Abstract
This invention provides a simple but exact two step parallel parking assistive procedure based on the mathematical solutions. This parallel parking procedure use no sensor nor computer to produce commands in executing the said parallel parking procedure but with two sets of pointers' assistance with crosshair lines of the pointers for the visual guidance to the drivers by simple attachment of the said set of pointers to the existing vehicles. This parking procedure comprises two steps; one rotational movement along the one circle turn center predetermined by the said mathematical calculation followed by a final rotational movement along the other circle turn center also predetermined by the said mathematical calculation. If the vehicle is to be parked on the left side of the road, the sets of pointer should be pointing to the left side of the vehicle accordingly. To make the system simple, those two sets of the pointers could be replaced by one set of pointers working both for the location of the starting position of the vehicle as well as for the orientation of the vehicle to identify the transition instant.

The present invention provides a simple but exact parallel parking procedure based on a mathematical solution. This said parallel parking procedure comprises two steps; one rotational movement along the one circle turn center followed by a second rotational movement along the other circle turn center without using any sensors nor computer for producing commands to execute the said parallel parking procedure manually.
FIG. 1 is a top view showing the positions of the two sets of pointers attached to a vehicle to be parallel parked and the parking process using thereof according to an exemplary embodiment of the present invention.
Referring to FIG. 1, a XY coordinate system 11 is defined as the one having its origin at the barrier corner 10 which is the beginning point of the first barrier ban, with the x-axis ha along the first barrier ban. The position of the starting vehicle 16a which is the vehicle in the starting position in the said parallel parking procedure is obtained by a set of location pointers 12 which make the starting vehicle 16a to have proper side space spc 1 from the first barrier bar 1 as well as an appropriate distance longitudinally from the ban-ier corner 10 along the first barrier barn to make the right circle turn center 1 coinciding with the right circle turn center la which is predetermined by a mathematical calculation.

Then the vehicle keeps moving backward around the left circle turn center 2b until to reach the rear barrier bar3, becoming the terminus vehicle 16c.
Hereinafter, a method of proper installment of these said sets of pointers will be described in the following explanation of FIG. 4.
FIG. 2 shows a parallel parking procedure of the vehicle according to the 7-step algorithm suggested by MacDonnell at the web site https://www.goauto.ca/blog/
how-to-parallel-park-parallel-parking-steps:
Date Recue/Date Received 2022-10-05 1) Look for a space large enough to parallel park into. A good rule of thumb is that there should be at least a vehicle-and-a-half worth of space separating the two vehicles you're planning to parallel parking between. Once you've found a big enough space.
2) Pull up alongside the vehicle in front of your parking space. Align your back wheels with the back bumper of that vehicle. Stop.
3) Turn your steering wheel as far as you can to the right before you start to pull into the space.
4) Slowly back into the parking space, keeping your steering wheel as far to the right as possible while you do this. Your back right wheel should eventually line up with the back left corner of the vehicle just as your front right wheel lines up with the same comer. See the video above if you'd like a visual aid.
5) Once your front right wheel has lined up with the back left comer of the vehicle in front of you, turn your wheel as far to the LEFT as you can, and then slowly back up in to the space.
6) Once you're in the space, pull ahead slightly to give the vehicle behind you enough room to pull out.
7) Finished.
As this 7-step algorithm does not consider the variation of geometrical characteristics of individual vehicles, the terminus vehicle 16c at the end of the parallel parking procedure is too off from the shoulder in this example.
FIG. 3 is a top view of the vehicle showing the geometrical specification of the vehicle with the right circle turn center 1 which is located on the rear axle ax12 using the turn radius 7 from the automaker's published data and equal to the distance from the left end point of the front axle axll to the right circle turn center 1 according to Ackerman steering geometry (Wikipedia). The left circle turn center 2 is located by the mirror image of the right side. The arm length 4 is defined as the distance from the right circle turn center 1 to the right rear axle point 3 of the rear axle ax12. The body arm length 5 is defined as the distance from the right rear axle point 3 to the left circle turn center 2. The total length 6 is defined as the distance from the left circle turn center 2 to the right circle turn center 1. The sweep distance 8 is defined as the distance from the right front end 9 of the front end endl to the left circle turn center 2.
FIG. 4 is a view showing the procedure of finding the exact locations of the turn circles locating the left circle turn center 2b of the transition vehicle 16b at the instant when the center of rotation is to be shifted from the right one to the left one by fully turning the steering in the said parallel parking procedure.
The said procedure of the finding the left circle turn center 2b is as follows: first step is locating the barrier corner neighbor 10a which is away from the barrier corner 10 with appropriate comer space 5pc2, and the right rear axle point 3c of the terminus vehicle 16c decided from considering the back space spc3 from the rear barrier bar3 plus the overhang Date Recue/Date Received 2022-10-05 distance determined from the rear axle ax12 to the rear end end2 of the vehicle providing the rear end of the vehicle does not protrude the shoulder denoted by the shoulder barrier bar2.
Then the left circle turn center 2b is located by the intersection of two circles: One circle has the center at the barrier corner neighbor 10a with the radius equal to the sweep distance 8, and the other circle has the center at the right rear axle point 3c with a radius equal to the body arm length 5.
Then the right circle turn center la is located by the intersection of a straight line with a circle: the straight line parallel to the x-axis 11 a and having distance equal to the arm length 4 from the right side of the starting vehicle 16a which has the side space spcl from the first barrier ban, and the circle having the center at the left circle turn center 2b with the radius equal to the total length 6. Once the right circle turn center la is identified, the starting position of the starting vehicle 16a enables to secure the orientation of the set of location pointers 12 to aim at the barrier corner 10. The line between the left circle turn center 2b and the right circle turn center la identifies the rear axle ax12b at the transition vehicle 16b.
This rear axle ax12b makes an angle with the x-axis 1 la and denoted as the transition angle 14.
This transition angle 14 is used to fix the transition angle 15 of the set of orientation pointers 13.
Now, the said parallel parking procedure is ready to execute in two steps as explained in the following:
1) The first step of the parallel parking procedure is initiated by letting the starting vehicle 16a to be located at the proper position using the guidance of the first set of location pointers 12: Move the starting vehicle 16a to let the set of location pointers 12 to point at the barrier corner 10 while keeping the starting vehicle 16a parallel to the x-axis ha. Then, move the said starting vehicle 16a backward in rotation around the right circle turn center lb keeping the steering wheel fully rotated to the right until the set of orientation pointers 13b of the transition vehicle 16b are pointing vertical to the x-axis lla or parallel to the shoulder by the crosshair line of the set of orientation pointers 13b.
2) At that instant when the set of orientation pointers 13b pointing vertical to the x-axis 11a, turn the steering wheel fully to the left and move backward in rotation around the left circle turn center 2b until the vehicle reach the rear barrier bar3 or the terminus vehicle 16c is ready to fine adjust the terminus vehicle 16c on the proper parking position to finish the parallel parking procedure.
The invention has been described in detail with reference to preferred embodiments thereof. However, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
