A control method and device

Abstract

This application provides a control method and apparatus. The method can be applied to a controller in a vehicle. The controller generates a message and sends the message to an electronic control unit (ECU). The message contains multiple bits and control information. The multiple bits can be used to indicate whether the ECU controls multiple objects (e.g., actuators or functions) based on the control information. Each bit corresponds one-to-one with one of the multiple objects, enabling the ECU associated with each object to control it based on the control information. This allows for the control of multiple objects within the vehicle while effectively reducing information redundancy in the vehicle's control messages and significantly improving the transmission efficiency of the control messages.

Description

Technical Field

[0001] This application relates to the field of vehicle networking technology, and in particular to a control method and device. Background Technology

[0002] With the continuous development of the automotive industry and the deepening of electrification, intelligence, connectivity, and sharing in automobiles, vehicle functions are becoming increasingly complex. To realize the functions of intelligent vehicles, controllers and electronic control units (ECUs) are installed. The controller can send control messages to the ECU, which can then control the actuators in the vehicle to perform corresponding functions based on these messages. Currently, communication between the controller and the ECU is mainly achieved through communication protocols such as Controller Area Network (CAN), Controller Area Network Flexible Data Rate (CAN FD), or Local Interconnect Network (LIN). These protocols use fixed-length encoding formats, and the content of the transmitted messages is fixed, as is the number and order of control signals within the messages.

[0003] As vehicle functions become increasingly sophisticated, the combinations of control signals in vehicle control messages become more complex, and frequent updates to some functions necessitate constant modifications to these control messages. Taking seat control functions as an example, if the aforementioned fixed-length encoding format is used to design control messages, even when only some motors or functions of the seat need to be controlled, the control message still needs to contain control information for all motors or all functions. This results in significant information redundancy, leading to wasted transmission bandwidth and low transmission efficiency. Furthermore, once vehicle functions are updated, extensive modifications to the control signals in the control message are required. Therefore, the aforementioned fixed-length encoding format is unsuitable for designing vehicle control messages with complex functions or frequent function upgrade requirements.

[0004] Therefore, how to flexibly design vehicle control messages, reduce information redundancy in control messages, thereby reducing communication resource overhead and improving the transmission efficiency of vehicle control messages is an urgent problem to be solved. Summary of the Invention

[0007] In this embodiment, the controller can control multiple objects of the vehicle by setting multiple bits in the message to indicate whether the electronic control unit controls multiple objects based on control information, and associating these multiple bits with multiple objects one by one. This effectively reduces information redundancy in the vehicle's control message, thereby effectively reducing communication resource overhead and effectively improving the transmission efficiency of the vehicle's control message.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described below with reference to the accompanying drawings.

[0077] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0078] 1) The object can be understood as the actuators or functions associated with the vehicle. Actuators can include chassis actuators, windows, doors, lights, or sensors, etc.; functions can include on-board equipment control functions, body component control functions, charging control functions, or sensor control functions, etc. On-board equipment control functions can be understood as the control functions of on-board equipment (e.g., seat control functions, car audio control functions, etc.); body component control functions can be understood as the control functions of body components (e.g., controlling door opening, controlling light activation, etc.); charging control functions can be understood as the control of related components in the vehicle's energy system (e.g., on-board charger (OBC), motor control unit (MCU) to achieve charging); sensor control functions can be understood as the control functions of sensors (e.g., controlling cameras or LiDAR to collect environmental image information around the vehicle).

[0079] 2) Control information can be understood as the information in the vehicle's control message used to control the vehicle's objects, also known as control signals.

[0080] 3) In the embodiments of this application, "at least one" refers to one or more, and "at least two" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can represent: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0081] 4) In this application's embodiments, the modifiers such as "first" and "second" are used to distinguish multiple modified contents, and are not used to limit the size, shape, content, order, timing, priority, quantity, or importance of the multiple modified contents. For example, "first information" and "second information" are only used to distinguish different information, and do not indicate different priorities or importance of the information. Furthermore, in this application's embodiments, the term "exemplary" is used to indicate that it is used as an example, illustration, or explanation. Any embodiment or design scheme described as "exemplary" in this application should not be construed as being better or more advantageous than other embodiments or design schemes. Specifically, the use of the term "exemplary" is intended to present the concept in a concrete manner.

