Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a vehicle system upgrade method, device, electronic device, and computer-readable medium. Background Art

[0002] The vehicle control system integrates multiple electronic control units and automotive sensors to control the driving and parking of intelligent connected vehicles. In order to adapt to the upgrade of electronic control units and automotive sensors, the vehicle control system also needs to be upgraded in a timely manner. At present, when upgrading the vehicle system, the usual method is: the host computer formulates a specific upgrade process for the vehicle control system of each vehicle control unit to upgrade the vehicle control unit.

[0003] However, in practice, it is found that when the above method is used to upgrade the vehicle system, the following technical problems often occur:

[0004] A specific upgrade process is formulated for each vehicle control unit, and only one vehicle control unit can be upgraded at a time. Before upgrading the next vehicle control unit, the upgrade process and communication protocol need to be designed again, which makes it difficult to upgrade the vehicle control system of the vehicle control unit in a timely manner.

[0005] In the process of adopting technical solutions to solve the above technical problems, the following problems often occur: the storage address space of the compiled file may be discontinuous, and pointer access errors may occur when using pointers to access the compiled file, making it difficult to upgrade the vehicle control unit in a timely manner. In response to the above problems, the conventional solution is generally to fill all discontinuous storage addresses with preset data (for example, 0x00). However, the above conventional solution still has the following technical problem 2: filling all discontinuous storage addresses with preset data will increase the storage space occupied by the compiled file, thereby causing a waste of storage space.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Summary of the invention

[0023] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] Figure 1 The process 100 of some embodiments of the vehicle system upgrade method according to the present disclosure is shown. The vehicle system upgrade method comprises the following steps:

[0025] Step 101 , in response to receiving a vehicle system upgrade instruction, obtaining vehicle system upgrade information, a vehicle upgrade firmware file, and an identifier of a vehicle system to be upgraded.

[0026] In some embodiments, the execution subject of the vehicle system upgrade method may obtain the vehicle system upgrade information, the vehicle upgrade firmware file and the vehicle system identification to be upgraded from the storage terminal by wired connection or wireless connection in response to receiving the vehicle system upgrade instruction. Among them, the above-mentioned vehicle system upgrade instruction may be sent by a user terminal, representing the instruction to upgrade the vehicle control terminal. The above-mentioned user terminal may be a terminal that wants to upgrade the vehicle control terminal. The above-mentioned vehicle control terminal may be a terminal for controlling the driving of the vehicle. The above-mentioned storage terminal may be a terminal for storing the above-mentioned vehicle system upgrade information, the vehicle upgrade firmware file and the vehicle system identification to be upgraded. The above-mentioned vehicle system upgrade information may include but is not limited to at least one of the following: a system update package and an update version number. The above-mentioned system update package may be an update package for upgrading the above-mentioned vehicle control terminal. The above-mentioned update version number may be the version number corresponding to the above-mentioned system update package. The above-mentioned vehicle upgrade firmware file may be a firmware file for executing the vehicle system upgrade. The above-mentioned vehicle system identification to be upgraded can uniquely determine a vehicle control terminal.

[0027] As an example, the vehicle control terminal may be an ECU (Electronic Control Unit). The storage terminal may include but is not limited to at least one of the following: EEPROM (Electrically Erasable Programmable ROM), Flash, OTA (Over-The-Air), or cloud.

[0028] It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0029] Step 102, inspect and process the vehicle upgrade firmware file to obtain an upgrade firmware security inspection result.

[0030] In some embodiments, the execution subject may perform an inspection process on the vehicle upgrade firmware file to obtain an upgrade firmware security inspection result. The vehicle upgrade firmware file may be inspected and processed by a preset inspection algorithm to obtain an upgrade firmware security inspection result. The upgrade firmware security inspection result may be information indicating that "there is a problem with the inspection" or information indicating that "there is no problem with the inspection".

[0031] As an example, the above-mentioned preset verification algorithm may be a SHA-256 (Secure Hash Algorithm 256) algorithm.

[0032] Step 103 , in response to determining that the upgrade firmware security check result satisfies a preset security check condition, obtaining the version information of the vehicle system to be upgraded from the vehicle control terminal corresponding to the vehicle system identifier to be upgraded.

