[0001] The present application relates to the field of vehicles, and in particular to a controller detection method, device, vehicle sub-controller and vehicle controller. Background Art

[0002] At present, there are more and more intelligent control modules on cars, including automatic transmission, ABS system, in-car entertainment and audio-visual system, four-wheel drive torque distribution system, active suspension system, airbag + seat belt system, Tbox, etc. The versions of these control systems need to be updated frequently to improve driving reliability. However, when the version in the control system is not the latest version or the required version, it may cause system operation failure or mismatch problems. Summary of the invention

[0003] In view of the above problems, the present application provides a controller detection method, device, vehicle sub-controller and whole vehicle controller. The vehicle sub-controller can actively upload its own parameter information to the whole vehicle controller according to a preset period, so that the whole vehicle controller can upload the parameter information of the sub-controller to the server, so that the server can compare the parameter information and realize controller monitoring and reminder.

[0004] In a first aspect, the present application provides a controller detection method, which is applied to a sub-controller of a vehicle, and the method includes: determining that the vehicle is in a preset operating condition; and sending parameter information of the sub-controller to the vehicle controller according to a preset period.

[0005] In the technical solution of the embodiment of the present application, when the vehicle is in a preset working condition, for example, the preset working condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. When the vehicle controller receives the parameter information of the sub-controller, it uploads the parameter information to a server (for example, a cloud server) by wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information. When it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

[0006] In some embodiments, the preset working condition includes one of the following working conditions: the diagnostic function of the vehicle controller is abnormal; the vehicle controller does not have the diagnostic function; the sub-controller actively uploads information. This enables the vehicle to realize the diagnostic function of parameter information under different working conditions, thereby improving the reliability and stability of the vehicle operation.

[0007] In some embodiments, the parameter information of the sub-controller is sent to the vehicle controller according to a preset period, including: sending the parameter information of the sub-controller to the vehicle controller according to the priority order of each sub-controller. Thus, when the vehicle includes multiple sub-controllers, the parameter information of each sub-controller can be uploaded to the vehicle controller according to the priority order of each sub-controller, thereby improving the safety of the vehicle.

[0008] In some embodiments, the parameter information of the sub-controller includes at least one of the following: software version information, hardware version information, control instructions, operating parameters, and fault information of the sub-controller. When the vehicle is in the early stage of research and development and the vehicle controller does not have a self-diagnosis function, the sub-controller actively uploads its own parameter information to the vehicle controller, such as the parameter information including software version information, hardware version information, manufacturer information, etc., to achieve self-inspection and monitoring of the controller; after the vehicle leaves the factory, when the vehicle controller has a self-diagnosis function, the sub-controller can still actively report parameter information and achieve redundant backup with the vehicle controller, such as the parameter information including software version information, control instructions, operating parameters, fault information, etc., to improve the reliability of the vehicle.

[0009] In some embodiments, the controller detection method further includes: uploading the parameter information of the sub-controller to the vehicle controller when receiving an upload instruction from the vehicle controller. The sub-controller can not only actively upload its own parameter information to the vehicle controller, but also upload its own parameter information to the vehicle controller when receiving an upload instruction from the vehicle controller, thereby reducing bandwidth usage and improving transmission rate.

[0010] In the second aspect, the present application provides a controller detection method, which is applied to the vehicle controller of a vehicle, and the method includes: determining that the vehicle is in a preset operating condition; receiving parameter information of the sub-controller sent by the sub-controller in the vehicle according to a preset period; and uploading the parameter information of the sub-controller to a server.

[0011] In the technical solution of the embodiment of the present application, when the vehicle is in a preset working condition, for example, the preset working condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. The vehicle controller receives the parameter information sent by the sub-controller, and uploads the software version information of the sub-controller to a server (for example, a cloud server) through wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information, and when it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

[0012] In some embodiments, the preset working condition includes one of the following working conditions: the diagnostic function of the vehicle controller is abnormal; the vehicle controller does not have the diagnostic function; the sub-controller actively uploads information. This enables the vehicle to realize the diagnostic function of parameter information under different working conditions, thereby improving the reliability and stability of the vehicle operation.

[0013] In some embodiments, before uploading the parameter information of the sub-controller to the server, the method also includes: encrypting the parameter information of all sub-controllers to obtain encrypted parameter information; uploading the encrypted parameter information to the server via wireless communication, thereby improving the safety and reliability of the entire vehicle.

