Referring to fig. 1, fig. 1 illustrates a method for determining a sleep wakeup abnormality according to an embodiment of the present application, and in a specific embodiment, the method for determining a sleep wakeup abnormality may be applied to a device 500 for determining a sleep wakeup abnormality and an electronic device 600 (fig. 6) configured with the device 600 for determining a sleep wakeup abnormality as illustrated in fig. 5. The specific flow of the present embodiment will be described below, and it will be understood that the method may be performed by an electronic device having computing processing capability, such as a server, a cloud server, etc., which is not specifically limited herein. The method for determining the sleep wakeup abnormality specifically may include the following steps:
Step 110, if it is determined that the usage mode of the vehicle is the standby mode, detecting whether an unsecured network exists in the network of the vehicle.
As one way, the usage mode of the vehicle may refer to a mode corresponding to a current state of the vehicle or a current gear of the vehicle. Alternatively, the usage mode of the vehicle may be a driving mode when the vehicle is in a running state or the gear of the vehicle is ON or START; the usage mode of the vehicle may be a sleep mode when the vehicle is in a stopped state or the gear of the vehicle is in an "OFF" or "LOCK" gear; the usage mode of the vehicle may be a comfort mode when the gear of the vehicle is in the "ACC" gear; when the vehicle is in the "ON" gear but is simultaneously in the "P" gear or the parking brake of the vehicle is in a braking state, the usage mode of the vehicle may be a standby mode, and the classification of the specific usage modes of the vehicle may be set according to actual needs, which is only exemplified herein and not particularly limited.
Alternatively, when the usage mode of the vehicle is the standby mode, it may be determined that the network of the vehicle is dormant, and at this time, in order to determine whether there is a dormant abnormality in the network of the vehicle, it is necessary to determine whether there is an un-dormant network in the standby mode.
As one way, when it is determined that the usage mode of the vehicle is the sleep mode, it may be detected whether there is an unset network among the networks of the vehicle after a preset period of time. Optionally, the preset duration may be a duration that the usage mode of the vehicle changes from the standby mode to the sleep mode, or may be a duration that all networks in the vehicle complete sleep in the standby mode, and the preset duration may be set according to actual needs, which is not specifically limited herein.
As one approach, the detection of each network in the vehicle may be performed by a gateway or central processor in the vehicle. Optionally, the gateway or the central processor may periodically detect the network in the vehicle, so as to improve the accuracy of sleep anomaly detection of the network of the vehicle. Alternatively, the gateway or the central processor may detect through a network message reported by the network of the vehicle, or may detect through other means.
Step 120, if it is detected that the non-dormant network exists, acquiring network information of the non-dormant network, where the network information of the non-dormant network includes a node address of the non-dormant network, wake-up information of the non-dormant network, and maintenance information of the non-dormant network.
As one way, whether the corresponding network is in a dormant state may be determined by whether a network message of an unsecured network is received, thereby determining whether an unsecured network exists in the network of the vehicle. Optionally, when the network of the vehicle is in a dormant state, the network of the vehicle and the gateway of the vehicle and the central processing unit of the vehicle do not perform information interaction, i.e. the network of the vehicle does not send a corresponding network message to the gateway or the central processing unit.
As another way, the vehicle may include a plurality of networks, where each network may include a plurality of nodes, and functions corresponding to each node are different, and when a function corresponding to any one node in a network is in an on state, it may be determined that the network corresponding to the any one node is in an un-dormant state, that is, the un-dormant network may be determined according to the network corresponding to the function in the on state in the vehicle.
As one way, when the existence of the non-dormant network is detected, network information of the non-dormant network may be determined through a network message transmitted by the non-dormant network. Optionally, the node address of the non-dormant network may be included in the network message of the non-dormant network, and then the corresponding wake-up information and the maintenance information are determined based on the node address. Optionally, a mapping relationship between the node address of each network in the vehicle and the corresponding wake-up information and maintenance information may be predetermined, and after determining the node address of the non-dormant network, the wake-up information and maintenance information of the non-dormant network may be determined based on the mapping relationship, so as to obtain the network information of the non-dormant network.