[0082] This application provides a control method applicable to a controller in a vehicle. The controller generates a message and sends it to an electronic control unit (ECU). The message contains multiple bits and control information. These bits indicate whether the ECU controls multiple objects (actuators or functions) based on the control information. Each bit corresponds one-to-one with one of the objects, enabling the ECU to control multiple objects based on the control information. This effectively reduces information redundancy in the vehicle's control messages, thereby reducing communication resource overhead and improving the transmission efficiency of the control messages.

[0083] Before introducing the control method provided in the embodiments of this application, the system architecture applicable to the embodiments of this application will be described in detail first.

[0084] Figure 1 A schematic diagram of a traditional system architecture for implementing electronic control functions in automobiles is shown. Figure 1 The system 100 shown includes a Controller Area Network Calibration Protocol (CCP) 110, n domain controllers (DCs) 120, and m automotive components 130, where n and m are positive integers.

[0085] The CCP 110 communicates with n DCs, receiving data from the DCs or sending control information to them. The CCP 110 can be understood as a central platform for automotive electronic control and information processing. By optimizing and integrating the vehicle's distributed computing and control systems (e.g., ECUs or DCs), it achieves networked, integrated control and management of various functional modules related to vehicle computing, control, and communication, maximizing real-time sharing of automotive computing, control, and other hardware and software resources.

[0086] DC 120: Each DC 120 manages a specific functional domain within the vehicle, meaning that the DC has communication connections with multiple vehicle components located within that functional domain. The DC 120 is used to control the vehicle components within its corresponding functional domain, or to provide data processing capabilities for those components.

[0087] The aforementioned functional domains are typically divided based on the functions of automotive components. Each functional domain has an independent domain controller, or DC. Generally, the DC in a vehicle can include an autonomous driving domain controller, a cockpit domain controller (CDC), and a vehicle domain controller (VDC), among others.

[0088] The aforementioned autonomous driving domain controller provides services to automotive components in the intelligent driving domain, including monocular cameras, binocular cameras, millimeter-wave radar, lidar, and ultrasonic radar. It should be noted that the functionality of the aforementioned autonomous driving domain controller can be implemented by a mobile data center (MDC).

[0089] The aforementioned CDC is used to provide services for automotive components in the cockpit domain, which include head-up displays, instrument displays, radios, navigation systems, surround-view cameras, etc.

[0090] The aforementioned VDC is used to provide services for automotive components in both the body and chassis domains. Body domain components include window and door controllers, power mirrors, air conditioning, and central locking systems. Chassis domain components include components in the braking system, steering system, and accelerator pedal.

[0091] Automotive component 130 may specifically include ECU 131 and actuator 132. For example, it may be a sensor or actuator in the vehicle.

[0092] ECU 131, located inside automotive component 130, provides electronic control functions for automotive component 130. Examples include the electronic control unit inside a windshield wiper or an electronic control unit located inside a door.

[0093] In one possible implementation, DC120 can be used to generate a message and send it to ECU131 in automotive component 130. This message contains multiple bits and control information. The multiple bits can then be used to indicate whether ECU131 controls multiple objects (e.g., actuators or functions) based on the control information. Each bit corresponds one-to-one with one of the multiple objects, enabling the ECU associated with each object to control it based on the control information. This allows for the control of multiple objects within the vehicle while effectively reducing information redundancy in the vehicle's control messages and significantly improving the transmission efficiency of the vehicle's control messages.

[0094] It should be understood that the aforementioned "object" can be an actuator or a function. An actuator can be understood as a window, headlight, chassis actuator, energy system components, and sensor, etc. Energy system components can include an on-board charger (OBC), a motor control unit (MCU), etc.; sensors can include millimeter-wave radar, lidar, cameras, etc. A function can be understood as an on-board equipment control function, a body component control function, a charging control function, a sensor control function, etc. Specifically, an on-board equipment control function can be understood as the control function of on-board equipment (e.g., seat control, car audio control); a body component control function can be understood as the control function of body components (e.g., controlling door opening, controlling light activation); a charging control function can be understood as controlling relevant components of the vehicle's energy system (e.g., the on-board charger (OBC) and motor control unit (MCU) to achieve charging); a sensor control function can be understood as the control function of sensors (e.g., controlling a camera or lidar to collect environmental image information around the vehicle).

