  Next, a description will be given of an example in which the vehicle A is parked in parallel in the parking space X behind the adjacent vehicle B. First, the vehicle A stops near the adjacent vehicle B so as to be parallel to the adjacent vehicle B. When it is desired to park the vehicle A in the parking space X, first, the vehicle tail portion A1 of the vehicle A is directed to the parking space X, and the auxiliary guidance device for vehicle reverse parking according to the present invention is activated. By determining that the vehicle has started, a simulated vehicle reverse signal and a video synchronization signal are generated and output to the car audio D, whereby the screen of the screen D1 of the car audio D is switched to the vehicle reverse video input terminal. When the user selects the video by the vehicle side surface photographing unit 32 by the video switching unit 33 and displays it on the screen D1, the screen menu unit 20 is also displayed on the screen D1. When the user first selects the parking mode by the route selection button unit 12, the screen menu unit 20 can display the presentation notation M corresponding to the selected parking mode on the screen D1 of the car audio D. Then, the user can display the video captured by the vehicle side surface imaging unit 32 facing the adjacent vehicle B on the screen D1 of the car audio D by switching the video switching unit 33. Thereafter, as shown in FIG. 3, the scheduled parking position M1 of the presentation notation M is substantially parallel to the side of the adjacent vehicle B, and the obstacle boundary line M2 is parallel to the horizontal line at the bottom of the wheel of the adjacent vehicle B. . When the user moves and selects the optimum planned parking position M1 by the route selection button unit 12, the presentation notation M displays the obstacle boundary line M2 corresponding thereto. Thus, when the user moves and selects the optimum planned parking position M1, the user is made aware that the obstacle boundary line M2 should not overlap with the rear wheel of the adjacent vehicle B. After the user selects the planned parking position M1, the optimum reverse rotation path calculation software 11 in the CPU 10 can calculate the virtual optimal reverse rotation path S according to the selected parking mode. As shown in FIG. 2, the virtual optimum reverse rotation path S includes a first-stage path S1 and a second-stage path S2 that are connected to each other.

  At this time, first, the vehicle A is reversed in a straight line, and the obstacle boundary line M2 of the presentation notation M on the screen D1 moves together with the vehicle A when the vehicle A is continuously reversed. When the obstacle boundary line M2 on the screen overlaps the vehicle tail B1 of the adjacent vehicle B, the vehicle A is located at the starting point of the virtual optimum reverse rotation path S. At this point, the CPU 10 notifies the user that the next operation will be started soon by an alarm or voice by the voice presentation unit 50. At this time, characters and patterns may be displayed on the screen D1 to make the user aware.

  The auxiliary guidance device for reverse vehicle parking according to the present embodiment causes the user to move toward the parking space X when the user notices that the next operation will be started soon by an alarm or sound. Rotate the handle to the limit. At this time, the displacement measuring unit 40 simultaneously measures the displacement distance and the rotation angle of the vehicle A. When the displacement path of the vehicle A matches the numerical value of the first stage path S1 of the virtual optimal reverse rotation path S by the measurement of the displacement measurement unit 40, the CPU 10 controls the voice presentation unit 50 to generate an alarm, and soon Make the user aware that it is going into action. During the guidance process, when the operation is not performed according to the rotation angle designated by the user, the reverse parking guidance is canceled and the user can steer the vehicle A by himself.

  Next, when the voice presentation unit 50 generates an alarm, the vehicle A completes the movement of the first step path S1 according to the guidance. At this time, the operation to be performed by the user reverses the steering wheel to the limit, and the displacement measuring unit 40 simultaneously measures the displacement distance and the rotation angle of the vehicle A. When the displacement path of the vehicle A matches the numerical value of the second stage path S2 of the virtual optimum reverse rotation path S by the measurement of the displacement measurement unit 40, the CPU 10 controls the voice presentation unit 50 to generate an alarm, and Make the user aware that parking is complete.

  In this embodiment, the method for determining the distance between the vehicle A and the adjacent vehicle B uses the planned parking position M1 displayed on the screen menu unit 20 as a reference for comparison. There is also a method in which the distance measurement unit 60 is assembled on the side of the vehicle A, and the distance between the vehicle A and the adjacent vehicle B is directly measured by the distance measurement unit 60 electrically connected to the CPU 10. According to the above method, the optimal reverse path calculation software 11 can calculate the virtual optimal reverse path based on the measured vehicle distance, and can also calculate the fault boundary line M2 corresponding to the virtual optimal reverse path. After displaying the failure boundary line M2, the same operation as described above can be performed, and the same object and effect can be achieved.

  In the above description, the case where the vehicle A is parked in parallel with the parking space X has been described as an example. However, the present invention is such that the vehicle A is perpendicular to the parking space X as shown in FIGS. You can also park.

