[0015] For any of the aforementioned vehicle-mounted electrical appliances, obtain the usage risk information of the vehicle-mounted electrical appliance;

[0016] Based on the aforementioned usage risk information, each of the aforementioned vehicle-mounted electrical appliances is divided into either the first electrical appliance group or the second electrical appliance group.

[0027] Under the constraint of the first constraint, each of the vehicle-mounted electrical appliances is divided into the first electrical appliance group or the second electrical appliance group.

[0028] Further, under the constraint of the first constraint condition, dividing each of the vehicle-mounted electrical appliances into the first electrical appliance group or the second electrical appliance group includes:

The electrical appliances belonging to the first electrical appliance group are connected to the first power supply bus, while the electrical appliances belonging to the second electrical appliance group are disconnected from the first power supply bus. This allows for the differentiation of different vehicle electrical appliances. Some of the vehicle electrical appliances, belonging to the first electrical appliance group, are powered using the first power supply bus, while other vehicle electrical appliances, belonging to the second electrical appliance group, are not powered using the first power supply bus. This achieves precise power distribution to the vehicle electrical appliances, ensuring that the power supply received by each vehicle electrical appliance matches its lifespan and fault status, which is beneficial for improving troubleshooting of vehicle electrical appliances and enhancing the user experience of the vehicle. Attached Figure Description

[0039] Figure 1 This is a schematic diagram of the power distribution system for a car in the embodiment;

[0040] Figure 2 This is a schematic diagram illustrating the working principle of the power distribution system for automobiles in the embodiment.

[0041] Figure 3 This is a schematic diagram of the power distribution system for a vehicle, including a second power supply bus, as described in the embodiment.

[0042] Figure 4 This is a schematic diagram illustrating the working principle of a power distribution system for automobiles, including a second power supply bus, as shown in the embodiment. Detailed Implementation

[0043] This embodiment provides a power distribution system for an automobile. The power distribution system for the automobile includes a first power supply bus and a switch control module. The power distribution system for the automobile and multiple on-board electrical appliances to which power is distributed are connected to form a power supply system for the automobile, as shown below. Figure 1 As shown.

[0044] Reference Figure 1 The first power supply bus can be in the form of a busbar, and it is connected to a first power supply module, which can specifically be a vehicle-mounted generator, a power battery, or a storage battery, etc. (See reference...) Figure 1 The power supply system for automobiles includes multiple vehicle electrical appliances such as vehicle electrical appliance 1, vehicle electrical appliance 2, vehicle electrical appliance 3, vehicle electrical appliance 4, and vehicle electrical appliance 5. Specifically, vehicle electrical appliance 1 can be a wheel motor, vehicle electrical appliance 2 can be an air conditioner, vehicle electrical appliance 3 can be a headlight, vehicle electrical appliance 4 can be an ambient light, and vehicle electrical appliance 5 can be an audio-visual entertainment system (including components such as a display screen and audio system).

[0045] Figure 1 The switch control module in the system has functions such as data acquisition, data processing, and control of switch connections. For example, the switch control module can acquire data from the outside, process the acquired data, and independently control the connection switches of each vehicle electrical appliance to the first power supply bus based on the processing results.

[0046] For example, Figure 1 In the middle, the switch control module can divide all vehicle electrical appliances, such as vehicle electrical appliance 1, vehicle electrical appliance 2, vehicle electrical appliance 3, vehicle electrical appliance 4 and vehicle electrical appliance 5, into the first electrical appliance group, thereby controlling all vehicle electrical appliances to be connected to the first power supply bus; Figure 2In this system, the switch control module can divide vehicle electrical appliances 1, 3, and 4 into a first electrical appliance group, and divide other vehicle electrical appliances such as 2 and 5 into a second electrical appliance group. This allows it to independently control vehicle electrical appliances 1, 3, and 4 to connect to the first power supply bus, while independently controlling vehicle electrical appliances 2 and 5 to disconnect from the first power supply bus.

[0047] In this embodiment, for vehicle electrical appliances controlled by the switch control module and connected to the first power supply bus, such as... Figure 1 All vehicle electrical appliances, including vehicle electrical appliances 1, vehicle electrical appliances 2, vehicle electrical appliances 3, vehicle electrical appliances 4, and vehicle electrical appliances 5, as well as... Figure 2 Vehicle electrical appliances 1, 3, and 4 are connected to the first power supply bus by the first power supply module, which outputs power supply voltage and current to the first power supply bus, thereby enabling them to perform corresponding component functions.