[0095] It should be noted that the electronic control unit in the embodiments of this application can be an electronic control unit inside multiple automotive components in the engine system, or it can be a centralized controller located outside multiple automotive components in the engine system for controlling multiple automotive components in the engine system. No specific limitations are made here.

[0096] For example, Figure 2 The diagram illustrates a scenario applicable to the embodiments of this application. Figure 2 In the example of DC, the cockpit domain controller is connected to multiple ECUs, and each ECU can be used to control multiple actuators.

[0097] The cockpit domain controller can generate a message and send it to the ECU. This message contains multiple bits and control information. These bits indicate whether the ECU should control multiple objects based on the control information. Each bit corresponds one-to-one with an actuator or function, allowing the ECU to control these multiple objects based on the control information.

[0098] The ECU can receive messages and control multiple objects based on the control information. It should be understood that in this embodiment, the objects can be actuators or functions. Actuators can be understood as windows, lights, chassis actuators, energy system components, and sensors. Energy system components include on-board chargers (OBC), motor control units (MCUs), etc.; sensors can include millimeter-wave radar, lidar cameras, etc. The functions can be understood as on-board equipment control functions, body component control functions, charging control functions, sensor control functions, etc. Among them, the vehicle equipment control function can be understood as the control function of vehicle equipment (e.g., the control function of seats, the control function of car audio, etc.); the body component control function can be understood as the control function of body components (e.g., controlling the opening of doors, controlling the turning on of lights, etc.); the charging control function can be understood as the control of related components of the energy system in the vehicle (e.g., the on-board charger (OBC) and the motor control unit (MCU) to realize the charging function); the sensor control function can be understood as the control function of sensors (e.g., controlling cameras or lidar to collect environmental image information around the vehicle).

[0099] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0100] The above describes the applicable scenarios and architectures of the embodiments of this application. The control methods provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0101] Please see Figure 3 , Figure 3 This is a flowchart illustrating a control method provided in an embodiment of this application. This method can be applied to... Figure 2 In the scenario shown, the method includes the following steps:

[0102] S301: The controller generates a message.

[0103] The message contains multiple bits and control information. These multiple bits can be used to indicate whether the electronic control unit associated with the controller controls multiple objects based on the control information, and there is a one-to-one correspondence between the multiple bits and the multiple objects. For example, if the message needs to control 16 objects, then the message includes 16 bits.

[0104] It should be understood that in the embodiments of this application, the controller can be any one of the following: body domain controller, cockpit domain controller, intelligent driving domain controller, vehicle control domain controller, and vehicle controller. The embodiments of this application do not impose specific limitations. In the embodiments of this application, the "object" can be an actuator or a function. An actuator can be understood as a window, headlight, chassis actuator, energy system component, and sensor. Energy system components include on-board chargers (OBC), motor control units (MCUs), etc.; sensors can include millimeter-wave radar, lidar, cameras, etc. The function can be understood as an on-board equipment control function, a body component control function, a charging control function, a sensor control function, etc. Specifically, an on-board equipment control function can be understood as a control function for on-board equipment (e.g., seat control function, car audio control function, etc.); a body component control function can be understood as a control function for body components (e.g., controlling door opening, controlling headlights, etc.); and a charging control function can be understood as controlling related components of the energy system in the vehicle (e.g., on-board chargers (OBC), motor control units (MCUs), etc.). The electronic control unit (MCU) implements the charging function; the sensor control function can be understood as the control function of sensors (e.g., controlling a camera or lidar to collect environmental image information around the vehicle). It should be noted that the multiple bits in the above message may include valid bits and / or invalid bits. For example, a valid bit can be represented by "1", and an invalid bit can be represented by "0". Valid bits are used to instruct the electronic control unit to control the first object among multiple objects based on the control information, while invalid bits are used to instruct the electronic control unit not to control the second object among multiple objects based on the control information. It should be understood that the number of valid bits can be one or more, and one valid bit corresponds to one first object; the number of invalid bits can be zero or one or more, and one invalid bit corresponds to one second object. The following is a detailed discussion of different cases.

[0105] Case 1: The above message contains only valid bits among its multiple bit positions.

