Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0061] Figure 1 : is a system architecture diagram of a vehicle upgrade management method provided by an embodiment of the present application. Figure 1 As shown, the vehicle upgrade management method provided in the embodiment of the present application can be applied to the vehicle to realize the process of charging the power battery. The system architecture provided in the embodiment of this specification mainly includes a vehicle 10 and a server 20, and the vehicle 10 includes a policy manager 11 and an electronic control unit 12. Among them, the vehicle 10 can be a motor vehicle, such as a hybrid vehicle or an electric vehicle; the policy manager 11 can be a control unit in the vehicle for managing and adjusting the upgrade policy; the electronic control unit 12 can be a control unit in the vehicle for performing various tasks to ensure the operation of the vehicle; the server 20 can be a server for generating upgrade policies, such as a large server, a small server or a personal computer.

[0062] In the related technology, when performing OTA on the vehicle's on-board software, the method adopted is to send the OTA upgrade task to the vehicle, and the vehicle executes the ECU (electronic Control Unit) upgrade according to the upgrade strategy in the OTA task. However, when executing the ECU upgrade, there is a situation where the upgrade strategy in the OTA does not match the ECU to be upgraded in the vehicle, or the ECU in the vehicle is removed or malfunctions, resulting in the failure of the ECU upgrade, which may further damage the ECU, causing economic losses to the vehicle and even high safety risks.

[0063] According to the embodiment of the present application, the policy manager 11 in the motor vehicle 10 obtains a first upgrade strategy for at least one electronic control unit in the vehicle from the server 20, generates a first upgrade list based on the first upgrade strategy, the first upgrade list includes at least one upgrade item, and the at least one upgrade item includes a hardware identifier of each electronic control unit and a group identifier corresponding to the upgrade item to which the hardware identifier belongs. The policy manager 11 generates a connection status request and transmits it to the electronic control unit 12 to determine the connection status of each electronic control element 12 based on each hardware identifier, obtains a target hardware identifier with an abnormal connection status in each hardware identifier, adjusts at least one upgrade item in the first upgrade list based on the target hardware identifier, obtains a second upgrade list, adjusts the group identifier of each hardware identifier in the first upgrade strategy based on the second upgrade list, and generates a second upgrade strategy.

[0064] based on Figure 1 The system architecture shown below will be combined with Figure 2-Figure 6 , the vehicle upgrade management method provided in the embodiment of the present application is introduced in detail.

[0065] See also Figure 2 , is a flow chart of a vehicle upgrade management method provided in an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101-S105.

[0066] S101, obtaining a first upgrade strategy for at least one electronic control unit in a vehicle, and generating a first upgrade list based on the first upgrade strategy;

[0067] In one embodiment, a first upgrade strategy for at least one electronic control unit of a vehicle is obtained. The electronic control unit may be a component in the vehicle for executing various control instructions. The first upgrade strategy may be an execution strategy for upgrading the electronic control component. The first upgrade strategy may include a hardware identifier, a software identifier, a group identifier, and upgrade content of at least one electronic control component. The hardware identifier may be an identifier for indicating the electronic control unit. There may be a one-to-one correspondence between the hardware identifier and the electronic control unit. The group identifier may be a group corresponding to an upgrade project to which each electronic control component belongs when being upgraded in the first upgrade strategy. The hardware identifier and the group identifier in the first upgrade strategy are extracted to generate a first upgrade list. The first upgrade list includes at least one upgrade project. The at least one upgrade project includes the hardware identifier of each electronic control unit and the group identifier corresponding to the upgrade project to which the hardware identifier belongs.

[0068] It is understandable that there is a one-to-one correspondence between the hardware identifier and the software identifier. Therefore, in order to improve processing efficiency, a feasible method is to extract only the hardware identifier, determine the software identifier corresponding to the electronic control unit based on the hardware identifier, and then obtain the software code corresponding to the software identifier.

