DETAILED DESCRIPTION

[0018] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0019] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0020] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0021] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0022] In the fine-tuning of automotive electronic systems, the feedback current of the turn signal plays a key role. Comparing the feedback current with the calibration current can detect whether the circuit of the turn signal is in an open circuit state. In common vehicle designs, the calibration current of the turn signal is preset to a constant value, which remains constant throughout the life cycle of the vehicle, ensuring that the basic functions of the turn signal can be stably implemented. However, this calibration method has certain limitations. In certain specific situations, even if the bulb operates normally, the feedback current may deviate due to external factors (such as fluctuations in the power supply voltage). For example, when the system voltage becomes smaller, the feedback current will also become smaller accordingly, and when the system voltage becomes larger, the feedback current will also become larger accordingly. This situation may cause the system to misjudge it as an open circuit fault, especially when the turn signal is not on. It is often hidden to distinguish whether it is a short circuit, a break, or an input button failure, which makes accurate judgment complicated, thereby affecting the performance and reliability of the turn signal.

[0023] In response to the above problems, an embodiment of the present application provides a turn signal control method, which uses different calibrated current intervals to compare feedback current under different system voltages, and can accurately determine whether the vehicle turn signal is faulty, thereby improving the reliability of the turn signal.

[0024] Figure 1 The flowchart of a turn signal control method provided in an embodiment of the present application is shown in FIG. The method can be executed by a vehicle controller, such as Figure 1 As shown, the method may specifically include: Step 101 , in response to a turn-on operation of a vehicle turn signal, obtaining a current system voltage of the vehicle and a feedback current of the vehicle turn signal.

[0025] Step 102: determine a calibrated current interval associated with the system voltage.

[0026] Step 103 , when the feedback current exceeds the calibrated current range, the vehicle turn signal lamp is controlled to flash at a first frequency, wherein the first frequency is greater than the flashing frequency of the vehicle turn signal lamp when the vehicle turn signal lamp is working normally.

[0027] The system voltage can be regarded as the voltage applied by the vehicle battery to the vehicle turn signal. When the vehicle turn signal is working, the current flowing through the vehicle turn signal circuit is the feedback current. If the system voltage fluctuates due to some special reasons, even if the circuit of the vehicle turn signal is normal, the feedback current will also change accordingly. Therefore, when the vehicle controller turns on the vehicle turn signal, in addition to obtaining the feedback current, it also obtains the current system voltage of the vehicle.

[0028] In an embodiment of the present application, different system voltages correspond to different calibrated current intervals. After obtaining the current system voltage of the vehicle, the vehicle controller can search for the calibrated current interval associated with the system voltage. Specifically, the vehicle controller can obtain a pre-stored calibrated current mapping table, which contains multiple preset voltages, and each preset voltage has a mapping relationship with a preset current interval. Based on the mapping relationship between the preset voltage and the preset current interval, the vehicle controller can determine the calibrated current interval corresponding to the current system voltage. During actual execution, the vehicle controller can determine a target preset voltage that matches the current system voltage among multiple preset voltages based on a preset algorithm, and then determine the preset current interval corresponding to the target preset voltage as the calibrated current interval.

[0029] After determining the calibrated current interval, the vehicle controller compares the feedback current with the calibrated current interval. If the feedback current exceeds the calibrated current interval, it can be determined that the vehicle turn signal is faulty, and the vehicle turn signal is controlled to flash at a first frequency. If the feedback current is stable within the calibrated current interval, it can be determined that the vehicle turn signal is not faulty, and the vehicle turn signal is controlled to flash at a second frequency. The second frequency can be regarded as the flashing frequency when the vehicle turn signal is working normally, and the first frequency is greater than the second frequency. Optionally, the first frequency can be set to twice the second frequency.

[0030] When the feedback current is not within the expected range (calibrated current range), it can be regarded as a vehicle turn signal circuit fault, and the vehicle turn signal is controlled to flash at a faster frequency to remind the user to check the vehicle turn signal circuit. By selecting different calibration current ranges under different system voltages, it can avoid misjudgment of faults caused by changes in system voltage, and improve the detection accuracy of the vehicle turn signal circuit.

