Description
Technical Field
[0001] This application belongs to the field of electronic technology, and in particular relates to an integrated domain device and a control method for the integrated domain device. Background Technology
[0002] In existing vehicles, multiple domain control blocks are used to control different functional modules. For example, when a user starts the vehicle, four domain controllers are required: the motor controller, the battery manager, the power distribution unit, and the vehicle controller. Because these four domain control blocks are currently located in relatively dispersed positions, a large number of wiring harnesses are needed to connect them, resulting in complex and costly overall vehicle wiring harnesses.
[0003] Furthermore, each domain control block includes multiple different components. Due to the dispersed location of the domain control blocks and the excessive length of the connecting harnesses, the acceptance cycle for different components is also too long, increasing the difficulty of subsequent system integration and debugging. Summary of the Invention
[0004] This application provides a control method that integrates an integrated domain device and an integrated domain device, which can optimize the number of vehicle controls and reduce the number of vehicle wiring harnesses.

[0019] The output of the drive module is connected to the input of the drive motor. The drive module is used to transmit the current and voltage sent by the energy transmission module to the drive motor.
[0020] In one possible implementation, the power module also includes a filtering module;
[0021] The filtering module is used to filter harmonics, and the filtering module includes a first filtering module and a second filtering module.
[0022] The input terminal of the first filtering module is connected to the output terminal of the battery cell module, and the output terminal of the first filtering module is connected to the input terminal of the energy transmission module.
[0023] The input of the second filtering module is connected to the output of the energy transmission module, and the output of the second filtering module is connected to the input of the drive module.
[0024] In one possible implementation, the device further includes a cooling channel disposed between the power module, the charging module, and the voltage conversion module, for dissipating heat from the power module, the charging module, and the voltage conversion module.
[0025] Secondly, embodiments of this application provide a control method for an integrated domain device, which is applied to an integrated domain device including a domain control module, a charging module, and a power module.
[0026] The system includes a domain control module, a charging module, and a power module. The output of the domain control module is connected to the input of the charging module and the power module, respectively.
[0027] The domain control module is used to control the charging module to charge the battery module, control the battery module to supply power to the power module, and control the power module to transmit the voltage and current input from the battery module to the drive motor when the vehicle starts.

[0032] The domain control module receives the power level sent by the battery cell module;
[0033] When the domain control module receives a signal that the battery cell module's charge level is less than a preset threshold, it sends a first instruction to the charging module to charge the battery cell module.
[0034] When the domain control module receives a charge of the battery cell module that is greater than or equal to a preset threshold, it sends a second instruction to the power module, which then transmits the input voltage and current of the battery cell module to the drive motor.
[0035] The integrated domain device and its control method provided in this application integrate a domain control module, a charging module, and a power module into a single integrated domain device. Upon receiving startup information, this allows the integrated domain device to control the charging module to charge the battery module, control the battery module to supply power to the power module, and control the power module to transmit the voltage and current input from the battery module to the drive motor, thereby enabling normal vehicle operation. This application overcomes the cumbersome traditional approach requiring three controllers—a motor controller, a battery manager, and a vehicle controller—reducing the number of controllers, the complexity of the vehicle wiring harness, and costs. It also improves the rapid response between different vehicle modules, achieving high control efficiency. Attached Figure Description

[0041] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.
[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0043] With the continuous development and promotion of my country's new energy sector, the market share of new energy vehicles is constantly increasing. The scale of new energy vehicles will continue to expand in the future, and they are poised to replace traditional vehicles. New energy vehicles, compared to traditional vehicles, utilize three core electrical components—battery pack, motor, and electronic control system—as their power source. These main modules include a Power Distribution Unit (PDU), Battery Management System (BMS), Vehicle Control Unit (VCU), Microcontroller Unit (MCU), Onboard Charger (OBC), and Direct Current Converter (DCDC). Therefore, starting a vehicle requires the coordinated operation of controllers such as the battery pack, power distribution unit (PDU), battery management system (BMS), vehicle control unit (VCU), microcontroller unit (MCU), and on-board charger (OBC). Since these controllers are distributed relatively widely within the vehicle, the wiring harness is numerous and complex, resulting in high costs and difficulties in replacing parts later on. Therefore, this application proposes an integrated domain device that can solve or partially solve the above problems.
