Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, system, device and medium for identifying switch status, and a vehicle. Background Technology

[0002] With the increasing level of automotive electronics, the electronic and electrical architecture of vehicles is developing towards centralization, intelligence, and electrification. The number of control units on the vehicle is gradually decreasing, while the functional integration is greatly improving, which puts forward higher requirements for the sleep and wake-up management mechanism of each controller unit.

[0003] The switching status of electronic appliances in a vehicle is often associated with the sleep / wake-up state transition of the corresponding controller. When the controller is in sleep mode, it cannot collect the switching status of external electronic appliances in real time. Inaccurate acquisition and recognition of switching status can cause the controller's logic functions to fail to be triggered or to be triggered erroneously, which can lead to the controller being woken up erroneously or unable to sleep. This not only affects the static power consumption of the entire vehicle, but also greatly affects the overall functional performance of the vehicle. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a switch state identification method, system, device and medium, and a vehicle to solve the technical problems existing in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a switch state identification method, comprising the following steps:

[0006] The switch level signal of the target device is acquired before the controller goes into sleep mode, wherein the switch level signal is used to characterize the switch state of the target device, and the target device and the controller are located in the same vehicle;

[0007] The switch level signal is subjected to a first anti-jitter processing, and the switch level signal after the first anti-jitter processing is subjected to a first classification and identification.

[0008] The switch level signal identified in the first category is stored in a pre-determined or real-time determined target storage area. After the controller wakes up from sleep, the switch state of the target device is identified based on the switch level signal stored in the target storage area.

[0009] In one embodiment of the present invention, after the controller wakes up from sleep, the process of identifying the switching state of the target device based on the switching level signal stored in the target storage area includes:

[0010] After the controller wakes up from sleep, it performs a second anti-jitter processing on the switch level signals stored in the target storage area, and performs a second classification recognition on the switch level signals after the second anti-jitter processing, and transmits the switch level signals after the second classification recognition to the controller, so that the controller can identify the switching state of the target device according to the switch level signals after the second classification recognition.

[0011] In one embodiment of the present invention, the process of performing a first anti-jitter processing on the switch level signal includes:

[0012] The switching level signal is filtered using a pre-determined or real-time determined filtering algorithm to perform a first anti-jitter processing on the switching level signal; if the switching level signal maintains the same state within a preset time of anti-jitter filtering, the switching state of the switching level signal is considered valid, and the level signal is updated to overwrite the previously acquired level signal.

[0013] In one embodiment of the present invention, the filtering algorithm includes: a filtering algorithm determined based on a low-pass filter, a filtering algorithm determined based on a high-pass filter, and a filtering algorithm determined based on a band-pass filter.

[0014] In one embodiment of the present invention, the target storage area determined in advance or in real time includes: the non-volatile storage space of the controller.

[0015] The present invention also provides a switch state recognition system, the system comprising:

[0016] The acquisition module is used to acquire the switching level signal of the target device before the controller goes into sleep mode, wherein the switching level signal is used to characterize the switching state of the target device, and the target device and the controller are located in the same vehicle;

[0017] The filtering module is used to perform a first anti-jitter processing on the switch level signal acquired by the level acquisition module;

[0018] A switch identification module is used to perform a first classification identification on the switch level signal after the first anti-shake processing is completed;

[0019] The switch state storage module is used to store the switch level signal after the first classification identification into a target storage area that is determined in advance or in real time.

[0020] The control module is used to control the controller to trigger corresponding functional logic based on the switch level signal stored in the target storage area after the controller wakes up from sleep.

[0021] The present invention also provides a switch state identification device, comprising:

[0022] Controller;

[0023] And, a computer-readable medium storing instructions, which, when executed by the controller, cause the device to perform the switch state recognition method as described above.

[0024] The present invention also provides a computer-readable medium having instructions stored thereon, the instructions being loaded by a controller and executed as described in any of the above-described switch state recognition methods.

[0025] The present invention also provides a vehicle including a switch status recognition device as described above.

