Description

Technical Field

[0001] The present invention relates to the technical field of automobile communications, and in particular to a method for judging and processing abnormal awakening of a vehicle network node. Background Art

[0002] In vehicle network management, if any wake-up source of a network node is activated, the network will be requested and the entire vehicle network will be awakened. If the wake-up sources of all network nodes are turned off, the network will be released and the entire vehicle network will be dormant. If a network node cannot be turned off due to abnormal triggering of its own wake-up source, the entire vehicle network will not be able to enter dormancy, thereby causing the risk of vehicle power feeding. For network nodes connected to switching devices, it is easy for the switch to get stuck or have poor contact. Once the switch is stuck in the activated state or the activated and inactivated states are constantly jumping, if the network node does not have a diagnostic mechanism for the switch abnormality, it will be regarded as a valid wake-up source, thereby continuously requesting the network, and the network will always be in the awakened state. Generally, the gateway will monitor the network abnormality of the entire vehicle network, only locate the abnormally awakened network node and perform reminder alarms and other processing, but it cannot prevent or optimize the network abnormality, nor can it determine the root cause of the abnormality, and it is of no substantial help to the owner's reminder. Therefore, it is necessary to provide a judgment and processing method for abnormal awakening of vehicle network nodes to solve the above problems. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method for determining and processing abnormal awakening of a vehicle network node, so as to solve the problems existing in the above-mentioned background technology.

[0004] The present invention is implemented as follows: a method for judging and processing abnormal awakening of a vehicle network node, the method comprising the following steps:

[0005] Determining, by means of an on-board electronic controller unit, a trigger type of a switch device in a network node, wherein the trigger type includes effective wake-up, switch stuck, and switch contact failure;

[0006] When the trigger type is switch stuck or switch contact is poor, a switch fault report is made in the NM message. If there is no switch fault report in the NM message, it is considered as normal wake-up; otherwise, the network node is considered as abnormal wake-up;

[0007] Receive the NM message of the network node through the gateway, and learn the abnormal reason of vehicle sleep: the switch is stuck or the switch contact is poor;

[0008] The vehicle's current location is obtained through the navigation system, the nearest 4S repair shop is matched, and the distance between the vehicle's current location and the 4S repair shop is sent back to the vehicle network;

[0009] A processing reminder message is sent out according to the current battery voltage and the current battery power. The processing reminder message is to be able to continue to request to wake up the network or to stop sending NM messages and release the network.

[0010] As a further solution of the present invention: the step of determining the trigger type of the switch device in the network node by the on-board electronic controller unit specifically includes:

[0011] The high and low signals of the switch device are detected by the on-board electronic controller unit, 1 is a high signal, the switch is turned on; 0 is a low signal, the switch is turned off;

[0012] Determine the trigger type of the switching device. If the high signal 1 state is maintained for time △t≤T threshold, the trigger type is effective wake-up; if the high signal 1 state is maintained for time △t>T threshold, the trigger type is switch stuck; if the jump frequency f between 0 and 1>fmax, the trigger type is poor switch contact.

[0013] As a further solution of the present invention: the network node that wakes up the entire vehicle network due to switch sticking or poor switch contact is marked as a network abnormal node, and the T threshold and fmax are fixed values ​​calibrated according to the characteristics of the switch.

[0014] As a further solution of the present invention: after the whole vehicle is turned off and powered off, when there is no wake-up source to trigger the network node, the NM message is stopped and the network is released; when there is a network node that is awakened due to the hard line triggering of the switch, the NM message is sent in the network segment, and the remaining network nodes receive the NM message and are awakened to respond to network needs.

[0015] As a further solution of the present invention: in the step of obtaining the current position of the vehicle through the navigation system, matching the nearest 4S repair shop, and sending the distance between the current position of the vehicle and the 4S repair shop back to the vehicle network, the number of 4S repair shops is two.

