[0022] Figure 1 This is a schematic flowchart of a power supply method for a cockpit domain controller provided in an embodiment of this disclosure. This embodiment is applicable to situations where a cockpit domain controller is powered. This method can be executed by a power supply device for the cockpit domain controller, which can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, PC, or server. Figure 1 As shown, the method includes:

[0023] S110. The chips in the cockpit domain controller are grouped according to multiple dimensions to obtain multiple power supply areas.

[0024] In this embodiment, a group of chips corresponds to a power supply area. The multiple dimensions may include chip category, chip function, and controlled entity dimension. The chip category dimension can be categorized into computing, control, communication, analog, etc., and this embodiment does not impose any limitations on this. The chip function dimension may include functions such as computing and processing data for the entire domain controller, controlling the instruction sequence of the power supply chip, processing detection signals, wireless transmission, video playback, and audio power amplification, and this embodiment does not impose any limitations on this. The controlled entity dimension can be categorized into System-on-Chips (SoC) and / or MCU chips. The multiple dimensions may also include security requirements, constant power requirements, and instruction sequence dimensions. The domain controller includes a computing processing module (SoC chip), a control processing module (MCU chip), a communication module (ETH switch chip, BT-WiFi chip, etc.), peripheral modules (camera, audio input / output, video output, etc.), and a power supply system (DC-CDC chip, LDO chip, etc.). In this embodiment, unlike previous load power demand statistics, each power consumption unit is classified and divided in the form of power supply area. That is, it is grouped according to multiple dimensions to obtain multiple power supply areas, which facilitates subsequent power supply based on power supply areas.

[0025] Optionally, the chips in the cockpit domain controller are grouped according to multiple dimensions to obtain multiple power supply areas, including: grouping the chips in the cockpit domain controller according to the chip category dimension to obtain initial multiple power supply areas; adjusting the initial multiple power supply areas based on the chip function dimension and / or the controlled subject dimension to obtain multiple adjusted power supply areas.

[0026] The power supply area includes a power supply area for the computing processing module, a power supply area for the peripherals of the computing processing module, a power supply area for the control module, and a power supply area for the external interaction module.

[0027] For example, a SoC chip belongs to the computing category and can process data throughout the domain controller. It can belong to the computing processing module power supply area. The computing processing module peripheral power supply area can include chips whose controlled entity is the SoC chip, and whose data originates from the SoC chip. An MCU chip belongs to the control category and can control the instruction sequence of the power supply chip, process detection signals, etc. The MCU chip can belong to the control module power supply area. Non-SoC chips and other chips that interact with external systems belong to the external interaction module power supply area. For example, the external interaction module power supply area can include wireless transmission chips, video playback chips, etc. It should be noted that each power supply area has a corresponding power supply chip, which is used to supply power to the chips in its corresponding power supply area. The power supply chip is used to convert the voltage output by the battery into the voltage required by the power supply area of ​​its respective power supply chip.

[0028] S120. Power the chips in the multiple power supply areas based on the multiple dimensions.

[0029] The dimension mentioned above also includes the instruction sequence dimension. The instruction sequence dimension can be understood as the dimension of timing action instructions. In this embodiment, power can be supplied to chips in multiple power supply areas according to multiple dimensions such as the instruction sequence dimension.

[0030] Optionally, powering the chips in the multiple power supply regions based on the multiple dimensions includes: determining the energy resources of each power supply region according to the chip function dimension; and sequentially powering the chips in each power supply region according to the order corresponding to the energy resources and the instruction sequence dimension.

[0031] Here, energy resources can be understood as energy resources such as voltage and current. In this embodiment, the energy resources such as voltage and current required by the chips in the power supply area can be determined from the perspective of chip function. That is, the required voltage and current energy resources are allocated according to different chip functions, and the chips in each power supply area can be powered sequentially according to the order corresponding to the energy resources and instruction sequence, thereby reducing energy consumption and saving electricity. In other words, this embodiment can improve the efficiency and utilization rate of the selection and design of power supply chips and their peripheral devices from the dimensions of power supply chip model selection, rated output capacity confirmation, and output flow allocation.

[0032] The technical solution of this disclosure involves grouping the chips in the cockpit domain controller according to multiple dimensions to obtain multiple power supply areas; each group of chips corresponds to one power supply area; and power is supplied to the chips in the multiple power supply areas based on the multiple dimensions. This disclosure reduces energy consumption by supplying power to the chips in the multiple power supply areas through multiple dimensions.

[0033] In previous cockpit domain controller development, calculating power demand based on a single electrical load resulted in excessive redundant power supply capacity in the domain controller's power supply system. This embodiment addresses this by grouping the chips in the domain controller according to various dimensions and allocating power resources based on the actual power demand and energy efficiency ratio of different groups. This reduces the introduction of redundant power supply modules (power chips + peripheral discrete components, etc.), achieving cost reduction during development and design while fully utilizing the overall output function of the power supply system. It also improves the interaction efficiency between the power supply system and the control unit, and enhances the efficiency of the power-on process.

