[0051] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention 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 interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, any variation of the terms "including" and "having" is 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 clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0053] Figure 1 is a flow chart of a first method for controlling a reversing fill light according to an embodiment of the present invention. Figure 2 1 is a control system diagram of a reversing fill light according to an embodiment of the present invention. This embodiment is applicable to mining areas, coal yards, etc. where nighttime work is required and reversing is required under poor lighting conditions. The method can be executed by a control device for a reversing fill light. Figure 1 As shown, the method includes:

[0054] S110: Obtain vehicle status information.

[0055] Specifically, Figure 2 As shown, the vehicle status information includes the gear status of the vehicle, and the gear status of the vehicle can be a forward gear status, a reverse gear status, a neutral gear status, and a parking gear status. The control system of the reverse fill light includes a control module 1 and a gear lever position sensor 2. The gear lever position sensor 2 is installed on the vehicle transmission to monitor the gear status of the vehicle. The control module 1 obtains the gear status of the vehicle by connecting with the gear lever position sensor 2.

[0056] S120: Acquire ambient brightness when the vehicle is in a reverse gear state.

[0057] Specifically, Figure 2 As shown, the ambient brightness refers to the intensity of natural light, for example, the natural light intensity is high during the day and low at night. The control system of the reversing fill light also includes a photosensitive device 3, which can be a photoresistor and a photodiode. The photosensitive device 3 can be installed outside the vehicle to sense the ambient brightness. The control module 1 is connected to the photosensitive device 3 to obtain the ambient brightness when the vehicle is in the reverse gear state.

[0058] S130: Control the working state of the fill light at least according to the ambient brightness and the preset value of the fill light.

[0059] Specifically, Figure 2As shown, the preset value of the fill light 4 refers to the preset threshold of the fill light 4. The working state of the fill light 4 includes the on, off and light intensity of the fill light 4. The control module 1 is connected to the fill light 4, and the control module 1 analyzes the ambient brightness and the preset value of the fill light 4 to form a control signal and output it to the fill light 4, so as to control the on, off and light intensity of the fill light 4.

[0060] In the embodiment of the present invention, the vehicle status information is first obtained, and the ambient brightness is obtained when the vehicle is in the reverse gear state. Furthermore, the working state of the fill light is controlled at least according to the ambient brightness and the preset value of the fill light. The above technical solution can automatically adjust the illumination intensity of the reversing fill light in the case of poor light at night to provide the best ambient brightness for drivers working at night, so that the driver can understand the reversing road conditions and improve driving safety.

[0061] Figure 3 1 is a flow chart of a second method for controlling a back-up fill light according to an embodiment of the present invention. The embodiment of the present invention further describes controlling the working state of the fill light according to at least the ambient brightness and the preset value of the fill light. Figure 3 As shown, the control method includes:

[0062] S210: Obtain vehicle status information.

[0063] S220: Acquire the ambient brightness when the vehicle is in the reverse gear state.

[0064] S230: When the ambient brightness is lower than the preset value, the fill light is controlled to be in the on state.

[0065] Specifically, an environment brightness is pre-stored in the control module 1 as a preset value for turning on the fill light 4, and the environment brightness may be the night environment brightness. At this time, when the environment brightness is lower than the preset value, it means that it is night, and the environment brightness is low at night. The driver cannot see the work site clearly due to insufficient light, so it is necessary to control the fill light 4 to turn on for fill light, thereby helping the driver to obtain the best reversing vision.

[0066] When the ambient brightness is higher than the preset value, that is, during the day, the natural light intensity is high and the light is sufficient, so there is no need to turn on the fill light 4, and the fill light 4 is in the off state.

[0067] The embodiment of the present invention compares the ambient brightness with the pre-stored preset value for turning on the fill light after the ambient brightness is obtained. When the ambient brightness is less than the preset value for turning on the fill light, the fill light is automatically controlled to turn on for fill light, thereby helping the driver to obtain the best reversing field of view and improving the driver's reversing safety.

[0068] Figure 41 is a flow chart of a third method for controlling a back-up fill light according to an embodiment of the present invention. The embodiment of the present invention further describes controlling the working state of the fill light at least according to the ambient brightness and the preset value of the fill light. Figure 4 As shown, the control method includes:

[0069] S310: Obtain vehicle status information.