[0014] In some embodiments, receiving the parameter information of the sub-controller sent by the sub-controller in the vehicle according to a preset period includes: receiving the parameter information of the sub-controller according to the priority order of each sub-controller. Thus, when the vehicle includes multiple sub-controllers, the parameter information can be uploaded to the vehicle controller according to the priority order of each sub-controller, thereby improving the safety of the vehicle.

[0015] In some embodiments, the controller detection method described above further includes: when it is determined that the vehicle is not in a preset operating condition, obtaining parameter information of each sub-controller, the parameter information of the sub-controller includes at least one of the software version information, control instructions, operating parameters, fault information, and hardware version information of the sub-controller. After the vehicle leaves the factory, when the whole vehicle controller has a self-diagnosis function, the sub-controller can still actively report parameter information and realize redundant backup with the whole vehicle controller, such as parameter information including: software version information, control instructions, operating parameters, fault information, etc., to improve the reliability of the whole vehicle. When the vehicle is in the early stage of research and development and the whole vehicle controller does not have a self-diagnosis function, the sub-controller actively uploads its own parameter information to the whole vehicle controller, such as parameter information including software version information, hardware version information, manufacturer information, etc., to realize self-inspection and monitoring of the controller.

The device includes: a first determination module, used to determine whether the vehicle is in a preset operating condition; and a sending module, used to send parameter information of the sub-controller to the vehicle controller according to a preset period.

[0017] In the technical solution of the embodiment of the present application, when the first determination module determines that the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, and the sub-controller uploads its own parameter information to the vehicle controller through the sending module according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. When the vehicle controller receives the parameter information of the sub-controller, it uploads the parameter information to the server (for example, a cloud server) through wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information. When it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

[0018] In the fourth aspect, the present application provides a controller detection device, which is applied to the vehicle controller of a vehicle. The device includes: a second determination module, used to determine whether the vehicle is in a preset operating condition; a receiving module, used to receive parameter information of the sub-controller sent by the sub-controller in the vehicle according to a preset period; an uploading module, used to upload the parameter information of the sub-controller to the server.

[0019] In the technical solution of the embodiment of the present application, when the second determination module determines that the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. The vehicle controller receives the parameter information sent by the sub-controller through the receiving module, and uploads the parameter information of the sub-controller to the server through the uploading module, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information. When it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0042] At present, the software version information of each sub-controller of the vehicle is obtained through the automatic diagnosis of the vehicle's TBOX. The principle is to use the diagnostic protocol in a question-and-answer manner, that is, the vehicle controller actively obtains the software version information from each sub-controller. The vehicle has the self-diagnosis function only when the vehicle has been mass-produced or is about to enter the mass production stage. In the early stage of prototype development, the vehicle's diagnostic function has not been developed, and it does not have the ability to obtain the software version information of each sub-controller through self-diagnosis. Or when the vehicle's self-diagnosis function fails, the controller's software version cannot be obtained, which may lead to functional failures.

[0043] To this end, the present application first defines the CAN / LIN frame message of each sub-controller to represent the software version information of each sub-controller. Each sub-controller communicates through CAN / LIN and actively reports its own software version information in a periodic manner to the vehicle controller. The vehicle controller passively receives the software version information reported by each sub-controller and uploads the received software version information to the server so that the server can compare the software version information and issue a notification based on the comparison results.

[0044] The controller detection method disclosed in the embodiment of the present application can be used for various sub-controllers in a vehicle with an integrated chassis, such as a controller for a battery system, a controller for a motor system, a controller for a suspension system, a controller for a braking system, etc.

[0045] For the convenience of explanation, the following embodiments are combined Figure 1 The controller detection method of the present application is described.

[0046] Reference Figure 1 The controller detection method in this application, applied to a sub-controller of a vehicle, may include the following steps:

[0047] S101, determining that the vehicle is in a preset operating condition.

[0048] S102, sending the parameter information of the sub-controller to the vehicle controller according to a preset period, wherein the preset period can be calibrated according to actual conditions.

[0049] Specifically, when the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, or the self-diagnosis function of the vehicle controller is abnormal, or it is pre-defined that the sub-controller actively uploads its own parameter information, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. When the vehicle controller receives the parameter information of the sub-controller, it uploads the parameter information to a server (for example, a cloud server) via wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information, and when it is determined that the software version information of the sub-controller is not the latest version, a reminder is issued, thereby realizing monitoring and reminders of the controller.

