Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of a vehicle tail lamp, a non-transitory computer-readable storage medium, a control device of a vehicle tail lamp, and a vehicle having the control device proposed according to an embodiment of the present invention are described below with reference to the drawings.
Fig. 1 is a flowchart of a control method of a vehicle tail lamp according to an embodiment of the present invention. As shown in fig. 1, the control method of the vehicle tail light of the embodiment of the present invention may include the steps of:
and S1, acquiring the illumination intensity behind the vehicle, and judging whether the illumination intensity is greater than a preset threshold value.
According to an embodiment of the present invention, the control method of the vehicle rear lamp further includes: acquiring the ambient light intensity, and judging whether the ambient light intensity is smaller than a preset intensity; and if the ambient illumination intensity is less than the preset intensity, acquiring the illumination intensity behind the vehicle.
Specifically, the ambient light intensity can be obtained in real time through a camera arranged outside the vehicle body, and the ambient light intensity is analyzed. When the ambient light intensity is less than the preset intensity, namely the vehicle runs in a dark place (for example, when the vehicle runs in a tunnel), or the vehicle runs at night, the light intensity behind the vehicle is obtained through a light intensity sensor arranged behind the vehicle, wherein the light intensity is used for indicating the light intensity and the illumination degree of the surface area of the object, and the unit is lux.
That is to say, before the illumination intensity behind the vehicle is acquireed, can acquire environment illumination intensity in real time through the camera that sets up outside the automobile body earlier, only when environment illumination intensity is less than preset intensity, just acquire the illumination intensity behind the vehicle through the illumination intensity sensor that sets up behind the vehicle to judge whether illumination intensity is greater than preset threshold value.
And S2, if the light intensity is larger than the preset threshold value, controlling the tail lamp of the vehicle at the preset low light intensity.
And S3, if the illumination intensity is less than or equal to the preset threshold value, controlling the tail lamp of the vehicle at the normal illumination intensity.
Specifically, although the vehicle tail light is mainly controlled by a driver through a switch or a brake operation at present, the vehicle tail light is only controlled to be turned on or off, and the light intensity of the vehicle tail light cannot be controlled. For example, when driving at night, a vehicle tail lamp (such as a rear lamp and a brake lamp, wherein the brake lamp is turned on when the vehicle brakes) needs to be turned on, and because the illumination intensity of the vehicle tail lamp cannot be adjusted and only has a fixed brightness, when the brightness is too high, a rear vehicle owner close to the rear vehicle owner will be dazzled, so that not only is the normal driving of the rear vehicle owner influenced, but also potential safety hazards are brought to the vehicle; if the brightness is too low, the driving prompting function cannot be generated for the distant vehicle.
Therefore, in the embodiment of the present invention, as shown in fig. 2, one or more illumination intensity sensors may be disposed behind the vehicle, the illumination intensity behind the vehicle is obtained by the illumination intensity sensors in real time, and the obtained illumination intensity is sent to the control module, so that the control module determines whether there is another vehicle behind the vehicle according to the illumination intensity behind the vehicle, and then controls the tail lights of the vehicle according to the determination result.
For example, the control module may be an illumination intensity adjusting module in a TCM (vehicle rear cabin distribution box), the illumination intensity sensor sends the detected illumination intensity information to the TCM, the illumination intensity adjusting module inside the TCM judges whether the detected illumination intensity information exceeds a set illumination intensity limit value according to the received illumination intensity information, and if the detected illumination intensity information exceeds the illumination intensity limit value, it indicates that a vehicle approaches behind the vehicle (a front illuminating lamp of the vehicle is turned on when the vehicle travels at night, and the illumination intensity detected by the illumination intensity sensor is stronger when the distance between the vehicles behind the vehicle is closer); if the light intensity limit value is not exceeded, it is indicated that no vehicle is approaching behind the vehicle. And then, the illumination intensity adjusting module controls and adjusts the tail lamp of the vehicle to different illumination intensities according to the judgment result.
