Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a power-off method for a vehicle controller according to an embodiment of the present invention, where the method is applicable to a situation where the vehicle controller is powered off, and the method may be executed by a power-off device for the vehicle controller, where the device may be implemented in the form of software and/or hardware, where the hardware may be an electronic device, and optionally, the electronic device may be a mobile terminal, a server, and the like.
As shown in fig. 1, the method of this embodiment specifically includes the following steps:
and S110, when the target vehicle receives a power-off request, closing each asynchronous functional component according to the preset closing time length corresponding to each asynchronous functional component.
The target vehicle may be any vehicle equipped with a vehicle controller. The power-down request may be a request generated by the target vehicle to turn off the vehicle controller, may be in the form of a control instruction, or the like. The asynchronous functional component may be a functional module of the vehicle-mounted software that runs asynchronously. The preset shutdown duration may be a preset duration that allows shutdown of each asynchronous functional component.
Specifically, when the user wants to turn off the vehicle controller of the target vehicle, a power-off request may be generated and issued by a vehicle key, a vehicle-mounted system, or the like. When the target vehicle receives the power-off request, the preset closing duration corresponding to each asynchronous functional component can be obtained, and the asynchronous functional components are closed in sequence. In the process of closing each asynchronous functional component, the time spent for closing each asynchronous functional component does not exceed the preset closing time length corresponding to the asynchronous functional component.
It should be noted that, if the time taken to turn off a certain asynchronous functional component is less than or equal to the preset turn-off duration corresponding to the asynchronous functional component, it may be determined that the asynchronous functional component is turned off. If the preset closing time corresponding to the asynchronous functional component is reached and the asynchronous functional component is not completely closed, the closing operation of the asynchronous functional component can be skipped in order to ensure the subsequent closing operation of the vehicle controller.
And S120, after the closing processing of each asynchronous functional component is completed, closing an operating system of the target vehicle and an external power device of the target vehicle.
The operating system may be an operating system of a vehicle controller. The external power device may be an external power driving chip of the target vehicle or the like.
Specifically, after each asynchronous functional component is shut down, the operating system of the target vehicle may be further shut down. After the operating system is shut down, the external power devices of the target vehicle may be shut down.
Optionally, the asynchronous functional component includes at least one of a COM component and an NVM component, and may further include other asynchronous functional components.
And S130, after the operating system and the external power device are closed, closing a main relay of the target vehicle.
The main relay may be a device in the vehicle controller as a main switch.
Specifically, after the asynchronous functional components, the operating system and the external power device are turned off, it may be determined that a period of time has elapsed between the current time and the time when the power-off request is received, and then the main relay may be turned off to complete power-off of the vehicle controller of the target vehicle.
According to the technical scheme of the embodiment of the invention, when the target vehicle receives the power-off request, the power-off processing is carried out on each asynchronous functional component according to the preset power-off duration corresponding to each asynchronous functional component, after the power-off processing of each asynchronous functional component is completed, the operating system of the target vehicle is turned off, the external power device of the target vehicle is turned off, and the main relay of the target vehicle is turned off after the operating system and the external power device are turned off, so that the problem that the vehicle controller cannot be safely powered off under different power-off working conditions in the power-off process is solved, the power-off process of the vehicle controller is delayed, and the safe power-off technical effect of the vehicle controller is ensured.
Example two
Fig. 2 is a schematic flow chart of a power-down method of a vehicle controller according to a second embodiment of the present invention, and reference is made to the technical solution of this embodiment for a manner of performing a shutdown process on each asynchronous functional component according to a preset shutdown duration corresponding to each asynchronous functional component in this embodiment. The same or corresponding terms as those in the above embodiments are not explained in detail herein.
As shown in fig. 2, the method of this embodiment specifically includes the following steps:
s210, when the target vehicle receives a power-off request, for each asynchronous functional component, if the component closing time length of the asynchronous functional component is detected to be smaller than the preset closing time length corresponding to the asynchronous functional component, or the asynchronous functional component is not closed completely in the preset closing time length, closing the next asynchronous functional component.
The component shutdown duration may be time actually spent in shutdown processing of the asynchronous functional component.
