Description

Technical Field

[0001] This invention belongs to the field of intelligent power distribution technology, specifically a power distribution method, system, and device based on time-sharing. Background Technology

[0002] With the rapid development of the automotive industry, the wave of vehicle intelligence, connectivity, and electrification is sweeping the globe at an unprecedented pace. This trend has not only profoundly changed the driving experience and functional positioning of automobiles but also placed more stringent demands on their electrical systems. Against this backdrop, the number of electrical devices integrated into vehicles has increased dramatically, from basic lighting and audio systems to advanced driver assistance systems (ADAS), in-vehicle entertainment systems, autonomous driving controllers, and even electric drive systems. The integration of each technology is accompanied by a significant increase in power demand. These devices are not only diverse but also require ever-increasing power to meet increasingly complex functional requirements and high-performance demands.

[0003] However, as a whole, vehicles face significant challenges in their interior space layout and energy management. They must ensure passenger comfort and safety while providing sufficient installation space for the ever-increasing number of electrical devices. More importantly, in the era of electric vehicles pursuing high efficiency and long range, energy management has become a key factor determining vehicle performance and market competitiveness. Therefore, how to rationally allocate and efficiently utilize every bit of power supply under limited energy availability has become a major issue that automakers must address.

[0004] Existing technology discloses a background monitoring and management platform for vehicle equipment power supply system. This background monitoring and management platform includes an application server, a connection routing service cluster and a database service cluster that communicates with the application server, a management terminal and a connection management service cluster. It realizes a platform for comprehensive analysis and centralized management and control of the status and faults of vehicle electrical equipment, and can support real-time monitoring of many vehicles, storage of large amounts of data and real-time data stream processing. However, it still has the problem of tight power supply resources for the whole vehicle. Summary of the Invention

[0005] To save on vehicle power supply resources, this invention proposes a power distribution device and method based on time-sharing.

[0006] One of the objectives of this invention is a power allocation method based on time-sharing, comprising:

[0007] Based on the principle of whether electrical equipment works synchronously, the working time periods of electrical equipment are divided; the working time periods include the entire time period and multiple non-overlapping time periods.

[0008] Power supply resources for the entire vehicle are allocated according to the defined working hours; the allocation methods include:

[0009] When the electrical equipment operates throughout the entire time period: allocate power supply resources separately for that electrical equipment;

[0010] When electrical equipment is involved in vehicle driving safety: allocate power supply resources separately for that electrical equipment;

[0011] When multiple electrical devices under the same insurance specification are located during the same working period, it is prohibited for these multiple electrical devices to share power supply resources;

[0012] When multiple electrical devices are under different insurance specifications, it is prohibited for these multiple electrical devices to share power supply resources.

[0013] The technical effects of the above allocation method are: based on the principle of sharing power supply resources, the allocation method can alleviate the shortage of power supply resources, reduce the overall vehicle layout space, and lower the overall vehicle energy consumption.

[0014] Furthermore, methods for dividing the working hours of electrical equipment include:

[0015] If multiple electrical devices cannot avoid operating simultaneously, then these multiple electrical devices will be divided into the same working period.

[0016] If multiple electrical devices do not operate synchronously, then the multiple electrical devices are divided into different working periods;

[0017] If multiple electrical devices are operating synchronously, but the control strategy can prevent the multiple electrical devices from operating at the same time, then the multiple electrical devices will be divided into different working periods.

[0018] If a certain electrical device may work synchronously with multiple other electrical devices, then the electrical device should be divided into multiple working periods.

[0019] Furthermore, it also includes power supply management for electrical equipment, and the power supply management strategies include:

[0020] Only one electrical device that does not operate continuously can be turned on at any given time.

[0021] When multiple electrical devices share a power source, power supply management is carried out according to the power consumption priority of the devices. When a higher-priority device is not working, a lower-priority user device can start.

[0022] Furthermore, when two electrical devices share a power supply, the power supply management strategy also includes:

[0023] Connect the switch of one electrical device to the coil terminal of the relay, and connect the electrical device to the normally open contact of the relay; connect another electrical device to the normally closed contact of the relay.

[0024] Furthermore, when multiple electrical devices share a power source, the power supply management strategy also includes:

[0025] Each electrical device is equipped with a relay; the switch of each electrical device is connected to the coil terminal of its corresponding relay; each electrical device is connected to the normally open contact of its corresponding relay.

