In this display control device, when the input device is operated by a driver who gets on the vehicle, the operation input determination unit determines the operation capability of the driver, and the display menu creation unit controls display of the operation menu. In this case, the display menu creation unit limits the number of hierarchies for the first menu information from the operation menu display process using the first menu information according to the driving load determined by the traveling state determination unit 14. 2. The timing for shifting to the operation menu display process using the menu information is determined based on the operation capability of the driver.

JP 2004-251756 A

  By the way, in the method disclosed in Patent Document 1, the transition timing of the operation menu display process is simply adjusted based on the operation capability of the driver. For example, in the case where the driver has made an erroneous operation, Depending on the operation, the display may change and you may feel bothersome.

  The present invention has been made in view of such circumstances, and an object thereof is to reduce the annoyance that the display is switched due to an erroneous operation of the driver.

  In order to solve such a problem, according to the present invention, the input means outputs a predetermined signal in response to an operation by the driver, and controls the vehicle display device based on the signal from the input means. Here, the input means outputs a contact detection signal when detecting that the operation element operable by the driver is operated with an operation force equal to or higher than the first determination value, and outputs the contact detection signal with an operation force larger than this. When it is detected that the operator has been operated, an operation detection signal is output. In this case, on the condition that a predetermined transition time has passed after the contact detection signal is input, display control corresponding to the operation of the operation element is performed according to the operation detection signal. It is variably set accordingly.

  According to the present invention, even in a driving scene in which an operator is erroneously operated, the transition time is appropriately set according to the driving environment.

  FIG. 1 is an explanatory diagram schematically showing the overall configuration of a vehicle display system according to an embodiment of the present invention. This vehicle display system includes an input device 10, a display control device 30 described later with reference to FIG. 4, and a display device 40, and is a system for displaying various types of information to passengers riding in the vehicle. It is.

  The input device 10 is disposed on the steering wheel 1. In this embodiment, the input device 10 is disposed on each of the left and right spokes that connect the outer ring 2 and the central boss 3. The input device 10 is operated by an occupant (driver) who operates the steering wheel 1, and outputs a predetermined signal corresponding to the operation by the driver to the display control device 30. Such signals are output to in-vehicle devices such as audio, television, navigation system, and camera as necessary. The driver can select an in-vehicle device desired to be operated and operate the selected in-vehicle device through the input device 10.

  FIG. 2 is an explanatory diagram schematically showing the configuration of the input device 10. FIG. 2A is a front view showing the input device 10, and FIG. 2B is an AA of the input device 10 shown in FIG. It is sectional drawing which shows a cross section. The input device 10 is mainly configured by a circuit board 11, first and second switches 12 and 13, and a key top (operator) 14.

  The circuit board 11 is a board on which the first and second switches 12 and 13 are mounted, and is electrically connected to the display control device 30.

  The first switch 12 is a switch (first detection means) that detects that the key top 14 is operated. For example, a contact type switch, a membrane switch, or the like can be used. The first switch 12 is discretely arranged on a predetermined circumference in order to detect the operation of the key top 14 by the driver. In this embodiment, the first switch 12 has a 90 degree pitch at four locations corresponding to the top, bottom, left, and right. Is arranged in. Each of the first switches 12 outputs a contact detection signal to the display control device 30 when a contact is turned on by a first contact switching unit 18a described later. Note that the display control device 30 can recognize which position of the contact detection signal output from each first switch 12 is output from the switch corresponding to the contact detection signal.

  On the other hand, the second switch 13 is a switch (second detection means) that detects that the key top 14 has been operated. Like the first switch 12, a contact type switch, a membrane switch, or the like is used. be able to. The second switch 13 is discretely arranged on a predetermined circumference in order to detect the operation of the key top 14 by the driver. Like the first switch 12, the second switch 13 is provided at four positions corresponding to the top, bottom, left and right. Arranged at a pitch of 90 degrees. Each second switch 13 outputs an operation detection signal to the display control device 30 when a contact is turned on by a second contact switching unit 18b described later. Note that the display control device 30 can recognize which position is output from the switch corresponding to the operation detection signal output from each second switch 13.

