  The method and procedure for acquiring the operation support information from the driving condition condition storage unit 11 are the same as the method and procedure for acquiring the operation support content information from the driving condition condition storage unit 11 by the operation support content information acquiring unit 16. Description is omitted because it exists.

  When the process of (B) is performed: The operation support information acquired by performing the process of (B) is usually dynamic operation support information, but may be static operation support information. In this case, the driving situation condition storage unit 11 stores one or more driving situation conditions associated with the operation support content information. And the operation assistance information acquisition part 17 produces operation assistance information normally according to the operation assistance content information which the operation assistance content information acquisition part 16 acquired. Specifically, the operation support information acquisition unit 17 creates operation support content information according to the content indicated by the operation support content information. At this time, the operation support information acquisition unit 17 normally uses the driving status information used when the operation support content information acquisition unit 16 acquires the operation support content information, but may not use it.

  For example, it is assumed that the operation support content information is "handle angle: image". The said operation assistance content information means producing the image which shows the angle which turns a steering wheel. In addition, it is assumed that the driving condition information used when acquiring the operation support content information is road shape information indicating the shape of the road corresponding to the current position. In such a case, the operation support information acquisition unit 17 calculates the angle of the tire using, for example, the curvature of the road indicated by the road shape information, and calculates the angle of turning the steering wheel using the angle of the tire. And the operation assistance information acquisition part 17 produces the image which shows the angle which turns the said handle using the angle which turns the said handle.

  Further, for example, it is assumed that the operation support content information is "steering wheel angle, vehicle surroundings: image". The said operation assistance content information means producing a handle operation image and a surrounding positional relationship image. In such a case, the operation support information acquisition unit 17 first acquires an ambient image that is an image around the vehicle. There is no limitation on the method and procedure of acquiring the surrounding image, the direction of the surrounding image with respect to the host vehicle, and the like. It is preferable that the ambient image is usually acquired by a so-called on-vehicle camera. In addition, it is preferable that the surrounding image is usually four images of the front, the rear, the left, and the right of the vehicle.

  And the operation assistance information acquisition part 17 calculates the angle of the own vehicle with respect to the direction to want to advance using a surrounding image. For example, in the case of parking, the direction in which the user wants to move is a direction in which there is a space where no obstacle exists, such as a parking position. In addition, the situation at the time of driving in the case of creating the surrounding positional relationship image is usually a situation in which the user is moving backward while operating the steering wheel. Therefore, the operation support information acquisition unit 17 performs image processing on the surrounding image indicating the rear, and calculates the angle of the vehicle relative to the direction in which the user wants to proceed.

  And the operation assistance information acquisition part 17 calculates the angle of a tire using the angle of the own vehicle with respect to the direction to want to advance. The angle of the tire is the angle of the tire to travel in the direction in which it wants to travel. And the operation assistance information acquisition part 17 calculates the angle which turns a steering wheel using the angle of the said tire, and produces the image which shows the angle which turns the said steering wheel using the angle which turns the said steering wheel.

  Then, the operation support information acquisition unit 17 creates an ambient positional relationship image using the ambient image. For example, when the surrounding image is the above four images, for example, the operation support information acquiring unit 17 corrects the distortion of each of the images, combines the four surrounding images into one image, and Create a positional relationship image. Further, for example, when the surrounding image is one image, the operation support information acquiring unit 17 corrects distortion of each of the images, for example, and creates a surrounding positional relationship image. Note that there is no limitation on the method or procedure for creating an ambient positional relationship image using the ambient image. As a technique for creating an ambient positional relationship image, for example, there is an around view monitor (http://www.nissan-global.com/JP/TECHNOLOGY/OVERVIEW/avm.html).

  Note that there is no limitation on the method or procedure for calculating the above-mentioned "angle of turning the steering wheel". Usually, the angle at which the steering wheel is turned does not coincide with the angle at which the tire moves by turning the steering wheel. Therefore, the operation support information acquisition unit 17 holds in advance a calculation formula for calculating an angle for turning the steering wheel using, for example, the angle of the tire, and calculates the angle for turning the steering wheel using the calculation formula. .

  Further, the method or procedure for creating the above-mentioned "image showing the angle of turning the steering wheel" is not limited. In general, the appearance of the image showing the turning angle of the handle usually does not change each time the image showing the turning angle of the handle is created. Therefore, the operation support information acquisition unit 17 holds, for example, information indicating a procedure for creating an image indicating an angle of turning the handle, and uses the information to create an image indicating the angle of turning the handle. The “information” is, for example, a so-called function or a so-called model. The function has, for example, an argument that substitutes an angle for turning the handle. The function may be, for example, operation support content information acquired by the operation support content information acquisition unit 16.

