Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle control technology, and in particular to a power controller multiplexing control device, method, electronic device, and storage medium. Background Technology
[0002] With the development of new energy vehicle technology, electric tractor units have been widely used in the logistics and transportation sector. In practical applications, many electric tractor units, in addition to their basic driving functions, also require specialized superstructure equipment to complete specific tasks. For example, powder tank trucks require a dedicated superstructure motor for tasks such as ash blowing.
[0003] In current technical solutions, tractor units typically use an independent drive motor controller to control vehicle movement, and also require a separate dedicated superstructure motor controller to control the operation of the superstructure motor. This design necessitates two completely independent motor control systems for the entire vehicle. The superstructure motor controller needs to precisely control the motor speed and output power according to operational requirements to ensure operational quality.
[0004] However, this dual-controller solution has significant drawbacks: First, adding a separate upper-body motor controller significantly increases the overall vehicle cost; second, the additional controller occupies limited vehicle space, causing inconvenience in vehicle layout; and third, the maintenance and management of two control systems also increase operating costs. These problems are becoming increasingly prominent in practical applications, necessitating a more optimized technical solution.
[0005] Therefore, how to simplify the control system architecture and reduce costs and save space while ensuring the normal operation of various functions is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0025] In one possible implementation, the vehicle operating status includes vehicle speed information and operating mode requirement information, which is used to indicate the vehicle's travel requirements or the requirements for the superstructure operation.
[0026] In one possible implementation, the operating mode is determined based on the vehicle's operating status, including:
[0027] When the operating mode demand information indicates the vehicle's travel demand, the operating mode is determined to be the driving mode;
[0028] When the operating mode requirement information indicates the upper body operation requirement and the vehicle speed information indicates that the vehicle speed is zero, the operating mode is determined to be the operation mode.
[0029] In one possible implementation, relay control instructions and control mode instructions are generated based on the operating mode, including:
[0030] When the operating mode is driving mode, a relay control command is generated to control the first relay to close and the second relay to open, as well as a control mode command to call the drive control module.
[0031] When the operating mode is the work mode, a relay control command is generated to control the first relay to open and the second relay to close, as well as a control mode command to call the upper-mounted control module.

By integrating a drive control module and a superstructure control module into the power controller, it achieves the function of multiplexing control of both the drive motor and the superstructure motor with a single controller. Through the control of the first and second relays by the power distribution unit, the drive motor and the superstructure motor are prevented from being connected to the power controller simultaneously, avoiding power distribution issues. The vehicle controller dynamically selects the operating mode based on the vehicle's operating status and coordinates the on / off states of the control relays and the switching of control modules, achieving seamless switching between drive control and superstructure control. Specifically, during mode switching, the system also detects the operating status of the superstructure motor and makes a safety judgment.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. In the description of this invention, it should be noted that the term "or" is generally used to include the meaning of "and / or," unless otherwise expressly indicated.
[0055] In the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0056] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0057] Currently, commercial vehicles (such as tractor units) typically use separate drive controllers and superstructure controllers to control the drive motor and superstructure motor respectively. This approach not only increases the hardware cost of the vehicle control system but also complicates the system architecture.
[0058] To address the various problems existing in the prior art, embodiments of the present invention provide a power controller multiplexing control device. This device is preferably applicable to purely electric commercial vehicles, such as electric trucks, electric buses, electric transport vehicles, and electric tractors. Embodiments of the present invention are preferably applicable to electric tractors, which are equipped with a drive system and a superstructure system. The drive motor drives the wheels to rotate through transmission mechanisms such as a gearbox, drive shaft, and axle, providing driving power for the tractor. The superstructure motor 140 is used to drive the lifting mechanism of the tractor. This mechanism includes hydraulic system components such as a hydraulic pump and cylinders, which are used to convert the torque output power 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, transmission mechanism, superstructure motor 140 and lifting mechanism are no longer limited. 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 superstructure 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 superstructure motor 140 respectively, the first relay 150 is disposed on the connection line between the power controller 120 and the drive motor 130, the second relay 160 is disposed on the connection line between the power controller 120 and the superstructure motor 140, both the first relay 150 and the second relay 160 are 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 for the entire power controller multiplexing control device, providing the necessary electrical energy to the drive motor 130 and the superstructure motor 140. The drive motor 130 is installed in the vehicle's power transmission system to provide driving power for the vehicle. The superstructure motor 140 drives the hydraulic pump, thereby enabling mechanical operations such as lifting. The first relay 150 and the second relay 160, as circuit switching elements, can determine the output path of electrical energy through on / off control, ensuring that only one motor is connected to the power battery 110 at any given time. The power distribution unit 170 is responsible for executing the on / off control of the relays, receiving control commands, and outputting corresponding control signals to the relays, thereby achieving the switching of the power supply path. In this device, the above-mentioned structures are interconnected through electrical 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 electrical 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 integrates a drive control module and a superstructure control module. The drive control module controls the operation of the drive motor 130, and the superstructure control module controls the operation of the superstructure motor 140. The first relay 150 and the second relay 160 can be selectively activated. The power controller 120 can also call the drive control module or the superstructure control module according to the vehicle's operating status.