The wake-up information of the non-dormant network is a reason for each wake-up of the network, and the maintenance information of the non-dormant network is a reason for maintaining the network to keep the wake-up. Alternatively, the wake-up reasons for an un-dormant network may include passive wake-up reasons and active wake-up reasons for the network. Alternatively, there is and only one wake-up reason for each wake-up of the network in the vehicle.
And 130, if the duration of the non-dormant network in the non-dormant state is determined to be longer than a duration threshold, determining a dormant abnormal node according to the node address of the non-dormant network, and determining the dormant abnormal reason of the dormant abnormal node according to the awakening information of the non-dormant network and the maintaining information of the non-dormant network.
As one way, since the network in the vehicle will go to sleep only after not being awakened for a period of time in the standby mode, and a certain delay period is required for the corresponding sleep, a period threshold is set, after the period threshold, the non-sleep network is still in the non-sleep state, and it can be determined that the non-sleep network is in the abnormal sleep condition.
As one way, the vehicle may include a plurality of networks, where each network may include a plurality of nodes, and when all nodes under a network are dormant, the corresponding network is in a dormant state, and if any node is in an unsecured state, it may be determined that the network is in an unsecured state, that is, the network is an unsecured network. It may be understood that, in order to determine the cause of the dormancy abnormality of the non-dormant network, the corresponding dormant abnormal node needs to be determined according to the node address of the non-dormant network, and then the cause of the dormancy abnormality of the dormant abnormal node is determined based on the wake-up information and the maintenance information of the non-dormant network, so as to determine the cause of the non-dormancy of the non-dormant network. Optionally, the wake-up information of the non-dormant network and the maintenance information of the non-dormant network include a wake-up source and a maintenance source of each node in the non-dormant network.
In some embodiments, after step 130, the method for determining a sleep wakeup exception further includes: and acquiring node information of the sleep abnormal node, and transmitting the node information of the sleep abnormal node to a gateway of the vehicle so that the gateway records the sleep abnormal node, wherein the node information of the sleep abnormal node comprises a node address of the sleep abnormal node and the sleep abnormal reason.
As one mode, each network in the vehicle interacts with the bus network, after determining the reason of the sleep abnormality node, the bus network receives a network message sent by the non-sleep network, determines the node address and the reason of the sleep abnormality node in the sleep abnormality in the network message, packages the network message to obtain the node information of the sleep abnormality node, then sends the node information of the sleep abnormality node to the gateway, and the gateway records the sleep abnormality node after receiving the node information of the sleep abnormality node.
Optionally, after receiving the node information of the dormant abnormal node, the gateway records the node information of the dormant abnormal node in a local database of the vehicle, so that a driver can check and overhaul conveniently; the gateway can also upload the node information of the dormant abnormal node to the cloud server, so that a vehicle developer can optimally upgrade the vehicle based on the node information of the dormant abnormal node; the gateway can also send the node information of the dormant abnormal node to the electronic equipment in communication connection with the vehicle, and the electronic equipment prompts the user after receiving the node information so that the user can process in real time.
In the embodiment of the application, after the non-dormant network is detected in the standby mode of the vehicle, the node address, the awakening information and the maintenance information of the non-dormant network are acquired, and when the non-dormant network is determined to be dormant according to whether the duration of the non-dormant state of the non-dormant network is greater than the threshold value, the dormant abnormal node and the dormant abnormal information of the dormant abnormal node can be determined according to the node address, the awakening information and the maintenance information of the non-dormant network, so that the dormant abnormal network and the dormant abnormal cause can be rapidly positioned, the vehicle can improve the dormant abnormal determination efficiency of the vehicle, and the difficulty of the dormant abnormal determination can be reduced.
Referring to fig. 2, fig. 2 illustrates a method for determining sleep wakeup anomalies according to an embodiment of the present application. The method for determining the sleep wakeup abnormality specifically may include the following steps:
If it is determined that the usage mode of the vehicle is the standby mode, step 210 is performed, whether an unsecured network exists in the network of the vehicle is detected.
The specific step description of step 210 may refer to the specific step description of step 110, and will not be described herein.
Step 220, if it is detected that the non-dormant network does not exist, detecting whether a awakened network exists in the network of the vehicle.