[0026] Furthermore, the common terminal of the relay corresponding to the lower priority electrical equipment is connected to the normally closed contact of the relay of the electrical equipment with a higher priority.

[0027] Furthermore, when there are three electrical devices, with the priority relationship being: priority of the first electrical device > priority of the second electrical device > priority of the third electrical device, their connection relationships include:

[0028] The switch of the first electrical device is connected to the coil terminal of the motor relay of the first electrical device, and the motor of the first electrical device is connected to the normally open contact of the motor relay of the first electrical device; the normally closed contact of the motor relay of the first electrical device is connected to the common terminal of the relay of the second electrical device; the switch of the second electrical device is connected to the coil terminal of the relay of the second electrical device, and the second electrical device is connected to the normally open contact of the relay of the second electrical device, and the normally closed contact of the relay of the second electrical device is connected to the common terminal of the relay of the third electrical device; the switch of the third electrical device is connected to the coil terminal of the relay of the third electrical device, and the motor of the third electrical device is connected to the normally open contact of the relay of the third electrical device.

[0029] A power distribution system based on time-sharing, which achieves the second objective of this invention, includes:

[0030] Working period segmentation module: used to divide the working periods of electrical equipment according to the principle of whether the electrical equipment works synchronously; the working periods include the entire working period and multiple non-overlapping sub-periods;

[0031] Vehicle power supply resource allocation module: used to allocate vehicle power supply resources according to the divided working periods; allocation methods include:

[0032] When the electrical equipment operates throughout the entire time period: allocate power supply resources separately for that electrical equipment;

[0033] When electrical equipment is involved in vehicle driving safety: allocate power supply resources separately for that electrical equipment;

[0034] When multiple electrical devices under the same insurance specification are located during the same working period, it is prohibited for these multiple electrical devices to share power supply resources;

[0035] When multiple electrical devices are under different insurance specifications, it is prohibited for these multiple electrical devices to share power supply resources.

[0036] Furthermore, in the work period segmentation module, the methods for segmenting the work periods of electrical equipment include:

[0037] If multiple electrical devices cannot avoid operating simultaneously, then these multiple electrical devices will be divided into the same working period.

[0038] If multiple electrical devices do not operate synchronously, then the multiple electrical devices are divided into different working periods;

[0039] If multiple electrical devices are operating synchronously, but the control strategy can prevent the multiple electrical devices from operating at the same time, then the multiple electrical devices will be divided into different working periods.

[0040] If a certain electrical device may work synchronously with multiple other electrical devices, then the electrical device should be divided into multiple working periods.

[0041] Furthermore, it also includes a power supply management module for managing the power supply to electrical equipment. The power supply management strategies include:

[0042] Only one electrical device that does not operate continuously can be turned on at any given time.

[0043] When multiple electrical devices share a power source, power supply management is carried out according to the power consumption priority of the devices. When a higher-priority device is not working, a lower-priority user device can start.

[0044] A power distribution device employing the time-sharing power distribution method described above, for achieving the third objective of this invention, comprises:

[0045] Input interface: Used to input the operating time of the electrical equipment;

[0046] Output interface: Wiring diagram for reading the power supply output interface of the electrical device;

[0047] Connection relationship generation module: used to generate wiring layout diagrams based on the working time and priority of the input electrical equipment.

[0048] Furthermore, the device also includes: an audio-visual entertainment domain controller for displaying wiring diagrams and / or fuse layout diagrams on a display screen; the audio-visual entertainment domain controller is also connected to a data interface for reading wiring diagrams or fuse layout diagrams through the data interface.

[0049] The beneficial effects of this invention include:

[0050] 1. Improve power supply efficiency: By dividing and independently allocating power supply resources according to the working time of electrical equipment, unnecessary power supply during non-working hours is avoided, thereby improving the overall efficiency of the vehicle power supply system.

[0051] 2. Enhance system safety: Provide independent power supply resources to electrical equipment related to vehicle driving safety, ensuring that these critical devices can operate stably under any circumstances, thereby enhancing the safety and reliability of vehicle driving;

[0052] 3. Prevent overload risks: It prohibits multiple electrical devices under the same fuse specification from sharing power resources during the same working period, as well as sharing between devices with different fuse specifications that may affect each other. This effectively avoids problems such as excessive current and overload caused by simultaneous operation of equipment, and protects the safety of the power supply system and electrical equipment.