[0016] As a further solution of the present invention: the step of sending the distance between the current position of the vehicle and the 4S repair shop back to the vehicle network also includes:

[0017] Calculate the battery voltage threshold V required to drive the vehicle to the 4S repair shop threshold And the power battery power threshold SOC threshold , V threshold and SOC threshold The specific value of is dynamically calibrated according to the distance between the vehicle's current location and the 4S repair shop identified by the navigation system, where the threshold value of the farther 4S repair shop is: V threshold1 and SOC threshold1 , the threshold of the next far 4s repair shop: V threshold2 and SOC threshold2 ;

[0018] Obtain the vehicle's current battery voltage V from the vehicle network through the gateway battery Electric vehicles also need to obtain the power SOC of the power battery BMS , gateway to V Battery and SOC BMS Conduct real-time monitoring;

[0019] When V Battery >V threshold1 or SOC BMS >SOC threshold1 , the vehicle sleep abnormality and the root cause will be reported through the Internet of Vehicles system: a certain node switch is stuck or the switch contact is poor; and the vehicle owner will be reminded of the vehicle sleep abnormality and the root cause through the mobile client: a certain node switch is stuck or the switch contact is poor;

[0020] When V Battery ≤V threshold1 or SOC BMS ≤SOC threshold1 , report vehicle sleep abnormalities and root causes through the Internet of Vehicles system: a certain node switch is stuck or the switch is in poor contact; and remind the owner of the vehicle sleep abnormalities and root causes through the mobile client: a certain node switch is stuck or the switch is in poor contact, and push the two nearest 4S repair shops to the user, reminding the user of the remaining power and remaining mileage;

[0021] When detecting V Battery <V threshold2 or SOC BMS <SOC threshold2 , report the vehicle sleep abnormality and the root cause through the Internet of Vehicles system: a node switch is stuck or the switch has poor contact; and remind the owner of the vehicle sleep abnormality and the root cause through the mobile client: a node switch is stuck or the switch has poor contact, remind the user of the remaining power and remaining mileage. If the power is too low to drive to the nearest 4S shop, please contact the maintenance personnel for on-site processing.

[0022] As a further solution of the present invention: the step of issuing processing reminder information according to the current battery voltage and the current battery power specifically includes:

[0023] When V Battery >V threshold1 or SOC BMS >SOC threshold1 , then the fault report is made in the NM message: the switch is stuck or the switch contact is poor, and the vehicle can continue to request to wake up the network and send the NM message. In this case, the vehicle is abnormally awakened and does not enter sleep;

[0024] When V Battery ≤V threshold1 or SOC BMS≤SOC threshold1 The fault report is made in the NM message: the switch is stuck or the switch contact is poor, the NM message is stopped, and the network is released. If there is no other wake-up demand for the vehicle network, the vehicle can go into sleep mode to reserve enough power for the owner to drive the vehicle to the maintenance point.

[0025] As a further solution of the present invention: when the vehicle is in the OFF gear sleep state, when a network node is awakened due to a local event triggering the vehicle, the vehicle network will be awakened. At this time, a reliability sending mechanism will be used to ensure that the event message can be successfully received and processed by the receiving node.

[0026] As a further solution of the present invention: the step of using a reliable sending mechanism to send an event message specifically includes:

[0027] A local wake-up source triggers the first node;

[0028] The first node sends a first frame message in the network, where the first frame message is a network management message;

[0029] The first node starts to send application messages in the network, excluding event messages triggered by the event;

[0030] The second node is awakened by the network management message of the first node in the network, and sends a first frame message;

[0031] The second node starts sending application messages in the network;

[0032] The first node receives the application message from the second node, performs a reliability handshake, makes a conditional judgment, and then sends out an event message including the current trigger.

The switch connected to the pin of the vehicle electronic controller unit (ECU) is a jump detection type switch. The ECU diagnostic strategy is to detect the high and low signals of the switch. The step of determining the trigger type of the switch device in the network node through the vehicle electronic controller unit specifically includes: detecting the high and low signals of the switch device through the vehicle electronic controller unit, 1 is a high signal, the switch is turned on; 0 is a low signal, the switch is turned off; then determine the trigger type of the switch device, if the high signal 1 state is maintained for time △t≤T threshold, the trigger type is effective wake-up; if the high signal 1 state is maintained for time △t>T threshold, the trigger type is switch stuck; if the jump frequency f between 0 and 1 is>fmax, the trigger type is poor switch contact, and the network node that wakes up the entire vehicle network due to switch stuck or poor switch contact is marked as a network abnormal node, and the T threshold and fmax are fixed values ​​calibrated according to the characteristics of the switch.

