[0002] With the development of new energy vehicle technology, electric tractors have been widely used in the field of logistics and transportation. In practical applications, in addition to basic driving functions, many electric tractors also need to be equipped with special upper equipment to complete specific operations. For example, a powder tanker needs to be equipped with a special upper motor to perform operations such as soot blowing.

[0003] In the current technical solution, tractors usually use an independent drive motor controller to control the vehicle's driving, and also need to be equipped with a dedicated upper motor controller to control the operation of the upper motor. This design requires the entire vehicle to be equipped with two completely independent motor control systems. The upper motor controller needs to accurately control the motor's speed and output power according to the operation requirements to ensure the quality of the operation.

[0004] However, this dual-controller technology has obvious shortcomings: first, the addition of an independent upper motor controller will significantly increase the cost of the vehicle; second, the additional controller will occupy the limited space of the vehicle, which will cause inconvenience to the layout of the vehicle; third, the maintenance and management of the two control systems will also increase the cost of use. These problems are becoming increasingly prominent in practical applications, and a more optimized technical solution is urgently needed.

[0054] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. In the description of the present invention, it should be noted that the term "or" is usually used in the sense of including "and / or", unless the content clearly indicates otherwise.

[0055] In the description of the present application, the terms “first”, “second”, etc. are only used to distinguish the descriptions and should not be understood as indicating or implying relative importance.

[0056] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] At present, commercial vehicles (such as tractors) usually use independent drive controllers and bodywork controllers to control the drive motor and bodywork motor respectively. This solution not only increases the hardware cost of the vehicle control system, but also complicates the system architecture.

[0058] In order to solve various problems existing in the prior art, an embodiment of the present invention provides a power controller multiplexing control device, which is preferably suitable for purely electrically driven commercial vehicles, such as electric trucks, electric buses, electric transport vehicles, electric tractors, etc. The embodiment of the present invention is preferably suitable for electric tractors, which are provided with a drive system and a superstructure system; wherein the drive motor drives the wheels to rotate through transmission mechanisms such as a transmission, a drive shaft and axles to provide driving power for the tractor; the superstructure motor 140 is used to drive the lifting mechanism of the tractor, which includes hydraulic system components such as a hydraulic pump and a cylinder, and is used to convert the torque output electricity of the DC motor into hydraulic power, thereby realizing mechanical operation.

[0059] In this embodiment, the specific specifications, models and structures of the drive motor 130, the transmission mechanism, the upper motor 140 and the lifting mechanism are no longer limited, and those skilled in the art can make adaptive selections or adjustments as needed.

[0060] like Figure 1In one embodiment of the present invention, the power controller multiplexing control device includes a power battery 110, a power controller 120, a drive motor 130, a mounted motor 140, a first relay 150, a second relay 160, a power distribution unit 170 and a vehicle controller 180; wherein the power controller 120 is electrically connected to the drive motor 130 and the mounted motor 140 respectively, the first relay 150 is arranged on the connection line between the power controller 120 and the drive motor 130, the second relay 160 is arranged on the connection line between the power controller 120 and the mounted motor 140, the first relay 150 and the second relay 160 are both electrically connected to the power distribution unit 170, and the vehicle controller 180 is communicatively connected to the power controller 120 and the power distribution unit 170 respectively.

[0061] Specifically, the power battery 110 serves as the energy source of the entire power controller multiplexing control device, providing the required electric energy for the drive motor 130 and the upper motor 140; the drive motor 130 is installed in the power transmission system of the vehicle to provide the vehicle with driving power; the upper motor 140 is used to drive the hydraulic pump, thereby realizing mechanical operations such as lifting; the first relay 150 and the second relay 160 are circuit switch elements, which can determine the output path of the electric energy through on-off control to ensure that only one motor is connected to the power battery 110 at any time; the power distribution unit 170 is responsible for executing the on-off control of the relay, receiving the control instruction and outputting the corresponding control signal to the relay, thereby realizing the switching of the power supply path. In this device, the above-mentioned structures are interconnected through electrical lines or communication lines to form a complete control device. Those skilled in the art should understand that in this embodiment, the electrical connection is mainly used for the transmission of electric energy, while the communication connection is used for the transmission of control signals and status information.