[0063] In one embodiment of the present invention, the power controller 120 integrates a drive control module and an upper-mount control module to realize the function of multiplexing control of two motors with different characteristics by one controller. The drive control module and the upper-mount control module are not independent hardware modules, but two control programs integrated inside the power controller 120. These two control programs contain their respective control algorithms and parameter configurations, and can be switched and called according to control mode instructions to realize the control function of two motors with different characteristics by one controller hardware, thus avoiding hardware redundancy of using two 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, which can achieve precise control of the drive motor 130 according to the requirements of vehicle speed, torque and other factors; the superstructure control module includes the control algorithm and parameter configuration required for the superstructure motor 140, which can adjust the speed, current and other parameters of the superstructure motor 140 according to the operation requirements.
[0065] Specifically, when the vehicle is in motion, the power controller 120 calls the drive control module. At this time, the first relay 150 is closed and the second relay 160 is open, and the power battery 110 supplies electrical energy to the drive motor 130 through the first relay 150. The drive control module calculates the required motor torque based on information such as the accelerator pedal position and vehicle speed, and outputs control signals through corresponding control strategies to ensure the smooth operation of the drive motor 130.
[0066] When the vehicle needs to be lifted, the power controller 120 switches to the superstructure control module. At the same time, the first relay 150 is disconnected and the second relay 160 is closed, and the power battery 110 supplies electrical energy to the superstructure motor 140 through the second relay 160. The superstructure control module controls the speed and output torque of the superstructure motor 140 according to the work instructions to ensure that the hydraulic system can work stably.
[0067] During module switching, the power controller 120 first ensures that the currently operating motor completely stops running before allowing another control module to take over. 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, whose structure includes a power conversion unit, a drive circuit, a sampling circuit, and a control chip. The control chip is the core of the entire motor controller, incorporating a built-in drive control module and a control algorithm for the upper-level control module. It can output corresponding control signals to the power conversion unit according to corresponding instructions. The power conversion unit can then perform corresponding energy conversion based on different control modes. In this embodiment, the specific model or specifications of the power controller 120 are not specifically limited; those skilled in the art can make appropriate selections based on actual needs.
[0069] In one embodiment of the present invention, the vehicle controller 180, as the central control unit of the vehicle, is able to acquire the vehicle's operating status and send the vehicle's operating status and control mode command to the power controller 120. The control mode command is used to instruct the power controller 120 to call the drive control module or the superstructure control module. The vehicle controller 180 can also send relay control commands to the power distribution unit 170 according to the vehicle's operating status to control the on / off state of the first relay 150 and the second relay 160, ensuring 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 acquire various 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, and operating status information of drive motor 130 and superstructure motor 140. Then, based on the acquired operating status information, the vehicle controller 180 determines the operating mode that the vehicle needs to enter. For example, when it detects that the vehicle needs to drive (such as when the gear is in D and the accelerator pedal is depressed), it determines to enter the driving mode; when it detects that lifting operations need to be performed (such as when the vehicle is stopped and the lifting switch is activated), it determines 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 superstructure motor 140 has stopped working, and then send a control command to the power 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 command to the power distribution unit 170 to close the first relay 150. After waiting for the confirmation signal of the first relay 150 closing, the drive motor 130 is allowed to work.
[0072] In one embodiment of the present invention, when it is necessary to enter the working mode, the vehicle controller 180 first confirms that the drive motor 130 has stopped working, and then sends a control command to the power distribution unit 170 to disconnect the first relay 150. After waiting to confirm that the first relay 150 is completely disconnected, it sends a control command to the power distribution unit 170 to close the second relay 160. After the second relay 160 closes and a confirmation signal is received, the superstructure 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, and at the same time needs to monitor the status of the relays in real time to prevent two relays from closing at the same time. If an abnormal condition is detected (such as relay sticking), an emergency (forced) disconnection command is immediately sent to the power distribution unit 170.
[0074] In one embodiment of the present invention, the power distribution unit 170, as a power distribution and control module in the system, mainly consists of a relay drive circuit, a status detection circuit, a control chip, and a protection circuit. The power distribution unit 170 can receive relay control commands sent by the vehicle controller 180 and perform on / off control of two relays. It can also feed back the actual status of the relays to the vehicle controller 180.
[0075] Based on the aforementioned 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 includes the following steps:
[0076] Step S210: Obtain the vehicle's operating status.
