[0003] 1. Autonomous Driving Technology: The core of the unmanned target vehicle's directional control system lies in autonomous driving technology, which involves path planning, positioning and navigation, and vehicle control. Currently, autonomous driving technology mainly relies on vision, lidar, and GPS navigation technologies.

[0004] 2. Sensor Technology: To achieve environmental perception, the unmanned target vehicle's steering control system needs to be equipped with a variety of sensors, such as cameras, lidar, and ultrasonic sensors.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1:

[0027] See also Figure 1 A direction control device for an unmanned target vehicle includes a motor assembly 1. The output shaft of the motor assembly 1 is connected to a steering mechanism 2. The other end of the steering mechanism 2 is provided with a fixed plate 3. A fixed assembly is provided on the fixed plate 3. The fixed plate 3 is used to connect to the steering wheel. The motor assembly 1 is fixedly installed inside the target vehicle.

[0028] The motor assembly 1 includes a controller and a motor. The controller is electrically connected to the motor. The controller is used to control the forward and reverse rotation of the motor. The controller is also provided with a positioning module and a route correction module that are electrically connected to each other. The positioning module is used to obtain the current position of the target vehicle. The route correction module is used to compare the current position of the target vehicle with the target position of the target vehicle to obtain the deviation value of the current position of the target vehicle, and control the forward and reverse rotation of the direction motor through the PID algorithm, thereby realizing the correction of the position of the contour-profiling target vehicle so that it always moves along the target route.

[0029] The steering mechanism 2 includes a steering column 202 and two universal joints 201. The two ends of the steering column 202 are connected to the two universal joints 201. The motor assembly 1 drives the steering mechanism 2, thereby driving the steering wheel of the target vehicle. The output shaft of the motor assembly 1 is connected to one of the universal joints 201, while the other universal joint 201 is connected to the fixed plate 3. The motor assembly 1 drives the connected universal joints 201 to rotate. The rotation of the universal joint 201 at one end drives the steering column 202. The steering column 202 drives the universal joint 201 at the other end. The universal joint 201 at the other end drives the fixed plate 3, thereby rotating the steering wheel connected to the fixed plate 3.

[0030] Among them, the fixing component is a bolt, a mounting hole is opened on the fixing plate 3, the bolt is threadedly matched with the mounting hole, and a threaded hole matching the bolt is opened on the steering wheel of the target vehicle. The fixing plate 3 and the steering wheel are fixed by bolts, and can also be fixed by bolts and nuts.

[0031] When the utility model is in use, the steering is turned to the right when the motor rotates clockwise, and the steering is turned to the left when the motor rotates counterclockwise; during automatic driving, the controller obtains the current position of the target vehicle through differential GPS, and uses the deviation value of the current position of the contour-profiling target vehicle obtained by comparing the current position of the contour-profiling target vehicle with the driving target position, and controls the forward and reverse rotation of the steering motor through the PID algorithm, thereby realizing the correction of the position of the contour-profiling target vehicle, so that it always moves along the target route.

[0032] Example 2:

[0033] See also Figure 2-4 , which is different from the first embodiment in that: a mounting cavity 301 is formed on the fixed plate 3, and the fixing assembly includes two clamping plates 4 arranged opposite to each other. The clamping plates 4 are located in the mounting cavity 301, and the mounting cavities 301 are extended at both ends. The clamping plates 4 are slidably engaged with the mounting cavities 301. The two clamping plates 4 can move relative to each other along the length direction of the mounting cavity 301, thereby clamping the steering wheel. That is, the two clamping plates 4 clamp the spokes of the steering wheel to achieve fixation between the steering wheel and the fixed plate 3;

[0034] An adjusting rod 5 is provided between the two splints 4. Two threaded sections with opposite thread directions are relatively provided on the adjusting rod 5. The threaded sections are threadedly connected to the splint 4. Supports are provided at both ends of the adjusting rod 5. The adjusting rod 5 is rotatably connected to the supports. By rotating the adjusting rod 5, the two splints 4 can move relative to each other. The mounting cavity 301 limits the moving trajectory of the splint 4, so that the splint 4 can only move in a straight line along the length direction of the mounting cavity 301.

[0035] In a possible embodiment, a locking structure is provided on the support at the end of the adjusting rod 5, and the locking structure includes a sleeve and a pin. The sleeve is sleeved on the adjusting rod 5 and there is a gap between the sleeve and the adjusting rod 5. A plurality of pin holes are provided on the adjusting rod 5. When the splint 4 clamps the spokes, the pins are sequentially extended through the sleeve to the pin holes to achieve locking of the adjusting rod 5 and prevent the adjusting rod 5 from rotating when accidentally touched.

[0036] In this application, limiting plates 6 are set on both sides of the installation cavity 301. The limiting plates 6 pass through the two clamps 4 in sequence. The clamps 4 slide together with the limiting plates 6. The position of the clamps 4 is further limited by the setting of the limiting plates 6, so that the moving trajectory of the clamps 4 is stable.

[0037] In this application Figure 4 As shown in the figure, a groove is provided at one end of the splint 4 away from the adjusting rod 5, and a spring telescopic rod is provided in the groove. The end of the spring telescopic rod is connected to a baffle 7, which slides in cooperation with the groove. The baffle 7 is an L-shaped structure. The outer side surface of the spoke can be clamped by setting the baffle 7. The baffle 7 is pulled outward and the spring telescopic rod is used to provide tension so that the outer side surface of the spoke abuts against the horizontal part of the outer end of the baffle 7, thereby improving the stability and tightness of the fixation of the splint 4.

[0038] In this embodiment, when the fixing plate 3 is connected to the steering wheel of the target vehicle, the fixing assembly is aligned with the spokes on the steering wheel so that the spokes are located between the two clamping plates 4. Then, the adjusting rod 5 is rotated to make the two clamping plates 4 relatively close to each other, and then the baffle 7 is pulled outward so that the inner side of the baffle 7 contacts the outer side of the spokes. The adjusting rod 5 is continued to be rotated until the two clamping plates 4 clamp the spokes of the steering wheel of the target vehicle, and finally the adjusting rod 5 is locked.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