  In addition, when acquiring the operation support information by performing the process of (B), the operation support information acquisition unit 17 generally operates the operation support information each time the operation support content information acquisition unit 16 acquires the operation support content information. Create This means that, in response to a change in the driving situation, operation support information suitable for the driving situation is created. Thus, the operation support information changes in accordance with the driving situation.

  The output unit 18 outputs the operation support information acquired by the operation support information acquisition unit 17. The output operation support information is preferably transmitted normally. Therefore, the output is usually display on a transmissive liquid crystal panel or the like, projection on a transparent panel or the like using a liquid crystal projector, hologram formation, or the like. Also, the output may be, for example, a concept including transmission to an external device, accumulation in a recording medium, delivery of a processing result to another processing device, another program, or the like. In this case, the transmitted or accumulated operation support information is finally presented to the user. At this time, it is preferable that the operation support information is usually transmitted.

  In addition, the output unit 18 normally ends the output when the condition related to the operation support information being output satisfies a predetermined condition (hereinafter, an output end condition as appropriate). The “state relating to the output operation support information” is, for example, an elapsed time since the output or whether new operation support information has been acquired. Further, the output end condition is that an elapsed time after the output is equal to or longer than a predetermined time, that new operation support information has been acquired, or the like. That is, for example, when a time greater than or equal to a predetermined time has elapsed since the output of the operation support information, the output unit 18 ends the output of the output operation support information. Also, for example, when new operation support information is acquired, the output unit 18 ends the output of the output operation support information.

  In addition, the output unit 18 normally outputs the operation support information to a position where the amount of movement of the driver's line of sight satisfies the predetermined condition (hereinafter, the line of sight movement amount condition as appropriate). The amount of movement of the line of sight is usually the angle at which the line of sight moves up, down, left, and right. That is, the eye movement amount condition is, for example, that the angle when moving up and down the driver's eye is greater than or equal to the first threshold and less than or equal to the second threshold; More than the first threshold and less than the second threshold. The output unit 18 may normally output the operation support information near the line of sight of the driver at the time of driving. In other words, in general, the output unit 18 only needs to be able to output the operation support information within a predetermined range within the field of view of the driver.

  Further, in the above-mentioned “output to a position where the amount of movement of the driver's line of sight meets the line of sight movement amount decreases,” for example, a panel which is an output destination of the operation support information satisfies the line of sight movement amount condition. Including being attached to In addition, the position of the operation support information to be output may be a position satisfying the sight line movement amount as a result.

  Also, for example, when the operation support information is relative mechanism position related information, the output unit 18 outputs the operation support information to a position that satisfies the eye movement amount. Also, for example, when the operation support information is absolute mechanism position related information, the output unit 18 outputs the mechanism information of the operation support information to the position indicated by the mechanism information output position information of the operation support information. Do. As a result, the output unit 18 outputs the operation support information so that the relative position of the mechanism can be known. Also, for example, when the operation support information is dynamic operation support information, the output unit 18 outputs the operation support information to a position that satisfies the eye movement amount.

  The output unit 18 may or may not be considered to include an output device such as a display or a speaker. The output unit 18 can be realized by driver software of an output device, or driver software of an output device and an output device.

  The driving condition storage unit 11, the map information storage unit 12, and the route information storage unit 13 are preferably non-volatile recording media, but may be realized by volatile recording media. Moreover, the process in which predetermined | prescribed information is memorize | stored in the driving | running condition condition storage part 11 grade | etc., Does not matter. For example, the predetermined information may be stored in the operating condition storage unit 11 or the like via a recording medium, a communication line, an input device, or the like.

  In addition, the operation support content information acquisition unit 16 and the operation support information acquisition unit 17 can be usually realized by an MPU, a memory, or the like. In addition, the processing procedure of the operation support content information acquisition unit 16 or the like is usually realized by software, and the software is stored in a storage medium such as a ROM. The operation support content information acquisition unit 16 and the like may be realized by hardware (dedicated circuit).

  Next, the overall operation of the in-vehicle apparatus 1 will be described using a flowchart. The i-th information in the predetermined information is described as "information [i]". FIG. 2 is a flowchart showing the overall operation of the in-vehicle apparatus 1. In FIG. 2, it is assumed that m driving condition conditions are stored in the driving condition condition storage unit 11.