[0048] In this embodiment, for vehicle electrical appliances that are disconnected from the first power supply bus by the switch control module, such as... Figure 2 The vehicle electrical appliances 2 and 5 in the switch control module can also control these vehicle electrical appliances to remain isolated from the first power supply bus. For example, the switch control module can ground the power supply terminal of these vehicle electrical appliances so that these vehicle electrical appliances will not receive power from the first power supply bus.

[0049] In this embodiment, the switching control module can independently control whether each vehicle electrical appliance is connected to the first power supply bus. For example, the switching control module can control vehicle electrical appliance 1 to connect or disconnect from the first power supply bus without affecting the control of vehicle electrical appliance 2 to connect or disconnect from the first power supply bus.

[0050] In this embodiment, the division of the first and second electrical appliance groups by the switch control module is dynamic. That is, the switch control module can collect and process data in one time period to determine the specific vehicle electrical appliances included in the first and second electrical appliance groups within that time period, and then collect and process new data in the next time period to determine the specific vehicle electrical appliances included in the first and second electrical appliance groups within that time period. In this way, the specific vehicle electrical appliances included in the first and second electrical appliance groups may be different in different time periods, thereby realizing the dynamic division of the first and second electrical appliance groups, as well as the dynamic connection and disconnection of each vehicle electrical appliance with the first power supply bus.

[0051] In this embodiment, by using a switch control module to divide the vehicle electrical appliances into a first electrical appliance group or a second electrical appliance group, and connecting the vehicle electrical appliances belonging to the first electrical appliance group to the first power supply bus while disconnecting the vehicle electrical appliances belonging to the second electrical appliance group from the first power supply bus, different vehicle electrical appliances can be distinguished. Some of the vehicle electrical appliances, namely those belonging to the first electrical appliance group, are powered by the first power supply bus, while other vehicle electrical appliances, namely those belonging to the second electrical appliance group, are not powered by the first power supply bus. This achieves precise allocation of power to the vehicle electrical appliances, ensuring that the power supply received by each vehicle electrical appliance matches its lifespan and fault status, which is beneficial for improving the troubleshooting of vehicle electrical appliances and the user experience of the vehicle.

[0052] For example, in a vehicle equipped with only a single power supply bus (first power bus), the switch control module can detect each in-vehicle electrical appliance. Appliances detected as normal are grouped into a first appliance group, while those detected as abnormal are grouped into a second appliance group. Normal appliances are then connected to the first power supply bus to receive power and perform their functions, while abnormal appliances are not connected to any power supply bus and receive no power. This allows for the suspension of use of abnormal appliances, enabling vehicle users to promptly identify, repair, or replace them, thus improving the user experience.

[0053] In this embodiment, refer to Figure 3 The power distribution system for automobiles also includes a second power supply bus and a second power supply module. The second power supply module can be the same as the first power supply module, such as the same generator, the same power battery, or the same storage battery. Alternatively, the second power supply module can be different from the first power supply module; for example, the first power supply module might be a generator, and the second power supply module might be a storage battery. The first and second power supply buses are electrically isolated to ensure that voltage or current fluctuations on one bus do not affect the other.

[0054] With a second power supply bus configured, the switch control module can connect vehicle electrical appliances belonging to the second electrical appliance group to the second power supply bus, allowing these appliances to receive power from the second power supply bus. For example, refer to... Figure 3 During a certain period, vehicle electrical appliances 1, 3, and 4, belonging to the first electrical appliance group, receive power from the first power supply bus, while vehicle electrical appliances 2 and 5, belonging to the second electrical appliance group, receive power from the second power supply bus; (Refer to...) Figure 4In the next time period, the division between the first electrical appliance group and the second electrical appliance group changes. Vehicle electrical appliances 1, 2 and 5, which belong to the first electrical appliance group, receive power from the first power supply bus, while vehicle electrical appliances 3 and 4, which belong to the second electrical appliance group, receive power from the second power supply bus.

[0055] For example, the switch control module can perform fault detection on each in-vehicle electrical appliance, classifying those appliances for which no fault information was detected (or those with fault information below the threshold, such as "mild") into the first appliance group, and classifying those appliances for which fault information was detected (or those with fault information above the threshold, such as "moderate" or "severe") into the second appliance group. In this way, Figure 3 and Figure 4 The system enables the first power supply module and the first power supply bus to supply power to vehicle electrical appliances that are not faulty or have minor faults, while the second power supply module and the second power supply bus supply power to vehicle electrical appliances that are faulty or have severe faults. This achieves the division and precise allocation of power to vehicle electrical appliances in different states, making it easier for car users or maintenance personnel to troubleshoot faults (for example, simply checking which power supply bus supplies the vehicle electrical appliance can reveal the fault). Moreover, the first power supply bus and the second power supply bus are electrically isolated, which helps prevent the faults of vehicle electrical appliances that are faulty or have severe faults from spreading to vehicle electrical appliances that are not faulty or have minor faults, thereby protecting the safety and user experience of the vehicle.

