  The present invention specifies a traveling state composed of one or both of the traveling direction and whether or not the vehicle can travel, and presents the identified traveling state in a form visually recognizable to a driver who is a user. The present invention relates to a display device.

  In a vehicle, shift position information (P, N, D, R, etc.) is displayed on a display such as a meter visible to the driver (Patent Document 1). This shift position information is visually recognized only as a notification of the current shift position, but besides that, it is possible to recognize the planned traveling direction of the vehicle (forward and backward) and whether or not the vehicle can travel (possible to advance or retract). It has the following effects.

Japanese Patent Laid-Open No. 10-016598

  However, the shift position information has a main purpose of recognizing the shift position, and at present, it does not display the vehicle's planned traveling direction and the state in which the vehicle can travel intuitively and easily. That is, the shift position is generally displayed with letters and numbers, and in order to recognize this as the scheduled direction of travel, it is said that those letters and numbers are replaced with the planned direction of travel and the possibility of progress in the head. Since thinking is required, it is hard to say that it is a kind of information that allows you to grasp the direction of progress and whether or not to proceed immediately by looking at it.

  An object of the present invention is to use information on vehicle forward, reverse, stop, etc. so that the vehicle can be intuitively recognized by using existing vehicle input information such as shift position information. A vehicle display device that can be visualized and displayed is realized at low cost.

When the planned progress direction specified by the progress state specifying means matches the progress prohibiting direction specified by the progress prohibiting direction specifying means, the vehicle is displayed with emphasis over the rest. Among the four direction indicating images indicating the four directions of front, rear, left and right, the user displays a non-progressible image indicating that the advancement is impossible in a form superimposed on the direction indicating image corresponding to the prohibition direction. a progress status presentation means for presenting to a visually recognizable to the driver,
It is characterized by providing.

  According to the configuration of the present invention, information such as forward, backward, and stop of the vehicle can be visualized and displayed using existing vehicle input information such as shift position information. It is possible to realize a vehicle display device that can intuitively recognize whether or not it is possible at low cost.

  Here, the traveling direction information includes input information that gives the vehicle function execution means a direction in which the vehicle can travel, and input information that gives the intended traveling direction of the user. Specifically, it is possible to cite advanceable direction information for executing vehicle control to make the vehicle advanceable in a predetermined direction as it is input to the vehicle function execution means. The direction of travel corresponds to the travelable direction as described above, and is included in the planned travel direction as described above. In addition to the direction information that can be traveled, it can include the direction information that the user intends to travel in the future, and the future direction of the vehicle that the user intends. Corresponds to the intended travel direction as described above, and is included in the planned travel direction as described above. Further, the advanceability information here includes input information that gives the vehicle function execution means whether the vehicle is in a state where it can travel or cannot progress. More specifically, this information is information for implementing vehicle control so that the vehicle can be advanced or cannot be made (at least in a state where the advance is hindered) when the accelerator is ON. The progress state presenting means determines whether or not the vehicle in the current state is in a travelable state, in which direction, or in which direction the travel is scheduled from the plurality of progress state information acquired from the plurality of vehicle function executing means. The direction in which the vehicle wants the vehicle to travel is comprehensively determined, and finally the traveling state of one vehicle is determined, which is visually displayed to the user. For example, if it is determined that the vehicle is ready to move forward in the current state of the vehicle, and if it is determined that the user's intention of traveling is the right turn direction, the vehicle's traveling state to be presented to the user with priority given to the user's intention Thus, it is possible to perform control so as to determine to proceed in the right direction.

  The vehicle function execution means according to the present invention includes at least a transmission that acquires shift position information input based on a predetermined shift operation by a user as progress state information, and further, based on a steering operation by the user as progress state information. It is configured to include one or both of a steering device that acquires steering angle information to be changed and a direction indicator that acquires instruction direction information input by a predetermined direction instruction operation by a user as progress state information it can. The transmission can acquire progress state information that reflects the planned traveling direction (forward and backward) and the propriety of traveling (progress and stop) of the vehicle, while the steering device and the direction indicator Since the planned traveling directions (left turn and right turn) are reflected, it is possible to display the planned traveling direction in the front / rear / left / right cross direction by combining these.