Specifically, when the illumination intensity is greater than a preset threshold (i.e., the illumination intensity limit value is calibrated according to actual conditions), it is determined that another vehicle approaches the rear of the vehicle within a preset range, and at this time, the illumination intensity adjusting module controls the tail lamp of the vehicle with a preset low illumination intensity (the preset low illumination intensities corresponding to the back light and the stop light are different, for example, the back light may correspond to the preset low illumination intensity 1, the stop light may correspond to the preset low illumination intensity 2, and two different preset low illumination intensities may be set in the program); when illumination intensity is less than or equal to the preset threshold value, it is judged that no other vehicle is close to in the preset range of the rear of the vehicle, the illumination intensity adjusting module controls the tail lamp of the vehicle with normal illumination intensity at the moment, so that the fact that the brightness of the tail lamp of the vehicle is adjusted in real time according to whether the vehicle exists at the rear is realized, the influence of dazzling of the rear lamp on a rear vehicle owner due to overhigh brightness of the tail lamp is prevented, meanwhile, the condition that effective driving prompt cannot be carried out on a distant vehicle due to overlow brightness of the tail lamp is prevented, and the safety.
Therefore, according to the control method of the vehicle tail lamp provided by the embodiment of the invention, when the vehicle runs at night, whether other vehicles exist in the preset range behind the vehicle can be detected according to the illumination intensity behind the vehicle, and when other vehicles exist, the illumination intensity of the vehicle tail lamp is automatically adjusted to be proper brightness, so that the dazzling influence on a rear vehicle owner caused by overhigh brightness of the vehicle tail lamp is avoided, the safety of the vehicle and the rear vehicle is improved, and meanwhile, when no other vehicle exists behind the vehicle, the vehicle tail lamp is controlled at normal illumination intensity, so that the effective prompt of a distant vehicle is realized, and the safety of driving at night is ensured.
Further, according to an embodiment of the present invention, the controlling of the tail lights of the vehicle at the preset low light intensity includes: judging the current working state of the tail lamp; if the tail lamp is in the on state at present, adjusting the illumination intensity of the tail lamp to a preset low illumination intensity; if the tail lamp is in a closed state currently, further judging whether a starting signal of the tail lamp is received within preset time, if the starting signal of the tail lamp is received within the preset time, judging whether the illumination intensity is greater than a preset threshold value again, wherein if the illumination intensity is greater than the preset threshold value, the tail lamp is controlled to be started with preset low illumination intensity; and if the illumination intensity is less than or equal to the preset threshold value, controlling the tail lamp to be turned on at the normal illumination intensity.
According to one embodiment of the present invention, a tail lamp of a vehicle is controlled at a normal illumination intensity, including: judging the current working state of the tail lamp; if the tail lamp is in the on state at present, the illumination intensity of the tail lamp is adjusted to the normal illumination intensity; if the tail lamp is in a closed state currently, further judging whether a starting signal of the tail lamp is received within preset time, if the starting signal of the tail lamp is received within the preset time, judging whether the illumination intensity is greater than a preset threshold value again, wherein if the illumination intensity is greater than the preset threshold value, the tail lamp is controlled to be started with preset low illumination intensity; and if the illumination intensity is less than or equal to the preset threshold value, controlling the tail lamp to be turned on at the normal illumination intensity.
Specifically, when the illumination intensity adjusting module judges that the illumination intensity behind the vehicle is greater than the preset threshold value, it indicates that other vehicles are close to the vehicle within the preset range behind the vehicle, and at the moment, the illumination intensity adjusting module can be used for judging the current working state of the tail lamp of the vehicle. When the vehicle tail lamp is currently in the open state, the tail lamp of the vehicle can be controlled according to the preset corresponding information of the illumination intensity adjusting module so as to reduce the illumination intensity of the vehicle tail lamp, the illumination intensity of the tail lamp can be adjusted to the preset low illumination intensity, and therefore the dazzling influence on a vehicle owner of a rear nearer vehicle due to overhigh brightness of the vehicle tail lamp is avoided.