[0069] S102, determining the connection status of each electronic control element based on each hardware identifier;

[0070] In one embodiment, a connection status request corresponding to each electronic control unit is generated based on each hardware identifier, each connection status request is transmitted to the corresponding electronic control unit, a connection status instruction returned by the electronic control unit is received, and the connection status instruction is parsed to determine the connection status corresponding to the circuit control unit. The connection status may be a state that represents the electronic control unit receiving data through the network. If the connection status is a normal state, it can be considered that the electronic control unit can receive the upgrade data packet; if the connection status is an abnormal state, it can be considered that the electronic control unit may not be able to receive the upgrade data packet. The upgrade data packet may be a data packet used to upgrade the electronic control unit. It can be understood that since the upgrade data packet needs to be transmitted to the electronic control unit to upgrade the electronic control unit, it is necessary to ensure that the connection status of the electronic control unit is in a normal state to ensure that the upgrade data packet can be transmitted to the electronic control unit.

[0071] S103, obtaining a target hardware identifier whose connection state is abnormal from each hardware identifier, and adjusting at least one upgrade item in the first upgrade list based on the target hardware identifier to obtain a second upgrade list;

[0072] In one embodiment, a target hardware identifier whose connection status is abnormal is obtained from each hardware identifier in the first upgrade list, a target upgrade item corresponding to the target hardware identifier is deleted from the first upgrade list, and the first group identifier of the remaining upgrade items included in the first upgrade list after deleting the target hardware item is adjusted. The remaining upgrade items may be the upgrade items in the first upgrade list except the target upgrade item, and a second upgrade list is obtained. The second upgrade list may be a list including upgrade items whose connection status is normal.

[0073] Specifically, the method for adjusting the first group identifiers of the remaining upgrade items may be: adjusting the first group identifiers of the remaining upgrade items according to the numerical relationship between the first group identifiers of the remaining upgrade items adjacent to the target upgrade item and the first group identifiers of the target upgrade item.

[0074] S104, adjusting the group identifier of each hardware identifier in the first upgrade strategy based on the second upgrade list to generate a second upgrade strategy;

[0075] In one embodiment, based on the remaining upgrade items in the second upgrade list, target upgrade items included in the second upgrade list but not included in the first upgrade policy are determined, the target hardware identifiers in the first upgrade policy are deleted, and the hardware identifiers in the first upgrade policy are adjusted according to the group identifiers corresponding to the remaining upgrade items in the second upgrade list to generate a second upgrade policy. The second upgrade policy can be an execution policy that includes upgrade items whose connection status is normal.

[0076] S105, performing an upgrade process on each electronic control unit based on a second upgrade strategy;

[0077] In one embodiment, based on the numerical value of the group identifier included in each upgrade project in the second upgrade strategy, each electronic control unit in the second upgrade strategy is upgraded in turn. The upgrade process can be to transmit the upgrade data package corresponding to the upgrade project to the corresponding electronic control unit according to the upgrade content included in the upgrade project, and upgrade the hardware corresponding to the hardware identifier of the electronic control unit and the software program corresponding to the software identifier according to the upgrade data package. The upgrade content can be the content of adjusting the structure of the hardware or the function of the software program.

[0078] Specifically, a feasible method for upgrading each electronic control unit in sequence may be: based on the numerical value of the group identifier, the electronic control units belonging to the same group identifier are upgraded in sequence from small to large. It is understandable that another feasible method may be to upgrade each electronic control unit in sequence from large to small based on the numerical value of the group identifier and the numerical value or alphabetical order of each hardware identifier, which may be set according to actual conditions.

[0079] In an embodiment of the present application, by adjusting the first upgrade list corresponding to the first upgrade strategy according to the connection status of the electronic control unit in the first upgrade strategy to obtain the second upgrade list, adjusting the first upgrade strategy according to the second upgrade list to obtain the second upgrade strategy, and upgrading the electronic control unit based on the second upgrade strategy, thereby determining the connection status of the electronic control unit and removing the upgrade items corresponding to the target hardware identifier with an abnormal connection status in the first upgrade strategy, so that the upgrade data packet used for the upgrade processing can be transmitted to the electronic control unit, thereby improving the accuracy of the upgrade of the electronic control unit and the safety of vehicle components.