  Speaking individually, the transmission acquires shift position information based on a shift operation by the user, and switches the shift range based on the shift position information. The shift position information input by the user's operation is the vehicle's planned direction (forward and backward), such as “P” to stop, “D”, “1”, “2” etc. to advance, “R” to reverse. ) And propriety of progress (progress and stop) are reflected, and by acquiring this, the direction in which the vehicle can travel can be accurately specified and presented to the user. The steering device receives steering angle information that is changed by steering by a user of the steering wheel, and turns, for example, a wheel based on the input steering angle information. That is, the steering angle information changed by the user's steering and the displacement information of the operation unit operating in conjunction with the steering angle information (for example, the turning angle information of the tire) reflect the planned traveling direction to the left and right of the vehicle. Therefore, by acquiring one or more of these, it is possible to accurately specify the advancing direction on the left and right sides of the vehicle and present it to the user. The direction indicator acquires, for example, vehicle indication direction information based on the user's intention, which is selected by a direction indication operation to a dedicated operation unit, and turns on a direction indication display unit corresponding to the indication direction information. is there. The direction indicator does not give the traveling direction (travelable direction) fixed to the vehicle by the user operation, but receives the operation input in the traveling direction intended by the user, and acquires this. Thus, it is possible to accurately present to the user the planned traveling direction related to the left-right direction of the vehicle in consideration of not only the current state of the vehicle but also the user's intention.

  The progress state specifying means in the present invention specifies a travel direction of the vehicle as a progress state of the vehicle to any one of the four directions of the front, rear, left and right of the vehicle. The traveling direction specified by the means can be presented to the driver. By limiting the planned travel direction presented to the user to four directions, front, rear, left, and right, it becomes easier to intuitively grasp the planned travel direction of the vehicle.

  The progress state presenting means according to the present invention simultaneously displays on the predetermined display means direction indication images indicating the four directions of the front, rear, left and right of the vehicle, and is specified by the progress state specifying means among the direction indication images. It is possible to configure the display corresponding to the planned traveling direction with emphasis over the rest. According to this configuration, since all the possible traveling directions of the displayable vehicle are displayed and in which direction the vehicle travels are displayed, it is easier to understand than when the direction is vaguely indicated by a single arrow image or the like. .

  In the present invention, the display means is such that the display area is located on the front side of the vehicle with respect to the driver, the vertical direction of the display portion corresponds to the front-rear direction of the vehicle, and the left-right direction corresponds to the left-right direction of the vehicle. The progress state presenting means expresses a sense of perspective so that the one corresponding to the front of the vehicle among the four direction indication images can be seen in the back and the one corresponding to the rear of the vehicle in the foreground. Four direction indicating images can be displayed on the display means. This makes it easier to intuitively recognize the planned traveling direction due to the sense of perspective.

  As the display means, various existing vehicle-mounted display means such as a display means having a navigation screen mounted on a vehicle can be used. That is, it can also be used as a display means used by other vehicle function execution means. For example, as a head-up display, display may be made on the windshield side in front of the driver. In this case, the progress state display is made so as to be fixedly displayed at a predetermined display position on the windshield side. The driver's recognition is enhanced by using a dedicated display area.

  Moreover, you may use the display means which does not use a display screen like a display. For example, the progress state presenting means can be configured to display the specified planned traveling direction of the vehicle by the light emitting unit group arranged in a row toward the predetermined traveling direction of the vehicle. For example, the light emitting unit may form a cross or a line extending in each planned traveling direction, and the planned traveling direction of the vehicle may be expressed by the blinking flow of the light emitting units. This not only clearly recognizes the direction of travel, but is also effective as a decoration effect in the passenger compartment.

  In the present invention, a progress prohibition direction specifying means for specifying a travel prohibition direction of the vehicle is provided, and the progress state presenting means includes a progress prohibition direction in which the planned travel direction specified by the progress state specifying means is specified by the progress prohibition direction specifying means. If the direction matches, it can be configured to display that it is impossible to proceed. In this case, when it is determined that the displayed scheduled traveling direction is prohibited from traveling, it is displayed, so that it can be recognized in advance.

  In the case of a configuration in which the planned traveling direction of the vehicle is displayed with four direction instruction images indicating four directions, front, rear, left, and right, the progress state presenting means indicates a direction instruction corresponding to the travel inhibition direction among these four direction instruction images. It is possible to configure to display a non-travelable image indicating that it is impossible to proceed in a form superimposed on the image. According to this configuration, when the specified scheduled travel direction is prohibited, the progress impossible image is displayed in an overlapping manner on the image indicating the planned travel direction, so it is clear that the travel is impossible Can be recognized. In addition, since both the direction in which travel is possible and the direction in which travel is not possible are clearly clarified, when the travel direction is displayed as being incapable of travel, it is possible to easily find the direction to proceed while avoiding that.

