Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
The following describes an upgrade method, an upgrade device, a vehicle and a storage medium of a vehicle controller according to embodiments of the present application with reference to the accompanying drawings. Aiming at the problems that in the related art, when a vehicle is subjected to OTA upgrading, the vehicle needs to be kept still and can not be forcedly interrupted, and the vehicle needs to be used until an upgrading task is completed, and the driving experience of a user is not facilitated, the application provides an upgrading method of the vehicle controller. Therefore, the problems that in the related art, when a vehicle is subjected to OTA upgrading, the vehicle needs to be kept stationary and can not be forcedly interrupted, the vehicle can not be used until an upgrading task is completed, driving experience of a user is not facilitated and the like are solved.
Specifically, fig. 1 is a flowchart of a method for upgrading a vehicle controller according to an embodiment of the present application.
As shown in fig. 1, the upgrade method of the vehicle controller includes the steps of:
in step S101, a pause upgrade instruction of a controller to be upgraded is received.
Optionally, in one embodiment of the present application, the upgrade condition includes: the vehicle speed is at least one of a preset vehicle speed, a vehicle gear is a preset gear, and the remaining battery power is greater than the preset power.
Specifically, in order to facilitate the user to better experience and use a more comprehensive and accurate cabin service system when driving a vehicle, the vehicle controller can update the timing, and the system after each upgrade is improved and the loophole is repaired to a certain extent so as to obtain more functions and performance improvement.
Specifically, as shown in fig. 2, when detecting that the related system function in the vehicle is not in the latest version or has not been updated for a long time, the OTA in the vehicle detects that the current application function of the vehicle is in a state to be updated, and then a box is flicked on a vehicle-mounted display in the vehicle to indicate that the user performs the vehicle update. After the user clicks the confirm upgrade button, the OTA automatically downloads an upgrade package through the network to upgrade.
Further, the OTA can pre-judge whether the current vehicle meets the upgrade condition before automatic upgrade, and upgrade the current vehicle if the current vehicle meets the upgrade condition. The upgrade condition may include at least one of a vehicle speed being a preset vehicle speed, a vehicle gear being a preset gear, and a remaining battery power being greater than a preset power.
It should be understood that if the vehicle is in a driving state, the vehicle controller is in a working state, and at this time, the controller is caused to enter a boot brushing state by performing an upgrade, so that related functions of the controller cannot be supported for normal use of the vehicle, so that in order to ensure that the vehicle can perform smoothly when receiving an upgrade task, a user needs to keep the vehicle in a standing state under the condition of confirming the upgrade, that is, a preset vehicle speed adopted in the embodiment of the present application may be 0, a preset gear may be a P gear, a preset electric quantity may be greater than 50% of an electric quantity of a storage battery, and when any one of the above conditions is met, an OTA application may implement automatic downloading of an upgrade package and a configuration file through a network to perform the upgrade when receiving the upgrade task.
Further, after the OTA application downloads the upgrade package and the configuration file, an upgrade task is generated according to the configuration file, and after the upgrade package is transmitted, the upgrade of each controller is initiated. The configuration file mainly comprises all target controllers to be upgraded, the size of an upgrade package of each controller to be upgraded, hash values, encryption modes, upgrade dependence, upgrade estimated time and the like.
Further, in the process of upgrading the vehicle, if the user needs the vehicle urgently, such as in special scenes of an intersection, a temporary stop point and the like, at this time, in order to avoid traffic safety problems such as traffic jam and the like, the user can click a forced interrupt button in an OTA application installation page, and can also send a corresponding signal to the background through a mobile phone, and the background informs the OTA application that when receiving a pause upgrading instruction of the controller to be upgraded, the current task which does not initiate installation is stopped immediately, so that the user can use the vehicle according to the current requirement, and the embarrassing scene that the vehicle cannot be used due to upgrading is avoided.
In step S102, the type of the controller to be upgraded and the current upgrade status of the controller to be upgraded are identified according to the pause upgrade instruction.
The upgrade state comprises an upgrade sub-state and a current installation progress of the controller to be upgraded. As shown in fig. 3, the upgrade sub-state of the controller to be upgraded may include the following states: idle state, upgrade package transmission state, check upgrade package state, upgrade condition detection state, pre-flush state, and flush complete state.