[0031] In an optional embodiment, the above-mentioned calibration current mapping table is obtained by the tester through multiple tests. The vehicle turn signal includes: front turn signal, side turn signal and rear turn signal, and the three turn signal circuits are connected in parallel. When the circuit of any turn signal starts, the total resistance in the circuit increases and the feedback current will decrease. Among them, the power of the rear turn signal circuit is the smallest and the resistance is the largest. When the rear turn signal circuit is open, the impact on the feedback current of the entire circuit is the smallest. Therefore, the tester can only test the rear turn signal. If the open circuit of the rear turn signal can be correctly identified, the open circuit faults of the front turn signal and the rear turn signal can be identified for sure. Through experimental simulation, the tester tests the normal operation and fault status of the rear turn signal under different voltage conditions, and measures the peak value and stable value of the feedback current in the corresponding state.

[0032] The specific testing process is as follows: The 9-16V system voltage is divided into 70 parts, and the feedback current when the vehicle turn signal is working normally and the feedback current when the rear turn signal is open are collected every 0.1V. Optionally, 9-16V and 70 parts are only exemplary descriptions. In actual testing, the tester can also select other system voltage values ​​and other numbers. Here, in the state where the turn signal is working normally or the rear turn signal is open, the feedback current fluctuates within the corresponding range, so the peak value and the stable value in each state are taken as the floating current. Among them, the fluctuation range of the feedback current when the vehicle turn signal is working normally can be regarded as the first current interval, and the fluctuation range of the feedback current when the rear turn signal is open can be regarded as the second current interval. For any system voltage, the tester can determine a corresponding preset current interval based on the collected first current interval and second current interval. Each system voltage and the corresponding preset current interval can be stored in the calibration current mapping table as a set of mapping relationships.

[0033] For example, when the system voltage is 10V, the feedback current fluctuation range is 15-18A (first current interval) when the vehicle turn signal is working normally, and the feedback current fluctuation range is 10-13A (second current interval) when the rear turn signal is open. The tester can set the preset current interval corresponding to 10V to 14-19A. Later, during the vehicle driving process, if the vehicle controller detects that the system voltage is 10V and the feedback current is less than 14A, it can be determined that there is an open circuit fault in the vehicle turn signal circuit, and the vehicle turn signal is controlled to flash at the first frequency.

[0034] The above process only collects the fault current when the rear turn signal lamp is open-circuited, instead of collecting the fault current when each turn signal lamp is disconnected, thus reducing the workload.

[0035] The mapping relationship between the preset voltage and the preset current range can be referred to Figure 2 As shown, during the vehicle driving process, after the vehicle controller obtains the system voltage, it first determines the target preset voltage matching the current system voltage based on the preset algorithm, and then determines the preset current interval corresponding to the target preset voltage as the calibration current interval. For example, the system voltage obtained by the vehicle controller is 9180mV, and the system voltage is calculated as follows: (9180-9000) / 100, which can be obtained as 1.8, which is rounded to 2. Then the target preset voltage matching 9180mV is 9200mV, that is, 9.2V, and the current interval 3 corresponding to 9.2V is the calibration current interval.

[0036] Through the above process, the vehicle controller can select a more appropriate calibrated current range for open circuit detection when the system voltage changes, making the vehicle turn signal circuit detection more accurate and effectively reducing the probability of misjudgment of faults.

[0037] In an optional embodiment, the vehicle turn signal circuit may be configured with an open circuit feedback line to indicate whether the vehicle turn signal circuit is in an open circuit state. Specifically, the open circuit feedback line is used to detect whether the physical connection of the turn signal circuit is intact. If the circuit is broken or has poor contact, the open circuit feedback line will not be connected, thereby triggering an open circuit signal. The open circuit feedback line ensures that the detected fault is indeed due to a line problem and not other factors. If the vehicle turn signal circuit is configured with an open circuit feedback line, the vehicle controller will comprehensively determine the state of the vehicle turn signal circuit based on the open circuit feedback line and the feedback current.