[0080] The following will be combined Figure 3 A vehicle upgrade management method provided in an embodiment of the present application is described in detail with reference to a specific example.

[0081] S201, obtaining a first upgrade strategy for at least one electronic control unit in a vehicle, and at least one upgrade item in the first upgrade strategy;

[0082] In one embodiment, a first upgrade strategy for at least one electronic control unit of a vehicle is obtained. The electronic control unit may be a component in the vehicle for executing various control instructions. The first upgrade strategy may be an execution strategy for upgrading the electronic control component. The first upgrade strategy may include a hardware identifier, a software identifier, a group identifier, and upgrade content of at least one electronic control component. The hardware identifier may be an identifier for indicating the electronic control unit. There may be a one-to-one correspondence between the hardware identifier and the electronic control unit. The group identifier may be a group corresponding to an upgrade project to which each electronic control component belongs when being upgraded in the first upgrade strategy. The first upgrade list includes at least one upgrade project. The at least one upgrade project includes the hardware identifier of each electronic control unit and the group identifier corresponding to the upgrade project to which the hardware identifier belongs.

[0083] It is understandable that there is a one-to-one correspondence between the hardware identifier and the software identifier. Therefore, in order to improve processing efficiency, a feasible method is to extract only the hardware identifier, determine the software identifier corresponding to the electronic control unit based on the hardware identifier, and then obtain the software code corresponding to the software identifier.

[0084] S202, determining a first upgrade sequence number of each hardware identifier based on the group identifier of each upgrade project, and generating a first upgrade list corresponding to the first upgrade strategy based on each hardware identifier and each first upgrade sequence number;

[0085] In one embodiment, the hardware identification and group identification in the first upgrade strategy are extracted, the group identification of each upgrade item is determined as the first upgrade serial number of each hardware identification, and the first upgrade list corresponding to the first upgrade strategy is generated based on each hardware identification and the first upgrade serial number corresponding to the hardware identification.

[0086] For example, as shown in Figure 4, extract Figure 4 The hardware identifiers "ECU1", "ECU2" and "ECU3" and the group identifiers "GPR1", "GPR2" and "GPR3" of the first upgrade strategy are converted into corresponding first upgrade numbers to generate a first upgrade list. The first upgrade number "1" in the first upgrade list is converted from "GPR1", the first upgrade number "2" is converted from "GPR2", and the first upgrade number "3" is converted from "GPR3".

[0087] S203, generating a connection status request for each hardware identifier, and determining a request sequence number for each connection status request;

[0088] In one embodiment, a connection status request corresponding to each hardware identifier is generated. The connection status request may be a request for determining the connection status of the electronic control unit corresponding to the hardware identifier. The connection status requests are sorted, and a request sequence number of each connection status request is determined. The request sequence number may be a transmission order representing the connection status request. It can be understood that by sorting the connection status requests, it is convenient to obtain the connection status of the electronic control unit in an orderly and accurate manner according to the connection status request according to the request sequence number of each connection status request, thereby improving the accuracy and efficiency of obtaining the connection status of the electronic control unit according to the connection status request.

[0089] Specifically, the method for determining the request serial number of the connection status request can be: based on each hardware identifier in the first upgrade list, the corresponding request serial number is set in numerical or alphabetical order; it can also be based on the first upgrade serial number corresponding to each hardware identifier. The serial numbers are sorted in numerical order, and the hardware identifiers with the same first upgrade serial number are set with the corresponding request serial number according to the numerical or alphabetical order included in the hardware identifier. The specific setting can be made according to the actual situation.

[0090] For example, the hardware identifiers include "ECU1", "ECU2" and "ECU3", and the corresponding request numbers generated may be "RE1", "RE2" and "RE3".

