Detailed Description
For the purposes of brevity and explanation, the principles of the present application are described herein with reference primarily to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of systems for remotely unlocking a vehicle firewall, methods of remotely unlocking a vehicle firewall, and computer-readable storage media, and that these same or similar principles may be implemented therein, with any such variations not departing from the true spirit and scope of the present application.
According to an aspect of the present application, a system for remotely unlocking a firewall of a vehicle is provided. As shown in fig. 1, the system 10 includes a parameter configuration unit 101, an instruction generation unit 102, a data storage unit 103, a data communication unit 104, and an instruction pushing unit 105. Wherein the parameter configuration unit 101 is configured to receive unlocking parameters regarding a vehicle firewall of one or more vehicles. The system 10 may remotely unlock a variety of different vehicles, each of which may have different unlocking parameters, and thus may need to be configured separately depending on the vehicle to be unlocked by the system. Upon receiving the configuration parameters for different vehicles, the system 10 may unlock the vehicles according to a predetermined schedule, for example, may collectively unlock all of the vehicles configured with their unlocking parameters at a time, and may unlock some of them. In some embodiments of the present application, the trial administrator needs to configure the items (parameters) in the background that require the remote monitoring module to unlock in a specified format before using the remote monitoring module to unlock the firewall as described in more detail below. The unlocking parameters may include at least a portion of an ECU ID, a request ID, an unlocking channel number, a bus protocol, a bus baud rate, a security level, a number of bytes of a seed.
The instruction generating unit 102 is configured to generate an unlocking instruction according to the unlocking parameter and transmit the unlocking instruction. The unlocking instruction can be directly sent to the vehicle to be unlocked, and then the instruction execution unit arranged in the vehicle executes the unlocking instruction, so that the firewall of the vehicle is unlocked. The invention does not limit the form of the unlocking instruction, and only needs to bear the necessary content capable of unlocking the firewall of the vehicle. In some examples, the unlock instruction even does not claim itself to be an instruction, and is not different in form from other interactive data, and the vehicle end can recognize this type of unlock instruction from the content and use it to unlock the vehicle firewall.
The data storage unit 103 is configured to receive and store the unlock instruction. The unlocking instruction generated by the instruction generating unit 102 is not necessarily used for unlocking the firewall of the vehicle immediately, and the data storage unit 103 may temporarily store the unlocking instruction and issue the unlocking instruction at an appropriate time.
The data communication unit 104 is configured to receive an unlock request. If the firewall of the vehicle needs to be unlocked, the vehicle may send an unlocking request to the system 10, specifically, to the data communication unit 104, and then the system 10 issues an unlocking instruction according to the unlocking request. For example, a remote monitoring module, described in detail below, may upload an unlock request to the system 10 according to a remote transmission protocol.
The instruction pushing unit 105 is configured to read the unlocking instruction stored in the data storage unit 103 according to the unlocking request and push the unlocking instruction. Some examples of the invention can issue corresponding unlocking instructions (including unlocking processes and unlocking parameters) for firewalls of different vehicle types, and can automatically unlock after a remote monitoring module such as described in detail below receives the unlocking instructions, which greatly improves the convenience and efficiency of the test. In some examples of the invention, the push may be delivered over a public network that may have access to multiple vehicles, such as the internet, a metropolitan area network, a local area network, and the like.
In some embodiments of the present application, the data communication unit 104 is further configured to receive a response status, where the response status indicates a receiving situation, an executing situation of the unlocking instruction pushed by the instruction pushing unit 105. The receiving condition may include receiving time of the unlocking instruction, and the executing condition may include bus data on the test vehicle acquired after unlocking and a state of the test vehicle.
In some embodiments of the present application, the system 10 further comprises a recording unit configured to record the following: the time when the instruction generation unit 102 sends the unlocking instruction, the time when the instruction push unit 105 reads the unlocking instruction from the data storage unit 103, and the time when the unlocking instruction indicated in the response state received by the data communication unit 104 is received. Specifically, the recording unit records the time of the configuration issued by the instruction generating unit 102 in the background, and writes the configuration content that needs to be unlocked into the data storage unit 103, waiting for the instruction pushing unit 105 to read. And records the time read by the remote monitoring module after the instruction pushing unit 105 reads the configuration.
In some embodiments of the present application, the instruction pushing unit 105 is further configured to check the unlocking request, and push the unlocking instruction after the check is passed. Specifically, for example, the unlocking request may be generated according to an identification mark of the remote monitoring module 201, and thus the instruction pushing unit 105 may identify the identification mark.