The controller to be upgraded does not enter the upgrading process at the moment, is still in a preparation stage, and can respond to an interrupt signal to stop the upgrading preparation action; the upgrade package transmission is that after the controller to be upgraded receives the upgrade command, the controller starts to receive the upgrade package transmission, and can respond to the interrupt signal to stop the upgrade package transmission action and return to idle; the upgrade package verification is that after the upgrade package transmission is completed, the upgrade package is verified by the to-be-upgraded controller, the upgrade package transmission action can be stopped in response to the interrupt signal, and the to-be-upgraded controller returns to idle; the upgrade condition detection is that after the upgrade package is successfully checked, the to-be-upgraded controller starts to perform condition detection before the upgrade package is installed, at the moment, the to-be-upgraded controller does not enter a boot, and the upgrade condition detection can be stopped in response to an interrupt signal and returns to idle; the pre-writing is that after the controller to be upgraded meets the upgrading conditions, the controller enters a boot state, but does not start erasing and writing operations, only performs some preparation work before writing, mainly refers to handshake with a writing end, writing and security authentication of data of a ready-to-receive upgrading packet, and the controller to be upgraded can exit upgrading in response to an interrupt signal and returns to an idle state; the refreshing is to execute erasing and writing the upgrade package data to the storage partition of the controller to be upgraded, and for the single-partition controller to be upgraded, the corresponding application data is erased, and the refreshing must be continuously completed at the moment, so that the interrupt cannot be responded; but for the double-partition controller to be upgraded, the controller can respond to the interrupt at the moment, and after exiting, the application data is read from the original partition and returns to the APP state for operation; and after the brushing is finished, the data writing is finished, and the APP operation can be switched to by resetting or active restarting.
Specifically, when the OTA application receives a command of suspending the controller to be upgraded, the OTA application immediately stops the task which is not initiated at present and inquires the type and the upgrading state of the controller to be upgraded. The type of the controller to be upgraded can be a single-partition controller and a double-partition controller. The current state of the single partition controller can be a non-refreshing state and a refreshing state, the current state of the double partition controller can be a first partition in the refreshing state, and the second partition responds to an operation instruction of the vehicle.
Optionally, in one embodiment of the present application, before identifying the current upgrade state of the controller to be upgraded according to the pause upgrade instruction, the method includes: counting the number of times of receiving the pause upgrade instruction; if the receiving times are larger than the preset times, the current upgrading state of the controller to be upgraded is identified according to the pause upgrading instruction.
The preset times may be a threshold value preset by a user, or may be a threshold value obtained by multiple simulation of a computer, which is not particularly limited herein.
Specifically, when the user goes from the driving state to the parking state, the OTA application can download and stop the upgrade status of the controller to be upgraded by itself, and after receiving the upgrade suspension instruction of the controller to be upgraded each time, the OTA application counts the number of times of receiving the upgrade suspension instruction, and if the number of times of receiving is greater than the preset number of times, for example, 5 times, the current upgrade status of the controller to be upgraded is identified according to the upgrade suspension instruction, so that repeated downloading is avoided when the upgrade is continued next time.
In step S103, when the controller to be upgraded is a single partition controller, if the current upgrade state is a non-brushing state, the controller to be upgraded is controlled to pause brushing, otherwise, the controller to be upgraded is kept in a brushing state until the controller to be upgraded finishes brushing; when the controller to be upgraded is a double-partition controller, the first partition of the controller to be upgraded is controlled to be in a brushing state, and the second partition of the controller to be upgraded is controlled to respond to the operation instruction of the vehicle.
Specifically, as shown in fig. 2, when the OTA application receives a pause upgrade instruction of the controller to be upgraded, and stops a task which is not currently initiated to be installed and queries the type and upgrade state of the controller to be upgraded, it is further determined whether an upgrade sub-state of the controller to be upgraded enters the flush.