[0053] 4. Optimize energy allocation: Through detailed analysis of the operating characteristics of electrical equipment, precise allocation of power supply resources is achieved, enabling the limited power resources to be used in the most efficient way, extending vehicle range and improving user experience.

[0054] 5. Facilitates troubleshooting and maintenance: The independent power supply design makes it easier to locate and isolate faults in each electrical device, reducing the complexity of troubleshooting and repair and improving maintenance efficiency. Attached Figure Description

[0062] The following detailed embodiments are provided to explain the technical solutions of the claims of this invention, so that those skilled in the art can understand the claims. The scope of protection of this invention is not limited to the following specific embodiments. Any modifications made by those skilled in the art that incorporate the technical solutions of the claims but differ from the following detailed embodiments are also within the scope of protection of this invention.

[0063] Example 1

[0064] Step 1: Divide the working hours of the electrical equipment corresponding to each insurance specification;

[0065] Once the insurance specifications for all electrical equipment in the vehicle are selected, the working hours for each type of electrical equipment are divided. The principles for dividing the working hours include:

[0066] 1) If two or more electrical devices cannot avoid operating simultaneously, these electrical devices shall be assigned to the same working period.

[0067] 2) If two or more electrical devices cannot operate synchronously, these devices should be divided into different working periods;

[0068] 3) If two or more electrical devices may work synchronously, but can be prevented from working at the same time through control strategies that will not cause user complaints, then these electrical devices should be divided into different working periods.

[0069] 4) If a certain electrical device may work synchronously with multiple other electrical devices, then the device shall be divided into multiple working periods.

[0070] Table 1 below shows examples of working hours for electrical equipment. The time periods shown in this table are just one example. These working hours division methods are built into the intelligent power distribution device and can be edited online via external mobile phones, computers, or other portable devices, or the division results completed offline can be received directly.

[0071] Table 1. Division of Working Hours for Electrical Equipment

[0072]

[0073] Step 2: Allocate the power supply resources for the entire vehicle according to the divided working periods;

[0074] After the working time of all electrical equipment in the vehicle is divided, the power supply resources of the vehicle can be allocated. The allocation of power supply resources of the vehicle is automatically completed by the intelligent power distribution device after receiving the working time division results of the vehicle equipment completed in step 1.

[0075] The power supply resource allocation principle for the entire vehicle is built into the intelligent power distribution device, which can be edited, modified, and updated. Taking the fuse box as an example, after matching the time period and fuse specifications of the electrical equipment, the matched output list is input into the intelligent fuse box. The intelligent fuse box combines the list and the power supply resources of the fuse box to complete the power supply resource allocation, and the correspondence between the output positions and the electrical equipment is assigned, which is the wiring diagram of the intelligent fuse box.

[0076] The power supply resources described in this invention include various types of fuses, MOSFETs, codeable protection devices, and other resources. The principles for allocating vehicle-wide power supply resources include:

[0077] 1) Electrical equipment that operates around the clock cannot share insurance resources with other electrical equipment;

[0078] 2) Electrical equipment related to vehicle driving safety is powered independently. Which equipment is related to safety is defined by the working period. At the same time, a preset list of safety-related electrical equipment is stored in the intelligent power distribution device to verify the working division results of the electrical equipment.

[0079] 3) Electrical equipment under the same insurance specification and operating during the same time period shall not share insurance resources;

[0080] 4) Electrical equipment with different insurance specifications are prohibited from sharing insurance resources.

[0081] Step 3: Develop a vehicle power supply strategy based on the defined working periods;

[0082] To optimize the allocation of power supply resources for the entire vehicle and improve the utilization efficiency of these resources, it is necessary to analyze and formulate power supply controller strategies for each electrical device. When formulating these control strategies, the following principles must be followed:

[0083] 1) For electrical equipment that does not operate during all hours, the principle of not causing user complaints should be followed, and the principle of mutual exclusion should be used to prohibit the simultaneous operation of electrical equipment; that is, only one electrical equipment that does not operate during all hours can be turned on at any given time.

[0084] 2) For each electrical device using a shared power supply, a power priority should be set, and power supply management should be carried out according to the priority. Lower priority devices can only operate if higher priority devices are not in operation. The intelligent power distribution device should have a built-in set of device priorities to guide the vehicle's power distribution device in power allocation.

