[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Dark current, also known as static current, leakage current or parasitic current, refers to the discharge current of the battery after the ignition switch and electrical switch of the car are disconnected, generally in "mA". For automotive electronic systems, the existence of dark current can maintain the data memory function of the control unit, or provide power for the car anti-theft system for all-weather monitoring. Although the existence of dark current can ensure the continuation of certain functions of the car, excessive dark current of the whole vehicle will cause difficulties in starting the car or failure of the anti-theft system. Therefore, it is usually necessary to adjust the dark current to ensure that the dark current is minimized.

[0024] There are two main aspects to dark current processing. The first aspect is to configure the controller pins to minimize the power consumption of the controller periphery. The other aspect is to set the controller to enter low power mode. Each controller model is different, and the corresponding configuration of entering low power mode is also different.

[0025] Based on this, the present application mainly proposes a dark current processing method for a controller (such as MCU or SOC, etc.) for the above-mentioned pin configuration, processing configuration, electronic equipment and storage medium to achieve dark current adjustment.

[0026] Specifically, a dark current processing method, a processing device, an electronic device, and a storage medium according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0027] Figure 1 is a flow chart of a dark current processing method according to an exemplary embodiment. Figure 1 As shown, the dark current processing method includes:

[0028] Step S110, obtaining pin information of the controller, and dividing the pins of the controller into multiple pin combinations based on the pin information, wherein the multiple pin combinations include a first pin combination, a second pin combination, and a third pin combination, wherein the first pin combination includes pins associated with external power control, the second pin combination includes pins associated with communication and / or wake-up, and the third pin combination includes other pins except the first pin combination and the second pin combination.

[0029] For example, the present invention can obtain the pin information of the controller according to the model of the controller, and divide it into different pin combinations based on the function of the pin of the controller and the correlation with the dark current. For example, taking MCU as an example, the function of the pin of MCU varies with different models and manufacturers, and the pins included are commonly power pins, input and output pins (I / O pins), clock pins, external interrupt pins, timer / counter pins, and debug structure pins. Therefore, the present invention can divide the power pins for controlling the external power supply into the first pin combination, the serial port output pins for communicating with the outside and the wake-up pins for wake-up into the second pin combination, and then divide the remaining pins into the third pin combination. The purpose of dividing the pin combination is to facilitate the subsequent reasonable and orderly configuration of the pin status based on different configuration strategies.

[0030] Step S120, combining current detection to test the first pin combination, the third pin combination and the second pin combination in sequence, determine the state to be set of the pins of the controller when the controller is in sleep mode, and generate corresponding setting information, wherein the pins in the first pin combination are set to a state capable of turning off the external power supply, the pins in the third pin combination are set to a state that meets preset current conditions, and the pins in the second pin combination are set to a state related to their functions or related to the application of the controller.

[0031] For example, after the pins of the controller are divided into different combinations, the present invention combines current detection to determine the states to be set for the pins according to the different combinations. The states to be set for the pins generally include high impedance state, input state, output high level, and output low level.

[0032] Figure 2 The present invention is a schematic diagram of dark current processing hardware connection. The present invention introduces a current detection module, which is preferably inserted into a controller circuit board in the form of a plug-in, so as to facilitate the detection of current size during the pin state setting process and ensure that the current in the set pin state meets the dark current requirements.

[0033] Among them, for the pins of the first pin combination, since they are connected to the external power supply, if the dark current is to be reduced so that the dark current size meets the requirements, it is necessary to set the state of the pins of the first pin combination so that the controllable power supply can be turned off to reduce the current generated by the external power supply.

[0034] For the third pin combination, the present invention introduces a current measurement module, and determines the state of the pin that meets the current condition by setting the state of the pin differently and using the current measurement module to measure the current of the controller circuit accordingly.

[0035] For the second pin combination, since most of the pins in the second pin combination are functional pins, such as the special pins such as the communication and wake-up functions mentioned above, it is necessary to determine the state to be configured based on the functions of the corresponding pins in the pin combination and the application scenario of the current controller.

[0036] Step S130, setting the pins of the controller according to the setting information, and setting the controller to a low power consumption mode to reduce the dark current consumed by the controller when it is in sleep mode.

