[0029] In the following description, specific details such as specific system structures and technologies are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and circuits are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0030] As the core machinery for loading and transporting goods, loaders are widely used in various engineering fields, such as construction sites, earthwork operations, mines, etc. In order to control and troubleshoot the loaders, loaders are usually equipped with electronic control systems. The electronic control systems of related technologies are usually equipped with multiple different control units, such as MCU, TCU, VCU, Advanced Temperature System (ATS), etc., where MCU is used to control the body control system, engine control system, safety system, etc. in the loader, TCU is a shift controller used to control the shift components in the loader, VCU is used to manage the battery management system (BMS), motor control, energy recovery, charging management, etc., and ATS is used to control the air conditioning system in the loader, that is, each control unit controls the actions of different execution units respectively.

[0031] However, when an electronic control system is equipped with multiple control units, each control unit is only connected to the corresponding execution unit, resulting in surplus active ports on each control unit. This means that the control units in the electronic control system are not fully utilized, resulting in a waste of port resources. Furthermore, the control units need to be interconnected to enable information exchange. When multiple control units communicate using bus signals, network congestion may occur, resulting in partial signal loss, affecting the control reliability of the electronic control system. When multiple control units communicate using hard-wired signals (i.e., wiring harnesses), due to the harsh field environments and complex working conditions in some engineering fields, wiring harness failures (such as aging or damage) may cause signal interruption, affecting normal communication between the control units and causing malfunctions in the loader using the electronic control system. The greater the number of control units, the higher the probability of communication failure. Furthermore, when multiple control units communicate using wiring harnesses, the larger the number of harnesses, the higher the production cost. Furthermore, when a wiring harness fails, operators need to troubleshoot each harness individually, which is labor-intensive and difficult to troubleshoot.

[0032] To this end, the present application provides an electronic control system and a loader, wherein a domain controller module in the electronic control system is connected to multiple components (a handle assembly, a pedal assembly, and a motor assembly), so that the ports of the domain controller module are fully utilized, avoiding the problem of redundant effective ports of the control circuit, resulting in the control circuit not being fully utilized and wasting the port resources of the control circuit. At the same time, multiple components can be controlled by a single domain controller module, eliminating the need to set up additional control circuits or control chips, reducing the layout of the wiring harness and saving a certain amount of production costs.

[0033] The electronic control system and loader provided in this application are exemplarily introduced below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, an embodiment of the present application provides a loader 1, which includes a handle assembly 11, a pedal assembly 12 and a motor assembly 13. In order to realize information interaction and control of the handle assembly 11, the pedal assembly 12 and the motor assembly 13, the loader 1 provided by the present application also includes an electronic control system 14, which is connected to the handle assembly 11, the pedal assembly 12 and the motor assembly 13 respectively. The electronic control system 14 can obtain status information of the handle assembly 11 and the pedal assembly 12, and realize control of the motor assembly 13.

[0035] In one example, if Figure 2 As shown, the electronic control system 14 may include a domain controller module 141, which is respectively connected to the handle assembly 11, the pedal assembly 12 and the motor assembly 13. The domain controller module 141 is used to obtain the first state information of the handle assembly 11 and the second state information of the pedal assembly 12, and can control the action of the motor assembly 13 based on the first state information and / or the second state information.

[0036] Here, it is worth mentioning that the first state information is the state information generated in real time when the handle assembly 11 changes. When the user operates the handle assembly 11 (that is, the state of the handle assembly 11 changes), the domain controller module 141 can obtain the first state information corresponding to the handle assembly 11 at this time, and control the motor assembly 13 to move based on the first state information; the second state information is the state information generated in real time when the pedal assembly 12 changes. When the user steps on the pedal assembly 12 (that is, the state of the pedal assembly 12 changes), the domain controller module 141 can obtain the second state information corresponding to the pedal assembly 12 at this time, and control the motor assembly 13 to move based on the second state information.

