[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0038] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present application and the accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0039] Referring to "embodiment" herein means that a specific feature, result or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0040] For a better understanding of the technical solutions in the embodiments of the present application, the following will be combined with Figure 1 to provide a detailed description of the electrical system of the vehicle provided in the embodiments of the present application.

[0041] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the architecture of an electrical system of a vehicle provided in an embodiment of the present application. The electrical system 10 of the vehicle may include: a central controller 110, a first communication line 111, and M electrical components 130. The central controller 110 may be communicatively connected to the M electrical components 130 via the first communication line 111. M is a positive integer and M>1;

[0042] The electrical component 130 may be used to collect the 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 attribute of the electrical component;

[0043] The central controller 110 may be used to receive the status information of the vehicle.

[0044] Among them, the type of the electrical component 130 can be a sensor or an actuator. This application does not limit the types of sensors and actuators. For example, the sensor can be a pressure sensor, an ultrasonic sensor, an intelligent sensor, etc., and the actuator can be an intelligent actuator. Further, the electrical component 130 can further include at least one sensor and / or at least one actuator. Exemplarily, if the specific form of the electrical component 130 is a sensor disposed in a door switch, when the user opens the door, the sensor in the door switch will collect a switch signal and send the switch signal as a kind of status information to the central controller 110; if the specific form of the electrical component 130 is a pressure sensor disposed on the seat, when a user sits on the passenger seat, the pressure sensor on the passenger seat will collect a pressure signal and send the pressure signal as a kind of status information to the central controller 110; if the specific form of the electrical component 130 is an ultrasonic sensor, when there is an obstacle around the vehicle, the ultrasonic sensor will receive the ultrasonic signal reflected by the obstacle and send the ultrasonic signal as a kind of status information to the central controller 110.

[0045] In a possible implementation manner, the M electrical components include K electrical component groups, where K is a positive integer and K < M;

[0046] One electrical component group includes one or more electrical components, and the distance between any two electrical components in the electrical component group including multiple electrical components is less than a preset value.

[0047] It should be noted that dividing the M electrical components 130 into K electrical component groups 140 is not physically encapsulating the multiple electrical components 130 into one electrical component group, but only regarding multiple electrical components 130 that meet the preset conditions as one electrical component group 140.

[0048] Among them, in terms of the wiring structure, each electrical component group is electrically connected to the first communication line through the second communication line.

[0049] Exemplarily, please refer to Figure 2 , Figure 2 which is a schematic structural diagram of another electrical system of a vehicle provided by an embodiment of this application. As Figure 2 shown, the electrical system 10 of the vehicle can include a central controller 110, a power supply module 120, and electrical components 130. The central controller 110 is communicatively connected to the electrical components 130 and is electrically connected to the power supply module 120;

[0050] The power supply module 120 can be used to supply electrical energy to the electrical components 130 and the central controller 110.

[0051] It should be noted that Figure 2The number and connection mode of the first communication line 111 shown are only for more clearly illustrating the structure of the electrical system of the vehicle according to the embodiments of the present application, and should not limit the present application. Those skilled in the art can increase or decrease the number of the first communication lines 111 according to the actual situation, and no limitation is made herein.

[0052] Specifically, the electrical components 130 can be distributed in various areas of the vehicle. The electrical components 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 via the first communication line 111, so as to realize the communication interaction between the central controller 110 and the electrical components 130.

[0053] In a possible implementation manner, the electrical components 130 directly interact with the central controller 110, and all control instructions for the electrical components 130 in the vehicle are issued by the central controller 110.

[0054] Optionally, the communication mode between the central controller 110 and the electrical components 130 includes but is not limited to Ethernet, Controller Area Network (CAN bus protocol), Local Interconnect Network (LIN), and optical communication. Then, it can be considered that under this communication mode, the first communication line 111 and the second communication line 112 can be wired communication lines. Correspondingly, the communication lines (such as the first communication line 111 and the second communication line 112) between the electrical components 130 and the central controller 110 can also be virtual lines (or wireless communication lines), and the communication signals can be transmitted in a wireless communication manner, such as Bluetooth, Wireless Fidelity (WiFi), or radio frequency technology, etc.

[0055] Optionally, the second communication line includes 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.

[0056] Exemplarily, the second communication line 112 may include a second communication main line and a second communication branch line. Multiple electrical components 130 in the same electrical component group 140 may couple their respective second communication branch lines to the second communication main line corresponding to the electrical component group 140 through the same interface. Thus, it can be understood that one electrical component group 140 corresponds to one second communication main line. Based on the above, it can be considered that one electrical component group 140 is connected to the first communication line 111 through one second communication main line. Different from the prior art that requires setting up the same number of independent communication lines as the number of electrical components to achieve one-to-one connection between each electrical component and the central controller, the method of the embodiment of the present application helps to reduce the demand for the length of communication lines and / or power lines in the vehicle, thereby reducing the manufacturing cost of the vehicle.