[0037] For example, when it is obtained that the entire vehicle needs to enter sleep mode, the pins of the controller are set in sequence according to the setting information obtained in the above steps, and after the setting is completed, the controller is configured to a low power consumption mode to complete the dark current adjustment of the controller.

[0038] It can be seen from the embodiments of the present invention that, on the one hand, the present invention realizes automatic adjustment of dark current by dividing the pins of the controller into different pin combinations, and then setting the states of the pins for different pin combinations. Compared with the prior art, there is no need for excessive manual adjustments, which improves development efficiency and reduces the development cycle. On the other hand, there is no need to pretend any hardware or change the hardware on the controller circuit board itself, so as to realize batch adjustment of the controller circuit. On the other hand, the present invention pre-adjusts the pin state before the controller enters the low power consumption mode to better meet the dark current requirements.

[0039] The above steps are further described and explained in detail below with reference to the accompanying drawings and examples.

[0040] In a preferred embodiment, the dark current processing method further includes: before testing the pins of the controller, obtaining a monitoring log for the controller, and determining whether it is necessary to test the pins of the controller based on the monitoring log.

[0041] For example, it has been mentioned above that the present invention introduces a current measurement circuit, so when the current measurement module is inserted into the controller circuit, the present invention can detect the high-level input caused by the insertion of the current measurement module. Further, in response to the high-level input signal, the present invention obtains a saved monitoring log from a memory (e.g., RAM, etc.), and the monitoring log can store historical information on the dark circuit processing of the controller. Therefore, it can be determined whether the dark current adjustment has been performed on the controller through the monitoring log. If there is no record in the monitoring log, it means that the controller has not performed the dark current adjustment, then the subsequent dark current processing can be triggered to configure the state of the pin. If there is a corresponding record in the monitoring log, it means that the controller has performed the dark current adjustment, then it is not necessary to perform the dark current adjustment on the controller. In this way, repeated adjustments to the controller circuit can be avoided in this way, especially for batch adjustments, and the processing efficiency of the dark current can be effectively improved.

[0042] In a preferred implementation, testing the first pin combination includes: setting the state of each pin of the first pin combination to an output low level state and detecting a current value in the output low level state.

[0043] In this way, by configuring the state of each pin of the first pin combination to output a low level, the external controllable power supply can be effectively turned off to reduce the dark current caused by the external power supply. During the setting process, current detection can not only ensure the accuracy of the pin state setting but also ensure that the dark current meets the requirements.

[0044] In a preferred implementation, testing the third pin combination includes:

[0045] Setting the states of all pins in the third pin combination to a high impedance state, and detecting a current current value;

[0046] Sequentially set the state of each pin in the third pin combination to an input state, an output high level, and an output low level, and detect the current value in the corresponding state;

[0047] Based on the current value of each pin in different states, the state corresponding to the minimum current value is used as the final state to be configured for the pin.

[0048] For example, suppose that the third pin combination includes 10 pins. First, the states of the 10 pins are configured to be high impedance state. After stabilization for 5 seconds, the current value in the current high impedance state is detected and saved. Secondly, one of the 10 pins is set to input state, output high level and output low level respectively. After stabilization for 5 seconds, the current values ​​in these three states are detected accordingly. Then, the four current values ​​detected, namely, high impedance state, input state, output high level and output low level, are compared in size. For example, if it is determined that the current value under the output high level is the smallest, it is determined that the output high level is the final state to be configured for the pin. Similarly, the remaining 9 pins are configured in sequence according to the above method, so as to obtain the state corresponding to the minimum current value of the corresponding pin. Then, the configuration information of the 10 pins, that is, the pin information and the corresponding state to be configured, is saved in a memory (such as DATA FLASH).

[0049] In a preferred embodiment, the testing of the second pin combination includes: setting the state of the pin with wake-up function to the wake-up function state, and setting the state of other pins of the second pin combination to a high impedance state and detecting the current value under the current state setting.

[0050] For example, since this application is aimed at processing dark current when the controller is in sleep mode, the wake-up pin needs to be configured as a wake-up function. At the same time, since other pins have corresponding special functions, such as serial port communication, in order to avoid mutual influence and cause excessive dark current, other pins are set to a high-impedance state to effectively isolate the corresponding pins from other external factors.