As one way, whether the corresponding network is in a dormant state may be determined by whether a network message of an un-dormant network is received, thereby determining whether a awakened network exists in the network of the vehicle.
Alternatively, when the usage mode of the vehicle is the sleep mode, whether the non-sleep network exists in the vehicle may be periodically detected, so as to detect whether the awakened network exists.
As a further mode, the vehicle may include a plurality of networks, where each network may include a plurality of nodes, and functions corresponding to each node are different, and when a function corresponding to any one node in a network is in an on state, it may be determined that the network corresponding to any one node is a awakened network, that is, the awakened network may be determined according to the network corresponding to the function in the on state in the vehicle.
Step 230, if the awakened network is detected, acquiring network information of the awakened network, wherein the network information of the awakened network includes a node address of the awakened network, awakened information of the awakened network and maintenance information of the awakened network.
As one way, when the presence of a awakened network is detected, network information of the awakened network may be determined from network messages sent by the awakened network. Optionally, the node address of the awakened network may be included in the network message of the awakened network, and then the corresponding awakening information and maintenance information are determined based on the node address. Optionally, a mapping relationship between the node address of each network in the vehicle and the corresponding wake-up information and maintenance information may be predetermined, and after determining the node address of the awakened network, wake-up information and maintenance information of the non-dormant network are determined based on the mapping relationship, so as to obtain network information of the awakened network.
The wake-up information of the awakened network is a reason for each awakening the network, and the maintenance information of the awakened network is a reason for maintaining the awakening of the network. Alternatively, the wake-up reasons for the awakened network may include passive wake-up reasons and active wake-up reasons for the network. Alternatively, there is and only one wake-up reason for each wake-up of the network in the vehicle.
Step 240, if it is determined that the number of times of awakening the awakened network is greater than the number threshold, determining an awakening abnormal node according to the node address of the awakened network, and determining awakening abnormal information of the awakening abnormal node according to the awakening information of the awakened network and the maintenance information of the awakened network.
In one way, the network in the vehicle may be awakened by a person, for example, when a passenger gets off a taxi, a door of the taxi is opened and closed continuously, and the network corresponding to the door is awakened continuously, so that in order to accurately determine whether the awakened network in the vehicle is in an awakened abnormal state, the determination needs to be made according to the awakening times of the awakened network, and when the awakening times of the awakened network are greater than a time threshold, the awakened network is determined to be in an awakened abnormal state. The frequency threshold may be set according to actual needs, and is not specifically limited herein.
As one way, the vehicle may include a plurality of networks, where each network may include a plurality of nodes, and when all nodes under a network are dormant, the corresponding network is in a dormant state, and if any node is in an un-dormant state, the network may be determined to be a awakened network. It can be understood that the cause of the awakening anomaly of the awakened network is related to the cause of the awakening anomaly of each node in the awakened network, in order to determine the cause of the awakening anomaly of the awakened network, the corresponding awakening anomaly node needs to be determined according to the node address of the awakened network, and then the cause of the awakening anomaly node is determined based on the awakening information and the maintenance information of the awakened network, so that the cause of the awakening of the awakened network can be determined. Optionally, the wake-up information of the awakened network and the maintenance information of the awakened network include a wake-up source and a maintenance source of each node in the awakened network.
In some embodiments, after step 240, the method further comprises: acquiring node information of the awakening abnormal node, and sending the node information of the awakening abnormal node to a gateway of the vehicle so that the gateway records the awakening abnormal node, wherein the node information of the awakening abnormal node comprises a node address of the awakening abnormal node and the awakening abnormal reason.
As one mode, each network in the vehicle interacts with the bus network, after determining the cause of the awakening abnormality of the awakening abnormal node, the bus network receives a network message sent by the awakened network, determines the node address and the awakening abnormality cause of the awakening abnormal node in the network message, packages the network message to obtain the node information of the awakening abnormal node, then sends the node information of the awakening abnormal node to the gateway, and the gateway records the awakening abnormal node after receiving the node information of the awakening abnormal node.