After that, the driving status information acquiring unit 15 normally continues to periodically acquire the driving status information until the power of the in-vehicle device 1 is turned off.

  (Step S205) In step S204, the operation support information acquisition unit 17 determines whether the driving condition information acquiring unit 15 has acquired driving condition information. If it has been acquired, the process proceeds to step S206. If not, the process returns to step S205.

  (Step S206) The operation support information acquisition unit 17 determines whether the driving support condition storage unit 11 stores the operation support information.

  (Step S211) The operation support information acquisition unit 17 increments i by one. Then, the process returns to step S208.

  (Step S212) The operation support content information acquisition unit 16 sets 1 to the counter i.

  (Step S216) The operation support content information acquisition unit 16 increments i by one. Then, the process returns to step S213.

  (Step S217) The operation assistance information acquisition part 17 produces the operation assistance information according to the operation assistance content information acquired by step S216.

  (Step S218) The output unit 18 outputs the operation support information acquired in step S209 or the operation support information generated in step S217.

  (Step S219) The in-vehicle device 1 determines whether a receiving unit (not shown) has received an instruction to turn off the power. If it is accepted, the process proceeds to step S220. If not, the process returns to step S205.

  (Step S220) The in-vehicle device 1 performs a power off process. Then, the process returns to step S201.

  In the flowchart of FIG. 2, the process may be ended by an interruption of power off or process end.

  Further, in the case of creating a handle operation image in step S217 of the flowchart of FIG. 2, the flowchart showing the process of creating the handle operation image is shown in FIG.

  (Step S301) The operation support information acquisition unit 17 determines whether the driving condition information determined to match the driving condition condition [i] in step S213 is road shape information. When it is road shape information, it progresses to step S304, and when that is not right, it progresses to step S302.

  (Step S302) The operation support information acquisition unit 17 acquires road shape information that is determined to match the driving condition [i] in step S213.

  (Step S303) The operation support information acquisition unit 17 acquires current map information, which is map information corresponding to the current position. The current map information is information indicating a map within a predetermined distance range from the current position.

  (Step S307) The operation support information acquisition unit 17 uses the angle for turning the steering wheel calculated in step S306 to create a steering wheel operation image indicating the angle for turning the steering wheel.

  Further, in the case where the handle operation image and the surrounding positional relationship image are created in step S217 of the flowchart of FIG. 2, the flowchart showing the processing for creating the steering wheel operation image and the surrounding positional relationship image is FIG.

  (Step S401) The operation support information acquisition unit 17 acquires a surrounding image.

  (Step S407) The operation support information acquisition unit 17 creates a surrounding positional relationship image using the corrected surrounding image acquired in step S406.

(Concrete example)
Next, a specific example of the operation of the in-vehicle apparatus 1 will be described. In the present specific example, it is assumed that the current position information acquisition unit 14 and the driving condition information acquisition unit 15 periodically acquire current position information and driving condition information.

(Example 1)
In the present example, an example will be described in which the operation support information associated with the driving condition is acquired and the operation support information is output. In the present example, it is assumed that the driving situation conditions shown in FIG. 5 are stored in the driving situation condition storage unit 11. The driving condition condition (item name: condition) corresponds to an ID for uniquely identifying a record and operation support information (item name: operation support).

  First, it is assumed that the driver gets into a car equipped with the in-vehicle device 1 and turns the engine switch from "OFF" to "ON" to start the engine. Then, the operating condition information acquiring unit 15 acquires operating condition information “engine switch: ON” indicating that the engine switch is in the “ON” position.

  Next, the operation support information acquiring unit 17 determines which of the driving condition conditions of FIG. 5 the driving condition information “engine switch: ON” acquired by the driving condition information acquiring unit 15 matches. Then, the operation support information acquisition unit 17 determines that the driving condition information matches the driving condition condition “(engine switch = ACCor ON)” of “ID = 011” in FIG. 5. The operating condition means that the engine switch is in the "ACC" or "ON" position.

Next, the operation support information acquisition unit 17 acquires the "ID = 011" operation support information "Peda l .jpg" in FIG. The operation support information is an identifier (file name) for identifying an image, and the operation support information acquisition unit 17 actually acquires the image identified by the identifier from the driving condition condition storage unit 11. Moreover, the said image is an image which shows the relative positional relationship of an accelerator pedal and a brake pedal.

