[0002] In traditional fuel-powered tractors, all power is distributed to the tractor unit, with no power allocated to the trailer. In the era of new energy vehicles, power is distributed between the tractor and trailer based on their loads. Current technologies include schemes that distribute power between the tractor engine and trailer motor based on the trailer's driving status and battery status. However, this approach distributes power to the trailer under certain operating conditions based on the power system configuration, and in some scenarios, it cannot guarantee optimal overall vehicle performance.

[0024] Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0025] Figure 1 A schematic diagram of the power distribution process of a traction train according to an embodiment of this application is shown, the method including the following steps:

[0026] S100: Obtain the load distribution of the tractor train and determine the power distribution parameters of the tractor and trailer based on the load distribution.

[0027] Specifically, the load distribution of the tractor train is determined by the axle load of the tractor and the axle load of the trailer.

[0028] For example, the tractor has 1 axle on the front wheel and 2 axles on the rear wheel; the trailer has 3 axles on the rear wheel. The load distribution of the tractor train can be determined based on the load distribution of the tractor and the trailer, and then the power distribution parameters of the tractor and the trailer can be determined based on the load distribution.

[0029] Power distribution parameters refer to the distribution of the total driving force of the tractor train to the tractor and trailer in a certain proportion.

[0030] A reasonable ratio can effectively reduce the power of the tractor and improve the overall vehicle's power performance.

[0031] S200 constructs a dynamic model of the traction train based on the power distribution parameters, and performs simulations on multiple preset working conditions based on the dynamic model to determine the power system parameters of the traction train. The power system parameters are used to define the drive distribution method between the tractor and the trailer.

[0032] Specifically, the dynamic model is a simulation model based on the power drive system of the traction train. The dynamic model can provide a reference for the configuration of the power system of the traction train. Specifically, the dynamic model is used to simulate the operating conditions of the traction train and further improve the determination of the parameters of the power system of the traction train.

[0033] In practical applications, this enables the traction train to be used in multiple operating conditions and to implement power distribution between the tractor and the trailer.

[0034] The dynamic system mainly uses dynamic theory to simulate the traction train, thereby obtaining the method of power distribution according to the driving force, and distributing the power to the tractor and trailer in a certain proportion.

[0035] The dynamics theory involved mainly concerns the relationship between driving force and tire adhesion. The driving force Ft is ultimately applied to the tire through the adhesion force Fψ from the ground. The adhesion force Fψ is proportional to the normal force P acting on the tire and the adhesion coefficient μ. Under specific load and road conditions, the adhesion force that the tire can obtain is definite, existing in the following two states:

[0036] (1) Ft≤Fψ, that is, the driving force output by the power system is less than or equal to the adhesion force. In this case, the actual driving force of the car is equal to Ft.

[0037] (2) Ft>Fψ, that is, the driving force output by the power system exceeds the adhesion of the tire, and the tire will slip. In this case, the actual driving force of the car is less than or equal to Fψ.

[0038] Based on the above theory, distributed drive can achieve greater tire adhesion, especially on low-adhesion surfaces, where its advantages are more pronounced. Under full load conditions, the load of the tractor and trailer is used to select the power system parameters of the tractor and motor, allowing the entire vehicle to obtain maximum adhesion and improve the dynamics of the tractor train.

[0039] The S300 distributes the driving force between the tractor and trailer according to the power system parameters and drive distribution method.

[0040] The driving force of the tractor and trailer is distributed according to the power system parameters and drive distribution method.

[0041] In this embodiment, the power distribution parameters of the tractor and trailer are determined by the load distribution of the tractor train. Then, a dynamic model of the tractor train is constructed based on the power distribution parameters. Simulations are performed on multiple preset working conditions based on the dynamic model, so that the tractor train can allocate power proportionally and distribute power to the whole vehicle under each preset working condition in the simulation. In addition, the power system parameters of the tractor train are selected through the dynamic model, making the application scenarios of the tractor train more diverse.

[0042] Furthermore, in S100, the load distribution of the tractor train is acquired, and the power distribution parameters between the tractor and trailer are determined based on the load distribution, including:

[0043] S110, Based on the axle number allocation of the tractor and trailer, determine the load distribution of the tractor and trailer that make up the tractor train;

[0044] S120, determines the power distribution parameters of the tractor and trailer based on the load distribution of the tractor and trailer.

[0045] Specifically, based on the axle number distribution of the wheel sets of the tractor and trailer, the load distribution of the tractor and trailer is determined, and the power distribution parameters of the tractor and trailer are further determined.

[0046] Optionally, the power system parameters of the tractor and trailer can be set separately according to the power distribution parameters. As an optional implementation method, the power systems of the tractor and trailer are set separately, and the power systems of the tractor and trailer are used as the power systems of the whole vehicle. The driving force required by the whole vehicle is calculated based on the power system of the whole vehicle, and then the driving force required by the whole vehicle is distributed according to the power distribution parameters.