[0056] In this embodiment, the switch control module can also divide the first electrical appliance group and the second electrical appliance group according to parameters such as the expected remaining service life, achieving the same technical effect. For example, the switch control module can divide the vehicle electrical appliances with an expected remaining service life (absolute length or proportion of the total service life) greater than or equal to a threshold into the first electrical appliance group, and divide the vehicle electrical appliances with an expected remaining service life less than the threshold into the second electrical appliance group.

[0057] In this embodiment, the switch control module can also divide the first electrical appliance group and the second electrical appliance group according to parameters such as usage risk information, which can also achieve the same technical effect.

[0058] For any in-vehicle electrical appliance, its usage risk information indicates the magnitude of the risk of malfunction, fire, etc., if it continues to be used. Specifically, usage risk information can be determined by a single parameter. For example, the usage risk of an in-vehicle electrical appliance typically increases as its expected remaining service life decreases. Therefore, the usage risk information of an in-vehicle electrical appliance can be determined to be negatively correlated with its expected remaining service life.

[0059] In this embodiment, multi-dimensional operating condition information of a vehicle-mounted electrical appliance can also be collected, and artificial intelligence models and other methods can be used to process the multi-dimensional operating condition information to identify the usage risk information of the vehicle-mounted electrical appliance.

[0060] For example, for an on-board electrical appliance such as a motor, parameters such as the percentage of the motor's average speed to its rated speed, the percentage of its average operating temperature to its maximum tolerable temperature, the percentage of its average current to its rated current, and the percentage of its average vibration intensity to its maximum tolerable vibration intensity can be collected to form multi-dimensional operating condition information. Artificial intelligence models and other methods can be used to process this multi-dimensional operating condition information to identify the basic risk information of this on-board electrical appliance.

[0061] In this embodiment, the switch control module can also detect the vehicle's driving task information, which includes information such as the mileage already driven or about to be driven, weather, temperature, humidity, load capacity, and number of passengers. A risk coefficient is determined based on this information. Generally, the longer the driving mileage, the worse the weather, the higher the temperature, the higher the humidity, and the greater the load capacity and number of passengers, the more adverse the impact on the use of in-vehicle electrical appliances. Therefore, the risk coefficient can be set to a positive number and is positively correlated with data such as driving mileage, temperature, humidity, load capacity, and number of passengers.

[0062] After obtaining basic risk information and risk coefficients for an in-vehicle electrical appliance, the switch control module can multiply the basic risk information and the risk coefficients to obtain usage risk information. By obtaining basic risk information and risk coefficients to determine usage risk information, the usage risk of the in-vehicle electrical appliance itself and the promoting or inhibiting effects of the vehicle's driving environment on the risk can be comprehensively considered, thus facilitating a more accurate assessment of the usage risk of the in-vehicle electrical appliance.

[0063] In this embodiment, after obtaining the usage risk information of each vehicle electrical appliance, the switch control module can set a risk threshold and divide the vehicle electrical appliances whose usage risk information is less than or equal to the risk threshold into the first electrical appliance group, and divide the vehicle electrical appliances whose usage risk information is greater than the risk threshold into the second electrical appliance group.

[0064] In this embodiment, by setting up a second power supply bus, vehicle electrical appliances that are in a bad state, such as having a fault, a severe fault, a short expected remaining service life, or a high risk of use, can still receive power from the second power supply bus after being disconnected from the first power supply bus by the switch control module. This maintains the functional operation of the vehicle electrical appliances in the second electrical appliance group, giving car users enough time to troubleshoot and maintain vehicle safety.

[0065] In this embodiment, the first power supply bus and the second power supply bus can use the provided power supply parameters (e.g., the same power supply voltage and maximum power supply current), or they can provide the same power supply parameters (e.g., the second power supply bus provides a lower power supply voltage and a smaller maximum power supply current). For example, when the switch control module classifies vehicle electrical appliances with malfunctions into a second electrical appliance group, the second power supply module can be configured to output lower power supply parameters such as lower power supply voltage and maximum power supply current to the second power supply bus. This helps to reduce the performance degradation of vehicle electrical appliances with malfunctions, reduces the possibility of the malfunctions worsening, and helps to extend the service life of vehicle electrical appliances with malfunctions until the vehicle is repaired, thus ensuring the vehicle's safety and user experience.

[0066] In this embodiment, after obtaining the usage risk information of each vehicle electrical appliance, the switch control module can also perform the following steps to divide the appliance into a first group or a second group:

[0067] A1. Set the first constraint condition;

[0068] A2. Under the constraints of the first constraint, each on-board electrical appliance is divided into either the first electrical appliance group or the second electrical appliance group.

