[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The terms "first," "second," "third," and "fourth" in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of operations or units is not limited to the listed operations or units, but may optionally include operations or units that are not listed, or may optionally include other operations or units that are inherent to the process, method, product, or apparatus.

[0038] References herein to "embodiments" mean that a particular feature, result, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] In order to better understand the technical solution of the embodiment of the present application, the electrical system of the vehicle provided in the embodiment of the present application will be described in detail below with reference to FIG1 .

[0040] Please refer to Figure 1, which is a schematic diagram of the architecture of a vehicle electrical system provided by an embodiment of the present application. As shown in Figure 1, the vehicle electrical system 10 includes a central controller 110, a first communication line 111, and M electrical devices 130. The central controller 110 can be communicatively connected to the M electrical devices 130 via the first communication line 111, where M is a positive integer and M>1;

[0041] The electrical device 130 may be used to collect status information of the vehicle and send the status information to the central controller 110 . The status information is related to the function and / or property of the electrical device.

[0042] The central controller 110 may be configured to receive vehicle status information.

[0043] The electrical device 130 may be a sensor or an actuator. This application does not limit the types of sensors and actuators. For example, the sensor may be a pressure sensor, an ultrasonic sensor, an intelligent sensor, etc., and the actuator may be an intelligent actuator. Furthermore, the electrical device 130 may include at least one sensor and / or at least one actuator. For example, if the electrical device 130 is a sensor disposed in a door switch, when a user opens the door, the sensor in the door switch will collect a switch signal and send the switch signal as a form of status information to the central controller 110. If the electrical device 130 is a pressure sensor disposed on a seat, when a user sits in the passenger seat, the pressure sensor on the passenger seat will collect a pressure signal and send the pressure signal as a form of status information to the central controller 110. If the electrical device 130 is an ultrasonic sensor, when there is an obstacle around the vehicle, the ultrasonic sensor will receive an ultrasonic signal reflected by the obstacle and send the ultrasonic signal as a form of status information to the central controller 110.

[0044] In a possible implementation, the M electrical devices include K electrical device groups, where K is a positive integer and K<M;

[0045] An electrical component group includes one or more electrical components, and a distance between two electrical components in an electrical component group including multiple electrical components is smaller than a preset value.

[0046] It should be noted that dividing the M electrical devices 130 into K electrical device groups 140 does not physically encapsulate the multiple electrical devices 130 into one electrical device group, but simply regards multiple electrical devices 130 that meet preset conditions as one electrical device group 140.

[0047] Wherein, in terms of the wiring structure, each electrical component group is electrically connected to the first communication line through the second communication line.

[0048] For example, please refer to Figure 2, which is a schematic diagram of the architecture of a vehicle electrical system provided in another embodiment of the present application. As shown in Figure 2, the vehicle electrical system 10 includes a central controller 110, a power module 120, and an electrical device 130. The central controller 110 is in communication with the electrical device 130, and the central controller 110 is electrically connected to the power module 120;

[0049] The power module 120 may be used to provide electrical energy to the electrical device 130 and the central controller 110 .

[0050] It should be noted that the number and connection method of the first communication lines 111 shown in Figure 2 are merely for the purpose of more clearly illustrating the structure of the vehicle electrical system in the embodiment of the present application and should not constitute a limitation on this application. In practice, the number of first communication lines 111 can be increased or decreased according to actual circumstances and is not limited here.

[0051] Specifically, the electrical device 130 can be distributed in various areas of the vehicle. The electrical device 130 can be connected to the first communication line 111 nearby through the second communication line 112, and then connected to the central controller 110 through the first communication line 111, thereby realizing communication interaction between the central controller 110 and the electrical device 130.

[0052] In a possible implementation, the electrical device 130 communicates and interacts directly with the central controller 110 , and all control instructions for the electrical device 130 in the vehicle are issued by the central controller 110 .

