[0002] Many loads need to be deployed in the vehicle, and power is supplied to each load through the vehicle's power supply circuit.
[0003] In the existing technology, when powering the loads of a vehicle, a centralized power distribution architecture is adopted, that is, a central power distribution box is used to uniformly power the various loads of the vehicle.
[0004] However, in the above method, the power lines of all loads need to be drawn from a unified central distribution box, resulting in too many wiring harnesses and making maintenance difficult; in addition, different loads have different power supply requirements, and a unified power supply method will result in the power supply not meeting the power supply requirements of the same load. Summary of the Invention

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0028] Figure 1 A flowchart illustrating the load-based vehicle power distribution method provided in this application. Figure 1 ,like Figure 2 As shown, the method includes:
[0029] S201. Obtain load information of the loads connected to the area controller;
[0030] A zone controller is an intelligent control unit in a vehicle's electronic and electrical architecture used to manage all electronic loads within a specific physical area (such as the front compartment, left / right side of the vehicle body, passenger compartment, rear, etc.), and it has communication, computing, and power distribution control capabilities.
[0031] Load refers to the electronic or electrical equipment in a vehicle compartment that requires electricity, such as headlights, motors, sensors, entertainment systems, and air conditioning actuators.
[0032] Load information is data that describes the current state and requirements of a load, and typically includes, but is not limited to: real-time power / current / voltage; operating mode (on / off / standby); functional priority (e.g., safety-related loads have higher priority); expected runtime or duty cycle; and whether power reduction operation is supported.
[0033] The area controller periodically or event-triggeredly reads load information of all loads within its jurisdiction through built-in sensors, vehicle communication buses such as CAN / LIN / Ethernet, or directly from the load-side acquisition interface. This process forms the basis for subsequent judgments and decisions, ensuring that the system has key data such as "who is currently using electricity, how much electricity is being used, and whether it is important."
[0034] S202. Based on the load information of each load, determine the load level of the vehicle zone corresponding to the area controller;
[0035] Load level is a quantitative assessment of the overall power demand and importance of a vehicle zone, and is usually divided into multiple levels (such as high, medium, low, or 1 to 5 levels). The level classification can be based on: the number or total power ratio of high-priority loads in the zone; whether the total load is close to or exceeds the power distribution limit; and the functional safety requirements of the current vehicle operating mode (such as driving, charging, parking).
[0036] The area controller aggregates and analyzes the load information obtained in S201, such as through weighted summation, threshold comparison, or rule engine judgment, to comprehensively determine the current "load level" of the zone. For example, if multiple safety-related loads (such as steering motors and brake controllers) are operating simultaneously, it is determined to be "high level"; if only lighting or entertainment equipment is operating, it may be "low level". This level reflects the urgency and importance of the zone's demand for electrical resources at the current moment.
[0037] S203. Determine the power distribution method for the vehicle zone corresponding to the area controller based on the load level; and supply power to the loads connected to the area controller based on the determined power distribution method.
[0038] Power distribution mode refers to the specific power supply strategy implemented by the area controller for the loads, which may include: normal full-power supply: meeting the rated demand of all loads; power-limited supply: reducing voltage or limiting current for non-critical loads, causing them to operate at a degraded level; selective power outage: disconnecting low-priority loads in case of severe overload or insufficient battery power; dynamic power scheduling: allocating power resources according to time slices or priority polling. Power supply execution is achieved through intelligent power switches (such as MOSFETs, solid-state relays) within the area controller or in coordination with the main power distribution unit, realizing precise control over the on / off switching or power regulation of each load.
[0039] Based on the load level determined by S202, the area controller queries the preset power distribution strategy table (or receives a strategy from the central domain controller) and selects the matching power distribution method. Subsequently, the controller outputs corresponding power supply commands to each load it manages—for example, maintaining full power operation for critical loads while limiting current to the rear entertainment screens. The entire process achieves "power supply on demand, prioritizing high-power loads while sacrificing low-power loads," optimizing the vehicle's energy efficiency while ensuring driving safety and core functions.
