[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of the present application.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0050] In a new energy vehicle, a shunt is often arranged in series in a to-be-measured circuit to detect the current flowing through the to-be-measured circuit and output the detection result. However, in actual situations, the devices in the shunt may fail to cause inaccurate measurement, and such problems are often found only when the user's vehicle is maintained regularly, which may cause many safety hazards.

[0051] To this end, the application provides a shunt control method, and it can be understood that a memory for storing the method and a processor for executing the method are arranged in the shunt, and the memory and the processor can be integrated in the same control device. The control device can be implemented by a main controller, such as an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a PLC, a SOC (System On Chip), and the like.

[0052] Reference Figure 1 In an embodiment of the application, the method comprises:

[0053] In step S100, working condition information of the shunt is acquired.

[0054] In this embodiment, optionally, the working condition information of the shunt can be information that can be detected by the shunt, such as a current value flowing through the shunt, a temperature value detected by a temperature detection module on the shunt, an air pressure value detected by an air pressure sensor on the shunt, and the like. Optionally, the working condition information of the shunt can also be program execution information in a circuit module thereon, for example, an error number, a reset number, a software runaway number, and the like in program execution of a control device therein.

[0055] In step S200, whether the shunt is in an abnormal state is confirmed according to the working condition information.

[0056] In step S300, when the shunt is in the abnormal state, a current abnormal module is determined, and the abnormal module is corrected.

[0057] In this embodiment, the control device can analyze whether the current shunt is in an abnormal state according to the acquired working condition information, for example, when a number of times that a current flowing through the shunt exceeds a preset current threshold (preset by a research and development personnel) reaches a preset number of times (preset by the research and development personnel), it is confirmed that the shunt is in an abnormal state. Alternatively, when the control device finds that a number of times of errors or a number of times of resets of itself in a time reaches a certain number of times, it is determined that the control device is in an abnormal state.

[0058] When the control device finds that the shunt is in an abnormal state, the circuit module provided on the shunt causing the abnormality is determined according to the abnormal state, and the circuit module is determined as an abnormal module. After the abnormal module is determined, the control device can first determine whether it can be self-corrected at present. If it cannot be self-corrected, the control device in the vehicle controller or the battery management module in communication connection with it sends a corresponding state prompt information, so that the vehicle pushes the information to the user, so that the user is clear about the risk of the shunt of the vehicle, so as to timely repair and maintain. In addition, if it can be self-corrected, the shunt can be self-corrected, for example, networking, adjusting the parameters of the corresponding abnormal module according to the same working condition information in the same working environment to re-correct the abnormal module. In this way, in the process of actual shunt in the use of the automobile, the shunt can self-check whether it is in an abnormal state, and correct in time when it is confirmed to be in an abnormal state, so as to ensure the accuracy and reliability of the shunt self-detection, and further ensure the safety of the automobile using the shunt.

[0059] The shunt control method includes: obtaining working condition information of the shunt; determining whether the shunt is in an abnormal state according to the working condition information; determining the current abnormal module when the shunt is in an abnormal state, and correcting the abnormal module. In this way, in the process of actual shunt in the use of the automobile, the shunt can self-check whether it is in an abnormal state, and correct in time when it is confirmed to be in an abnormal state, so as to ensure the accuracy and reliability of the shunt self-detection, and further ensure the safety of the automobile using the shunt.

[0060] Optionally, in an embodiment of the present application, the working condition information includes error reporting times and reset times. Figure 5

[0061] The step of determining whether the shunt is in an abnormal state according to the working condition information is specifically:

[0062] Step S220, when the error reporting times reach a second preset number within a preset second time length; or when the reset times reach a third preset number within a preset third time length, it is determined that the shunt is in an abnormal state.

[0063] The step of determining the current abnormal module when the shunt is in an abnormal state and correcting the abnormal module is specifically:

[0064] Step S370, determining the control device of the shunt as an abnormal module, and prompting the user to maintain the vehicle for correction.

