[0028] The present disclosure will be further described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0029] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0030] like Figure 1 As shown, the embodiment of the present disclosure provides a method for determining the power state of a vehicle-mounted controller, comprising:

[0031] Step S101: using a plurality of filtering algorithms to obtain a plurality of first voltages of the vehicle controller at the same time, wherein the plurality of filtering algorithms correspond to the plurality of first voltages one by one, and the plurality of filtering algorithms have different characteristics.

[0032] Step S102: acquiring first voltage weight information according to the current operation stage of the vehicle controller and the preset voltage interval in which the plurality of first voltages are located, wherein the first voltage weight information includes first weights corresponding to the plurality of filtering algorithms respectively.

[0033] Step S103: Obtain the second voltage of the vehicle controller using a weighted average algorithm according to the first weights and the first voltages corresponding to the plurality of filtering algorithms.

[0034] Step S104: Determine the power state of the vehicle controller according to the second voltage.

[0035] According to the embodiments of the present disclosure, it should be noted that:

[0036] The multiple filtering algorithms may be understood to include at least two filtering algorithms. The filtering algorithm may be any filtering algorithm in the prior art, and is not specifically limited here.

[0037] The multiple filtering algorithms correspond to the multiple first voltages one by one, and it can be understood that at a certain moment, the first voltage of the vehicle controller is obtained using each filtering algorithm.

[0038] A variety of filtering algorithms have different characteristics. It can be understood that one of the filtering algorithms has the characteristics of high sensitivity, one of the filtering algorithms has the characteristics of strong anti-interference, and one of the filtering algorithms has the characteristics of high computational efficiency. It can also be understood that one of the filtering algorithms has the characteristics of high sensitivity and strong anti-interference, and one of the filtering algorithms has the characteristics of high computational efficiency. It can also be understood that one of the filtering algorithms has the characteristics of high sensitivity and high computational efficiency, and one of the filtering algorithms has the characteristics of strong anti-interference. It can also be understood that one of the filtering algorithms has the characteristics of strong anti-interference and high computational efficiency, and one of the filtering algorithms has the characteristics of high sensitivity. The above is only used as an example to illustrate that a variety of filtering algorithms can have one or more different characteristics. A variety of filtering algorithms include but are not limited to Kalman filtering algorithm, Wiener filtering algorithm, Gaussian filtering algorithm, median filtering algorithm, mean filtering algorithm, etc. Among them, the Kalman filter algorithm has high sensitivity, high anti-interference ability, and low calculation efficiency; the Wiener filter algorithm has high sensitivity, medium anti-interference ability, and low calculation efficiency; the Gaussian filter algorithm has medium sensitivity, medium anti-interference ability, and medium calculation efficiency; the median filter algorithm has medium sensitivity, high anti-interference ability, and medium calculation efficiency; the mean filter algorithm has low sensitivity, medium anti-interference ability, and high calculation efficiency. When obtaining the first voltage of the vehicle controller, at least two required filter algorithms can be selected from the above multiple filter algorithms according to the requirements of the filter characteristics.

[0039] The preset voltage range can be set according to the function and model of the vehicle controller. The preset voltage range may include but is not limited to the standard operating voltage range of the vehicle controller, the voltage warning range, the undervoltage alarm range, the overvoltage alarm range, the voltage abnormality range, etc. When the voltage of the vehicle controller obtained is in different preset voltage ranges, different operation and protection strategies will be adopted for the vehicle controller. For example, when the voltage of the vehicle controller obtained is in the standard operating voltage range, all components on the vehicle controller can work normally. When the voltage of the vehicle controller obtained is in the voltage warning range, the undervoltage alarm range, and the overvoltage alarm range, some components on the vehicle controller can work normally, and certain protection strategies and measures need to be taken. When the voltage of the vehicle controller obtained is in the voltage abnormality range, the vehicle controller cannot operate normally or the operation will damage specific components on it. At this time, emergency protection strategies and measures need to be taken. For example, such as Figure 2As shown, there is now a vehicle controller equipped with FPGA (Field Programmable Gate Array), screen driver chip and other components that are sensitive to power supply voltage. The preset voltage range of the vehicle controller is 8V to 15V for standard working voltage, 6V to 8V and 15 to 17V for voltage warning, 5V to 6V for undervoltage alarm, 17 to 20V for overvoltage alarm, and the rest of the voltage values ​​are voltage abnormal ranges.