[0091] S204, based on the request sequence number of each connection status request, query the status of each electronic control unit in turn according to each connection status request, and obtain the connection status instruction returned for each connection status request;

[0092] In one embodiment, based on the request serial number of each connection status request, the connection status request is transmitted to the corresponding electronic control unit in order from small to large according to the numerical value of the request serial number, so as to query the connection status of each electronic control unit and obtain the connection status instruction returned by the electronic control unit in response to the connection status request. The connection status instruction can be an instruction generated and returned by the electronic control unit in response to the connection status request, and is used to characterize the network status of the electronic control unit receiving data.

[0093] Among them, a feasible method is to set up a connection query device in the vehicle, which receives the first upgrade list transmitted by the policy manager and the connection status request corresponding to each electronic control unit in the first upgrade list, transmits each connection status request to the corresponding electronic control unit to query the connection status of the electronic control unit, and receives the connection status instruction returned by the electronic control unit.

[0094] S205, parsing each connection status instruction to determine the connection status of the electronic control unit corresponding to each hardware identifier;

[0095] In one embodiment, the connection queryer parses the acquired connection status instruction, determines the connection status of the electronic control unit corresponding to the hardware identifier indicated in the connection status instruction, updates the connection status of each hardware identifier in the first upgrade list, and transmits the updated first upgrade list to the policy manager. If the connection status is normal, it can be considered that the electronic control unit can receive the upgrade data packet; if the connection status is abnormal, it can be considered that the electronic control unit may not be able to receive the upgrade data packet, and the upgrade data packet can be a data packet used to upgrade the electronic control unit.

[0096] It should be noted that when the connection status of the electronic control unit corresponding to the hardware identifier is not determined, the connection status recorded by the hardware identifier in the first upgrade list can be set to blank or normal, which can be set according to actual conditions.

[0097] It is understandable that since upgrading the electronic control unit requires transmitting the upgrade data package to the electronic control unit, it is necessary to ensure that the connection status of the electronic control unit is in a normal state to ensure that the upgrade data package can be transmitted to the electronic control unit.

[0098] Furthermore, in order to avoid the inability to obtain the connection status instruction returned by the electronic control unit in response to the connection status request due to the inability of the electronic control unit to receive the connection status request, a feasible method may be: if the connection status instruction returned by the electronic control unit is not received within the preset time length, the connection status of the electronic control unit is marked as an abnormal state, and the specific value of the preset time length can be set based on the actual situation, for example, it can be 5 seconds.

[0099] S206, obtaining a target hardware identifier whose connection status is abnormal from each hardware identifier;

[0100] In one embodiment, the connection status of each hardware identifier is read in the first upgrade list, and the hardware identifier with an abnormal connection status is determined as the target hardware identifier.

[0101] Among them, determining the target hardware identification and subsequent steps can be performed by the control strategy controller.

[0102] S207, deleting the target upgrade item corresponding to the target hardware identifier in the first upgrade list, and adjusting the first group identifiers of the remaining upgrade items in the first upgrade list according to the order of the group identifiers to obtain a second upgrade list;

[0103] In one embodiment, among the hardware identifiers included in the first upgrade list, a target hardware identifier whose connection status is abnormal is obtained, a target upgrade item corresponding to the target hardware identifier is deleted in the first upgrade list, and the first group identifiers of the remaining upgrade items in the first upgrade list are adjusted according to the sorting of the group identifiers to obtain a second upgrade list. The remaining upgrade items may be the upgrade items in the first upgrade list except the target upgrade items, and the second upgrade list may be a list including upgrade items whose connection status is normal.

[0104] Specifically, the target upgrade item corresponding to the target hardware identifier is deleted from the first upgrade list, and the first group identifier of the remaining upgrade items in the first upgrade list is adjusted according to the order of the group identifiers, and the method for obtaining the second upgrade list can be: obtaining the second upgrade sequence number corresponding to the first hardware identifier that is located before the target hardware identifier and adjacent to the target hardware identifier in the first upgrade list, and the third upgrade sequence number corresponding to the second hardware identifier that is located after the target hardware identifier and adjacent to the target hardware identifier, and based on the numerical relationship between the fourth upgrade sequence number of the target hardware identifier and the second upgrade sequence number and the third upgrade sequence number, adjusting the third upgrade sequence number and the fifth upgrade sequence number corresponding to each third hardware identifier located after the third upgrade sequence number to obtain the second upgrade list. Among them, the hardware identifier adjacent to the target hardware identifier is in the first upgrade list, and no other hardware identifier is included between the target hardware identifier and the target hardware identifier.

[0105] It should be noted that, if the first upgrade list includes two or more target hardware identifiers, the upgrade sequence number corresponding to the hardware identifier arranged between the two hardware identifiers and not adjacent to the target hardware identifier is determined as the fifth upgrade sequence number.

[0106] Further, based on the numerical relationship between the fourth upgrade sequence number of the target hardware identifier and the second upgrade sequence number and the third upgrade sequence number, the third upgrade sequence number and the fifth upgrade sequence numbers corresponding to each third hardware identifier located after the third upgrade sequence number are adjusted, and the method for obtaining the second upgrade list can be: if the fourth upgrade sequence number of the target hardware identifier is different from the second upgrade sequence number and the third upgrade sequence number, then after deleting the fourth upgrade sequence number, the third upgrade sequence number and the fifth upgrade sequence numbers located after the third upgrade sequence number are adjusted according to a preset step size; if the third upgrade sequence number is the same as any second upgrade sequence number, then after deleting the fourth upgrade sequence number, the third upgrade sequence number and the fifth upgrade sequence numbers located after the third upgrade sequence number are kept unchanged, wherein the preset step size can be a preset value for filling in the sequence number, for example, it can be "-1", etc. For example, the third upgrade sequence number is "3" before adjustment, and after adjusting the third upgrade sequence number based on the preset step size, the third upgrade sequence number is adjusted to "2", which can be set according to actual conditions.

[0107] For example, Figure 5 As shown, Figure 5 The hardware identifiers "ECU1", "ECU2", "ECU3", "ECU4" and "ECU5" are included, and the first upgrade serial numbers corresponding to the hardware identifiers are "1", "2", "2", "3" and "3". Since the connection status of the target hardware identifier "ECU2" is abnormal, the upgrade item corresponding to the hardware identifier is deleted from the first upgrade list, and the remaining upgrade items in the first upgrade list are adjusted to obtain a second upgrade list. Since the third upgrade serial number adjacent to the target hardware identifier is the same, there is no need to adjust the remaining upgrade items; if the second upgrade serial number and the third upgrade serial number adjacent to the target hardware identifier are different, then Figure 6 As shown, Figure 6 The fourth upgrade serial number corresponding to the target hardware identifier "ECU2" is "2", the second upgrade serial number corresponding to the second hardware identifier "ECU1" adjacent to the target hardware identifier is "1", and the third upgrade serial number corresponding to the third hardware identifier "ECU3" is "3". Therefore, after deleting the target upgrade project, the third upgrade serial number corresponding to the third hardware identifier and the fifth upgrade serial numbers arranged after the third hardware identifier in the first upgrade list are adjusted according to the preset step length. Adjust "3" to "2".

[0108] S208, determining a target hardware identifier included in the first upgrade strategy but not included in the second upgrade list, and deleting a target upgrade item corresponding to the target hardware identifier in the first upgrade strategy;

[0109] In one embodiment, after obtaining the second upgrade list, the target hardware identifiers included in the first upgrade policy and the second upgrade list are matched to determine the target hardware identifiers included in the first upgrade policy but not included in the second upgrade list, and the target hardware identifiers and target upgrade items corresponding to the target hardware identifiers are deleted from the first upgrade policy.

[0110] S209, based on the sixth upgrade sequence number in the second upgrade list, adjusting the group identifier of each hardware identifier in the first upgrade strategy to generate a second upgrade strategy;

[0111] In one embodiment, based on the sixth upgrade sequence number corresponding to each hardware identifier in the second upgrade list, the group identifiers of the remaining upgrade items in the first upgrade strategy are adjusted to generate a second upgrade strategy. The second upgrade strategy can be an execution strategy including upgrade items with a normal connection status.

[0112] Specifically, the method for adjusting the group identifier of each hardware identifier of the remaining upgrade items in the first upgrade strategy based on the sixth upgrade number can be: determine the remaining upgrade items corresponding to each sixth upgrade number in the first upgrade strategy, and adjust the group identifier in the remaining upgrade items corresponding to each sixth upgrade number. The adjustment method can be a reference method for converting the group identifier into the first upgrade number, which will not be elaborated here.

[0113] S210, based on the numerical values ​​of the group identifiers of the upgrade items in the second upgrade strategy, upgrading the electronic control units in the second upgrade strategy in sequence;

[0114] In one embodiment, based on the numerical value of the group identifier of each upgrade item in the second upgrade strategy, the electronic control units corresponding to the hardware identifiers in each upgrade item in the second upgrade strategy are upgraded in sequence from small to large. The upgrade processing can be to transmit the upgrade data package corresponding to the upgrade item to the corresponding electronic control unit according to the upgrade content included in the upgrade item, and upgrade the hardware corresponding to the hardware identifier and the software program corresponding to the software identifier of the electronic control unit according to the upgrade data package. The upgrade content can be the content of adjusting the structure of the hardware or the function of the software program, for example, it can be the adjustment of the operation mode of the gearbox, etc.

[0115] Specifically, a feasible method for upgrading each electronic control unit in sequence may be: based on the numerical value of the group identifier, the electronic control units belonging to the same group identifier are upgraded in sequence from small to large. It is understandable that another feasible method may be to upgrade each electronic control unit in sequence from large to small based on the numerical value of the group identifier and the numerical value or alphabetical order of each hardware identifier, which may be set according to actual conditions.

[0116] Further, if after parsing the connection status determined by the connection status instruction, the connection status corresponding to each hardware identifier is a normal status, then based on the numerical value of the group identifier of each upgrade item in the first upgrade strategy, each electronic control unit in the first upgrade strategy is upgraded in turn. The specific method of the upgrade process can refer to the method of upgrading the electronic control unit of each upgrade item based on the second upgrade strategy, which will not be described in detail here. It can be understood that since the connection status of the electronic control unit corresponding to the hardware identifier of each upgrade item in the first upgrade strategy is a normal status, each electronic control unit can receive the upgrade data packet, and the electronic control unit is upgraded according to the upgrade data packet, without adjusting the first upgrade strategy.

[0117] In the embodiment of the present application, by adjusting the first upgrade list corresponding to the first upgrade strategy according to the connection status of the electronic control unit in the first upgrade strategy to obtain the second upgrade list, adjusting the first upgrade strategy according to the second upgrade list to obtain the second upgrade strategy, and upgrading the electronic control unit based on the second upgrade strategy, thereby determining the connection status of the electronic control unit, removing the upgrade items corresponding to the target hardware identifier with abnormal connection status in the first upgrade strategy, so that the upgrade data packet for upgrade processing can be transmitted to the electronic control unit, thereby improving the accuracy of upgrading the electronic control unit and the safety of vehicle components. Further, according to the upgrade sequence number corresponding to the target hardware identifier with abnormal connection status, and the numerical relationship between the upgrade sequence numbers adjacent to the target hardware identifier in the first upgrade list, the first upgrade list is adjusted to obtain a second upgrade list that only includes electronic control units with normal connection status, thereby ensuring smooth and safe upgrade processing of the electronic control unit.