[0033] In some embodiments, the execution subject may obtain the system version information of the vehicle to be upgraded from the vehicle control terminal corresponding to the system identifier of the vehicle to be upgraded in response to determining that the upgrade firmware security inspection result satisfies the preset security inspection condition. Among them, the preset security inspection condition may be: the upgrade firmware security inspection result is information indicating that "no problem was found in the inspection". The system version information of the vehicle to be upgraded may include but is not limited to at least one of the following: system version number and system update status information. The system version number may represent the version number of the vehicle control system of the vehicle control terminal. The system update status information may be information indicating that "system update can be performed" or information indicating that "system update cannot be performed".

[0034] Step 104, in response to determining that the vehicle system version information to be upgraded meets the preset upgrade conditions, a preset upgrade instruction and vehicle system upgrade information are sent to the vehicle control terminal to perform upgrade processing on the vehicle control terminal to obtain upgrade result information.

[0035] In some embodiments, the execution subject may, in response to determining that the vehicle system version information to be upgraded satisfies a preset upgrade condition, send a preset upgrade instruction and the vehicle system upgrade information to the vehicle control terminal to upgrade the vehicle control terminal and obtain upgrade result information. The preset upgrade condition may be: the system version number included in the vehicle system version information to be upgraded is less than the update version number included in the vehicle system upgrade information, and the system update status information included in the vehicle system version information is information indicating that "system update is available". The preset upgrade instruction may indicate that the execution subject wants to upgrade the vehicle control terminal. The upgrade result information may be information indicating "successful upgrade" or information indicating "failed upgrade".

[0036] Optionally, the execution subject may further execute the vehicle system upgrade method again in response to determining that the upgrade result information satisfies a preset restart condition, wherein the preset restart condition may be that the upgrade result information is information indicating "upgrade failure".

[0037] In some optional implementations of some embodiments, the execution subject sends the vehicle system upgrade instruction and the vehicle system upgrade information to the vehicle control terminal to perform upgrade processing on the vehicle control terminal to obtain the upgrade result information, which may include the following steps:

[0038] The first step is to send the preset upgrade instruction to the vehicle control terminal to generate upgrade response information, and receive the upgrade response information from the vehicle control terminal. The preset upgrade instruction can be sent to the vehicle control terminal to generate upgrade response information through a preset communication protocol. The upgrade response information can be information indicating "successful response" or information indicating "failed response".

[0039] As an example, the preset communication protocol may be a UDS (Unified Diagnostic Services) protocol.

[0040] In the second step, in response to determining that the upgrade response information satisfies the preset response condition, the vehicle control terminal is subjected to communication inspection processing to obtain a communication inspection result. The communication inspection processing can be performed on the vehicle control terminal through the preset communication protocol to obtain the communication inspection result. The preset response condition can be that the upgrade response information is information indicating "successful response". The communication inspection result can be information indicating "passed inspection" or information indicating "failed inspection".

[0041] In the third step, in response to determining that the communication test result meets the preset communication condition, the vehicle system upgrade information is sent to the vehicle control terminal for flashing to obtain upgrade completion information. The preset communication condition may be that the communication test result is information indicating "test passed". The upgrade completion information may be information indicating "upgrade success" or information indicating "upgrade failure".

[0042] In the fourth step, in response to determining that the upgrade completion information satisfies the preset completion condition, a preset system reset instruction is sent to the vehicle control terminal to reset the vehicle control terminal, and the upgrade completion information is determined as the upgrade result information. The preset completion condition may be that the upgrade completion information is information indicating "upgrade success". The preset system reset instruction may indicate that the execution subject wants the vehicle control terminal to be reset.

[0043] In some optional implementations of some embodiments, the execution subject sends the vehicle system upgrade information to the vehicle control terminal for flashing processing to obtain upgrade completion information, which may include the following steps:

[0044] The first step is to compile the vehicle system upgrade information to obtain the vehicle system upgrade compiled information. The vehicle system upgrade compiled information includes: a storage address information sequence. In practice, the vehicle system upgrade information can be compiled by a preset compiler to obtain the vehicle system upgrade compiled information. The vehicle system upgrade compiled information can be stored in segments. Each storage address information in the storage address information sequence can represent the storage address of each segment of data in the vehicle system upgrade compiled information.

[0045] As an example, the above-mentioned preset compiler may be but is not limited to at least one of the following: GCC (GNU Compiler Collection) or LLVM (Low Level Virtual Machine).