[0057] As Figure 2 shown, the first communication line 111 may include a surrounding closed line. This can facilitate each electrical component to be connected to the first communication line 111 nearby. For example Figure 2 the three second electrical components 130 in the upper right corner can be connected to the first communication line from the upper right corner of the circular closed line nearby, so as to achieve direct connection to the central controller 110. This can shorten the length of the wire harness in the vehicle.

[0058] Figure 2 In, the surrounding closed line is rectangular. The line located above can be understood as being arranged in the front cabin of the vehicle, and the line located below can be understood as being arranged in the rear cabin of the vehicle. The lines located on both sides can be understood as being arranged on both sides of the vehicle body respectively. In this way, it can facilitate the electrical components located in various parts of the vehicle to be connected to the first communication line 111 nearby, so as to achieve direct connection to the central controller 110.

[0059] In a possible implementation manner, the embodiment of the present application may use the electrical components in the same physical area as an electrical component group. This physical area can be understood as a complete and independent component in the vehicle, such as a door, a roof, a chassis, or a seat, etc., which is not limited herein.

[0060] In another possible implementation manner, the embodiment of the present application may regard multiple electrical components 130 with a distance less than a preset value between each other as an electrical component group 140, that is, the distance between any two electrical components 130 in the same electrical component group is less than or equal to the preset value, and the preset value is set by those skilled in the art according to the actual situation, which is not limited in the present application.

[0061] Exemplarily, please refer to Figure 3 , Figure 3 which is a schematic diagram of a scenario for determining electrical components provided by the present application. As Figure 3As shown in the figure, assume that there are 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 inside the vehicle. The distances between each electrical component are shown in Table 1:

[0062]

[0063]

[0064] Table 1

[0065] When the preset value is 30, the first electrical component 21, the second electrical component 22, and the third electrical component 23 can be determined as the same electrical component according to the distance values shown in Table 1, the fourth electrical component 24, the fifth electrical component 25, and the sixth electrical component 26 can be determined as the same electrical component, and the seventh electrical component 27, the eighth electrical component 28, and the ninth electrical component 29 can be determined as the same electrical component.

[0066] It should be noted that although Figure 3 only nine electrical components (or three electrical components) are shown, it does not mean that the electrical system of the vehicle or the vehicle control system in the embodiments of the present application can only include nine electrical components (or three electrical components), which should not constitute a limitation to the present application. Those skilled in the art can configure the equipment according to the actual situation, and the present application does not make any restrictions here.

[0067] Correspondingly, when the distance between two electrical components is less than the preset value, but these two electrical components do not belong to the same physical area, they cannot be classified as one electrical component.

[0068] Exemplarily, assume that the first electrical component 21, the second electrical component 22, the fourth electrical component 24, the fifth electrical component 25, and the sixth electrical component 26 are located on the left door, and the third electrical component 23 is located on the driver's seat (regarded as the seat close to the left door). Even if the distances between the first electrical component 21, the second electrical component 22, and the third electrical component 23 are less than the preset value pairwise, the first electrical component 21, the second electrical component 22, and the third electrical component 23 cannot be determined as the same electrical component. However, the fourth electrical component 24, the fifth electrical component 25, and the sixth electrical component 26 are located in the same physical area (i.e., the left door), and the distances between them are less than the preset value pairwise, then the fourth electrical component 24, the fifth electrical component 25, and the sixth electrical component 26 can be determined as the same electrical component.

[0069] Continue to refer to Figure 2, in a possible implementation, the number of the first communication lines 111 is greater than 1, the distance from the second communication line 112 to the central controller 110 connected through the first communication main line is less than or equal to the distance from the second communication line 112 to the central controller 110 connected through the first communication secondary line. The first communication main line is the first communication line that is connected and conducted with the second communication line 112, and the first communication secondary line is the first communication line other than the first communication main line.

[0070] It should be noted that connecting the electrical component 130 to the first communication line 111 (or the central controller 110) in a way of connecting nearby helps to shorten the transmission time of communication signals.

[0071] 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 used to be electrically connected to the first communication line 111 through the first interface 113 and the second interface 114.