[0040] The load-based vehicle power distribution method provided in this application configures a corresponding area controller for each vehicle zone in the vehicle power distribution system. The controller obtains the load information of the connected loads in real time, determines the current load level of the zone, and then dynamically selects an appropriate power distribution method to provide differentiated power supply to the loads. This achieves the effect of rationally allocating limited electrical energy resources while ensuring the normal operation of critical loads, avoiding overload or energy waste, improving the safety, flexibility and energy efficiency of the whole vehicle power distribution system, and supporting the development needs of future highly integrated and intelligent electronic and electrical architectures.
[0041] Figure 2 A flowchart illustrating the load-based vehicle power distribution method provided in this application. Figure 2 ,like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, a load-based vehicle power distribution method is described in detail, which includes:
[0042] S301. Based on the first mapping relationship and the load information of each load, determine the load level of the vehicle partition corresponding to the load information of each load; or, perform feature aggregation processing on the load information of each load to obtain the feature parameters of the vehicle partition corresponding to the area controller, and determine the load level of the vehicle partition corresponding to the feature parameters according to the second mapping relationship and the feature parameters of the vehicle partition.
[0043] The first mapping relationship represents the correspondence between the load information of the load and the load level of the vehicle partition; the second mapping relationship represents the correspondence between the characteristic parameters of the vehicle partition and the load level of the vehicle partition.
[0044] Optionally, the service load information refers to the quantifiable electrical parameters generated by each electrical device (i.e., load) in the vehicle partition during operation, including but not limited to operating current, rated power, start-stop frequency, continuous operating time, or historical energy consumption data; the load level of the service vehicle partition is a classification identifier of the overall power load intensity within the partition, usually divided into multiple discrete levels (such as low, medium, and high), used to characterize the urgency of the demand for power distribution resources and the degree of safety risk in the area; the first mapping relationship of the service is a preset set of rules or lookup table that directly establishes the correspondence logic between the original load information of one or more loads and the final load level. For example, if the power of any load exceeds the threshold P, the partition level is high.
[0045] Business service feature aggregation processing refers to performing mathematical or statistical operations (such as summation, weighted average, maximum value extraction, variance calculation, etc.) on the load information of multiple loads to generate one or more numerical business service feature parameters that can comprehensively reflect the overall power consumption characteristics of a region.
[0046] The second mapping relationship of business services is another set of rules that maps feature parameters to load levels. It is usually implemented in the form of functions, decision trees or machine learning models and is suitable for fine-grained classification in complex multi-load scenarios.
[0047] When determining the load level of a vehicle zone, the system provides two parallel decision paths. In the first path, the system directly calls a pre-defined first mapping relationship, using the acquired load information of each load as input, and outputs the corresponding vehicle zone load level through rule matching or table lookup. This path is suitable for scenarios with a small number of loads, simple logic, or clear safety thresholds, such as a critical load triggering a high load level upon startup. In the second path, the system first performs feature aggregation processing on the load information of all loads, such as calculating comprehensive indicators like total zone power, peak current, and load activity index, forming one or more feature parameters. Then, based on the pre-defined second mapping relationship, these feature parameters are used as input, and the most suitable load level is derived through a pre-trained classification model or configurable decision rules. This path is suitable for scenarios with multiple coupled loads and complex dynamic changes, and can more accurately reflect the overall power consumption status of the zone. The system can automatically select one of the paths to execute based on the actual configuration or operating environment, thus ensuring both response efficiency and classification accuracy.
[0048] S302. Based on the third mapping relationship and the load level, determine the power distribution method of the vehicle zone corresponding to the load level.
[0049] The third mapping relationship represents the correspondence between load level and power distribution method.
[0050] Optionally, load level refers to the classification of electrical load intensity determined based on the operating status and energy consumption characteristics of each electrical device within the vehicle zone. It is usually divided into several discrete levels (such as Level 1, Level 2, and Level 3, corresponding to low, medium, and high loads, respectively). Power distribution method refers to the specific strategy or power management mode by which the area controller supplies power to each load in its vehicle zone. Common modes include constant battery power mode (continuous power supply), main switch power mode (power supply only when the vehicle is started), and ON power mode (power supply throughout the vehicle after ignition). The third mapping relationship is a preset configuration rule or strategy table that clearly establishes the correspondence logic between different load levels and corresponding power distribution methods. For example, if the load level is high, the ON power mode is used to ensure power supply stability. This mapping relationship can be stored in the non-volatile storage unit of the area controller and can be dynamically adjusted through software updates.