[0065] ​In the embodiment, the second preset time length, the second preset number of times, the third preset time length and the third preset number of times can be set by the R&D personnel in advance. The control device can acquire the number of times of error occurrence in the process of executing the software and the number of times of resetting in the process of software runaway. If the number of times of error occurrence is too large or the number of times of resetting is too large within a certain time, the control device determines that the current shunt is in the software execution abnormal state and has a software execution risk. Then, the control device determines that it is an abnormal module and communicates with the vehicle controller to inform the vehicle controller that it has a software execution risk and requires the vehicle controller to prompt the user to maintain the vehicle for a certain time to correct and process the shunt to eliminate the risk. In this way, through the above settings, the control device can timely determine whether it has a software execution risk, and when the risk exists, timely prompt the user to maintain the vehicle to eliminate the possible future software failure in advance, thereby ensuring the reliability of the shunt and improving the safety of the vehicle.

[0066] Optionally, in an embodiment, the working condition information includes current information of the current flowing through the shunt.

[0067] According to the working condition information, the step of determining whether the shunt is in the abnormal state is specifically:

[0068] According to the current information, when the number of times that the current flowing through the shunt exceeds the preset current threshold value reaches the preset number of times, it is determined that the shunt is in the abnormal state.

[0069] In the embodiment, the shunt itself can be used to detect the current value flowing through itself, that is, the current value on the to-be-measured loop of the shunt. The shunt body connected in series to the to-be-measured loop is arranged in the shunt, and the shunt body includes an alloy resistor. The control device can calculate the current flowing through the shunt body, that is, the current flowing through the shunt and the current in the to-be-measured loop, by the voltage across the alloy resistor detected by the sampling module in the shunt. After the control device acquires the current flowing through the shunt, that is, the current flowing through the to-be-measured loop, it compares the current value of the current with the preset current threshold value pre-stored by the R&D personnel. If the number of times of exceeding the preset current threshold value is large, the control device can determine that the current shunt detects the current abnormality.

[0070] It can be understood that in the automobile, the shunt is often arranged in the output / input circuit of the power battery for detecting the current value of the power battery output / input. If the user steps on the accelerator (throttle) sharply to make the automobile accelerate quickly, the current may occasionally exceed the preset current threshold, not because of detection abnormality. Therefore, in the embodiment, when the number of times that the current flowing through the shunt exceeds the preset current threshold reaches the preset number of times, the step of determining the abnormal state of the shunt as the current detection abnormality state is specifically: when the number of times that the current flowing through the shunt exceeds the preset current threshold reaches the preset number of times within the preset first time length, it is determined that the shunt is in an abnormal state. The preset first time length can be obtained by the researchers through multiple experiments, for example, 1 Min. In this way, the detection accuracy of the control device for determining whether it is in the current detection abnormality state can be effectively improved.

[0071] It should be understood that in actual application, if the user steps on the accelerator multiple times in a short time, the current flowing through the shunt may also exceed the preset current threshold multiple times in a short time, which is easy to cause misjudgment.

[0072] For this purpose, with reference to Figure 2 In an embodiment of the present application, the method further comprises:

[0073] Step S400, acquiring the driving state of the automobile;

[0074] In the embodiment, the control device can also be in communication connection with the vehicle controller of the automobile to acquire the current driving state from the vehicle controller, for example, the current is an acceleration, constant speed, deceleration state, etc.

[0075] According to the working condition information, the step of determining whether the shunt is in an abnormal state is specifically:

[0076] Step S210, according to the current information, when the number of times that the current flowing through the shunt exceeds the preset current threshold reaches the preset number of times and the current when the current exceeds the preset current threshold does not match the driving state, it is determined that the shunt is in an abnormal state.

[0077] The current and the driving state do not match specifically: when the current flowing through the shunt exceeds the preset current threshold, the driving state of the automobile is not in the acceleration state.