[0053] Optionally, the communication method between the central controller 110 and the electrical device 130 includes, but is not limited to, Ethernet, Controller Area Network (CAN bus protocol), low-cost serial communication network (LIN) and optical communication. If the central controller 110 and the electrical device 130 communicate through these methods, the first communication line 111 and the second communication line 112 can be considered as wired communication lines. Conversely, the communication line between the electrical device 130 and the central controller 110 (such as the first communication line 111 and the second communication line 112) can also be a virtual line (or wireless communication line), and the communication signal can be transmitted through wireless communication, such as Bluetooth, wireless fidelity (WIreless Fidelity, WiFi) or radio frequency technology.

[0054] Optionally, the second communication line includes a second main communication line and one or more second branch communication lines. The one or more second branch communication lines are electrically connected to the first communication line through the second main communication line.

[0055] Exemplarily, the second communication line 112 may include a second communication main line and a second communication branch line. Multiple electrical devices 130 in the same electrical device group 140 may couple their respective second communication branch lines to the second communication main line corresponding to the electrical device group 140 via the same interface. It can be understood that one electrical device group 140 corresponds to one second communication main line. Based on the above, it can be considered that one electrical device group 140 is connected to the first communication line 111 via one second communication main line. Unlike the prior art, which requires the same number of independent communication lines as the number of electrical devices to achieve a one-to-one connection between each electrical device and the central controller, the solution provided in the embodiment of the present application helps to reduce the vehicle's demand for communication lines and / or power cord lengths, thereby reducing the vehicle's manufacturing cost.

[0056] As shown in Figure 2 , the first communication line 111 can comprise a circular, closed circuit. This facilitates the connection of various electrical components to the first communication line 111. For example, the three second electrical components 130 in the upper right corner of Figure 2 can be connected to the first communication line from the upper right corner of the circular, closed circuit, thereby directly connecting to the central controller 110. This can shorten the length of the wiring harness within the vehicle.

[0057] In Figure 2, the encircling closed circuit is rectangular. The upper circuit can be understood as being located in the front compartment of the vehicle, while the lower circuit can be understood as being located in the rear compartment. The circuits on either side can be understood as being located on either side of the vehicle body. This facilitates the convenient access of electrical components in various parts of the vehicle to the first communication circuit 111, thereby enabling direct connection to the central controller 110.

[0058] In one possible implementation, the present application may include electrical components in the same physical area as an electrical component group. The physical area may be understood as a complete and independent component of a vehicle, such as a door, roof, chassis, or seat, etc., without limitation herein.

[0059] In another possible implementation, the embodiment of the present application may regard multiple electrical devices 130 whose distances between each other are less than a preset value as an electrical device group 140, that is, the distance between any two electrical devices 130 in the same electrical device group is less than or equal to a preset value. The preset value is set by technical personnel based on actual conditions and is not limited in this application.

[0060] For example, please refer to Figure 3, which is a schematic diagram of a scenario for determining an electrical component group provided by this application. As shown in Figure 3, it is assumed that a vehicle is equipped with a first electrical component 21, a second electrical component 22, a third electrical component 23, a fourth electrical component 24, a fifth electrical component 25, a sixth electrical component 26, a seventh electrical component 27, an eighth electrical component 28, and a ninth electrical component 29. The distances between the electrical components are shown in Table 1:

[0061] Table 1

[0062] When the preset value is 30, the first electrical device 21, the second electrical device 22, and the third electrical device 23 can be classified into the same electrical device group, the fourth electrical device 24, the fifth electrical device 25, and the sixth electrical device 26 can be classified into the same electrical device group, and the seventh electrical device 27, the eighth electrical device 28, and the ninth electrical device 29 can be classified into the same electrical device group according to the distance values ​​shown in Table 1.

[0063] It should be noted that although FIG3 shows only nine electrical components (or three electrical components), this does not mean that the vehicle or vehicle control system electrical system of the embodiment of the present application can only include nine electrical components (or three electrical components), and should not constitute a limitation on the present application. In practice, the equipment can be equipped according to actual conditions, and the present application does not impose any limitation on this.

[0064] In a possible implementation, when the distance between two electrical components is smaller than a preset value but the two electrical components do not belong to the same physical area, the two electrical components cannot be divided into one electrical component group.