[0050] In some embodiments, after receiving the parameter information uploaded by the sub-controller, the vehicle controller also aggregates and encrypts the parameter information of all sub-controllers, and uploads the encrypted information to the server, which decrypts the encrypted information, decomposes the decrypted information, and makes a one-to-one correspondence with each sub-controller, and compares it with the corresponding reference parameter information to obtain a comparison result. Among them, the encryption method used by the vehicle controller corresponds to the decryption method used by the server.

[0051] In some embodiments, the preset operating condition includes one of the following operating conditions: an abnormality occurs in the diagnostic function of the vehicle controller; the vehicle controller does not have a diagnostic function; the sub-controller actively uploads information.

[0052] That is to say, in the early stage of prototype development, when the self-diagnosis function of the whole vehicle is not fully developed, the whole vehicle controller cannot actively obtain the parameter information of each sub-controller, and cannot monitor the parameter information of the vehicle; or after the vehicle is put into use, the diagnostic function of the whole vehicle controller becomes abnormal and cannot actively obtain the parameter information of the sub-controller; or it is customized that the sub-controller actively uploads its own parameter information to the whole vehicle controller. This enables the vehicle to realize the controller's diagnostic function under different working conditions and improve the reliability and stability of the whole vehicle operation.

[0053] In some embodiments, the parameter information of the sub-controllers is sent to the vehicle controller according to a preset period, including: sending the parameter information of the sub-controllers to the vehicle controller according to the priority order of each sub-controller.

[0054] Specifically, each sub-controller communicates with the vehicle controller through CAN / LIN, and each sub-controller corresponds to a CAN node. The priority order of the corresponding sub-controller is determined according to the preset CAN node ID. For example, the CAN node ID is 1, 2, 3, ..., N, then the priority order of the sub-controller corresponding to the CAN node with ID 1 is the highest, and the priority order of the sub-controller corresponding to the CAN node with ID 2 is the second highest, and so on, the priority order of each sub-controller can be determined. According to the priority order of each sub-controller, the parameter information of the sub-controller is sent to the vehicle controller in sequence. Therefore, when the vehicle includes multiple sub-controllers, it can be uploaded to the vehicle controller according to the priority order of each sub-controller to improve the safety of the vehicle. It should be noted that the parameter information in each sub-controller also has a priority order. For example, the parameter information of the sub-controller includes control instructions, software version information, hardware version information, manufacturer information, etc. It can be pre-set that the software version information has the highest priority order, the control instruction has the second highest priority order, and the hardware version information and manufacturer information have a gradually decreasing priority order.

[0055] In some embodiments, the parameter information of the sub-controller includes at least one of the software version information, hardware version information, control instructions, operating parameters, and fault information of the sub-controller.

[0056] Specifically, when the vehicle has a diagnostic function or leaves the factory, when the diagnostic function of the vehicle controller is detected to be abnormal, that is, the vehicle controller cannot actively obtain the parameter information of the sub-controller from the sub-controller; or, after the vehicle leaves the factory, when the sub-controller is set to actively upload parameter information, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle, such as the parameter information including software version information, hardware version information, operating parameters, control instructions, fault information, etc., so that the vehicle controller performs the next operation according to the parameter information sent by the sub-controller. For example, when the parameter information includes software version information, the software version information is uploaded to the server so that the server compares the software version information with the reference version information corresponding to the sub-controller, and issues a reminder notification based on the comparison result. For another example, when the parameter information includes motor operating parameters, the vehicle controller determines the operating status of the motor based on the motor operating parameters. For another example, when the parameter information includes fault information, the sub-controller of the battery system uploads the temperature sensor abnormality to the vehicle controller so that the vehicle controller can take the next countermeasure.

[0057] When the vehicle controller is normal and there is no pre-set sub-controller to actively upload information, the vehicle controller actively obtains the parameter information of the sub-controller. When the diagnostic function of the vehicle controller is abnormal, the sub-controller actively uploads its own parameter information. This provides redundant backup of information transmission between the sub-controller and the main controller, thereby providing reliability for the entire vehicle.