  The travel prohibition direction specifying means can be an obstacle detection means for detecting an obstacle located within a predetermined detection range around the vehicle and specifying the detection direction. The detection direction of the obstacle detection means can be set as the travel prohibition direction. Thereby, it becomes possible to avoid contact with the obstacle of a vehicle. Further, the vehicle navigation device includes navigation data storage means for storing road map information and entry prohibition information for each road, and current position specifying means for specifying the current position of the vehicle. The means can also set a travel-prohibited direction from the current position specified in the in-vehicle navigation device to the road where travel is prohibited. As a result, it is possible to present an appropriate direction of travel based on road closure information and legal information such as one-way traffic.

In S2, the main control unit 10 sets the vehicle device 5 to be in a state where the vehicle can be advanced or cannot proceed as the vehicle device 5 is input to the vehicle device 5 among the collected plurality of progress state information. Whether or not the vehicle is actually capable of proceeding at the present time is specified from the information on whether or not the vehicle control is performed. Here, when the shift range is “P” in the transmission device 5A, and the parking brake operation is being performed in the parking brake device 5D, the vehicle is in a state in which the vehicle cannot travel. (S3: Yes) , otherwise, it is determined that the state can proceed (S3: No), and the process proceeds to S4 . If it is determined that the vehicle cannot travel, the process proceeds to S10, where the display unit 2 displays the display image 2 indicating that the vehicle is in the travel impossible state, and the process is terminated. For example, the display image 2 indicating that the vehicle is not allowed to travel is displayed by hiding the planned traveling direction as shown in FIG.

  In other words, in the present embodiment, when the vehicle travel impossible state is specified, it is displayed with higher priority than the planned travel direction specified from the remaining travel state information.

  In S4, the main control unit 10 sets the vehicle device 5 in a state that allows the vehicle device 5 to travel in a predetermined direction as it is input to the vehicle device 5 among the collected plurality of travel state information. The direction in which the vehicle can actually travel at the present time (the travelable direction) is specified from the travelable direction information for performing vehicle control.

Specifically, the main control unit 10 acquires the detection result (shift position information) of the shift position sensor of the transmission 5A, and the shift range specified based on the acquired detection result is “D” or “1”. ”,“ 2 ”, etc., the forward direction of the vehicle is specified as the front, and“ R ”, the forward direction of the vehicle is specified as the rear. Further, the main control unit 10 acquires the detection result (steering angle information) of the steering angle sensor of the steering device 5B, and predetermined leftward from a predetermined neutral position from the steering angle information specified based on the acquired detection result. When it is determined that the vehicle has changed beyond the level, the direction in which the vehicle can travel is identified as left, and when it is determined that the vehicle has changed from the predetermined neutral position to the right beyond the predetermined level, the vehicle travels. The possible direction is identified as right.

  Furthermore, here, in the case where both the travelable direction information for specifying the travelable direction in the vehicle front-rear direction and the travelable direction information for specifying the travelable direction in the vehicle left-right direction exist, Prioritizing the advancing direction information for specifying the advancing direction, the advancing direction in the vehicle left-right direction specified based on the advancing direction information is specified as the final advancing direction. For example, when the front is specified as the travelable direction of the vehicle and the right is specified as the travelable direction of the vehicle, the travelable direction finally specified is the right.

  In S5, the main control unit 10 is intended by the user from the intended traveling direction information that can identify the future traveling direction of the vehicle intended by the user among the collected traveling state information. Identify the future direction of travel of the vehicle (direction of travel intent). Here, the determination is based on whether or not the intended travel direction information has been acquired.

  Specifically, from the direction indicator 5C, the presence / absence of indication direction information detected based on the operation of the direction indication lever by the user is specified, and there is no indication direction information (that is, from the neutral position of the direction indication lever by the user). In the case of no movement operation), it is specified that there is no intended traveling direction. On the other hand, if there is instruction direction information, the intended traveling direction reflected in it is specified.

  In subsequent S6, the main control unit 10 determines whether or not the intended travel direction has been identified based on the identification result in S5. If the intended travel direction has been specified, the process proceeds to S11, where the specified result is prioritized over the travelable direction, and the direction indication image 21 (210) corresponding to the intended travel direction is emphasized over the remaining direction indication images 21. To display. On the other hand, if the intended traveling direction is not specified, the process proceeds to S7, and the direction indication image 21 (210) corresponding to the advanceable direction specified in S4 is prioritized from the remaining direction indication image 21 with priority given to the specification result of S4. Is also highlighted.