[0046] The second step is to perform a first inspection process on the vehicle system upgrade compilation information to obtain a first inspection result. The first inspection process can be performed on the vehicle system upgrade compilation information using a preset first inspection algorithm to obtain a first inspection result. The first inspection result can be information indicating that "the first inspection passed" or information indicating that "the first inspection failed".

[0047] As an example, the above-mentioned preset first verification algorithm may be a checksum algorithm.

[0048] In the third step, in response to determining that the above-mentioned first inspection result meets the first preset inspection condition, the above-mentioned vehicle system upgrade compilation information is subjected to a second inspection process to obtain a second inspection result. Among them, in response to determining that the above-mentioned first inspection result meets the first preset inspection condition, the above-mentioned vehicle system upgrade compilation information is subjected to a second inspection process to obtain a second inspection result, which may be: in response to determining that there is discontinuity of adjacent storage address information in the storage address information sequence included in the above-mentioned vehicle system upgrade compilation information, information representing "the second inspection failed" is determined as the above-mentioned second inspection result. In response to determining that each adjacent storage address information in the storage address information sequence included in the above-mentioned vehicle system upgrade compilation information is continuous, information representing "the second inspection passed" is determined as the above-mentioned second inspection result. The above-mentioned first preset inspection condition may be that the above-mentioned first inspection result is information representing "the first inspection passed".

[0049] In the fourth step, in response to determining that the second inspection result satisfies the second preset inspection condition, the vehicle system upgrade compilation information is sent to the vehicle control terminal, and the first data inspection result is received from the vehicle control terminal. The second preset inspection condition may be that the second inspection result is information indicating that "the second inspection has passed". The first data inspection result may be information indicating that "the first data inspection has passed" or information indicating that "the first data inspection has not passed".

[0050] Step 5: In response to determining that the first data verification result satisfies the third preset verification condition, the preset completion information is determined as the upgrade completion information. The third preset verification condition may be that the first data verification result is information indicating that "the first data verification has passed". The preset completion information may be information indicating that "the upgrade is completed".

[0051] In some optional implementations of some embodiments, the execution subject sending the vehicle system upgrade compilation information to the vehicle control terminal and receiving the first data verification result from the vehicle control terminal may include the following steps:

[0052] The first step is to split the vehicle system upgrade compilation information to obtain a compilation line information sequence. Each compilation line information in the compilation line information sequence includes: a compilation line data length value. The above-mentioned splitting of the vehicle system upgrade compilation information to obtain the compilation line information sequence may be: each line of data of the vehicle system upgrade compilation information is determined as a compilation line information to obtain the compilation line information sequence. The individual compilation line information in the compilation line information sequence may be arranged in ascending order of storage address.

[0053] In the second step, for each compile line information in the above compile line information sequence, the following sending sub-steps are performed:

[0054] The first sub-step is, in response to determining that the compile line data length value included in the compile line information is greater than or equal to a preset target threshold, sending the compile line information to the vehicle control terminal, and receiving a first compile inspection result from the vehicle control terminal. The vehicle control terminal may perform a compile inspection process on the compile line information through a preset compile inspection algorithm to obtain the first compile inspection result. The first compile inspection result may be information indicating that "the compile inspection passed" or information indicating that "the compile inspection failed".

[0055] As an example, the preset target threshold may be 4100. The preset compilation check algorithm may be a CRC (Cyclic Redundancy Check) algorithm.

[0056] The second sub-step is, in response to determining that the first compilation verification result satisfies the first preset compilation condition, performing a sequence number verification process on the compilation line information to obtain a sequence number verification result. The performing a sequence number verification process on the compilation line information to obtain a sequence number verification result may be: in response to determining that the compilation line information is the last compilation line information in the compilation line information sequence, determining information indicating that "sequence number verification passed" as the sequence number verification result. In response to determining that the compilation line information is the last compilation line information in the compilation line information sequence, determining information indicating that "sequence number verification failed" as the sequence number verification result. The first preset compilation condition may be that the first compilation verification result may be information indicating that "compilation verification passed".

[0057] Therefore, it can be determined that the above-mentioned compiled line information sequences are all transmitted to the above-mentioned vehicle control terminal.

