Based on the hardware structure, the embodiment of the vehicle OTA upgrade checking method is provided.

Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the vehicle OTA upgrade checking method according to the present invention.

In a first embodiment, the vehicle OTA upgrade checking method comprises the following steps:

and step S10, obtaining an upgrade dependency graph of the target vehicle in the OTA upgrade of the whole vehicle.

It should be noted that the upgrade dependency graph is a schematic diagram of dependencies corresponding to a plurality of electronic devices of a vehicle when a preset vehicle OTA is upgraded, vehicles corresponding to different vehicle types correspond to different electronic devices and further correspond to different upgrade dependency graphs, and the upgrade dependency graph may be obtained by finding a relationship graph corresponding to a target vehicle to be upgraded in a preset database, or may be obtained by temporarily constructing a dependency graph after determining a corresponding electronic device, which is not limited in this embodiment.

And step S20, obtaining the upgrade path of each electronic device from the upgrade dependency relationship diagram, and tracking the upgrade path through a token.

It is understood that in the upgrade dependency graph, a plurality of electronic devices having a dependency relationship with each other are embodied as a continuous upgrade path including nodes, the upgrade path of each electronic device is obtained from the dependency graph, and can be tracked by a token, and the token may be a segment of storage space for storing a number or a character string.

And step S30, counting the accumulated value of all the tokens, comparing the accumulated value with a preset specific value, and judging whether each electronic device of the target vehicle finishes upgrading.

It should be understood that the accumulated value of all tokens can be counted by an accumulated calculation method, the preset specific value is a preset expected accumulated specific threshold, and whether each electronic device of the target vehicle is upgraded or not can be judged according to the corresponding comparison result by comparing the accumulated value with the preset specific value.

According to the scheme, the upgrading dependency graph of the target vehicle in the OTA upgrading of the whole vehicle is obtained; obtaining an upgrading path of each electronic device from the upgrading dependency relationship graph, and tracking the upgrading path through a token; the method comprises the steps of counting the accumulated values of all tokens, comparing the accumulated values with preset specific values, judging whether all electronic devices of a target vehicle are upgraded or not, determining whether all the electronic devices of the current upgrade are upgraded or not when the upgrade is finished, and avoiding omission at the moment of finishing the upgrade without post-inspection, thereby improving the upgrade inspection efficiency and speed of OTA upgrade of the whole vehicle, saving the OTA upgrade inspection time, and ensuring the comprehensiveness and accuracy of the OTA upgrade.

Further, fig. 3 is a schematic flow chart of a second embodiment of the vehicle OTA upgrade checking method according to the present invention, and as shown in fig. 3, the second embodiment of the vehicle OTA upgrade checking method according to the present invention is proposed based on the first embodiment, in this embodiment, the step S10 specifically includes the following steps:

and step S11, acquiring the precedence dependency relationship among the electronic devices of the target vehicle in the OTA upgrade of the whole vehicle.

It should be noted that, the target vehicle has a dependency relationship between the electronic devices in the whole vehicle OTA upgrade, and corresponding dependency relationship data may be acquired from the upgrade dependency relationship diagram.

And step S12, representing the precedence dependency relationship by using a line segment with an arrow, and generating an upgrade dependency relationship graph of the target vehicle in the OTA upgrade of the whole vehicle.

It can be understood that the sequence dependency relationship between the electronic devices can be represented by a line segment with an arrow, so that a schematic diagram of the dependency relationship between the electronic devices of the target vehicle in the OTA upgrade of the whole vehicle can be generated.

Further, the step S12 specifically includes the following steps:

representing the precedence dependency relationship by using a line segment with an arrow, wherein a device without the arrow end of the line segment is used as a precursor of the device without the arrow end of the line segment, the device without the arrow end of the line segment is used as a successor of the device without the arrow end of the line segment, and the OTA upgrade priority of the device without the arrow end of the line segment is prior to the device without the arrow end of the line segment;

and drawing and associating the arrow line segments to generate an upgrading dependency relationship diagram of the target vehicle in the OTA upgrading of the whole vehicle.