[0072] Optionally, there may be multiple first interfaces 113 and / or second interfaces 114 in the central controller 110, and each first interface 113 and / or second interface 114 may lead out a first communication line 111. Exemplarily, if the total number of the first interface 113 and the second interface 114 of the central controller 110 is 3, then there may be 3 first communication lines in the electrical system 10 of the whole vehicle; if the total number of the first interface 113 and the second interface 114 of the central controller 110 is 4, then there may be 4 first communication lines in the electrical system 10 of the whole vehicle; if the total number of the first interface 113 and the second interface 114 of the central controller 110 is 5, then there may be 5 first communication lines in the electrical system 10 of the whole vehicle, and so on.

[0073] It should be noted that the electrical component 130 can communicate with the central controller 110 through any one of the first interface 113 and / or the second interface 114.

[0074] Exemplarily, please refer to Figure 4 , Figure 4 which is a schematic diagram of a scenario for distinguishing the first communication line provided by the embodiment of the present application.

[0075] As Figure 4As shown, there are two connection lines between the electrical component 130 and the central controller 110: "Second communication line 112 - Left first communication line 31 (the left first communication line 31 is coupled to the first interface 113 of the central controller 110)" and "Second communication line 112 - Right first communication line 32 (the right first communication line 32 is coupled to the second interface 114 of the central controller 110)". In terms of the lengths of the two connection lines, the left first communication line 31 can be regarded as the main first communication line, and the right first communication line 32 can be regarded as the secondary first communication line. The electrical component 130 preferentially selects to transmit or exchange signals with the central controller 110 through the connection path of "Second communication line 112 - Left first communication line 31".

[0076] Furthermore, if the left first communication line 31 fails (such as an open circuit), the electrical component 130 can transmit the status information into the central controller 110 through the "Second communication line 112 - Right first communication line 32" from the second interface 114, and can also receive the control instructions sent by the central controller 110 from the second interface 114 through the "Second communication line 112 - Right first communication line 32".

[0077] Optionally, the selection of the power supply line between the electrical component 130 and the power supply module 120, and the selection of the power supply line between the power supply module 120 and the central controller 110 can also refer to the above method.

[0078] In some possible implementation manners, the first communication lines do not interfere with each other.

[0079] In another possible implementation manner, continue to refer to Figure 2 , the power supply module 120 is electrically connected to the central controller 110 and each electrical component 130. The power supply module 120 may include at least one second power supply line interface 121, and the second power supply line interface 121 is connected to the first communication line 111 through a power supply line 122. In this way, the power supply module 120 can be used to be electrically connected to the first communication line 111 through the power supply line 122 connected by at least one second power supply line interface 121.

[0080] Among them, the power supply module 120 can be a low-voltage power supply, and the power supply line 122 can be a low-voltage power supply line. Specifically, the power supply module 120 can be connected to the first communication line 111 through the power supply line 122 to achieve the effect of supplying power to the central controller 110; the power supply module 120 can also be connected to the first communication line 111 through the power supply line 122, and then supply electrical energy to the electrical component 130 through the second communication line 112.

[0081] In another possible implementation manner, the electrical component may include a wire harness connector. Exemplarily, please refer to Figure 5 , Figure 5A structural schematic diagram of an electrical component provided by an embodiment of the present application.

[0082] As Figure 5 shown, the electrical component 130 includes a wire harness connector 131 and an electrical component body 132. The wire harness connector 131 is electrically connected to the electrical component body 132. The wire harness connector 131 may include a first communication interface 1311, a first power supply line interface 1312, and a ground wire interface 1313. The electrical component 130 may be connected to a second communication line 112 through the first communication interface 1311. The electrical component 130 receives electrical energy through the first power supply line interface 1312. The electrical component 130 is grounded through the ground wire interface 1313. The ground wire interface 1313 may form a loop with the first power supply line interface 1312 where current flows in.

[0083] Specifically, in combination with Figure 4 and Figure 5 , the electrical component body 132 may send status information to the central controller 110 through the first communication interface 1311, the second communication line 112, and the first communication line 111, and may also receive control instructions sent by the central controller 110 through the first communication interface 1311. It can be understood that there is no need for a driving line and a signal acquisition line between the electrical component body 132 and the central controller 110. The electrical component body 132 can directly obtain status information (such as the relevant sensor data obtained by a sensor), 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 through the second communication line 112 and the first communication line 111.

[0084] Furthermore, the central controller 110 may determine the control requirements according to the status signals sent by other electrical components 130, generate control instructions according to the control requirements, and finally transmit them to the corresponding electrical components 130 through the first communication line 111 and the second communication line 112.

[0085] Exemplarily, please refer to Figure 6 , Figure 6 A structural schematic diagram of a wire harness connector provided by an embodiment of the present application.