Specifically, when the target vehicle receives a power-off request, the shutdown processing is performed for each asynchronous functional component, and when the asynchronous functional component performs the shutdown processing, the component shutdown duration of the asynchronous functional component is recorded. If the closing time length of the component is less than the preset closing time length, the asynchronous functional component is closed within the preset closing time length, and the next asynchronous functional component can be closed. If the asynchronous functional component is not completely closed within the preset closing duration, the problem that the asynchronous functional component cannot directly execute the closing operation is indicated, and at this time, in order to ensure that the vehicle controller can be normally powered off, the asynchronous functional component can be skipped to be closed, and the next asynchronous functional component is closed.
Illustratively, the preset closing time of the asynchronous function component a is 2 seconds, the asynchronous function component a is closed, if the component closing time of the asynchronous function component a is less than 2 seconds, or the closing time of the asynchronous function component a reaches 2 seconds, the asynchronous function component a still does not complete the closing operation, so that the asynchronous function component a is closed, and the next asynchronous function component is closed.
Optionally, if it is detected that the component shutdown duration of the asynchronous functional component is shorter than the preset shutdown duration corresponding to the asynchronous functional component, and the asynchronous functional component is not completely shutdown within the preset shutdown duration, the shutdown processing on the asynchronous functional component is continuously executed.
Specifically, if it is detected that the component closing time length of the asynchronous functional component is shorter than the preset closing time length corresponding to the asynchronous functional component, the asynchronous functional component may be considered to be still in the component closing process, at this time, the closing processing of the asynchronous functional component may be continuously performed, and the component closing time may be continuously recorded.
And S220, if the next asynchronous functional component does not exist, determining that the closing processing of each asynchronous functional component is completed.
Specifically, if the next asynchronous functional component does not exist, it is indicated that the shutdown processing has been performed on each asynchronous functional component in sequence. The shutdown operation has been performed for these asynchronous functional components regardless of whether all of these asynchronous functional components have completed the shutdown operation and are in a shutdown state. In this case, it can be determined that the shutdown processing by each asynchronous functional component is completed.
And S230, after the closing processing of each asynchronous functional component is finished, closing an operating system of the target vehicle and closing an external power device of the target vehicle.
And S240, after the operating system and the external power device are closed, closing a main relay of the target vehicle.
According to the technical scheme of the embodiment, when the target vehicle receives the power-off request, for each asynchronous functional component, if the component closing time length of the asynchronous functional component is detected to be smaller than the preset closing time length corresponding to the asynchronous functional component or the asynchronous functional component is not closed completely within the preset closing time length, closing processing is performed on the next asynchronous functional component, and if the next asynchronous functional component does not exist, it is determined that the closing processing of each asynchronous functional component is completed, so that the time control is performed on the process of closing the asynchronous functional component. After the asynchronous functional components are closed, the operating system of the target vehicle is closed, the external power device of the target vehicle is closed, and after the operating system and the external power device are closed, the main relay of the target vehicle is closed, so that the problem that the components are damaged due to the fact that the asynchronous functional components are immediately powered off when the vehicle controller is powered off is solved, the power-off process of the vehicle controller is delayed, and the safe power-off technical effect of the vehicle controller is guaranteed.
EXAMPLE III
Fig. 3 is a schematic flow chart of a power-down method of a vehicle controller according to a third embodiment of the present invention, in this embodiment, a timer is added to monitor a total time length for turning off each asynchronous functional component, and for each asynchronous functional component, a manner of detecting a working state of the asynchronous functional component according to a preset period may refer to the technical solution of this embodiment. The same or corresponding terms as those in the above embodiments are not explained in detail herein.
As shown in fig. 3, the method of this embodiment specifically includes the following steps:
and S310, starting a timer when the target vehicle receives a power-off request.
Wherein, the timer is configured with a preset overtime duration. The timer can be a timing device for accurately controlling time, and can be a hardware timer, such as a hardware watchdog and the like. The preset timeout period may be a preset time taken from the acceptance of the power-down request to the possible closing of the main relay.
Specifically, when the target vehicle receives a power-off request, in order to monitor the shutdown processing procedure of each asynchronous functional component within the preset shutdown duration, a timer including a preset timeout duration may be started.