It should be understood that the precedence dependency relationship between the devices is represented by a line segment with an arrow, the device without the arrow end of the line segment is called a front driver of the device without the arrow end, the device without the arrow end of the line segment is called a back driver of the device without the arrow end, the OTA upgrade priority of the device without the arrow end of the line segment is prior to the device without the arrow end of the line segment, and after drawing and associating the line segments of the arrow, an upgrade dependency relationship graph of the target vehicle in OTA upgrade of the whole vehicle can be generated.

According to the scheme, the sequence dependency relationship among the electronic devices of the target vehicle in the OTA upgrading of the whole vehicle is obtained; representing the precedence dependency relationship by using a line segment with an arrow, and generating an upgrade dependency relationship graph of the target vehicle in the OTA upgrade of the whole vehicle; the method can generate a detailed upgrade dependency graph, ensures the upgrade precision, and improves the speed and efficiency of the whole OTA upgrade.

Further, fig. 4 is a schematic flow chart of a third embodiment of the vehicle OTA upgrade checking method according to the present invention, and as shown in fig. 4, the third embodiment of the vehicle OTA upgrade checking method according to the present invention is proposed based on the first embodiment, in this embodiment, the step S20 specifically includes the following steps:

step S21, obtaining the upgrade path of each electronic device from the upgrade dependency graph, and assigning a token to each upgrade path from a virtual starting point.

It should be noted that, path extraction may be performed from the upgrade dependency graph, so as to obtain upgrade paths of the electronic devices, where the upgrade paths corresponding to different electronic devices may be the same or different, and generally, a token may be allocated to each upgrade path from a virtual starting point, where the virtual starting point is a point with a preset virtual point as a starting point.

And step S22, tracking and recording the upgrade path through the token.

It can be understood that the token can pass through each upgrade node of the path along the path to finally reach the virtual end point, so that the upgrade path tracking recording function can be realized.

In this embodiment, by the above scheme, the upgrade path of each electronic device is obtained from the upgrade dependency graph, and a token is allocated to each upgrade path from a virtual starting point; the upgrading paths are tracked and recorded through the token, the upgrading states of all the upgrading paths can be tracked and recorded, the problem of omission at the moment of finishing upgrading is avoided, and the upgrading checking efficiency and speed of OTA upgrading of the whole vehicle are improved.

Further, fig. 5 is a schematic flow chart of a fourth embodiment of the vehicle OTA upgrade checking method according to the present invention, and as shown in fig. 5, the fourth embodiment of the vehicle OTA upgrade checking method according to the present invention is proposed based on the third embodiment, in this embodiment, before the step S22, the vehicle OTA upgrade checking method further includes the following steps:

step S221, connecting a virtual start point to the head end of each upgrade path, and connecting a virtual end point to the tail end of each upgrade path, where the virtual start point points to all device nodes without predecessors, and the virtual end point is pointed to by all device nodes without successors.

It should be noted that before the upgrade path is tracked and recorded, a virtual start point needs to be connected to the head end of each upgrade path, and a virtual end point needs to be connected to the tail end of each upgrade path, that is, the virtual start point points to all device nodes without predecessors, and the virtual end point points to device nodes without successors.

In a specific implementation, starting from a virtual starting point, a token (which may be understood as a segment of storage space that may store a number or a character string) is allocated for each upgrade path; the token passes through each upgrading node of the upgrading path along the upgrading path and finally reaches a virtual terminal.

According to the scheme, the head end of each upgrading path is connected with the virtual starting point, the tail end of each upgrading path is connected with the virtual terminal point, the virtual starting point points to all device nodes without predecessors, and the virtual terminal point is pointed by all device nodes without successors, so that the upgrading paths can be traced more clearly and conveniently, and the OTA upgrading speed and efficiency of the vehicle are improved.

Further, fig. 6 is a schematic flow chart of a fifth embodiment of the vehicle OTA upgrade checking method according to the present invention, and as shown in fig. 6, the fifth embodiment of the vehicle OTA upgrade checking method according to the present invention is proposed based on the first embodiment, in this embodiment, the step S30 specifically includes the following steps:

and step S31, recording the value of all tokens entering any upgrading path and entering each section of arrowed line segment, generating an accumulated token entering record, recording the value of all tokens entering any upgrading path and leaving each section of arrowed line segment, and generating an accumulated token record.