[0062] In one embodiment of the present invention, the power controller 120 is integrated with a drive control module and a body control module, the drive control module is used to control the operation of the drive motor 130, and the body control module is used to control the operation of the body motor 140. The first relay 150 and the second relay 160 can be turned on or off, and the power controller 120 can also call the drive control module or the body control module accordingly according to the vehicle operation state.

[0063] In one embodiment of the present invention, the power controller 120 realizes the function of multiplexing one controller to control two motors with different characteristics by integrating a drive control module and a superstructure control module; the above-mentioned drive control module and superstructure control module are not independent hardware modules, but two control programs integrated in the power controller 120. These two control programs respectively contain their own required control algorithms and parameter configurations, and can be switched and called according to control mode instructions to realize the control function of one controller hardware for two motors with different characteristics, thereby avoiding the hardware redundancy of using two sets of independent controllers.

[0064] In one embodiment of the present invention, the drive control module includes the control algorithm and parameter configuration required for the drive motor 130, and can achieve precise control of the drive motor 130 according to vehicle speed, torque and other requirements; the upper body control module includes the control algorithm and parameter configuration required for the upper body motor 140, and can adjust the speed, current, etc. of the upper body motor 140 according to operating requirements.

[0065] Specifically, when the vehicle is in a driving state, the power controller 120 calls the drive control module, at which time the first relay 150 is closed and the second relay 160 is disconnected, and the electric energy of the power battery 110 is supplied to the drive motor 130 through the first relay 150. The drive control module calculates the required motor torque according to information such as the accelerator pedal position and vehicle speed, and outputs a control signal through a corresponding control strategy to ensure that the drive motor 130 runs smoothly.

[0066] When the vehicle needs to perform a lifting operation, the power controller 120 switches to the upper body control module, and at the same time the first relay 150 is disconnected and the second relay 160 is closed, and the power of the power battery 110 is supplied to the upper body motor 140 through the second relay 160. The upper body control module controls the speed and output torque of the upper body motor 140 according to the operation instruction to ensure that the hydraulic system can work stably.

[0067] During the module switching process, the power controller 120 will first ensure that the currently working motor stops running completely, and then allow another control module to take over the work. This control strategy can effectively avoid the impact during the switching process and improve the reliability and safety of the system.

[0068] In one embodiment of the present invention, the power controller 120 is essentially a motor controller, and its structure includes a power conversion unit, a drive circuit, a sampling circuit and a control chip; wherein the control chip is the control core of the entire motor controller, and has a built-in control algorithm of a drive control module and an upper control module, and can output corresponding control signals to the power conversion unit according to corresponding instructions, and the power conversion unit can perform corresponding electric energy conversion according to different control modes. In this embodiment, the specific model or specification of the power controller 120 is no longer specifically limited, and those skilled in the art can make corresponding choices according to actual needs.

[0069] In one embodiment of the present invention, the vehicle controller 180, as the central control unit of the vehicle, can obtain the vehicle operating status and send the vehicle operating status and control mode instructions to the power controller 120. The control mode instructions are used to instruct the power controller 120 to call the drive control module or the upper body control module; the vehicle controller 180 can also send relay control instructions to the distribution unit 170 according to the vehicle operating status to control the on and off states of the first relay 150 and the second relay 160 to ensure that only one of the first relay 150 and the second relay 160 can be turned on at the same time.

[0070] Specifically, the vehicle controller 180 can obtain various types of vehicle operating status information in real time, including vehicle speed, gear position, accelerator pedal position, brake pedal position, lifting operation switch status, power battery 110 status, driving motor 130 and upper motor 140 working status information, etc. Then, based on the acquired operating status information, the vehicle controller 180 determines the working mode that the current vehicle needs to enter. For example, when it is detected that the vehicle needs to drive (such as the gear is in D gear and the accelerator pedal is pressed), it is determined to enter the driving mode; when it is detected that a lifting operation is required (such as the vehicle is stopped and the lifting switch is activated), it is determined to enter the operation mode.

