  The right side camera 5 is provided below the right side mirror 7 and is arranged so that the right side of the vehicle 1 can be imaged including the road surface.

  FIG. 2 is a block diagram showing an electrical configuration of a main part (vehicle peripheral display device) of the vehicle 1.

  A display 11 with a touch panel is disposed in the vehicle interior of the vehicle 1. The display 11 with a touch panel has, for example, a configuration in which a pressure-sensitive or capacitive transparent film switch is attached to a liquid crystal display, and is connected to a navigation device or an audio device to display various information such as navigation information and music information. It is provided as a multi-purpose touch panel.

  In addition, the vehicle 1 is provided with an ECU (electronic control unit) 12. The ECU 12 includes a CPU and a memory. A front camera 2, a rear camera 3, a left side camera 4, a right side camera 5, and a display 11 with a touch panel are electrically connected to the ECU 12.

  FIG. 3 is a flowchart showing a flow of the overhead view image display process executed by the ECU 12. FIG. 4A is a diagram illustrating an example of an overhead image displayed on the display 11 with the touch panel, and FIG. 4B is a diagram illustrating an example of an enlarged image in which a part of the overhead image is displayed in an enlarged manner.

  For example, when a top view switch displayed on the display 11 with a touch panel is pressed, an overhead image as shown in FIG. 4A is displayed on the display 11 with a touch panel (step S1). The bird's-eye view image is an image showing a state in which the entire vehicle 1 and the road surface around it are seen from above. The overhead view image is converted into an image obtained by projecting each image photographed by the front camera 2, the rear camera 3, the left side camera 4, and the right side camera 5 onto a plane from above by image processing, and these images are displayed around the image of the vehicle 1. Are generated by mapping the projected images.

  Thereafter, it is determined whether or not a slide operation (flick) for enlarging and displaying a part of the overhead image on the touch panel display 11 has been performed (step S2). The driver or the like moves the image of the vehicle 1 on the display 11 with the touch panel so as to move the image of the vehicle 1 while pressing the image of the vehicle 1 included in the overhead view image displayed on the display 11 with the touch panel with fingers or the like. By sliding in any direction, it is possible to enlarge and display a part of the overhead view image corresponding to the direction of the slide operation (slide direction).

  When a slide operation is performed on the display 11 with the touch panel (YES in step S2), the slide direction is specified (step S3). For example, the sliding direction is specified by approximating any one of the eight directions of upper, lower, left, right, upper left, upper right, lower left, and lower right.

  Then, the end portion of the vehicle 1 in the direction opposite to the sliding direction and the overhead view image around the end portion are enlarged and displayed on the display 11 with the touch panel (step S4). For example, when a slide operation is performed so as to move the image of the vehicle 1 to the lower right, as shown in FIG. 4B, the overhead view image of the left front end of the vehicle 1 and its surroundings is enlarged on the display 11 with the touch panel. Is displayed.

  After the enlarged image is displayed, it is determined whether or not a touch operation (pressing operation for a short time) has been performed on the display 11 with the touch panel with fingers (step S5).

  If a touch operation is performed during the display of the enlarged image (YES in step S5), the whole vehicle 1 and its surrounding bird's-eye view are displayed again on the display 11 with the touch panel (step S6).

  Then, it is determined whether or not a display end condition for ending the display of the whole vehicle 1 and its surrounding bird's-eye view image or enlarged image is satisfied (step S7). The display end condition may be, for example, a pressing operation of an end switch displayed on the display 11 with the touch panel, or may be that the vehicle 1 has advanced over a predetermined time at a predetermined speed or higher.

  When the touch operation is not performed (NO in step S5), it is determined whether the display end condition is satisfied while the enlarged image is displayed on the display 11 with the touch panel (step S6 is skipped) ( Step S7).

  In addition, after the display of the bird's-eye view of the entire vehicle 1 and its surroundings, when the slide operation is not performed (NO in step S2), the bird's-eye view of the entire vehicle 1 and its surroundings are displayed on the display 11 with the touch panel. Whether or not the display end condition is satisfied is determined (step S7).

  If the display end condition is not satisfied (NO in step S7), it is determined whether or not the entire vehicle 1 and its surrounding bird's-eye view images are displayed on the display 11 with the touch panel (step S8).

  When the whole vehicle 1 and its surrounding bird's-eye view image are displayed on the display 11 with the touch panel (YES in step S8), it is determined again whether or not a slide operation has been performed (step S2), and the above-described step S2 The subsequent processing is executed again.

  On the other hand, when an enlarged image is displayed on the display 11 with the touch panel (NO in step S8), it is determined again whether or not a touch operation has been performed (step S5), and the processes after step S5 described above are executed again. Is done.

  When the display end condition is satisfied during the display of the whole vehicle 1 and its surrounding bird's-eye view image or enlarged image, the image displayed on the display 11 with the touch panel is erased (step S9), and the bird's-eye view image display process is performed. Is terminated.

  As described above, while pressing the image of the vehicle 1 included in the overhead image displayed on the display 11 with the touch panel with a finger or the like, the finger or the like is moved on the display 11 with the touch panel so as to move the image of the vehicle 1. By sliding in any direction, it is possible to input the sliding direction (moving direction). When the slide direction is input, an overhead image including the end of the vehicle 1 in the direction opposite to the input slide direction and the periphery of the end is enlarged and displayed on the display 11 with the touch panel.

  Therefore, an enlarged image including a part of the vehicle 1 can be displayed on the display 11 with the touch panel by an intuitive and easy-to-understand operation.

  As mentioned above, although one Embodiment of this invention was described, this invention can also be implemented with another form.

  For example, switching from the bird's-eye view image of the entire vehicle 1 and its surroundings to an enlarged image may be performed instantaneously or may be performed continuously. That is, in response to a slide operation, the whole vehicle 1 and its surroundings may be instantaneously switched from a bird's-eye view image to an enlarged image, and the enlargement rate changes according to the amount of slide operation with the slide operation. Thus, the bird's-eye view image of the entire vehicle 1 and its surroundings may be enlarged.

  Also, the sliding direction is specified as any one of the eight directions of upper, lower, left, right, upper left, upper right, lower left, and lower right. The number of specified directions is 7 The following may be sufficient and nine or more may be sufficient.

  In addition, it is possible to input the sliding direction (moving direction) by sliding a finger or the like on the display 11 with the touch panel. For example, a touch operation with a finger or the like at a position away from the center of the image of the vehicle 1 is performed. By doing so, the direction of the position of the touch operation with respect to the center of the image of the vehicle 1 may be input as the slide direction.

  In order to assist this input operation, an arrow image indicating a plurality of directions may be displayed around the center of the image of the vehicle 1. In this case, when any of the arrow images is touched, the direction of the arrow may be input as the slide direction.

  Further, in the above-described embodiment, an example in which the display 11 with a touch panel is adopted and the means for inputting the sliding direction (moving direction) is configured by a transparent film switch on the liquid crystal display is taken up. However, the present invention is not limited to this, and instead of the display 11 with the touch panel, a joystick or the like for inputting a moving direction may be provided in the vehicle interior together with a liquid crystal display without a transparent film switch.

  In addition, various design changes can be made to the above-described configuration within the scope of the matters described in the claims.
