[0023] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] The execution subject of the sensor message channel identification method of the present application can be an engine control unit (Electronic Control Unit, ECU). A plurality of sensors are installed on the vehicle, and the sensors are used to monitor the temperature, concentration value and other parameters in each component of the vehicle's post-processing assembly. These parameters are then sent to the bus (Controller Area Network, CAN) through messages. The ECU reads the data on the bus, processes different messages according to the message address, and updates the value to the program to monitor the composition of the vehicle's exhaust gas.

[0026] Figure 1 A flow chart showing the steps of a sensor message channel identification method of the present application is shown. Figure 1 , a sensor message channel identification method includes the following steps S101 to S103:

[0027] S101. Obtain message information on a transmission channel.

[0028] In this embodiment, the ECU includes multiple message hardware channels, for example, CAN1, CAN2, and CAN3. Each sensor can be connected to a certain message hardware channel to send the collected sensor parameters to the ECU. The sensor parameters are sent in the form of messages. Each message has a sensor address corresponding to the sensor, that is, the message information includes the sensor address and the sensor parameters.

[0029] Among them, the ways in which the sensor sends message information include request type and periodic sending type. The request type means that the sensor does not actively send message information, and the sensor sends the message after the ECU sends a request. The periodic sending type means that the sensor actively sends messages continuously at a certain period. Therefore, the message information includes request type messages and periodic messages.

[0030] In this embodiment, obtaining the message information on the transmission channel includes: after sending a message request to the sensor through the transmission channel, receiving the request message sent by the sensor; and receiving the periodic message sent by the sensor. That is, there are two ways for the ECU to obtain the message information on the transmission channel. One is to actively send a message request to the sensor, and after the sensor responds to the message request, it sends the message information, and the ECU then obtains the message information. The other is that the ECU passively receives the periodic message sent by the sensor. In the above way, the ECU can monitor the message information sent by the sensors on all transmission channels.

[0031] After acquiring the message information on the transmission channel, this embodiment also includes: acquiring pre-stored sensor data, the sensor data including a one-to-one correspondence between sensor information, message information and transmission channel; when the message information on the transmission channel is inconsistent with the message information in the sensor data, executing the step of determining the target channel.

[0032] It is understandable that during the first use or update of the vehicle, the ECU needs to be adapted to the vehicle for the first time, that is, initialized. The purpose of initialization is to determine the corresponding relationship between the vehicle post-processing sensor and its corresponding message transmission channel and store it in the ECU. The ECU can pre-select and store sensor data, that is, the relationship between the vehicle's sensor and its corresponding transmission channel is pre-stored in the ECU. When the vehicle is initialized, the message information on the transmission channel obtained by the ECU can be directly compared with the pre-stored sensor data to see if they are consistent. If they are consistent, the message information is directly parsed. If they are inconsistent, it means that some sensor data of the current vehicle does not exist in the ECU, and step S102 is executed to store all sensor data of the current vehicle and the corresponding transmission channel of the sensor message in the ECU.

[0033] In this embodiment, if the message information on the transmission channel is consistent with the message information in the sensor data, the pre-stored sensor data can meet the common data of most vehicles, thereby speeding up the speed of sensor message channel recognition and reducing the initialization time. If the message information on the transmission channel is inconsistent with the message information in the sensor data, adaptive recognition of the sensor and the transmission channel is performed, that is, step S102 is executed, which can adapt to the post-processing sensors of different vehicles and make them universal for all models.

[0034] S102: When the message information meets a preset condition, determine the transmission channel as a target channel.

[0035] It is understandable that when the number of sensors and buses is too large, wiring errors are likely to occur, such as connecting a sensor to multiple buses, or connecting the buses of multiple sensors to each other incorrectly. In this case, sensor data errors will occur. In this regard, the present embodiment identifies the message information by setting preset conditions. The preset conditions include that the message information has a unique transmission channel and the message information is valid, thereby ensuring that each sensor has a unique transmission channel and that the message information received from the transmission channel is valid. When the vehicle first collects parameters, the transmission channel corresponding to each sensor can be identified, and the correspondence between the sensor and the transmission channel can be determined. When the parameters are collected next time, the sensor parameters can be automatically obtained from the transmission channel corresponding to the sensor, thereby greatly improving the accuracy and completeness of sensor parameter collection.

[0036] in, Figure 2 A flowchart of the steps of determining the target channel according to an embodiment of the present application is shown. When the message information meets the preset conditions, the transmission channel is determined to be the target channel. Figure 2 , determining the target channel includes the following steps S201 to S203:

[0037] S201. Detect whether there is a preset sensor message in the message information. If yes, detect the transmission channel information where the message information is located.