The first switch 12 and the second switch 13 are respectively arranged on two circumferences having different diameters and sharing a key top fulcrum 16 described later. Specifically, the first switch 12 is arranged on a first circumference having a predetermined diameter, and the second switch 13 is arranged on a second circumference having a larger diameter than the first circle. Has been.

  Here, the first switch 12 and the second switch 13 respectively detect that the key top 14 has been operated, and both of them detect sensitivity by operating force when the key top 14 is operated. Is different. Specifically, the first switch 12 detects this when the key top 14 is operated with an operation force equal to or greater than the first determination value, and outputs a contact detection signal. On the other hand, the second switch 13 detects this when the key top 14 is operated with an operation force equal to or larger than the second determination value larger than the first determination value, and outputs an operation detection signal.

  That is, the first switch 12 can detect this prior to the second switch 13 when the driver operates the key top 14. Thereby, the contact detection signal is output before the operation detection signal is output. In other words, the first switch 12 and the first switch 12 and 13 detect that the key switch 14 is operated by the first switch 12 at a timing preceding the detection timing by the second switch 13. Is different.

  In such a configuration, the operation detection signal functions as a signal for specific control as the operation of the key top 14, and the contact detection signal is a signal for detecting the operation of the key top 14 in advance. Function. In order to operate the on-vehicle device by operating the key top 14, the signal output from the second switch 13 may be encoded by the encoding means and transmitted to the on-vehicle device.

  The key top 14 is mainly composed of a key top main body 15, a key top fulcrum 16, and a flange portion 18. The input device 10 according to the present embodiment can accept four types of input operations corresponding to up, down, left, and right, which are representative operation positions, through the operation of the key top 14.

  The key top body 15 has a cylindrical shape with an opening on the lower surface side, and the surface on the upper surface side of the key top body 15 functions as a key top operation surface 15a for a driver to press using a finger. It is exposed on the surface of the spoke part. On the circular key top operation surface 15a, tactile guide portions 17 are arranged at respective positions of up, down, left and right which are operation positions. The tactile guide portion 17 is constituted by a protrusion formed on the surface of the key top operation surface 15a, and has an effect of visually recognizing the operation position of the key top 14.

  The key top fulcrum 16 stands at a predetermined position of the circuit board 11 and is positioned on the central axis of the key top body 15 to support the key top body 15. The key top fulcrum 16 is formed integrally with the key top body 15. The key top fulcrum 16 is configured to be tiltable in all directions around the standing position on the circuit board 11, thereby enabling the key top main body 15 and the flange portion 18 to tilt about the key top fulcrum 16. Yes. The key top fulcrum 16 is normally urged by an urging means (not shown) such as a spring so as to maintain a neutral position.

The flange portion 18 is formed by projecting the lower peripheral edge of the key top body 15 outward in the radial direction. A first contact switching portion 18 a extending downward is formed on the lower surface of the flange portion 18 so as to correspond to each of the first switches 12. The first contact switching unit 18a can switch the contact of the first switch 12 on by mechanically contacting the first switch 12 as the key top 14 is operated. Similarly, on the lower surface of the flange portion 18, second contact switching portions 18 b extending downward are formed in correspondence with the respective positions of the second switches 13. The second contact switching unit 18b
The contact of the second switch 13 can be switched on by mechanical contact with the second switch 13 as the key top 14 is operated.

  FIG. 3 is an explanatory diagram showing the operation of the input device 10. In the figure, (a) shows a state where the key top 14 is not operated by the driver, and (b) and (c) show a state where the key top 14 is operated by the driver.

  As shown in FIG. 5A, when the driver does not operate the key top 14, the key top fulcrum 16 holds the neutral position by the action of the urging means. A neutral position is maintained along with the above. In this neutral position, the flange portion 18 is parallel to the circuit board 11. In this case, the first contact switching portion 18a of the flange portion 18 is separated from the first switch 12 by a predetermined amount, and the second contact switching portion 18 is also separated from the second switch 13 by a predetermined amount. It has become.