[0058] When the vehicle is in the early stage of research and development and the vehicle controller does not have the self-diagnosis function, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle. For example, the parameter information includes software version information, hardware version information, manufacturer information, etc. After receiving the software version information, hardware version information, manufacturer information, etc. uploaded by the sub-controller, the vehicle controller will upload it to the server. The server will compare the parameter information and send notification reminders based on the comparison results to realize self-inspection and monitoring of the controller.

[0059] In some embodiments, the controller detection method described above further includes: upon receiving an upload instruction from the vehicle controller, uploading parameter information of the sub-controller to the vehicle controller.

[0060] That is to say, when the diagnostic function of the vehicle control is normal and there is no pre-defined parameter information for the sub-controller to upload its own parameter information, the vehicle controller can actively obtain the parameter information of the sub-controller. When the sub-controller receives the upload instruction from the vehicle controller, it uploads its own parameter information to the vehicle controller, thereby reducing the bandwidth occupied by the sub-controller when uploading parameter information periodically and improving the transmission rate.

[0061] As a specific example, Figure 2 As shown, multiple sub-controllers include controller 1, controller 2, and controller x, and the vehicle controller includes TBox / VCU. The vehicle controller uses a 4G / 5G module to upload to the cloud server through a base station. Among them, controller 1, controller 2, and controller x are connected to the TBox / VCU controller through CAN / LIN cables respectively. The frame format of the version information is defined through the CAN / LIN communication protocol, and the version information of each controller is sent to the TBox / VCU controller through the CAN protocol cycle.

[0062] The TBox / VCU controller reads the frame signal of each controller version information through the CAN / LIN communication protocol. After parsing, it summarizes the information according to certain rules, encrypts it, and then sends it to the base station through the 4G / 5G module sending interface.

[0063] The cloud server receives the encrypted version information from the base station through the 4G / 5G module receiving interface, decrypts it, decomposes and analyzes the information, and converts it into the software version information of each controller. The version information of each controller is compared with the version information benchmark of each controller of the integrated chassis saved by the cloud server, and the comparison results are sent to the user.

[0064] It should be noted that the above embodiment is described by taking the vehicle controller using a 4G / 5G module to upload to the cloud server through a base station as an example. It can also be uploaded to the cloud server through wireless communication methods such as wifi (mobile hotspot), Bluetooth, zegbee (ZigBee protocol), RFID (Radio Frequency Identification), NFC (Near Field Communication), etc., which is not limited here.

[0065] To sum up, in the technical solution of the embodiment of the present application, when the vehicle is in a preset working condition, for example, the preset working condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. When the vehicle controller receives the parameter information of the sub-controller, it uploads the parameter information to the server by wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information. When it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

[0066] Corresponding to the above-mentioned embodiment, the present application also proposes a controller detection method, which is applied to the vehicle controller of a vehicle.

[0067] like Figure 3 As shown, the controller detection method of the present application may include the following steps:

[0068] S201, determining that the vehicle is in a preset operating condition.

[0069] S202, receiving parameter information of a sub-controller sent by a sub-controller in a vehicle according to a preset period.

[0070] S203, uploading the software version information of the sub-controller to the server.

[0071] Specifically, when the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, or the self-diagnosis function of the vehicle controller is abnormal, or it is pre-defined that the sub-controller actively uploads its own parameter information, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. The vehicle controller receives the parameter information sent by the sub-controller, and uploads the parameter information of the sub-controller to a server (for example, a cloud server) via wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information, and when it is determined that the software version information of the sub-controller is not the latest version, a reminder is issued, thereby realizing monitoring and reminders of the controller.

[0072] In some embodiments, the preset operating condition includes one of the following operating conditions: an abnormality occurs in the diagnostic function of the vehicle controller; the vehicle controller does not have a diagnostic function; the sub-controller actively uploads information.

[0073] That is to say, in the early stage of prototype development, when the self-diagnosis function of the whole vehicle is not fully developed, the whole vehicle controller cannot actively obtain the parameter information of each sub-controller, and cannot monitor the parameter information of the vehicle; or after the vehicle is put into use, the diagnostic function of the whole vehicle controller is abnormal, and the parameter information of the sub-controller cannot be actively obtained; or it is customized that the sub-controller actively uploads its own parameter information to the whole vehicle controller. This enables the vehicle to realize the controller's diagnostic function under different working conditions and improve the reliability and stability of the whole vehicle operation.