  In the present embodiment, the direction indication image 21 corresponding to the intended travel direction is displayed with emphasis over the remaining instruction image, and the direction indication image 21 corresponding to the advanceable direction is displayed more than the remaining instruction image. By displaying the highlighting method differently from the case of highlighting, it is possible to visually display to the user whether the planned traveling direction of the vehicle is a possible traveling direction or a traveling intention direction. Yes. Here, both the direction indication image 21 corresponding to the intended travel direction and the direction indication image 21 corresponding to the possible travel direction are displayed in a color different from that of the remaining direction indication image 21 and also correspond to the intended travel direction. The direction indication image 21 to be displayed is blinking display similar to the display of the direction indication display section (blinker display), and the direction indication image 21 corresponding to the travelable direction is displayed as non-flashing display. According to this, it becomes easy to intuitively understand that the display is the display of the intended travel direction from the blinking display.

  When the direction indication image 21 to be highlighted is determined in S7 or S11, it is next determined whether or not the vehicle can travel in the planned traveling direction corresponding to the direction indication image 21 (S8, S12). In the present embodiment, the determination is made based on the detection result of the obstacle detection means 7A which is the travel prohibition direction specifying means 7 and the road information of the in-vehicle navigation device 7B which is also the travel prohibition direction specifying means 7.

  Specifically, when the obstacle detection means 7A detects an obstacle located within a predetermined detection range around the vehicle, and the detection direction is specified, the main control unit 10 is specified. The detection direction information of the obstacle is acquired, and the detection direction is set as the travel prohibition direction. Then, it is determined whether or not the travel prohibition direction matches the planned travel direction corresponding to the direction indicating image 21 highlighted in S7 or S11. If they match, it is determined that the vehicle cannot travel in the scheduled travel direction (progress prohibition direction), and if they do not match, it is determined that the vehicle can travel in the planned travel direction. In the present embodiment, the corner sonars 7a to 7d constituting the obstacle detection means 7A are corner sonars (clearance sonar) 7a to 7d mounted on the corners of the front and rear bumpers of the vehicle. When an obstacle is detected, it is determined that the vehicle front and the vehicle right cannot travel, and the remaining direction is determined to be able to travel. When the corner sonar 7b detects an obstacle, it is determined that the vehicle front and the vehicle left cannot travel, and the remaining direction is determined to travel. When the corner sonar 7c detects an obstacle, it is determined that the vehicle cannot travel forward and to the right of the vehicle, and the remaining direction is determined to be able to travel. When the corner sonar 7d detects an obstacle, it determines that the vehicle front and the vehicle left cannot travel, and determines that the remaining direction can travel. When it is determined that the vehicle cannot travel in the planned traveling direction corresponding to the highlighted direction indication image 21, the main control unit 10 overlaps the direction indicating image 21 corresponding to the planned traveling direction, For example, a non-travelable image 222 as shown in FIG. 9 is displayed (S9, S13), and this process is terminated. If it is determined that it is possible to proceed, the direction indicating image 21 corresponding to the planned traveling direction remains highlighted, and this process ends.

  When the traveling direction from the current position to the road where entry is prohibited is identified in the in-vehicle navigation device, the main control unit 10 acquires the identified traveling direction and sets the traveling direction as the travel prohibition direction. . Then, it is determined whether or not the travel prohibition direction matches the planned travel direction corresponding to the direction indicating image 21 highlighted in S7 or S11. If they match, it is determined that the vehicle cannot travel in the scheduled travel direction (progress prohibition direction), and if they do not match, it is determined that the vehicle can travel in the planned travel direction. In the present embodiment, based on the road information stored in the HDD 74, the direction indication image 21 highlighted in S7 or S11 among the roads that can travel from the current position of the vehicle specified by the position detector 71 is supported. The road that exists in the planned direction of travel is identified, and traffic regulations such as one-way traffic on the road are read based on the road incidental information corresponding to the identified road, and entry to the road from the current position is permitted. It is determined whether or not it has been done. If it is permitted, it is determined that entry to the road is possible, and if it is not permitted, entry to the road is determined to be impossible. Further, roads that can be closed from the traffic information received by the wireless communication device 76 and that can travel from the current position of the vehicle that is specified by the position detector 71 based on the received traffic information (such as road closure information). Among them, it is determined whether or not the road existing in the planned traveling direction corresponding to the direction indication image 21 highlighted in S7 or S11 is allowed to pass, and if it is not closed, entry to the road is possible. If so, it is determined that entry into the road is impossible. When it is determined that the vehicle cannot travel in the planned traveling direction corresponding to the highlighted direction indication image 21, the main control unit 10 overlaps the direction indicating image 21 corresponding to the planned traveling direction, For example, the infeasible image 221 shown in FIG. 8 is displayed (S9, S13), and this process ends. If it is determined that it is possible to proceed, the direction indicating image 21 corresponding to the planned traveling direction remains highlighted, and this process ends.
