

  An object of the present invention is to provide an information output device for a vehicle that makes it easy for a passenger to perceive information while suppressing the output intensity of the information.

  In order to solve the above problems and achieve the object, the invention described in claim 1 is a disturbance detection unit including one or more detection units capable of detecting a disturbance factor that hinders the perception of information by a passenger, An information output unit having a plurality of output units capable of outputting a plurality of types of information different from each other by a person's perception method, and when the intensity of the disturbance factor detected by the disturbance detection unit exceeds a predetermined value, the disturbance A vehicle information output device comprising: control means for causing the output unit to output information having a different perception method from a factor.

  According to the first aspect of the present invention, when the intensity of the disturbance factor detected by the disturbance detection unit exceeds a predetermined value, the control unit outputs information whose perception method is different from that of the disturbance factor. Since the information is output to the unit, even if the intensity of the disturbance factor is high, the information output by the output unit can be easily perceived by the passenger. At this time, it is not necessary to increase the information output intensity with respect to the intensity of the disturbance factor, and the information output intensity can be suppressed.

  According to the invention described in claim 2, since the disturbance detection means has a plurality of detection units, the information is transmitted to the passenger while suppressing the output intensity of the information as described above with respect to the plurality of disturbance factors. It can be made easy to perceive.

  According to the third aspect of the present invention, when the disturbance detection means has an external light detection unit, when the intensity (illuminance) of the external light exceeds a predetermined value, the information output means outputs information other than light (for example, For example, even if external light such as sunlight passes through the windshield and reaches the eyes of the occupant, the output information is easily perceived by the occupant. Further, when the disturbance detection means has a noise detection unit, when the noise level exceeds a predetermined value, the information output means outputs information other than sound (for example, light and vibration). Even when the vehicle travels or road construction is performed around the vehicle and the noise outside the vehicle is large, the output information is easily perceived by the passenger.

  According to the fourth aspect of the present invention, when the information output means has the display unit, the image information can be perceived by the passenger even if the noise as a disturbance factor is large, for example. Further, when the information output means includes a speaker, for example, the passenger can perceive voice information even if the external light as a disturbance factor is strong. Further, when the information output means has a vibration part, for example, vibration information can be made to be perceived by the passenger even if the noise or the intensity of external light is high as a disturbance factor.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the vehicle information output device 1 according to the present embodiment is provided in a vehicle C and can output a disturbance detection unit 2 that can detect a disturbance factor that hinders information perception by a passenger, and can output information. The information output means 3 and the control means provided in ECU which is not shown in figure while controlling the information output means 3 are provided. In the present embodiment, the vehicle information output device 1 generates a warning to a passenger (driver) when a sonar (not shown) provided in the vehicle C detects the approach of another vehicle or the like. .

  The disturbance detection means 2 includes an external light detection unit 21 as a detection unit that detects external light as a disturbance factor, and a noise detection unit 22 as a detection unit that detects noise as a disturbance factor.

  The external light detection unit 21 is provided on the instrument panel I and is configured to measure the intensity of external light and transmit the measured value as a signal to the ECU. The external light detection unit 21 may be provided at an appropriate position where external light can be measured. For example, the external light detection unit 21 may be provided outside the vehicle or may be provided near the driver's eyes. .

  The noise detection unit 22 is built in the headrest H, and is configured to measure the magnitude of noise and transmit the measurement value as a signal to the ECU. The noise detection unit 22 may be provided at an appropriate position where noise can be measured. For example, the noise detection unit 22 may be provided outside the vehicle or may be provided in the instrument panel I. In addition, the noise detection unit 22 may detect noise including a reproduction sound from a speaker for music reproduction provided in the vehicle C, or may be detected from measurement sound in conjunction with a reproduction device that transmits an audio signal to the speaker. What removed the component by reproduced sound may be detected as noise.

  The information output means 3 includes a display unit 31 as an output unit that outputs image information, a speaker 32 as an output unit that outputs audio information, and a vibration unit 33 as an output unit that outputs vibration information.

  As shown in FIG. 2, the display unit 31 is provided on the meter panel M in the instrument panel I, and shows a vehicle unit 311 that shows the vehicle viewed from above, a front side, a front left side, a front side of the vehicle unit 311. And an approach display unit 312 arranged on the right, rear, rear left, and rear right. The sonar provided in the vehicle C is configured to be able to detect from which direction the other vehicle or the like is approaching, and by turning on or blinking the approach display unit 312 corresponding to the approach direction on the display unit 31, the approach direction can be determined. The image information can be communicated to the passenger. The display unit 31 may be provided in an existing display device such as a display screen of a car navigation system or a head-up display, or may be provided independently of the existing display device.

  The speaker 32 is provided on the door body D and is also used as a speaker for music playback. When a vehicle or the like approaches, an appropriate message corresponding to the approach direction (for example, “please be careful about the front”) ) Is configured to be playable. The speaker 32 may be provided at an appropriate position of the vehicle such as the instrument panel I, or may be provided independently of the speaker for music reproduction.

  The vibration unit 33 is a vibration motor built in the steering wheel W, and is configured to transmit a vibration signal to the poster by vibrating the steering wheel W when another vehicle or the like approaches. In addition, the vibration part 33 should just be provided in the position which a passenger contacts, for example, may be provided in seat SH.