[0044] Figure 1 A schematic diagram of an integrated domain device provided in one embodiment of this application is shown.
[0045] like Figure 1 As shown, this application embodiment provides an integrated domain device 100, including: a domain control module 101, a charging module 102, and a power module 103. The output terminal of the domain control module 101 is connected to the input terminals of the charging module 102 and the power module 103, respectively.
[0046] The domain control module 101 is used to control the charging module 102 to charge the battery module 105, control the battery module 105 to supply power to the power module 103, and control the power module 103 to transmit the voltage and current input from the battery module 105 to the drive motor when it receives the start information sent by the vehicle controller 104.
[0047] The charging module 102 is used to charge the battery cell module 105, and the output terminal of the charging module is connected to the input terminal of the battery cell module.
[0048] The power module 103 is used to transmit the input voltage and current of the battery cell module 105 to the drive motor for driving the vehicle. The input terminal of the power module 103 is connected to the output terminal of the battery cell module 105, and the output terminal of the power module 103 is connected to the input terminal of the drive motor.
[0049] When a user needs to start the vehicle, they may operate the accelerator pedal, gear shift, etc. The Vehicle Control Unit (VCU) is the core electronic control unit that realizes the vehicle control decision. The VCU can determine the driver's driving intention by collecting signals such as the accelerator pedal, gear shift, and brake pedal. Therefore, after the VCU has the user's driving intention, it will send the vehicle start information to the domain control module 100.
[0050] A domain control module is typically a vehicle's domain controller unit (DCU). The DCU can control the operation of different controllers in the vehicle, so different control modules can be set up in the DCU, such as the charging module, battery cell module, and power module.
[0051] Domain control module 101 can control the charging module to charge the battery cell module. The battery cell module typically provides the main power source for vehicle startup, such as a battery or fuel cell. The charging module is usually an on-board charger (OBC), which is an accessory for conveniently charging digital products anytime, anywhere using the vehicle's power supply. Therefore, the output of the domain control module can be connected to the input of the on-board charger, thereby enabling the domain control module to control the on-board charger to charge the battery cell module.
[0052] Furthermore, the output of the domain control module can also be connected to the input of the battery cell module, thereby enabling the battery cell module to supply power to the power module. The power module can be a power control unit (PCU). The power control unit can manage the voltage and current from the battery cell module and transmit the voltage and current to the drive motor. The PCU can also recover the energy generated by braking and send it back to the battery cell module.
[0053] Meanwhile, the output of the domain control module can also be connected to the input of the power module to control the power module to transmit the voltage and current input from the battery module to the drive motor. The drive motor is a device in the vehicle that can convert electrical energy into mechanical energy, thereby driving the vehicle.
[0054] In this embodiment, the domain control module in the integrated domain device controls the charging module to charge the battery module, controls the battery module to supply power to the power module, and controls the power module to transmit the voltage and current input from the battery module to the drive motor, thereby enabling normal vehicle operation. This overcomes the cumbersome traditional solution that requires multiple controllers, reduces the number of controllers, reduces the complexity of the vehicle wiring harness, and lowers costs.
[0055] In some embodiments, the domain control module includes:
[0056] Domain controller chip.
[0057] The output of the domain controller chip is connected to the input of the charging module and the power module respectively. The domain controller chip is used to control the charging module to charge the battery module, control the battery module to supply power to the power module, and control the power module to transmit the voltage and current input by the battery module to the drive motor.
[0058] like Figure 2 As shown, the TC38x chip can be selected as the domain controller chip. The TC38x chip includes four cores. The first core is responsible for communicating with the battery module, the second core is responsible for communicating with the power control unit (PCU), the third core is responsible for communicating with the vehicle control unit (VCU), and the fourth core can communicate with the battery module, the domain control unit, and the VCU simultaneously. However, the fourth core cannot perform the functions of the first three cores. For example, if the second core fails during vehicle operation, the fourth core can communicate with the PCU to drive the vehicle normally.
[0059] Therefore, after the third core receives the vehicle start information from the VCU, it will send the information to the first and second cores. Then, the first core communicates with the battery module to determine whether the battery module can work properly, and the second core communicates with the PCU to determine whether the PCU can work properly. Finally, the vehicle is driven by the communication between the three cores.