[0074] In some embodiments, before uploading the parameter information of each sub-controller to the server, the method further includes: encrypting the parameter information of all sub-controllers to obtain encrypted parameter information; and uploading the encrypted parameter information to the server via wireless communication.

[0075] Specifically, after receiving the parameter information uploaded by the sub-controller, the vehicle controller also summarizes and encrypts the parameter information of all sub-controllers, and uploads the encrypted information to the server. The server decrypts the encrypted information, and then decomposes the decrypted information, one-to-one corresponds to each sub-controller, and compares it with the corresponding reference parameter information to obtain the comparison result. Among them, the encryption method used by the vehicle controller and the decryption method used by the server are corresponding, which can improve the safety and reliability of the whole vehicle.

[0076] In some embodiments, receiving parameter information of the sub-controller sent by each sub-controller in the vehicle according to a preset period includes: receiving the parameter information of the sub-controller according to the priority order of each sub-controller.

[0077] Specifically, each sub-controller communicates with the vehicle controller through CAN / LIN, and each sub-controller corresponds to a CAN node. The priority order of the corresponding sub-controller is determined according to the preset CAN node ID. For example, the CAN node ID is 1, 2, 3, ..., N, then the sub-controller corresponding to the CAN node with ID 1 has the highest priority order, and the sub-controller corresponding to the CAN node with ID 2 has the second highest priority order. By analogy, the priority order of each sub-controller can be determined. The vehicle controller can obtain the priority order of the sub-controller according to the ID of the CAN node of each sub-controller, and then receive the parameter information sent by the sub-controller according to the priority order. Therefore, when the vehicle includes multiple sub-controllers, each sub-controller can be uploaded to the vehicle controller according to the priority order of each sub-controller, thereby improving the safety of the vehicle. It should be noted that the parameter information in each sub-controller also has a priority order. For example, the parameter information of the sub-controller includes control instructions, software version information, hardware version information, manufacturer information, etc. It can be pre-set that the software version information has the highest priority order, the control instruction has the second highest priority order, and the hardware version information and manufacturer information have a gradually decreasing priority order.

[0078] In some embodiments, the above-mentioned controller detection method also includes: when it is determined that the vehicle is not in a preset operating condition, obtaining parameter information of each sub-controller, the parameter information of the sub-controller also includes at least one of the software version information, control instructions, operating parameters, fault information, and hardware version information of the sub-controller.

[0079] Specifically, when the vehicle has a diagnostic function or leaves the factory, when the diagnostic function of the vehicle controller is detected to be abnormal, that is, the vehicle controller cannot actively obtain the parameter information of the sub-controller from the sub-controller; or, after the vehicle leaves the factory, when the sub-controller is set to actively upload parameter information, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle, such as the parameter information including software version information, hardware version information, operating parameters, control instructions, fault information, etc. uploaded to the vehicle controller, so that the vehicle controller performs the next operation according to the parameter information sent by the sub-controller. For example, when the parameter information includes software version information, the software version information is uploaded to the server so that the server compares the software version information with the reference version information corresponding to the sub-controller, and issues a reminder notification based on the comparison result. For another example, when the parameter information includes motor operating parameters, the vehicle controller determines the operating status of the motor based on the motor operating parameters. For another example, when the parameter information includes fault information, the sub-controller of the battery system uploads the temperature sensor abnormality to the vehicle controller so that the vehicle controller can take the next countermeasure.

[0080] When the vehicle controller is normal and there is no pre-set sub-controller to actively upload information, the vehicle controller actively obtains the parameter information of the sub-controller. When the diagnostic function of the vehicle controller is abnormal, the sub-controller actively uploads its own parameter information. This provides redundant backup of information transmission between the sub-controller and the main controller, thereby providing reliability for the entire vehicle.

[0081] When the vehicle is in the early stage of research and development and the vehicle controller does not have the self-diagnosis function, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle. For example, the parameter information includes software version information, hardware version information, manufacturer information, etc. After receiving the software version information, hardware version information, manufacturer information, etc. uploaded by the sub-controller, the vehicle controller will upload it to the server. The server will compare the parameter information and send notification reminders based on the comparison results to realize self-inspection and monitoring of the controller.