[0058] The third sub-step is, in response to determining that the above-mentioned sequence number verification result satisfies the fifth preset verification condition, sending a preset transmission exit instruction to the above-mentioned vehicle control terminal, and receiving the above-mentioned first data verification result from the above-mentioned vehicle control terminal. The above-mentioned fifth preset verification condition may be that the above-mentioned compilation line information is information indicating that "sequence number verification is passed". The above-mentioned preset transmission exit instruction may indicate that the above-mentioned execution subject wants to exit the transmission. The above-mentioned vehicle control terminal may perform the first data verification processing on the above-mentioned compilation line information sequence through the above-mentioned preset compilation verification algorithm to obtain the above-mentioned first data verification result.

[0059] Optionally, the above execution entity may further perform the following steps:

[0060] In the first step, in response to determining that the compile line data length value included in the compile line information is less than the preset target threshold, the following fusion sub-steps are performed:

[0061] The first sub-step is to merge the compile line information and the next compile line information of the compile line information to obtain merged compile line information. The compile line information and the next compile line information of the compile line information can be concatenated in the order of storage addresses to obtain the merged compile line information.

[0062] The second sub-step is to determine the above-mentioned fusion compilation line information as the compilation line information, so as to perform the above-mentioned sending step again.

[0063] In the third step, in response to determining that the first compilation check result does not meet the first preset compilation condition, the compilation line information is retransmitted, and a second compilation check result is received from the vehicle control terminal. The compilation line information is retransmitted and the second compilation check result is received from the vehicle control terminal through the preset communication protocol. The second compilation check result can be information indicating "compilation check passed" or information indicating "compilation check failed".

[0064] In the fourth step, in response to determining that the serial number verification result does not satisfy the fifth preset verification condition, the sending step is executed again.

[0065] Therefore, by adopting the above-mentioned method of sending the compiled file to the vehicle control terminal, only part of the compiled file can be read each time, and part of the compiled file can be sent to the vehicle control terminal. As a result, there is no need to read all the compiled files at once, thereby reducing memory consumption, thereby reducing the possibility of freezing due to insufficient memory or reducing memory response speed, and further, the stability and security of the vehicle control system upgrade can be improved.

[0066] Considering the problems of the above conventional solutions, facing the above technical problem 2: filling all the discontinuous storage addresses with preset data will increase the storage space occupied by the compiled file, thereby causing a waste of storage space. Combined with the existing technical status, it can be decided to adopt the following solution.

[0067] Optionally, the above execution entity may further perform the following steps:

[0068] The first step is, in response to determining that the first inspection result does not satisfy the first preset inspection condition, sending the preset system reset instruction to the vehicle control terminal to reset the vehicle control terminal.

[0069] In the second step, in response to determining that the first data inspection result does not meet the third preset inspection condition, the vehicle system upgrade compilation information is sent to the vehicle control terminal again, and the second data inspection result is received from the vehicle control terminal. The specific implementation method of generating the second data inspection result and the technical effect brought about by it can refer to step 104 in the above embodiment, which will not be repeated here. The second data inspection result can be information indicating that "the second data inspection passed" or information indicating that "the second data inspection failed".

[0070] In the third step, in response to determining that the second data verification result satisfies the fourth preset verification condition, the preset completion information is determined as the upgrade completion information. The fourth preset verification condition may be that the second data verification result is information indicating that "the second data verification has passed". The preset completion information may be information indicating that "the upgrade is completed".

[0071] Optionally, the above execution entity may further perform the following steps:

[0072] In the first step, in response to determining that the second inspection result does not satisfy the second preset inspection condition, the following filling sub-steps are performed:

[0073] The first sub-step is to perform data filling processing on the above-mentioned vehicle system upgrade compilation information to obtain vehicle system upgrade filling information.

[0074] The second sub-step is to send the vehicle system upgrade filling information to the vehicle control terminal, and receive the third data verification result from the vehicle control terminal. The specific implementation method of generating the third data verification result and the technical effect brought about by it can refer to step 104 in the above embodiment, which will not be repeated here. The third data verification result can be information indicating that "the third data verification has passed" or information indicating that "the third data verification has not passed".

[0075] The third sub-step is, in response to determining that the third data verification result satisfies a fifth preset verification condition, determining the preset completion information as the upgrade completion information. The fifth preset verification condition may be that the third data verification result is information indicating that "the third data verification has passed".

