  However, in the above-described conventional parking assist device, since image recognition is used to recognize the parking target position, there is a problem that the amount of calculation of the CPU increases and the price of the entire system becomes expensive. . In addition, when image recognition is used, when finely adjusting the parking frame detected by image recognition, the work of continuously pressing the screen or button occurs, so it takes a lot of time to specify the parking target frame. There was also a problem of end. Further, when parking in a parking lot where no white line is drawn, it is impossible to perform parking support by image recognition.

  Therefore, the present invention has been proposed in view of the above-described circumstances, and provides a parking assistance device capable of configuring a system at low cost by presenting a parking target position to a driver without using image recognition. An object is to provide such a method.

  The parking assist device according to the present invention superimposes and displays an image of a provisional parking target position prepared in advance on a bird's-eye view around the host vehicle, and places the temporary parking target position on the actual parking target position displayed in the bird's-eye view image. After the driver moves the vehicle so that the images match, the driver specifies the parking target position, and guides and controls the vehicle to the specified parking target position. To do.

  According to the parking assist device and the method thereof according to the present invention, an image of a provisional parking target position prepared in advance is displayed superimposed on the overhead video, and the temporary parking target is displayed at the actual parking target position displayed in the overhead video. Since the driver designates the parking target position after the driver moves the vehicle so that the images of the positions coincide with each other, the parking target position can be designated without using image recognition or the like. As a result, the calculation amount of the CPU can be reduced, and the system can be configured at low cost.

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

[First Embodiment]
[Configuration of parking assist device]
A first embodiment to which the present invention is applied will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the parking assistance apparatus according to the present embodiment.

  As shown in FIG. 1, the parking assistance device 1 according to the present embodiment receives an overhead image generation unit 2 that converts an image around the host vehicle to generate an overhead image, and an operation from the driver to the parking assistance device. Input unit 3, temporary parking target position setting unit 4 that performs setting for displaying an image of the temporary parking target position superimposed on the overhead view video, and image superposition that superimposes the image of the temporary parking target position on the overhead video Unit 5, a parking target position specifying unit 6 for specifying a parking target position by a driver, and a parking guidance control unit 7 for guiding and controlling the host vehicle to the specified parking target position. Cameras 8a to 8d for imaging, a display unit 9 for presenting an image to the driver, a steering angle sensor 10 for detecting an operation direction and an operation amount of the steering wheel, and an EPS motor 11 for driving the power steering are connected. .

  Here, the parking assistance device 1 described above can be realized by, for example, storing a parking assistance program in a ROM (Read Only Memory) (not shown) and executing the parking assistance program by the CPU.

  The input unit 3 is an interface unit that receives input from the driver. For example, by preparing two buttons and assigning one button as a selection button and the other button as a determination button, the input unit 3 responds to a prompt from the system side. It is formed so that the driver's intention can be expressed.

  The cameras 8a to 8d are imaging means for capturing images around the host vehicle, and acquire images that are used as an interface between the parking assistance device 1 and the driver. Here, FIG. 2 shows an example of the arrangement of the cameras 8a to 8d. As shown in FIG. 2, a camera 8a is arranged on the front grille of the vehicle 20, a camera 8d is arranged near the rear bumper, and cameras 8b and 8c are arranged below the left and right door mirrors. The cameras 8a to 8d can present a wider area to the driver by using a wide-angle camera with a wide viewing angle. The vehicle 20 is not limited to a passenger car, and may be a commercial vehicle or a truck. Further, the installation positions of the cameras 8a to 8d are not limited to the arrangement shown in FIG. 2, and for example, a form installed at four corners of the vehicle or a form installed on the roof may be adopted.

  The overhead view video generation unit 2 performs viewpoint conversion on the images captured by the cameras 8a to 8d to generate an overhead view video. The images captured by the cameras 8a to 8d are images with a viewpoint placed obliquely above, and by performing viewpoint conversion on the images, an image viewed from vertically above the ground can be obtained. Regarding the image conversion performed here, for example, “Masayasu Suzuki, Satoshi Chino, Teruhisa Takano, Development of a bird's-eye view system, Preprint of Academic Lectures of the Society of Automotive Engineers of Japan, 116-07 (2007-10), 17-22. Or the like.

  The temporary parking target position setting unit 4 prepares an image of the temporary parking target position that is the temporary parking target position in advance, and the temporary parking target position based on the driver's intention detection signal input by the input unit 3. Is set to superimpose the image on the overhead video. For example, the image of the temporary parking target position stored in memory or the like may be read in advance, or the size of the read temporary parking target position image may be changed, or the color or brightness may be changed. Or you may.

  The image superimposing unit 5 superimposes the image of the temporary parking target position on the overhead video around the host vehicle generated by the overhead video generating unit 2. The image superposition performed here can be performed using a superimposing method of computer graphics.

