[0001] The present invention relates to automobile lamps, and in particular to a steering running lamp fault processing system. In addition, the present invention also relates to an automobile lamp system and a vehicle. Background Art
[0002] Among existing vehicle lights, corner lights are lamps that provide auxiliary lighting for the corners of the road in front of the vehicle or for the side or rear of the vehicle. Corner lights can play a certain auxiliary lighting role when the road environment lighting conditions are insufficient, providing a guarantee for driving safety. At the same time, corner lights can also play a certain auxiliary lighting role in areas where the road environment lighting conditions are insufficient.
[0003] In existing headlights, in order to save manufacturing costs, corner lights are often combined with other lamps. Although this can save costs, in actual use, the illumination angle is limited and cannot meet the requirements for corner lights in actual use. In addition, when combined with other lamps, the performance and operational safety of the corner lights are reduced. Summary of the invention
[0004] The first problem to be solved by the present invention is to provide a steering running light fault processing system, which has a simple structure, convenient operation and high safety performance.
[0005] In addition, the problem that the present invention also aims to solve is to provide a vehicle, wherein the steering running light fault processing system of the vehicle has a simple structure, convenient operation and high safety performance.
[0006] In order to solve the above technical problems, the present invention provides a turn signal light fault handling system, including a control unit, which is electrically connected to the turn signal light for reading the fault mark status of the turn signal light and marking the fault signal; an alarm unit, which is electrically connected to the control unit and prompts the fault signal according to the control of the control unit.
[0007] As a preferred embodiment, the control unit is configured to read the status of the fault flag in the following manner: if the fault flag is 1, a fault occurred in the last lighting cycle of the turn running lights, all the turn running lights are lit in this lighting cycle, and it is detected whether a fault occurs in this lighting cycle of the turn running lights; if the fault flag is not 1, the turn running lights execute the flowing mode normally, and it is detected whether a fault occurs in this lighting cycle of the turn running lights.
[0008] As another preferred embodiment, the control unit is configured that if it is detected that the turn signal lights in this lighting cycle have a fault, the fault flag is 1, and all the turn signal lights are controlled to be extinguished, and the control unit controls the alarm unit to prompt a fault signal; if it is detected that the turn signal lights in this lighting cycle have no fault, the fault flag is 0, and the control unit controls all the turn signal lights to keep operating.
[0009] More preferably, the control unit is an MCU.
[0010] As a specific implementation, the alarm unit is an alarm light.
[0011] As another specific implementation, the turn signal light is a front turn signal light or a rear turn signal light.
[0012] More specifically, the turn signal light is an LED turn signal light.

[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] like Figure 1 As shown, the present invention provides a steering running light fault processing system, comprising:
[0025] A control unit 1, the control unit 1 is electrically connected to the turn signal lamp 3, so as to read the fault mark state of the turn signal lamp 3 and mark the fault signal;
[0026] The alarm unit 2 is electrically connected to the control unit 1 and prompts a fault signal according to the control of the control unit 1.
[0027] In a specific embodiment of the present invention, Figure 2 As shown, the control unit 1 is configured to read the status of the fault flag in the following manner: if the fault flag is 1, a fault occurred in the last lighting cycle of the steering running lights 3, all the steering running lights 3 are lit in this lighting cycle, and it is detected whether a fault occurs in this lighting cycle of the steering running lights 3; if the fault flag is not 1, the steering running lights 3 execute the running mode normally, and it is detected whether a fault occurs in this lighting cycle of the steering running lights 3.
[0028] Furthermore, the control unit 1 is configured such that if it is detected that the turn signal lamp 3 within the current lighting cycle has a fault, the fault flag is 1, and all the turn signal lamps 3 are controlled to be extinguished, and the control unit 1 controls the alarm unit 2 to prompt a fault signal; if it is detected that the turn signal lamp 3 within the current lighting cycle has no fault, the fault flag is 0, and the control unit 1 controls all the turn signal lamps 3 to remain in operation.
[0029] The following Figure 2The flowchart shown in the figure illustrates the fault handling process within one lighting cycle of the steering running light fault handling system of the present invention:
[0030] In this lighting cycle, control unit 1 first reads the status of the fault flag in the previous lighting cycle:
[0031] First, if the fault flag in the last lighting cycle read by the control unit 1 is 1, it is considered that a fault occurred in the last lighting cycle, and then all the turn-by-turn running lights 3 are first lit in this lighting cycle;
[0032] Next, the turn signal lights 3 in this lighting cycle are tested again to confirm whether there is still a fault: if the control unit 1 detects that there is no fault, the fault flag is marked as 0, and the turn signal lights 3 can normally execute the constant lighting mode; if the control unit 1 detects that there is a fault, the fault flag is marked as 1, the alarm unit 2 sounds an alarm, and all the turn signal lights 3 are extinguished.
