[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: A remotely controllable target vehicle control system based on an automatic transmission vehicle includes an automatic brake release system, a start-stop system, a shifting system, an acceleration / deceleration system, a steering system, and a camera system that are electrically connected to a handheld control terminal.

[0021] Through the cooperation of various systems such as the automatic brake release system, the start-stop system, the shifting system, the acceleration / deceleration system, the steering system, and the camera system, etc., the flexibility of the target vehicle can be adapted to the requirements.

[0022] As a preferred embodiment in this embodiment, as Figure 1-9 shown, the acceleration / deceleration system includes two arc-shaped bars 7 with arc-shaped chutes, two first screws 11 threadedly installed with first ball nuts 14, two rotating shafts 15 rotatably arranged on a plate body 13, and a second screw 19 installed with a second ball nut; The two first screws 11 are rotatably arranged on the plate body 13 at the upper end of the chassis 1. The ends of the two first screws 11 are respectively engaged with the corresponding rotating shafts 15 through bevel gears. Driving gears 16 are installed at the other ends of the two rotating shafts 15; The second screw 19 is rotatably arranged on the plate body 13. One end of the second screw 19 is engaged with a driving motor 21 on the plate body 13 through a bevel gear. The second ball nut is fixedly embedded on a toothed plate 17. Two racks 18 are arranged at left and right intervals on the toothed plate 17. The racks 18 are composed of a plurality of driving teeth arranged in a straight line. The two racks 18 are respectively located on one side of the corresponding driving gears 16; Arc-shaped sliders 8 are slidably arranged in the two arc-shaped chutes. Extrusion rods 9 and push rods 12 are respectively installed at both ends of the arc-shaped slider 8. The push rod 12 is connected to the first ball nut 14. Throttle pedal assembly blocks 20 and brake pedal assembly blocks 10 with receiving grooves are respectively movably installed at the lower ends of the two extrusion rods 9; The steering system includes an outer tube 22 on the rotating chassis 1, an inner tube 23 is slidably provided in the inner cavity of the outer tube 22, and a driving column 24 is fixed at the end of the inner tube 23, and an elastic sleeve with a rough surface is fixedly provided on the outer surface of the driving column 24, and a rotating shaft 27 is rotatably provided in the inner cavity of the outer tube 22, and the lower end of the rotating shaft 27 is connected to the output shaft of the rotating motor 25 at the bottom of the outer tube 22, and a spline 28 is installed on the upper end of the rotating shaft 27, and the spline 28 is located in the spline cavity of the inner tube 23, and the inner tube 23 is located on the outer wall of the inner cavity of the outer tube 22 and fixedly provided with a bearing 29, and positioning holes are provided on the outer wall of the bearing 29 and the inner tube 23, and a through hole is provided on the outer wall of the outer tube 22, and the outer tube 22 and the bearing 29 are fixed by bolts 26; The automatic brake release system comprises a first hollow cylinder 2 in which an electric telescopic rod is installed; The start-stop system comprises a second hollow cylinder 3 in which an electric telescopic rod is installed; The shifting system comprises a third hollow cylinder 4 with an electric telescopic rod installed inside, and an F-shaped push plate 5 is installed at the output end of the electric telescopic rod; The camera system includes a camera installed on the vehicle or the vehicle's own S60 panoramic view; The three sets of electric telescopic rods, the driving motor 21, the rotating motor 25 and the camera are all electrically connected to the controller 6 with a signal transceiver.

[0023] Understand the vehicle's driving conditions through the camera system, and use the handheld control terminal to control the coordination of various systems such as the automatic brake release system, start-stop system, gear shift system, acceleration and deceleration system, steering system, and camera system as needed; At the beginning, the first hollow cylinder 2, the second hollow cylinder 3 and the third hollow cylinder 4 are installed on the car by means of adhesive, so that the electric telescopic rod in the first hollow cylinder 2 is aligned with the start / stop button of the car, and the electric telescopic rod in the second hollow cylinder 3 is aligned with the brake unlocking button. During installation, the shift handle is located in the U-shaped cavity of the F-shaped push plate 5, and the F-shaped push plate 5 drives the shift handle to shift gears through the electric telescopic rod, mainly for switching between forward gears or reverse gears; The accelerator pedal assembly block 20 and the brake pedal assembly block 10 are assembled with the accelerator pedal and the brake pedal respectively, and the driving column 24 is in contact with the steering wheel. The driving column 24 and the steering wheel are squeezed by the component force of the gravity of the rotating motor 25. Whether it is an O-shaped or a D-shaped steering wheel, the driving column 24 can be closely attached to the steering wheel in real time; When accelerating or decelerating, the driving motor 21 can be controlled to work, driving the second screw 19 to rotate, so that the toothed plate 17 makes an extending movement and drives one group of rotating shafts 15 to rotate. This rotating shaft 15 can drive the first screw 11 connected to the throttle pedal assembly block 20 to rotate, and then the push rod 12 drives the throttle pedal assembly block 20 to move downward along the arc-shaped chute to press the throttle pedal, thereby accelerating the vehicle. When deceleration is required, the driving motor 21 is controlled to rotate in the reverse direction. At this time, the toothed plate 17 moves in the reverse direction, reducing the throttle to 0. The toothed plate 17 continues to rotate in the reverse direction. At this time, the other group of racks 17 drives the other group of rotating shafts 15 to rotate, and then the other group of push rods 12 pushes the brake pedal assembly block 10 to move downward for braking. After the vehicle body stops braking and shuts off the engine, the toothed plate 17 can be restored to its original position. At this time, all components also return to their original positions. By using a group of driving motors 25 and two racks 17 to control the throttle and brakes in a staggered tooth connection manner (directly pressing the brake pedal for braking after reducing the throttle to 0), the regulation of the throttle and brakes can be quickly achieved.

