[0006] S2. The vehicle rescue vehicle lifts up the vehicle to be rescued, and when the four wheels of the vehicle to be rescued are off the ground, the vehicle rescue vehicle tows the vehicle to be rescued to the emergency lane.

[0007] In some embodiments, the operator remotely controls the drive motor on the front axle of the vehicle recovery vehicle, and the drive motor drives the two front wheels to rotate forward.

[0008] In some embodiments, the vehicle recovery vehicle movement mode is forward unidirectional driving.

[0009] In some embodiments, after the vehicle rescue vehicle moves to the bottom of the vehicle to be rescued, the wheelbase and track of the vehicle rescue vehicle are adjusted to make the jack on the top of the vehicle rescue vehicle correspond to the chassis of the vehicle to be rescued.

[0010] In some embodiments, there are four jacks, which respectively correspond to the four wheels of the vehicle rescue vehicle and are arranged on the top of the vehicle rescue vehicle.

[0011] In some embodiments, the four jacks are connected in parallel, and after power is supplied, the four jacks rise or fall simultaneously.

[0012] In some embodiments, the two front wheels turn differentially.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] As mentioned in the background technology, with the rapid development of the automobile industry and the surge in the number of vehicles, vehicle breakdowns and traffic accidents on highways have occurred frequently, becoming one of the main factors affecting traffic safety and smooth roads. Traditional vehicle rescue methods mostly rely on manual on-site operations, which are not only time-consuming, but also operate in high-risk environments such as highways, which can easily pose a safety threat to rescue personnel. At the same time, it may also aggravate traffic congestion and even cause secondary accidents. Therefore, it is particularly urgent to develop a vehicle rescue technology that can improve rescue efficiency, ensure personnel safety, and reduce traffic impacts.

[0026] In order to improve the above problems, the present application proposes a method for controlling a vehicle rescue trailer. Through remote control, the operator can control the rescue vehicle in a safe position, respond to rescue needs quickly, and reduce the time to arrive at the scene. The operator does not need to perform manual operations on dangerous highways, which reduces the safety risks at work. Since the rescue process is faster, the faulty vehicle can be moved to the emergency lane faster, thereby alleviating traffic jams caused by rescue. By accurately controlling the jack and adjusting the wheelbase and track, the smooth lifting of the rescue vehicle is ensured to reduce the possibility of secondary damage. The use of cameras and image sensors to assist in determining the corresponding relationship between the jack and the chassis of the rescued vehicle improves the accuracy and reliability of the rescue. The design of the solid rubber wheel enables the vehicle rescue vehicle to adapt to a variety of ground conditions and improves the operating ability in different environments. The parallel design of the jack system can achieve synchronous lifting, simplify the operation process, and improve the operating efficiency. The drive motor and differential turning function on the front axle make the vehicle rescue vehicle have good maneuverability and can be flexibly operated under narrow or complex road conditions. The application of two-way video transmission and environmental perception system enables operators to monitor the situation at the rescue site in real time and make timely adjustments. The intelligent design of the entire system helps to improve the overall quality and effectiveness of rescue and provide car owners with a better service experience.

[0027] See also Figure 1 As shown, a vehicle rescue trailer control method according to an embodiment of the present application includes the following steps:

[0028] S1. The operator remotely controls the vehicle rescue vehicle to move the vehicle rescue vehicle to the bottom of the vehicle to be rescued;

[0029] S2. The vehicle rescue vehicle lifts up the vehicle to be rescued, and when the four wheels of the vehicle to be rescued are off the ground, the vehicle rescue vehicle tows the vehicle to be rescued to the emergency lane.

[0030] In some specific embodiments, an operator remotely controls a drive motor on the front axle of the vehicle recovery vehicle, and the drive motor drives the two front wheels to rotate forward.

[0031] In some specific embodiments, the vehicle recovery vehicle movement mode is forward unidirectional driving.