[0026] In one embodiment of the present invention, the vehicle includes at least one of the following: a fuel vehicle and a new energy vehicle.

[0027] As described above, the present invention provides a method, system, device, and medium for identifying switch states, and a vehicle, which has the following beneficial effects: First, the switch level signal of the target device is acquired before the controller goes into sleep mode. Then, the switch level signal is subjected to a first anti-jitter processing, and the switch level signal after the first anti-jitter processing is subjected to a first classification identification. Next, the switch level signal after the first classification identification is stored in a pre-determined or real-time determined target storage area. After the controller wakes up from sleep mode, the switch state of the target device is identified based on the switch level signal stored in the target storage area. The switch level signal is used to characterize the switch state of the target device, and the target device and the controller are located in the same vehicle. Therefore, by storing the switch level signal, the present invention enables the controller to accurately identify the switch state of vehicle devices based on the stored switch level signal during the controller's sleep / wake-up state, and to implement corresponding control logic functions according to the switch level signal. This solves the problem of the current controller misidentifying switch state transitions and thus erroneously triggering functions when acquiring different switch level signals during sleep / wake-up states. Furthermore, after the controller wakes up, the present invention also eliminates the problem of misidentifying transitions by delaying the function control for a period of time, i.e., waiting for filtering to complete before performing function control. Furthermore, the controller of this invention can recognize user on / off requests even during sleep mode, improving the intelligence of the control logic and enhancing the efficiency of function control. Simultaneously, it avoids erroneous function triggering during the sleep-wake process, thus forming a more effective and accurate functional closed loop. Attached Figure Description

[0034] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0035] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0036] like Figure 1 As shown, Figure 1 The diagram illustrates a flowchart of a current switch state recognition scheme. First, the switch state of the electronic device before the controller goes into sleep mode is collected, denoted as switch state 1. Then, after the controller is woken up, the switch state of the corresponding electronic device is collected again, denoted as switch state 2. In a typical controller switch state acquisition model, to improve the robustness of switch state acquisition, the acquired switch states are usually debouncing. Because the debouncing process requires a certain filtering time, the controller cannot obtain the true switch state immediately upon wakeup. Therefore, the controller receives a non-true switch state (switch state 2) upon wakeup, and only receives the true switch state (switch state 1) after filtering. This discrepancy can cause the controller to detect a switch state jump, thus interpreting the external switch state as a change, falsely triggering functions or causing certain functions to malfunction, affecting the controller's performance after wakeup. In short, the current defects in switch recognition mainly fall into the following two categories:

[0037] 1. When the controller is in sleep mode, if the relevant scenario changes, such as a switch inside the vehicle being pressed, causing a change in the controller's digital port data, the controller, being in sleep mode, cannot record the real-time change. Therefore, when the controller is powered on again and woken up, it cannot recognize that the digital port status has changed, resulting in information loss. Consequently, the function cannot be triggered immediately after the controller is woken up, significantly impacting the driving experience.

[0038] 2. When the controller wakes up, before initialization is complete, the collected states of each port are generally assumed to be the default states. However, the state of the controller at the last moment before sleep is not necessarily the default state. Since the default state is obtained first after wake-up, and then the actual state is collected, state transitions may occur, leading to false triggering of functions. For example, if the hood is open before the vehicle goes into sleep mode, the controller will initially assume the hood is in the default state 0 during initialization after the vehicle wakes up. After the switch data collection is completed, it will identify the actual state of the hood switch as 1. This will cause a transition in the collected switch state, which is often associated with the controller's sleep / wake-up process. Misidentification can lead to the false wake-up of other network nodes, affecting the overall vehicle power consumption. Furthermore, for switches related to drive modules, such as the wiper return switch, if the switch state cannot be accurately identified immediately upon power-up, the wiper module may think the wiper return switch is not in the returned position, causing the wipers to rotate once. This can further affect other functions, such as the washer spray system.