[0050] like Figure 3 As shown, in the embodiment of the present invention, the gateway receives the NM message from the network node to learn the abnormal reason of the vehicle sleep: the switch is stuck or the switch is in poor contact; then the current position of the vehicle is obtained through the navigation system, the nearest 4s repair shop is matched, and the distance between the current position of the vehicle and the 4s repair shop is sent back to the vehicle network. The number of 4s repair shops is two. And the battery voltage threshold V required to drive the vehicle to the 4s repair shop is calculated threshold And the power battery power threshold SOC threshold , V threshold and SOC threshold The specific value of is dynamically calibrated according to the distance between the vehicle's current location and the 4S repair shop identified by the navigation system, where the threshold value of the farther 4S repair shop is: Vthreshold1 and SOC threshold1 , the threshold of the next far 4s repair shop: V threshold2 and SOC threshold2 ; Obtain the vehicle's current battery voltage V from the vehicle network through the gateway battery Electric vehicles also need to obtain the power SOC of the power battery BMS , gateway to V Battery and SOC BMS Real-time monitoring; when V Battery >V threshold1 or SOC BMS >SOC threshold1 , the vehicle sleep abnormality and the root cause are reported through the Internet of Vehicles system: a node switch is stuck or the switch is in poor contact; and the vehicle owner is reminded of the vehicle sleep abnormality and the root cause through the mobile client: a node switch is stuck or the switch is in poor contact; when V Battery ≤V threshold1 or SOC BMS ≤SOC threshold1 , report the abnormal vehicle sleep and the root cause through the Internet of Vehicles system: a certain node switch is stuck or the switch is in poor contact; and remind the owner of the abnormal vehicle sleep and the root cause through the mobile client: a certain node switch is stuck or the switch is in poor contact, and push the two nearest 4S repair shops to the user, reminding the user of the remaining power and remaining mileage; when the V Battery <V threshold2 or SOC BMS <SOC threshold2 , report the vehicle sleep abnormality and the root cause through the Internet of Vehicles system: a node switch is stuck or the switch has poor contact; and remind the owner of the vehicle sleep abnormality and the root cause through the mobile client: a node switch is stuck or the switch has poor contact, remind the user of the remaining power and remaining mileage. If the power is too low to drive to the nearest 4S shop, please contact the maintenance personnel for on-site processing.

[0051] In the embodiment of the present invention, when V Battery >V threshold1 or SOC BMS >SOC threshold1 , a first-level alarm is issued. For example, the reminder content of the first-level alarm is: Your car is now in an abnormal wake-up state, which may be caused by a switch stuck, please handle it in time; when V Battery ≤V threshold1 or SOC BMS ≤SOC threshold1, a second-level alarm is issued. For example, the reminder content of the second-level alarm is: Your car is now in an abnormal wake-up state, which may be caused by the switch being stuck. The power SOC = 20%, and the remaining mileage is 10km. Two nearest 4s repair shops have been recommended for you: XX4s shop and XX4s shop. Please handle it in time; when V is detected Battery <V threshold2 or SOC BMS <SOC threshold2 , issuing a level three alarm.

When V Battery ≤V threshold1 or SOC BMS ≤SOC threshold1 The fault report is made in the NM message: the switch is stuck or the switch contact is poor, the NM message is stopped, and the network is released. If there is no other wake-up demand for the vehicle network, the vehicle can go into sleep mode to reserve enough power for the owner to drive the vehicle to the maintenance point.

[0053] In an embodiment of the present invention, when a vehicle is in the OFF gear sleep state, when a certain network node is awakened due to a local event trigger, the vehicle network will be awakened. At this time, a reliability sending mechanism will be used to ensure that the event message can be successfully received and processed by the receiving node.