[0078] In the embodiment, when the control device finds that the current flowing through the shunt exceeds the preset current threshold, the time when the current exceeds the preset current threshold is recorded, and the driving state of the vehicle obtained at the same time is called. If the current driving state is not an acceleration state or a deceleration state, it can be determined that the current exceeding the preset current threshold is abnormal current. For example, if the current vehicle driving state is a constant speed driving state, but the current exceeds the preset current threshold, the control device determines that the current exceeding the preset current threshold is abnormal current. Similarly, if the current exceeds the preset current threshold at the same time, the driving state of the vehicle is an acceleration state or a deceleration state, and the control device will not determine it as abnormal current. When the number of times of the above abnormal current reaches the preset number of times, the control device will confirm that the current shunt is in an abnormal state. Through the above setting, the accuracy of determining whether the shunt is in an abnormal current state is further improved.

[0079] In the present application, the shunt is provided with a shunt body for series connection to the circuit to be tested, which includes an alloy resistor and copper bars welded on both sides of the alloy resistor. The shunt also includes a circuit board for placing a circuit module, and the circuit is arranged on the shunt body. The circuit module arranged on the circuit board includes the above-mentioned control device, a sampling module for sampling the voltage across the alloy resistor, such as an analog-to-digital conversion module, and a second temperature detection module for detecting the temperature of the alloy resistor. At the same time, in order to improve the detection accuracy, such as to improve the temperature detection accuracy and eliminate the influence of thermoelectric potential, a first temperature detection module is often arranged on the copper bar. The first temperature detected by the first temperature detection module is often higher than the second temperature detected by the second temperature detection module, and the temperature difference between the two should be less than or equal to a preset temperature difference.

[0080] It should be understood that in actual application, the abnormal current is often caused by two aspects, one is that the sampling module itself has an abnormal sampling, and the other is that the second temperature detection module for detecting the temperature of the alloy resistor is abnormal, resulting in that the second temperature is too low, so that the control device calculates the current flowing through the shunt, and the result is too high (because the temperature rises, the resistance value of the alloy resistor also rises).

[0081] Therefore, with reference to Figure 3 In an embodiment of the present application, when the shunt is in an abnormal state, the step of determining the current abnormal module is specifically:

[0082] Step S310, acquiring the first temperature output by the first temperature sensor and the second temperature output by the second temperature sensor;

[0083] Step S320, when the current flowing through the shunt exceeds the preset current threshold, if the difference between the first temperature and the second temperature is greater than the preset temperature difference, it is determined that the current second temperature detection module is an abnormal module;

[0084] Step S330, when the current flowing through the shunt exceeds the preset current threshold, if the difference between the first temperature and the second temperature is less than or equal to the preset temperature difference, it is determined that the current sampling module is an abnormal module.

[0085] In the embodiment, when the control device determines that the current shunt current detection is abnormal, the difference between the first temperature and the second temperature is compared when the current is abnormal, i.e. when the current flowing through the shunt exceeds the preset current threshold. If the current difference is greater than the preset temperature difference, it can be determined that the current first temperature detection module is abnormal, resulting in that the temperature detection of the alloy resistor is too low. If the current difference is less than or equal to the preset temperature difference, it can be determined that the current second temperature detection is normal, and the current sampling module is an abnormal module.

[0086] Further, after determining that the current second temperature detection module is an abnormal module, the step of correcting the abnormal module is specifically:

[0087] Adjusting the parameters of the second temperature detection module to make the difference between the first temperature and the second temperature less than or equal to the preset temperature difference.

[0088] In the embodiment, when the control device determines that the second temperature detection module is abnormal, it communicates with the second temperature detection module to adjust the current temperature detection parameters, such as adjusting the parameters of the transfer function for calculating the second temperature, etc., so that the difference between the second temperature output by the second temperature detection module and the first temperature is less than or equal to the preset temperature difference. Alternatively, the control device can also compensate the obtained second temperature itself to make the difference between the first temperature and the second temperature less than or equal to the preset temperature difference, and determine the resistance value of the alloy resistor according to the second temperature after compensation, and then calculate the current value to eliminate the abnormality of current detection.