And S320, aiming at each asynchronous functional component, detecting the working state of the asynchronous functional component according to a preset period.
The preset period may be a period duration for polling to detect the operating state of the asynchronous functional component. The operating state may be used to describe the current state of the asynchronous functional component, for example: an on state and an off state.
Specifically, when the asynchronous functional modules are closed, the operating state of the asynchronous functional modules may be periodically detected during the closing process of each asynchronous functional module, so as to determine whether the asynchronous functional modules have completed the closing process.
It should be noted that the preset periods corresponding to different asynchronous functional components may be the same or different, and the setting of the specific period time may be set according to actual requirements, which is not specifically limited in this embodiment.
S330, if the working state of the asynchronous functional component is detected to be a closed state within the preset closing duration corresponding to the asynchronous functional component, or the working state of the asynchronous functional component is detected to be an open state when the preset closing duration is reached, closing the next asynchronous functional component.
Specifically, when each asynchronous functional component is closed, the working state of the asynchronous functional component is detected according to a preset period. If the working state of the asynchronous functional component is detected to be the closed state periodically within the preset closing duration corresponding to the asynchronous functional component, it indicates that the asynchronous functional component is closed within the preset closing time, and the next asynchronous functional component can be closed. If the working state of the asynchronous functional component is detected to be still in an open state periodically when the preset closing duration is reached, the problem that the asynchronous functional component cannot directly execute the closing operation is indicated, and at the moment, in order to ensure that the vehicle controller can be powered off normally, the asynchronous functional component can be skipped to be closed, and the next asynchronous functional component is closed.
And S340, if the next asynchronous functional component does not exist, determining that the closing processing of each asynchronous functional component is completed.
Specifically, if the next asynchronous functional component does not exist, it is indicated that the shutdown processing has been performed on each asynchronous functional component in sequence. The shutdown operation has been performed for these asynchronous functional components regardless of whether all of these asynchronous functional components have completed the shutdown operation and are in a shutdown state. In this case, it can be determined that the shutdown processing by each asynchronous functional component is completed.
And S350, after the closing processing of each asynchronous functional component is finished, closing an operating system of the target vehicle and closing an external power device of the target vehicle.
And S360, after the operating system and the external power device are closed, if the execution time length between the starting time of the timer and the current time is less than the preset overtime length, executing the reset operation of the timer, and closing the main relay of the target vehicle.
The starting time may be the time for starting the timer, and the execution duration may be the duration between the starting time and the current time, and is used for measuring the starting duration of the timer.
Specifically, after the operating system and the external power device are turned off, the execution duration between the starting time of the timer and the current time is less than the preset timeout duration, which indicates that the asynchronous functional components are turned off, and the time spent by the operating system and the external power device is within the preset range. In this case, the reset operation may be performed on the timer for the next use, and the main relay is turned off to complete the power-off of the vehicle controller of the target vehicle.
For example, if the timer is a hardware watchdog timer, the reset operation of the timer may be a hardware watchdog feeding operation.
And S370, if the execution time length between the starting time of the timer and the current time reaches the preset timeout time length, the timer is not reset, and the operation of starting the timer is returned to be executed.
Specifically, when the execution time length between the starting time of the timer and the current time reaches the preset timeout time length, the fact that the reset operation is not executed on the timer indicates that the shutdown of the operating system and the external power device is not completed within the preset timeout time length means that the reset operation cannot be executed on the timer. In this case, the vehicle controller is reset, and the power-off operation is performed again, that is, the operations of starting the timer, turning off the asynchronous functional components, turning off the operating system, turning off the external power device, and the like are performed in return.
It should be noted that, if the number of times of powering down again exceeds a preset threshold, for example: 1 time, 2 times and the like, prompt information can be generated and sent to a user of the target vehicle, so that the user can autonomously check whether the power-off problem of the vehicle controller is influenced.
It should be further noted that, in the embodiment of the present invention, a first re-monitoring for periodic detection and timeout monitoring of each asynchronous functional component is adopted, and a second re-monitoring for monitoring all operations before the main relay is turned off by using a timer is also adopted. Through the double monitoring, the condition that the main relay is directly powered off in the running process of the asynchronous functional components under different working conditions can be avoided, and the power-off safety of the vehicle controller is improved. And, can avoid through the first heavy monitoring because a certain asynchronous function subassembly power-off abnormity and can't carry out the problem of the power down of vehicle controller, can monitor the whole power down time in the first heavy monitoring through the second heavy monitoring, guarantee vehicle controller safety power down.