Some examples of the invention unlock based on the remote monitoring module, which greatly reduces the cost of the test tool and can realize mass use. Some examples of the invention can remotely issue corresponding unlocking flows and related parameters to a remote monitoring module aiming at firewalls of different vehicle types, and the remote monitoring module can actively unlock the firewall and collect vehicle bus data after the vehicle is started after receiving configuration, monitor the vehicle state and upload the related data to a recording unit of the system.
In some embodiments of the present application, as shown in fig. 2, compared to the system 10 shown in fig. 1, the system 20 for remotely unlocking a firewall of a vehicle further includes a remote monitoring module 201, and other unit modules of the system 20 may be configured according to corresponding unit modules in the system 10. The remote monitoring module 201 is provided at the vehicle end, and may be configured to perform the following items: and generating an unlocking request according to the identity identification mark of the remote monitoring module 201, sending the unlocking request, receiving an unlocking instruction pushed by the instruction pushing unit 105, and sending the receiving condition and the execution condition of the unlocking instruction at the vehicle end.
In some examples, after the remote monitoring module 201 is powered on, the remote monitoring module 201 may upload an unlock request including a module number of the remote monitoring module 201 to the system 20 for verification according to a remote transmission protocol. After the verification is completed, the system 20 will push an unlocking instruction including the unlocking parameter to the remote monitoring module 201 in the issued list. The remote monitoring module 201 may feed back the receiving condition and the execution condition of the unlocking instruction according to the remote transmission protocol. The recording unit of system 20 may record the time at which remote monitoring module 201 obtains the configuration.
In some examples, the remote monitoring module 201 may actively unlock the firewall after the vehicle is started during the test process, collect the test vehicle bus data after unlocking, monitor the test vehicle status, and transmit the data to the system 20.
The system for remotely unlocking the vehicle firewall provided by some examples of the invention solves the problem of data acquisition of the test vehicle after the firewall is started, so that the management efficiency of a test field is improved for vehicle test field managers. The remote monitoring module arranged at the vehicle end can automatically unlock different vehicle types, acquire vehicle bus data in the test process and monitor the vehicle, so that the automation degree and the test efficiency of the test process are improved. Meanwhile, under any test condition, as long as a network signal exists, firewall unlocking flows of different vehicle types can be issued remotely.
In some embodiments of the present application, the parameter configuration unit 101 is further configured to group one or more vehicles, and the instruction generation unit 102 is further configured to generate the unlocking instruction with respect to the group. In some examples of the invention, the trial administrators may group vehicles in the background that need to unlock the firewall by project. After grouping is completed, test managers can issue projects in batches and also can issue vehicles in the projects in a single vehicle mode, and therefore flexible control over the test vehicles is achieved.
According to another aspect of the present application, a method of remotely unlocking a vehicle firewall is provided. As shown in fig. 3, the method 30 of unlocking a vehicle firewall includes the following steps. The method comprises the steps of receiving unlocking parameters of a vehicle firewall of one or more vehicles in step S301, generating unlocking instructions according to the unlocking parameters in step S302, and pushing the unlocking instructions to the one or more vehicles remotely in step S303.
The method 30 receives in step S301 unlocking parameters regarding a vehicle firewall for one or more vehicles, from which a plurality of different vehicles can be remotely unlocked. Each vehicle may have different unlocking parameters and thus need to be configured separately according to the vehicle to be unlocked. After receiving the configuration parameters of different vehicles, the vehicles may be unlocked according to a predetermined schedule, for example, all the vehicles configured with the unlocking parameters may be collectively unlocked at a time, and some of the vehicles may be unlocked. In some embodiments of the present application, before unlocking the firewall, the test administrator needs to configure the items (parameters) that need to be unlocked by the remote monitoring module in the background according to a specified format. The unlocking parameters may include at least a portion of an ECU ID, a request ID, an unlocking channel number, a bus protocol, a bus baud rate, a security level, a number of bytes of a seed.
The method 30 generates an unlock instruction according to the unlock parameter in step S302. The unlocking instruction can be directly sent to the vehicle to be unlocked, and then the instruction execution unit arranged in the vehicle executes the unlocking instruction, so that the firewall of the vehicle is unlocked. The invention does not limit the form of the unlocking instruction, and only needs to bear the necessary content capable of unlocking the firewall of the vehicle. In some examples, the unlock instruction even does not claim itself to be an instruction, and is not different in form from other interactive data, and the vehicle end can recognize this type of unlock instruction from the content and use it to unlock the vehicle firewall.
