  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 are diagrams showing a first embodiment of an in-vehicle display control apparatus according to the present invention.

  First, the configuration will be described. FIG. 1 is a block diagram showing a configuration of an in-vehicle display control apparatus according to the present invention. In FIG. 1, the in-vehicle display control apparatus includes an operation setting unit 10, an acceleration detection unit 11, a traveling state detection unit 12, a display image generation unit 13, and a display unit 14.

  The acceleration detection means 11 is composed of, for example, an acceleration sensor or the like, and detects acceleration applied in the left-right direction of the vehicle and outputs acceleration information to the traveling state detection means 12. The traveling state detection unit 12 outputs the traveling state of the vehicle detected by the acceleration detection unit 11 to the display image generation unit 13.

  The display image generation unit 13 generates a display image for notifying the situation on the occupant's body with respect to the driving situation detected by the driving situation detection unit 12 and outputs the display image to the display unit 14. The display means 14 is composed of, for example, a liquid crystal display, an EL display, and the like, and displays an image according to the situation exerted on the occupant's body with respect to the running situation.

  The operation setting unit 10 is configured to set the operation of the display image generation unit 13 to be valid or invalid, and includes a mechanical switch, a touch panel, and the like. When the operation for enabling the display image generation unit 13 is performed by the operation setting unit 10, control for notifying the situation exerted on the occupant's body is executed, and the operation setting unit 10 is used for invalidating the display image generation unit 13. Is performed, the control for notifying the situation affecting the occupant's body is not executed.

  Next, an image display method will be described with reference to FIGS.

  First, before starting traveling, the operation setting unit 10 is turned on to enable the operation of the display image generation unit 13. When the vehicle is traveling straight at a constant speed, no horizontal acceleration is applied to the vehicle, and the image displayed on the display means 14 is not changed. However, when the vehicle turns left or turns left, the acceleration detecting means 11 detects the acceleration in the left direction, so that the display image generating means 13 is based on the detection information of the acceleration detecting means 11, for example, FIG. A person image (character) indicating that the vehicle travels in the left direction as in a) is generated and displayed on the display means 14.

  The display unit 14 displays or blinks the person image on the entire screen or a part of the screen to alert the occupant. On the other hand, when the vehicle turns right or turns right, for example, a person image indicating that the vehicle proceeds in the right direction as shown in FIG. Or it blinks.

  In addition to the information on the direction of the acceleration detected by the acceleration detecting means 11, information on the magnitude of the acceleration may be used. In this case, the display image generating means 13 is a different image depending on the direction and magnitude of the acceleration. Is generated.

  Further, the acceleration detection means 11 may further detect acceleration in the front-rear or vertical direction of the vehicle. In this case, the display image generation means 13 corresponds to the direction and magnitude of the acceleration in the front-rear, vertical, and left-right directions. Generate an image.

  The display image generation means 13 may generate an image corresponding to the direction and magnitude of acceleration in advance. In this case, a storage means for storing the generated image is provided, and the display image generation means 13 is provided. Is output from the storage means by the display image generation means 13 when the image is output.

  Further, the image generated by the display image generation unit 13 is not an image indicating that the vehicle has traveled in the right direction when the vehicle turns right or turns in the right direction, but an image in which the display position is shifted in the left direction. May be.

  That is, as shown in FIG. 3A, when the vehicle turns right or turns right, that is, when the acceleration detection means 11 detects leftward acceleration, the image 15 displayed at the center of the screen when going straight is As shown in FIG. 3B, an image 16 in which the display position is shifted leftward may be used. Further, instead of the image shifted in the horizontal direction, as shown in FIGS. 3C and 3D, an image 17 rotated left and right or an image 18 rotated right may be displayed.

  In addition, when the image display position is in the center, there may be a plain image area around the image to be displayed. In this case, the plain image area displays the shifted image when the image is shifted. Used to do.

  Note that the image generated by the display image generation unit 13 is not an image obtained by shifting the display position to the left when the vehicle turns right or turns right, as shown in FIG. A trapezoidal image 19 in which the left side and the right side are parallel, the left side is a short side, and the right side is a long side may be generated. Further, when acceleration is applied in the vertical direction of the vehicle, a trapezoidal image in which the upper side and the lower side of the image are parallel may be generated.

  In the case of the trapezoidal shape, for example, the turning direction of the vehicle may be long. FIG. 3E shows a trapezoidal image 19 indicating that the vehicle has turned rightward. Of course, the turning direction of the vehicle may be short. In this case, in FIG.3 (e), it becomes the trapezoid image 19 which shows having turned left.

  Here, the relationship between the detected direction of acceleration and the direction in which the image is shifted or the method of converting the image shape is not limited to this. The same operation including acceleration detection is performed not only when the vehicle starts to turn right and left and turns, but also when the vehicle has finished turning right and left. The display means 14 is not limited to a liquid crystal display or an EL display, and may be configured by a projector and a screen that displays an image projected thereby.

  Similarly, when the vehicle suddenly accelerates or brakes suddenly, the image may be enlarged or reduced. In this case, the enlargement or reduction ratio corresponds to the magnitude of the acceleration detected by the acceleration detecting means 11. To do. In addition, when the vertical and horizontal movements of the vehicle overlap with sudden acceleration or braking, corresponding image changes may be combined.

Further, the acceleration may be obtained as v ² / r by detecting the vehicle speed v and the traveling direction angle θ to obtain the turning radius r of the vehicle. In this case, the vehicle speed v can be obtained, for example, from a vehicle speed pulse signal output from a wheel speed sensor installed on the wheel.

Further, the traveling direction angle θ can be detected from the steering angle of the vehicle by, for example, a steering angle sensor. Here, the direction of acceleration can be known from the traveling direction angle θ. Instead of the wheel speed sensor, the angular velocity sensor may detect the angular velocity ω in the yaw direction of the vehicle, and the acceleration may be obtained as rω ² .

Here, the direction of acceleration can be known from the sign of the angular velocity ω. As another method for detecting the acceleration in the left-right direction of the vehicle, for example, it can be obtained from a navigation device installed in the vehicle. In this case, if the turning radius r of the vehicle is obtained from the vehicle position information and the set route information of the navigation device, and the vehicle speed v is obtained from the time change of the vehicle position information, the acceleration in the left-right direction is similarly v ^2. / R. In this case, the turning radius r of the vehicle may be obtained by detecting the traveling direction angle θ from the steering rudder angle sensor described above from the point of accuracy.

  As described above, in the present embodiment, the traveling state detection unit 12 detects the traveling state based on the detection information from the acceleration detection unit 11, and the display condition generation unit 13 detects the traveling state detected by the traveling state detection unit 12. Since an image for notifying the situation affecting the occupant's body is generated and this image is displayed on the display means 14, the vehicle running status changes such as turning left / right, turning, sudden acceleration / braking, etc. By doing so, even if the position of the eyes of the passenger of the vehicle has moved, the image on the display device can be visually recognized comfortably.

  In particular, when an occupant such as a child concentrates the consciousness on the image displayed on the display means 14 and is not looking at the scenery outside the vehicle, the influence of acceleration in the left-right direction of the vehicle is large, so The video can be viewed more comfortably.

  Further, since the traveling state detection unit 12 detects the traveling state of the vehicle based on the detection information of the acceleration detection unit 11, the traveling state such as turning right / left or turning, sudden acceleration / braking is surely and easily performed. Can be detected.

  Even when the acceleration detecting means 11 is composed of a steering rudder angle sensor (steering turning angle detecting means) for detecting the turning angle of the steering of the vehicle and a speed detecting means for detecting the speed of the vehicle, It is possible to reliably detect the traveling state of the turn.

  Moreover, since the image in which the character moves is generated in accordance with the traveling state detected by the traveling state detecting means 12, an image without getting tired can be obtained. Further, instead of the character, one or more objects, for example, one or more spaceships or airplanes may be displaced according to the traveling state.

  Further, in the present embodiment, since the operation setting unit 10 for setting the operation of the display image generation unit 13 to be valid or invalid is provided, the operation of the status notification by the display image generation unit 13 is made effective when the occupant is necessary. Can inform the driving situation.

  2 to 6 are views showing a second embodiment of the in-vehicle display control apparatus according to the present invention.

  First, the configuration will be described. FIG. 4 is a block diagram showing the configuration of the in-vehicle display control device of this embodiment. In FIG. 4, the on-vehicle display control device includes an acceleration detection means 21, a travel situation detection means 22, a position detection means 23, a route guidance means 24, a travel situation prediction means 25, a display image generation means 26, a display means 27, a destination. Setting means 28 and operation setting means 29 are provided, and some means are shared with the navigation apparatus.

  The acceleration detection means 21 is composed of, for example, an acceleration sensor, and detects acceleration in the left-right direction of the vehicle and outputs acceleration information to the traveling state detection means 22. The position detection means 23 is provided in the navigation device, and includes an autonomous navigation sensor including an angular velocity sensor that detects the rotational angular velocity of the host vehicle and a distance sensor that detects a travel distance of the host vehicle, and a current position and a current direction of the vehicle. The GPS receiver includes a GPS receiver that performs positioning by satellite navigation, and an own vehicle position calculation device that calculates an own vehicle position based on inputs from the autonomous navigation sensor and the GPS receiver.

  The route guidance means 24 is provided in the navigation device, has a storage unit for storing map data, and creates route data to the destination based on the destination setting information and the map data to guide the driver. It is supposed to be.

  The traveling state detection unit 22 outputs the traveling state of the vehicle detected by the acceleration detection unit 21 and the position detection unit 23 to the traveling state prediction unit 25. The destination setting means 28 is provided in the navigation device, sets the destination by user input, and outputs destination setting information.

  The driving situation prediction means 25 predicts the driving situation of a near future vehicle of about several seconds based on the driving situation and route data, and outputs prediction information to the display image generation means 26.

  The display image generation means 26 generates a display image based on the detected traveling situation and outputs the display image to the display means 27. Composed.

  The operation setting unit 29 is configured to enable or disable the operation of the display image generation unit 26, and includes a mechanical switch, a touch panel, and the like. When the operation for enabling the display image generation means 26 is performed by the operation setting means 29, a control for notifying the situation exerted on the occupant's body is executed, and the operation setting means 29 for invalidating the display image generation means 26 Is performed, the control for notifying the situation affecting the occupant's body is not executed.

  Next, an image display method will be described with reference to FIGS. 2, 3, 5, and 6. FIG.

  First, before starting traveling, the operation setting unit 29 is turned on to enable the operation of the display image generation unit 26. When the traveling state detecting unit 22 detects the traveling state from the acceleration information detected by the acceleration detecting unit 21 and the position information detected by the position detecting unit 23, the traveling state predicting unit 25 uses the route data held by the route guiding unit 24. Based on this, predict the driving situation in the near future.

  Here, when the traveling state predicting unit 25 predicts that the vehicle is to turn left or turn left, the acceleration detecting unit 21 detects leftward acceleration, so that the display image generating unit 26 is based on this information. For example, as shown in FIG. 2A, a person image indicating that the vehicle is moving in the left direction is generated, and displayed or blinked on the entire screen or a part of the screen by the display means 27 to alert the occupant.

  On the other hand, when it is predicted that the vehicle will turn right or turn right, for example, an image indicating that the vehicle is moving right as shown in FIG. indicate.

  Specifically, for example, FIG. 6 shows a sequence diagram when a route is set as shown in FIG. In addition, A point and C point in FIG. 5 mean that it is the point before B point and D point which are intersections, respectively, and the distance of A point and B point and C point and D point is, for example, It is assumed that the position is a fixed distance such as 30 m, a position before a certain time by speed, and the like.

  As shown in FIG. 2, when the display image generating means 26 generates an image for notifying the traveling direction, it is appropriate to use the data flow as shown in FIG. That is, the traveling state prediction unit 25 predicts that the point B is turned right at the point A, and outputs the prediction information to the display image generation unit 26 (S1).

  At this time, the display image generation means 26 generates an image as shown in FIG. 2B and outputs it to the display means 27, for example, in order to notify the right turn (S2). The same applies to the points C and D, and the information predicted by the traveling state prediction unit 25 to turn left is output (S3), and the display image generation unit 26 generates, for example, an image as shown in FIG. It outputs to the display means 27 (S4).

  As described above, when it is predicted in advance that a right turn or a left turn will be performed at the point A or the point C, an image that prompts the occupant to turn right or left is displayed on the display unit 27 as shown in FIG.

  On the other hand, as shown in FIG. 3, when the display image generating means 26 generates an image in which the display position of the image is shifted on the screen, it is appropriate to use the data flow as shown in FIG. .

  That is, it is predicted that the traveling state prediction unit 25 turns right at the point B at the point A, and the prediction information is output to the display image generation unit 26 (S11). The display image generation unit 26 generates an image as shown in FIG. 3B, for example, so as to correspond to the acceleration in the left direction when turning right, and outputs the image to the display unit 27 when the vehicle passes through the point B. (S12).

  The same applies to the points C and D. The information predicted by the traveling state prediction unit 25 to turn left at the point C is output (S13), the display image generation unit 26 generates an image, and the vehicle passes the point D. Sometimes an image is output to the display means 27 (S14).

  In this way, it is predicted in advance that a right turn or a left turn will be made at point A or point C, and during the actual right or left turn at point B or D, an image is displayed as shown in FIG. An image whose position is shifted on the screen is displayed on the display means 27.

  The traveling state prediction means 25 may predict the traveling state based on the vehicle speed information before passing the intersection (point A or point C in FIG. 5) and the road shape of the intersection on the route.

  In addition, if the driving situation is predicted before passing the intersection (point A or point C in FIG. 5) and actually passes through the intersection (point B or point D in FIG. 5) and differs from the prediction, a display image is generated. The means 26 may generate an image based on information on the acceleration or vehicle speed currently being measured, and the image generated by prediction may be used as a measure of the acceleration when acceleration starts to be applied.

  The method for generating an image based on the acceleration information currently being measured is the same as in the first embodiment. Further, the traveling state prediction means 25 predicts the degree of deceleration immediately before the intersection or the degree of acceleration immediately after the intersection based on the road shape information obtained from the route data held by the route guidance means 24. Alternatively, the display image generation unit 26 may generate an image according to the acceleration / deceleration prediction of the traveling state prediction unit 25.

  Moreover, the vehicle-mounted camera which images the front of a vehicle may be provided and the driving | running | working condition estimation means 25 may estimate a driving | running | working condition based on the image | video which the vehicle-mounted camera imaged. In this case, the vehicle-mounted camera may be installed in place of the traveling state detecting unit 22 or the route guiding unit 24, or may be installed together with the traveling state detecting unit 22 and the route guiding unit 24.

  In addition to the information on the direction of acceleration detected by the acceleration detecting means 21, information on the magnitude of acceleration may be used. In this case, the display image generating means 26 is a different image depending on the direction and magnitude of the acceleration. Is generated.

  Further, the acceleration detection means 21 may detect the acceleration in the front-rear direction of the vehicle. In this case, the display image generation means 26 generates an image corresponding to the direction and magnitude of the acceleration in the front-rear and left-right directions. The display image generation unit 26 may generate an image corresponding to the direction and magnitude of the acceleration in advance and store it in the storage unit.

  As described above, in the present embodiment, the driving situation such as turning left or right or turning of the vehicle is detected based on the current position information, the future driving situation is predicted based on the driving situation and the route information, and the prediction information Since the situation exerted on the occupant's body is displayed based on the above, when the lateral acceleration is applied to the vehicle, the occupant can cope with this in advance, and can comfortably view the video.

  In particular, when an occupant such as a child concentrates on the image displayed on the display device 27 and is not looking at the scenery outside the vehicle, the degree of influence due to acceleration in the left-right direction of the vehicle is large. The video can be viewed more comfortably.

  Further, when the acceleration detecting means 21 outputs the acceleration applied to the vehicle as acceleration information, the traveling condition detecting means 22 transfers the acceleration information to the traveling condition predicting means 25, and the traveling condition predicting means 25 receives the acceleration information and the prediction information. Therefore, the traveling state of the vehicle can be reliably predicted in advance based on the acceleration information and the prediction information.

  Further, when the acceleration detecting means 21 outputs the acceleration applied to the vehicle as acceleration information, the traveling condition detecting means 22 transfers the acceleration information to the traveling condition predicting means 25, and the traveling condition predicting means 25 makes the vehicle turn right or left. Predictive information is output before starting the turn, and when the vehicle is turning left or right or turning, the vehicle's driving status is detected based on the currently obtained acceleration information. Alternatively, you can output prediction information before starting a turn, or view an image that informs the passengers of the situation before the vehicle makes a right or left turn or turn, or during a right or left turn or turn The video on the display device can be viewed comfortably.

  In addition, since the display position of the image on the display means 27 is shifted upward, downward, left, and right according to the driving condition detected by the driving condition detection means 22, Alternatively, if the display position of the image on the display means 27 is shifted up, down, left, and right during turning, acceleration, and deceleration, the traveling situation can be made visible to the occupant in real time.

  Further, if the display of the image on the display means 27 is converted into right rotation, left rotation, enlargement, reduction, trapezoid, etc. according to the driving condition detected by the driving condition detection means 22, the driving condition is displayed. The passenger can be seen in real time.

  Also in the present embodiment, since the operation setting unit 29 for enabling or disabling the operation of the display image generating unit 26 is provided, the operation setting unit 29 performs an operation for disabling the display image generating unit 26. Thus, the above-described image display control can be prevented from being performed.

  As described above, the on-vehicle display control device according to the present invention is a case where the position of the eyes of the vehicle occupant moves due to a change in the vehicle traveling condition such as turning left / right, turning, sudden acceleration / braking, etc. However, an on-vehicle display control device or the like that has the effect of being able to comfortably visually recognize the image on the display device, can be provided on the vehicle, and can provide the vehicle occupant with the image according to the traveling state of the vehicle.