[0060] In some embodiments, the domain control module may further include a query module, which can be a circuit arranged within the domain control module, such as a current sampling circuit, a voltage sampling circuit, or a temperature acquisition circuit. Furthermore, the input terminal of the query module is connected to the output terminal of the domain control chip, and the output terminal of the query module is connected to the input terminals of the drive motor and the battery module, respectively. Therefore, the domain control chip can send query information on voltage, current, and temperature to the drive motor and the battery module through the query module, thereby achieving vehicle start-up control.
[0061] The query module can also include other circuits, such as power supply circuits, isolation communication circuits, resolver circuits, digital input and output (DIO) circuits, high-voltage interlock circuits, and communication circuits, which will not be elaborated here.
[0062] This application integrates operations that traditionally require multiple controllers to work together into a single domain controller chip. It also includes a query module that allows the domain controller chip to control the query module to retrieve information such as the voltage and current of the drive motor and battery module. This enables information exchange between the integrated domain device and external modules, reducing the number of controllers in the vehicle, optimizing the vehicle wiring harness, and ensuring normal vehicle operation – a win-win situation.
[0063] In some embodiments, the integrated domain device further includes:
[0064] The voltage conversion module has its input terminal connected to the output terminal of the charging module, and its output terminal connected to the input terminal of the battery cell module.
[0065] The voltage conversion module is used to convert the voltage input from the charging module into the voltage required by the battery cell module.
[0066] A voltage conversion module (Direct Current-Direct Current converter, DCDC) is a device that converts electrical energy of one voltage value into electrical energy of another voltage value in a DC circuit. Since the voltage output by the charging module is different from the voltage required by the battery cell module, a DCDC module can be set at the output of the charging module. The voltage of the charging module passes through the DCDC module and then charges the battery cell module, thereby protecting the battery cell module.
[0067] In this embodiment, by setting a voltage conversion module between the charging module and the battery cell module, the voltage output by the charging module can be converted into the voltage required by the battery cell module, while also protecting the battery cell module. Furthermore, the output of the DC-DC converter can be connected to other electrical devices in the vehicle to charge them, enabling normal vehicle operation.
[0068] In some embodiments, the power module includes:
[0069] Energy transfer module and drive module.
[0070] The input terminal of the energy transmission module is connected to the cell module, and the output terminal of the energy transmission module is connected to the input terminal of the drive module. The energy transmission module is used to transmit current and voltage to the drive module.
[0071] The output of the drive module is connected to the input of the drive motor. The drive module is used to transmit the current and voltage sent by the energy transmission module to the drive motor.
[0072] The power module can include an energy transmission module and a drive module. The output of the energy transmission module is connected to the input of the drive module, and the output of the drive module is connected to the input of the drive motor. Therefore, the energy transmission module can transmit the voltage and current input from the battery cell module to the drive module, and then the drive module transmits them to the drive motor.
[0073] In some examples, the energy transfer module may include a variety of relays to convert the voltage and current input from the battery module into the voltage and current required to drive the motor. A bus capacitor may also be provided between the energy transfer module and the drive module to store energy.
[0074] In some examples, the drive module can be an insulated gate bipolar transistor (IGBT), and thus can act as a switching device to control the on and off of the drive motor and the energy transfer module.
[0075] In this embodiment, the power module includes an energy transmission module that can convert the voltage and current input from the battery cell module into the voltage and current required by the subsequent drive motor. At the same time, a drive module is set between the energy transmission module and the drive motor as a switching device to control the conduction and cutoff between the drive motor and the energy transmission module, thereby enabling the vehicle to start and stop and achieve normal vehicle operation.
[0076] In some embodiments, the power module further includes a filter module.
[0077] The filtering module is used to filter harmonics, and the filtering module includes a first filtering module and a second filtering module.
[0078] The input terminal of the first filtering module is connected to the output terminal of the battery cell module, and the output terminal of the first filtering module is connected to the input terminal of the energy transmission module.
[0079] The input of the second filtering module is connected to the output of the energy transmission module, and the output of the second filtering module is connected to the input of the drive module.