[0040] The current operation phase of the vehicle controller includes an initialization phase (power-on) and a steady operation phase, wherein the steady operation phase occurs after the initialization phase in terms of time. Figure 2 As shown, 0-500ms (milliseconds) is the initialization stage of the vehicle controller, and after 500ms is the stable operation stage of the vehicle controller.

[0041] Each filtering algorithm has different weights in different preset voltage intervals, and each filtering algorithm has different weights in the same preset voltage interval in the initialization phase and the stable operation phase. Figure 2 As shown, in the initialization stage, the preset voltage interval A0 of the vehicle controller is the standard working voltage of 8V~15V, the voltage warning interval A1 is 6V~8V and 15~17V, the undervoltage alarm interval A2 is 5V~6V, the overvoltage alarm interval A2 is 17~20V, and the remaining voltage values ​​are the voltage abnormality interval A3. In the stable operation stage, the preset voltage interval B0 of the vehicle controller is the standard working voltage of 8V~15V, the voltage warning interval B1 is 6V~8V and 15~17V, the undervoltage alarm interval B2 is 5V~6V, the overvoltage alarm interval B2 is 17~20V, and the remaining voltage values ​​are the voltage abnormality interval B3. Figure 2 In each partitioned interval, Figure 3 As shown, different weights are configured for multiple filtering algorithms. Figure 3 A0 to A3 and B0 to B3 in the figure are configured with weights for the three filtering algorithms, where the weights of the first row in A0 to A3 and B0 to B3 correspond to the first filtering algorithm, the weights of the second row in A0 to A3 and B0 to B3 correspond to the second filtering algorithm, and the weights of the third row in A0 to A3 and B0 to B3 correspond to the third filtering algorithm.

[0042] The power status can be understood as whether the current power supply voltage of the vehicle controller will cause damage to some of the components mounted thereon or cause the vehicle controller to fail to operate.

[0043] According to the technology of the embodiment of the present disclosure, by using multiple filtering algorithms to simultaneously collect the first voltage of the vehicle controller, the advantages and characteristics of different filtering algorithms can be combined to obtain a more accurate working voltage value of the vehicle controller, solving the problem that a single filtering algorithm has poor sensitivity and cannot track the actual voltage change in real time, and the problem that it is difficult to filter out noise interference due to poor anti-interference, so that the voltage of the vehicle controller adopts sampling requirements that take into account both anti-disturbance and real-time performance. The second voltage obtained by fusion sampling of multiple filtering algorithms can more accurately characterize the actual voltage value of the vehicle controller, so that the second voltage can be used to accurately monitor the power status of the vehicle controller.

[0044] In one implementation, the method for determining the power state of the vehicle controller provided in the embodiment of the present disclosure includes steps S101 to S104, wherein step S101: using multiple filtering algorithms to obtain multiple first voltages of the vehicle controller at the same time, including:

[0045] At least a first filtering algorithm with high sensitivity, a second filtering algorithm with strong anti-interference characteristics, and a third filtering algorithm with high computational efficiency are used to obtain multiple first voltages of the vehicle controller at the same time.

[0046] According to the embodiments of the present disclosure, it should be noted that:

[0047] Sensitivity can be understood as the degree to which the filter responds to small changes in the input signal.

[0048] Anti-interference can be understood as the ability of the filter to resist noise and interference.

[0049] Computational efficiency can be understood as the computational complexity of the filter algorithm.

[0050] According to the technology of the embodiment of the present disclosure, by using multiple filtering algorithms to simultaneously collect the first voltage of the vehicle controller, the advantages and characteristics of different filtering algorithms can be combined to obtain a more accurate working voltage value of the vehicle controller, solving the problem that a single filtering algorithm has poor sensitivity and cannot track the actual voltage change in real time, and the problem that it is difficult to filter out noise interference due to poor anti-interference, so that the voltage of the vehicle controller adopts sampling requirements that take into account both anti-disturbance and real-time performance. The second voltage obtained by fusion sampling of multiple filtering algorithms can more accurately characterize the actual voltage value of the vehicle controller, so that the second voltage can be used to accurately monitor the power status of the vehicle controller.

[0051] In one embodiment, the method for determining the power state of the vehicle controller provided by the embodiment of the present disclosure includes steps S101 to S104, wherein step S102: obtaining first voltage weight information according to the current operation stage of the vehicle controller and the preset voltage interval in which the plurality of first voltages are located, includes:

[0052] According to the current operation stage of the vehicle-mounted controller, second voltage weight information corresponding to the operation stage is determined.

[0053] When a plurality of first voltages are located in the same preset voltage interval, first voltage weight information corresponding to the same preset voltage interval is obtained from the second voltage weight information.