[0038] In this embodiment, the preset sensor message is the message information in the above-mentioned pre-stored sensor data, which can be the address information or sensor type corresponding to the various sensors set by the management personnel according to the information of the current vehicle. For example, the preset sensor message in the ECU includes the address and temperature parameters of the temperature sensor A, the address and temperature parameters of the temperature sensor B, the address and concentration parameters of the concentration sensor C, and the address and concentration parameters of the concentration sensor D. The message information obtained by the ECU through the transmission channel includes the address and temperature parameters of the temperature sensor A, the address and concentration parameters of the concentration sensor C, and the address and concentration parameters of the concentration sensor D. Then, the message information corresponding to the temperature sensor A, the concentration sensor C, and the concentration sensor D are all consistent with the preset sensor message. At this time, the transmission channel information where the message information corresponding to the temperature sensor A, the concentration sensor C, and the concentration sensor D is located, and the detected message information does not include the message information of the temperature sensor B. At this time, the transmission channel information where the message information corresponding to the temperature sensor A, the concentration sensor C, and the concentration sensor D is located is detected, and an alarm message that the message information of the temperature sensor B does not exist is issued.

[0039] S202: When the transmission channel information indicates that the message information is transmitted through a unique transmission channel, determine the transmission channel as a target channel.

[0040] In this embodiment, the transmission channel information where the message information is located includes bus information of the transmission channel where the message information is located and the number of the transmission channels where the message information is located. The message information may be transmitted to the ECU through one transmission channel or through multiple transmission channels. When the message information is transmitted to the ECU through one transmission channel, the transmission channel information indicates that the message information is transmitted through a unique transmission channel. Combined with step S201, it can be seen that at this time, the message information is consistent with the preset sensor message and is transmitted through a unique transmission channel, indicating that this transmission channel is the correct transmission channel for the corresponding sensor, and the transmission channel is determined to be the target channel.

[0041] When the message information is transmitted to the ECU through multiple transmission channels, the validity of the message information needs to be verified, that is, step S203 is executed.

[0042] S203: When the transmission channel information indicates that the message information is transmitted through multiple transmission channels, detect the validity of the message information, and use the transmission channel where the valid message information is located as the target channel.

[0043] Specifically, detecting the validity of the message information includes: parsing the message information to obtain sensor parameters; and determining that the message information is valid when the sensor parameters are within a first preset range and the difference between the sensor parameters and the comparison parameters is within a second preset range.

[0044] The first preset range of this embodiment can be set according to the type of sensor. For example, the first preset range corresponding to the temperature parameter of the temperature sensor is -40°C to 40°C, and the first preset range corresponding to the concentration parameter of the concentration sensor is 32% to 33%.

[0045] In this embodiment, the comparison parameter may be a sensor parameter of the same type at other locations of the vehicle. For example, the message information includes the temperature parameter of the urea tank temperature sensor on the post-processing assembly of the vehicle, and the comparison parameter is other comparison temperature values ​​such as the ambient temperature of the engine on the vehicle or the engine water temperature. The comparison parameter may also be a standard value set according to the vehicle performance.

[0046] When the sensor parameter is within the first preset range, and the difference between the sensor parameter and the comparison parameter is within the second preset range, the message information is determined to be valid. For example, the message information includes the temperature parameter of the urea tank temperature sensor on the post-processing assembly of the vehicle, the message information is transmitted via the CAN5 bus, the temperature parameter is within the first preset range, the comparison parameter is the standard value, and the difference between the temperature parameter and the standard value is within the second preset range, then the message information of the urea tank temperature sensor is valid, and the CAN5 bus transmission channel where the message information of the urea tank temperature sensor is located is used as the target channel.

[0047] In this embodiment, taking the transmission channel where the valid message information is located as the target channel includes: when there is only one transmission channel for the valid message information, taking the transmission channel where the valid message information is located as the target channel; when there are multiple transmission channels for the valid message information, taking any transmission channel where the valid message information is located as the target channel.

[0048] For example, the ECU collects message information S on transmission channels CAN1, CAN2, and CAN3. In order to determine the only transmission channel for the message information S, the validity of the message information S on CAN1, CAN2, and CAN3 is verified respectively. Through the above validity verification method, it is found that only the message information S on CAN2 is valid, and CAN2 is set as the target transmission channel for the message information S.

[0049] If it is obtained through the above validity verification method that the message information S on CAN1 and CAN2 are both valid, then any transmission channel of CAN1 and CAN2 can be selected as the target transmission channel of the message information S.