[0086] As Figure 6 shown, the wire harness connector may include 6 interfaces / pins, including four communication interfaces / pins (corresponding to the above-mentioned first communication interface 1311), one power supply line interface / pin (corresponding to the above-mentioned first power supply line interface 1312), and one ground wire interface / pin (corresponding to the above-mentioned ground wire interface 1313). It should be noted that although Figure 6 shows four communication interfaces / pins, those skilled in the art can choose to increase or decrease the number of communication interfaces / pins according to the actual situation, and the present application does not limit this here.

[0087] It can be considered that the wire harness connector 131 must have three types of interfaces: a communication interface (for exchanging communication signals with the central controller 110), a power supply line interface (for receiving electrical energy transmitted by the power supply module 120), and a ground line interface (for forming a circuit loop). In the simplest case, the wire harness connector 131 may only need to be configured with three interfaces, namely, a communication interface / pin, a power supply line interface / pin, and a ground line interface / pin.

[0088] In a possible implementation manner, the central controller 110 can also be used to send control instructions to the electrical device 130 that sends status information. Among them, the control instructions can be used to control the working state of the electrical device 130, such as starting, standby, and shutting down, etc.

[0089] It should be noted that the embodiments of the present application do not limit the timing of the central controller 110 receiving status information and sending control instructions. That is, the central controller 110 can receive status signals and send control instructions simultaneously, or can receive status signals first and then send control instructions, or can also send control instructions first and then receive status signals. Exemplarily, while receiving the status signal sent by any electrical device 130, the central controller 110 can also send a control instruction to any electrical device 130; or, after receiving the status signal sent by any electrical device 130, the central controller 110 sends a control instruction to any electrical device 130; or after sending a control instruction to any electrical device 130, the central controller 110 receives the status signal sent by any electrical device 130.

[0090] Correspondingly, the embodiments of the present application do not limit the timing of the electrical device 130 receiving control instructions and sending status information either. That is, the electrical device 130 can receive control instructions and send status information simultaneously, or can receive control instructions first and then send status information, or can also send status information first and then receive control instructions. Exemplarily, while sending a status signal to the central controller 110, the electrical device 130 can also receive the control instruction sent by the central controller 110; or, the electrical device 130 can first send status information to the central controller 110 and then receive the control instruction corresponding to the status information sent by the central controller; or, the electrical device 130 can first receive the control instruction sent by the central controller 110 and then send status information to the central controller 110 based on this control instruction.

[0091] In another possible implementation manner, the central controller 110 can also be used to send control instructions to other electrical devices 130. Here, the electrical device 130 refers to an electrical device that has not sent status information. That is to say, an electrical device 130 can send status information to the central controller 110, and the central controller 110 can send a control instruction to this electrical device 130, or can send a control instruction to another electrical device.

[0092] Exemplarily, in combination with Figure 3 , while receiving the status information sent by the first electrical component 21, the central controller 110 can send control information corresponding to the fourth electrical component 24 to the fourth electrical component 24; alternatively, while receiving the status information sent by the first electrical component 21, the central controller 110 can send control information corresponding to the first electrical component 21 to the first electrical component 21, and this control information can be generated based on the status information sent by the first electrical component 21 last time, or can be generated based on the status information sent by other electrical components other than the first electrical component 21 (this status information is also before the central controller 110 receives the status information sent by the first electrical component 21 this time). Correspondingly, while receiving the control information sent by the central controller 110, the first electrical component 21 can also send status information corresponding to the first electrical component 21 to the central controller 110, and this status information can be spontaneously and / or periodically collected by the first electrical component 21, or can be collected under the instruction of the control instruction sent by the central controller 110 last time.

[0093] Exemplarily, please refer to Figure 7 , Figure 7 which is a schematic diagram of a vehicle control process scenario provided by an embodiment of the present application. Figure 7 Taking the electrical components in the vehicle's electrical system including a switch element 61 and a motor element 62 as an example.

[0094] As Figure 7 shown, 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 a switch communication line 63, and the central controller 110 establishes a communication connection with the motor element 62 through a motor communication line 64. Specifically, the switch sensing element 612 can be used to sense a switch signal (such as sensing whether a car door is opened, etc.), and 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, and the first control instruction is used to control the switch indicator light 611 to switch to the powered-on state, that is, to control the switch indicator light 611 to light up. At the same time, after receiving the switch signal, the central controller 110 will send a second control instruction to the motor element 62 through the motor communication line 64, and 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 determine the position of the motor element 62, so as to improve the control algorithm.