[0071] In one embodiment of the present invention, when it is necessary to enter the driving mode, the vehicle controller 180 needs to first confirm that the upper motor 140 has stopped working, and then send a control instruction to the distribution unit 170 to disconnect the second relay 160. After waiting for confirmation that the second relay 160 is completely disconnected, it sends a control instruction to the distribution unit 170 to close the first relay 150. After waiting for the first relay 150 to close the confirmation signal, the drive motor 130 is allowed to work.

[0072] In one embodiment of the present invention, when it is necessary to enter the operation mode, the vehicle controller 180 first confirms that the drive motor 130 has stopped working, and then sends a control instruction to the distribution unit 170 to disconnect the first relay 150. After waiting for confirmation that the first relay 150 is completely disconnected, a control instruction is sent to the distribution unit 170 to close the second relay 160. After the second relay 160 receives a closing confirmation signal, the upper motor 140 is allowed to work.

[0073] In one embodiment of the present invention, the vehicle controller 180 also needs to ensure the safety of system operation. Preferably, when in the process of mode switching, the vehicle controller 180 needs to ensure that one mode is completely exited before allowing another mode to start. At the same time, it is also necessary to monitor the status of the relay in real time to prevent the two relays from closing at the same time. If an abnormal condition (such as relay adhesion, etc.) is detected, an emergency (forced) disconnection instruction is immediately sent to the power distribution unit 170.

[0074] In one embodiment of the present invention, the distribution unit 170 serves as a power distribution and control module in the system, and is mainly composed of a relay drive circuit, a status detection circuit, a control chip, and a protection circuit. The distribution unit 170 can receive relay control instructions sent by the vehicle controller 180, and execute on-off control of the two relays, and can also feed back the actual status of the relay to the vehicle controller 180.

[0075] Based on the above-mentioned power controller multiplexing control device, in one embodiment of the present invention, a power controller multiplexing control method is also provided, such as Figure 2 , the method comprises the following steps:

[0076] Step S210, obtaining the vehicle operating status.

[0077] In one embodiment of the present invention, the vehicle operating state includes at least vehicle speed information and operating mode requirement information, and the operating mode requirement information is used to indicate the vehicle travel requirement or the loading operation requirement.

[0078] In one embodiment of the present invention, in addition to the vehicle speed information, the vehicle operating status also includes gear information, accelerator pedal position information, brake pedal position information, lifting operation switch status information, voltage, current and SOC information of the power battery 110, and working status information of the drive motor 130 and the upper motor 140.

[0079] In one embodiment of the present invention, the operating mode requirement information can be determined by the above-mentioned vehicle operating status. For example, the vehicle's travel requirements can be determined based on at least the gear information and the accelerator pedal position information, and the upper installation operation requirements can be determined based on at least the vehicle speed information and the lifting operation switch status.

[0080] Step S220, determining the operating mode according to the vehicle operating state.

[0081] In one embodiment of the present invention, when the operating mode requirement information indicates the vehicle's travel requirement, such as when it is detected that the gear position is in D gear and the driver presses the accelerator pedal, the operating mode is determined to be the driving mode; when the operating mode requirement information indicates the upper loading operation requirement, and the vehicle speed information indicates that the vehicle speed is zero, such as when the driver activates the lifting operation switch when the vehicle is completely stopped, the operating mode is determined to be the operation mode.

[0082] In one embodiment of the present invention, in order to ensure operation safety, before switching the operation mode to the driving mode, it is necessary to detect the operating status of the upper motor 140. When it is detected that the upper motor 140 is in a stopped state, the operation mode is switched. When it is detected that the upper motor 140 is in a running state, a prompt message is output and the operation mode is maintained.

[0083] In one embodiment of the present invention, before switching from driving mode to operation mode, the vehicle speed information is first detected, and the switch is allowed only when the vehicle is completely stationary. If the upper installation operation demand is detected when the vehicle speed is not zero, the vehicle controller 180 will keep the current operation mode unchanged and output a prompt message until the vehicle stops completely to prevent the vehicle from mistakenly starting the upper installation operation function during driving. Step S230, generate a relay control instruction and a control mode instruction based on the operation mode.