[0039] Therefore, in current controller switch acquisition models, there is often a problem of lost user switch operations when the controller is in sleep mode. That is, the controller cannot recognize the changes in switch state during sleep, leading to significant user complaints. On the other hand, at the moment the controller wakes up, it is often impossible to obtain the accurate switch state immediately, which can easily lead to false triggering of functions and greatly reduce system robustness.

[0040] Therefore, in order to solve the above-mentioned defects, in an exemplary embodiment of the present invention, this embodiment provides a switch state recognition method, such as... Figure 2 As shown, Figure 2 A schematic flowchart of a switch state identification method according to an embodiment of the present invention is shown. The method includes the following steps:

[0041] S210, acquire the switching level signal of the target device before the controller goes into sleep mode, wherein the switching level signal is used to characterize the switching state of the target device, and the target device and the controller are located in the same vehicle. As an example, in this embodiment, electronic devices in the vehicle can be used as the target device, such as, but not limited to, the vehicle's windshield wiper motor, the vehicle's hood, etc.

[0042] S230, performs first anti-jitter processing on the switch level signal, and performs first classification and identification on the switch level signal after the first anti-jitter processing;

[0043] S240, the switch level signal identified after the first classification is stored in a pre-determined or real-time determined target storage area, and after the controller wakes up from sleep, the switch state of the target device is identified based on the switch level signal stored in the target storage area. As an example, in this embodiment, the pre-determined or real-time determined target storage area includes: the controller's non-volatile storage space.

[0044] According to the above description, in this embodiment, the process of identifying the switching state of the target device based on the switching level signal stored in the target storage area after the controller wakes up from sleep may include: performing a second anti-jitter processing on the switching level signal stored in the target storage area after the controller wakes up from sleep, performing a second classification recognition on the switching level signal after the second anti-jitter processing, and transmitting the second-classified switching level signal to the controller so that the controller can identify the switching state of the target device according to the second-classified switching level signal. In this embodiment, the first anti-jitter processing and the second anti-jitter processing represent anti-jitter processing at two different times, and the first classification recognition and the second classification recognition represent classification recognition at two different times. As an example, the methods of the first anti-jitter processing and the second anti-jitter processing in this embodiment can be the same or different; similarly, the methods of the first classification recognition and the second classification recognition in this embodiment can be the same or different.

[0045] According to the above description, in an exemplary embodiment, the process of performing a first anti-jitter processing on the switch level signal includes: filtering the switch level signal using a pre-determined or real-time determined filtering algorithm to perform the first anti-jitter processing on the switch level signal; if the switch level signal maintains the same state within a preset time of anti-jitter filtering, the switch state of the switch level signal is considered valid, and the level signal is updated to overwrite the previously acquired level signal. Furthermore, the process of performing a second anti-jitter processing on the switch level signal includes: filtering the switch level signal using a pre-determined or real-time determined filtering algorithm to perform the second anti-jitter processing on the switch level signal; if the switch level signal maintains the same state within a preset time of anti-jitter filtering, the switch state of the switch level signal is considered valid, and the level signal is updated to overwrite the previously acquired level signal. Specifically, the filtering algorithm in this embodiment can be set according to actual conditions. For example, the filtering algorithm in this embodiment can be a filtering algorithm determined based on a low-pass filter, a filtering algorithm determined based on a high-pass filter, or a filtering algorithm determined based on a band-pass filter. It can also be a filtering algorithm determined according to other methods or other filters.

[0046] Therefore, this embodiment, by storing the switch level signals, enables the controller to accurately identify the switching state of vehicle components based on the stored switch level signals during sleep / wake-up states. It then implements corresponding control logic functions according to the switch level signals, thus solving the problem of current controllers misidentifying switch state transitions and triggering functions when collecting different switch level signals during sleep / wake-up states. Furthermore, this embodiment eliminates the problem of misidentifying transitions by delaying function control for a period of time after the controller wakes up, i.e., waiting for filtering to complete before performing function control. Moreover, this embodiment's controller can also recognize user switch request operations during sleep, improving the intelligence of the control logic and enhancing function control efficiency. Simultaneously, it avoids erroneous function control triggering during the sleep / wake-up process, thus forming a more effective and accurate functional closed loop.