[0054] According to the embodiments of the present disclosure, it should be noted that:

[0055] The current operation phase of the on-board controller includes an initialization phase (power-on) and a steady operation phase, wherein the steady operation phase occurs after the initialization phase in terms of time.

[0056] like Figure 2 , Figure 3 As shown, if the current operating stage of the vehicle controller is a stable operating stage, and the voltage values ​​of the first voltage obtained by using multiple filtering algorithms are all in the preset voltage interval B0, then the second voltage can be obtained by using only the first voltage weight information corresponding to the B0 interval through a weighted average algorithm.

[0057] According to the technology of the embodiment of the present disclosure, by configuring different weights for multiple filtering algorithms according to different operating stages and different voltage ranges of the vehicle controller, the multiple filtering algorithms can be more adapted to the current voltage sampling scenario, so that the second voltage finally obtained using multiple filtering algorithms is more accurate.

[0058] In one embodiment, the method for determining the power state of the vehicle controller provided by the embodiment of the present disclosure includes steps S101 to S104, wherein step S102: obtaining first voltage weight information according to the current operation stage of the vehicle controller and the preset voltage interval in which the plurality of first voltages are located, includes:

[0059] According to the current operation stage of the vehicle-mounted controller, second voltage weight information corresponding to the operation stage is determined.

[0060] When the plurality of first voltages are located in different preset voltage intervals, first voltage weight information corresponding to the different preset voltage intervals is respectively acquired from the second voltage weight information.

[0061] According to the embodiments of the present disclosure, it should be noted that:

[0062] The current operation phase of the on-board controller includes an initialization phase (power-on) and a steady operation phase, wherein the steady operation phase occurs after the initialization phase in terms of time.

[0063] like Figure 2 , Figure 3As shown, if the current operating stage of the vehicle controller is a stable operating stage, and the voltage values ​​of the first voltage obtained by using multiple filtering algorithms are located in the preset voltage intervals B0 and B1, it is necessary to use the first voltage weight information corresponding to the B0 and B1 intervals to obtain the second voltage.

[0064] According to the technology of the embodiment of the present disclosure, by configuring different weights for multiple filtering algorithms according to different operating stages and different voltage ranges of the vehicle controller, the multiple filtering algorithms can be more adapted to the current voltage sampling scenario, so that the second voltage finally obtained using multiple filtering algorithms is more accurate.

[0065] In one implementation, the method for determining the power state of the vehicle controller provided by the embodiment of the present disclosure includes steps S101 to S104, wherein step S103: obtaining the second voltage of the vehicle controller by using a weighted average algorithm according to first weights and multiple first voltages respectively corresponding to multiple filtering algorithms, including:

[0066] The first voltage weight information corresponding to different preset voltage intervals is weighted and averaged to obtain the second voltage weight information, wherein the second voltage weight information includes second weights corresponding to the plurality of filtering algorithms respectively.

[0067] The second voltage of the vehicle controller is obtained by using a weighted average algorithm according to the second weights corresponding to the multiple filtering algorithms and the multiple first voltages.

[0068] According to the embodiments of the present disclosure, it should be noted that:

[0069] The first voltage weight information corresponding to different preset voltage intervals is weighted and averaged. It can be understood that if multiple first voltages obtained through multiple filtering algorithms are respectively located in different preset voltage intervals, it is necessary to weight-average the first voltage weight information of different preset voltage intervals to obtain new second voltage weight information that combines the weights of two preset voltage intervals.

[0070] According to the technology of the embodiment of the present disclosure, by configuring different weights for multiple filtering algorithms according to different operating stages and different voltage ranges of the vehicle controller, the multiple filtering algorithms can be more adapted to the current voltage sampling scenario, so that the second voltage finally obtained using multiple filtering algorithms is more accurate.

[0071] In one example, when the vehicle controller is in the initialization operation stage, because the various parts of the vehicle controller system are not yet stable, it is necessary to quickly check the initial external environment of the system and quickly capture abnormal voltages that may damage sensitive components. For this reason, the weight focuses on filtering algorithms with high sensitivity and poor noise resistance. From A0 to A3, if the power supply deteriorates and the abnormal voltage needs to be captured more and more sensitively, the weight of the filtering algorithm with higher sensitivity increases, while the weight of the filtering algorithm with strong anti-disturbance and delayed response decreases.