[0051] In a preferred embodiment, after setting the state of the pin of the controller, the dark current processing method also includes: adjusting the state of the pin of the second pin combination according to the operation of the controller, and detecting the current value so that the adjusted current value meets the dark current requirement.

[0052] For example, since the pin state adjustment mentioned above is based on the overall adjustment after the pins are grouped to meet the minimization of dark current, the overall operation of the controller circuit is ignored, which may cause problems in the functional coordination between the pins after adjustment. After the pin state setting is completed, the present invention can monitor the functional operation of the controller. If there is a problem with the operation, the present invention can analyze the problem and manually adjust the state of the associated pins. In this way, through manual fine-tuning, the associated pins are adjusted to other appropriate states, and combined with current detection, it is ensured that the adjusted current meets the current requirements.

[0053] The embodiment of the present invention can monitor after the pin status is set, and then manually fine-tune according to the individual status that occurs, thereby improving the reliability and accuracy of dark current processing.

[0054] Figure 3 A dark current processing process of the present invention is shown, such as Figure 3 As shown, the specific process is as follows:

[0055] Step S301, setting the pin state of the first pin combination, thereby turning off all controllable power supplies, detecting the current value of the pin state outputting a low level state and saving it.

[0056] Step S302, set the pins of the third pin combination to high impedance state, and determine the state to be set for each pin of the third pin combination in combination with current detection. Then, first set the state of all pins of the third pin combination to high impedance state, and after stabilization for 5 seconds, detect the current value. Then, take out the pins one by one to perform state switching setting.

[0057] Step S303, setting the pin to output a high level state, and using a current detection module to detect the current size.

[0058] Step S304, compare the current size of the pin in the previous state (high impedance state), if the current in the current high level output state is smaller than the current in the high impedance state, jump to step S305, otherwise jump to step S306.

[0059] Step S305, recording the current current value and the pin state corresponding to the current value as an output high level state.

[0060] Step S306, the state of the pin is then output as a low level state to detect the current size.

[0061] Step S307, compare the current magnitude currently detected with the recorded current magnitude. It should be noted here that if it is jumped over via step S304 and step S306, then the current magnitude recorded at this time should be the current value of the output high level state. If it is jumped over via step S305 and step S306, then the current magnitude recorded at this time should be the current value of the high impedance state. Similarly, if the current value currently detected is less than the recorded current value, then jump to step S308, otherwise jump to step S309.

[0062] Step S308, recording the current value currently detected and the pin state corresponding to the current value as an output low level state.

[0063] Step S309, setting the state of the pin to an input state, and detecting the current magnitude.

[0064] Step S310, compare the current value currently detected with the recorded current value, if the current value currently detected is smaller than the recorded current value, then jump to step S311, otherwise jump to step S312.

[0065] Step S311, recording the current value currently detected and the pin state corresponding to the current value as an input state.

[0066] Step S312, saving the state of the pin with the smallest final current value.

[0067] Step S313, determining whether it is the last pin of the third pin combination, if not, jump to step S314.

[0068] Step S314, taking out the next pin from the third pin combination, jumping to step S303, and performing state switching setting for the next pin taken out.

[0069] The above steps are looped until step S314 determines that the pin is the last pin, thereby completing the pin state setting, and saving and obtaining the states to be configured of all pins of the third pin combination.

[0070] Then when the controller needs to sleep, each pin is set to the desired configuration state based on the obtained configuration information, and then the controller is switched to the low power mode, and finally the dark current processing is completed.

[0071] In summary, the method provided by the present invention has the following advantages:

[0072] 1) The present invention can divide the pins into different groups based on the pin information of the controller, perform pin tests according to the different groups, and realize automatic adjustment of the controller pins;

[0073] 2) The pin status is adjusted in combination with the current detection module. There is no need to add any hardware to the controller circuit board or make hardware adjustments to the circuit board. Other configuration processes are implemented by software, which can achieve batch adjustment of multiple controllers.

[0074] 3) Reduces the manual configuration process, improves engineers' development efficiency, and shortens the development cycle.