[0047] In this embodiment, the power distribution parameters of the tractor and trailer are determined by the load distribution of the tractor and trailer, thereby enabling a better determination of the power system parameters of the tractor train.

[0048] Furthermore, S200 constructs a dynamic model of the traction train based on the power distribution parameters, including:

[0049] S210, based on the driving range requirements of the tractor train, determines the battery parameters of the entire vehicle, including the battery parameters of the tractor and the trailer.

[0050] S220 determines the vehicle motor parameters based on the matching relationship with the vehicle battery parameters. The vehicle motor parameters include the motor parameters of the tractor and the motor parameters of the trailer.

[0051] S230 uses the vehicle battery parameters and vehicle motor parameters to construct a dynamic model of the traction train.

[0052] Specifically, the battery parameters of the entire vehicle are determined based on the driving range requirements of the traction train, so that the battery capacity is adapted to the driving range requirements.

[0053] The combined battery capacity of the tractor and trailer must match the total battery requirement. Additionally, the tractor's battery must be compatible with its motor, and the trailer's battery with its motor.

[0054] Based on the matching relationship of the vehicle battery parameters, the vehicle battery parameters and vehicle motor parameters are determined, and a dynamic model of the traction train is further constructed.

[0055] In this embodiment, a dynamic model of the traction train is established using simulation software. Based on specific operating conditions, the maximum adhesion force obtained by the entire vehicle is calculated to improve the vehicle's dynamic performance.

[0056] Furthermore, the dynamic model is simulated based on multiple set operating conditions to determine the distributed drive strategy of the traction train;

[0057] Based on the distributed drive strategy, the power system parameters of the traction train are determined.

[0058] Furthermore, the S300 distributes the driving force between the tractor and trailer based on powertrain parameters and drive distribution methods, including:

[0059] S310: Obtain the power system status of the traction train and determine the corresponding vehicle operating conditions based on the power system status.

[0060] The S320 distributes driving force to the tractor and trailer based on power system parameters and drive distribution method.

[0061] Specifically, the power system status includes vehicle speed, vehicle power demand, operating status, and the angle between the tractor and trailer.

[0062] The vehicle's operating conditions are determined based on the power system status, and driving force is distributed to the tractor and trailer according to the power system parameters and drive distribution method.

[0063] Power distribution includes adaptively distributing the power required by the vehicle to the power systems of the tractor and trailer.

[0064] In this embodiment, when distributing power, the tractor's power system is made to operate at optimal power, and the other operating power of the vehicle is distributed to allow the trailer's power system to output power, thereby improving the overall vehicle's power performance.

[0065] Furthermore, S310 acquires the power system status of the traction train and determines the corresponding vehicle operating conditions based on the power system status, including:

[0066] S311, the power system status of the traction train includes the remaining power of the power battery, the status of the motor, and the angle between the tractor and the trailer;

[0067] S312, based on the priority order of each power system status, adjusts the driving force distribution method of the tractor and trailer in real time according to the power system status.

[0068] Specifically, as an optional implementation, the power system status of the traction train includes the remaining power of the power battery, the status of the motor, and the angle between the tractor and the trailer.

[0069] The vehicle operating conditions are determined based on the priority order of the power system states and the corresponding power system states.

[0070] Priority can be ordered based on the urgency of each power system state. For example, if the angle between the tractor and trailer indicates that the tractor train is turning, then the drive force distribution method between the tractor and trailer can be adjusted based on the turning state.

[0071] In this embodiment, the driving force can be adjusted according to the priority order of the power system states of the traction train, so as to obtain better overall vehicle power, economy and off-road performance.

[0072] Furthermore, following S300, the method also includes:

[0073] S400 determines the braking force distribution method between the tractor and the trailer based on the load distribution of the tractor train.

[0074] S420 adjusts the driving force of the tractor and semi-trailer based on the braking force distribution method during the operation of the tractor train.

[0075] Based on the braking force distribution parameters, the braking force of the tractor and semi-trailer is calculated, and the tractor and semi-trailer are controlled according to the braking force.

[0076] As an alternative implementation, the energy recovered from the electric drive axles of the tractor and trailer is used for electric braking, with mechanical power supplementing any insufficient braking force.

[0077] The vertical load distribution of each axle on the supporting plane is represented by the ratio of the sum of the axle loads of the tractor to the sum of the axle loads of the trailer.

[0078] The sum of the axle loads of the tractor and the trailer is determined based on the mass limits of each axle.

[0079] In this embodiment, the braking pressure of the tractor and the braking pressure of the trailer are determined by the braking force distribution method of the tractor, and the driving force distribution of the tractor and the trailer is adjusted to alleviate the situation of the train folding during braking.