[0070] S320: Acquire the ambient brightness when the vehicle is in the reverse gear state.

[0071] S330: Calculate the difference between the ambient brightness and the preset value.

[0072] Specifically, the control module 1 can process and calculate the data, and after obtaining the ambient brightness and the startup preset value, calculate the difference between the ambient brightness and the startup preset value to obtain the difference between the ambient brightness and the startup preset value.

[0073] S340: Determine a lighting duty cycle according to the difference to control the brightness of the fill light.

[0074] Specifically, the lighting duty cycle, that is, the proportion of the power-on time relative to the total time in a pulse cycle, is a key parameter used to adjust the brightness of the lighting device in the pulse width modulation technology. Different differences correspond to different lighting duty cycles, and the difference is positively correlated with the lighting duty cycle. The larger the difference, the larger the lighting duty cycle, and conversely, the smaller the difference, the smaller the lighting duty cycle. The lighting duty cycle can be determined accordingly based on the difference. The control module 1 controls the brightness of the fill light 4 by adjusting the lighting duty cycle. When the lighting duty cycle increases, it means that within a cycle, the proportion of the time that the fill light 4 is powered on increases, thereby increasing the average current, resulting in an increase in the brightness of the headlight. Conversely, when the lighting duty cycle decreases, it means that within a cycle, the proportion of the time that the fill light 4 is powered on decreases, thereby reducing the average current, resulting in a decrease in the brightness of the fill light 4.

[0075] In the embodiment of the present invention, the difference between the ambient brightness and the preset value is calculated, and the lighting duty cycle is further determined according to the difference to control the brightness of the fill light. Automatic regulation of the brightness of the fill light is achieved, so that the fill light can adaptively adjust the brightness of the fill light under different ambient lighting conditions to further provide the driver with suitable lighting conditions and improve the driver's reversing safety.

[0076] Figure 5 4 is a flow chart of a fourth method for controlling a reversing fill light provided according to an embodiment of the present invention. Figure 6 2 is a control system diagram of a second type of back-up fill light provided according to an embodiment of the present invention. In this embodiment of the present invention, a new step is added to further illustrate the adaptive adjustment function of the fill light. Figure 5As shown, the method includes:

[0077] S410: Obtain vehicle status information.

[0078] S420: Acquire the ambient brightness when the vehicle is in the reverse gear state.

[0079] S430: Control the working state of the fill light at least according to the ambient brightness and the preset value of the fill light.

[0080] S440: Obtain the lighting mode required by the driver.

[0081] Specifically, Figure 6 As shown, the control system of the reversing fill light also includes a human-computer interaction module 5. Since the optimal visual brightness of different drivers is different, the human-computer interaction module 5 can be installed on the central control instrument panel. Through the human-computer interaction module 5, the driver can adjust the lighting mode according to his own needs. The control module 1 is connected to the human-computer interaction module 5 to obtain the lighting mode required by the driver.

[0082] S450, adjusting the brightness level of the fill light according to the required lighting mode.

[0083] The following is a detailed description of adjusting the brightness level of the fill light according to the required lighting mode.

[0084] The optional demand lighting module includes at least two demand lighting modes, and the brightness level includes at least two brightness levels; adjusting the brightness level of the fill light according to the demand lighting mode includes: when the demand lighting mode is a first-level lighting mode, determining the brightness level of the fill light to be a first brightness level; when the demand lighting mode is a second-level lighting mode, determining the brightness level of the fill light to be a second brightness level; wherein the brightness of the first brightness level is less than the brightness of the second brightness level.

[0085] Specifically, the required lighting modes may include at least two, a primary lighting mode and a secondary lighting mode, and the brightness levels of the fill light 4 also include at least two. The primary lighting mode is a strong light lighting mode, and the secondary lighting mode is a weak light lighting mode. The driver can choose according to the needs. The primary lighting mode corresponds to the first brightness level, and the secondary lighting mode corresponds to the second brightness level. The fill light 4 corresponding to the first brightness level is high, and the fill light 4 corresponding to the second brightness level is low. When the driver feels that the light brightness is not enough and cannot see the reversing road conditions clearly, the primary lighting mode can be selected to control the fill light 4 to the first brightness level. When the driver feels that the brightness of the fill light 4 is too bright, the secondary lighting mode can be selected to control the fill light 4 to the second brightness level.