[0037] In this example, the domain controller module 141 is connected to multiple components (i.e., the handle component 11, the pedal component 12, and the motor component 13), so that the ports of the domain controller module 141 are fully utilized, avoiding the problem that there are surplus valid ports of the domain controller module 141, resulting in the domain controller module 141 not being fully utilized, wasting the port resources of the domain controller module 141, and reducing the amount of code during software development. In addition, the domain controller module 141 can obtain the first state information of the handle component 11 and the second state information of the pedal component 12, and control the action of the motor component 13 based on the first state information and / or the second state information, that is, information interaction with the handle component 11 and the pedal component 12, as well as control of the motor component 13 can be achieved through a domain controller module 141. In this way, there is no need to set up additional control circuits or control chips, which reduces the layout of the wiring harness and saves a certain amount of production costs. Secondly, there is no need to set up additional control circuits or control chips, that is, there is no need for information interaction between multiple additional control circuits, which avoids the problem of network congestion and partial signal loss when multiple control circuits use bus signals to interact with each other, improves the reliability of signal transmission, and thus ensures the operational reliability of the electronic control system 14.

[0038] In one example, Figure 3 As shown, the handle assembly 11 includes at least a shift handle 111, a hydraulic handle 112, and a lifting handle 113. The shift handle 11 can be used to switch between forward and reverse gears. The hydraulic handle 112 can be used to move the bucket, boom, and other components. The lifting handle 113 can be used to raise and lower the bucket. The handle assembly 11 may also include other handles, and this application does not impose specific restrictions on this. The pedal assembly 12 includes at least a brake pedal 121 and an accelerator pedal 122. The brake pedal 121 can be used to decelerate and stop, and the accelerator pedal 122 can be used to accelerate and decelerate. The motor assembly 13 includes at least a shift motor 131, a hydraulic motor 132, and a travel motor 133. In this example, the shift handle 111, the hydraulic handle 112, the lifting handle 113, the brake pedal 121, the accelerator pedal 122, the shift motor 131, the hydraulic motor 132 and the travel motor 133 are respectively connected to the domain controller module 141. In this way, the domain controller module 141 in the electronic control system 14 provided in the present application is connected to multiple handles, pedals and motors, so that the ports of the domain controller module 141 are fully utilized, avoiding the problem of surplus effective ports of the domain controller module 141, resulting in the domain controller module 141 not being fully utilized and wasting the port resources of the domain controller module 141, and can reduce the amount of code during software development.

[0039] Here, it can be understood that the first status information of the above-mentioned handle assembly 11 may include the shift signal of the shift handle 111, the signal of the hydraulic handle 112 and the signal of the lifting handle 113, and the second status information of the pedal assembly 12 may include the stepping signal of the brake pedal 121 and the stepping signal of the accelerator pedal 122. The domain controller module 141 can receive status information from the shift handle 111, the hydraulic handle 112, the lifting handle 113, the brake pedal 121 and the accelerator pedal 122, and control the corresponding actions of the shift motor 131, the hydraulic motor 132 and the travel motor 133 based on these status information.

[0040] For example, when the operator switches the shift handle 111 to the neutral (N) gear, the shift handle 111 will send a shift signal indicating the neutral gear to the domain controller module 141. At this time, the travel motor 133 does not need to move, and the domain controller module 141 will not send instructions to the travel motor 133, and the loader 1 remains stationary.

[0041] When the operator switches the shift handle 111 to the forward (F) gear, the shift handle 111 sends a shift signal indicating the forward gear to the domain controller module 141. The domain controller module 141 controls the shift motor 131 to shift the gearbox of the shift motor 131 to the forward gear and sends a forward command to the travel motor 133, causing the loader 1 to begin moving forward. At this time, to ensure normal movement of the loader 1, the operator steps on the accelerator pedal 122, which sends a corresponding stepping signal to the domain controller module 141. The domain controller module 141 determines the throttle opening of the accelerator pedal 122 based on the stepping signal and adjusts the rotation speed of the travel motor 133 based on the throttle opening to change the travel speed of the loader 1.