[0034] Optionally, after supplying power to the chips in the multiple power supply areas based on the multiple dimensions, the method further includes: monitoring the power supply status of each power supply area to ensure safe power supply to the cockpit domain controller.

[0035] In this embodiment, after the energy resources are allocated and the power supply chips are selected according to the power supply area, the safety and monitoring of the power supply system can be deployed, that is, the power supply working status such as voltage, current, chip action time and operating status of each power supply area can be monitored.

[0036] Optionally, the power supply status of each power supply area is monitored, including: controlling the system base chip to perform a self-test operation; if the self-test operation is successful, the system base chip supplies power to the MCU chip to perform a power-on operation; controlling the MCU chip to perform power-on operations on the power supply chips in the computing processing module power supply area, the computing processing module peripheral power supply area, and the external interaction module power supply area in the order corresponding to the timing instructions; if each power supply area is successfully powered on, the power supply status of the MCU chip is monitored; and the power supply status of the remaining power supply areas is monitored.

[0037] The power supply area of ​​the control module includes the MCU chip. This embodiment also incorporates a system base chip to power the MCU chip and monitor its operating status. In other words, the power supply area of ​​the control module also includes the system base chip.

[0038] In this embodiment, the system's base chip performs a self-test to ensure that the control module does not experience timing errors or malfunctions during power-on. If the self-test is successful, the system's base chip supplies power to the MCU chip to perform the power-on operation. The control MCU chip then performs power-on operations on the power supply chips in the computing processing module's power supply area, the computing processing module's peripheral power supply area, and the external interaction module's power supply area, according to the sequence corresponding to the timing instructions. If all power supply areas are successfully powered on, the power supply status of the MCU chip is monitored. If the MCU chip's power supply status is normal, the power supply status of the remaining power supply areas is monitored.

[0039] The timing instructions are attached to the auxiliary processing unit, which defines the timing instructions and their corresponding specific actions. In other words, the timing instructions can be obtained from the auxiliary processing unit.

[0040] Optionally, the MCU chip is controlled to perform power-on operations on the power supply chips in the power supply areas of the computing processing module, the peripheral power supply areas of the computing processing module, and the external interaction module according to the sequence corresponding to the timing instructions. This includes: during the process of controlling the power supply chips in each power supply area to perform power-on operations according to the timing instructions, detecting whether the power good signal of the power supply chip is normal within a set period; if the power good signal is high within the set period, the power good signal of the power supply chip is normal; and controlling the power supply chip in the next power supply area to perform power-on operations according to the sequence corresponding to the timing instructions; if the power good signal is low within the set period, the power good signal of the power supply chip is abnormal, and a restart command is sent to the power supply chip in the corresponding power supply area to perform a reset.

[0041] The set period can be three periods, with each period being 1 millisecond. In this embodiment, during the power-on operation of the power supply chips in each power supply area according to the timing instructions, the control MCU chip checks whether the powergood signal of the power supply chip is normal within a continuous set period. If the powergood signal is high for all power supply chips within the set period, the power good signal of the power supply chip is normal. Then, the control MCU chip controls the power supply chips in the next power supply area to perform the power-on operation according to the sequence corresponding to the timing instructions, and checks whether the power good signal of the power supply chip in the next power supply area is normal, and so on, until the power-on process of the power supply chips in all power supply areas is completed. If the power good signal is low for all power supply chips within the set period, the power good signal of the power supply chip is abnormal, and a restart command is sent to the power supply chips in the corresponding power supply area to perform a reset.

[0042] In this embodiment, unlike the previous method of simply monitoring the feedback signal of the power supply chip, the present invention inputs the Power Good signal of the power supply chip to the IO pin of the MCU during the power-on process. Debouncing is then performed in the MCU chip, that is, the power good signal of the power supply chip is checked for normality within a continuously set period. If the power good signal of the power supply chip is normal, the power-on process can continue. This avoids the problems of power-on action and timing disorder caused by misjudgment due to voltage overshoot or current rush in traditional detection methods.

[0043] Optionally, the power supply status of the MCU chip is monitored, including: controlling the MCU chip to send a watchdog signal to the system base chip every first set time interval; if the system base chip receives the watchdog signal, the power supply status of the MCU chip is normal; if the system base chip does not receive the watchdog signal, the MCU chip is reset.

[0044] The first set duration can be 10 milliseconds, 6 milliseconds, etc., and this embodiment does not limit this. In this embodiment, after the power-on process is completed, the watchdog function inside the system base chip can be used to monitor the safety of the MCU chip. Specifically, the MCU chip is controlled to send a watchdog signal to the system base chip through the Serial Peripheral Interface (SPI interface) every first set duration. If the system base chip receives the watchdog signal, the power supply and operation of the MCU chip are normal; if the system base chip does not receive the watchdog signal, the MCU chip is reset.

[0045] Optionally, the power supply status of the remaining power supply areas is monitored, including: controlling the power supply chips in the remaining power supply areas to send a power good signal to the MCU chip; if the MCU chip detects the power good signal as low level for a set number of consecutive times, the power supply status of the corresponding power supply chip is abnormal, and the corresponding power supply chip is restarted; if the MCU chip detects the power good signal as high level for a set number of consecutive times, the power supply status of the corresponding power supply chip is normal.