[0106] For example, as shown in Table 1, the effective bits are represented by "1". Table 1 includes only 16 effective bits, so the electronic control unit can control the 16 first objects indicated by these 16 bits.

[0107] Table 1

[0108] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

[0109] Case 2: The above message contains both valid and invalid bits.

[0110] For example, as shown in Table 2, valid bits are represented by "1" and invalid bits are represented by "0". Table 2 includes 14 valid bits and 2 invalid bits. The electronic control unit can control the 14 first objects indicated by these 14 bits, but does not control the second objects indicated by these 2 invalid bits.

[0111] Table 2

[0112] 1 1 1 1 1 1 0 1 1 1 0 1 1 1 1 1

[0113] As another example, as shown in Table 3, valid bits are represented by "1" and invalid bits are represented by "0". Table 3 includes 15 valid bits and 1 invalid bit. The electronic control unit can control the 14 first objects indicated by these 15 bits, but does not control the second object indicated by this 1 invalid bit.

[0114] Table 3

[0115] 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1

[0116] In this way, by setting valid and invalid bits in multiple valid bits of the message, the electronic control unit can control the relevant objects (i.e., functions or actuators) of the vehicle according to the user's needs, effectively meeting the user's needs, while reducing information redundancy in the message.

[0117] In one possible implementation, the message also includes information indicating multiple objects. The information indicating multiple objects differs depending on whether the object is an executor or a function; this will be explained in detail below for specific situations.

[0118] Scenario 1: When the object controlled by the message is an actuator, the information used to indicate multiple objects may include identifiers of multiple actuators and identifiers of the first function. As shown in Table 4, taking the door opening function as an example, the first function may include an identifier of the door opening function and identifiers of multiple door numbers.

[0119] Table 4

[0120] The first function identifier Actuator Identifier Door opening function indicator Door 1 sign, Door 2 sign, Door 3 sign

[0121] Scenario 2: When the object controlled by the message is a function, the information used to indicate multiple objects may include identifiers of multiple functions and the identifier of the first actuator. As shown in Table 5, taking seat number 1 as an example, the message may include the number identifier of seat number 1, the heating function identifier, the cooling function identifier, and the adjustment function identifier.

[0122] Table 5

[0123] Identification of the first actuator Functional identifier Seat No. 1 number label Heating function label, cooling function label, adjustment function label

[0124] It should be noted that the above-mentioned controller can generate messages in various ways, including but not limited to the following:

[0125] Method 1: The controller can determine multiple objects and control information based on user input, and then generate a message based on the identification information of the multiple objects and the control information. The user input can be voice commands, key presses, or text commands, etc., and this embodiment does not impose specific limitations.

[0126] In one possible implementation, the controller can obtain user input through a human-machine interface system in the vehicle, which can be used to provide audio and video communication between the vehicle and the user, obtain user input, and transmit the user input to the controller.

[0127] For example, if the human-computer interaction system receives a user input as a voice command "heat all seats", and transmits the voice command to the controller, the controller will determine that the object to be controlled is the heating device of all seats in the vehicle. The control information corresponding to this object is, for example, the target temperature to be heated by the heating device.

[0128] For example, if the human-computer interaction system receives a user input as a voice command "adjust the backrest of the passenger seat", and transmits this voice command to the controller, the controller will determine the object to be controlled based on the voice command, which is motor number 1 of the two motors of the passenger seat. The corresponding control information for this object is, for example, the target speed of motor number 1.

[0129] In Method 1, the controller can generate vehicle control messages based on user input, thus making the control of relevant objects in the vehicle more in line with user needs.

[0130] Method 2: The controller can automatically generate messages based on the vehicle user's usage information.

[0131] For example, if the controller analyzes the vehicle user's usage information and finds that the user often turns on the car speakers to play music when starting to use the car, the controller will automatically generate a message to control the car speakers to turn on the next time it detects that the user has started using the car.

[0132] For example, if the controller analyzes the vehicle user's usage information and finds that the user does not use the vehicle between 2 pm and 4 pm, the controller will automatically generate a message to control the vehicle to enable the charging function during that time period.

[0133] In Method 2, the controller analyzes the user's vehicle usage information and automatically generates vehicle control messages, thus effectively realizing intelligent control of the vehicle, improving the vehicle's intelligence level, and thereby effectively enhancing the user experience.

[0134] S302: The controller sends this message to the electronic control unit, and the electronic control unit receives the message.

[0135] In one possible implementation, the controller can transmit the message via short-range wireless communication (e.g., green tooth) or via Ethernet bus; this application does not impose any specific limitations.

[0136] S303: The electronic control unit controls multiple objects based on this message.

[0137] In the first scenario, when the object is an actuator, the electronic control unit controlling multiple objects can be understood as controlling multiple actuators to achieve the first function.

[0138] For example, the actuator is a seat, and its primary function is seat adjustment. The electronic control unit can control all or some of the seats to be adjusted according to the message.

[0139] For example, if the actuator is a car window or a car light, and its primary function is to open, the electronic control unit can control the opening of the car windows and car lights in the vehicle according to the message.

[0140] For example, if the actuator is a sensor and its primary function is information acquisition, the electronic control unit can control multiple sensors to acquire information based on the message.

[0141] In the second scenario, when the object is a function, the electronic control unit controlling multiple objects can be understood as controlling multiple functions of the first actuator.

[0142] For example, the first actuator is seat number 1, which has functions such as heating, adjustment, and opening. The electronic control unit can control seat number 1 to perform one or more of the functions such as heating, adjustment, and opening according to the message.

[0143] For example, the first actuator is motor No. 1, which has the function of adjusting direction and speed. The electronic control unit can control the adjustment direction and speed of motor No. 1 according to the message.

[0144] The structure of the message provided in the embodiments of this application is described below with reference to the specific accompanying drawings.

[0145] For example, please see Figure 4A When the object controlled by the above message is an actuator, the message can be... Figure 4A The message 1 shown includes a function identifier field (vehicle func type(T)), a length field (vehicle funclength(L / 16bit)), an actuator identifier field, and a control information field.

[0146] The function identifier field corresponds to the first function identifier, which is used to identify the first function controlled by message 1.

[0147] The length field corresponds to the length of message 1 and is used to identify the bit length of message 1.

[0148] The actuator identifier field corresponds to multiple bits, with each bit used to identify an actuator.

[0149] Please continue reading Figure 4A , Figure 4A In the message 1, taking 16 bits as an example, these 16 bits are set in the actuator identification field, and the 16 bits include 4 valid bits and 12 invalid bits. Then message 1 can be used to control 4 actuators to achieve the first function.

[0150] The control information field corresponds to multiple control information entries, each of which corresponds to an actuator identified by a valid bit, and is used to control the actuator identified by that valid bit. Figure 4A If the message contains 4 valid bits, then message 1 includes 4 control information bits. For example, when the actuators are door 1, door 2, window 1, and window 2, message 1 may include control information 1 for controlling door 1 to open, control information 2 for controlling door 2 to open, control information 3 for controlling window 1 to open, and control information 4 for controlling window 2 to open.

[0151] For example, please see Figure 4B When the object controlled by the above message is a function, the message can be... Figure 4BThe message 2 shown in the message 1 includes a function identifier field (vehicle func type(T)), a length field (vehicle funclength(L / 16bit)), an actuator identifier field, and a control information field.

[0152] The function identifier field corresponds to multiple bits, with each bit used to identify a function.

[0153] Please continue reading Figure 4B , Figure 4B Taking 16 bits as an example, multiple bits of message 2 are set in the function identifier field. These 16 bits include 2 valid bits and 14 invalid bits. Message 2 can be used to control two functions of the first actuator.

[0154] The length field corresponds to the length of message 2 and is used to identify the bit length of message 2.

[0155] The actuator identifier field corresponds to the first actuator identifier, which is used to identify the first actuator controlled by message 1.

[0156] The control information field corresponds to multiple control information entries, each of which corresponds to a valid bit identifier function used to control the function of that valid bit identifier. Figure 4B If message 2 contains two valid bits, then message 2 can correspond to two control messages. For example, taking seat number 1 as an example, message 2 can include control information 1 for controlling the adjustment function of seat number 1 and control information 2 for controlling the heating function of seat number 1.

[0157] To facilitate understanding, the messages provided in the embodiments of this application are described below with specific examples.

[0158] Example 1, please see Figure 5A ,exist Figure 5AIn this message, message 3 controls actuators, specifically seats. Message 3 controls the heating functions of seats 1, 2, 7, and 16. The function identifier field of message 3 is the seat heating function identifier (0001). The actuator identifier field includes the seat number identifiers (10000001) and 16 bits corresponding to seats 1-16, with only 4 valid bits (bits marked "1"). The control information field of message 3 includes control information 1, control information 2, control information 3, and control information 4. Control information 1 controls the temperature of seat 1 to 25 degrees Celsius; control information 2 controls the temperature of seat 2 to 25 degrees Celsius; control information 3 controls the temperature of seat 7 to 25 degrees Celsius; and control information 4 controls the temperature of seat 16 to 25 degrees Celsius.

[0159] Example 2, please see Figure 5B ,exist Figure 5B In message 4, the object to be controlled is a function. Message 4 is used to control the heating and adjustment functions of seat number 1 in the vehicle. The function identification field of message 3 includes a heating function identifier (0001) and an adjustment function identifier (0002), as well as 16 bits for identifying 16 functions of the seat. Only two of these 16 bits are valid (i.e., bits marked "1"). These two valid bits are used to identify the adjustment and heating functions of the seat, respectively. The actuator identification field in message 4 includes the number identifier of seat number 1 (000001). The control information field of message 4 includes control information 1 and control information 2. Control information 1 can be used to control the temperature adjustment of seat number 1 to 25 degrees Celsius, and control information 2 can control the adjustment of seat number 1 to an extended state. It should be understood that control information 2 may also include hierarchical control information for the adjustment function, such as control information for adjustment speed and adjustment direction, etc., which are not specifically limited in this embodiment.

[0160] In the above embodiments, the controller can control multiple objects of the vehicle by setting multiple bits in the message to indicate whether the electronic control unit controls multiple objects based on control information, and by associating multiple bits with multiple objects one by one. This can effectively reduce information redundancy in the vehicle's control message, thereby effectively reducing communication resource overhead and effectively improving the transmission efficiency of the vehicle's control message.

[0161] In some possible embodiments, the message may further include a synchronization bit. In this case, the control information in the message can be a single control message; that is, only one control message needs to be set in the message. The synchronization bit can be used to instruct the electronic control unit to control multiple objects based on a single control message. The value of the synchronization bit can be 0 or 1. When the synchronization bit is 1, the electronic control unit can control multiple objects based on a single control message; when the synchronization bit is 0, the electronic control unit cannot control multiple objects based on a single control message. This further optimizes the message structure and reduces information redundancy in the message.

[0162] Example 1, please see Figure 6A , Figure 6A The object controlled by message 5 is an actuator. The function identifier field in message 5 is the first function identifier, the length field is 65 bits, the synchronization bit in message 5 is "1", the actuator identifier field in message 5 includes 16 bits, of which 7 are valid bits, and the control information field includes control information 1. Therefore, message 5 can control the actuator corresponding to these 7 valid bits based on control information 1 to achieve the first function. For example... Figure 6B As shown, taking the seat as an example, the first function is the adjustment function. After receiving message 5, the electronic control unit can control the seven seats in the vehicle to achieve the adjustment function based on the control information 1 in message 5.

[0163] Example 2, please see Figure 6C The message shown, Figure 6C The object controlled by message 6 is an actuator. The function identifier field in message 6 consists of 16 bits, including 2 valid bits. The length field in message 6 is 65 bits, the synchronization bit is set to "1", the actuator identifier field is the first actuator identifier, and the control information field includes control information 1. Therefore, message 6 can control the actuator corresponding to these 7 valid bits based on control information 1 to achieve the first function. For example... Figure 6D As shown, taking seat number 1 as an example, and its functions as adjustment and heating, the electronic control unit, after receiving message 6, can control seat number 1 to perform the adjustment and heating functions based on control information 1 in message 6. For example... Figure 6E As shown, when the synchronization bit is "0", the control information corresponding to the heating function and the adjustment function are different. The control information field of this message carries control information 1 for controlling seat No. 1 to reach the target temperature, and control information 2 for controlling seat No. 1 to be adjusted to the folding state.

[0164] In this embodiment, by setting a synchronization bit in the message, the vehicle control message only needs to carry one control message to control multiple actuators or functions. This reduces data redundancy in the message, thereby significantly reducing data overhead.