  FIG. 5B shows a predetermined position of the key top operation surface 15a (for example, a position corresponding to the tactile guide portion 17 indicated by “arrow” in the figure) by the driver with a predetermined operating force (operation force ≧ first determination value). The state pressed with is shown. In this case, the key top main body 15 tilts around the key top fulcrum 16 and the flange portion 18 tilts at the same time. Along with this pressing operation, firstly, the first contact switching unit 18 a mechanically contacts the first switch 12. In this case, the first switch 12 outputs a contact detection signal. On the other hand, the second contact switching unit 18 b is still separated from the second switch 13 and does not come into contact with the second switch 13.

  FIG. 6C shows a state in which pressing is continued from the state shown in FIG. 5B with an operation force larger than the operation force in the state (operation force ≧ second determination value> first determination value). . In this case, the key top body 15 is further tilted, and the flange portion 18 is further tilted along with this. As a result, the first contact switching unit 18a mechanically contacts the first switch 12 secondarily while the first contact switching unit 18a continues to be in mechanical contact with the first switch 12. To touch. In this case, the first switch 12 outputs a contact detection signal, and the second switch 13 outputs an operation detection signal.

  When the pressure on the key top body 15 is released, the key top body 15 and the flange portion 18 return to the neutral position according to the biasing force acting on the key top fulcrum 16. The first and second switches 12 and 13 are switched off when the first and second contact switching units 18a and 18b release the contact, and the contact detection signal and the operation detection signal are output. Exit.

  Thus, in the present embodiment, the first switch 12 outputs a contact detection signal to the display control device 30 when a predetermined operating force is applied to the key top 14. This contact detection signal is output at a timing prior to the output timing of the operation detection signal by the second switch 13. Therefore, the first and second contact switching portions 18a and the first switch 12 are contacted with a smaller operating force than the contact between the second contact switching portion 18b and the second switch 13. The relationship between both the second switches 12 and 13 and the first and second contact switching units 18a and 18b is set appropriately.

The display control device 30 is a display control unit that controls the display device 40. In order to guide the operation of the input device 10, the display control device 30 displays an item corresponding to the operation position on the display device 40 as display content, or operates the driver based on a signal from the input device 10. Display control corresponding to the. Specifically, the display control device 30 determines the display contents to be displayed on the display device 40 and the display timing based on the contact detection signal and the operation detection signal from the input device 10, and based on this determination A display instruction is given to the display device 40.

  FIG. 4 is a block diagram functionally showing the configuration of the display control device 30. Here, the input device 10 mentioned above is comprised by the input part 20 and the contact detection part 21, when this is caught functionally. The input unit 20 has a function of outputting an operation detection signal corresponding to the operation of the driver, and specifically includes the plurality of second switches 13 described above. Further, the contact detection unit 21 has a function of outputting a contact detection signal on the premise of outputting an operation detection signal, and specifically includes the plurality of first switches 12 described above.

  As the display control device 30, a microcomputer mainly composed of a CPU, a ROM, a RAM, and an I / O interface can be used. When this display control device 30 grasps this functionally, the vehicle position detection unit 31, a road information storage unit 32, a road information acquisition unit 33, a scene determination unit 34, and a vehicle information acquisition unit 35 , An input interval determination unit 36, a display timing determination unit 37, and a display content creation unit 38.

  The own vehicle position detection unit 31 detects the position of the own vehicle (own vehicle position) and the traveling direction of the own vehicle. For example, the own vehicle position detection unit 31 performs calculations using autonomous navigation based on information output from various sensors such as a geomagnetic sensor and a gyro, a GPS receiver, and the like. The own vehicle position detection unit 31 can update the own vehicle position and the traveling direction at any time in real time even when the own vehicle is traveling (for example, information is updated every 5 Hz).