[0024] It should be noted that: First, the arc-shaped chute is consistent with the movement paths of the throttle pedal and the brake pedal; Second, the two ends of the arc-shaped slider 8 are respectively rotatably installed with a pressing rod 9 and a push rod 12; Third, the rotation point of the outer tube 22 is set as high as possible, which can form a labor-saving lever. With the weight of the rotating motor 25 unchanged, the upward movement of the rotation point can increase the tight contact strength between the driving column 24 and the steering wheel; Fourth, the handheld control end is electrically connected to the controller for remote control, and the controller is connected to the vehicle body power supply to provide electrical energy.

[0025] As a preferred implementation manner in this embodiment, a U-shaped plate 40 is fixed on the first ball nut 14, and universal balls are provided on the inner wall of the U-shaped plate 40. The lower end of the push rod 12 is located in the inner cavity of the U-shaped plate 40 and is in sliding contact with the universal balls. An arc-shaped opening 41 adapted to the movement path of the push rod 12 is provided at the upper end of the plate body 13.

[0026] Since at the main driver's position, the tops of the throttle and brake pedals are arc-shaped surfaces. When the push rod 12 drives the brake pedal assembly block 10 or the throttle pedal assembly block 20 to move downward, the push rod 12 will also move downward, which can prevent the upper end of the push rod 12 from contacting the arc-shaped surface to form an obstruction to the push rod or cause damage to the arc-shaped surface, and at the same time reduce the space occupied by the operation of this system.

[0027] As a preferred implementation manner in this embodiment, a close-fitting mechanism is further included for making the outer surface of the driving column 24 closely fit with the outer wall of the steering wheel.

[0028] As a preferred implementation manner in this embodiment, as Figure 6 、 Figure 8 and Figure 9As shown in the figure, the close - fitting mechanism is inclinedly arranged on the chassis 1, and the inclination angle of the close - fitting mechanism is the same as that of the steering wheel. The close - fitting mechanism includes a hollow tube 31 installed on the mounting plate 30. A square column 32 is slidably arranged in the inner cavity of the hollow tube 31. A compression spring 35 is installed at the lower end of the square column 32. The lower end of the compression spring 35 is fixed with a first contact plate, and balls are arranged on the first contact plate. The lower end of the outer tube 22 is fixed with a second contact plate. A third screw 34 is rotatably arranged in the inner cavity of the hollow tube 31, and the lower end of the third screw 34 is threadedly connected in the threaded connection of the square column 32. An elastic damping ring 33 is arranged between the outer wall of the third screw 34 and the inner wall of the hollow tube 31.

[0029] When the driving column 24 is in close contact with the outer wall of the steering wheel, by rotating the third screw 34, the first contact plate can be made to contact and compress the fastening spring 38 with the second contact plate. Through the elastic force of the fastening spring 38, the extrusion effect between the driving column 24 and the steering wheel can be further improved, preventing the driving column 24 from separating from the steering wheel when driving on a bumpy road or a vehicle jolts. Since the steering wheel is divided into O - shaped and D - shaped, for the D - shaped steering wheel, compared with the O - shaped one, the rotating motor 25 will deflect counterclockwise by a certain angle, and correspondingly, the fastening spring 38 will extend by a certain distance, but still keep the driving column 24 in close contact with the outer surface of the steering wheel. Therefore, this close - fitting mechanism is beneficial to the close contact between the driving column 24 and the steering wheel, avoiding the separation of the driving column 24 from the steering wheel during driving on a bumpy road and thus affecting the real - time control of the steering wheel.

[0030] As a preferred implementation manner in this embodiment, it further includes a fastening mechanism for stably and firmly installing the chassis 1 on the carrier vehicle.

[0031] As a preferred implementation manner in this embodiment, as Figure 10 shown, multiple groups of fastening mechanisms are arranged vertically and horizontally. The fastening mechanism includes a bidirectional screw 36 with fastening rods 37 threadedly sleeved at both ends thereof, and the bidirectional screw 36 is rotatably arranged in the chassis 1. Both fastening rods 37 are fixedly penetrated through the chassis 1 and are connected to the positioning plate 39 through the fastening spring 38.

[0032] During use, by rotating the bidirectional screw 36, the two fastening rods 37 can extend outwards to contact the vehicle body, thereby realizing the fixation of the chassis 1. Through multiple vertical and horizontal fastening mechanisms, the stable fixation of the chassis 1 can be achieved, and the relative displacement between the chassis 1 and the vehicle body during driving on a bumpy road can be avoided, thus preventing the influence on the control of the vehicle body.

[0033] As a preferred implementation manner in this embodiment, the fastening spring 38 is connected to the positioning plate 39 through a universal ball.

[0034] This enables the positioning plate 39 to change the angle relative to the fastening rod 37, which is more conducive to the fitting of the contact surface between the positioning plate 39 and the vehicle body, thereby increasing the fixing effect.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