[0065] For example, assuming that the first electrical device 21, the second electrical device 22, the fourth electrical device 24, the fifth electrical device 25, and the sixth electrical device 26 are located in the left door, and the third electrical device 23 is located on the main driver's seat (considered to be the seat close to the left door), in this case, even if the distance between any two of the first electrical device 21, the second electrical device 22, and the third electrical device 23 is less than a preset value, the first electrical device 21, the second electrical device 22, and the third electrical device 23 cannot be classified as the same electrical device group; while the fourth electrical device 24, the fifth electrical device 25, and the sixth electrical device 26 are located in the same physical area (i.e., the left door) and the distance between any two of the fourth electrical device 24, the fifth electrical device 25, and the sixth electrical device 26 is less than a preset value, the fourth electrical device 24, the fifth electrical device 25, and the sixth electrical device 26 can be classified as the same electrical device group.

[0066] Continuing with reference to Figure 2, in one possible embodiment, the number of first communication lines 111 is greater than 1, and the distance at which the second communication line 112 is connected to the central controller 110 through the first communication main line is less than or equal to the distance at which the second communication line 112 is connected to the central controller 110 through the first communication secondary line, then the first communication main line is the first communication line connected to the second communication line 112, and the first communication secondary line is the first communication line other than the first communication main line.

[0067] It should be noted that connecting the electrical device 130 and the first communication line 111 (or the central controller 110) by a proximity connection helps to shorten the time of communication signal transmission.

[0068] In another possible implementation, the central controller 110 may include a first interface 113 and a second interface 114 , and the central controller 110 may be configured to be electrically connected to the first communication line 111 through the first interface 113 and the second interface 114 .

[0069] Optionally, the central controller 110 has multiple first interfaces 113 and / or second interfaces 114, and each first interface 113 and / or second interface 114 can lead to a first communication line 111. For example, if the central controller 110 has a total of three first interfaces 113 and second interfaces 114, the entire vehicle's electrical system 10 can have three first communication lines; if the central controller 110 has a total of four first interfaces 113 and second interfaces 114, the entire vehicle's electrical system 10 can have four first communication lines; if the central controller 110 has a total of five first interfaces 113 and second interfaces 114, the entire vehicle's electrical system 10 can have five first communication lines, and so on.

[0070] It should be noted that the electrical device 130 can communicate and interact with the central controller 110 through any one of the first interface 113 and / or the second interface 114 .

[0071] For example, please refer to FIG4 , which is a schematic diagram of a scenario for distinguishing a first communication line provided in an embodiment of the present application.

[0072] As shown in FIG4 , there are two connection lines between the electrical device 130 and the central controller 110: the second communication line 112 to the left first communication line 31 (the left first communication line 31 is coupled to the first interface 113 of the central controller 110) and the second communication line 112 to the right first communication line 32 (the right first communication line 32 is coupled to the second interface 114 of the central controller 110). Based on the length of these two connection lines, the left first communication line 31 can be considered the first primary communication line, and the right first communication line 32 can be considered the first secondary communication line. In this case, the electrical device 130 preferentially transmits or interacts with the central controller 110 via the second communication line 112 to the left first communication line 31 connection.

[0073] Furthermore, if the left first communication line 31 fails (such as a circuit breaker), the electrical device 130 can transmit status information from the second interface 114 to the central controller 110 through the "second communication line 112-right first communication line 32", and can also receive control instructions issued by the central controller 110 from the second interface 114 through the "second communication line 112-right first communication line 32".

[0074] Optionally, the selection of the power supply line between the electrical device 130 and the power module 120 and the selection of the power supply line between the power module 120 and the central controller 110 may also refer to the selection of the connection line between the electrical device 130 and the central controller 110.

[0075] In some possible implementations, the multiple first communication lines do not interfere with each other.

[0076] In another possible implementation, referring again to FIG2 , the power module 120 is electrically connected to the central controller 110 and the various electrical devices 130. The power module 120 may include at least one second power line interface 121, and the second power line interface 121 is connected to the first communication line 111 via a power line 122. Thus, the power module 120 can be used to electrically connect to the first communication line 111 via the power line 122 connected to the at least one second power line interface 121.