  The display unit 9 is a display unit for presenting the image obtained by the image superimposing unit 5 as visual information to the driver, and is a monitor of a car navigation system, for example.

  The parking target position specifying unit 6 is provided in the input unit 3, and after the host vehicle is moved so that the image of the temporary parking target position matches the actual parking target position displayed in the overhead view video. The driver receives an input for designating the temporary parking target position corresponding to the actual parking target position as the parking target position. Further, the parking target position designated here is transmitted to the parking guidance control unit 7.

  The steering angle sensor 10 is attached to the steering wheel, detects an operation amount and an operation direction of the steering wheel, and transmits the detected amount to the parking guidance control unit 7.

  The parking guidance control unit 7 calculates a control command signal for guiding and controlling the host vehicle to the parking target position designated by the parking target position designating unit 6 while feeding back the value detected by the steering angle sensor 10. The obtained control command signal is input to the EPS motor 11.

  The EPS motor 11 operates the power steering based on a control command signal from the parking guidance control unit 7 so that the host vehicle can park at the target parking position.

[Operation of parking assist device]
Next, parking assistance processing by the parking assistance apparatus 1 according to the present embodiment will be described with reference to the flowchart of FIG. The algorithm of the parking assistance process shown in FIG. 3 is implemented by timer interruption, and the parking assistance process is implemented by performing it every preset sampling time.

  As shown in FIG. 3, in step S <b> 101, images around the host vehicle are captured by the cameras 8 a to 8 d, and the captured images are transmitted to the overhead image generation unit 2.

  Next, in step S102, the bird's-eye view image generation unit 2 performs viewpoint conversion on the images around the host vehicle captured by the cameras 8a to 8d, and generates the bird's-eye view images around the host vehicle. Here, an example of the overhead view video generated by the overhead view video generation unit 2 is shown in FIG. As shown in FIG. 4, a bird's-eye view image 42 is formed by arranging computer graphics 40 indicating the position of the host vehicle in the center and displaying images 41a to 41d whose viewpoints are converted in the surrounding four directions side by side. The video 41a is obtained by converting the viewpoint of the image in front of the host vehicle captured by the camera 8a, and the images 41b and 41c are the viewpoints converted from the left and right images of the host vehicle captured by the cameras 8b and 8c. Is a viewpoint-converted image of the rear of the host vehicle captured by the camera 8d. Note that it is not necessary that all the images in the four directions are completely displayed in the overhead image 42. For example, only the images 41b and 41c corresponding to the horizontal direction are displayed in the overhead image 42, and the images in the front-rear direction are the cameras 8a and 8d. It is also possible to display the image itself captured in step (b).

  When the bird's-eye view video is generated in this way, in step S103, it is determined whether or not a parking assistance start signal from the driver is input to the input unit 3. If a parking support start signal is detected by the driver pressing the start button or the like, the process proceeds to step S104, and if not detected, it is determined that parking support is not performed and the process ends.

  In step S104, the temporary parking target position setting unit 4 sets an image of the temporary parking target position. For example, it is sufficient to read and prepare an image of the temporary parking target position stored in advance in the memory, or change the size of the read temporary parking target position image or change the color and brightness. You may do it.

  Here, the image of the temporary parking target position which concerns on this embodiment is shown in FIG. As shown in FIG. 5, in this embodiment, computer graphics 50 indicating the position of the host vehicle is arranged at the center, and the temporary parking target position is expressed by drawing saddle-shaped marks on the left and right. Among the images of the temporary parking target position shown in FIG. 5, the two saddle shapes of the mark 52 a and the mark 52 b indicate images of the temporary parking target position corresponding to the left side parallel parking. The two diagonally oriented line segments of the mark 53a and the mark 53b show images of the temporary parking target position corresponding to the diagonal parking of 45 degrees on the left side. The two saddle shapes of the mark 54a and the mark 54b indicate temporary parking target positions corresponding to the left side parallel parking. Similarly, the mark 55a and the mark 55b indicate the temporary parking target position corresponding to the right side parallel parking frame, the mark 56a and the mark 56b indicate the temporary parking target position corresponding to the right side oblique parking, and the mark 57a and the mark 57b are The temporary parking target position corresponding to the right side parallel parking is shown.

  In the present embodiment, the images 52a and 52b of the temporary parking target position corresponding to the left side parallel parking are drawn at symmetrical positions across the position of the door mirror where the camera 8c is installed. By drawing in this way, drawing is performed close to the position of the camera 8c and at an equal distance from the camera 8c, so that the distortion of the video generated when the video of the camera 8c is converted into a bird's-eye video is minimized. be able to. The same applies to the images 53a and 53b and the right side of the temporary parking target position corresponding to the diagonal parking.