[0085] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0086] The following example illustrates one embodiment of the vehicle power supply strategy of this invention, using a 12V power socket and a speaker sharing the same power supply:

[0087] The control schematic diagram of the 12V power socket and the speaker sharing the power supply is as follows: Figure 2 As shown, the horn and 12V power socket are connected to the two output terminals of a five-pin relay: the 12V power socket is connected to the normally closed contact of the relay, the horn is connected to the normally open contact, and the horn switch is connected to the coil terminal of the relay. When the horn switch is closed, the relay coil is energized. The control logic is as follows:

[0088] When the horn switch is pressed, the horn relay coil is energized, the relay activates, and switches from a normally closed contact to a normally open contact, connecting the horn power supply and simultaneously disconnecting the 12V power socket connected to the normally closed contact of the relay.

[0089] This control strategy avoids the simultaneous operation of the 12V power socket and the speaker, thus achieving the goal of sharing power between the speaker and the 12V power socket.

[0090] The following example illustrates an embodiment of the vehicle power supply strategy for one of the multi-functional electrical devices of this invention, using the shared power supply of the defrosting, electric pedal, and left front door window lift motor as an example:

[0091] First, determine the operating priority of the three electrical devices: rear defroster, power running board, and left front door window lift motor. The operating priorities are as follows:

[0092] Window lift motor > Rear defrost > Electric pedal

[0093] The intelligent power distribution device has preset priorities for electrical devices, which are then called upon by the device when distributing power.

[0094] The schematic diagram of the shared power control for the rear defroster, electric pedal, and left front door window lift motor is shown below. Figure 3 As shown, each electrical device has one control relay. According to the working priority, the electrical device with lower priority is connected to the normally closed contact of the relay of the electrical device with higher priority.

[0095] Taking window lift, rear defroster, and electric pedal as examples, the connection relationships are as follows: the window lift switch is connected to the coil terminal of the window lift motor relay; the window lift motor is connected to the normally open contact of the window lift motor relay; the normally closed contact of the window lift motor relay is connected to the common terminal of the rear defroster relay; the rear defroster switch is connected to the coil terminal of the rear defroster relay; the rear defroster heating wire is connected to the normally open contact of the rear defroster relay; the normally closed contact of the rear defroster relay is connected to the common terminal of the electric pedal relay; the electric pedal switch is connected to the coil terminal of the electric pedal relay; and the electric pedal motor is connected to the normally open contact of the electric pedal relay. The control logic is as follows:

[0096] When the window lift switch is pressed, the window lift motor relay coil is energized, and the power supply to the window lift motor is turned on. At the same time, the normally closed contact of the window lift motor relay connected to the common terminal of the rear defrost relay is opened, thus breaking the power circuit of the rear defrost. Similarly, the power circuit of the electric pedal is broken, so even if the rear defrost switch or the electric pedal switch is pressed, the rear defrost or the electric pedal cannot work.

[0097] When the window lift switch is not pressed, the common terminal of the window lift motor relay is connected to the normally closed contact. When the defrost switch is pressed, the defrost relay is activated, and the common terminal of the defrost relay is connected to the normally open contact, thus connecting the defrost power supply. Therefore, the defrost works, and the electric pedal power circuit cannot be connected at this time.

[0098] If the rear defrost switch is not pressed, pressing the electric pedal switch will activate the electric pedal relay, connecting the electric pedal power supply and making the electric pedal work.

[0099] If the defrost switch or window lift switch is pressed while the electric pedal switch is in operation, the power supply to the electric pedal will be cut off to ensure that higher-priority electrical equipment is supplied with priority.

[0102] Input interface: Used to input the operating time allocation results of the electrical equipment listed in Table 1. Output interface: Used to connect external devices such as mobile phones or computers to achieve the following functions:

[0103] 1) Read the wiring diagram. This diagram guides the correct connection of electrical equipment to the power supply or provides guidance for after-sales maintenance. The wiring diagram is as follows: Figure 5 As shown, the correspondence between the pin positions and the power supply resources is pre-set in the power distribution device; when the power supply resources are fuse boxes, there are many fuses and relays on the fuse boxes. After the fuses and relays are installed, some external interfaces will be led out to connect with the outside. The wiring layout diagram refers to the correspondence between these external interfaces and the pin positions of the fuses and relays.

[0104] 2) Read the insurance layout diagram. In this embodiment, the insurance layout diagram is as follows: Figure 6 As shown, the fuses on the fuse box are fixed, but each fuse can be intelligently assigned to a specific electrical device, with different assignments resulting in different fuse layout diagrams.