[0032] Specifically, the forward one-way driving mode simplifies the operation process, allowing rescuers to quickly move the vehicle rescue vehicle to the bottom of the vehicle to be rescued, thereby speeding up the overall rescue speed. Due to the simple operation, the waiting time during the rescue process is greatly shortened, which helps to restore traffic order faster. The operation of the forward one-way driving mode is relatively simple and intuitive, and rescuers do not need to make complex changes or adjustments, which reduces the difficulty of operation and the error rate. Rescuers can focus more on the road conditions ahead and control the movement of the vehicle rescue vehicle through simple acceleration and deceleration, which improves the convenience and accuracy of operation. On highways, frequent lane changes increase the risk of traffic accidents. The forward one-way driving mode reduces the need for lane changes during the rescue process, thereby reducing potential safety risks. Since only the forward direction needs to be paid attention to, the vehicle rescue vehicle can maintain a more stable driving state, which helps to avoid secondary accidents caused by sudden changes in direction or emergency braking. Highways usually have long straight sections and fewer intersections, which provides an ideal application scenario for the forward one-way driving mode. In this environment, the rescue vehicle can move quickly and stably to the location of the vehicle to be rescued. The traffic volume on highways is large, and frequent lane changes and U-turns will aggravate traffic congestion. The forward one-way driving mode reduces interference with traffic flow by simplifying the operation process, helping to ease congestion. The forward one-way driving mode has significant advantages in highway vehicle rescue. It not only improves rescue efficiency and operational convenience, but also enhances safety and adapts to the special environment of highways.

[0033] In some specific embodiments, after the vehicle rescue vehicle moves to the bottom of the vehicle to be rescued, the wheelbase and track of the vehicle rescue vehicle are adjusted to make the jack on the top of the vehicle rescue vehicle correspond to the chassis of the vehicle to be rescued.

[0034] Specifically, adjusting the wheelbase and track width allows the vehicle rescue vehicle to support the vehicle to be rescued more stably. This stability helps prevent rollover or slippage caused by unstable center of gravity during the jacking process, thereby ensuring the safety of the rescue operation. The stable support platform provides a solid foundation for the jack, making the jacking process more stable and controllable. By accurately adjusting the wheelbase and track width, it can be ensured that the jack acts accurately on the key position of the chassis of the vehicle to be rescued. This helps to avoid unnecessary damage to the bottom of the vehicle and reduce the risk of secondary accidents caused by improper operation. The stable support structure also reduces the possibility of injury to rescue personnel during the operation and improves the safety of the overall rescue. When the wheelbase and track width of the vehicle rescue vehicle perfectly correspond to the chassis of the vehicle to be rescued, rescuers can complete the jacking operation faster. This efficient operation process shortens the rescue time and helps to restore traffic order as soon as possible. Precise adjustment reduces the time wasted by trying different positions and improves the efficiency of the rescue work. Different models have different chassis structures and sizes. By adjusting the wheelbase and track width of the vehicle rescue vehicle, it can be adapted to a wider variety of vehicles to be rescued. This flexibility enables the same rescue vehicle to handle more types of rescue missions, improving the utilization of rescue resources. By adjusting the wheelbase and track of the vehicle rescue vehicle so that the top jack corresponds to the chassis of the vehicle to be rescued, it has significant advantages in highway vehicle rescue. It not only improves the stability and safety of the rescue, but also improves the rescue efficiency and adapts to the needs of various vehicle models.

[0035] In some specific embodiments, four jacks are provided, and the four jacks respectively correspond to the four wheels of the vehicle rescue vehicle and are provided on the top of the vehicle rescue vehicle.

[0036] Specifically, four jacks correspond to four wheels, ensuring that each wheel is evenly supported when the vehicle is lifted. This evenly distributed support helps prevent the vehicle from tilting or tipping over during the lift, thereby improving overall stability. When the jacks are set on top of the vehicle rescue vehicle, they can form a stable support platform, making the rescue vehicle more stable and reliable when moving or lifting the vehicle. By precisely adjusting the position and height of the four jacks, the vehicle can be safely and stably lifted. This helps to avoid vehicle damage or injuries caused by improper operation. Safety is the primary consideration when performing rescue on the highway. The design of the four jacks can provide additional safety and ensure that the rescue process goes smoothly. When the jacks are set on top of the vehicle rescue vehicle, rescuers can adjust the position and height of the jacks more conveniently and quickly. This helps to shorten the rescue time and improve the rescue efficiency.

[0037] In some specific embodiments, the four jacks are connected in parallel, and after power is turned on, the four jacks rise or fall simultaneously.