As an alternative implementation of the foregoing embodiments, fig. 4 is a schematic flow chart of another power-down method for a vehicle controller according to a third embodiment of the present invention. The same or corresponding terms as those in the above embodiments are not explained in detail herein.
In a real-time control system for a vehicle, powering down a vehicle controller typically includes: the method comprises the steps of closing power drive, closing a communication protocol stack, closing each asynchronous functional component, closing an operating system, closing an external power device, closing a main relay and the like.
In the power-down process, before the operating system is shut down, the shutdown process of the partially asynchronous functional component is executed asynchronously under the scheduling of the control system. During the closing process, various power-off working conditions of the target vehicle are difficult to cover, and the risk that the vehicle controller cannot be safely powered off exists.
As shown in fig. 4, the power-off method of the vehicle controller specifically includes the following steps:
the first step is as follows: after the vehicle controller receives the power-off request, a hardware watchdog timer is started, a hardware watchdog timeout period (preset timeout duration) is set according to the normal power-off duration of the system, and the whole power-off process is monitored overtime.
The second step is that: and carrying out periodic timing monitoring on each asynchronous operation in the power-down process before the operating system is closed. According to the characteristics of each asynchronous module (asynchronous functional component), a module overtime monitoring threshold (preset closing time length) is set. And polling the closing state of the asynchronous module in the periodic task, if the asynchronous module is closed before the corresponding overtime monitoring threshold is overtime, resetting the overtime monitoring threshold, and starting the subsequent closing process of the asynchronous module. If the corresponding overtime monitoring threshold value is overtime and the asynchronous module is not closed, the asynchronous module is not waited to be closed, the closing process of the asynchronous module is considered to be abnormal, and the subsequent closing process of the asynchronous module is directly started.
Alternatively, the asynchronous module may be a COM component or an NVM component, etc. The periodic tasks may include: reading the closing state of the asynchronous module, accumulating the running period count value of the asynchronous module, judging whether the asynchronous module is closed or the closing time length of the asynchronous module exceeds an overtime monitoring threshold, if so, closing the next asynchronous component, and if not, returning to the step of reading the closing state of the asynchronous module.
The third step: and in the power-off operation after the operating system and the external power device are closed, adding a hardware watchdog feeding operation. If the task closed by the monitoring asynchronous module is abnormal, the hardware watchdog feeding operation can not be carried out within the overtime period of the hardware watchdog. At this time, the vehicle controller is reset, and the power-off process is executed again. If the watchdog feeding operation is carried out within the hardware watchdog overtime period, the main relay can be closed, and the power-off is completed.
According to the technical scheme of the embodiment, when the target vehicle receives the power-off request, the timer is started, so that the whole power-off process is monitored through the timer. And detecting the working state of the asynchronous functional component according to a preset period aiming at each asynchronous functional component, if the working state of the asynchronous functional component is detected to be a closed state within a preset closing duration corresponding to the asynchronous functional component, or the working state of the asynchronous functional component is detected to be an open state when the preset closing duration is reached, closing the next asynchronous functional component, and if the next asynchronous functional component does not exist, determining that the closing processing of each asynchronous functional component is completed, so as to periodically detect whether each asynchronous functional component is closed. After the closing processing of each asynchronous functional component is finished, the operating system of the target vehicle is closed, the external power device of the target vehicle is closed, after the operating system and the external power device are closed, if the execution time length between the starting time of the timer and the current time is less than the preset timeout time length, executing a reset operation of the timer and turning off a main relay of the target vehicle, if an execution duration between a start time of the timer and a current time reaches a preset timeout duration, the reset operation of the timer is not executed, the operation of starting the timer is returned to be executed, the problem of device damage caused by immediate power-off when the vehicle controller is powered off is solved, the problem that the whole power-off process cannot be monitored is solved, the power-off process of the vehicle controller is delayed, and the technical effect of ensuring the safe power-off of the vehicle controller is achieved.