When the vehicle tail light is currently in the off state, whether an on signal of the vehicle tail light is received within a preset time (for example, 5s) can be further judged. If the starting signal of the vehicle tail lamp is received within the preset time, whether the illumination intensity behind the vehicle is larger than the preset threshold value or not is judged again, and when the illumination intensity is larger than the preset threshold value, the vehicle tail lamp is controlled to be started with the preset low illumination intensity, so that the dazzling influence on an owner of a rear nearer vehicle caused by overhigh brightness of the vehicle tail lamp is avoided, and when the illumination intensity is smaller than or equal to the preset threshold value, the tail lamp is controlled to be started with normal illumination intensity, so that the driving prompt of a distant vehicle is effectively carried out, the illumination intensity behind the vehicle is judged again after the starting signal of the vehicle tail lamp is received, the judgment timeliness can be improved, and the control accuracy of the vehicle tail lamp is further improved.
Further, when the illumination intensity adjusting module judges that the illumination intensity behind the vehicle is smaller than or equal to the preset threshold value, it is indicated that no other vehicle approaches the vehicle within the preset range behind the vehicle, and at the moment, the current working state of the tail lamp of the vehicle can be judged through the illumination intensity adjusting module. When the vehicle tail lamp is currently in the opening state, the vehicle tail lamp can be controlled according to corresponding information preset by the illumination intensity adjusting module so as to adjust the illumination intensity of the tail lamp to the normal illumination intensity, and therefore driving prompt is effectively carried out on a remote vehicle.
When the vehicle tail light is currently in the off state, whether an on signal of the vehicle tail light is received within a preset time (for example, 5s) can be further judged. If the starting signal of the vehicle tail lamp is received within the preset time, whether the illumination intensity behind the vehicle is larger than the preset threshold value or not is judged again, and when the illumination intensity is larger than the preset threshold value, the vehicle tail lamp is controlled to be started with the preset low illumination intensity, so that the dazzling influence on an owner of a rear nearer vehicle caused by overhigh brightness of the vehicle tail lamp is avoided, and the vehicle tail lamp is controlled to be started with the normal illumination intensity when the illumination intensity is smaller than or equal to the preset threshold value, so that the driving prompt of a distant vehicle is effectively carried out, the illumination intensity behind the vehicle is judged again after the starting signal of the vehicle tail lamp is received, the judgment timeliness can be improved, and the control accuracy of the vehicle tail lamp is further improved.
That is, in the embodiment of the present invention, in order to effectively identify whether there is another vehicle behind the vehicle, the illumination intensity sensor may be used to detect the illumination intensity behind the vehicle, and then determine whether there is a vehicle behind the vehicle according to the illumination intensity, and adjust the tail lights of the vehicle to have different brightness according to whether there is a vehicle behind the vehicle. When the vehicle tail lamp is adjusted, if the vehicle tail lamp is in an opening state, the illumination intensity of the vehicle tail lamp is adjusted in real time according to the illumination intensity behind the vehicle, for example, when the vehicle approaches, the illumination intensity of the vehicle tail lamp is reduced, and when the vehicle does not approach, the illumination intensity of the vehicle tail lamp is recovered. If the vehicle tail lamp is not turned on, controlling to turn on the vehicle tail lamp with different illumination intensities, and adjusting the illumination intensity of the vehicle tail lamp to different brightness, for example, when the vehicle tail lamp needs to be turned on and other vehicles are behind the current vehicle, controlling to turn on the vehicle tail lamp with low illumination intensity; and when the tail lamp of the vehicle needs to be opened but no other vehicle exists behind the current vehicle, controlling the tail lamp of the vehicle to be opened at normal illumination intensity. Therefore, when the automobile is driven at night, the automobile rear condition can be detected in real time according to the illumination intensity, the illumination intensity of the automobile tail lamp can be adjusted in a self-adaptive mode according to the detected automobile condition, the dazzling influence on an automobile owner at the rear can be prevented, and the driving safety can be improved.
Further, in order to make the present invention more clear to those skilled in the art, the following describes a control method of a tail lamp of a vehicle with reference to a specific example of the present invention. Specifically, as shown in fig. 3a, the control method of the vehicle tail light may include the steps of:

And S407, controlling the tail lamp by the TCM with lower illumination intensity.
And S408, the TCM controls the tail lamp with normal illumination intensity.