[0050] It should be noted that, in order to make one sensor correspond to one transmission channel, in the above example, if the message information S on CAN1 and CAN2 are both valid, then after selecting CAN1 as the target transmission channel for the message information S, the message information S on CAN1 and CAN2 is continuously obtained. When the parameters contained in the message information S of CAN1 differ greatly from the parameters contained in the message information S on CAN2, the validity of the message information S on CAN1 and CAN2 is re-verified until the unique transmission channel for the message information S is obtained and used as the target channel for the message information S.

[0051] S103: Take the target channel and the sensor information corresponding to the message information as target data, and store the target data.

[0052] For example, the target channel of the message information S is CAN2, and the sensor corresponding to the message information S is the urea tank temperature sensor. Then, CAN2 is bound to the address of the urea tank temperature sensor and stored in the ECU as permanent data. During driving, the vehicle can automatically receive the sensor parameters according to the transmission channel corresponding to the sensor.

[0053] The method of this embodiment also includes: issuing an alarm message when a sensor message channel identification fails; wherein the sensor message channel identification fails include that the message information does not exist in the preset sensor message; or, the message information is invalid; or, valid message information exists on multiple transmission channels.

[0054] For example, if the ECU detects that the preset sensor messages do not exist in the messages on all sensor channels, it will issue a message timeout fault alarm. For example, if the sensor parameters obtained by parsing the message information are not within the first preset range, it will issue a data unreliable alarm. For another example, if the ECU collects message information S on the transmission channels CAN1, CAN2, and CAN3, it will issue a channel error alarm. It should be noted that if the ECU reports a fault, it will periodically re-monitor the message, and delete the alarm information when the fault is repaired.

[0055] The above is a sensor message channel identification method provided by this embodiment. By acquiring the message information on the transmission channel, it is determined whether the message information meets the preset conditions. The preset conditions include that the message information has a unique transmission channel and the message information is valid. When the message information meets the preset conditions, the transmission channel is determined to be the target channel, and then the target channel and the sensor information corresponding to the message information are stored as target data. This can realize adaptive identification of the sensor and its message information transmission channel, making it universal for all vehicle models and avoiding problems caused by sensor wiring errors. Moreover, since this embodiment can adaptively identify the transmission channel, ECU manufacturers no longer need to generate multiple data for different post-processing sensors. A set of maintenance data of sensor channel address message data can merge all vehicles, greatly reducing the trouble in data management and improving the management and maintenance efficiency of vehicle post-processing sensor data.

[0056] This embodiment further provides a sensor message channel identification device, which is used to execute the sensor message channel identification method described in the above embodiment.

[0059] The storage module 303 is used to take the target channel and the sensor information corresponding to the message information as target data and store the target data.

[0060] In a feasible example, the message information includes request messages and periodic messages, and the information acquisition module 301 is further used to receive request messages sent by the sensor after sending a message request to the sensor through the transmission channel; and receive periodic messages sent by the sensor.

[0061] In a feasible example, the target channel determination module 302 is also used to obtain pre-stored sensor data after obtaining the message information on the transmission channel, and the sensor data includes a one-to-one correspondence between sensor information, message information and transmission channel; when the message information on the transmission channel is inconsistent with the message information in the sensor data, the step of determining the target channel is executed.

[0062] In a feasible example, the target channel determination module 302 is also used to detect whether there is a preset sensor message in the message information. If so, detect the transmission channel information where the message information is located; when the transmission channel information indicates that the message information is transmitted through a unique transmission channel, determine that the transmission channel is the target channel; when the transmission channel information indicates that the message information is transmitted through multiple transmission channels, detect the validity of the message information and use the transmission channel where the valid message information is located as the target channel.

[0063] In a feasible example, the target channel determination module 302 is also used to parse the message information to obtain sensor parameters; when the sensor parameters are within a first preset range and the difference between the sensor parameters and the comparison parameters is within a second preset range, the message information is determined to be valid.

[0064] In a feasible example, the target channel determination module is also used to, when there is only one transmission channel for the valid message information, use the transmission channel where the valid message information is located as the target channel; when there are multiple transmission channels for the valid message information, use any transmission channel where the valid message information is located as the target channel.

[0065] In a feasible example, the target channel determination module 302 is also used to issue an alarm message when a sensor message channel identification fails; wherein the sensor message channel identification failure includes that the message information does not exist in the preset sensor message; or, the message information is invalid; or, valid message information exists on multiple transmission channels.
