Problems solved by technology

Since the length of the semi-trailer compartment of the semi-trailer is generally more than ten meters or more, the value of the inner wheel difference is generally relatively large, up to more than 2 meters. Moreover, it involves the cooperation of the tractor and the semi-trailer, so in the driving state, the blind spot of the driver's vision is large, and it is difficult to fully control the state of the vehicle. In addition, the problem of inner wheel difference will form a potential safety hazard caused by the problem of vision.

Embodiment 1

[0032] Such as figure 2 , Figure 5 with Image 6As shown, the angle formed by the axis of the tractor and the center line of the semi-trailer is θ, and the angle formed between the line connecting the probe 9 and the center of the saddle 7 and the center line of the tractor 6 is λ; when the vehicle When driving forward, the reversing sensor 2 does not touch the shift lever 13, so the signal transmitted to the control device 11 is a non-reversing signal; the control device 11 will give a command to the motor 2, so that the motor 2 drives the vehicle located on the side of the rear of the semi-trailer 1. The left and right cameras 5 are facing the front of the vehicle, and the shooting pictures of the left and right cameras 5 are displayed on the display 14. At this time, the display 14 displays the pictures of the left and right cameras 5 simultaneously.

[0033] When the vehicle makes a small turn, because the θ angle is smaller than the λ angle, in this state, the field o...

Embodiment 2

[0035] Such as Figure 5 with Figure 7 As shown, this situation is a further improvement of Embodiment 1. The angle formed by the axis of the tractor and the centerline of the semi-trailer is θ, and the line connecting the center of the probe 9 and the center of the saddle 7 is connected to the centerline of the tractor 6. The angle formed between them is the λ angle; when the vehicle turns to the right front direction and the θ angle is greater than the λ angle, the shift lever 13 is in the forward gear at this time, and the signal received by the control device 11 is still a non-reversing signal, and the rear of the semi-trailer 1 The left and right cameras 5 on the sides are still facing the front of the vehicle. The difference from Embodiment 1 is that the control device 11 controls the display to display the picture of the right camera 5 in full screen. The picture on the right side of the vehicle is relatively enlarged, so that the situation in the inner wheel differen...

Embodiment 3

[0038] Such as Figure 5 with Figure 8 As shown, the angle formed by the axis of the tractor and the center line of the semi-trailer is θ, and the angle formed between the line connecting the probe 9 and the center of the saddle 7 and the center line of the tractor 6 is λ; when the semi-trailer When the trailer is reversing to the right rear direction, the θ angle is greater than or equal to 0 degrees, the shift lever 13 is in the reverse gear, and the signal transmitted from the reversing sensor 10 to the control device 11 is a reversing signal. The control device 11 will give a command to the motor 2 at the right rear of the vehicle, so that the right motor 2 drives the right camera 5 towards the rear of the vehicle. At this time, the right camera 5 can capture the picture directly behind the semi-trailer 1 . At the same time, the control device 11 controls the left motor 2 to drive the left camera 5 towards the front of the vehicle. At this time, the left camera 5 capture...

Abstract

The invention refers to an automobile security monitoring field, and in particular to a multifunctional visual system used for a semitrailer and a working method thereof. The multifunctional visual system used for the semitrailer comprises the semitrailer, a motor, a camera, a probe and an angle sensor, wherein a lower surface of the front part of the semitrailer is provided with the angle sensor; a saddle is arranged below the semitrailer located at the rear part of the angle sensor; the left and right sides at the front part of the saddle are respectively provided with one probe; an angle of Theta is formed between the probe and the center line of the semitrailer; the left and right sides at the tail part of the semitrailer are respectively provided with a base; a vertical plane of the base is fixed at the side of the semitrailer; the base is provided with the motor; the outer side of the motor is connected with a support through a rotor of the motor; the support is provided with the camera. Compared with the prior art, the invention can effectively eliminate the problem of the sight dead zone of a semitrailer driver and have the visual field when the semitrailer is in reverse, so that the driver can grasp the surrounding state of the semitrailer in all directions, and the potential safety hazard due to the difference of radius between inner wheels and the sight dead zone can be reduced.

Description

technical field [0001] The invention relates to the field of automobile safety monitoring, in particular to a multifunctional visual system for a semi-trailer and a working method thereof. Background technique [0002] For semi-trailer vehicles, the inner wheel differential is the difference in turning radius between the inner front wheels of the tractor and the inner rear wheels of the semi-trailer. Since the length of the semi-trailer compartment of the semi-trailer is generally more than ten meters or more, the value of the inner wheel difference is generally relatively large, up to more than 2 meters. Moreover, it involves the cooperation of the tractor and the semi-trailer, so in the driving state, the blind spot of the driver's vision is large, and it is difficult to fully control the state of the vehicle. In addition, the problem of inner wheel difference will form a safety hazard caused by the problem of vision. Contents of the invention [0003] In order to overc...
