[0022] The method embodiment can be executed in an electronic device or similar computing device in a vehicle including a memory and a processor. For example, Figure 1As shown, the electronic device of the vehicle may include one or more processors 102 (the processor may include but is not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a field programmable logic device (FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data. Optionally, the electronic device of the above-mentioned car may also include a transmission device 106 for communication functions, an input and output device 108, and a display device 110. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the electronic device of the vehicle. For example, the electronic device of the vehicle may include more or fewer components than those described in the above structure, or may have a configuration different from that described in the above structure.

[0023] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the trailer axle load control method of the new energy powered trailer in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the trailer axle load control method of the new energy powered trailer described above is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0024] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0025] The display device 110 may be, for example, a touch screen type liquid crystal display (LCD) and a touch display (also referred to as a "touch screen" or a "touch display screen"). The liquid crystal display may enable a user to interact with a user interface of the mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), and a user may interact with the GUI by finger contact and / or gestures on a touch-sensitive surface, wherein the human-computer interaction functions here may optionally include the following interactions: creating web pages, drawing, word processing, making electronic documents, games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music and / or web browsing, etc. The executable instructions for executing the above human-computer interaction functions are configured / stored in a computer program product or a readable storage medium executable by one or more processors.

[0026] When the vehicle is stationary, the static load on each axle is equal to the weight of the axle and the body and cargo it supports. During the operation of the vehicle, it is also subject to dynamic loads. During the vehicle's driving, the axle load will change due to dynamic conditions such as acceleration, deceleration, and turning. For example, when the vehicle accelerates, the load on the drive axle increases; when braking, the load on the brake axle increases.

[0027] Load distribution: refers to the distribution of load on each axle of the vehicle. Ideal load distribution can provide the best vehicle handling and stability.

[0028] Load Transfer: When a vehicle accelerates, brakes or turns, loads are transferred between the axles of the vehicle due to inertial forces.

[0029] In the prior art, the shaft load is adjusted mainly by the following methods:

[0030] 1. Cargo redistribution: Ensure that the cargo is evenly distributed in the trailer to avoid load concentration on a certain axle. When loading cargo, the axle load can be redistributed by adjusting the position of the cargo.

[0031] 2. Axle load transfer technology. Axle load transfer technology includes lifting axle technology: on a multi-axle trailer, the axle with no load or less load can be lifted to reduce the load on the axle and increase the load on other axles. Skid steering: When turning, the axle load can be temporarily transferred through skid steering technology to improve the vehicle's handling.

[0032] The absence of a trailer drive system may result in limitations in terms of traction, braking performance, maneuverability, energy consumption and load distribution. Specifically, without the trailer's own drive system, it is not possible to adjust the trailer's axle loads through its motors. For example, increasing the traction of the trailer's drive axles can increase the load on these axles and reduce the load on the tractor's drive axles, thereby achieving a more balanced load distribution.

[0033] During driving, especially during cornering or evasive maneuvers, it is not possible to dynamically adjust the axle loads via the trailer's drive system to achieve optimal handling and stability.

[0034] When accelerating or braking, the trailer's weight transfer cannot be controlled by the trailer's own powertrain, which can result in uneven load distribution between the tractor and trailer.

[0035] Figure 2 is a method according to an embodiment of the present invention, such as Figure 2 As shown, the method comprises the following steps:

[0036] Step S10, obtaining vehicle condition information, the vehicle condition information including load information and acceleration information, the load information including the load on the axle of the trailer, and the acceleration information including the lateral acceleration and longitudinal acceleration of the trailer;

[0037] Step S20, determining the axle load distribution information of the trailer based on the vehicle condition information;

[0038] Step S30, generating a control instruction based on the axle load distribution information, wherein the control instruction is used to adjust the working parameters of the target components, and the target components include: a trailer drive motor, a TEBS electromagnetic relay valve, and a suspension system.

[0039] Through the above steps, the axle load distribution information of the trailer is determined based on the vehicle condition information, and control instructions are generated based on the axle load distribution information to adjust the working parameters of the target components, thereby achieving the purpose of adjusting the axle load distribution of the trailer, thereby achieving the technical effect of improving vehicle stability, and further solving the technical problem of poor vehicle stability caused by trailer axle load transfer.

[0040] By adjusting the output of the target component, the force distribution of the vehicle is actually adjusted dynamically, thereby affecting the axle load. This adjustment helps optimize the performance of the vehicle, prevents overloading of a certain axle, and ensures the safety and efficiency of the vehicle.

[0041] With the above-mentioned technical solution, each axle of the trailer is equipped with a drive motor, and each drive wheel of the trailer is equipped with a drive motor. These motors can directly provide power to the trailer to enhance traction. Each drive motor is electrically connected to a power battery to power the drive motor. The power battery provides electrical energy, so that the trailer motor can provide additional driving force when needed.