[0076] In some optional implementations of some embodiments, the execution subject performs data filling processing on the vehicle system upgrade compilation information to obtain the vehicle system upgrade filling information, which may include the following steps:

[0077] The first step is to split the vehicle system upgrade compilation information to obtain an initial fill line information sequence. The splitting of the vehicle system upgrade compilation information to obtain the initial fill line information sequence may be: determining each line of data of the vehicle system upgrade compilation information as an initial fill line information to obtain the initial fill line information sequence.

[0078] In the second step, for each initial filling row information in the above initial filling row information sequence, the following generation sub-steps are performed:

[0079] The first sub-step is to generate filling header information, filling content information and filling verification information. First, the message header information that satisfies the above-mentioned preset communication protocol can be constructed as the above-mentioned filling header information. Then, the preset filling data can be determined as the above-mentioned filling content information. Finally, the message verification information that satisfies the above-mentioned preset communication protocol can be constructed as the above-mentioned filling verification information.

[0080] The second sub-step is to merge the filling header information, the filling content information, the filling check information and the initial filling row information to obtain the target filling row information. The filling header information, the filling content information, the filling check information and the initial filling row information can be merged according to the preset communication protocol to obtain the target filling row information.

[0081] The third step is to determine the generated target filling row information as the above-mentioned vehicle system upgrade filling information.

[0082] The relevant content of step 104, as an inventive point of an embodiment of the present disclosure, solves the second technical problem mentioned in the background technology, "causing waste of storage space". Among them, the factors that lead to waste of storage space are often as follows: using preset data to fill all discontinuous storage addresses will increase the storage space occupied by the compiled file. If the above factors are solved, the effect of reducing the waste of storage space can be achieved. In order to achieve this effect, the present disclosure can split the compiled file according to the storage segments, and then construct header information and verification information for each segment with discontinuous addresses, and then fill the segment data with preset values. In this way, a compiled file with continuous storage addresses can be obtained, so that when a pointer is used to access the compiled file, the security of pointer access can be improved, so that the vehicle control unit can be upgraded in time. And, by adopting the segmented filling method, it is not necessary to fill the data of each storage address in the storage space, so that the storage space occupied by the compiled file can be reduced, and then the waste of storage space can be reduced.

[0083] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the vehicle system upgrade method of some embodiments of the present disclosure, the vehicle control system of the vehicle control unit can be upgraded in time. Specifically, the reason why it is difficult to upgrade the vehicle control system of the vehicle control unit in time is that a specific upgrade process is formulated for each vehicle control unit, and only one vehicle control unit can be upgraded at a time. Before upgrading the next vehicle control unit, the upgrade process and communication protocol need to be designed again. Based on this, the vehicle system upgrade method of some embodiments of the present disclosure, first, in response to receiving a vehicle system upgrade instruction, obtains vehicle system upgrade information, vehicle upgrade firmware files and vehicle system identification to be upgraded. Thus, the vehicle system upgrade process can be started, and the corresponding vehicle control unit can be upgraded through the vehicle system identification to be upgraded. Secondly, the above-mentioned vehicle upgrade firmware file is inspected and processed to obtain the upgrade firmware security inspection result. Thus, it can be determined whether the execution subject is in a safe state and whether the vehicle control unit can be upgraded. Then, in response to determining that the above-mentioned upgrade firmware security inspection result meets the preset security inspection condition, the vehicle system version information to be upgraded is obtained from the vehicle control terminal corresponding to the above-mentioned vehicle system identification to be upgraded. Thus, it can be determined that the above-mentioned execution can upgrade the vehicle system, and further determine whether the vehicle control unit can be upgraded. Finally, in response to determining that the above-mentioned vehicle system version information to be upgraded meets the preset upgrade conditions, the vehicle system upgrade instruction and the vehicle system upgrade information are sent to the above-mentioned vehicle control terminal to upgrade the above-mentioned vehicle control terminal and obtain the upgrade result information. Thus, it can be determined that the vehicle control unit can be upgraded, so that the vehicle system upgrade instruction and the vehicle system upgrade information can be sent to the vehicle control unit to control the upgrade of the vehicle control unit. Therefore, some vehicle system upgrade methods disclosed in the present invention can upgrade the corresponding vehicle control unit according to the identification of the vehicle control unit, and use the same upgrade process and communication protocol for different vehicle control units, so that there is no need to formulate a specific upgrade process for each vehicle control unit, and then, the vehicle control system of the vehicle control unit can be upgraded in time.