[0077] The power module 120 may be a low-voltage power supply, and the power line 122 may be a low-voltage power line. Specifically, the power module 120 may be connected to the first communication line 111 via the power line 122 to provide power to the central controller 110. The power module 120 may also be connected to the first communication line 111 via the power line 122 to provide power to the electrical device 130 via the second communication line 112.

[0078] In another possible implementation, the electrical device may include a wiring harness connector. For example, please refer to FIG5 , which is a schematic diagram of the structure of an electrical device provided in an embodiment of the present application.

[0079] As shown in Figure 5, the electrical device 130 includes a wiring harness connector 131 and an electrical device body 132. The wiring harness connector 131 is electrically connected to the electrical device body 132. The wiring harness connector 131 has a first communication interface 1311, a first power line interface 1312, and a ground line interface 1313. The electrical device 130 can be connected to the second communication line 112 through the first communication interface 1311. The electrical device 130 receives electrical energy through the first power line interface 1312. The electrical device 130 is grounded through the ground line interface 1313, and the ground line interface 1313 can form a loop with the first power line interface 1312 into which current flows.

[0080] Specifically, with reference to Figures 4 and 5 , the electrical device body 132 can send status information to the central controller 110 via the first communication interface 1311, the second communication line 112, and the first communication line 111, and can also receive control instructions sent by the central controller 110 via the first communication interface 1311. It is understandable that no drive line or signal acquisition line is required between the electrical device body 132 and the central controller 110. The electrical device body 132 can directly obtain status information (such as a sensor obtaining relevant sensor data), convert the status information into a digital signal in a format corresponding to the communication method, and then transmit it to the central controller 110 via the second communication line 112 and the first communication line 111.

[0081] Furthermore, the central controller 110 can determine the control requirements based on the status signals sent by other electrical devices 130, generate control instructions based on the control requirements, and finally transmit them to the corresponding electrical devices 130 via the first communication line 111 and the second communication line 112.

[0082] For example, please refer to Figure 6, which is a structural diagram of a wiring harness connector provided in an embodiment of the present application.

[0083] As shown in Figure 6, the wiring harness connector has six interfaces / pins, including four communication interfaces / pins (corresponding to the first communication interface 1311), one power line interface / pin (corresponding to the first power line interface 1312), and one ground line interface / pin (corresponding to the ground line interface 1313). It should be noted that although four communication interfaces / pins are shown in Figure 6, in practice, the number of communication interfaces / pins can be increased or decreased according to actual conditions, and this application does not impose any restrictions on this.

[0084] It should be noted that the wiring harness connector 131 of the present application must have three types of interfaces: a communication interface (for exchanging communication signals with the central controller 110), a power line interface (for receiving power transmitted by the power module 120), and a ground line interface (for forming a circuit loop). In the simplest case, the wiring harness connector 131 can only be configured with three interfaces, namely, a communication interface / pin, a power line interface / pin, and a ground line interface / pin.

[0085] In a possible implementation, the central controller 110 may also be configured to send a control instruction to the electrical device 130 that sends the status information. The control instruction may be used to control the working state of the electrical device 130, such as startup, standby, and shutdown.

[0086] It should be noted that the embodiments of the present application do not limit the timing of when the central controller 110 receives status information and sends control instructions. That is, the central controller 110 may receive status signals and send control instructions at the same time, or may receive status signals first and then send control instructions, or may send control instructions first and then receive status signals. For example, the central controller 110 sends a control instruction to any electrical device 130 while receiving a status signal from any electrical device 130; or, the central controller 110 sends a control instruction to any electrical device 130 after receiving a status signal from any electrical device 130; or, the central controller 110 sends a control instruction to any electrical device 130 after sending a control instruction to any electrical device 130.