[0042] The trailer driving system includes an acquisition unit for acquiring the standard acceleration data and current acceleration of the tractor. The calculation unit is used to determine whether the current acceleration is less than the standard acceleration data of the tractor, thereby determining whether to start the trailer power assist mode.

[0043] When the trailer drive system determines that the current acceleration is less than the standard acceleration of the tractor, the trailer power-assist mode is activated and the drive motor works to increase the friction of the drive wheels.

[0044] In the event of emergency braking, the power battery supplies power to the drive motor, which reverses and provides braking force for the drive wheels. At the same time, the drive motor can act as a generator when reversing to charge the battery and achieve energy recovery.

[0045] The trailer control system includes four operating modes, including trailer energy recovery mode, trailer auxiliary driving mode, trailer differential steering mode and trailer mixed braking mode. These modes work together to improve the maneuverability of the tractor and trailer and provide additional braking force when necessary.

[0046] The drive motor can provide additional traction for the trailer, especially when starting, climbing or overloading, improving the overall vehicle transportation efficiency. The motor can be used as a generator during braking to achieve energy recovery, reduce the thermal load of the braking system, and improve braking efficiency and safety. The combination of the motor's precise control capability and the TEBS system can provide more precise control for autonomous driving and achieve safer autonomous driving functions.

[0047] Optional, Electronically Controlled Braking System (TEBS) is an electronically controlled braking system for trailers. Compared with the traditional pneumatic braking system, the electronically controlled braking system uses electric control air instead of pneumatic control air to improve braking efficiency and response speed.

[0048] TEBS solenoid relay valve: As the core component of the electronically controlled braking system, the TEBS solenoid relay valve is equipped with control electronics with a tractor CAN interface, including an axle load pressure sensor, a brake chamber pressure sensor, an internal pressure sensor, and a lateral acceleration sensor.

[0049] TEBS is suitable for a variety of suspension and brake types. When installing, make sure that the vehicle is on a level surface to ensure the accurate and normal operation of the rollover protection function (RSS). The backup valve of the EBS electromagnetic relay valve isolates the control pressure and the control line during normal operation. When a TEBS failure occurs, the control pressure reaches the brake chamber directly through the control line to ensure the ABS function as much as possible.

[0050] Through the cooperation of the motor and TEBS system, more intelligent load distribution can be achieved, improving the stability and passability of the vehicle.

[0051] Optionally, generating a control instruction based on the shaft load distribution information includes:

[0052] Acquire a load distribution model and driving information, wherein the load distribution model is used to determine distribution information according to the axle load distribution information and the driving information, the distribution information includes an optimal load distribution result of the trailer, and the driving information includes at least a driving operation;

[0053] That is to say, based on the real-time load data, the VCU can apply the load distribution algorithm to determine whether the load distribution needs to be adjusted. When calculating the axle load distribution through the load distribution algorithm, the driver's driving operation should also be considered. For example, when the driver performs a turning operation, under the turning condition, based on the output result of the load distribution model, the load on the outer axle needs to be increased to improve stability. The axle load can be dynamically adjusted by controlling the output torque of the motor to optimize the vehicle's handling and stability.

[0054] A control instruction is generated based on the allocation information.

[0055] Optionally, generating a control instruction based on the shaft load distribution information includes:

[0056] Obtaining a load distribution model and road information, wherein the load distribution model is used to determine distribution information according to the axle load distribution information and the road information, the distribution information includes an optimal load distribution result of the trailer, and the road information includes at least a road environment of a vehicle driving area;

[0057] That is to say, based on the real-time load data, the VCU can apply the load distribution algorithm to determine whether the load distribution needs to be adjusted. When calculating the axle load distribution through the load distribution algorithm, the road environment should also be considered. For example, when the vehicle is driving on a climbing section, based on the output results of the load distribution model, the axle load of the axle closer to the tractor needs to be increased relative to the axle farther away from the tractor, which can lower the center of gravity of the trailer and improve the stability of the vehicle, which is conducive to improving the stability of the vehicle during the climbing process.

[0058] A control instruction is generated based on the allocation information.

[0059] Optionally, generating a control instruction based on the shaft load distribution information includes:

[0060] Obtaining a load distribution model and load information, wherein the load distribution model is used to determine distribution information according to the axle load distribution information and the load information, the distribution information includes an optimal load distribution result of the trailer, and the load information includes at least the weight of the trailer;

[0061] A control instruction is generated based on the allocation information.