[0077] In one embodiment of the present invention, the vehicle operating status includes at least vehicle speed information and operating mode requirement information, wherein the operating mode requirement information is used to indicate the vehicle's travel requirements or the requirements for the superstructure operation.
[0078] In one embodiment of the present invention, in addition to 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 operating status information of the drive motor 130 and the superstructure 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 travel requirement can be determined at least based on the gear information and accelerator pedal position information, and the superstructure operation requirement can be determined at least based on the vehicle speed information and the lifting operation switch status.
[0080] Step S220: Determine the operating mode based on the vehicle's operating status.
[0081] In one embodiment of the present invention, when the operating mode demand information indicates the vehicle's driving demand, if the gear is detected to be in D gear and the driver presses the accelerator pedal, the operating mode is determined to be the driving mode; when the operating mode demand information indicates the superstructure operation demand and the vehicle speed information indicates that the vehicle speed is zero, if the driver activates the lifting operation switch while 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 operational safety, the operating status of the superstructure motor 140 needs to be detected before switching the operation mode to the driving mode. When the superstructure motor 140 is detected to be in a stopped state, the operation mode is switched. When the superstructure motor 140 is detected to be 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 working mode, vehicle speed information is first detected. Switching is only allowed when the vehicle is completely stationary. If a superstructure work requirement is detected when the vehicle speed is not zero, the vehicle controller 180 will maintain the current operating mode and output a prompt message until the vehicle comes to a complete stop, to prevent the superstructure work function from being accidentally activated while the vehicle is in motion. Step S230: Generate relay control commands and control mode commands based on the operating mode.
[0084] In one embodiment of the present invention, when the operating mode is driving mode, a relay control command is generated to control the first relay 150 to close and the second relay 160 to open, as well as a control mode command to call the drive control module.
[0085] Specifically, when entering driving mode, the vehicle controller 180 first generates a relay control command to control the second relay 160 to disconnect. After confirming that the second relay 160 is completely disconnected, it controls the first relay 150 to close, thereby switching the power energy of the power battery 110 to the drive motor 130 circuit. At the same time, it generates a control mode command 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 operating mode is the work mode, a relay control command is generated to control the first relay 150 to open and the second relay 160 to close, and a control mode command is generated to call the upper-mounted control module.
[0087] Specifically, when entering the operating mode, the vehicle controller 180 generates the opposite relay control command, that is, first controls the first relay 150 to open, and after confirming the opening, controls the second relay 160 to close, switching the power battery 110 to the circuit of the superstructure motor 140, and generates a control mode command to call the superstructure control module, so that it takes over the control of the superstructure motor 140.
[0088] In one embodiment of the present invention, during the switching between the two modes, the vehicle controller 180 strictly executes the relay switching sequence to ensure that there is sufficient dead time between the two relays to avoid the risk of short circuit. Through this control command generation mechanism based on the operating mode in this embodiment, the safe switching of power battery 110 and the correct allocation of control authority can be guaranteed.
[0089] Step S240: Send a relay control command to the power distribution unit to control the on / off state of the first and second relays.
[0090] In one embodiment of the present invention, when the power distribution unit 170 receives a relay control command, it can perform relay on / off control through the relay drive circuit. During the control process, the power 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: Send a control mode command to the power controller to invoke the drive control module or the upper-mount 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 command.
[0093] Specifically, in driving mode, when the drive control module is invoked, it begins 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 based on these signals to achieve smooth vehicle driving.
[0094] Specifically, in the operation mode, when the superstructure control module is invoked, it begins to respond to control signals such as the lifting operation switch, controls the superstructure motor 140 to perform lifting and lowering actions, and monitors parameters such as motor speed and lifting height in real time to ensure the safety and reliability of the operation process.
[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] In step S310, when it is determined that the vehicle needs to move, 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, indicating that the power controller 120 is running the program in the drive control module. The power controller 120 responds to the command and the vehicle moves.
[0098] In step S330, when the vehicle needs to run the supermount motor 140, the vehicle controller 180 needs to determine whether the vehicle speed is zero. If it is not zero, the supermount motor 140 is not allowed to run. When the vehicle speed is zero, the vehicle controller 180 sends a command 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 body control module. At this time, the power controller 120 controls the upper body motor 140 to run at the rated speed of the upper body motor 140.
[0100] In one embodiment of the present invention, a vehicle is also provided, which is equipped with the above-described power controller multiplexing control device and is capable of executing the above-described power controller multiplexing control method. Preferably, the vehicle in this embodiment is a pure electric commercial vehicle, and more preferably an electric tractor.
[0101] This invention also provides an electronic device including a memory and a processor. The memory stores a computer program executed by the processor. When the computer program is executed by the processor, it causes the processor to perform the power controller multiplexing control method described above.