  Hereinafter, an example of the detection output process executed by the control unit will be described with reference to the flowchart of FIG.

  When the vehicle C starts running, the control means starts detection output processing. First, the control means repeatedly determines whether or not an approach of another vehicle or the like has been detected based on a signal transmitted from the sonar (S100). When the sonar detects the approach of another vehicle or the like (Y in S100), the control unit determines whether or not the intensity L of the external light measured by the external light detection unit 21 is equal to or greater than a threshold value L0 (for example, 10000 lx). (S110). When the measured intensity L of external light is less than the threshold value L0 (N in S110), the control unit causes the display unit 31 to output image information (S120).

  On the other hand, when the measured intensity L of the external light is equal to or greater than the threshold value L0 (Y in S110), the control means determines whether or not the noise magnitude N measured by the noise detection unit 22 is equal to or greater than the threshold value N0 (for example, 80 dB). Is determined (S130). If the measured noise magnitude N is less than the threshold N0 (N in S130), the control means causes the speaker 32 to output audio information (S140). On the other hand, when the measured noise magnitude N is equal to or greater than the threshold value N0 (Y in S130), the control unit causes the vibration unit 33 to output a vibration signal (S150).

  Following the output of each information in each output unit (S120, S140, S150), the control means determines whether or not the approach of another vehicle or the like has been eliminated (160). If the approach of another vehicle or the like has not been eliminated (N in S160), the control unit returns to S110 again. On the other hand, when the approach of another vehicle or the like is canceled (Y in S160), the control unit stops the output of information to each output unit (S170), and returns to S100 again. Such detection output processing is always executed while the vehicle C is traveling, and ends when the vehicle C stops.

  By executing the detection output processing as described above, audio information or vibration information is output when the intensity L of the external light is higher than the threshold value L0, and vibration information is output when the noise level N is larger than the threshold value N0. Is output. In other words, when the intensity of the disturbance factor detected by the disturbance detection means 2 is equal to or greater than a predetermined value, information having a different perception method from the disturbance factor is output.

  According to this embodiment, there are the following effects. That is, the sound information or the vibration information is output when the intensity L of the external light is higher than the threshold value L0, and the vibration information is output when the noise level N is larger than the threshold value N0. Even if the output is high, it is possible to make the output information perceptible to the passenger, and it is not necessary to increase the output intensity of the information with respect to the intensity of the disturbance factor, and the output intensity of the information is suppressed. be able to.

  Furthermore, since the disturbance detection means 2 has the external light detection part 21 and the noise detection part 22, and the information output means 3 has the display part 31, the speaker 32, and the vibration part 33, two disturbance factors of external light and noise. On the other hand, it is possible to make the passenger easily perceive information while suppressing the intensity of the information to be output.

  In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.

  For example, in the embodiment, the determination of the intensity L of the external light (S110) is executed prior to the determination of the noise magnitude N (S130), and if both are equal to or less than the threshold value, the output from the display unit 31 has priority. However, S130 may be executed before S110, and the output from the speaker 32 may be prioritized. Further, after the output of the image information by the display device 31 (S120), the noise level may be determined (S130), and the image information and the audio signal may be output simultaneously. Further, when an approach of another vehicle or the like is detected, a vibration signal may always be output.

  In the above embodiment, when the intensity of the disturbance factor detected by the disturbance detection means 2 is equal to or greater than a predetermined value, information perceived by the same method as the disturbance factor is not output. As long as at least one piece of information with a different perception method is output, information perceived by the same method as the disturbance factor may be output at the same time. At this time, it is preferable that output information having a different perception method from the disturbance factor is emphasized. For example, the display intensity (brightness) of image information may be increased or displayed in a frame when the noise is high, and the volume may be increased when the outside light is strong. At this time, although the output intensity of information is slightly increased, it is not necessary to increase the intensity of the disturbance factor, and the output intensity of information can be suppressed.

  Moreover, in the said embodiment, although the disturbance detection means 2 shall have the external light detection part 21 and the noise detection part 22 as a detection part, a disturbance detection means is at least one of an external light detection part and a noise detection part. As long as it has.

  In the embodiment, the information output unit 3 includes the display unit 31, the speaker 32, and the vibration unit 33 as output units. However, the information output unit includes at least two of these output units. Just do it.

  In the above embodiment, the vehicle information output device 1 outputs information for warning when another vehicle approaches. However, the vehicle information output device 1 is not limited to when another vehicle approaches, for example, a pedestrian. Information may be output for warnings about the vehicle's running condition, such as when the vehicle is approaching, deviating from the lane, or when the steering angle of the steering wheel is suddenly changed. Information may be output for warnings regarding vehicle status such as Further, the information output by the vehicle information output device 1 is not limited to warning information, and may be, for example, guidance information (for example, information for guiding a route) in a car navigation system. Further, the passenger may arbitrarily select information to be output from the above information and other information, and the information may be output when a predetermined condition is satisfied.

  In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the invention has been illustrated and described primarily with respect to particular embodiments, but may be configured for the above-described embodiments without departing from the scope and spirit of the invention.