[0087] Accordingly, the embodiments of the present application do not limit the timing of when the electrical device 130 receives the control instruction and sends the status information. That is, the electrical device 130 may receive the control instruction and send the status information at the same time, or may first receive the control instruction and then send the status information, or may first send the status information and then receive the control instruction. For example, the electrical device 130 receives the control instruction sent by the central controller 110 while sending a status signal to the central controller 110; alternatively, the electrical device 130 may first send the status information to the central controller 110 and then receive the control instruction corresponding to the status information sent by the central controller; alternatively, the electrical device 130 may first receive the control instruction sent by the central controller 110 and then send the status information to the central controller 110 based on the control instruction.

[0088] In another possible implementation, the central controller 110 may also be configured to send control instructions to other electrical devices 130. The electrical devices 130 herein refer to electrical devices that do not send status information. In other words, an electrical device 130 may send status information to the central controller 110, and the central controller 110 may send a control instruction to the electrical device 130, or may send a control instruction to another electrical device.

[0089] For example, in conjunction with FIG3 , the central controller 110 may send control information corresponding to the fourth electrical device 24 to the fourth electrical device 24 while receiving the status information sent by the first electrical device 21; or, the central controller 110 may send control information corresponding to the first electrical device 21 to the first electrical device 21 while receiving the status information sent by the first electrical device 21. The control information may be generated based on the status information last sent by the first electrical device 21, or may be generated based on status information sent by electrical devices other than the first electrical device 21 (the status information is also generated before the central controller 110 receives the status information sent by the first electrical device 21 this time). Accordingly, the first electrical device 21 may also send status information corresponding to the first electrical device 21 to the central controller 110 while receiving the control information sent by the central controller 110. The status information may be collected spontaneously and / or periodically by the first electrical device 21, or may be collected under the instruction of the control instruction last sent by the central controller 110.

[0090] For example, please refer to Figure 7, which is a schematic diagram of a vehicle control process according to an embodiment of the present application. Figure 7 takes the electrical components in the vehicle electrical system as an example, including a switch element 61 and a motor element 62.

[0091] As shown in Figure 7, the switch element 61 includes a switch indicator light 611 and a switch sensing element 612, and the motor element 62 includes a motor 621 and a motor position feedback element 622. The central controller 110 establishes a communication connection with the switch element 61 through the switch communication line 63, and the central controller 110 establishes a communication connection with the motor element 62 through the motor communication line 64. Specifically, the switch sensing element 612 can be used to sense a switch signal (such as sensing whether a vehicle door is open, etc.). After the switch sensing element 612 senses the switch signal, it will be transmitted to the central controller 110 through the switch communication line 63. After receiving the switch signal, the central controller 110 will feedback a first control instruction to the switch element 61. The first control instruction is used to control the switch indicator light 611 to switch to the power-on state, that is, to control the switch indicator light 611 to light up. At the same time, after receiving the switching signal, the central controller 110 will send a second control instruction to the motor element 62 through the motor communication line 64. The second control instruction is used to control the motor 621 to switch to the working state. At this time, the motor position feedback element 622 will send the position signal of the motor 621 to the central controller 110 through the motor communication line 64, which helps the central controller 110 to determine the position of the motor element 62, thereby improving the control algorithm.

[0092] In the above example, the switch indicator light 611 is an actuator, which is used to turn the light on / off. The switch sensing element 612 is a sensor, which is used to sense whether the car door is open. Therefore, the switch element 61 can be considered as both an actuator and a sensor. In addition, the motor 621 is an actuator, which is used to switch the operating state according to the control instructions of the central controller 110. The motor position feedback element 622 is a sensor, which is used to send the position signal of the motor 621 to the central controller 110 via the motor communication line 64. Therefore, the motor element 62 can also be considered as both an actuator and a sensor.

[0093] It should be noted that the switch element 61 sends a switch signal to the central controller 110 and receives a first control instruction sent by the central controller 110 through the same communication interface, and the motor element 62 sends a position signal to the central controller 110 and receives a second control instruction sent by the central controller 110 through the same communication interface. Optionally, if it is necessary to implement the diversion of status signals and control instructions, two or more communication interfaces can be set. Exemplarily, the switch element 61 has a first sending communication interface and a first receiving communication interface, wherein the switch element 61 can send a switch signal to the central controller 110 via the first sending communication interface, and the switch element 61 can receive the first control instruction sent by the central controller 110 via the first receiving communication interface. Exemplarily, the motor element 62 has a second sending communication interface and a second receiving communication interface, wherein the motor element 62 can send a position signal to the central controller 110 via the second sending communication interface, and the motor element 62 can receive the second control instruction sent by the central controller 110 via the second receiving communication interface.