[0046] The remaining power supply areas are those excluding the control module power supply area. The set number of times can be 3. In this embodiment, the power supply status of the remaining power supply areas can be monitored by the MCU chip. Specifically, the power supply chips in the remaining power supply areas send a "power good" signal to the MCU chip. If the MCU chip detects the "power good" signal as low for a set number of consecutive times, it checks whether the power signal ("power good signal") of the power supply chip is normal within a set period. If the "power good" signal is high for the set period, the "power good" signal of the power supply chip is normal; if the "power good" signal is low for the set period, the corresponding power supply chip is restarted. If the MCU chip detects the "power good" signal as high for a set number of consecutive times, the power supply status of the corresponding power supply chip is normal.

[0047] Optionally, the power supply area of ​​the computing processing module includes a SoC chip; monitoring the power supply status of the power supply area of ​​the computing processing module includes: controlling the SoC chip to send a heartbeat signal to the MCU chip every second predetermined time interval; if the MCU chip detects the heartbeat signal, the power supply status of the SoC chip is normal; if the MCU chip does not detect the heartbeat signal, the power supply status of the SoC chip is abnormal, and the SoC chip is restarted.

[0048] The second preset duration can be a few milliseconds, hundreds of milliseconds, etc., and this embodiment does not impose any limitations on it. This embodiment can also monitor the SoC chip via a heartbeat signal. Specifically, the SoC chip is controlled to send a heartbeat signal (high level) to the MCU chip every second preset duration. If the MCU chip detects the heartbeat signal (high level), it indicates that the power supply within the SoC chip is operating normally; if the MCU chip does not detect the heartbeat signal, it indicates that the power supply within the SoC chip is abnormal, and the SoC chip is restarted.

[0049] In this embodiment, after powering on and entering normal working state, the power supply status of each power supply area is monitored. At the same time, if the power supply status is abnormal, the domain controller will determine and record the event and restart the self-powered unit that is abnormal. Through the above technical means, the core modules (SoC chip or MCU chip) in the domain controller are monitored for safety, and the isolation between power supply areas is achieved, which greatly improves the reliability of the domain controller power supply system.

[0050] In existing domain controller power supply systems, power supply safety monitoring relies on the enable pin and feedback output pin of the power chip to transmit signals to the MCU chip or other control units. When the supply voltage is lower or higher than a set value, a feedback signal notifies the control unit to take action. However, this approach cannot perform tasks such as error logging, debouncing, or energy resource calculation and determination when power supply problems occur. This embodiment addresses these issues of power supply safety monitoring and analysis, improving the controller's accuracy in handling unexpected faults and the effectiveness of feedback information.

[0051] Existing domain controllers typically prioritize hardware implementation during power supply system design. When progressing to the software development stage of the control unit, it's necessary to analyze the timing of various power supply chips, detection signals, and other control signals to perform pin assignments and define action times. This embodiment introduces an auxiliary processing unit to complete timing and control unit pin action definitions during the system design process, significantly improving hardware and software development efficiency.

[0052] By introducing an auxiliary processing unit, the time sequence of the power-on actions of the power supply system is defined and controlled. This allows the actions of each power supply chip or on-hook control circuit to be defined in the specific pins of the control module (MCU chip) during the power supply scheme design process. Based on the processing results, software instructions are generated, thereby improving the efficiency of software and hardware development.

[0053] For example, the output of the auxiliary processing unit is shown in Table 1:

[0054] Table 1. Output of the auxiliary processing unit

[0058]

[0059] In Table 1, the first column lists the network names of the power supply chip pins and the timing instructions. The first English name appearing in each of the second columns is the name of the MCU chip pin, such as GPIO XO. The power supply chip pins and MCU chip pins are connected via the network paths corresponding to their network names, and the state of each network is controlled by the MCU chip pins. For example, if an MCU chip pin outputs a high level, the network path connected to that MCU chip pin also goes high, and the power supply chip pin connected to that network path also goes high.

[0060] It should be noted that the chip-based region grouping mechanism can be attached to electronic processing devices or software. The required information to be imported includes: all chips on the load side, including non-terminal power-consuming chips such as level converters; the chip's category; the chip's function in the system; whether it is related to safety; whether it needs to perform actions during system sleep; which core module (SoC chip or MCU chip) it controls or serves; and the time sequence for when actions need to be performed or prohibited. The required rules to be set are: the weight of the evaluation items and the power supply region to which the weighted result belongs.

[0061] It should be noted that the action sequence auxiliary processing unit can be an electronic processing device or software. The required information to import includes: the pin names and serial numbers used by the MCU chip, the names of the required action signals, the power supply area to which the action signals belong, the time range of the action signals in this area, and the post-processing format of the signals. The required configuration rules include: MCU IO configuration rules, the action time of each power supply area (including time intervals, time sequences, etc.), and reminders for batch actions of action signals at the same time.