[0062] That is to say, based on real-time load data, VCU can apply a load distribution algorithm to determine whether the load distribution needs to be adjusted. When calculating the axle load distribution through the load distribution algorithm, load information should also be considered. For example, when the trailer load exceeds the preset value, based on the output result of the load distribution model, the axle load of the axle farther away from the tractor needs to be increased relative to the axle closer to the tractor. This can increase the traction of the tractor, thereby improving the energy efficiency of the trailer and improving the handling. VCU sends control instructions to the motor controller and TEBS system to execute the load distribution strategy. The system monitors the vehicle status and environmental changes in real time and adjusts the control strategy based on feedback.

[0063] Optionally, if the load on a particular axle is found to be too high or too low, the VCU can make adjustments through the motor control system or suspension system to optimize load distribution.

[0064] Optionally, obtaining vehicle condition information includes:

[0065] Obtaining load information through a load sensor, wherein there are multiple load sensors, and the multiple load sensors are respectively arranged on each axis;

[0066] The acceleration information is obtained through the acceleration sensor.

[0067] Load sensors are installed on each axle of the trailer to monitor the load distribution of each axle in real time.

[0068] Acceleration sensors are installed on tractors and trailers to monitor the dynamic acceleration and deceleration of the vehicle. Lateral acceleration sensors monitor the lateral acceleration of the vehicle and are used to assess the lateral stability of the vehicle.

[0069] Acquiring vehicle condition information also includes load data processing and vehicle dynamics analysis: the data from the load sensor is input into the vehicle control unit (VCU), which analyzes the load distribution and determines whether adjustments are needed. Vehicle dynamics analysis: Combining the data from the acceleration sensor and the lateral acceleration sensor, the VCU evaluates the dynamic stability of the vehicle.

[0070] Optionally, after determining the axle load distribution information of the trailer based on the vehicle condition information, the method includes:

[0071] The shaft load distribution information is displayed in a visual form through the human-machine interactive interface.

[0072] Optionally, the operating parameters of the trailer drive motor include: motor output torque, and / or, the operating parameters of the TEBS electromagnetic relay valve include: valve opening value of the TEBS electromagnetic relay valve, and / or, the operating parameters of the suspension system include: air pressure or oil pressure of the suspension system.

[0073] The height of the vehicle is changed by adjusting the air pressure in the air suspension system, which affects the distribution of axle loads. The height of the vehicle and the load distribution are changed by adjusting the oil pressure in the hydraulic suspension system.

[0074] In an optional embodiment, determining the load on each axle of the trailer generally involves the following steps:

[0075] 1. Install load sensors: Install load sensors (such as weighing sensors or pressure sensors) on each axle of the trailer to monitor the load of each axle in real time. The sensors can be implemented through strain gauges or piezoelectric technology.

[0076] 2. Data acquisition: The real-time data of each sensor is transmitted to the vehicle control unit (VCU) through the data acquisition system. The VCU will read the data regularly for analysis and processing.

[0077] 3. Calculate shaft load: Based on the output signal of the sensor, VCU calculates the actual load of each shaft. Usually, the load sensor outputs an electrical signal proportional to the shaft load, and VCU converts it into the actual load value through calibration and conversion algorithms.

[0078] 4. Dynamic monitoring: During driving, the VCU continuously monitors the load changes of each axle, takes into account the dynamic state of the vehicle (such as acceleration, deceleration, steering, etc.), and updates the load data in real time.

[0079] 5. Load distribution algorithm: Based on the real-time load data and the vehicle's driving status, the VCU can apply the load distribution algorithm to determine whether the load distribution needs to be adjusted.

[0080] Intelligent load distribution ensures that the trailer maintains good stability and maneuverability under various driving conditions through real-time monitoring and dynamic adjustment. By installing load sensors and combining data analysis, the load on each axle can be accurately determined, thus achieving more efficient and safe transportation.

[0081] As an optional implementation, the system optimizes the control strategy based on historical data and driving habits through machine learning algorithms. Remote update: Remotely update the control algorithm and software of the VCU via wireless networks to adapt to new regulations and technological developments. Through the above control method, the motor and TEBS system can be coordinated to intelligently distribute the load, improve the stability and passability of the vehicle, and thus improve the overall transportation efficiency and safety.

[0082] Optionally, suspension system adjustment: by adjusting the air bags or oil pressure in the air suspension or hydraulic suspension system, the load on each axle can be changed. If the trailer is equipped with auxiliary drive motors, the VCU can control the output of the motors to help adjust the load distribution.

[0083] Optionally, the drive motor on the trailer can provide additional traction during starting, climbing or heavy load situations, increase the load on the drive axle, improve traction and vehicle stability. During braking, the drive motor on the trailer can work as a generator, converting kinetic energy into electrical energy and storing it back in the battery. This process can reduce the burden on the tractor's braking system while increasing the load on the trailer axle. When turning or on different road conditions, the axle load can be dynamically adjusted by controlling the output torque of the motor to optimize the vehicle's handling and stability. When turning, the drive motor on the trailer can control the speed of different axles to achieve differential steering, which helps redistribute axle loads when turning and reduces tire wear. Integrate the drive motor with the air suspension system to adjust the height of the vehicle by changing the air pressure of the airbags, thereby changing the axle load.

