Description

[0001] Control Apparatus Of Vehicle [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a vehicle control apparatus, and more particularly, to a vehicle control apparatus that performs vehicle control using a tire steering angle.

Generally, the part related to the steering angle in the vehicle control is not used to directly measure the steering angle of the tire but is used for the vehicle control by measuring the rotation angle using the steering wheel and the rotation sensor built in the column side.

1 is a perspective view showing a state in which a vehicle control device is installed.

Referring to FIG. 1, a McPherson type suspension device includes a steering wheel 1, which can perform a steering operation, and a rack gear 2, which is disposed in a steering column 2 in accordance with a steering operation of the steering wheel 1, Is transmitted to the wheel 7 by the steering link mechanism 4 to change the direction of the wheel 7.

As described above, a rotation sensor is installed on the steering wheel column 2 so as to steer the wheel 7 in proportion to the steering angle of the steering wheel 1, and the rotation angle of the steering wheel 1 is measured. That is, the rotation sensor measures the rotation angle of the steering wheel 1 so that the steering angle of the wheel uses the input rotation angle of the steering wheel so that the wheel 7 is steered in proportion to the steering angle.

However, if the steer angle of the steering wheel 1 is used to replace the steering angle at which the wheel 7 rotates, the tolerance and the bushing when assembling the related components may be distorted, There is a problem that an error occurs. The error of the steering angle does not sufficiently reflect the steering angle of the actual wheel 7 when the vehicle is controlled, which is disadvantageous for vehicle control.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle control device that elaborates a vehicle control using a steering angle at which a tire rotates when controlling a vehicle attitude.

The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

In order to accomplish the above object, a vehicle control apparatus according to an embodiment of the present invention includes a steering knuckle having a lower end hinged to a lower arm by supporting a wheel rotatably, a steering knuckle whose one end is coupled to the steering knuckle, And a strut for fixing the other end to the vehicle body and measuring a rotation angle of the wheel when the wheel is rotated.

The strut bearing may include a rotation sensor installed on the strut bearing and configured to measure a rotation angle of the vehicle when the wheel rotates.

Further, the rotation sensor is installed outside the strut bearing.

The strut bearing may include an upper race, a lower race coupled to the upper race, a ball for reducing friction between the upper race and the lower race, and the rotation sensor may be installed on the upper race .

In addition, the rotation sensor may include a magnetic encoder provided to face the rotation sensor to measure a rotation angle of the rotation sensor when the lower race is rotated.

In addition, the magnetic encoder may rotate together with the lower race to measure a rotation angle of the rotation sensor.

The details of other embodiments are included in the detailed description and drawings.

According to the vehicle control apparatus of the present invention, one or more of the following effects can be obtained.

First, there is an effect that a steering signal inputted from a steering wheel can be verified and corrected for a signal transmitted by an electronic method and an error about an actual steering angle.

Second, since the steering angle used in the vehicle steering control uses the steering angle corresponding to the rotation of the tire, the error due to assembly and deformation of the parts is reduced and the control can be finely controlled.

Third, the rotation sensor is mounted on the strut bearing, thereby reducing the cost.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

A preferred vehicle control apparatus may be modified by a person having ordinary skill in the art, and is a vehicle control apparatus in an embodiment of the present invention.

Fig. 2 is an enlarged view of the strut of Fig. 1, and Fig. 2 is a perspective view.

2, the vehicle control apparatus according to the present invention includes a lower arm that supports a wheel so as to be rotatable, a steering knuckle that is hinged to the lower arm, a steering knuckle that is coupled to the steering knuckle, As shown in FIG.

The steering knuckle 10 supports the wheel rotatably so that its lower end is hinged to the lower arm. A wheel is rotatably supported on a steering knuckle 10 and a lower end of a strut 20 fixed to a vehicle body is fastened to an upper side of the steering knuckle 10.

Fig. 3 is a perspective view showing a strut bearing installed in the strut of Fig. 2; Fig.

Referring to FIG. 3, the strut bearing 30 is installed at the upper end of the strut 10. A rotation sensor (40) is installed on the strut bearing (30) to measure the turning angle of the vehicle when the wheel (7) is rotated. The strut bearing 30 is provided with an upper race 34 and a lower race 38 coupled to the upper race 34. A ball is provided between the upper race 34 and the lower race 38 to reduce friction caused by the rotation of the lower race 38. [

The upper race 34 is fixedly engaged with the vehicle body. The upper lace 34 is provided with a rotation sensor 40. The lower race 38 is rotatably coupled to the strut 20. The lower race 38 is adapted to engage under the upper race 34. The lower lace 38 is equipped with a magnetic encoder 50.

Fig. 4 is a cross-sectional view showing A-A in Fig. 3, and Fig. 5 is a cross-sectional view showing a part of Fig. 4 on an enlarged scale.

4 and 5, the rotation sensor 40 is installed on the outer periphery of the strut bearing 30. [ The rotation sensor 40 is installed on the outer circumference of the upper race 34, and the sensing portion is installed so as to face the outer circumference of the lower race 38. The sensing unit of the rotation sensor 40 is installed to face the magnetic encoder 50 installed on the lower race 38 and senses the rotation angle of the magnetic encoder 50 when the lower race 38 rotates.

The magnetic encoder (50) is installed in the strut bearing (30). The magnetic encoder 50 is installed on the outer periphery of the lower race 38 so as to face the rotation sensor 40 on the lower race 38. Therefore, when the wheel is rotated, the magnetic encoder 50 is also rotated by the lower race 38 together.

The operation of the vehicle control apparatus according to the present invention will now be described.

2 to 5, the upper end of the strut 20 is mounted on a vehicle body (not shown), and the lower end is supported by a knuckle arm. At this time, the strut 20 is installed at the upper end of the strut 20 so that the strut bearing 30 is disposed between the upper end of the strut 20 and the vehicle body when the upper end of the strut 20 is mounted on the vehicle body.

The upper race 34 of the strut bearing 30 is engaged with the vehicle body and the lower race 38 is engaged with the strut 20 so that the lower race 38 is rotated upon rotation of the wheel.

That is, when the McPherson strut suspension of the present invention configured as described above is steered, the wheel 7 rotates about the center shaft of the lower strut bearing 30 and the lower strut bearing 30. Therefore, when the wheel 7 is rotated about the center pin X of the king pin, the magnetic encoder 50 rotates while the lower race 38 rotates.

The upper race 34 fixed to the vehicle body rotates the lower race 38 by the rotation of the wheel 7 so that the rotation sensor 40 detects the rotation of the wheel 7 relative to the body measured from the magnetic encoder 50 The measured angle of rotation is the actual steering angle of the wheel 7.

Therefore, by using the vehicle control device as in the present invention, accurate control of the vehicle is possible when the rotation angle is used during vehicle control.