[0042] When the operator switches the shift handle 111 to reverse (F) gear, the shift handle 111 sends a shift signal indicating reverse gear to the domain controller module 141. The domain controller module 141 then controls the shift motor 131 to shift the gearbox of the shift motor 131 to reverse gear and sends a reverse command to the travel motor 133, causing the loader 1 to begin reverse movement. At this point, to ensure normal movement of the loader 1, the operator steps on the accelerator pedal 122, which sends a corresponding stepping signal to the domain controller module 141. The domain controller module 141 determines the throttle opening of the accelerator pedal 122 based on the stepping signal and adjusts the rotation speed of the travel motor 133 based on the throttle opening to change the travel speed of the loader 1.

[0043] When the loader 1 is in neutral, forward gear or reverse gear, if the operator steps on the brake pedal 121 at this time, the brake pedal 121 will send a corresponding stepping signal to the domain controller module 141. The domain controller module 141 will clear the torque of the travel motor 133 based on the stepping signal, and at the same time control the hydraulic valve block to slow down or stop the loader 1 completely.

[0044] In summary, the domain controller module 141 can receive the shift signal from the shift handle 111, the pedal signal from the accelerator pedal 122, and the pedal signal from the brake pedal 121, and based on the shift signal, it can switch the gear of the shift motor 131 and send corresponding instructions to the travel motor 133 to change the action state of the loader 1. At the same time, it can also adjust the rotation speed and torque of the travel motor 133 based on the pedal signal from the accelerator pedal 122 and the pedal signal from the brake pedal 121, thereby accelerating or decelerating the loader 1. In this way, the action state and travel speed of the loader 1 can be controlled and adjusted by the domain controller module 141, that is, the domain controller module 141 can control multiple execution units simultaneously without the need for an additional control unit.

[0045] In this example, when the loader 1 is in neutral, forward gear, or reverse gear, if the working device of the loader 1 (such as a bucket, boom, and rocker arm, etc.) needs to be changed, the operator can do so by operating the hydraulic handle 112 and the lifting handle 113. For example, when the operator switches the hydraulic handle 112 to the lifting state, the hydraulic handle 112 sends a lifting signal to the domain controller module 141. The domain controller module 141 can control the action of the hydraulic motor 132 based on the lifting signal to lift the working device of the loader 1, wherein the domain controller module 141 can determine the opening of the hydraulic handle 112 based on the lifting signal to determine the rotation speed of the hydraulic motor 132, thereby determining the lifting speed of the working device. When the working device is lifted into place, the domain controller module 141 can also clear the torque of the hydraulic motor 132 so that the working device can remain in the lifted state.

[0046] When the operator switches the hydraulic handle 112 to the lowering state, the hydraulic handle 112 sends a lowering signal to the domain controller module 141. Based on the lowering signal, the domain controller module 141 controls the hydraulic motor 132 to move in the opposite direction, thereby lowering the working device of the loader 1. Based on the lowering signal, the domain controller module 141 determines the opening degree of the hydraulic handle 112 to determine the rotation speed of the hydraulic motor 132, thereby determining the lowering speed of the working device. When the working device is lowered into position, the domain controller module 141 also clears the torque of the hydraulic motor 132 to keep the working device in a low and flat position.

[0047] It is worth noting that the function of the lifting handle 113 is the same as the function and control logic of the hydraulic handle 112. Therefore, the lifting handle 113 can refer to the function and control logic of the hydraulic handle 112, which will not be described in detail. The loader 1 can be provided with only the hydraulic handle 112 or only the lifting handle 113, or both the hydraulic handle 112 and the lifting handle 113. The specific setting can be based on actual needs. For example, if the loader 1 is a small loader and the operating platform of the loader 1 is small, only the hydraulic handle 112 or the lifting handle 113 can be provided on the operating platform. When the loader 1 is a large loader, the operating platform of the loader 1 is large, and there may even be two operating platforms. In order to facilitate the operation of the operator, the hydraulic handle 112 and the lifting handle 113 need to be provided at different positions on the larger platform or on the two operating platforms, so as to facilitate the operation of the operator. This application does not impose specific restrictions on this.

[0048] In summary, the domain controller module 141 can receive lifting signals and lowering signals from the hydraulic handle 112 and / or the lifting handle 113, and control the action of the hydraulic motor 132 based on the lifting signals and lowering signals to change the action state of the working device of the loader 1 accordingly. At the same time, it can also adjust the rotation speed and torque of the hydraulic motor 132 based on the lifting signals and lowering signals, thereby adjusting the lifting and lowering speed of the working device accordingly.

[0049] In this way, the domain controller module 141 provided by the present application can control and adjust the overall action state and travel speed of the loader 1, the action state and lifting / lowering speed of the working device of the loader 1, that is, the domain controller module 141 provided by the present application integrates the functions of MCU, TCU and VCU, and can control multiple execution units at the same time, without the need to set up additional MCU, TCU and VCU, reducing the layout of the wiring harness and saving a certain amount of production cost. Secondly, there is no need to set up additional MCU, TCU and VCU, that is, there is no need for information exchange between the MCU, TCU and VCU, which avoids the problem of network congestion and partial signal loss when the MCU, TCU and VCU use bus signals to interact. The deeply integrated domain controller module 141 improves the signal transmission reliability, thereby ensuring the control and operation reliability of the electronic control system 14.

[0050] In one example, a solenoid proportional valve is provided in the loader 1 , and the domain controller module 141 is connected to the solenoid proportional valve. The domain controller module 141 can control the valve of the hydraulic oil flow and pressure by controlling the solenoid proportional valve to realize control of the loader 1 .

[0051] In order to enable the domain controller module 141 to adjust the torque of the hydraulic motor 132 when the working device is lifted or lowered into place, in one example, Figure 4 As shown, the electronic control system 14 also includes a detection module 142, which is connected to the domain controller module 141. The detection module 142 is used to obtain vehicle information of the loader 1 and send it to the domain controller module 141. The vehicle information includes at least pressure information and position information. The domain controller module 141 receives and displays the vehicle information, allowing the operator to monitor the vehicle information of the loader 1 in real time to determine whether the loader 1 is operating normally. At the same time, the domain controller module 141 can also adjust the torque of the hydraulic motor 132 and the travel motor 133 based on the vehicle information to adjust the operating state of the loader 1 and the working device accordingly.

[0052] In order to enable the detection module 142 to simultaneously obtain the pressure information and positioning information of the loader 1, in one example, the detection module 142 may include a first sensor unit and a second sensor unit, and the first sensor unit and the second sensor unit are respectively connected to the domain controller module 141. The first sensor unit is used to obtain pressure information and send it to the domain controller module 141. The pressure information includes at least return oil blocking pressure information, working pressure information, braking pressure information, lifting pilot pressure information, unloading bucket pilot pressure information and collecting bucket pilot pressure information. The second sensor unit is used to obtain positioning information and send it to the domain controller module 141. The positioning information includes at least leveling positioning information and lifting positioning information.

[0053] In order to enable the detection module 142 to collect and send the pressure information and the position information of the loader 1 to the domain controller module 141, in one example, Figure 5As shown, the detection module 142 may also include a detection unit 1421. For example, the first sensor unit may include a return oil blockage pressure sensor 1422, a working pressure sensor 1423, a brake pressure sensor 1424, a lifting pilot pressure sensor 1425, a bucket unloading pilot pressure sensor 1426, and a bucket collection pilot pressure sensor 1427. The second sensor unit may include a leveling proximity switch 1428 and a lifting proximity switch 1429. Among them, the return oil blocking pressure sensor 1422 is used to obtain the return oil blocking pressure information of the loader 1 and send it to the detection unit 1421, the working pressure sensor 1423 is used to obtain the working pressure information of the loader 1 and send it to the detection unit 1421, the brake pressure sensor 1424 is used to obtain the brake pressure information of the loader 1 and send it to the detection unit 1421, the lifting pilot pressure sensor 1425 is used to obtain the lifting pilot pressure information of the loader 1 and send it to the detection unit 1421, the bucket unloading pilot pressure sensor 1426 is used to obtain the bucket unloading pilot pressure information of the loader 1 and send it to the detection unit 1421, the bucket collection pilot pressure sensor 1427 is used to obtain the bucket collection pilot pressure information of the loader 1 and send it to the detection unit 1421, the leveling in place proximity switch 1428 is used to obtain the leveling in place information of the loader 1 and send it to the detection unit 1421, and the lifting in place proximity switch 1429 is used to obtain the lifting in place information of the loader 1 and send it to the detection unit 1421. The detection unit 1421 collects the vehicle information and sends it to the domain controller module 141. The domain controller module 141 receives and displays the vehicle information, so that the operator can monitor the vehicle information of the loader 1 in real time to determine whether the loader 1 can operate normally. At the same time, the domain controller module 141 can also adjust the torque of the hydraulic motor 132 and the travel motor 133 based on the vehicle information to adjust the action status of the loader 1 and the working device accordingly.

[0054] Here, it is worth noting that the detection module 142 may also include other sensors or other devices to obtain other vehicle information of the loader 1, and this application does not impose any specific restrictions on this.

[0055] In one example, if Figure 6 As shown, the electric control system 14 further includes a wake-up module 143 , which is connected to the domain controller module 141 . The wake-up module 143 is configured to send a wake-up signal to the domain controller module 141 to enable the domain controller module 141 to operate.

[0056] Optionally, the wake-up circuit 143 may be a key switch. When the loader 1 needs to start operation, the operator can switch the key switch to the ON state. The key switch will send a wake-up signal to the domain controller module 141. After the domain controller module 141 is awakened, the domain controller module 141 will begin bus communication with the handle assembly 11, pedal assembly 12, motor assembly 13, and other components in the loader 1. The battery of the loader 1 will provide power to the domain controller module 141 to enable the domain controller module 141 to operate normally. When the loader 1 needs to stop operation, the operator can switch the key switch to the OFF state. The key switch may send a shutdown signal to the domain controller module 141, or it may not send a wake-up signal to shut down the domain controller module 141. There is no specific limitation on this.

[0057] In one example, if Figure 7 As shown, the electronic control system 14 also includes a battery management module 144 and an on-board diagnostic module 145 . The battery management module 144 is connected to the domain controller module 141 and the battery 2 of the loader 1 . The on-board diagnostic module 145 is connected to the battery management module 144 and the domain controller module 141 .

[0058] In this example, when the wake-up circuit 143 is switched to the ON state, the domain controller module 141 is awakened, and bus communication begins between the domain controller module 141, the handle assembly 11, the pedal assembly 12, the motor assembly 13, the battery management module 144, and the on-board diagnostic module 145. When the wake-up circuit 143 is switched to the start (START) position, the domain controller module 141 sends a command to the battery management module 144, which controls the power output of the battery 2 of the loader 1. At this time, the power of the battery 2 is output to the detection module 14, the handle assembly 11, the pedal assembly 12, the motor assembly 13, and other components of the loader 1. After the detection module 14 receives the power provided by the battery 2, it obtains the vehicle information of the loader 1 and sends it to the domain controller module 141. The domain controller module 141 receives the vehicle information and displays it, allowing the operator to monitor the vehicle information of the loader 1 in real time to determine whether the loader 1 is operating normally.

[0059] In this example, the domain controller module 141 and the battery management module 144 can also realize the charging and power-off of the loader 1. For example, when the loader 1 is charging, a charging signal can be sent to the domain controller module 141, so that the domain controller module 141 is activated, and the domain controller module 141 will communicate with the battery management module 144. After the charging conditions are met, the domain controller module 141 will issue a charging instruction to enable the loader 1 to start charging; after charging is completed, the domain controller module 141 will issue a disconnection instruction, and the power can be cut off by pulling out the gun, so that the loader 1 ends charging.

[0060] Optionally, the battery management module 144 is a battery management system (BMS), which can monitor, protect and manage the battery 2 of the loader 1 to ensure that the battery 2 operates safely and efficiently under various working conditions and maximize the service life of the battery 2.

[0061] Optionally, the on-board diagnostic module 145 is an on-board diagnostic system (OBD), and the OBD is capable of monitoring and reporting the operating status and fault information of the loader 1 .

[0062] In one example, if Figure 7 As shown, a human-machine display interface 15 can be provided in the loader 1, and the human-machine display interface 15 is communicated with the domain controller module 141. After the domain controller module 141 receives the vehicle information from the detection module 14, it will send the vehicle information to the human-machine display interface 15 for display, so that the operator can monitor the vehicle information of the loader 1 in real time through the human-machine display interface 15 to determine whether the loader 1 can operate normally.