  However, the images 54a and 54b of the temporary parking target position corresponding to the left side parallel parking are drawn behind the host vehicle. This is because the parking target position and the return position are displayed after parking support is started, but in the case of parallel parking, if the parking target position is not set to the rear of the vehicle due to the characteristics of the trajectory, the return position in the initial state. This is because it cannot be displayed in the overhead view video. Therefore, in the present embodiment, the images 54a and 54b of the temporary parking target position corresponding to the parallel parking are set to be behind the vehicle so that the switching position can be displayed in the overhead view video. By displaying the turn-back position in the bird's-eye view in this way, the driver can understand at a glance how far he / she should advance his / her vehicle after the start of parking assistance. A sense of security can be improved. The same applies to right side parallel parking.

  Next, in step S105, the overhead image generated in step S102 and the image of the temporary parking target position set in step S104 are superimposed by the image superimposing unit 5 to generate a superimposed image. The obtained superimposed image is sent to the display unit 9 and displayed on a monitor of a car navigation system. An example of the superimposed image is shown in FIG. As shown in FIG. 6, computer graphics 60 indicating the position of the host vehicle is arranged at the center, and saddle-shaped temporary parking target positions are displayed on the left and right sides thereof.

  When the superimposed image is displayed on the display unit 10 in this way, in step S106, the driver looks at the display of the superimposed image so that the actual parking target position and the temporary parking target position substantially coincide with each other. The parking assistance start position is determined by guiding. For example, as shown in FIG. 6, in the case of parallel parking on the left side, the parking assistance start position is determined by guiding the host vehicle so that the temporary parking target positions 62 a and 62 b substantially coincide with the actual parking target position 61. At this time, the host vehicle is guided by steering, braking and driving operations of the host vehicle by the driver. Note that the host vehicle can be guided to the parking assist start position by performing the same operation even in the case of parallel parking or diagonal parking.

  In this way, the driver designates the parking start position by matching the temporary parking target position superimposed on the bird's-eye view image in advance with the actual parking target position, and the parking route starting from the start position is stored in the memory. Since parking guidance control is performed after reading, image recognition is not necessary, and the load on the CPU can be reduced.

  Next, in step S107, after prompting the driver to select a parking mode such as parallel parking, parallel parking, and diagonal parking, through the parking target position designating unit 6, the temporary parking target position displayed in the superimposed image is displayed. It is determined whether a temporary parking target position corresponding to the actual parking target position is designated. Here, when the determination button is pressed and the parking target position is designated, the process proceeds to step S108, and when the cancel button or the like is pressed and an intention to cancel the parking support is displayed, the parking support process is ended. .

  Further, the image of the temporary parking target position described above can be displayed lightly before the parking target position is designated, and can be highlighted after the parking target position is designated. For example, as shown in the parking target position 70 of FIG. 7, after the parking target position is designated, the parking target position may be surrounded by a solid line and highlighted in a darker color. The same applies to the case of parallel parking shown in FIG. By displaying in this way, the visibility of the overhead view image can be improved before the parking guidance control, and the driver can clearly recognize the parking target position during the parking guidance control.

  When the parking target position is designated and the process proceeds to step S108, a parking support image corresponding to the designated parking target position is displayed superimposed on the overhead view video of the display unit 9. For example, a parking target position 70 and a turn-back position 71 as shown in FIG. 7 are displayed in the case of left side parallel parking, and a parking target position 80 and a turn-back position as shown in FIG. 8 in the case of left side parallel parking. 81 are displayed.

  Next, in step S109, guidance control by the parking guidance control unit 7 is performed. In this guidance control, parking assistance is performed according to the control logic, and a route for guiding the vehicle is first generated. This guidance route can be realized by holding a route corresponding to each of parallel parking, parallel parking, and diagonal parking in the memory one by one and reading a route corresponding to the designated parking target position. The guidance route calculated by the parking guidance control is a curve from the position to the parking target position by switching to the curve to the turn-back position.

  The parking guidance control unit 7 calculates a command signal to the EPS motor 11 installed in the power steering while feeding back the value of the steering angle sensor 10 so as to follow the calculated guidance route. The calculated command signal is sequentially transmitted to the EPS motor 11, and parking guidance control is performed. At this time, it is assumed that the driver performs the braking and driving command of the vehicle and the forward / reverse switching operation.

  However, in addition to the above-described parking guidance control, for example, a route line expected to pass by the host vehicle is calculated from the steering angle and the vehicle speed and superimposed on the display unit 9 to assist and guide the driver's steering. Just be fine. Moreover, the guidance method which notifies only the timing of steering turning, a brake, and an accelerator may be used.

  When the parking guidance control in step S109 is performed in this manner and the parking at the parking target position is completed, the parking support process shown in FIG. 3 ends.