[0038] Specifically, the vehicle turn signal can be divided into multiple parts such as the front turn signal, the side turn signal and the rear turn signal. If all parts of the vehicle turn signal are equipped with open-circuit feedback lines, the vehicle determines whether the circuit of the vehicle turn signal is in an open-circuit state only based on the signal output by the open-circuit feedback line. If the vehicle turn signal part is equipped with an open-circuit feedback line (for example, the front turn signal is equipped with an open-circuit feedback line, and the rear turn signal is not equipped with an open-circuit feedback line), the vehicle controller can comprehensively determine the circuit state based on the open-circuit feedback line and the feedback current. If the vehicle turn signal is not equipped with an open-circuit feedback line, the vehicle turn signal determines the circuit state only based on the feedback current.

[0039] Figure 3 A flow chart of another turn signal control method provided in an embodiment of the present application. Figure 3 As shown, it may specifically include: In step 301 , the vehicle controller detects whether all vehicle turn signals are equipped with open-circuit feedback lines. If so, the process proceeds to step 306 , otherwise, the process proceeds to step 302 .

[0040] In step 302 , the vehicle controller detects whether the vehicle turn signal lamp is partially configured with an open feedback line. If so, the process proceeds to step 305 , otherwise, the process proceeds to step 303 .

[0041] In step 303 , the vehicle controller detects whether the feedback current is abnormal. If so, the process proceeds to step 304 , otherwise, the process proceeds to step 307 .

[0042] Step 304, controlling the vehicle turn signal lamp to flash at a first frequency.

[0043] Step 305 , whether an open-circuit signal is detected through the open-circuit feedback line, if so, proceed to step 304 , otherwise proceed to step 303 .

[0044] Step 306 , whether an open-circuit signal is detected through the open-circuit feedback line, if so, proceed to step 304 , otherwise proceed to step 307 .

[0045] Step 307, controlling the vehicle turn signal lamp to flash at a second frequency.

[0046] In the scenario where all the circuits of the vehicle turn signal lamp are equipped with open-circuit feedback lines, the vehicle controller determines the circuit status only through the open-circuit feedback lines. If an open-circuit signal is detected, the circuit is determined to be abnormal, and the process directly proceeds to step 304 to control the vehicle turn signal lamp to flash at a first frequency. If no open-circuit signal is detected, the circuit is determined to be fault-free, and the process directly proceeds to step 307 to control the vehicle turn signal lamp to flash at a second frequency. The second frequency can be regarded as the normal flashing frequency of the vehicle turn signal lamp, and the first frequency is usually greater than the second frequency. For example, the first frequency can be set to twice, three times, or other reasonable values ​​of the second frequency.

[0047] In a scenario where part of the circuit of the vehicle turn signal lamp is configured with an open-circuit feedback line, the vehicle controller may first determine the circuit state based on the open-circuit feedback line, and then determine the circuit state through the feedback current. For example, when only the front turn signal lamp is configured with an open-circuit feedback line, the vehicle controller first determines whether the front turn signal lamp is open based on the open-circuit feedback line. If no open-circuit signal is detected, it can be preliminarily determined that the front turn signal lamp is not faulty. Afterwards, the vehicle controller determines the circuit state of the rear turn signal lamp and other parts based on the feedback current, and repeatedly verifies the circuit state of the front turn signal lamp. If neither the open-circuit feedback line nor the feedback current detects an abnormality, the vehicle controller may determine that the circuit is not faulty and proceeds to step 307. If either the open-circuit feedback line or the feedback current detects an abnormality, the vehicle controller determines that the circuit is abnormal and proceeds to step 304.

[0048] In the scenario where the vehicle turn signal lamp is not equipped with an open-circuit feedback line, the vehicle controller detects the circuit state only through the feedback current in step 303. If the feedback current is abnormal, the circuit is determined to be abnormal and the process goes to step 303; otherwise, the circuit is determined to be normal and the process goes to step 307.

[0049] By combining the open-circuit feedback line and the feedback current, the accuracy of circuit state detection can be further improved, thereby reducing the probability of misjudgment of vehicle turn signal failure.
