[0040] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field under the enlightenment of the embodiments belong to the scope of protection of the present application.

[0042] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] At present, with the development of the automobile industry, the use of high-mounted brake lights can effectively reduce the possibility of rear-end collisions and improve the safety performance of automobiles. However, when working, high-mounted brake lights will be affected by the external environment, so their brightness will change, and even flicker, which will seriously affect the driver's judgment of road conditions. Therefore, changes in the brightness of high-mounted brake lights and flickering may cause traffic accidents.

[0044] In the prior art, in order to prevent the brightness of the high-mounted brake lights from changing and flickering, there are detailed records of the brightness changes, flickering causes and solutions of the high-mounted brake lights of fuel vehicles, but there are no detailed records of the testing and treatment methods of the high-mounted brake lights of new energy vehicles. However, the structures of new energy vehicles and fuel vehicles are not exactly the same, and the specific parameters that affect the high-mounted brake lights are different. Therefore, the method of applying the technical parameters of fuel vehicles to solve the brightness changes and flickering of the high-mounted brake lights of new energy vehicles is not applicable.

[0045] In order to solve the above problems, the concept of the present application is to accurately locate the factors that cause the abnormality of the high-mounted brake light.

[0046] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0047] Figure 1 This is a test system structure diagram based on a method for handling abnormalities of a high-mounted brake light provided in this application, such as Figure 1 As shown, the test system mainly includes: a waveform generator 101, a power module 102 and a high-mounted brake light 103. The waveform generator can control the wave parameters including but not limited to: waveform frequency, amplitude, peak value, deviation value, rise time and waveform duration.

[0048] Figure 2 This is a flow chart of a first embodiment of a method for handling abnormalities of a high-mounted brake light provided by the present application. Figure 2 , the processing method includes:

[0049] Step S201: In a test system constructed based on the high-mounted brake lamp to be tested, an initial ripple test process is performed on the high-mounted brake lamp to be tested to obtain theoretical interference parameters in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state.

[0050] In this embodiment, a test system for a high-mounted brake light is established (specifically, it can be Figure 1 As shown in the figure, in order to match the experimental environment with the actual situation, that is, to ensure that the high-mounted brake light can maintain normal working conditions under normal conditions, for example, the test system can be tested in a shielded room, the indoor temperature of the shielded room can be around 25°C, and the indoor humidity can be below 80%.

[0051] In addition, in order to further match the actual situation, in the test system, an AC superimposed ripple is used to perform an abnormal test on the high-mounted brake lamp to be tested. By changing at least one of the above-mentioned key parameters in the AC superimposed ripple, and outputting the AC superimposed ripple to the high-mounted brake lamp through the waveform generator 101 and the power supply module 102, it is determined whether the high-mounted brake lamp will be in an abnormal state under the ripples of different key parameters, so that the key parameters in the ripples corresponding to the abnormal state are used as theoretical interference parameters.

[0052] Step S202: In the constructed vehicle environment, a verification ripple test is performed on the high-mounted brake lamp to be tested to obtain actual interference parameters in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state.

[0053] In this embodiment, the constructed vehicle environment mainly includes: a battery management system (Battery Management System; referred to as: BMS), a power distribution system (Power Distribution Module) connected to the BMS, a DC-DC converter connected to the power distribution system, and a high-mounted brake light connected to the DC-DC converter.

[0054] By changing at least one of the above key parameters in the AC superimposed ripple, the DC-DC converter inputs its corresponding ripple into the high-mounted brake light to determine whether the high-mounted brake light will be in an abnormal state under the ripples of different key parameters, thereby taking the key parameters in the ripple corresponding to the abnormal state as the actual interference parameters.

[0055] Step S203: According to the theoretical interference parameter and the actual interference parameter, obtain the final interference parameter in the ripple corresponding to the abnormality of the high-mounted brake light.