[0080] Because the switching of the drive module may generate harmonics, a first filter module is set between the cell module and the energy transmission module, and a second filter module is set between the energy transmission module and the drive module. Therefore, the input terminal of the first filter module is connected to the output terminal of the cell module, and the output terminal of the first filter module is connected to the input terminal of the energy transmission module; the input terminal of the second filter module is connected to the output terminal of the energy transmission module, and the output terminal of the second filter module is connected to the input terminal of the drive module.
[0081] By setting up a filtering module, the interference of harmonics in the circuit can be suppressed, thereby preventing them from affecting the normal operation of the drive motor.
[0082] In some embodiments, the device further includes a cooling channel disposed between the power module, the charging module, and the voltage conversion module, for dissipating heat from the power module, the charging module, and the voltage conversion module.
[0083] In practical use, the charging module, voltage conversion module, and power module can be set up adjacent to each other. A heat dissipation channel can be set between the power module and the charging module and voltage conversion module. This heat dissipation channel can dissipate heat for the charging module, voltage conversion module, and power module at the same time, thus reducing the number of heat dissipation channels, making the controller smaller, and reducing the space occupied by the charging module, voltage conversion module, and power module.
[0084] like Figure 3 As shown, this application provides a control method for an integrated domain device, which is applied to an integrated domain device including a domain control module, a charging module, and a power module.
[0085] The system includes a domain control module, a charging module, and a power module. The output of the domain control module is connected to the input of the charging module and the power module, respectively.
[0086] The domain control module is used to control the charging module to charge the battery module, control the battery module to supply power to the power module, and control the power module to transmit the voltage and current input from the battery module to the drive motor when the vehicle starts.
[0087] The charging module is used to charge the battery cell module. The output terminal of the charging module is connected to the input terminal of the battery cell module.
[0088] The power module is used to transmit the input voltage and current of the battery cell module to the drive motor to drive the vehicle. The input terminal of the power module is connected to the output terminal of the battery cell module, and the output terminal of the power module is connected to the input terminal of the drive motor.
[0089] The methods include:
[0090] S310: When the domain control module receives the vehicle's start information, the domain control module sends a query to the battery cell module to check the battery cell module's power level.
[0091] Therefore, after the VCU detects the user's intention to drive, it sends information to the domain control module to start the vehicle. Upon receiving this information, the domain control module sends a query to the battery module to inquire about its battery level and status. As the battery module is the main power source for the power module, when its battery level is insufficient, the power control unit (PCU) cannot operate, and thus the user cannot start the vehicle.
[0092] S320: The domain control module receives the power sent by the battery cell module.
[0093] After receiving a power query from the domain control module, the battery cell module will send its own power level to the domain control module.
[0094] S330: When the domain control module receives a signal that the battery cell module's charge level is less than a preset threshold, it sends a first instruction to the charging module to charge the battery cell module.
[0095] After receiving the power level from the battery module, the domain control module compares it with a preset threshold. If the battery module's power level is less than the preset threshold, it sends a first command to the charging module to charge the battery module. The preset threshold can usually be set manually; under normal circumstances, it is typically 30%. This means that the domain control module will send the first command to the charging module when it confirms that the battery module's power level is less than 30%.
[0096] S340: When the domain control module receives a battery cell module charge that is greater than or equal to a preset threshold, it sends a second instruction to the power module so that the power module can transmit the input voltage and current of the battery cell module to the drive motor.
[0097] When the domain control module receives a power level greater than or equal to a preset threshold from the battery module, the domain control chip sends a second instruction to the power control unit (PCU) so that the power module can transmit the input voltage and current from the battery module to the drive motor, thereby enabling the drive motor to start operating and thus enabling the vehicle to drive normally.
[0098] This application embodiment utilizes a domain control module that, upon receiving vehicle start information from the VCU, interacts with the battery cell module to query its battery level. This interaction determines whether a command needs to be sent to the charging module to charge the battery cell module, thus improving the user's driving experience. Furthermore, the domain control chip can send a second command to the Power Control Unit (PCU) to transmit voltage and current to the drive motor, enabling normal vehicle operation.
[0099] In some embodiments, before the domain control module sends the second instruction to the power module, the method further includes:
[0100] The domain control module sends a query to the battery cell module to check the temperature of the battery cell module.