  The road information storage unit 32 includes a collection of vector data representing road shapes as points (nodes, complementary points) and lines (links), and point information stored as unique information for each latitude and longitude. Road information is stored. Road attribute data is added to each point and link. The latitude, longitude, and road curvature information are added to the points as attribute data, and the road type (national road, city road, highway, parking area, etc.) and road width are added to the links as attribute data. . The point information includes position information such as latitude and longitude, information content including road curvature, recommended speed, road surface μ, parking area, and the like, and an icon indicating the information content.

  The road information acquisition unit 33 performs map matching processing with road information stored in the road information storage unit 32 based on the position and traveling direction of the host vehicle detected by the host vehicle position detection unit 31. The road information acquisition unit 33 then calculates the road shape (hereinafter referred to as “peripheral road information”) within a certain distance (for example, 100 m ahead) starting from the position on the matched link and the surroundings of the road within the certain distance. And point information (hereinafter referred to as “neighboring point information”).

  Note that the road information storage unit 32 does not need to be independently owned by the display control device 30, and when the navigation system is mounted on the vehicle as an in-vehicle device, the road information storage unit 32 uses the road information held by the navigation system. Alternatively, the road information held by a server in a remote place may be acquired and used using a communication means such as a mobile phone or a wireless LAN. Further, the road information acquisition unit 33 uses the own vehicle position detection unit 31 and the road information storage unit 32 to search for the surrounding road information and the surrounding point information independently, and the navigation system is installed in the vehicle as an in-vehicle device. If it is installed, the navigation system may acquire information searched by cooperating with this.

The scene discriminating unit 34 discriminates a scene where the erroneous contact with the input device 10 (specifically, the key top 14) by the driver is high, and determines “display delay” to be described later according to the discrimination result. In determining the scene, the scene determination unit 34 is acquired by the peripheral information (specifically, peripheral road information and peripheral point information) acquired by the road information acquisition unit 33 and a vehicle information acquisition unit 35 described later. Vehicle information is used.

  The vehicle information acquisition unit 35 acquires vehicle information, that is, information related to the vehicle. Examples of the vehicle information include information such as an instruction value corresponding to the amount of depression of the accelerator pedal, steering angle, lateral acceleration, vehicle speed, distance between vehicles, and presence / absence of turn signal operation. The vehicle information can be acquired through the in-vehicle LAN, but information may be acquired through individually installing a sensor or the like at the target site.

  When the operation detection signal is input from the input unit 20, the input interval determination unit 36 stores the input time of the signal. Then, the input interval determination unit 36 refers to the previously input time stored in advance, and determines whether or not the time interval is a predetermined time (for example, 500 msec) or less. When an affirmative determination is made by this determination (time interval ≦ predetermined time), the input interval determination unit 36 sets the control flag to “1” indicating that the operation interval is short. On the other hand, when a negative determination is made based on this determination (time interval> predetermined time), the input interval determination unit 36 sets the control flag to “0”.

  The display timing determination unit 37 displays the display content corresponding to the operation detection signal from the input unit 20 on the display device 40 based on the determination result of the scene determination unit 34 and the control flag set in the input interval determination unit 36. The display timing to be displayed is determined.

  The display content creation unit 38 creates display content to be displayed on the display device 40 based on the operation detection signal from the input unit 20 and the input of the contact detection signal from the contact detection unit 21. For example, when causing the driver to select an in-vehicle device, the display content creation unit 38 displays the display content including items corresponding to each in-vehicle device on the display device 40 and prompts the selection of the in-vehicle device. As shown in FIG. 5, a case is assumed in which four items are displayed as display contents corresponding to the operation position of the key top 14. In this case, when the upper portion of the key top operation surface 15a is pressed by the driver, the display content creation unit 38 highlights the item corresponding to the position highlighted (visually distinguishable including reverse display). Display content that produces a special effect).