[0051] After obtaining the load level of a vehicle zone, the system invokes a preset third mapping relationship, using the load level as input to query or calculate the matching power distribution method. Specifically, the zone controller reads the load level identifier of the current zone (e.g., "Second Level") and searches for the power distribution strategy associated with that level in the third mapping relationship. Once a match is found, the power supply mode to be adopted for that vehicle zone is determined. For example, if the third mapping relationship specifies "First Level → Battery Constant Power Mode", "Second Level → ON Power Mode", and "Third Level → ON Power Mode with Overcurrent Protection Enabled", the system will select the corresponding power control logic accordingly. This process is entirely automated by the zone controller without manual intervention, ensuring that the power distribution strategy can respond to load changes in real time, balancing power supply reliability and energy efficiency.
[0052] S303. If the determined power distribution mode is the constant battery power mode, then the loads connected to the area controller are continuously powered; if the determined power distribution mode is the main switch power mode, then the loads connected to the area controller are powered only when the vehicle starts; if the determined power distribution mode is the ON power mode, then the loads connected to the area controller are powered at every moment during the vehicle's operation.
[0053] The constant battery power mode means that the zone controller provides uninterrupted power to the connected loads through the vehicle battery regardless of the vehicle's state (including when the engine is off, in sleep mode, or in motion). This mode is typically used for critical equipment with extremely high requirements for power supply continuity, such as anti-theft systems, remote communication modules, or real-time clocks. The master switch power mode means that power is only supplied to the loads when the vehicle's ignition switch is triggered to the start position (i.e., when the vehicle starts). Power is cut off at other times (including after the engine is off or when the ON position is not activated). This mode is suitable for equipment that only needs to operate for a brief moment during startup. The ON power mode means that power is continuously supplied to the loads throughout the entire process when the vehicle's ignition switch is in the ON position (i.e., the vehicle is started and in a drivable or running state). Power is stopped once the vehicle is turned off or exits the ON position. This mode is commonly used for electrical equipment that is highly dependent on driving conditions, such as instrument panels, central control screens, and air conditioning controls.
[0054] In other words, after determining the power distribution method for each vehicle zone, the zone controller executes the corresponding power supply control logic based on the specific type of the power distribution method.
[0055] If the power distribution mode is constant battery power mode, the area controller closes the corresponding power supply path, ensuring that the connected load is always electrically connected to the battery, achieving continuous power supply throughout the entire time domain. If the power distribution mode is master switch power mode, the area controller monitors the vehicle's start signal (such as ignition switch status or start command), and only temporarily connects the power supply when the vehicle starts, maintaining a power-off state after completing the power supply action or when not in the start state. If the power distribution mode is ON power mode, the area controller monitors the vehicle's operating status in real time, and immediately connects the power supply when the vehicle enters the driving or ON position, maintaining the power supply path throughout the driving process until the vehicle is turned off or exits the ON position and then disconnects the power supply.
[0056] The aforementioned power supply control is executed by relays or electronic switching circuits within the area controller, ensuring that power distribution behavior is strictly synchronized with vehicle operating conditions, thereby optimizing vehicle energy consumption management while ensuring functional requirements.
[0057] For example, the area controller is connected to each load in the vehicle partition via electrical connection lines, and the area controller is connected to each load in the vehicle partition via a fuse structure, the fuse structure including a second relay and a fuse, the second relay being connected to the fuse.
[0058] The zone controller establishes a power supply relationship with each load in the vehicle zone through two parallel electrical connection paths: one is a direct electrical connection line for conventional current transmission; the other is a fuse structure that includes protective elements.
[0059] Specifically, the fuse structure consists of a second relay connected in series with the fuse. The second relay acts as a controllable switching element, actively connecting or disconnecting the power supply circuit when needed, while the fuse acts as a passive overcurrent protection device, automatically blowing in the event of a short circuit or abnormally high current to cut off the circuit and prevent equipment damage or wiring overheating. In actual wiring, the output of the area controller is first connected to one end of the second relay, the other end of the second relay is connected to the fuse, and the fuse is then connected to the corresponding load, thus forming a controlled protection path of "controller → second relay → fuse → load". This design allows the system to achieve software-programmable dynamic power supply control through the second relay while retaining the hardware-level safety redundancy of traditional fuses, making it particularly suitable for high-load scenarios requiring both power supply reliability and electrical safety.