[0056] In this embodiment, for example, if the theoretical interference parameter is consistent with the actual interference parameter, the theoretical interference parameter is used as the final interference parameter in the ripple corresponding to the abnormality of the high-mounted brake lamp.

[0057] In this embodiment, an initial ripple test process is performed on the high-mounted brake light to be tested in a test system built based on the high-mounted brake light to be tested, so as to obtain theoretical interference parameters in the ripple corresponding to the abnormal state of the high-mounted brake light to be tested; then, in the built whole vehicle environment, a verification ripple test process is performed on the high-mounted brake light to be tested, so as to obtain actual interference parameters in the ripple corresponding to the abnormal state of the high-mounted brake light to be tested; then, based on the theoretical interference parameters and the actual interference parameters, the final interference parameters in the ripple corresponding to the abnormal state of the high-mounted brake light are obtained. Compared with the prior art in which it is impossible to know the interference factors that cause the abnormality of the high-mounted brake light in the new energy vehicle, the present application tests the theoretical interference parameters that cause the abnormality of the high-mounted brake light in the new energy vehicle through the test system, and then further verifies them in the built whole vehicle environment to obtain the corresponding actual interference parameters, so as to accurately locate the final interference parameters based on the theoretical interference parameters and the actual interference parameters, thereby effectively and conveniently locating the interference parameters that interfere with the abnormality of the high-mounted brake light of the new energy vehicle.

[0058] Figure 3 This is a flow chart of a second embodiment of a method for handling abnormalities of a high-mounted brake light provided in this application. Figure 2 Based on the embodiment shown, see Figure 3 A specific implementation of step S201 is:

[0059] Step S301, control the waveform generator and the modulated power supply in the test system to output a plurality of first simulated ripples to the high-mounted brake lamp to be tested, so as to obtain theoretical interference parameters in the ripples corresponding to when the high-mounted brake lamp to be tested is in an abnormal state.

[0060] In this embodiment, if Figure 1 As shown, the waveform generator is connected to a modulated power supply, the modulated power supply is connected to the high-mounted brake lamp to be tested, the waveform generator and the modulated power supply in the test system are controlled, and multiple first simulated ripples (i.e., the above-mentioned AC superimposed ripples) are output to the high-mounted brake lamp to be tested, so as to obtain the theoretical interference parameters in the ripples corresponding to the abnormal state of the high-mounted brake lamp to be tested.

[0061] For example, during the test, when the key parameter in the AC superimposed ripple is the frequency parameter, the high-mounted brake light has no obvious brightness change when the frequency is 0-40kHz, and when it is 40kHz, the brightness of the high-mounted brake light begins to change, indicating that it is in an abnormal state. The brightness of the high-mounted brake light changes when the frequency is 40kHz-96kHz, and when it is 96kHz, the high-mounted brake light flickers, indicating that it is in an abnormal state. Based on this, it can be determined that between 40kHz and 96kHz, and including 40kHz and 96kHz, are interference theory interference parameters.

[0062] Accordingly, a specific implementation of step S202 includes:

[0063] Step S302, controlling the first test point in the vehicle environment to output a plurality of second simulated ripples to the high-mounted brake lamp to be tested, so as to obtain a first actual interference parameter in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state;

[0064] The first test point is set at the DC-DC converter, and an external signal generator and an external power supply are superimposed on the DC-DC converter as the actual power supply.

[0065] Optionally, the method may further include:

[0066] Step S303, controlling the second test point in the vehicle environment to output a plurality of third simulated ripples to the high-mounted brake lamp to be tested, so as to obtain a second actual interference parameter in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state;

[0067] The second test point is arranged at the battery that supplies power to the high-mounted brake lamp to be tested, and an external signal generator and an external power supply are superimposed on the battery as the actual power supply.