[0084] In one embodiment of the present invention, when the operation mode is the driving mode, a relay control instruction for controlling the first relay 150 to be closed and the second relay 160 to be opened, and a control mode instruction for calling the drive control module are generated.

[0085] Specifically, when entering the driving mode, the vehicle controller 180 first generates a relay control instruction to control the second relay 160 to disconnect, and after confirming that the second relay 160 is completely disconnected, controls the first relay 150 to close, thereby switching the power energy of the power battery 110 to the drive motor 130 circuit, and at the same time generates a control mode instruction to call the drive control module to take over the control of the drive motor 130.

[0086] In one embodiment of the present invention, when the operation mode is the working mode, a relay control instruction for controlling the first relay 150 to be opened and the second relay 160 to be closed, and a control mode instruction for calling the upper control module are generated.

[0087] Specifically, when entering the operation mode, the vehicle controller 180 generates an opposite relay control instruction, that is, first controls the first relay 150 to disconnect, and then controls the second relay 160 to close after confirming the disconnection, switches the power energy of the power battery 110 to the upper motor 140 circuit, and generates a control mode instruction to call the upper control module to take over the control of the upper motor 140.

[0088] In one embodiment of the present invention, during the switching process between the two modes, the vehicle controller 180 will strictly execute the relay switching timing to ensure that there is sufficient disconnection dead time between the two relays to avoid the risk of short circuit. Through the control instruction generation mechanism based on the operating mode of this embodiment, the safe switching of the power battery 110 and the correct allocation of control authority can be guaranteed.

[0089] Step S240, sending a relay control instruction to the power distribution unit to control the on / off state of the first relay and the second relay.

[0090] In one embodiment of the present invention, when the distribution unit 170 receives a relay control instruction, it can perform on-off control of the relay through the relay driving circuit. During the control process, the distribution unit 170 will detect the actual working status of the relay in real time and feed back the status information to the vehicle controller 180 to ensure the reliability of relay switching.

[0091] Step S250, sending a control mode instruction to the power controller to call the drive control module or the upper body control module.

[0092] In one embodiment of the present invention, the power controller 120 activates the corresponding control module according to the received control mode instruction.

[0093] Specifically, in the driving mode, when the drive control module is called, it starts to receive signals from the accelerator pedal, brake pedal, etc., and performs closed-loop control on the speed and torque of the drive motor 130 according to these signals to achieve smooth driving of the vehicle.

[0094] Specifically, in the operation mode, when the upper body control module is called, it starts to respond to control signals such as the lifting operation switch, controls the upper body motor 140 to perform lifting, lowering and other actions, and monitors parameters such as motor speed and lifting height in real time to ensure that the operation process is safe and reliable.

[0095] like Figure 3 and Figure 4 In one embodiment of the present invention, a power controller multiplexing control method is also provided, the method comprising the following steps:

[0096] Step S310 , when it is determined that the vehicle needs to move at this time, the vehicle controller 180 sends a command to the power distribution unit 170 to disconnect the second relay 160 and close the first relay 150 .

[0097] In step S320, the vehicle controller 180 sends code 1 to the power controller 120, which means that the power controller 120 runs the program in the drive control module at this time. The power controller 120 responds to the instruction and the vehicle moves.

[0098] Step S330, when the vehicle needs to run the upper motor 140 at this time, the vehicle controller 180 needs to determine whether the vehicle speed is zero at this time. If it is not zero, the upper motor 140 is not allowed to run; when the vehicle speed is zero, the vehicle controller 180 sends an instruction to the power distribution unit 170 to disconnect the first relay 150 and close the second relay 160.

[0099] In step S340 , the vehicle controller 180 sends code 0 to the power controller 120 , indicating that the power controller 120 is running the program in the upper control module. At this time, the power controller 120 controls the upper motor 140 to run at the rated speed of the upper motor 140 .

[0100] In one embodiment of the present invention, a vehicle is further provided. The vehicle is equipped with the above-mentioned power controller multiplexing control device and is capable of executing the above-mentioned power controller multiplexing control method.