[0082] In some embodiments, the vehicle controller also sends an upload instruction to the sub-controller, and the sub-controller responds to the upload instruction of the vehicle controller and uploads its own parameter information to the vehicle controller, thereby reducing the bandwidth occupied by the sub-controller when regularly uploading parameter information and improving the transmission rate.

[0083] It should be noted that for details not disclosed in the controller detection method of the present application, please refer to the details disclosed in the controller detection method of the first embodiment of the present application, and the details will not be repeated here.

[0084] Corresponding to the first aspect embodiment, the present application also proposes a controller detection device, which is applied to a sub-controller of a vehicle.

[0085] Reference Figure 4 As shown, the controller detection device 100 of the present application includes: a first determination module 110, used to determine whether the vehicle is in a preset operating condition; a sending module 120, used to send parameter information of the sub-controller to the vehicle controller according to a preset period.

[0086] Specifically, when the first determination module 110 determines that the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, or the self-diagnosis function of the vehicle controller is abnormal, or it is pre-defined that the sub-controller actively uploads its own parameter information, the sub-controller uploads its own parameter information to the vehicle controller through the sending module 120 according to a preset period, the parameter information may include the software version information, hardware information, etc. of the sub-controller. When the vehicle controller receives the software version information of the sub-controller, it may upload the parameter information to the server (for example, a cloud server) by wireless transmission, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information, and when it is determined that the software version information of the sub-controller is not the latest version, a reminder is given, thereby realizing monitoring and reminder of the controller.

[0087] In some embodiments, the preset operating condition includes one of the following operating conditions: an abnormality occurs in the diagnostic function of the vehicle controller; the vehicle controller does not have a diagnostic function; the sub-controller actively uploads information.

[0088] That is to say, in the early stage of prototype development, when the self-diagnosis function of the whole vehicle is not fully developed, the whole vehicle controller cannot actively obtain the parameter information of each sub-controller, and cannot monitor the parameter information of the vehicle; or after the vehicle is put into use, the diagnostic function of the whole vehicle controller becomes abnormal and cannot actively obtain the parameter information of the sub-controller; or it is customized that the sub-controller actively uploads its own parameter information to the whole vehicle controller. This enables the vehicle to realize the controller's diagnostic function under different working conditions and improve the reliability and stability of the whole vehicle operation.

[0089] In some embodiments, the sending module 120 sends the parameter information of the sub-controller to the vehicle controller according to a preset period, and is specifically used to: send the parameter information of the sub-controller to the vehicle controller according to the priority order of each sub-controller.

[0090] Specifically, each sub-controller communicates with the vehicle controller via CAN / LIN, and each sub-controller corresponds to a CAN node. The priority order of the corresponding sub-controller is determined according to the preset CAN node ID. For example, if the CAN node ID is 1, 2, 3, ..., N, then the priority order of the sub-controller corresponding to the CAN node with ID 1 is the highest, and the priority order of the sub-controller corresponding to the CAN node with ID 2 is the second highest, and so on, the priority order of each sub-controller can be determined. Each sub-controller sends the parameters of the sub-controller to the vehicle controller in sequence through the sending module 120 according to the priority order. Therefore, when the vehicle includes multiple sub-controllers, each sub-controller can be uploaded to the vehicle controller according to the priority order, thereby improving the safety of the vehicle.

[0091] In some embodiments, the parameter information of the sub-controller includes at least one of the software version information, hardware version information, control instructions, operating parameters, and fault information of the sub-controller.

[0092] Specifically, when the vehicle has a diagnostic function or leaves the factory, when the diagnostic function of the vehicle controller is detected to be abnormal, that is, the vehicle controller cannot actively obtain the parameter information of the sub-controller from the sub-controller; or, after the vehicle leaves the factory, when the sub-controller is set to actively upload parameter information, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle, such as the parameter information including software version information, hardware version information, operating parameters, control instructions, fault information, etc. uploaded to the vehicle controller, so that the vehicle controller performs the next operation according to the parameter information sent by the sub-controller. For example, when the parameter information includes software version information, the sending module 120 uploads the software version information to the server, so that the server compares the software version information with the reference version information corresponding to the sub-controller, and issues a reminder notification according to the comparison result. For another example, when the parameter information includes motor operating parameters, the vehicle controller determines the operating status of the motor according to the motor operating parameters. For another example, when the parameter information includes fault information, for example, the sub-controller of the battery system uploads the temperature sensor abnormality to the vehicle controller through the sending module 120, so that the vehicle controller can take the next countermeasure.