Optionally, after receiving the node information of the awakening abnormal node, the gateway records the node information of the awakening abnormal node in a local database of the vehicle, so that a driver can check and overhaul conveniently; the gateway can also upload the node information of the awakening abnormal node to the cloud server, so that a vehicle developer can optimally upgrade the vehicle based on the node information of the awakening abnormal node; the gateway can also send the node information of the awakening abnormal node to the electronic equipment in communication connection with the vehicle, and the electronic equipment prompts the user after receiving the node information so that the user can process in real time.
In this embodiment, after the non-dormant network is not detected in the standby mode of the vehicle, the awakened network of the vehicle is detected, so that when it is determined that the awakened network exists, the node address, the awakening information, the maintenance information and the awakening times of the awakened network are determined, and then when the awakening abnormality of the awakened network is determined according to the awakening times, the awakening abnormal node and the awakening abnormality information of the awakening abnormal node can be determined according to the node address, the awakening information and the maintenance information, the abnormal awakening network and the awakening abnormality cause can be rapidly positioned, the efficiency of determining the awakening abnormality of the vehicle is improved, and the difficulty of determining the awakening abnormality is reduced.
Referring to fig. 3, fig. 3 illustrates a method for determining sleep wakeup anomalies according to an embodiment of the present application. The method for determining the sleep wakeup abnormality specifically may include the following steps:
If it is determined that the usage mode of the vehicle is the standby mode, step 310 is performed, whether an unsecured network exists in the network of the vehicle is detected.
If it is detected that the non-dormant network is not present, step 320 is performed, detecting whether a awakened network is present in the network of the vehicle.
Step 330, if the presence of the awakened network is detected, acquiring network information of the awakened network, where the network information of the awakened network includes a node address of the awakened network, awakening information of the awakened network, and maintenance information of the awakened network.
The specific step descriptions of steps 310-330 can refer to the specific step descriptions of steps 210-230, and are not described herein.
Step 340, determining the awakening times of the awakened network in the process of changing the use mode of the vehicle.
As one way, in order to avoid that a normal awakened network is determined to be in an abnormal awakened state by mistake during normal use of the vehicle by a driver or a passenger, the number of awakenings of the awakened network is periodically determined, so as to determine whether the awakened network is in the abnormal awakened state. The change in the usage pattern of the vehicle may be set as a condition for determining the number of awakenings of the awakened network. When the wake-up network is determined to exist, the corresponding usage mode of the vehicle may be a standby mode or other usage modes (such as a driving mode, an energy-saving mode, etc.), and the wake-up times of the wake-up network are determined in the process that the vehicle is changed from the standby mode to the other usage modes or the other usage modes are changed to the standby mode, so that the wake-up abnormality of the wake-up network is determined more accurately.
As another way, if the number of times of awakening the awakened network is greater than the number threshold value in a short time, it may also be determined that the awakened network is in an abnormal state of awakening, a determined duration for determining the number of times of awakening may also be preset, and based on the number of times of awakening the awakened network corresponding to the determined duration, the number of times of awakening the awakened network in the determined duration may be compared with the number of times threshold value, so that the determination that the awakened network is in an abnormal state of awakening is more accurate.
And 350, when the use mode of the vehicle is changed again, clearing the determined awakening times, and re-determining the awakening times of the awakened network in the process.
As one way, when the usage mode of the vehicle changes again, it may be determined that the network in the vehicle performs a sleep-wake cycle at this time, and in order to determine the accuracy of wake abnormality determination of the wake-up network and the determination of the cause of the wake-up abnormality, it is necessary to determine the number of wake-up times of the wake-up network again, that is, to clear the determined number of wake-up times. Alternatively, the awakened network may also be redetermined when the usage pattern of the vehicle changes again.
Step 360, if it is determined that the number of awakenings of the awakened network is greater than the number threshold, determining an awakening abnormal node according to the node address of the awakened network, and determining awakening abnormal information of the awakening abnormal node according to the awakening information of the awakened network and the maintenance information of the awakened network.
The specific step description of step 360 may refer to the specific step description of step 240, and will not be described herein.
In some embodiments, step 360 further comprises: if the awakened times of the awakened network are determined to be larger than a times threshold value, alarm information is generated; and carrying out wake-up abnormal alarm prompt according to the alarm information.