The method 30 remotely pushes an unlock instruction to one or more vehicles in step S303. Some examples of the invention can issue corresponding unlocking instructions (including unlocking processes and unlocking parameters) for firewalls of different vehicle types, and can perform unlocking autonomously after the remote monitoring module receives the unlocking instructions, which greatly improves the convenience and efficiency of the test. In some examples of the invention, the push may be delivered over a public network that may have access to multiple vehicles, such as the internet, a metropolitan area network, a local area network, and the like.
According to another aspect of the present application, a method of remotely unlocking a vehicle firewall is provided. As shown in fig. 4, the method 40 of unlocking a vehicle firewall includes the following steps. The method comprises the steps of receiving unlocking parameters of a vehicle firewall of one or more vehicles in step S401, generating unlocking instructions according to the unlocking parameters and storing in step S402, receiving unlocking requests in step S403, and reading the unlocking instructions according to the unlocking requests and pushing in step S404.
The method 40 receives in step S401 unlocking parameters regarding a vehicle firewall of one or more vehicles, from which a plurality of different vehicles can be remotely unlocked. Each vehicle may have different unlocking parameters and thus needs to be configured separately according to the vehicle to be unlocked. After receiving the configuration parameters of different vehicles, the vehicles may be unlocked according to a predetermined schedule, for example, all the vehicles configured with their unlocking parameters may be unlocked collectively at a time, and a part of them may be unlocked. In some embodiments of the present application, before unlocking the firewall, the test administrator needs to configure, in the background, the items that need to be unlocked by the remote monitoring module according to a specified format. The unlocking parameters may include at least a portion of an ECU ID, a request ID, an unlocking channel number, a bus protocol, a bus baud rate, a security level, a number of bytes of a seed.
The method 40 generates an unlock instruction according to the unlock parameter and stores it in step S402. The unlocking instruction can be directly sent to the vehicle to be unlocked, and then the instruction execution unit arranged in the vehicle executes the unlocking instruction, so that the firewall of the vehicle is unlocked. The invention does not limit the form of the unlocking instruction, and only needs to bear the necessary content capable of unlocking the firewall of the vehicle. In some examples, the unlock instruction even does not claim itself to be an instruction, and is not different in form from other interactive data, and the vehicle end can recognize this type of unlock instruction from the content and use it to unlock the vehicle firewall. In addition, the generated unlocking instruction is not necessarily used for unlocking the firewall of the vehicle immediately, so that the unlocking instruction can be temporarily stored and issued at a proper time.
The method 40 receives an unlock request in step S403. If the firewall of the vehicle needs to be unlocked, the vehicle can send an unlocking request, and then an unlocking instruction is issued according to the unlocking request. For example, an in-vehicle module, such as a remote monitoring module, may upload an unlock request to an unlock server system according to a remote transmission protocol.
The method 40 reads the unlocking instruction according to the unlocking request and pushes the unlocking instruction in step S404. Some examples of the invention can issue corresponding unlocking instructions (including unlocking processes and unlocking parameters) for firewalls of different vehicle types, and can perform unlocking autonomously after the remote monitoring module receives the unlocking instructions, which greatly improves the convenience and efficiency of the test. In some examples of the invention, the push may be delivered over a public network that may have access to multiple vehicles, such as the internet, a metropolitan area network, a local area network, and the like.
In some embodiments of the present application, the method 40 further comprises the steps of: and receiving a response state from the vehicle, wherein the response state indicates the receiving condition and the executing condition of the unlocking instruction pushed by the unlocking server system. The receiving condition may include receiving time of the unlocking instruction, and the executing condition may include bus data on the test vehicle acquired after unlocking and a state of the test vehicle.
In some embodiments of the present application, the method 40 further comprises the steps of: the time at which the unlocking instruction is generated in step S402, the time at which the unlocking instruction is read in step S404, and the reception time of the unlocking instruction indicated by the response state received in the above step are recorded.
In some embodiments of the present application, the unlocking request is also checked in step S404, and the unlocking instruction is pushed after the check is passed. Specifically, for example, the unlocking request may be generated according to an identification flag of the remote monitoring module, and thus the identification flag may be recognized in step S404.
Some examples of the invention unlock based on the remote monitoring module, which greatly reduces the cost of the test tool and can realize mass use. Some examples of the invention can remotely issue corresponding unlocking flows and related parameters to a remote monitoring module aiming at firewalls of different vehicle types, and the remote monitoring module can actively unlock the firewall and collect vehicle bus data after the vehicle is started after receiving configuration, monitor the vehicle state and upload the related data to a recording unit of the system.