  The display device 40 is disposed on a part of an instrument panel, for example, an instrument panel (upper meter) including meters such as a speedometer, and includes a liquid crystal display, an organic EL (Electro-Luminescence) display, and the like. A display unit 41 is provided. The display device 40 displays predetermined information on the display unit 41 in response to a display instruction from the display control device 30 or a display instruction from the in-vehicle device. The display device 40 is not limited to the above-described configuration, and may be disposed in the center cluster unit, a head-up display that displays an image on a windshield, or the like.

  Hereinafter, the operation of the display control device 30 according to the present embodiment will be described. This operation consists of three processes: scene discrimination, display timing determination, and display content creation.

  FIG. 6 is a flowchart showing a procedure for scene discrimination. The flowchart shown in the figure is called at a predetermined cycle (for example, 10 msec) and executed by the display control device 30.

  First, in step 10 (S10), the host vehicle position detection unit 31 detects the position of the host vehicle (current position) and the traveling direction of the host vehicle. For example, the position of the host vehicle is represented by latitude and longitude, and the traveling direction of the host vehicle is represented by a clockwise angle with 0 degree when the traveling direction of the host vehicle is the north direction.

  In step 11 (S11), the road information acquisition unit 33 acquires peripheral information based on the current position and the traveling direction and the road information stored in the road information storage unit 32. This peripheral information corresponds to peripheral road information and peripheral point information.

  In step 12 (S12), the vehicle information acquisition unit 35 acquires vehicle information.

  In step 13 (S13), the scene discriminating unit 34 refers to the surrounding road information acquired in step 11 and determines whether or not the vehicle is in front of the branch point, that is, whether or not the branch point exists within a predetermined distance. Judging. If an affirmative determination is made in step 13, that is, if a branch point exists, the process proceeds to step 17 (S17) described later. On the other hand, if a negative determination is made in step 13, that is, if there is no branch point, the process proceeds to step 14 (S14).

  In step 14, the scene discriminating unit 34 refers to the surrounding road information acquired in step 11, and determines whether or not the vehicle is in front of the curve, that is, whether or not there is a curve having a predetermined curvature or more within a predetermined distance. to decide. If an affirmative determination is made in step 14, that is, if a curve exists, the process proceeds to step 17. On the other hand, if a negative determination is made in step 14, that is, if there is no curve, the process proceeds to step 15 (S15).

  In step 15, the scene determination unit 34 determines whether or not the steering angle of the steering is within a predetermined range (for example, 80 ° to 100 °) based on the vehicle information acquired in step 12. If an affirmative determination is made in step 15, that is, if the steering angle is within a predetermined range, the process proceeds to step 17. On the other hand, if a negative determination is made in step 15, that is, if the steering angle is not within the predetermined range, the process proceeds to step 16 (S16).

  In step 16, the scene determination unit 34 determines whether or not the winker is operated based on the vehicle information acquired in step 12. If an affirmative determination is made in step 16, that is, if the winker is being operated, the process proceeds to step 17. On the other hand, if a negative determination is made in step 16, that is, if the winker is not operated, the process proceeds to step 18 (S18).

  In step 17, the scene determination unit 34, based on the determination result of each step described above, is a scene in which the current driving scene is highly erroneous contact with the input device 10 (specifically, the key top 14) by the driver. Judge. Then, the scene determination unit 34 sets “display delay” to “medium” and outputs this to the display timing determination unit 37. Here, “display delay” means that a predetermined period after the contact detection signal is input, even if the operation detection signal is input after that, the display corresponding to the operation detection signal is not performed and the period has elapsed. This is a parameter for setting a period for performing display corresponding to an operation detection signal to be input later. In the present embodiment, “display delay” has two elements, “medium” and “small”, and “medium” has a longer period than the “small”. Is set to For example, “middle” can be 500 msec, and “small” can be 200 msec.

  In step 18, the scene determination unit 34 determines that the current traveling scene is not a scene in which the erroneous contact with the input device 10 (specifically, the key top 14) by the driver is high based on the determination result of each step described above. to decide. Then, the scene determination unit 34 sets “display delay” to “small”, and outputs this to the display timing determination unit 37.