[0072] In one example, when the vehicle controller is in a stable operation stage, because the various parts of the vehicle controller system work smoothly, the probability of sudden changes in the power supply voltage or even damage to the device is relatively low. At this stage, the main purpose of voltage monitoring is to filter out various external noise interferences during operation, and at the same time, it can also capture abnormal changes in voltage. To this end, focus on filtering algorithms with strong anti-noise capabilities and high robustness. Reduce the weight of filtering algorithms with poor noise suppression capabilities. From B0 to B3, if the power supply is getting worse and worse, more and more sensitive capture of abnormal voltages is required, so the weight of filtering algorithms with higher sensitivity increases, while the weight of filtering algorithms with strong anti-disturbance and delayed response decreases.

[0073] In one implementation, the method for determining the power state of the vehicle controller provided in the embodiment of the present disclosure includes steps S101 to S104, wherein step S104: determining the power state of the vehicle controller according to the second voltage includes:

[0074] According to the pre-divided operating voltage interval of the on-board controller, a target sub-interval in which the second voltage is located is determined, wherein the operating voltage interval includes a plurality of sub-intervals.

[0075] According to the target sub-interval, the power state of the vehicle controller is determined.

[0076] According to the embodiments of the present disclosure, it should be noted that:

[0077] The multiple sub-intervals included in the working voltage interval can correspond to the preset voltage interval. For example, when the voltage of the vehicle controller obtained is in the standard working voltage interval, all devices on the vehicle controller can work normally, and it is determined that the power supply status is normal, and no protective measures are required. When the voltage of the vehicle controller obtained is in the voltage warning interval, the undervoltage alarm interval, and the overvoltage alarm interval, some devices on the vehicle controller can work normally, and it is determined that certain protection strategies and measures need to be taken for the vehicle controller under this power state. When the voltage of the vehicle controller obtained is in the abnormal voltage interval, the vehicle controller cannot operate normally or the operation will damage specific components on it. At this time, it is determined that emergency protection strategies and measures need to be taken for the vehicle controller under this power state.

[0078] According to the technology of the embodiment of the present disclosure, by determining the voltage range in which the second voltage is located, the power status of the vehicle controller can be accurately determined, so that corresponding protection strategies and protection measures for the vehicle controller can be adopted to prevent the devices mounted on the vehicle controller from being damaged when the operating voltage of the vehicle controller is abnormal.

[0079] like Figure 4 As shown, an embodiment of the present disclosure provides a device for determining a power state of a vehicle-mounted controller, comprising:

[0080] The first acquisition module 410 is used to acquire multiple first voltages of the vehicle controller at the same time by using multiple filtering algorithms, wherein the multiple filtering algorithms correspond to the multiple first voltages one by one, and the multiple filtering algorithms have different characteristics.

[0081] The second acquisition module 420 is used to acquire first voltage weight information according to the current operation stage of the vehicle controller and the preset voltage interval in which the multiple first voltages are located, wherein the first voltage weight information includes first weights corresponding to the multiple filtering algorithms respectively.

[0082] The calculation module 430 is used to obtain the second voltage of the vehicle controller by using a weighted average algorithm according to the first weights and the first voltages corresponding to the plurality of filtering algorithms.

[0083] The determination module 440 is used to determine the power state of the vehicle controller according to the second voltage.

[0084] In one implementation, the first acquisition module 410 is used to:

[0085] At least a first filtering algorithm with high sensitivity, a second filtering algorithm with strong anti-interference characteristics, and a third filtering algorithm with high computational efficiency are used to obtain multiple first voltages of the vehicle controller at the same time.

[0086] In one implementation, the second acquisition module 420 is used to:

[0087] According to the current operation stage of the vehicle-mounted controller, second voltage weight information corresponding to the operation stage is determined.

[0089] In one implementation, the second acquisition module 420 is used to:

[0090] According to the current operation stage of the vehicle-mounted controller, second voltage weight information corresponding to the operation stage is determined.

[0091] When the plurality of first voltages are located in different preset voltage intervals, first voltage weight information corresponding to the different preset voltage intervals is respectively acquired from the second voltage weight information.

[0092] In one embodiment, the calculation module 430 is used to:

[0093] The first voltage weight information corresponding to different preset voltage intervals is weighted and averaged to obtain the second voltage weight information, wherein the second voltage weight information includes second weights corresponding to the plurality of filtering algorithms respectively.

[0094] The second voltage of the vehicle controller is obtained by using a weighted average algorithm according to the second weights corresponding to the multiple filtering algorithms and the multiple first voltages.

[0095] In one implementation, the determination module 440 is configured to:
