Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to an electronic oil pump OTA upgrade method, device, equipment and computer storage medium. Background Art

[0002] At present, "software-defined cars" has become the development trend of automobiles, and the complexity of automobile software has also increased greatly. It is difficult to provide users with the best experience by only upgrading at 4S stores to fix software failures and update personalized customization needs. Therefore, in new energy vehicles, ECU is required to have OTA (Over-The-Air technology) function. Through OTA technology, software-related problems can be fixed without recalls, and new functions can be pushed to vehicles and vehicle performance can be improved.

[0003] Oil-cooled motors cool the stator and rotor of the motor directly through oil, and have high heat dissipation efficiency; therefore, oil-cooled motors have higher power density. Currently, new energy vehicles widely use oil-cooled motors as drive motors. Oil-cooled motors cool the stator and rotor of the motor through oil, so oil-cooled electric drives usually have electronic oil pumps (EOP); considering the energy loss and NVH performance of the entire vehicle, the motor controller generally controls the speed of the electronic oil pump according to the actual cooling requirements of the electric drive, and the electronic oil pump only communicates with the motor controller (MCU). Therefore, the current common practice is that the motor controller is connected to the oil pump through (internal) private CAN communication (or LIN communication), that is, in the vehicle CAN network, there is only a motor controller node, and the oil pump is the slave node of the motor controller.

[0004] The common practice of OTA upgrade of electric drive system is: TBOX obtains software package from OTA platform, conducts diagnostic communication with MCU through gateway, and upgrades MCU program. Because the oil pump is not in the vehicle CAN network, TBOX cannot communicate directly with the electronic oil pump; at the same time, the communication protocol between TBOX and MCU and the communication protocol between MCU and EOP may be different (for example, the communication protocol between TBOX and MCU may be high-speed CANFD, and the communication protocol between MCU and EOP may be slower LIN), so the electronic oil pump cannot be updated and upgraded through vehicle OTA. Summary of the invention

The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0042] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0043] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0044] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0045] At present, "software-defined cars" has become the development trend of automobiles, and the complexity of automobile software has also increased greatly. It is difficult to provide users with the best experience by only upgrading 4S stores to repair software failures and update personalized customization needs. Therefore, in new energy vehicles, ECU is required to have OTA (Over-The-Air technology) function. Through OTA technology, software-related problems can be repaired without recalls, and new functions can be pushed to vehicles and vehicle performance can be improved. Oil-cooled motors directly cool the stator and rotor of the motor through oil, and have high heat dissipation efficiency; therefore, oil-cooled motors have higher power density. At present, new energy vehicles widely use oil-cooled motors as drive motors. Oil-cooled motors cool the stators and rotors of the motors through oil, so oil-cooled electric drives usually have electronic oil pumps (EOPs); considering the energy loss and NVH performance of the vehicle, the motor controller generally controls the speed of the electronic oil pump according to the actual cooling requirements of the electric drive, and the electronic oil pump only communicates with the motor controller. Therefore, the current common practice is that the motor controller is connected to the oil pump through (internal) private CAN communication (or LIN communication), that is, in the vehicle CAN network, there is only a motor controller node, and the oil pump is the slave node of the motor controller. The current common practice for OTA upgrades of electric drive systems is: TBOX obtains the software package from the OTA platform, conducts diagnostic communication with the motor controller (MCU) through the gateway, and upgrades the MCU program. Because the oil pump is not in the vehicle CAN network, TBOX cannot communicate directly with the electronic oil pump; at the same time, considering the cost factor, the communication protocol between TBOX and MCU and the communication protocol between MCU and EOP may be different (for example, the communication protocol between TBOX and MCU may be the high-speed CANFD communication protocol, and the communication protocol between MCU and EOP may be the slower LIN communication protocol), so the electronic oil pump cannot be updated and upgraded through vehicle OTA.

[0046] Figure 1 The flowchart of the first embodiment of the electronic oil pump OTA upgrade method provided by the present application is shown, and the method is executed by the MCU. Figure 1 As shown, the method comprises the following steps:

[0047] Step S110: When the TBOX obtains the MCU software upgrade package from the OTA platform, based on the erase memory instruction corresponding to the MCU software upgrade package sent by the TBOX, it is determined whether the MCU software upgrade package is the electronic oil pump software upgrade package corresponding to the electronic oil pump to obtain a judgment result.

[0048] Among them, the MCU software upgrade package is a general term for the electronic oil pump upgrade software and the motor controller (MCU) upgrade software. The MCU software upgrade package contains at least one of the electronic oil pump upgrade software and the MCU upgrade software. The instructions sent by TBOX to the MCU are all fixed programs in the OTA upgrade program. According to the relevant information in the erase memory instruction, it can be determined whether the MCU software upgrade package is the electronic oil pump software upgrade package (electronic oil pump upgrade software) corresponding to the electronic oil pump.

[0049] Specifically, when TBOX obtains the MCU software upgrade package from the OTA platform, the MCU receives the erase memory instruction corresponding to the MCU software upgrade package sent by TBOX, and based on the erase memory instruction, determines whether the MCU software upgrade package is the electronic oil pump software upgrade package corresponding to the electronic oil pump, and obtains a judgment result.

[0050] Step S120: When the judgment result is yes, the electronic fuel pump upgrade instruction set including the memory erase instruction of the electronic fuel pump software upgrade package sent by the TBOX is forwarded to the electronic fuel pump for OTA upgrade.

[0051] The electronic oil pump upgrade instruction set includes multiple instructions for implementing the electronic oil pump upgrade. Different instructions contain different data for the electronic oil pump upgrade. The multiple instructions in the electronic oil pump upgrade instruction set can be sent to the electronic oil pump in sequence according to a preset order, or can be sent selectively according to the response result of the electronic oil pump.

[0052] Specifically, when the MCU software upgrade package is the electronic oil pump software upgrade package corresponding to the electronic oil pump, the MCU receives the electronic oil pump upgrade instruction set including the erase memory instruction of the electronic oil pump software upgrade package sent by TBOX, and forwards the electronic oil pump upgrade instruction set to the electronic oil pump, so that the electronic oil pump is OTA upgraded according to the electronic oil pump upgrade instruction set.

[0053] The technical solution of this embodiment can realize OTA upgrade of the electronic oil pump of the whole vehicle through the MCU, thereby improving the upgrade efficiency and convenience of the electronic oil pump.

[0054] In an optional manner, the erase memory instruction includes: a target memory address. Based on the erase memory instruction corresponding to the MCU software upgrade package sent by the TBOX, the step of determining whether the MCU software upgrade package is an electronic oil pump software upgrade package corresponding to the electronic oil pump further includes:

[0055] Obtain the target memory address in the erase memory instruction.

[0056] If the target memory address is the memory address of the electronic oil pump, the MCU software upgrade package is determined to be the electronic oil pump software upgrade package corresponding to the electronic oil pump; otherwise, the MCU software upgrade package is determined not to be the electronic oil pump software upgrade package corresponding to the electronic oil pump.

[0057] The target memory address is the memory address MemoryAddress in the erase memory instruction. In addition to the memory address MemoryAddress, the erase memory instruction also includes: the erase memory size MemorySize. According to the specific value of the target memory address, it can be determined whether the MCU software upgrade package is the electronic oil pump software upgrade package corresponding to the electronic oil pump.

[0058] In an optional manner, the method further includes:

[0059] The electronic oil pump upgrade instruction set sent by the TBOX is received through a first communication protocol.

[0060] Wherein, the first communication protocol is: a communication protocol adapted to instruction transmission between the TBOX and the MCU.

[0061] In an optional manner, the step of forwarding the electronic oil pump upgrade instruction set to the electronic oil pump includes:

[0062] The electronic oil pump upgrade instruction set is forwarded to the electronic oil pump through a second communication protocol.

[0063] Wherein, the second communication protocol is: a communication protocol adapted to the instruction transmission between the MCU and the electronic oil pump.

[0064] It should be noted that when the MCU receives any instruction in the electronic oil pump upgrade instruction set sent by the TBOX, in order to send the instruction to the electronic oil pump for execution, the first forwarding function "Transform_Tbox2Eop()" is used to convert the instruction that satisfies the first communication protocol into an instruction that satisfies the second communication protocol. For example, the first communication protocol is the CANFD communication protocol, and the second communication protocol is the LIN communication protocol.

[0065] Figure 2 The flowchart of the second embodiment of the electronic oil pump OTA upgrade method provided by the present application is shown, and the method is executed by the MCU. Figure 2 As shown, the method comprises the following steps:

[0066] Step S210: When the TBOX obtains the MCU software upgrade package from the OTA platform, based on the erase memory instruction corresponding to the MCU software upgrade package sent by the TBOX, it is determined whether the MCU software upgrade package is the electronic oil pump software upgrade package corresponding to the electronic oil pump to obtain a judgment result.

[0067] Step S220: When the judgment result is yes, receiving the electronic oil pump upgrade instruction set including the erase memory instruction of the electronic oil pump software upgrade package sent by the TBOX; wherein the electronic oil pump upgrade instruction set includes: erase memory instruction, download request instruction, data transmission instruction and exit transmission instruction.

[0068] Step S230: forwarding the erase memory instruction sent by the TBOX to the electronic oil pump, so as to receive a first instruction response result generated by the electronic oil pump executing the erase memory instruction and forwarding it to the TBOX.

[0069] Among them, the specific process of the electronic oil pump executing the erase memory instruction (UDS 0x31 service) is:

[0070] ①When MCU receives the erase memory instruction sent by TBOX, it stores the erase memory data corresponding to the erase memory instruction into the data buffer;

[0071] ② According to the second communication protocol between the MCU and the electronic oil pump, the MCU sends a diagnostic instruction to make the electronic oil pump enter the programming mode.

[0072] ③ The electronic oil pump receives the diagnostic instruction to enter the programming mode sent by the MCU and checks whether the electronic oil pump meets the conditions for entering the programming mode; if so, the electronic oil pump enters the programming mode and feeds back the diagnostic instruction response result to the MCU;

[0073] ④The MCU receives the response result that the electronic oil pump successfully enters the programming mode, calls the forwarding function Transform_Tbox2Eop(), and forwards the erase memory data in the data buffer buffer to the electronic oil pump; the electronic oil pump receives the erase memory instruction sent by the MCU, executes the erase memory instruction, and feeds back the first instruction response result to the MCU; the MCU stores the received relevant data into the data buffer buffer, and calls the forwarding function Transform_Eop2Tbox() to report the first instruction response result of the erase memory to TBOX.

[0074] Step S240: when the first instruction response result is a successful response, forwarding the download request instruction generated by the TBOX to the electronic oil pump, so as to receive a second instruction response result generated by the electronic oil pump executing the download request instruction and forwarding it to the TBOX.

[0075] Among them, the specific process of the electronic oil pump executing the download request instruction (UDS 0x34 service) is as follows:

[0076] ①MCU sets the electronic oil pump program upgrade flag EOP_Program to 1;

[0077] ②The MCU stores the data corresponding to the received download request instruction into the data buffer, calls the forwarding function Transform_Tbox2Eop(), and forwards the data in the buffer to the electronic oil pump;

[0078] ③ The electronic oil pump receives the download request instruction sent by the MCU and checks whether the electronic oil pump meets the download request conditions; if so, the electronic oil pump responds to the download request instruction and feeds back the second instruction response result of the download request instruction to the MCU.

[0079] ④The MCU stores the received relevant data into the data buffer, and calls the forwarding function Transform_Eop2Tbox() to report the second instruction response result requested for download to TBOX.

[0080] Step S250: when the second instruction response result is a successful response, forwarding the data transmission instruction generated by the TBOX to the electronic oil pump, so as to receive a third instruction response result generated by the electronic oil pump executing the data transmission instruction and forwarding it to the TBOX.

[0081] Among them, the specific process of the electronic oil pump executing the data transmission instruction (UDS 0x36 service) is as follows:

[0082] ① TBOX receives the second command response from MCU and sends a data transmission command (UDS 0x36 service) to MCU. After receiving the data transmission command, MCU determines that the oil pump program is upgraded because the oil pump upgrade flag bit EOP_Program is 1;

[0083] ②The MCU stores the data corresponding to the received data transmission instruction into the data buffer, calls the forwarding function Transform_Tbox2Eop(), and forwards the data in the buffer to the electronic oil pump;

[0084] ③ The electronic oil pump receives the data sent by the MCU, and feeds back the third instruction response result generated by executing the data transmission instruction to the MCU;

[0085] ④The MCU stores the received relevant data into the data buffer, and calls the forwarding function Transform_Eop2Tbox() to report the third instruction response result to TBOX.

[0086] Step S260: When the third instruction response result is a successful response, the exit transmission instruction generated by the TBOX is forwarded to the electronic oil pump, so as to receive a fourth instruction response result generated by the electronic oil pump executing the exit transmission instruction and forward it to the TBOX.

[0087] The specific process of the electronic oil pump executing the exit transmission instruction (UDS 0x37 service) is as follows:

[0088] ①TBOX detects that data transmission is complete according to the response result of the fourth instruction, and sends a request to exit transmission instruction (UDS 0x37 service) to MCU;

[0089] ②After the MCU receives the exit transmission instruction, because the oil pump upgrade flag EOP_Program is 1, the MCU stores the data corresponding to the received exit transmission instruction into the data buffer buffer, calls the forwarding function Transform_Tbox2Eop(), and forwards the data in the data buffer buffer to the electronic oil pump.

[0090] ③ The electronic oil pump receives and responds to the request to exit the transmission instruction, and feeds back the fourth instruction response result generated by executing the exit transmission instruction to the MCU.

[0091] ④The MCU stores the received relevant data into the data buffer, and calls the forwarding function Transform_Eop2Tbox() to report the fourth instruction response result to TBOX.

[0092] Step S270: When the fourth instruction response result is a successful response, it is determined that the OTA upgrade of the electronic oil pump is completed.

[0093] When the fourth instruction response result is a successful response, the MCU determines that the OTA upgrade of the electronic oil pump is successfully completed.

[0094] The technical solution of this embodiment further clarifies the specific process of OTA upgrade of the electronic oil pump, thereby enabling OTA upgrade of the electronic oil pump of the entire vehicle through the MCU, thereby improving the upgrade efficiency and convenience of the electronic oil pump.

[0095] In an optional manner, the electronic oil pump upgrade instruction set further includes: an integrity check instruction; the method further includes:

[0096] When the fourth instruction response result is a successful response, the integrity check instruction generated by the TBOX is forwarded to the electronic oil pump, so as to receive a fifth instruction response result generated by the electronic oil pump executing the integrity check instruction and forward it to the TBOX.

[0097] When the fifth instruction response result is a successful response, it is determined that the electronic oil pump software upgrade package is complete.

[0098] Among them, the specific process of the electronic oil pump executing the integrity check instruction (UDS 0x31 service) is as follows:

[0099] ①TBOX sends integrity check command (UDS 0x31 service) to MCU;

[0100] ②After the MCU receives the integrity check instruction, because the oil pump upgrade flag EOP_Program is 1, the MCU stores the data corresponding to the received integrity check instruction into the data buffer buffer, calls the forwarding function Transform_Tbox2Eop(), and forwards the data in the data buffer buffer to the electronic oil pump.

[0101] ③ The electronic oil pump receives the data in the data buffer and performs integrity check on the downloaded data; if the check passes, the fifth instruction response result generated by executing the integrity check instruction is fed back to the MCU.

[0102] ④MCU stores the received data into the data buffer, and calls the forwarding function Transform_Eop2Tbox() to report the successful response result to TBOX to complete the integrity check of the electronic oil pump software upgrade package.