[0068] In this embodiment, combined with Figure 4 To illustrate, Figure 4 A schematic diagram of the structure of a high-mounted brake light vehicle environment provided in this application, such as Figure 4 As shown, in the vehicle environment, the first test point and the second test point are as follows Figure 4 Corresponding settings are made in (① represents the first test point; ② represents the second test point), that is, the first test point is set at the DC-DC converter; the second test point is set at the battery that supplies power to the high-mounted brake lamp to be tested. Then, multiple second simulated ripples can be output to the high-mounted brake lamp to be tested at the first test point, and / or multiple third simulated ripples can be output to the high-mounted brake lamp to be tested at the second test point to test the actual interference parameters corresponding to when the high-mounted brake lamp is in an abnormal state.

[0069] The abnormal state includes but is not limited to: flickering state and brightness change state, etc. The interference parameters include one or a combination of the following: waveform frequency, amplitude, peak value, deviation value, rise time and waveform duration.

[0070] It should be noted that in this embodiment, in the whole vehicle environment, the test is carried out using the waveform frequency as an example. If the actual interference parameters verified by the test are consistent with the theoretical interference parameters, the theoretical interference parameters can be used as the final interference parameters in the ripple corresponding to the abnormality of the high-mounted brake light.

[0071] In this embodiment, on the basis of the determination of the theoretical interference parameters, the corresponding first test point and / or second test point are set in the whole vehicle environment to test and verify the high-mounted brake light, so as to obtain the actual interference parameters in the whole vehicle environment that is more in line with the actual environment, and then determine the final interference parameters based on the theoretical interference parameters and the actual interference parameters, so as to more effectively and accurately determine the interference parameters that cause the high-mounted brake light to be in an abnormal state, and provide effective guidance for the subsequent resolution of the abnormal state.

[0072] Figure 5 This is a structural diagram of a first embodiment of an abnormality handling device for a high-mounted brake lamp provided in the present application, as shown in FIG. Figure 5 As shown, the processing device includes: a theoretical test module 51, a practical test module 52 and a processing module 53.

[0073] Among them, the theoretical test module 51 is used to perform initial ripple test processing on the high-mounted brake lamp to be tested in a test system built based on the high-mounted brake lamp to be tested, so as to obtain theoretical interference parameters in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state.

[0074] The actual test module 52 is used to perform a verification ripple test process on the high-mounted brake lamp to be tested in a vehicle environment, so as to obtain actual interference parameters in the ripple corresponding to when the high-mounted brake lamp to be tested is in an abnormal state.

[0075] The processing module 53 is used to obtain the final interference parameter in the ripple corresponding to the abnormality of the high-mounted brake light according to the theoretical interference parameter and the actual interference parameter.

[0076] In this embodiment, the processing device can perform the above Figure 2 or Figure 3 The implementation principle and benefits of the method shown are similar and will not be repeated here.

[0078] Among them, the abnormal processing device 63 of the high-mounted brake light triggers the test system 62 to use the initial ripple to test the high-mounted brake light to be tested, and obtains the theoretical interference parameters in the ripple corresponding to the abnormal state of the high-mounted brake light, and then triggers the whole vehicle environment 63 to continue to use the initial ripple to perform a verification test on the high-mounted brake light to be tested, and obtain the actual interference parameters, and then obtain the final interference parameters based on the theoretical interference parameters and the actual interference parameters.

[0080] The filter circuit includes: a plurality of filter capacitors; wherein the capacitance value of each filter capacitor is set based on the final interference parameter obtained in the abnormality handling method of the high-mounted brake lamp described in the above embodiment. And capacitors C2 and C3 with different values ​​are usually connected in parallel (such as Figure 7 As shown), a resonant relationship is formed to make the voltage lag behind the current, and the entire circuit has capacitance, which enables it to suppress a frequency band when used in the high-mounted brake light.

[0081] For example, when the final interference parameter is an AC superimposed ripple frequency of 96 kHz, the capacitance value of the filter capacitors C2 and C3 connected in parallel is 47 μF.