[0033] It can be seen from here that if the fault flag in the last lighting cycle read by the control unit 1 is 1, in order to avoid the situation where the turn signal lamp 3 is partially or completely extinguished, the turn signal lamp 3 can be fully illuminated first, and while being illuminated, it is continuously detected whether the turn signal lamp 3 is still faulty. This processing method can ensure that when a fault in the turn signal lamp 3 has been detected, the turn signal lamp 3 will not be partially or completely extinguished, thereby ensuring the aesthetic performance of the headlight, and will not affect the aesthetics of the headlight when a fault in the turn signal lamp 3 is detected, and the faulty part will not be illuminated, while the part without the fault will be illuminated.
[0034] Secondly, if the fault flag read by the control unit 1 in the last lighting cycle is 0, it means that there is no fault in the last lighting cycle, and the steering running light 3 executes the running mode normally. Then, another test will be performed in this lighting cycle. As for the test results, if a fault is detected, the fault flag is marked as 1, and the alarm unit 2 sounds an alarm and turns off all the steering running lights 3; if there is no fault, the fault flag is marked as 0, and the steering running lights 3 continue to execute the running mode.
[0035] According to the above description, it can be seen that the turn signal light fault handling system of the present invention has the following advantages: First, in the turn signal light fault handling system of the present invention, the control unit 1 will read the fault flag in the last lighting cycle. If the fault flag read by the control unit 1 for the first time is 1, it means that there was a fault in the last lighting cycle. The control unit 1 will control the turn signal lights 3 to be fully lit in this lighting cycle, and will not cause some turn signal lights 3 to not light up due to the detection of a fault. A second detection will be performed immediately afterwards. If the second detection still finds that there is a fault, the fault flag will be marked as 1, the alarm unit 2 will sound an alarm, and the turn signal lights 3 will all be extinguished. If the result of the second detection is that there is no fault, the previous fault flag will be cleared, and the fault flag will be re-marked as 0, and the turn signal lights 3 will execute the always-on action mode. Second, if the fault flag read by the control unit 1 for the first time is 0, it means that there was no fault in the last lighting cycle, and the turn signal light 3 in this lighting cycle executes the running mode normally. At the same time, the turn signal light 3 will be tested for the second time. If a fault is detected in the second time, the fault flag will be marked as 1, and the alarm unit 2 will sound an alarm, and the turn signal light 3 will all be extinguished; if the result of the second test is that there is no fault, the fault flag will continue to be marked as 0, and the turn signal light 3 will execute the running mode.
[0036] It can be understood here that the control unit 1 may have inaccurate detection during the detection process due to various reasons. The steering running light fault processing system of the present invention takes this situation into consideration and defaults to clearing the fault mark 1 detected in the previous detection when the second detection is correct, so as to ensure the normal operation of the steering running light 3. The steering running light fault system of the present invention will re-detect the situation where the last fault mark is 1. If the fault mark is 1, the control unit 1 will control the alarm unit 2 to alarm the driver, indicating that the steering running light 3 has a fault. If the steering running light 3 is found to be fault-free after the re-detection, the previous fault mark 1 will be cleared and the fault mark will be recorded as 0, so that the steering running light 3 can perform the normal constant light action in the subsequent process.
[0037] As a preferred embodiment of the present invention, the control unit 1 is an MCU. MCU is a microcontroller unit, also known as a single-chip microcomputer or a single-chip microcomputer. It appropriately reduces the frequency and specifications of the central processing unit, and integrates peripheral interfaces such as memory, counter, USB, A / D conversion, UART, PLC, DMA, and even LCD drive circuits on a single chip to form a chip-level computer, which performs different combination controls for different applications. MCU can accurately, quickly and efficiently perform pre-specified tasks, and can achieve intelligent control functions, thereby meeting the control requirements of the steering running light fault processing system of the present invention. It should be noted that the built-in program and function implementation of the control unit of the present invention can be realized through a variety of mature logic predictions, such as PLC control language, C language, etc. The uniqueness of the present invention lies in the formation of a modular unit implementation of the steering running light fault processing system, and the safety of the steering running light is improved through the combination of functions.
[0038] As another preferred embodiment of the present invention, the alarm unit 2 may be a warning light, which can give a warning indication to the driver when the control unit 1 detects a fault.
[0039] As another preferred embodiment of the present invention, the turn signal light 3 is a front turn signal light or a rear turn signal light.
[0040] More preferably, the turn signal light 3 is an LED turn signal light.
[0041] In addition, the present invention also provides a vehicle lamp system, including a turn signal lamp fault processing system according to any one of the above technical solutions.
[0042] Furthermore, the present invention also provides a vehicle having a vehicle lighting system according to the above technical solution.
[0043] It can be seen from the above description that the steering running light fault processing system of the present invention includes a control unit 1 and an alarm unit 2. The control unit 1 is electrically connected to the steering running light 3 to read the fault sign state of the steering running light 3 and mark the fault signal; the alarm unit 2 is electrically connected to the control unit 1 and prompts the fault signal according to the control of the control unit 1. The steering running light fault processing system of the present invention reads the fault sign through the control unit 1 and marks the fault sign, and then realizes the fault safety processing of the steering running light 3 by analyzing the fault sign, which better meets the user experience and can timely alarm the alarm unit 2, greatly improving the safety of the steering running light.