  Next, the output unit 18 outputs the image identified by "pedal. Jpg" to the windshield near the front of the driver's line of sight. The state at this time is, for example, FIG. In FIG. 6, the image in the area of “A” surrounded by a broken line is the output image.

  In a general automobile, an accelerator pedal and a brake pedal are usually installed in the vicinity of the right foot when seated in the driver's seat. Also, the two pedals are normally the accelerator pedal on the right side and the brake pedal on the left side. Therefore, as shown in FIG. 6, the relative positional relationship between the accelerator pedal and the brake pedal is shown by outputting the image which is the operation support information.

  Further, for example, it is assumed that a driver sets a route to a destination and a car is traveling on the route. In addition, it is assumed that the driving condition information acquiring unit 15 acquires the driving condition information “branch point distance: 200 m” indicating the distance to the nearest branch point and the driving condition information “fine” indicating the weather during the traveling.

  Next, in the same manner as described above, the operation support information acquisition unit 17 determines which of the driving condition conditions of FIG. 5 the two pieces of driving condition information acquired by the driving condition information acquiring unit 15 match. It is determined that the driving condition condition “(branch point distance ≦ 300 m) or (weather = rain)” of “ID = 012” in FIG. 5 is met. The said driving | running condition conditions mean that the distance to the nearest branch point is 300 m or less, or that the weather is rain.

  Next, the operation support information acquisition unit 17 acquires the operation support information “lever. Jpg” of “ID = 012” in FIG. The image identified by the identifier is an image showing the relative positional relationship between the winker lever and the wiper lever.

  Next, the output unit 18 outputs the image identified by "lever. Jpg" to the windshield near the front of the driver's line of sight. A state at this time is, for example, FIG. In FIG. 7, the image in the area of “B” surrounded by a broken line is the output image.

  In a general automobile, a turn signal lever is usually provided on the right side of the steering column, and a wiper lever is provided on the left side of the steering column. Therefore, as shown in FIG. 7, the relative positional relationship between the winker lever and the wiper lever is shown by outputting an image which is the operation support information.

(Example 2)
In the present example, an example will be described in which the operation support content information associated with the driving condition is acquired, the operation support information corresponding to the operation support content information is created, and the operation support information is output. In the present example, it is assumed that the driving situation conditions shown in FIG. 8 are stored in the driving situation condition storage unit 11. The said driving | running condition conditions (item name: conditions) are matched with ID for specifying a record uniquely, and operation assistance content information (item name: assistance content).

  First, similarly to Example 1, it is assumed that the driving condition information acquiring unit 15 acquires road shape information indicating the shape of the road corresponding to the current position as driving condition information at a certain timing. The said road shape information shall have the name "curve" which shows the shape of a road, and the curvature "1/1000" which shows the shape of a road.

  Next, as in the operation support information acquisition unit 17 of Example 1, the operation support information acquisition unit 16 acquires the operation condition information “curve” acquired by the driving condition information acquisition unit 15 as “ID = 011” in FIG. It is determined that the driving condition condition “(road shape = curve)” is satisfied. The said driving | running condition conditions mean that the shape of the road corresponding to a present position is a curve.

  Next, the operation support content information acquisition unit 16 acquires the operation support content information “handle angle: image” of “ID = 011” in FIG. 8. The operation support content information indicates that the angle at which the steering wheel is turned is indicated by an image. In other words, the operation support content information means creating a handle operation image.

  Next, the operation support information acquisition unit 17 calculates the tire angle with respect to the center line of the vehicle for traveling on the road using the curvature "1/1000" indicating the shape of the road included in the driving condition information. Do.

  Next, the operation support information acquisition unit 17 uses the calculated tire angle to calculate the steering wheel angle that is actually turned because the actual tire angle becomes the calculated tire angle. Here, it is assumed that the operation support information acquisition unit 17 has calculated an angle “+ 30 °” in which the steering wheel is turned. The said angle means rotating "30 degrees" rightward. That is, the angle indicates whether it is turned clockwise or counterclockwise by a code.

  Next, the operation support information acquisition unit 17 creates a steering wheel operation image indicating the angle by using the calculated angle “30 °” of turning the steering wheel. The operation support information acquisition unit 17 holds, for example, an image shown in FIG. 9 in advance. The said image is a model of a handle operation image. In addition, a scale is drawn on the image in steps of 15 °. Therefore, the operation support information acquisition unit 17 copies the image of the template in FIG. 9 and fills the scale of 30 ° in the right direction of the copied image to create, for example, a handle operation image as shown in FIG.