  First, the vehicle A is stopped so as to be perpendicular to the parking space X, and the parking space X is located on the right side of the vehicle A. When it is desired to park the vehicle A in the parking space X, first, the auxiliary guidance device for reverse vehicle parking of the present invention is activated, and the CPU 10 determines that the reverse parking of the vehicle has started, and the simulated vehicle reverse signal and video By generating a synchronization signal and outputting it to the car audio D, the screen D1 screen of the car audio D is switched to the vehicle reverse video input end. At this time, the user uses the video switching unit 33 to capture the rear of the vehicle. The video by the unit 31 is selected and displayed on the screen D1, and the screen menu unit 20 is also displayed on the screen D1. At the same time, the screen menu unit 20 can display the presentation notation M corresponding to the selected parking mode on the screen D1 of the car audio D. And the user can display the video image | photographed by the vehicle side surface imaging unit 32 or the vehicle rear surface imaging unit 31 on the screen D1 of the car audio D by switching the image switching unit 33. Thereafter, as shown in FIG. 7, the planned parking position M1 of the presentation notation M is substantially parallel to the side of the adjacent vehicle B, and the obstacle boundary line M2 is parallel to the horizontal line at the bottom of the wheel of the adjacent vehicle B. . When the user moves and selects the optimum planned parking position M1 by the route selection button unit 12, the presentation notation M displays the obstacle boundary line M2 corresponding thereto. Thus, when the user moves and selects the optimum planned parking position M1, the user is made aware that the obstacle boundary line M2 should not overlap with the rear wheel of the adjacent vehicle B. After the user selects the planned parking position M1, the optimum reverse rotation path calculation software 11 in the CPU 10 can calculate the virtual optimal reverse rotation path S according to the selected parking mode. As shown in FIG. 6, the virtual optimum reverse rotation path S includes a first stage path S1 and a second stage path S2 that are connected to each other.

  At this time, first, the vehicle A is moved in a direction perpendicular to the parking space X, and the obstacle boundary line M2 of the presentation notation M on the screen D1 moves together with the vehicle A when the vehicle A is moved continuously. When the obstacle boundary line M2 on the screen overlaps the vehicle side part B2 of the adjacent vehicle B, the vehicle A is located at the starting point of the virtual optimum reverse rotation path S. At this point, the CPU 10 notifies the user that the next operation will be started soon by an alarm or voice by the voice presentation unit 50. At this time, characters and patterns may be displayed on the screen D1 to make the user aware.

  The auxiliary guidance device for reverse vehicle parking according to the present embodiment causes the user to move away from the parking space X when the user notices that the next operation will be started soon by an alarm or sound. Rotate the steering wheel to the limit and move the vehicle forward. At this time, the displacement measuring unit 40 simultaneously measures the displacement distance and the rotation angle of the vehicle A. When the displacement path of the vehicle A matches the numerical value of the first stage path S1 of the virtual optimal reverse rotation path S by the measurement of the displacement measurement unit 40, the CPU 10 controls the voice presentation unit 50 to generate an alarm, and soon Make the user aware that it is going into action. During the guidance process, when the operation is not performed according to the rotation angle designated by the user, the reverse parking guidance is canceled and the user can steer the vehicle A by himself.

  Next, when the voice presentation unit 50 generates an alarm, the vehicle A completes the movement of the first step path S1 according to the guidance. At this time, the operation to be performed by the user reverses the vehicle A by reversing the steering wheel to the limit. Then, the displacement measurement unit 40 measures the displacement distance and the rotation angle of the vehicle A at the same time. When the displacement path of the vehicle A matches the numerical value of the second stage path S2 of the virtual optimum reverse rotation path S by the measurement of the displacement measurement unit 40, the CPU 10 controls the voice presentation unit 50 to generate an alarm, and the vehicle A The user is made aware that he has arrived at a position that matches the angle of the parking space X. Thereafter, the vehicle A can be parked in the parking space X when the vehicle A is reversed straight.

  In this embodiment, the method for determining the distance between the vehicle A and the adjacent vehicle B uses the planned parking position M1 displayed on the screen menu unit 20 as a reference for comparison. There is also a method in which the distance measurement unit 60 is assembled on the side of the vehicle A, and the distance between the vehicle A and the adjacent vehicle B is directly measured by the distance measurement unit 60 electrically connected to the CPU 10. According to the above method, the optimal reverse path calculation software 11 can calculate the virtual optimal reverse path based on the measured vehicle distance, and can also calculate the fault boundary line M2 corresponding to the virtual optimal reverse path. After displaying the failure boundary line M2, the same operation as described above can be performed, and the same object and effect can be achieved.

  As is apparent from the above description, the present invention can provide simple comparison and presentation as a basis for guidance by measuring the vehicle's marching state and planning the built-in virtual optimal reversal path in advance. . The user can easily complete reverse parking by following the guidance and rotating the handle to the limit in one direction, reversing it to the limit in the other direction, and moving forward or reverse in view of the field conditions. Since the vehicle guidance is not automatically completed, the user can pay attention to the driving situation of the vehicle during the process of guiding the vehicle, and can secure the driving safety. Since the purpose of the present invention is to provide guidance and the vehicle A is steered by the user, the present invention does not maneuver the vehicle, no precise control system or mechanism is required, and the production cost of the entire apparatus can be greatly reduced. The function of guidance can be demonstrated reliably. In this way, consumers' desire to purchase can be greatly increased.

  The present invention can be applied to an auxiliary parking guidance device.