[0094] It can be seen that the electrical system of the vehicle using this application can reduce the complexity of vehicle wiring while ensuring that each electrical component can directly communicate with the central controller, helping to reduce the vehicle's failure rate and facilitate the rapid troubleshooting of vehicle fault nodes. Furthermore, this application can also reduce vehicle manufacturing costs by standardizing the models of each wiring harness connector in the vehicle and simplifying the port types of the wiring harness connector.

[0095] Please refer to Figure 8, which is a flow chart of a control method provided in an embodiment of the present application. The method can be applied to the central controller in the vehicle's electrical system. The vehicle's electrical system may include a central controller and electrical components, and the central controller is communicatively connected to the electrical components.

[0096] As shown in FIG8 , the method may include the following operations.

[0097] S801: The electrical device sends status information of the electrical device to the central controller.

[0098] Accordingly, the central controller receives status information of the electrical components.

[0099] The types of electrical components can be referred to above and will not be described in detail here.

[0100] S802: The central controller generates a control instruction according to the status information.

[0101] Optionally, in S803 , the central controller sends a control instruction to the electrical device that sends the status information.

[0102] Correspondingly, the electrical device receives the control information sent by the central controller.

[0103] In a possible implementation, the number of electrical devices is M, and the M electrical devices can be divided into K electrical device groups, where M is a positive integer, M is greater than 1, and K is a positive integer, K<M;

[0104] An electrical component group includes one or more electrical components, and a distance between two electrical components in an electrical component group including multiple electrical components is smaller than a preset value.

[0105] Furthermore, each electrical component group is electrically connected to the first communication line via the second communication line.

[0106] Furthermore, the second communication line may include a second communication main line and one or more second communication branch lines, and the one or more second communication branch lines are electrically connected to the first communication line through the second communication main line.

[0107] It should be noted that dividing M electrical components into K electrical component groups does not physically encapsulate the multiple electrical components into a single electrical component group; rather, it simply treats multiple electrical components that meet preset conditions as a single electrical component group. In terms of wiring structure, multiple electrical components in the same electrical component group can couple their corresponding second communication branch lines to the same second communication main line via the same interface. Therefore, it can be understood that one electrical component group corresponds to one second communication main line. Based on the above, it can be considered that one electrical component group is connected to the first communication line via one second communication main line. This helps reduce the vehicle's demand for communication lines and / or power cables, thereby reducing vehicle manufacturing costs.

[0108] In a possible implementation, the method may further include:

[0109] If there is a fault in the first communication main line, any one of the first communication secondary lines between the central controller and the electrical device is connected, and the central controller receives the electrical device through the first communication secondary line.

[0110] The first main communication line is a first communication line connected to the second communication line, and the first secondary communication line is a first communication line other than the first main communication line.

[0111] Please refer to Figure 9, which is a schematic diagram of the components of a vehicle provided in an embodiment of the present application. As shown in Figure 9, a vehicle 90 includes the vehicle electrical system 10 shown in Figure 1, which can implement the method shown in Figure 8.

[0113] The processor 910 is configured to execute instructions stored in the memory 920 to control the communication interface 930 to receive and send signals and perform the operations in the above method.

[0114] Memory 920 may also include a storage system 921, cache 922, and RAM 923. Cache 922 is a primary memory located between RAM 923 and the CPU. It consists of static random access memory (SRAM) chips and has a relatively small capacity but a much higher speed than main memory, approaching the speed of the CPU. RAM 923 is internal memory that directly exchanges data with the CPU. It can be read and written at any time (except when refreshing) and is very fast. It is typically used as a temporary data storage medium for the operating system or other running programs. These three components combine to realize the functions of memory 920.