[0095] In the above example content, the switch indicator 611 is an actuator, and the switch indicator 611 is used to perform the action of turning the light on / off. The switch sensing element 612 is a sensor, and the switch sensing element 612 is used to sense whether the vehicle door is opened. Then, it can be considered that the switch element 61 is both an actuator and a sensor. Similarly, the motor 621 is an actuator, and the motor 621 is used to switch the working state according to the control instruction of the central controller 110. The motor position feedback element 622 is a sensor, and the motor position feedback element 622 is used to send the position signal of the motor 621 to the central controller 110 through the motor communication line 64. Then, it can also be considered that the motor element 62 is both an actuator and a sensor.

[0096] It should be noted that the switch element 61 sends a switch signal to the central controller 110 and receives the first control instruction sent by the central controller 110 through the same communication interface. The motor element 62 sends a position signal to the central controller 110 and receives the second control instruction sent by the central controller 110 through the same communication interface. Optionally, if it is necessary to implement the shunt of the status signal and the control instruction, two or more communication interfaces can be set. Exemplarily, a technician can set a first sending communication interface and a first receiving communication interface on the switch element 61. Among them, 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. The technician can set a second sending communication interface and a second receiving communication interface on the motor element 62. Among them, 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.

[0097] It can be seen that while ensuring that each electrical component can directly communicate with the central controller, the complexity of vehicle wiring is reduced, which helps to reduce the failure rate of the vehicle and also helps technicians quickly troubleshoot the fault nodes of the faulty vehicle. Further, the present application can also simplify the port type of the wire harness connector by unifying the models of the wire harness connectors in the vehicle, thereby reducing the manufacturing cost of the vehicle.

[0098] Please refer to Figure 8 , Figure 8 which is a schematic flowchart of a control method provided by an embodiment of the present application. This method can be applied to the central controller in the electrical system of a vehicle. The electrical system of the vehicle can include a central controller and electrical components, and there is a communication connection between the central controller and the electrical components.

[0099] As Figure 8 shown, the method can include the following steps:

[0100] S801. The electrical component sends the status information of the electrical component to the central controller.

[0101] Correspondingly, the central controller receives the status information of the electrical component.

[0102] Among them, the type of the electrical component can be referred to the foregoing and will not be elaborated here.

[0103] S802. The central controller generates a control instruction according to the status information.

[0104] Optionally, S803. The central controller sends the control instruction to the electrical component that sent the status information.

[0105] Correspondingly, the electrical component receives the control information sent by the central controller.

[0106] In a possible implementation manner, the number of electrical components is M, and the M electrical components can be divided into K electrical component groups. M is a positive integer, M>1, K is a positive integer, and K<M;

[0107] An electrical component group includes one or more electrical components, and the distance between any two electrical components in the electrical component group including multiple electrical components is less than a preset value.

[0108] Furthermore, each electrical component group is electrically connected to the first communication line through a second communication line.

[0109] Even further, 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.

[0110] It should be noted that dividing the M electrical components into K electrical component groups does not physically encapsulate the multiple electrical components into one electrical component group, but only regards multiple electrical components that meet the preset conditions as one electrical component group. In terms of the wiring structure, multiple electrical components in the same electrical component group can couple their respective corresponding second communication branch lines to the same second communication main line through the same interface. Furthermore, it can be understood that one electrical component group corresponds to one second communication main line. Based on the above content, it can be considered that one electrical component group is connected to the first communication line through one second communication main line, which helps to reduce the vehicle's demand for communication lines and / or power lines, thereby reducing the vehicle's manufacturing cost.

[0111] In a possible implementation manner, the method may further include:

[0112] If the first communication main line fails, any one of the first communication secondary lines between the central controller and the electrical component is turned on, and the central controller receives the electrical component through the first communication secondary line.

[0113] Among them, the first main communication line is the first communication line connected and conducting with the second communication line, and the first secondary communication line is the first communication line other than the first main communication line.

Among them, the memory 920 may be integrated in the processor 910 or may be separately provided from the processor 910.

[0118] The memory 920 may further include a storage system 921, a cache 922, and a RAM 923. Among them, the cache 922 is a primary memory existing between the RAM 923 and the CPU, composed of static storage chips (SRAM), with a relatively small capacity but much higher speed than the main memory, approaching the speed of the CPU; the RAM 923 is an internal memory that directly exchanges data with the CPU, can be read and written at any time (except during refreshing), and is very fast, usually used as a temporary data storage medium for the operating system or other running programs. The combination of the three realizes the function of the memory 920.

[0119] As an implementation manner, the function of the communication interface 930 can be considered to be implemented by a transceiver circuit or a dedicated transceiver chip.