  Next, the output unit 18 outputs the handle operation image of FIG. 10 at the same position as the operation support information (image) output in FIGS. 6 and 7.

  Also, for example, it is assumed that as the traveling continues, the curve of the road on which the vehicle is traveling has gradually become stronger. At this time, the driving condition information acquisition unit 15 periodically acquires road shape information. In addition, the operation support content information acquisition unit 16 acquires the operation support content information “steering wheel angle: image” of “ID = 011” in FIG. 8 every time the road shape information is acquired. Further, each time the operation support information acquisition unit 17 acquires the operation support content information, similarly to the above, the steering operation image is created using the road shape information used to acquire the operation support content information. The operation support information acquisition unit 17 sequentially calculates, for example, angles “32 °”, “33 °”, “35 °” and the like that turn the steering wheel, and sequentially creates a steering wheel operation image indicating the angle. Further, the output unit 18 outputs the handle operation image in the same manner as described above each time the handle operation image is generated. In other words, this is equivalent to the output of a moving image that indicates the angle at which the steering wheel is turned according to the degree of curvature of the road on which the vehicle is traveling. Further, it can be said that the appearance of the output is, for example, the same as the appearance of the speed meter changing according to the change of the speed.

  Further, for example, at a certain timing, the driving status information acquisition unit 15 displays driving status information “select lever: R” indicating the status of the select lever, and driving status information “parking lot” indicating the location corresponding to the current position. Suppose you get

  Next, in the same manner as described above, the operation support content information acquisition unit 16 determines which of the driving condition conditions shown in FIG. 8 the two pieces of driving condition information acquired by the driving condition information acquiring unit 15 match. It is determined that the driving condition condition “(select lever = R) & (location = parking lot)” of “ID = 013” in FIG. 8 is met. The said driving | running condition condition is a state in which a selection lever is in the position of "R", and means that the place corresponding to the present position is a parking lot.

  Next, the operation support content information acquisition unit 16 acquires the operation support content information “steering wheel angle, vehicle surroundings: image” of “ID = 013” in FIG. 8. The said operation assistance content information means showing each with the image of the angle which turns a steering wheel, and the positional relationship of a self-vehicle and a surrounding obstacle. In other words, the operation support content information means creating a handle operation image and a surrounding positional relationship image.

  Next, the operation support information acquisition unit 17 acquires four surrounding images of front, rear, left, and right. Then, the image processing on the rear surrounding image is performed, and the angle of the vehicle with respect to the direction to be advanced is calculated.

  Next, the operation support information acquisition unit 17 uses the calculated angle of the vehicle to calculate the angle of the tire with respect to the center line of the vehicle in order to move in the direction to proceed.

  Next, the operation support information acquisition unit 17 uses the calculated tire angle to calculate the steering wheel angle that is actually turned because the actual tire angle becomes the calculated tire angle. Here, it is assumed that the operation support information acquisition unit 17 has calculated an angle “+ 30 °” in which the steering wheel is turned.

  Next, in the same manner as in Example 1, the operation support information acquisition unit 17 creates a steering wheel operation image indicating the angle by using the calculated angle “30 °” of turning the steering wheel. The said handle operation image is FIG. 10, for example.

  Next, the operation support information acquisition unit 17 performs image processing on each of the four surrounding images to correct distortion. The correction is, for example, processing for returning the curve to a straight line when what is actually a straight line appears in the curve due to the influence of the camera lens. Then, the operation support information acquisition unit 17 combines the four surrounding images on the basis of an obstacle or the like common to the four surrounding images, and creates one image. At this time, the operation support information acquisition unit 17 holds the image of the vehicle in advance, and combines the images of the vehicle. The combined image is a surrounding positional relationship image, and is, for example, FIG.

  Next, the output unit 18 outputs the handle operation image of FIG. 10 and the peripheral positional relationship image of FIG. 11 at the same position as the operation support information (image) output in FIGS. 6 and 7. At this time, the output unit 18 outputs the two images, for example, so that the handle operation image and the surrounding positional relationship image are arranged vertically.

  As described above, according to the in-vehicle device 1 of the present embodiment, the operation of the operation mechanism is performed by outputting information determined in advance according to the driving situation, information generated according to the driving situation, and the like. Can help.

  In each of the above embodiments, it goes without saying that two or more communication means existing in one device may be physically realized by one medium.