It should be noted that, when each token passes through each segment along any upgrade path, the values of the entering segment and the leaving segment are accumulated into the token record and accumulator, and by recording the values of all the tokens entering into each segment of the arrowed segment and leaving from each segment of the arrowed segment, the corresponding accumulated token record and accumulated token record can be obtained.

And step S32, taking the cumulative token record and the cumulative token record as a token-contained cumulative value, wherein the values in the cumulative token record and the cumulative token record are pairwise cancelled when equal.

It will be appreciated that the running token record and the running token record may be referred to as running tokens, and in actual practice, the token record and the totalizer keep only one running token throughout.

In a specific implementation, the values in the cumulative incoming token record and the cumulative outgoing token record are pairwise cancelled when they are equal, that is, all tokens in all paths, and at each time when a token enters and leaves a segment with an arrow, the two times (entering segment and leaving segment) the token has a value that satisfies the property of pairwise cancellation, for example, for the exclusive or calculation, as shown in fig. 7, fig. 7 is a schematic diagram illustrating the pairwise cancellation of the exclusive or of the token values in the vehicle OTA upgrade checking method of the present invention, and the equal values can be pairwise cancelled; for example, for the summation calculation, as shown in fig. 8, fig. 8 is a schematic diagram illustrating pairs of positive and negative cancellation of token values in the vehicle OTA upgrade checking method of the present invention, and equal and opposite values can be cancelled in pairs.

Correspondingly, for a line segment with an arrow (from an end without an arrow to an end with an arrow) passed by the token, the value of the token before entering the line segment is given by the node without the arrow after the upgrading of the node is finished; the value after the token leaves the line segment and the value before the token enters the line segment satisfy the property of pair-wise cancellation according to a specific accumulative calculation method.

And step S33, comparing the accumulated value with a preset specific value, and judging whether each electronic device of the target vehicle finishes upgrading.

It should be understood that by comparing the accumulated value with a preset specific value, a corresponding comparison result can be generated, and whether each electronic device of the target vehicle is upgraded can be judged according to the comparison result.

Further, the step S33 specifically includes the following steps:

comparing the accumulated value with a preset specific value to generate a comparison result;

when the comparison result is that the accumulated value is equal to a preset specific value, judging that each electronic device of the target vehicle finishes upgrading;

and when the comparison result is that the accumulated value is not equal to a preset specific value, judging that the upgrading of each electronic device of the target vehicle is not completed.

It can be understood that, if the accumulated value of all tokens in the token record and the accumulator is equal to a certain specific value, it is generally 0, and of course, it may also be other values, which is not limited in this embodiment, and when the comparison result is that the accumulated value is equal to a preset specific value, it may be necessary to insufficiently determine that the whole upgrade process is normal; if the number of the nodes is not equal to the preset specific value, the upgrading is inevitably incomplete, and some or some nodes are not upgraded successfully; the effect that whether all the electronic devices of the upgrade are completely upgraded can be determined without checking afterwards is achieved when the upgrade is finished.

According to the scheme, the accumulated token entering record is generated by recording the value of all tokens entering any upgrading path and entering each section of line segment with an arrow, the value of all tokens entering any upgrading path and leaving each section of line segment with an arrow is recorded, and the accumulated token record is generated; taking the accumulated token record and the accumulated token record as accumulated values with tokens, wherein the values in the accumulated token record and the accumulated token record are subjected to pair cancellation when being equal; and comparing the accumulated value with a preset specific value, judging whether each electronic device of the target vehicle finishes upgrading, determining whether all the electronic devices of the upgrading finish upgrading or not at the same time of finishing upgrading without checking afterwards, avoiding the missing problem existing at the moment of finishing upgrading, improving the upgrading checking efficiency and speed of the OTA upgrading of the whole vehicle, saving the time of OTA upgrading checking, and ensuring the comprehensiveness and accuracy of the OTA upgrading.

Correspondingly, the invention further provides a vehicle OTA upgrade checking device.

Referring to fig. 9, fig. 9 is a functional block diagram of a first embodiment of the OTA upgrade checking device for vehicle according to the present invention.

In a first embodiment of the OTA upgrade inspection apparatus for a vehicle according to the present invention, the OTA upgrade inspection apparatus for a vehicle includes:

the obtaining module 10 is configured to obtain an upgrade dependency graph of the target vehicle in the OTA upgrade of the entire vehicle.