[0069] In step A1, the first constraint condition is specifically that "the sum of the usage risk information of each vehicle-mounted electrical appliance in the first electrical appliance group is equal to the sum of the usage risk information of each vehicle-mounted electrical appliance in the second electrical appliance group." Thus, when executing step A2, the switch control module can first randomly divide each vehicle-mounted electrical appliance into either the first or second electrical appliance group, and then check whether the usage risk information of each vehicle-mounted electrical appliance in the first and second electrical appliance groups satisfies the first constraint condition. If it does, step A2 is completed; otherwise, the vehicle-mounted electrical appliances included in the first and second electrical appliance groups are adjusted, and the usage risk information of each vehicle-mounted electrical appliance in the first and second electrical appliance groups is checked again to see if it satisfies the first constraint condition. If it does, step A2 is completed. If A2 is executed, otherwise, the vehicle electrical appliances included in the first and second electrical appliance groups are adjusted... until the first constraint condition is met, or if the first constraint condition is not met, among the multiple division results of the first and second electrical appliance groups obtained by executing step A2, the division result that is closest to the first constraint condition (for example, the absolute value of the difference between the sum of the usage risk information of each vehicle electrical appliance in the first electrical appliance group and the sum of the usage risk information of each vehicle electrical appliance in the second electrical appliance group is the smallest) is output.

[0070] In this embodiment, after obtaining the usage risk information of each vehicle electrical appliance, the switch control module can also perform the following steps to divide the appliance into a first group or a second group:

[0071] B1. Set the second constraint condition;

[0072] B2. Under the constraint of the second constraint, each on-board electrical appliance is divided into either the first electrical appliance group or the second electrical appliance group.

[0073] In step B1, the second constraint is specifically "the sum of the first deviation and the second deviation is minimized". Specifically, the first deviation is the deviation (i.e., the absolute value of the difference) between the sum of the usage risk information of each vehicle electrical appliance grouped into the first electrical appliance group and the sum of the usage risk information of each vehicle electrical appliance grouped into the second electrical appliance group. The second deviation is the deviation (i.e., the absolute value of the difference) between the sum of the power consumption of each vehicle electrical appliance grouped into the first electrical appliance group and the sum of the power consumption of each vehicle electrical appliance grouped into the second electrical appliance group. Thus, when executing step B2, the switch control module can perform multiple rounds of calculation (the total number of rounds is fixed). In any round of calculation, the switch control module can randomly divide each vehicle electrical appliance into either the first or second electrical appliance group and calculate the corresponding sum of the first and second deviations. After executing all rounds of calculation, the round with the smallest sum of the first and second deviations is selected, and the division result of the first or second electrical appliance group is obtained and output, completing the execution of step B2.

[0074] In this embodiment, the principle of executing steps A1-A2 is as follows: by executing steps A1-A2, the sum of the usage risk information of each vehicle electrical appliance in the first electrical appliance group can be made equal to or nearly equal to the sum of the usage risk information of each vehicle electrical appliance in the second electrical appliance group. This makes the overall risk of each vehicle electrical appliance powered by the first power supply bus close to the overall risk of each vehicle electrical appliance powered by the second power supply bus, reducing the concentrated outbreak of usage risks caused by the imbalance of risks of the vehicle electrical appliances connected to the first and second power supply buses (for example, if a vehicle electrical appliance connected to the second power supply bus fails, the power supply parameters of the second power supply bus will change, exacerbating the failure of other vehicle electrical appliances, and thus causing a sudden change in load on the second power supply bus). This can maintain the stability of the use of the first and second power supply buses even when the performance of the second power supply module or the second power supply bus is insufficient, which is beneficial to maintaining the safety of vehicle use.

[0075] In this embodiment, the principle of executing steps B1-B2 is as follows: Steps B1-B2 are equivalent to further introducing the balance between the overall power consumption of each vehicle electrical appliance powered by the first power supply bus and the overall power consumption of each vehicle electrical appliance powered by the second power supply bus, based on steps A1-A2. This helps to balance the overall usage risk and overall power consumption of the vehicle electrical appliances faced by the first and second power supply buses respectively, and helps to reduce the possibility of failure of the vehicle electrical appliances connected to a certain power supply bus, thus maintaining the safety of vehicle use.

[0076] In this embodiment, a power distribution system and / or a power supply system for a vehicle can be installed on the vehicle, making the power distribution system and / or the power supply system for a vehicle an integral part of the vehicle, thereby enabling the vehicle as a whole to have the technical effects of the power distribution system and / or the power supply system for a vehicle.