[0063] Optionally, the human-machine display interface can be an HMI (Human-Machine Interface). The HMI can display information and includes at least a speedometer (displaying the driving speed of the loader 1), a tachometer (displaying the speed of the engine in the loader 1), a speedometer (displaying the driving speed of the loader 1), a fuel gauge (displaying the remaining fuel amount of the loader 1), a temperature gauge (displaying the engine coolant temperature in the loader 1), an oil pressure gauge (displaying the engine oil pressure in the loader 1), a fault indicator light (displaying various fault codes and warning messages), a status display table (such as the action status of working devices such as the bucket, boom and rocker arm), etc.

[0064] In one example, if Figure 8 As shown, the loader 1 may further include an air-conditioning component 16, which is connected to the domain controller module 141 and the on-board diagnostic module 145. The domain controller module 141 is also used to obtain the third state information of the air-conditioning component 16 and switch the working mode of the air-conditioning component 16 based on the third state information, wherein the working mode of the air-conditioning component 16 includes a cooling mode and a heating mode.

[0065] In this example, the third state information is the state information generated in real time when the air-conditioning component 16 changes. When the user operates the air-conditioning component 16 (that is, the state of the air-conditioning component 16 changes), the domain controller module 141 can obtain the third state information corresponding to the air-conditioning component 16 at this time, and switch the working mode of the air-conditioning component 16 based on the third state information to make the air-conditioning component 16 cool or heat.

[0066] For example, Figure 9 As shown, the air conditioning assembly 16 may include an air conditioning control unit 161, an air conditioning panel 162, an air conditioning fan 163, and a water cooling unit 164. The air conditioning control unit 161, the air conditioning panel 162, the air conditioning fan 163, and the water cooling unit 164 are respectively connected to the domain controller module 141 and the on-board diagnostic module 145. When the operating mode of the air conditioning assembly 16 needs to be started or switched, the operator can select the corresponding operating mode on the air conditioning panel 162. When the operator selects the heating mode on the air conditioning panel 162, the air conditioning panel 162 sends a heating instruction to the domain controller module 141. The domain controller module 141 controls the air conditioning control unit 161 based on the heating instruction, causing the evaporator in the air conditioning control unit 161 to operate. At the same time, the air conditioning fan 163 is controlled to rotate based on the heating instruction, so that the air conditioning assembly 16 operates in the heating mode, thereby heating the loader 1. When the operator selects the cooling mode on the air-conditioning panel 162, the air-conditioning panel 162 will send a cooling instruction to the domain controller module 141. The domain controller module 141 will control the air-conditioning control unit 161 based on the cooling instruction, so that the compressor in the air-conditioning control unit 161 works, and at the same time control the air-conditioning fan 163 to rotate based on the cooling instruction, so that the air-conditioning component 16 works in the cooling mode, thereby realizing cooling of the loader 1.

[0067] Optionally, a climate management system (CMP) is provided inside the air conditioning control unit 161, and the climate management system can adjust the temperature and air circulation in the cab.

[0068] Optionally, the air conditioning panel 162 can be an AC air conditioning panel, which is set in the cab of the loader 1. The operator can control and adjust the working status, working mode, temperature, air volume, wind direction, etc. of the air conditioning component 16 through the AC air conditioning panel.

[0069] Optionally, a thermal management system (TMS) is provided inside the water cooling unit 164 .

[0070] In summary, the domain controller module 141 provided by the present application not only integrates the functions of MCU, TCU and VCU, but also integrates the functions of air conditioning controller (Advanced Temperature System, ATS), that is, the domain controller module 141 provided by the present application integrates the functions of multiple control units, and there is no need to set up additional MCU, TCU, VCU and ATS, which reduces the layout of the wiring harness and saves a certain amount of production cost. Secondly, there is no need to set up additional MCU, TCU, VCU and ATS, that is, there is no need for information interaction between MCU, TCU, VCU and ATS, which avoids the problem of network congestion and partial signal loss when bus signals are used to interact between MCU, TCU, VCU and ATS. The deeply integrated domain controller module 141 improves the signal transmission reliability, thereby ensuring the control and operation reliability of the electronic control system 14.