[0047] In another exemplary embodiment of the present invention, such as Figure 3 As shown, this embodiment provides a method for identifying switch state changes during controller sleep / wake-up, including the following steps:

[0048] After the controller is powered on and woken up, the switching level signal of the target device is acquired;

[0049] The acquired switch level signal is filtered using a filtering algorithm to debouncing the switch level.

[0050] The system checks whether filtering is complete. If filtering is complete, it performs a first classification and identification on the filtered switch level signal. If filtering is incomplete, it continues to filter the acquired switch level signal using the filtering algorithm.

[0051] The switch level after the first classification is identified is transmitted to the controller so that the controller can execute the corresponding functional logic and trigger the corresponding function according to the first classification result;

[0052] Determine whether the controller will enter sleep mode; if the controller will enter sleep mode, store the switch level signal identified in the first category into the controller's non-volatile memory space, which will not be lost when the controller enters sleep mode; otherwise, if the controller will not enter sleep mode for the time being, continue to collect the switch level signal of the target device and iterate through the above process again.

[0053] Determine whether the switch level signal has been successfully stored; if it has, wait for the controller to enter sleep mode; otherwise, if it has not been successfully stored, store the switch level signal identified in the first category into the controller's non-volatile memory space.

[0054] Therefore, in this embodiment, when the user wakes up the vehicle, the controller can obtain the effective switch state in the first instance through the optimized switch sampling model and implement the corresponding control function according to the switch state. Furthermore, it can also identify the user's switch request operation during sleep mode, improving the intelligence of the control logic and enhancing the efficiency of function control. At the same time, it avoids the controller from erroneously triggering function control during the sleep-wake process, thus forming a more effective and accurate functional closed loop. Therefore, this embodiment can consider storing the switch state in real time, not only before the controller goes into sleep mode; but also after the controller wakes up, the function control can be delayed for a period of time, i.e., waiting for the filtering to complete before performing function control, which can also eliminate the problem of misidentified jumps.

[0055] In summary, this invention provides a method for identifying switch states. First, it acquires the switch-level signal of the target device before the controller enters sleep mode. Then, it performs a first anti-jitter processing on the switch-level signal and a first classification identification on the anti-jitter processed switch-level signal. Next, it stores the first-classified switch-level signal in a pre-determined or real-time determined target storage area. After the controller wakes up from sleep mode, it identifies the switch state of the target device based on the switch-level signal stored in the target storage area. The switch-level signal characterizes the switch state of the target device, and the target device and controller are located in the same vehicle. Therefore, by storing the switch-level signal, this method allows the controller to accurately identify the switch state of vehicle devices based on the stored switch-level signal during sleep / wake-up states, and to implement corresponding control logic functions according to the switch-level signal. This solves the problem of misidentifying switch state transitions and thus erroneously triggering functions when the controller acquires different switch-level signals during sleep / wake-up states. Furthermore, this method also eliminates the problem of misidentifying transitions by delaying function control for a period of time after the controller wakes up, i.e., waiting for filtering to complete before performing function control. Furthermore, this method allows the controller to recognize user on / off requests even during sleep mode, enhancing the intelligence of the control logic and improving functional control efficiency. Simultaneously, it prevents erroneous functional control triggering during the sleep-wake process, thus forming a more effective and accurate functional closed loop.

[0056] like Figure 4 As shown, in another exemplary embodiment of the present invention, this embodiment also provides a switch identification system, including:

[0057] The acquisition module is used to acquire the switching level signal of the target device before the controller goes into sleep mode. The switching level signal is used to characterize the switching state of the target device. The target device and the controller are located in the same vehicle.