[0093] When the vehicle controller is normal and there is no pre-set sub-controller to actively upload information, the vehicle controller can actively obtain the parameter information of the sub-controller. When the diagnostic function of the vehicle controller is abnormal, the sub-controller actively uploads its own parameter information through the sending module 120, thereby performing redundant backup of information transmission between the sub-controller and the main controller to provide reliability of the entire vehicle.

[0094] When the vehicle is in the early stage of research and development and the vehicle controller does not have a self-diagnosis function, the sub-controller actively uploads its own parameter information to the vehicle controller through the sending module 120 according to the set cycle. For example, the parameter information includes software version information, hardware version information, manufacturer information, etc. After receiving the software version information, hardware version information, manufacturer information, etc. uploaded by the sub-controller, the vehicle controller will upload it to the server. The server will compare the parameter information and send a notification reminder based on the comparison result to realize self-inspection and monitoring of the controller.

[0095] In some embodiments, the sending module 120 is further used to upload the parameter information of the sub-controller to the vehicle controller upon receiving an upload instruction from the vehicle controller.

[0096] That is to say, when the diagnostic function of the vehicle control is normal and there is no pre-defined parameter information for the sub-controller to upload itself, the vehicle controller can actively obtain the parameter information of the sub-controller. When the sub-controller receives the upload instruction from the vehicle controller, the sub-controller uploads its own parameter information to the vehicle controller through the sending module 120, thereby reducing the bandwidth occupied by the sub-controller when uploading parameter information periodically and improving the transmission rate.

[0097] It should be noted that for details not disclosed in the controller detection device of the embodiment of the present application, please refer to the details disclosed in the controller detection method of the embodiment of the first aspect of the present application, and the details will not be repeated here.

[0098] Corresponding to the embodiment of the second aspect, the present application proposes a controller detection device, which is applied to the vehicle controller of a vehicle.

[0099] See also Figure 5 As shown, the controller detection device 200 of the present application includes: a second determination module 210, used to determine whether the vehicle is in a preset operating condition; a receiving module 220, used to receive parameter information of the sub-controller sent by the sub-controller in the vehicle according to a preset period; an uploading module 230, used to upload the parameter information of the sub-controller to the server.

[0100] Specifically, when the second determination module 210 determines that the vehicle is in a preset operating condition, for example, the preset operating condition may be the early stage of prototype vehicle development, the vehicle controller does not have a self-diagnosis function, or the self-diagnosis function of the vehicle controller is abnormal, or it is pre-defined that the sub-controller actively uploads its own parameter information, and the sub-controller uploads its own parameter information to the vehicle controller according to a preset period. The parameter information may include software version information, hardware information, etc. of the sub-controller. The vehicle controller receives the parameter information sent by the sub-controller through the receiving module 220, and uploads the parameter information of the sub-controller to the server (for example, a cloud server) through the uploading module 230, so that the server compares the parameter information of the sub-controller with the reference parameter information of the sub-controller, for example, to determine whether the software version information of the sub-controller is the latest version information, and when it is determined that the software version information of the sub-controller is not the latest version, a reminder is issued, thereby realizing monitoring and reminder of the controller.

[0101] In some embodiments, the preset operating condition includes one of the following operating conditions: an abnormality occurs in the diagnostic function of the vehicle controller; the vehicle controller does not have a diagnostic function; the sub-controller actively uploads information.

[0102] That is to say, in the early stage of prototype development, when the self-diagnosis function of the whole vehicle is not fully developed, the whole vehicle controller cannot actively obtain the parameter information of each sub-controller, and cannot monitor the parameter information of the vehicle; or after the vehicle is put into use, the diagnostic function of the whole vehicle controller is abnormal, and the parameter information of the sub-controller cannot be actively obtained; or it is customized that the sub-controller actively uploads its own parameter information to the whole vehicle controller. This enables the vehicle to realize the controller's diagnostic function under different working conditions and improve the reliability and stability of the whole vehicle operation.

[0103] In some embodiments, the upload module 230 is also used to encrypt the parameter information of all sub-controllers before uploading the parameter information of each sub-controller to the server to obtain encrypted parameter information; and upload the encrypted parameter information to the server via wireless communication.