[0060] If the load level is Level 1, the control area controller is connected to each load in the vehicle zone via electrical connection lines before supplying power to the loads connected to the area controller based on the determined power distribution method.
[0061] If the load level is level two or three, before powering the loads connected to the area controller based on the determined power distribution method, the control area controller is connected to each load in the vehicle zone through a fuse structure.
[0062] In other words, before performing power supply operations, the area controller selects different electrical connection paths to establish pathways with each load in the vehicle zone based on the determined load level.
[0063] When the load level is the first level (i.e., low load level), it indicates that the power of the electrical equipment in this zone is small and the operating risk is low. The system prioritizes the simplified direct connection method. Before the formal power supply, the control area controller is directly connected to each load through the electrical connection line, omitting the additional protection cascade links, so as to reduce line impedance, reduce energy consumption and improve response efficiency.
[0064] When the load level is level two or three (i.e., medium or high load level), it indicates the presence of high-power devices or multiple loads operating concurrently within the zone, significantly increasing the potential risk of overcurrent or short circuit. In this case, the system connects the zone controller to each load via a fuse structure before powering on. This fuse structure consists of a series combination of a second relay and a fuse. The second relay is actively controlled by the zone controller to enable software-programmable power supply start / stop, while the fuse provides hardware-level overcurrent protection.
[0065] Through this hierarchical connection strategy, the system ensures power supply efficiency in low-load scenarios while introducing a dual electrical protection mechanism for high-load scenarios, taking into account both energy efficiency and safety.
[0066] For example, the area controller is connected to the load via a first relay. When it determines that the vehicle has entered a sleep state, it uses an electromagnetic bistable relay to power down the load connected to each area controller based on a delayed power-down method.
[0067] Optionally, the first relay refers to an electronically controlled switching device installed between the area controller and the load, used to control the connection or disconnection of the power supply path; the first relay is specifically an electromagnetic bistable relay, which is characterized by having two stable states (normally open and normally closed), requiring only a brief power supply to drive it when switching states, and maintaining the current state without continuous power supply after the switching is completed, thus having extremely low power consumption, and is suitable for scenarios sensitive to static current, such as vehicle hibernation.
[0068] Vehicle hibernation refers to a low-power operation mode in which the vehicle control system actively shuts down non-essential electrical equipment and reduces system power consumption after the engine is turned off and a period of no operation delay has elapsed.
[0069] Delayed power-off refers to the process where, after a vehicle enters a sleep state, power to all loads is not immediately cut off. Instead, power-off operations are performed gradually after a controllable delay or in a specific sequence, according to a preset strategy, to ensure that some loads (such as communication modules and data storage units) have enough time to complete the necessary processing before shutdown.
[0070] When the vehicle control system determines that the vehicle has entered a sleep state, the area controller initiates the power-down management process. Since the area controller is connected to the load under its jurisdiction through an electromagnetic bistable relay (i.e., the first relay), the system utilizes the bistable characteristics of this relay to perform a power-off operation without continuously consuming electrical energy.
[0071] Specifically, the area controller sends a brief drive pulse signal to the first relay, switching it from a "closed" state to an "open" state, thereby cutting off the power supply circuit to the corresponding load. This process is implemented using a delayed power-off method: the area controller can wait for a specific time window (such as 30 seconds for remote communication heartbeat reporting) after the hibernation trigger, based on the load's priority, functional attributes, or preset timing, and then send a power-off signal to the bistable relays corresponding to each load one by one. Since the bistable relay does not need to maintain coil current after the state switch, the entire power-off process generates almost no static power consumption after the action is completed, effectively avoiding the battery depletion problem caused by the continuous engagement of traditional monostable relays, and significantly improving the power management reliability of the vehicle in long-term parking or hibernation states.
[0072] The load-based vehicle power distribution method provided in this application configures a corresponding area controller for each vehicle zone in the vehicle power distribution system. The controller obtains the load information of the connected loads in real time, determines the current load level of the zone, and then dynamically selects an appropriate power distribution method to provide differentiated power supply to the loads. This achieves the effect of rationally allocating limited electrical energy resources while ensuring the normal operation of critical loads, avoiding overload or energy waste, improving the safety, flexibility and energy efficiency of the whole vehicle power distribution system, and supporting the development needs of future highly integrated and intelligent electronic and electrical architectures.