[0058] The filtering module is used to perform the first anti-jitter processing on the switch level signal acquired by the level acquisition module;

[0059] A switch identification module is used to perform a first classification identification on the switch level signal after the first anti-shake processing is completed;

[0060] The switch state storage module is used to store the switch level signal after the first classification identification into a target storage area that is determined in advance or in real time.

[0061] The control module is used to control the controller to trigger corresponding functional logic based on the switch level signals stored in the target storage area after the controller wakes up from sleep.

[0062] Specifically, this embodiment optimizes the switch acquisition model by adding a switch state storage module, enabling the controller to accurately identify switch state changes during sleep and wake-up. In the entire switch acquisition model, the acquisition module is responsible for acquiring external switch level signals and transmitting the acquired level states to the filtering module. The filtering module performs anti-bouncing processing on the switch levels using a filtering algorithm, and the anti-bouncing switch levels are then input to the switch identification module. The switch identification module performs a first-class identification of the filtered switch levels and transmits the identified switch states to the control module, which triggers the corresponding function according to the functional logic. Simultaneously, the switch identification module also transmits the identified switch states to the switch state storage module, which stores the switch states in the controller's non-volatile storage space. This storage will not be lost when the controller goes into sleep mode. Therefore, in this embodiment, the acquired switch states are stored before the controller goes into sleep mode, and the stored switch states are given to the filtering module after the controller is powered on and woken up, restoring the control logic to the state before sleep mode. Furthermore, to address the false state transitions caused by filtering time, this invention directly transmits the switch states from the switch state storage module to the filtering module, ensuring that the input state before filtering is the true final switch state before the controller goes into sleep mode.

[0063] In summary, this invention provides a switch state recognition system. First, it acquires the switch level signal of the target device before the controller goes into sleep mode. Then, it performs a first anti-jitter processing on the switch level signal and a first classification recognition on the anti-jitter processed switch level signal. Next, it stores the first-classified switch level signal in a pre-determined or real-time determined target storage area. After the controller wakes up from sleep mode, it identifies the switch state of the target device based on the switch level signal stored in the target storage area. The switch level signal characterizes the switch state of the target device, and the target device and controller are located in the same vehicle. Therefore, by storing the switch level signal, this system allows the controller to accurately identify the switch state of vehicle devices based on the stored switch level signal during sleep / wake-up states, and to implement corresponding control logic functions according to the switch level signal. This solves the problem of current controllers misidentifying switch state transitions and thus erroneously triggering functions when acquiring different switch level signals during sleep / wake-up states. Furthermore, after the controller wakes up, this system also eliminates the problem of misidentifying transitions by delaying the function control for a period of time, i.e., waiting for filtering to complete before performing function control. Furthermore, the system controller can recognize user on / off requests even during sleep mode, enhancing the intelligence of the control logic and improving functional control efficiency. Simultaneously, it prevents erroneous functional triggering during the sleep-wake process, thus forming a more effective and accurate functional closed loop.

[0068] Figure 5 A schematic diagram of an exemplary system architecture that can apply the technical solutions of one or more embodiments of the present invention is shown. Figure 5 As shown, the system architecture 100 may include terminal device 110, network 120, and server 130. Terminal device 110 may include various electronic devices such as smartphones, tablets, laptops, and desktop computers.

The switching level signal is used to characterize the switching state of the target device, and the target device and the controller are located in the same vehicle.

Figure 2 and / or Figure 3 The aforementioned switch state recognition method. Figure 6 A schematic diagram of a switch state recognition device 1000 is shown. (See also...) Figure 6 As shown, the switch status recognition device 1000 includes: a controller 1010, a memory 1020, a power supply 1030, a display unit 1040, and an input unit 1060.

It connects various components via various interfaces and lines, and executes various functions of the switch state identification device 1000 by running or executing software programs and / or data stored in the memory 1020, thereby performing overall monitoring of the switch state identification device 1000. In this embodiment of the invention, when the controller 1010 calls the computer program stored in the memory 1020, it executes, for example...