[0104] Specifically, after receiving the parameter information uploaded by the sub-controller through the receiving module 220, the whole vehicle controller also summarizes and encrypts the parameter information of all sub-controllers through the uploading module 230, and uploads the encrypted information to the server, and the server decrypts the encrypted information, and then decomposes the decrypted information, one-to-one corresponds to each sub-controller, and compares it with the corresponding reference parameter information to obtain a comparison result. Among them, the encryption method used by the whole vehicle controller and the decryption method used by the server are corresponding, so as to improve the safety and reliability of the whole vehicle.

[0105] In some embodiments, the receiving module 220 receives the parameter information of the sub-controller sent by each sub-controller in the vehicle according to a preset period, and is specifically used to: receive the parameter information of the sub-controller according to the priority order of each sub-controller.

[0106] Specifically, each sub-controller communicates with the vehicle controller via CAN / LIN, and each sub-controller corresponds to a CAN node. The priority order of the corresponding sub-controller is determined according to the preset CAN node ID. For example, if the CAN node ID is 1, 2, 3, ..., N, then the priority order of the sub-controller corresponding to the CAN node with ID 1 is the highest, and the priority order of the sub-controller corresponding to the CAN node with ID 2 is the second highest, and so on, the priority order of each sub-controller can be determined. The vehicle controller can obtain the priority order of the sub-controller according to the ID of the CAN node of each sub-controller, and then receive the parameter information sent by the sub-controller through the receiving module 230 according to the priority order. Therefore, when the vehicle includes multiple sub-controllers, each sub-controller can be uploaded to the vehicle controller according to the priority order, thereby improving the safety of the vehicle.

[0107] In some embodiments, the second determination module 210 is also used to: when it is determined that the vehicle is not in a preset operating condition, obtain parameter information of each sub-controller, and the parameter information of the sub-controller also includes at least one of the software version information, control instructions, operating parameters, fault information, and hardware version information of the sub-controller.

[0108] Specifically, when the vehicle has a diagnostic function or leaves the factory, when the diagnostic function of the vehicle controller is detected to be abnormal, that is, the vehicle controller cannot actively obtain the parameter information of the sub-controller from the sub-controller; or, after the vehicle leaves the factory, when the sub-controller is set to actively upload parameter information, the sub-controller actively uploads its own parameter information to the vehicle controller according to the set cycle, such as the parameter information including software version information, hardware version information, operating parameters, control instructions, fault information, etc. uploaded to the vehicle controller, so that the vehicle controller performs the next operation according to the parameter information sent by the sub-controller. For example, when the parameter information includes software version information, the software version information is uploaded to the server through the upload module 230, so that the server compares the software version information with the reference version information corresponding to the sub-controller, and issues a reminder notification according to the comparison result. For another example, when the parameter information includes motor operating parameters, the vehicle controller determines the operating status of the motor according to the motor operating parameters. For another example, when the parameter information includes fault information, the sub-controller of the battery system uploads the temperature sensor abnormality to the vehicle controller so that the vehicle controller can take the next countermeasure.

[0109] When the vehicle controller is normal and there is no pre-set sub-controller to actively upload information, the vehicle controller actively obtains the parameter information of the sub-controller. When the diagnostic function of the vehicle controller is abnormal, the sub-controller actively uploads its own parameter information. This provides redundant backup of information transmission between the sub-controller and the main controller, thereby providing reliability for the entire vehicle.

[0110] When the vehicle is in the early stage of research and development and the vehicle controller does not have a self-diagnosis function, the sub-controller actively uploads its own parameter information to the vehicle controller according to a set period. For example, the parameter information includes software version information, hardware version information, manufacturer information, etc. uploaded to the vehicle controller. The vehicle controller receives the software version information, hardware version information, manufacturer information, etc. uploaded by the sub-controller through the receiving module 220, and then uploads it to the server through the uploading module 230. The server compares the parameter information and sends a notification reminder based on the comparison result to realize self-inspection and monitoring of the controller.

[0111] In some embodiments, the vehicle controller also sends an upload instruction to the sub-controller, and the sub-controller responds to the upload instruction of the vehicle controller and uploads its own parameter information to the vehicle controller, thereby reducing the bandwidth occupied by the sub-controller when regularly uploading parameter information and improving the transmission rate.
