no. 1 Embodiment approach

[0053] Next, an embodiment of a parking assist device according to the present invention will be described with reference to FIGS. 1 to 14 . FIG. 1 is a block diagram illustrating the configuration of a parking assist system 1 .

[0054] As shown in FIG. 1 , a parking assistance system 1 has a control device 2 as a parking assistance device. The control device 2 has a control unit 3 , a main memory 4 and a ROM 5 . The control unit 3 has a CPU (not shown) and the like, and performs main control of various processes in accordance with various programs such as a parking assist program stored in the ROM 5 . The main memory 4 temporarily stores calculation results of the control unit 3 and also stores various variables, flags, and the like used for parking assistance.

[0055] Vehicle image data 5 a is stored in ROM 5 . The vehicle image data 5 a is data for outputting an image of a vehicle (see FIG. 3 ) in which the parking assist system 1 is installed to the display 8 as a dis...

no. 2 Embodiment approach

[0099] Next, a second embodiment of the present invention will be described with reference to FIGS. 15 and 16 . In addition, since the structure of the second embodiment is changed only from the straight guide line St of the first embodiment, a detailed description of the same parts will be omitted.

[0100] In the drawing processing of the curve guide line Rv and the straight guide line St (see FIG. 11 ) in the second embodiment, the same processing as that in the first embodiment is performed in steps S5-1 to S5-6. Then, in step S5-7, the image processor 15 does not draw the straight guide line St, but draws the straight guide frame F serving as the expected position indicator. The straight-ahead guide frame F represents the external shape of the vehicle at a position where the vehicle C is parallel to the white line approximation expression Sg.

[0101] The straight guide frame F will be described with reference to FIG. 15 . The straight-ahead guide frame F is composed of...

Abstract

In a control device of a parking assist system for outputting a synthesized image (52) of the periphery of a vehicle, which is formed into a bird's-eye view image using image data, to a display, turning guide lines based on the steering angle of the vehicle and straight driving guide lines (St) along which the vehicle drives in a straight line after turning in accordance with the turning guide lines (Rv) are output to the display together with the synthesized image (52).

Description

technical field [0001] The invention relates to a parking assistance method and a parking assistance device. Background technique [0002] Conventionally, an on-vehicle device that displays images captured by an on-vehicle camera on a display is known. This device inputs video signals from an on-board camera installed at the rear of the vehicle, and outputs peripheral images based on the video signals together with guidance lines to a monitor placed near the driver's seat. [0003] Also, Patent Document 1 describes an image processing device that accumulates image data input from an on-vehicle camera during a parking operation, performs image processing using the accumulated image data, and displays a bird's-eye view image overlooking the surrounding area of ​​the vehicle. [0004] Furthermore, Patent Document 2 also proposes a device that not only displays a bird's-eye view image, but also superimposes an estimated trajectory corresponding to the current steering degree an...