[0101] When the domain control module sends a query to the battery cell module about its power level, it can also send a query to the battery cell module about its temperature. It is conceivable that if the temperature of the battery cell module is lower than the preset temperature threshold, the battery cell module will also be unable to supply power to the power control unit (PCU) normally. Therefore, querying the temperature of the battery cell module is very necessary.
[0102] The domain control module receives the temperature data sent by the battery cell module.
[0103] It is conceivable that a temperature sensor can be installed in the battery cell module to detect the temperature of the battery cell module. Therefore, after the sensor in the battery cell module detects the temperature of the battery cell module, it will send the temperature to the domain control module.
[0104] When the domain controller chip receives a signal that the temperature of the battery cell module is lower than a preset threshold, it sends a third instruction to the battery cell module to preheat the battery cell module until the temperature is greater than or equal to the preset threshold.
[0105] After the domain control module receives the temperature of the battery module, it compares this temperature with a preset threshold. If the temperature is lower than the preset threshold, the domain control module sends a third command to the battery module to preheat it until the temperature is greater than or equal to the preset threshold. For example, in winter outdoor conditions, the domain control module receives a battery module temperature of -20℃, while the preset threshold is -15℃. Therefore, preheating is required to raise the temperature so that the battery module can supply power to the power control unit (PCU) normally.
[0106] By querying the battery module's power level and temperature simultaneously, it's possible to determine whether the battery module can supply power normally, thereby determining whether the user can drive the vehicle. This improves the user's driving experience. It's conceivable that the domain control module could not only query the battery module's temperature and power level, but also install other sensors in the battery module to transmit signals to the domain control chip.
[0107] In some embodiments, the method further includes:
[0108] The domain control module sends queries to the drive motor to obtain information on the drive motor's temperature and bus voltage.
[0109] After determining that the battery cell module can supply power to the power control unit (PCU) normally, the domain control module needs to query the temperature of the drive motor and the bus voltage before sending the second command to the power module.
[0110] Since vehicle operation relies on the drive motor, it is essential to check the drive motor's temperature and bus voltage before sending the second command. Therefore, bus voltage sampling circuits and temperature sampling circuits can be incorporated into the drive motor to collect its bus voltage and temperature.
[0111] The domain control module receives temperature and bus voltage information sent by the drive motor.
[0112] In some embodiments, the drive motor can send the collected temperature and bus voltage to the query module in the domain control module.
[0113] If the domain control module determines that the temperature of the drive motor is greater than the preset threshold and the bus voltage is within the preset range, it determines that the drive motor can work normally.
[0114] After receiving the temperature of the drive motor and the bus voltage, the domain control module will make a judgment. If it is determined that the temperature is greater than the preset threshold and the bus voltage is within the preset range, the domain control module determines that the drive motor can work normally. Therefore, it can then send a second command to the power control unit (PCU) to enable the power control unit to transmit voltage and current to the drive motor.
[0115] The domain control module in this embodiment determines whether the drive motor can work normally by querying the temperature of the drive motor and the bus voltage before sending the second command to the power control unit (PCU), thereby improving the user's driving experience.
[0116] In some embodiments, after the domain control module sends a second instruction to the power module, the method further includes:
[0117] The domain control module sends a fourth command to the cell module to enable the cell module to supply power to the power module.
[0118] After sending the second instruction to the Power Control Unit (PCU), the domain control module sends a fourth instruction to the cell module, causing the cell module to supply power to the Power Control Unit (PCU).
[0119] The domain control module in this embodiment sends a fourth instruction to the battery cell module, causing the battery cell module to supply power to the power control unit (PCU). As a result, the power control unit (PCU) can transmit voltage and current to the drive motor, thus providing the user with normal driving functions.
[0120] In practice, after the domain control module activates the power module, the drive module within the power module will be turned on. When the battery cell module supplies power to the power control unit (PCU), the voltage output from the battery cell module sequentially passes through the energy transfer module, bus capacitor, and drive module within the power control unit (PCU) before being output. It is conceivable that to mitigate the impact of harmonics generated by the drive module's switching on the voltage, a filter module can be installed at both the input and output terminals of the energy transfer module to improve voltage stability.