[0084] When the motor provides additional traction, it can increase the load on the drive axle because the motor's output force acts on the ground through the tires, thereby increasing the friction between the tires and the ground, which causes more of the vehicle's weight to be transferred to the drive axle.

[0085] During braking, the electric motor can recover energy by acting as a generator. This reduces the use of conventional braking systems, thereby reducing the braking force on the braked axle, which may increase the load on other axles (such as the drive axle) because the vehicle's momentum is used to generate electricity rather than being fully converted into heat energy.

[0086] In dynamic driving conditions, such as cornering or evasive maneuvers, the output of the electric motors can be used to adjust the driving and braking forces of each axle, thereby achieving load transfer and optimizing the vehicle's handling and stability.

[0087] The above-mentioned trailer axle load control method has the following advantages:

[0088] 1. Improve traction efficiency: Reasonable load distribution can reduce the rolling resistance of the vehicle during driving, reduce energy consumption, and thus improve fuel efficiency. Ensure that the drive wheels have sufficient traction, especially on slippery roads or when starting or climbing, to reduce slipping and power loss.

[0089] 2. Improve safety: By optimizing load distribution, accidents such as rollover and skidding caused by uneven load can be reduced, thus improving driving safety. Reasonable load distribution helps improve braking efficiency, reduce braking distance, and reduce risks during emergency braking.

[0090] 3. Extend vehicle life: Reasonable load distribution can reduce uneven wear of the suspension system and tires, extend their service life and reduce maintenance costs. Since damage caused by uneven load is reduced, the frequency and cost of vehicle maintenance will be reduced.

[0091] 4. Improve cargo loading efficiency: The intelligent load distribution system can optimize the load distribution according to the weight and volume of the cargo, improve the load utilization of the trailer, and by precisely controlling the load distribution, it can reduce the time spent on adjusting the load and speed up loading and unloading.

[0092] 5. Improve driving comfort: Reasonable load distribution can reduce vehicle bumps on uneven roads, improve driving comfort and reduce driver fatigue.

[0093] Optionally, the trailer control system has four operating modes to improve the maneuverability of the tractor and trailer and provide additional braking force when necessary. The following is a detailed explanation of the four modes:

[0094] 1. Trailer energy recovery mode:

[0095] Purpose: To recover energy during braking and improve energy efficiency.

[0096] Working principle: When the tractor and trailer slow down or brake, the auxiliary drive motor on the trailer can work as a generator, converting kinetic energy into electrical energy and storing it back in the power battery.

[0097] Advantages: Reduce energy loss during braking, extend battery life, reduce thermal load on the braking system, and improve braking efficiency.

[0098] 2. Trailer auxiliary driving mode:

[0099] Purpose: To provide additional traction, especially when starting, climbing a slope or with a heavy load.

[0100] How it works: The auxiliary drive motor on the trailer provides additional power when needed to help the tractor push the trailer together.

[0101] Advantages: Improve vehicle acceleration performance, reduce the burden on the tractor engine, improve gradeability, and reduce fuel consumption.

[0102] 3. Trailer differential steering mode:

[0103] Purpose: To improve the maneuverability and stability of the trailer when turning.

[0104] Working principle: When turning, the inner and outer wheels of the trailer rotate at different speeds to reduce tire wear and improve turning flexibility. The auxiliary drive motor on the trailer can control the speed of different wheels to achieve differential steering.

[0105] Advantages: Reduce turning radius, improve vehicle maneuverability in narrow spaces, and reduce tire wear.

[0106] 4. Trailer hybrid braking mode:

[0107] Purpose: To provide additional braking force when needed, improving braking efficiency and safety.

[0108] Working principle: In combination with conventional pneumatic brake systems and electronically controlled brake systems (such as TEBS), the auxiliary drive motor can provide additional braking force in emergency braking or when additional braking force is required.

[0109] Advantages: Improve braking response speed, reduce braking distance, improve braking stability on slippery roads, and reduce brake system wear.

[0110] The combined effect of these four modes can significantly improve the maneuverability and safety of tractors and trailers: Improved efficiency: Through energy recovery and auxiliary drive, energy utilization efficiency is improved and operating costs are reduced. Enhanced maneuverability: The differential steering mode improves the vehicle's maneuverability, especially in complex road conditions and narrow spaces. Improved safety: The hybrid braking mode provides faster and more stable braking capabilities, reducing risks in emergency situations. Adaptability: These modes can automatically switch according to actual driving conditions and needs to ensure that the vehicle is always in the best working condition.
