As shown in FIG. 1, the steering value calculation processing apparatus of the present invention includes a magnetic guider 1, a wheel steering sensor 3, and a microcomputer 5, and the magnetic guider 1 is physically a rotating body. Generates a magnetic field from the following ("steering wheel"), the wheel steering sensor unit 3 detects the magnetic field and transmits an electrical signal (hereinafter, referred to as a steering value) of the steering wheel Wheel steering signal), and the microcomputer 5 receives the wheel steering signal and an electrical signal corresponding to the steering value (driving direction) of the wheel by a predetermined algorithm (hereinafter referred to as a wheel steering signal). Outputs

First of all, the rotation of the steering wheel 10 (or steering wheel) of the vehicle is directly transmitted to the vehicle wheels so that the steering wheel 10 transmits power through the steering column 12 in order to convert the steering angle, thereby enabling the driver to drive desired. . In particular, the wheel steering sensor unit 3 and the magnetic guider 1 are rotatably coupled to the column cover 13 surrounding the steering column 12 and the space between the column cover 13. The wheel bodies 15 are integrally connected to the lower part of the steering wheel 10.

It is attached to the bottom surface of the wheel body 15 of the steering wheel 10, also known as a rotating body, and generates a magnetic field to determine the steering value at which the steering wheel 10 is rotated by the wheel steering sensor unit 3 below. At least one magnetic point 7 is placed and buried at an equiangular point by the circumferential angle of any one of 360 °, 180 °, 90 °, 60 °, 45 ° and 30 ° along the circumferential track for sensing. The strength of the magnetic field is enough to be sufficiently sensed at a predetermined distance from the wheel steering sensor 3. Here, the separation distance is preferably within a maximum of 1cm.

The magnetic point 7 is embedded in the magnetic guider 1 and may shield the magnetic field 7 so that the magnetic field is formed in one direction so as to maintain a state in which the generated magnetic field is sensitively sensed.

The wheel steering sensor unit 3 is disposed on the other side of the opposing surface to which the magnetic guider 1 is bonded in order to detect one or more magnetic points 7 formed on the magnetic guider 1. It is coupled to a hidden surface, which is a rear surface of the upper surface of the column cover 13, also called a fixed body, and corresponds to the circumferential direction corresponding to a single section of the point equiangular interval so as to face the magnetic guider 1. At least three or more Hall sensors 9 are arranged by the circumferential angle at an equiangular interval of any one of 1 °, 3 °, 5 °, 10 °, 15 °, and 20 ° along a track of the magnetic field. The control unit generates a wheel steering signal corresponding to the wheel steering value (rotation direction and rotation angle) of the steering wheel 10.

The magnetic point 7 of the magnetic guider 1 and the hall sensor 9 of the wheel steering sensor unit 3 as described above are configured in the arrangement as shown in FIGS. 4A to 4C.

That is, when one magnetic point 7 is disposed on a circumferential track of 360 °, the single section of the point isometric interval is 360 °, so the hall sensor 9 corresponds to a single section of the point isometric interval of 360 °. The circumferential tracks are arranged at an equiangular interval of 15 °, which is one of 1 °, 3 °, 5 °, 10 °, 15 °, and 20 °.

The wheel steering signal as described above is processed by the wheel steering signal corresponding to the wheel steering value by the microcomputer (). That is, the microcomputer 5 receives the wheel steering signal calculated by the wheel steering sensor unit 3 and sets the set angle corresponding to a unique position of each of the plurality of hall sensors 9 and the number of the magnetic points 7. The steering angle of the steering wheel 10 is calculated, and the wheel steering value of the vehicle corresponding to the rotation angle is calculated in real time to generate a corresponding wheel steering signal. Here, the wheel steering signal of the wheel steering sensor unit 3 and the wheel steering signal of the microcomputer 5 are transmitted to the vision processing system, the traveling cruise system and auxiliary electronic devices for controlling the vehicle, and the automation and safety of the vehicle. Their systems for applications can improve the comfort and safety of motorists.

The algorithm for calculating and processing the wheel steering value and the wheel steering value in the microcomputer 5 recognizes the set wheel steering value corresponding to the position where the hall sensor 9 is disposed at an equiangular interval along the circumferential direction, Among the hall sensors 9 arranged at an interval, the inherent wheel steering value (rotation angle of the steering wheel) X corresponding to the circumferential position of the hall sensor 9 detected and the entire hall sensors 9 arranged are The actual wheel steering value H in which the actual wheel is moved in the circumferential direction is calculated by calculating the cycle number Y sequentially detected and the circumferential angle Z on which the hall sensor 9 is arranged using an algorithm X + (Z × Y). The wheel steering value V corresponding to the actual wheel steering value is calculated again.

Here, the range of the actual wheel steering value calculated above is 560 ° in the left direction (-) to 560 ° in the right direction (+), and the range of the wheel steering value is 38 ° to the right direction in the left direction (-). Since it is 38 ° of (+), the wheel steering value can be obtained by applying a method in which the actual wheel steering value and the wheel steering value are mutually proportional to each other.

Operation of the present invention as described above is as shown in Figures 5a and 5b.

First, two magnetic points 7 of the magnetic guider 1 attached to the steering wheel 10 are arranged in a 360 ° circumferential track at 180 ° point isometric intervals, and a single section of the point isometric intervals is Since the hall sensor 9 of the wheel steering sensor unit 3 mounted on the column cover 13 is 180 °, 13 circumferential tracks corresponding to a single section of 180 ° point isometric intervals are separated by 13 ° isometric intervals. It is arranged.

As shown in FIG. 5A, two magnetic points 7 are disposed at 0 ° and 180 °, respectively, at 0 ° where the steering wheel 10 is a reference point, and the Hall sensor 9 of the wheel steering sensor unit 3 is Thirteen are arranged at an equiangular interval of 15 degrees. However, as shown in FIG. 5B, when the steering wheel 10 is rotated, the magnetic point 7 moves along the circumferential track on which the hall sensor 9 is disposed, and the hall sensor for detecting the magnetic field of the magnetic point 7 ( 9) generates the steering value (angle value) as an electric wheel steering signal.

Then, the microcomputer 5 is arranged with a unique wheel steering value (rotation angle of the steering wheel) X corresponding to the circumferential position of the hall sensor 9 detected among the hall sensors 9 arranged at an equiangular interval. If the cycle number Y in which all the hall sensors 9 are sequentially detected and the circumferential angle Z in which the hall sensors 9 are arranged are calculated by an algorithm X + (Z × Y), the cycle number is 0, and thus the intrinsic The wheel steering value of calculates a corresponding wheel steering signal due to the rotation angle of the steering wheel 10, and generates an electric wheel steering signal which is a steering value of the corresponding wheel.