[0071] In one example, if Figure 10 As shown, the domain controller module 141 is provided with a first communication network PCAN, a second communication network BCAN, a third communication network TCAN and a fourth communication network SCAN. The on-board diagnostic module 145 is connected to the domain controller module 141 through the first communication network PCAN, the second communication network BCAN, the third communication network TCAN and the fourth communication network SCAN. The battery management module 144 is connected to the domain controller module 141 and the on-board diagnostic module 145 through the first communication network PCAN. The domain controller module 141 is connected to the air-conditioning component 16 through the second communication network BCAN.

[0072] Among them, the first communication network PCAN serves as the power controller local area network (Controller Area Network, CAN). The first communication network PCAN is responsible for the signal interaction of the high-voltage system of the loader 1, so as to grasp the corresponding information of the battery 2 and the charging pile in real time, and promptly feedback it to the human-machine display interface 15 of the loader 1. The baud rate of the first communication network PCAN can be 500K (kilobaud).

[0073] The second communication network BCAN serves as the vehicle CAN. The second communication network BCAN is responsible for the signal interaction of the low-voltage electrical components of the loader 1. It can complete the collection of signals such as the air-conditioning component 16 (such as the above-mentioned air-conditioning control unit 161, air-conditioning panel 162, air-conditioning fan 163 and water-cooling unit 164), the gearbox, etc., and timely feedback to the display screen of the loader 1. The baud rate of the second communication network BCAN can be 250K.

[0074] The third communication network, TCAN, serves as the vehicle networking CAN (Connected Vehicle Controller Area Network), responsible for remotely transmitting vehicle signals from the loader 1. Its baud rate can be 250 kHz. The fourth communication network, SCAN, serves as the vehicle debugging and fault diagnosis CAN. Its baud rate can be 250 kHz. The domain controller module 141 communicates with the telematics box 17 in the loader 1 via the third and fourth communication networks, TCAN and SCAN. The telematics box 17 is a telematics box (T-Box), which enables wireless communication between the loader 1 and external networks.

[0075] In this example, the communication needs of the entire loader 1 can be achieved through four different communication networks, and corresponding communication networks are set up based on different modules / units, so the communication reliability is high. Compared with the related art that requires communication connections between MCU, TCU, VCU, ATS and other control units, and then the corresponding execution units are controlled by MCU, TCU, VCU, ATS and other control units, this application can achieve communication connections with multiple execution units through a domain controller module 141, and there is no need to set up additional MCU, TCU, VCU, ATS and other control units, that is, there is no need for communication between MCU, TCU, VCU, ATS and other control units, which avoids the problem of communication failure when each control unit communicates directly, reduces the vehicle failure rate of loader 1, and thus improves the operation reliability of loader 1. The domain controller module 141 can also be configured with other communication networks, and this application does not make specific restrictions on this.

[0076] In summary, the domain controller module 141 in the electric control system 14 provided by the present application is connected to multiple components (i.e., the handle component 11, the pedal component 12, the motor component 13, the human-machine display interface 15, and the air conditioning component 16), so that the ports of the domain controller module 141 are fully utilized, avoiding the problem that there are surplus effective ports of the domain controller module 141, resulting in the domain controller module 141 not being fully utilized, wasting the port resources of the domain controller module 141, and reducing the number of codes during software development. Moreover, the domain controller module 141 can obtain the first state information of the handle component 11 and the second state information of the pedal component 12, and control the action of the motor component 13 based on the first state information and / or the second state information, that is, information interaction with the handle component 11 and the pedal component 12, as well as control of the motor component 13 can be achieved through a domain controller module 141. In this way, there is no need to set up additional control circuits or control chips, which reduces the layout of the wiring harness and saves a certain amount of production costs. Secondly, there is no need to set up additional control circuits or control chips, that is, there is no need for information interaction between multiple additional control circuits, which avoids the problem of network congestion and partial signal loss when multiple control circuits use bus signals to interact with each other, improves the reliability of signal transmission, and thus ensures the operational reliability of the electronic control system 14.