Next, a display timing determination processing procedure will be described. The display timing determination unit 37 determines the display timing based on the display delay set by the scene determination unit 34 and the control flag set by the input interval determination unit 36, and instructs this to the display content creation unit 38. To do. Specifically, when the display delay is medium, the display timing determination unit 37 instructs the display content creation unit 38 to display the medium display delay. On the other hand, when the display delay is small, the display timing determination unit 37 instructs the display content creation unit 38 to display a small display delay. On the other hand, when the control flag in the input interval determination unit 36 is set to “1”, the display timing determination unit 37 instructs the display content creation unit 38 not to perform display switching for a predetermined time.

  Next, a display content creation processing procedure will be described. The display content creation unit 38 issues a display instruction to the display unit 41 based on the detection result (contact detection signal) of the contact detection unit 21 and the instruction of the display timing determination unit 37. Specifically, when the display delay is instructed to be medium, the display content creation unit 38 displays the display according to the operation detection signal after a medium time (for example, 500 msec) has elapsed after the input of the contact detection signal. To the display unit 41. On the other hand, when the display delay is instructed to be small, the display content creation unit 38 displays a display corresponding to the operation detection signal after a small time (for example, 200 msec) has elapsed after the input of the contact detection signal. Go to 41. On the other hand, when it is instructed not to perform display switching for a predetermined time, the display content creation unit 38 does not change the display content for a predetermined time (for example, 500 msec) regardless of whether or not a contact detection signal is input.

  As described above, according to the present embodiment, the input device 10 makes contact when detecting that the key top 14 that can be operated by the driver and that the key top 14 is operated with an operation force equal to or greater than the first determination value. The first switch 12 that outputs a detection signal to the display control device 30 and the operation when the key top 14 is detected to be operated with an operation force equal to or greater than a second determination value that is greater than the first determination value. And a second switch 13 that outputs a detection signal to the display control device 30.

  In this case, the display control device 30 performs display control corresponding to the operation of the key top 14 according to the operation detection signal on the condition that a predetermined transition time has elapsed after the contact detection signal is input, This transition time is variably set according to the operating environment.

  According to such a configuration, even in a driving scene where a key top is erroneously operated, the transition time is appropriately set according to the driving environment. Thereby, since the situation where the display of the display part 41 switches by mistaken operation can be suppressed, annoyance can be reduced.

  In the present embodiment, the display control device 30 further includes a vehicle information acquisition unit (vehicle information acquisition unit) 35 that acquires vehicle information indicating the state of the vehicle as the driving environment described above. Here, the display control device 30 switches the transition time according to the steering angle that is vehicle information.

  According to such a configuration, display switching can be suppressed even in a case where the key top 14 is touched without intention to operate in the driving environment during steering. This is particularly effective in the display device 40 that is not shielded by the steering wheel 1 and disposed in the upper meter or the center cluster unit, or the display device 40 that uses a head-up display.

  In the present embodiment, the display control device 30 further includes a road information acquisition unit (road information acquisition unit) 33 that acquires road information as a driving environment. Here, the display control device 30 switches the transition time according to the road shape ahead of the host vehicle, which is road information.

  According to such a configuration, it is possible to suppress screen switching when the touch switch is touched without an operation intention in a driving environment where the driving load is high for the driver, such as branching or merging.

  In the present embodiment, the display control device 30 further includes an input interval determination unit (input interval determination unit) 36 that determines an input interval of an operation detection signal corresponding to the operation frequency of the key top 14 as an operating environment. Here, the display control device 30 switches the transition time according to the input interval of the operation detection signal.

  According to such a configuration, it is possible to suppress screen switching according to the on / off change of the first switch 12 in an operating environment in which the operator continuously operates the key top 14.

  As mentioned above, although the vehicle display system concerning embodiment of this invention was demonstrated, it cannot be overemphasized that a various deformation | transformation is possible for this invention within the scope of the invention, without being limited to embodiment mentioned above. . The present invention functions not only as such a system configuration but also as a part of the present invention.