On the one hand, if the controller to be upgraded is a single partition controller and the current upgrading state is a non-refreshing state, it is indicated that the current OTA application is still in any one of an idle state, an upgrading packet transmission state, an upgrading packet checking state, an upgrading condition detecting state or a boot pre-refreshing state, and at this time, the controller to be upgraded can exit the upgrade in response to an interrupt signal and return to the idle state. Therefore, the OTA application can send a forced stop instruction to the controller to be upgraded to control the controller to be upgraded to pause the brushing.
On the other hand, if the controller to be upgraded is a single partition controller and the current upgrade state is a flush state, that is, the current controller to be upgraded has already started to perform the operations of erasing and writing data, and the corresponding application data has already been erased, the flush must be continuously completed at this time, and the corresponding interruption cannot be performed. Therefore, if the single partition controller is in the refreshing state and the interrupt condition is not met, the normal refreshing of the controller to be upgraded is continuously controlled until the refreshing of the controller to be upgraded is completed, so that the OTA application is withdrawn from upgrading.
In still another aspect, if the controller to be upgraded is a dual-partition controller and the current upgrade state is a swipe state, then, in a scenario that the dual-partition controller is the swipe state, a forced interrupt signal sent by the OTA application can be received and responded, so that the first partition of the controller to be upgraded can be controlled to be in the swipe state, and the second partition of the controller to be upgraded is controlled to respond to an operation instruction of the vehicle to perform interrupt swipe, so that the OTA application exits from upgrading.
To sum up, for different types of controllers to be upgraded and interruptible state comparison tables in the current upgrade states where the types are located, as shown in table 1:
TABLE 1
Therefore, the embodiment of the application can control the system upgrade more effectively according to the types and the upgrade states of different controllers to be upgraded, and avoids the occurrence of upgrade abnormality.
Optionally, in one embodiment of the present application, after controlling the controller to be upgraded to suspend the brushing, the method further includes: acquiring the upgrading progress of a controller to be upgraded; and storing the upgrading progress of the controller to be upgraded to the cloud server.
Specifically, the controller to be upgraded discussed in the above embodiment can control the controller to be upgraded to pause the writing in the non-writing state of the single partition controller and the writing state of the double partition controller, and further obtain the current upgrading progress of the controller to be upgraded after the controller to be upgraded is paused writing, and store and report the upgrading progress to the cloud end so as to improve the upgrading efficiency and avoid repeated downloading.
Optionally, in one embodiment of the present application, after controlling the controller to be upgraded to suspend the brushing, the method further includes: judging whether a continuous upgrading instruction is received or not; if a continuous upgrading instruction is received and the controller to be upgraded meets the upgrading condition, acquiring the upgrading progress of the controller to be upgraded from the server; and continuously upgrading the controller to be upgraded based on the upgrading progress of the controller to be upgraded.
Specifically, as shown in fig. 4, after the user stops using the vehicle to enter the OTA application again, the OTA application detects the installation task before the interruption, if the user detects that the task which is not installed is not completed, an upgrade page is popped up to remind the user to continue installing the task, after the user confirms to resume the installation, the OTA application further inquires the task which is not completed before the interruption and acquires the upgrade progress of the controller to be upgraded through the server, so that the controller to be upgraded is continuously upgraded, and after the remaining controllers to be upgraded are completed to upgrade, the user is prompted to be installed successfully by the bullet frame, and the result is uploaded to the platform.
In summary, the embodiment of the application realizes that the vehicle can realize repeatable interruption in the upgrading process by further improving the interruption method of the vehicle upgrading in the related technology, and is not influenced by forced interruption, thereby quickly recovering good performance of the vehicle.
According to the upgrading method of the vehicle controller, after the pause upgrading instruction of the controller to be upgraded is received, the type and the current upgrading state of the controller to be upgraded are identified, and then the brushing state of the current upgrading state of the controller to be upgraded is controlled, so that a user can interrupt upgrading when the user touches an upgrading button by mistake in special scenes such as emergency use, and the like, corresponding conditions are recorded, and upgrading is continued when the upgrading conditions are waited to be met again, and therefore the practicability of the vehicle is further improved, and the driving experience of the user is met. Therefore, the problems that in the related art, when a vehicle is subjected to OTA upgrading, the vehicle needs to be kept stationary and can not be forcedly interrupted, the vehicle can not be used until an upgrading task is completed, driving experience of a user is not facilitated and the like are solved.