[0038] Specifically, four jacks are connected in parallel and can rise or fall at the same time after being powered on, so that the rescue vehicle can be lifted or lowered more quickly, thereby improving rescue efficiency. Four jacks are connected in parallel to ensure that the center of gravity of the vehicle is always kept between the four wheels when lifting or lowering the rescue vehicle, avoiding safety accidents such as rollover caused by the center of gravity shift. Four jacks are connected in parallel to evenly distribute the weight of the vehicle and avoid excessive pressure on a single jack, thereby reducing damage to the vehicle chassis and wheels. Four jacks are connected in parallel to adapt to the chassis structure of different models by adjusting the wheelbase and track, so that the vehicle rescue vehicle can cope with various types of faulty vehicles.

[0039] In some embodiments, the two front wheels turn differentially.

[0040] Specifically, by controlling the speed difference between the left and right drive wheels, differential turning technology enables the vehicle to achieve more flexible steering in narrow or complex terrain. This is especially important for vehicle rescue on highways, because rescue vehicles need to be able to move quickly in a limited space in order to approach the faulty vehicle and tow or repair it. In some cases, such as when driving at high speeds, the stability of the vehicle may be affected. However, differential turning technology can optimize the dynamic balance of the vehicle by adjusting the speed of the drive wheels, thereby reducing the instability caused by speed changes.

[0041] In some specific embodiments, a camera installed on the vehicle rescue vehicle is used to determine whether the four jacks correspond to the bottom plate of the vehicle to be rescued.

[0042] Specifically, through real-time monitoring by cameras, rescuers can ensure that the jack accurately acts on the key position of the chassis of the vehicle to be rescued. This helps to avoid vehicle damage or personal injury caused by improper operation. The visual feedback provided by the camera can help rescuers adjust the position and height of the jack in time to ensure the safety of the rescue process. Using the camera to quickly determine the correspondence between the jack and the floor of the vehicle to be rescued can shorten the rescue time. Rescuers do not need to get off the vehicle to check in person, they can make accurate judgments by observing through the camera. This efficient operation method helps to improve the overall rescue efficiency, especially in emergency situations, and can move the vehicle to be rescued to a safe location faster. As a remote monitoring tool, the camera provides rescuers with a convenient operation method. They can observe the working status of the jack through the monitoring screen in the cab without having to get off the vehicle frequently for inspection.

[0043] In some specific embodiments, all four wheels of the vehicle recovery vehicle are solid rubber wheels.

[0044] Specifically, solid rubber wheels provide better support and stability due to their structural characteristics. This stability helps prevent the rescue vehicle from tilting or shaking when lifting the vehicle to be rescued, ensuring the smooth progress of the rescue process. The stable wheel design also makes the rescue vehicle more stable during movement, reducing the risk of vehicle loss of control due to uneven road conditions or emergencies. Solid rubber wheels are more resistant to wear and punctures than pneumatic tires. In complex road conditions such as highways, solid wheels can better cope with various sharp objects and harsh environments, extending the service life of the rescue vehicle. Improved durability also means that the rescue vehicle requires less maintenance and replacement of parts, reducing long-term operating costs. Solid rubber wheels do not pose a risk of tire blowouts during driving.

[0045] In some specific embodiments, the ground clearance of the wheels of the vehicle to be rescued is checked by an image sensor disposed on a vehicle rescue vehicle.

[0046] Specifically, image sensors can quickly and accurately check the ground clearance of the wheels of the vehicle to be rescued, reducing the time and error of manual measurement. With real-time data transmission, rescuers can quickly assess the status of the vehicle and develop more efficient rescue plans. Using image sensors for remote detection can prevent rescuers from directly contacting the dangerous area under the vehicle and reduce the risk of secondary injuries caused by improper operation. At the same time, sensor data provides a reliable basis for rescue decisions and ensures the safety of each step. Image sensors have the characteristics of high resolution and high precision, and can capture subtle changes in wheel ground clearance. This high-precision data helps rescuers make more accurate judgments, so as to take the most appropriate rescue measures and avoid potential risks caused by misjudgment. Image sensors are suitable for various complex environments and can work normally in low light or small spaces. Its flexible installation method and strong adaptability make vehicle rescue in different scenarios such as highways more efficient and convenient. The data collected by image sensors can not only be used for immediate rescue, but also stored and analyzed to provide reference for similar situations in the future. These data help optimize the rescue process, improve the overall rescue level, and provide a scientific basis for accident cause analysis.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