[0089] In addition, in another embodiment, with reference to Figure 4 , after determining that the current sampling module is an abnormal module, the step of correcting the abnormal module is specifically:

[0090] Step S340, obtaining the battery voltage of the battery and the driving state of the vehicle;

[0091] Step S350, obtaining the target current stored in the cloud server according to the battery voltage and the driving state of the vehicle;

[0092] Step S360, adjust the parameters of the sampling module according to the target current, so that the difference between the current flowing through the shunt and the target current is less than the preset current difference.

[0093] In the embodiment, the control device can communicate with the vehicle controller of the automobile or the BMS in the battery module where it is located to obtain the current voltage value of the battery, and obtain the driving state of the automobile according to the process of the above embodiment.

[0094] It can be understood that the shunt can also be provided with a wireless communication module, such as a 4G / 5G communication module, a WIFI communication module, etc. The control device can establish wireless communication with the cloud server of the manufacturer through the wireless communication module, and during the current working process, every time a preset period is passed, the current obtained current value flowing through the shunt, i.e. the current value of the battery input / output, the current voltage of the battery, and the driving state of the automobile can be uploaded to the cloud server and stored. When the control device confirms that the current sampling module is abnormal, the current battery voltage close to the cloud (for example, the difference between the battery voltage and the cloud battery voltage is less than the preset battery voltage difference), and the current under the same driving state are obtained from the cloud, and are used as the target current. At the same time, the parameters of the current sampling module, such as the transfer function in it, are adjusted accordingly, until the difference between the current value calculated by the control device according to the result obtained by the sampling module and the target current is less than the preset current difference, for example, less than 1A.

[0095] In this way, through the above setting, the application can identify the abnormal module that currently has a problem and correct it when confirming that the current shunt current detection is abnormal, so as to relatively improve the accuracy of the current shunt detection, and further ensure the reliability of the shunt use.

[0096] It can be understood that after the shunt is corrected, the user can still be prompted by the vehicle controller to maintain the shunt of the automobile in a timely manner as in the above embodiment.

[0097] In addition, it can be understood that in combination with the content of the above embodiment, the control device can also evaluate the risk level of the abnormal state of the shunt and give corresponding prompts to meet the needs of the user. Specifically, the control device will record the current detection result or the current detection result in a certain period of time when an error occurs or is reset each time. When the control device determines that it is an abnormal module with risk according to the process of the above embodiment, the current detection result recorded in the period when the error occurs or is reset, or the error frequency is increased is called out, and whether the above current detection result is abnormal is determined according to the above embodiment.

[0098] If the current detection result is abnormal and the source of the abnormality of the current detection result is the first / second temperature detection module or the sampling module, or the current detection result is normal, the control device determines that the current self is in an abnormal state, but temporarily does not greatly affect the accuracy of current detection, and outputs a corresponding risk gear signal to the vehicle controller, so that the vehicle controller gives a corresponding prompt. For example, the vehicle controller prompts the user that "the current vehicle state has a certain risk, and regular maintenance is recommended".

[0099] If the current detection result is abnormal and the first / second temperature detection module and the sampling module are normal, for example, after adjusting the target parameters of the sampling module, the current detection is still abnormal in the subsequent current detection process, it can be determined that the original sampling module is not abnormal, but the data processing of the control device is abnormal. At this time, the control device directly outputs the current saved in the cloud at the close battery voltage (for example, the difference between the battery voltage and the cloud battery voltage is less than the preset battery voltage difference) and the same driving state as the actual current detection result, and outputs a corresponding risk gear signal to the vehicle controller, so that the vehicle controller gives a corresponding prompt. For example, the vehicle controller prompts the user that "the current vehicle state has a great risk, and immediate repair is recommended". In this way, in actual application, the shunt can also realize the judgment of the risk gear of the current vehicle and give the corresponding prompt to the user, so as to improve the convenience of use of the user.
