Description

Technical Field

[0001] The present invention relates to the technical field of network management, and in particular to a vehicle network management method, device, equipment and storage medium. Background Art

[0002] At present, as cars become more and more intelligent, the number of electronic controllers carried by cars continues to increase, and the overall power consumption increases, which has a huge impact on the car's cruising range. In related technologies, a network structure is mainly used to connect all electronic controllers in the car, and communicate through the CAN (Controller Area Network) bus, so as to manage the network segments in the vehicle and solve the problem of car energy saving. Network management can make the electronic controllers sleep and wake up in an orderly manner through the network, that is, each network segment sleeps when there is no communication demand and wakes up when communication is required.

[0003] However, when faced with the increasing number of network segments in automobiles, traditional network management, on the one hand, cannot dynamically configure the network management type of each network segment and the number of network segments of the corresponding network management type for different vehicle models to adapt to different bus configurations; on the other hand, the network segments cannot be collaboratively managed for sleep and wake-up, resulting in asynchronous network status switching of each network segment and low reliability and stability of network management. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a vehicle network management method, device, equipment and storage medium to solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of an embodiment of the present invention, there is provided a vehicle network management method, comprising:

[0006] Obtain a vehicle bus in a target vehicle, and configure the number and type of network segments according to the vehicle bus;

[0022] When the second network management segment maintains the sleep waiting state for a preset second sleep time, the second network management segment is switched to the sleep state, and communication with the non-network management segment is stopped, and the network also includes the non-network management segment.

[0023] In one embodiment of the present invention, if the network segment is in the sleep state and satisfies at least one of the awakening conditions, all network segments of the target vehicle are awakened, including:

[0024] When the first network management network segment is in the pre-sleep state or the sleep state, waking up the network segment based on the wake-up condition;

[0025] When the second network management network segment is in the sleep waiting state or the sleep state, waking up the network segment based on the wake-up condition;

[0028] If the network segment detects that a local wake-up event occurs, the local wake-up condition is met, the current network segment is woken up, and the remaining network segments are woken up through the current network segment.

[0051] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0053] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0054] Figure 1 is a flow chart of a vehicle network management method according to an exemplary embodiment of the present invention.

[0055] Reference Figure 1 As shown, in an exemplary embodiment, the vehicle network management method includes at least steps S110 to S150, which are described in detail as follows:

[0056] Step S110, obtaining a vehicle bus in the target vehicle, and configuring the number and type of network segments according to the vehicle bus.

[0057] It should be understood that different vehicle models are configured with different vehicle buses. First, the type and quantity of the vehicle bus are determined based on the configuration of the target vehicle, and then the type and quantity of the vehicle bus are converted into the corresponding network structure to configure the type and quantity of the network segments in the target vehicle. The types of network segments include the first network management segment of the automotive open system architecture, the second network management segment of the automotive electronics open system, and the non-network management segment.

[0058] Figure 2 It is a schematic diagram of a network topology state shown in an exemplary embodiment of the present invention.

[0059] Reference Figure 2 As shown, in one embodiment of the present invention, the network topology of the target vehicle can be Figure 2The bus network topology structure in the whole network includes eight network segments, including DCAN (i.e., diagnostic controller area network), ADASCAN (i.e., driving controller area network), DATACAN (i.e., data controller area network), INFOCAN (i.e., information controller area network), BCAN (i.e., body controller area network), PTCAN (i.e., power controller area network), HEVCAN (i.e., new energy controller area network) and EPSCAN (i.e., steering controller area network). These network segments can be divided into three types according to the different network management methods, including AUTOSAR (AUTomotive Open System Architecure, automotive open system architecture) network management segment, OSEK (i.e., German automotive electronics open system and corresponding interface standard) network management segment and no network management. Among them, in the present invention, the first network management segment can be an AUTOSAR network management segment, and the second network management segment can be an OSEK network management segment. Figure 2 As shown, the number of first network management segments is three, the number of second network management segments is two, and the number of non-network management segments is three. Among them, the first network management segment can be customized and can be configured as a type of sometimes first network management, and can also be configured as a type of no network management. It should be noted that the present invention does not limit the number of segments in the target vehicle, and the type of segments and the number of segments corresponding to different types support dynamic configuration.

[0060] Step S420, monitoring the network status of each network segment to determine whether the network segment meets the sleep condition or the wake-up condition.

[0061] In one embodiment of the present invention, the network status of each network segment needs to be monitored. If the network segment is communicating normally, then it is determined whether the network segment meets the sleep condition; if the network segment is in a sleep state, then it is determined whether the network segment meets the wake-up condition.

[0062] In one embodiment of the present invention, a network segment will be awakened if it meets any one of the awakening conditions. Figure 2 The wake-up conditions of the configured network segment are shown in Table 1:

[0063] Table 1

[0064]

[0065] From Table 1, we can see that Figure 2 The network segment in can be awakened if it meets any of the awakening conditions in Table 1.

[0066] Step S130: If the network segment meets the sleep condition, the network state of the network segment is switched to the sleep state.

[0067] It should be understood that the network state of the network segment can be switched to the sleep state through steps S131 to S133.

[0068] Step S131, determining whether the network segment meets the sleep condition.

[0069] In one embodiment of the invention, before determining whether a network segment meets the sleep condition, it is necessary to determine the type of network segment. If the network segment is a second network management segment, it is necessary to determine whether the network segment meets the sleep condition based on the local sleep event; if the network segment is a first network management segment, it is necessary to first determine whether the first network management segment is a multi-network management segment or a single network management segment, and the basis for the determination is the number of first network management segments in the target vehicle. When the network segment is a multi-network management segment, it is determined whether the network segment meets the sleep condition based on the local sleep event and the first network message received, that is, the first network message is used as a local sleep event. Among them, the first network message involved in the judgment is received by the network segment within the preset clearing time, and the first network message received by the network segment outside the preset clearing time may be cleared; when the network segment is a single network management, the sleep condition that needs to be met is the same as that of the second network management segment.

[0070] In one embodiment of the present invention, only when all the sleep conditions are met at the same time, can each network segment in the target vehicle be controlled to enter sleep mode, and it can be accurately determined whether the current network segment needs to be switched to sleep mode. Figure 2 The sleep conditions of the configured network segment are shown in Table 2:

[0071] Table 2

[0072]

[0073] It should be noted that all the sleep conditions in Table 2 are in a relationship of and , and all must be met to switch the network segment to the sleep state. The time involved in the sleep conditions can be set according to actual needs.

[0074] In one embodiment of the present invention, before determining whether the first network segment is a multi-network management segment or a single network management segment, the validity of the first network message received by the current first network management segment is periodically determined. It should be noted that the determination period can be configured according to actual conditions.

[0075] Step S132: after the network segment meets the sleep condition, the network state of the network segment is switched to the pre-sleep state.

[0076] In one embodiment of the present invention, to switch the network state of a network segment to a sleep state, it is necessary to first switch the network segment to a pre-sleep state. When the network segment is a first network management segment, after the sleep condition is met, the network segment will switch to a sleep-ready state and stop forwarding the first network message until the network segment does not continue to receive the first network management message within a preset timeout period, at which time the network segment is switched from a sleep-ready state to a pre-sleep state and stops sending application messages. When the network segment is a second network management message, after the sleep condition is met, a node in the network segment will generate a pre-sleep query instruction, send it to the remaining nodes in the network segment, and switch the network state of the network segment to a pre-sleep state.

[0077] Step S133, switching the network segment from the pre-sleep state to the sleep state.

[0078] In one embodiment of the present invention, when the network segment is a first network management network segment, if the time that the network segment is in the pre-sleep state reaches the preset first sleep time, the network segment is switched from the pre-sleep state to the sleep state. When the network segment is a second network management network segment, the node in the network segment that receives the pre-sleep query instruction will respond to the pre-sleep query instruction and send a response message to the node of the pre-sleep query instruction. If the response message meets the preset conditions, for example, the response message is to allow sleep, the network segment is switched from the pre-sleep state to the sleep waiting state until the time that the network segment is in the sleep waiting state reaches the preset second sleep time, the network segment is switched from the sleep waiting state to the sleep state, and the network segment without network management is prevented from continuing to communicate. It should be noted that the preset first sleep time and the preset second sleep time can be the same or different, and can be adjusted according to actual conditions. For example, if the real-time requirement for the target vehicle to switch to the sleep state is high, the preset first sleep time and the preset second sleep time are set to a smaller value.

[0079] In one embodiment of the present invention, if the network segment switches to sleep mode, the bus in the target vehicle is switched to edge detection mode, so that the target vehicle can be awakened by external interruption when all network segments enter sleep mode and the target vehicle is in low power consumption.

[0080] Figure 3 The figure is a flowchart showing vehicle network management sleep according to an exemplary embodiment of the present invention.

[0081] Reference Figure 3In one embodiment of the present invention, the process of switching the network state of a network segment to a sleep state includes five parts. In the first part, taking the first network management network segment as an example, first determine whether the first network management network segment receives a valid first network management message, and then determine whether the first network management network segment is a multi-network management network segment or a single network management network segment. There is a difference between the multi-network management network segment and the single network management network segment in determining whether the sleep condition is met. Among them, the single network management network segment only needs to make a judgment based on the local wake-up event, and the first network management message received by the first network management network segment in the multi-network management network segment within the preset clearing time will also participate in the judgment. In the second part, after the sleep condition is met, the first network state will be switched to the ready sleep state, stop forwarding the first network management message, and then determine whether the preset timeout time is reached. If not, continue to wait. In the third part, when the first network management network segment still does not receive the first network management message after the preset timeout time, the first network management network segment is switched to the pre-sleep state and the application message is stopped forwarding; at the same time, the network state of the second network management network segment is switched to the pre-sleep state, and the second network management network segment meets the sleep condition. In the fourth part, if the first network management segment maintains the pre-sleep state for the preset first sleep time, the first network management segment is switched to the sleep state, and the vehicle bus is switched to the edge detection mode. In the fifth part, if the node that sends the sleep query request in the second network management segment receives the response information of the remaining nodes, and the message meets the preset conditions, the second network management segment is switched to the sleep waiting state until the preset second sleep time is reached, the second network management segment is switched to the sleep state, and the communication without network management is stopped, and the vehicle bus is switched to the edge detection mode.

[0082] Figure 4 It is a schematic diagram showing a first network management segment switching network state according to an exemplary embodiment of the present invention.

[0083] Reference Figure 4 As shown, the network status of the first network management segment includes normal operation status, sleep preparation status, pre-sleep status, sleep status and repeated message status, wherein the normal operation status refers to when the first network management segment is communicating. The repeated message status includes a normal sending sub-state and a fast sending sub-state. Figure 4The network message in is equivalent to the first network message, the network message receiving timeout is equivalent to the above-mentioned preset timeout period for receiving the first network message, and the waiting sleep timeout period is equivalent to the above-mentioned preset first sleep time. In the repeated message state, the current first network management segment will continue to periodically send the first network message to prompt the other segments of the first network management terminal to enter the normal operating state or the sleep preparation state. Among them, in the normal sending sub-state, the first network management segment must send the first network message at a normal period; in the fast sending sub-state, the first network management segment must send the first network management message at a fast period. Figure 4 The network status switching process of the first network management segment shown has been described in the above embodiment and will not be repeated here.

[0084] Figure 5 It is a schematic diagram showing a second network management segment switching network state according to an exemplary embodiment of the present invention.

[0085] Reference Figure 5 As shown, the network status of the second network management segment includes normal operation status, pre-sleep status, normal waiting sleep status and sleep status, wherein the normal operation status refers to when the second network management segment is communicating, the normal waiting sleep status is equivalent to the above-mentioned sleep waiting status, and after the second network management segment wakes up, it will perform network initialization operations on it. Figure 5 The network status switching process of the second network management segment shown has been described in the above embodiment and will not be repeated here.

[0086] Step S140: If the network segment is in a sleeping state and satisfies at least one awakening condition, all network segments of the target vehicle are awakened.

[0087] In one embodiment of the present invention, the wake-up condition includes a local wake-up condition and a remote wake-up condition, wherein the local wake-up condition refers to the detection of the occurrence of a local wake-up event, such as the wake-up condition for detecting vehicle bus activity in Table 1; the remote wake-up condition refers to the detection of a second network management message, such as the wake-up condition for detecting the second network management message in Table 1. It should be noted that the second network management message is valid only if it carries a wake-up flag. When the network segment is a first network management network segment, the network segment can only be awakened when it is in a pre-sleep state or a sleep state; when the network segment is a second network management network segment, the network segment can only be awakened when it is in a sleep preparation state or a sleep state. When the current network segment is awakened, the second network message will be sent to the remaining network segments, thereby awakening all network segments of the target vehicle.

[0088] Figure 6 It is a block diagram of a vehicle network management device shown in an exemplary embodiment of the present invention.

[0089] Reference Figure 6 As shown, the exemplary vehicle network management device includes: a configuration module 601 , a monitoring module 602 , a sleeping module 603 and a wake-up module 604 .