[0086] It is understandable that a third lighting mode can be added. The third lighting mode corresponds to the third brightness level of the fill light 4. This brightness level is a medium light intensity. At this light intensity, the driver's field of vision can be maintained clear, and the problem of glare can be avoided, thereby improving the driver's driving experience.

[0087] The embodiment of the present invention obtains the required lighting mode of the driver and adjusts the brightness level of the fill light according to the required lighting mode, thereby providing the driver with field of vision brightness and meeting the requirements of different drivers for optimal field of vision brightness, thereby ensuring the driver's reversing safety and improving the driver's driving experience.

[0088] Figure 7 4 is a flow chart of a fifth method for controlling a reversing fill light provided according to an embodiment of the present invention. Figure 8 4 is a control system diagram of a third type of reversing fill light provided according to an embodiment of the present invention. Fig. 9 It is a schematic diagram of an illumination angle of a fill light provided according to an embodiment of the present invention. Fig.10 is a schematic diagram of another irradiation angle of a fill light provided according to an embodiment of the present invention. The embodiment of the present invention further describes controlling the working state of the fill light according to at least the ambient brightness and the start-up preset value of the fill light. Figure 7 As shown, the method includes:

[0089] S510: Obtain vehicle status information.

[0090] S520: Acquire the ambient brightness when the vehicle is in the reverse gear state.

[0091] S530, controlling the illumination angle of the fill light according to the ambient brightness, the preset value of the fill light, and the reversing road condition;

[0092] The illumination angle is the angle between the illumination path and the direction perpendicular to the ground.

[0093] Specifically, Figure 8 As shown, the reversing road condition refers to the pothole degree of the vehicle's reversing route and the reversing distance, etc. The control system of the reversing fill light also includes a camera 6, which can be installed at the rear of the vehicle to collect road condition images behind the vehicle. The control module 1 is connected to the camera 6 to obtain the reversing road condition when the vehicle is in a gear position.

[0094] The following is a further detailed description of controlling the illumination angle of the fill light according to the ambient brightness, the preset value of the fill light, and the reversing road condition.

[0095] The illumination angle of the fill light can be optionally controlled according to the ambient brightness, the preset value of the fill light and the reversing road conditions, including: when the ambient brightness is lower than the preset value and the distance between the vehicle and the reversing end point is a first distance, the fill light is controlled to illuminate at a first illumination angle; when the ambient brightness is lower than the preset value and the distance between the vehicle and the reversing end point is a second distance, the fill light is controlled to illuminate at a second illumination angle; wherein the first distance is greater than the second distance, and the first illumination angle is greater than the second illumination angle.

[0096] Specifically, Fig. 9 and Fig.10 As shown, the larger angle between the illumination path c1 and the vertical ground direction -Z is a1, and the smaller angle between the illumination path c2 and the vertical ground direction -Z is a2. When the vehicle is reversing at night, the reversing road conditions are acquired, and the control module analyzes the reversing road conditions and the distance between the vehicle and the reversing end point. When the distance between the vehicle and the reversing end point is a relatively long first distance b1, the fill light 4 needs to illuminate the relatively long distance, so that the driver can see a farther distance. Therefore, the angle of the fill light 4 is controlled to illuminate at a relatively large first illumination angle a1. When the distance between the vehicle and the reversing end point is a relatively short second distance b2, the fill light 4 needs to illuminate the part close to the vehicle, so that the driver can see the road conditions at a relatively short distance from the vehicle more clearly. Therefore, the angle of the fill light 4 is controlled to illuminate at a relatively small second illumination angle a2.

[0097] Fig.11 1 is a flow chart of a sixth method for controlling a back-up fill light according to an embodiment of the present invention. The embodiment of the present invention illustrates that the fill light can also be used as a fault light to flash when a vehicle fails. Fig.11 As shown, the method includes:

[0098] S510: Obtain vehicle status information.

[0099] S520: Acquire the ambient brightness when the vehicle is in the reverse gear state.

[0100] S530: Control the working state of the fill light at least according to the ambient brightness and the preset value of the fill light.

[0101] S540: When the vehicle is in a fault state, the fill light is controlled to be turned on and flashing.

[0102] Specifically, the vehicle status information includes a fault status. When a vehicle fails, the fill light 4 can be controlled to flash as a fault light to alert surrounding vehicles, thereby further improving the safety of the driver driving the vehicle.
