Referring to fig. 2, an embodiment of the present invention provides a vehicle high beam control method, including:
step S10, when the current driving road section of the vehicle is a high-speed road section, judging whether the current ambient illuminance is less than a preset illuminance threshold value and whether an unsuppressed condition is satisfied simultaneously;
the method for judging whether the current road section is the high-speed road section is based on a vehicle-mounted navigation system, the vehicle-mounted navigation system can judge the road type of the current running road section of the vehicle according to a loaded road map, the road types are mainly divided into two categories of the high-speed road section and the non-high-speed road section, and the vehicle-mounted navigation system can directly extract the road type of the road section based on the road section where the vehicle is located, so that whether the current running road section of the vehicle is the high-speed road section or the non-high-speed road section is determined.
To assist in understanding the technical solutions of the present application, the following terms are explained:
the ambient light illumination is the amount of the illumination degree of the surface area of the object reflected by the intensity of the ambient light, and the stronger the ambient light illumination is, the wider the surface area of the object to be illuminated is; the weaker the ambient light level, the smaller the surface area of the object illuminated.
The preset illumination threshold is obtained by observing the picture under different ambient illumination, and when the picture is observed to tend to be blurred, the corresponding numerical value is the preset illumination threshold. When the ambient illuminance is greater than the preset illuminance threshold, the ambient illuminance is sufficient at the moment, and the high beam lamp does not need to be started; when the ambient illuminance is less than the preset illuminance threshold, it indicates that the ambient illuminance is insufficient at this time, and the high beam lamp needs to be turned on to supplement the illuminance.
The suppression condition refers to an operation of active intervention by the driver, such as the driver actively turning on a high beam or a low beam.
And only when the current ambient illuminance is detected to be smaller than the preset illuminance threshold value and the no-inhibition condition is simultaneously established, the next judgment condition is carried out, so that the waste of vehicle performance resources is avoided.
Step S20, if yes, judging whether the vehicle has the same-direction front vehicle or the opposite-direction vehicle;
when the ambient illuminance is smaller than the preset illuminance threshold and the no-inhibition condition is simultaneously established, the situation that the vehicle is currently running on a high-speed road section, the road light is dim and the driver does not turn on the high beam is indicated, the running road section at the moment has traffic safety hazards, and traffic safety accidents can be avoided only by turning on the high beam of the vehicle.
Whether the same-direction front vehicle or the opposite-direction coming vehicle exists or not can be judged based on the vehicle-mounted radar of the vehicle, because the shooting performance of the camera is limited under the condition of dim road light, whether the front vehicle exists or not cannot be accurately judged, or the number of the driving distance between the front vehicle and the vehicle cannot be confirmed when the front vehicle exists, so that the driving safety of a user is improved, the vehicle-mounted radar is automatically started to acquire the information of the front driving vehicle when the dim road light is detected, and the safety of the user is guaranteed.
Because the vehicle-mounted radar can monitor the road traffic condition in front of the automobile and the data of the front vehicle, and the vehicle-mounted radar can also distinguish the position, the direction, the distance and the speed of the movement of the vehicle, the vehicle can distinguish whether the front vehicle is the same-direction vehicle or the opposite-direction vehicle based on the function of the vehicle-mounted radar.
Optionally, after the step of determining whether there is a preceding vehicle or an oncoming vehicle, the method further includes:
if the vehicle does not have the same-direction front vehicle or the opposite-direction coming vehicle, the high beam of the vehicle is turned on.
If the vehicles in the same direction or the vehicles coming from opposite directions do not exist, the situation that other drivers are not affected by the turning-on of the high beam at the moment is explained, so that the turning-on of the high beam can enable the drivers to see the road situation in front clearly, the speed of the vehicles can be adjusted in time, and the driving safety is guaranteed.
Step S30, if there is an oncoming vehicle, directly turning on the vehicle high beam of the vehicle;
because the anti-glare belt is arranged on the high-speed road section and can effectively weaken the strong light interference of the high-beam light to the oncoming vehicles, even if the oncoming vehicles exist in front of the vehicle, the driver of the oncoming vehicles cannot be dazzled by turning on the high-beam light of the vehicle, and the driving vision can be better provided for the driver of the vehicle.
Step S40, if the same-direction vehicle exists, judging whether the driving distance between the vehicle and the same-direction vehicle is larger than the preset driving distance value;
the driving distance is the result that can be directly extracted according to the data of the vehicle-mounted radar.
The driving distance preset value is based on the range which can be irradiated by setting different distances for the vehicle and combining the high beam and the dipped headlight, the driver of the vehicle can observe the size of the visual range based on different distances for many times, when a certain distance value is reached, the driver can observe the front vehicle only by starting the high beam, and the driver cannot dazzle the front vehicle when starting the high beam at the distance value, the distance value is the minimum visual safety distance between the vehicle and the front vehicle, namely the driving distance preset value, and the distance and the range which can be irradiated by the high beam and the dipped headlight are different. For example, the distance and range that the high beam can irradiate are 2 units, and the distance and range that the low beam can irradiate are 1 unit, so when the distance between the traveling vehicles is greater than 1 unit, the high beam must be turned on to provide a wider field of view, and the 1 unit is located at the preset value of the distance between the traveling vehicles.
Optionally, after the step of determining whether the driving distance between the vehicle and the vehicle in the same direction is greater than the preset driving distance value, the method further includes:
and if the driving distance between the vehicle in the same direction and the vehicle is smaller than or equal to the preset driving distance, closing the vehicle high beam of the vehicle.
When the driving distance is smaller than or equal to the preset driving distance value, the situation that the light of the high beam can cause transient glaring to the driver of the same-direction front vehicle is shown, and the situation that the transient glaring to the driver of the same-direction front vehicle can be avoided only by timely switching to the low beam is required, so that traffic accidents are avoided.
And step S50, if the distance between the vehicles is larger than the preset distance, the high beam of the vehicle is turned on.
When the distance between the vehicles is larger than the preset distance, the distance between the vehicles is larger than the minimum visual safe distance, so that the turning-on of the high beam of the vehicle cannot cause transient glaring to the drivers of the vehicles ahead in the same direction, and clear front road vision can be provided for the drivers of the vehicles.
Optionally, after the step of determining that the distance between the vehicles is greater than the preset distance, the method further includes:
and counting the duration of the driving distance which is continuously greater than or equal to the preset driving distance value, and judging whether the duration is greater than or equal to the preset time value.
The duration of the preset distance is directly obtained according to the vehicle-mounted radar.
The time preset value is based on setting different vehicle speed sections for the vehicle, wherein the different vehicle speed sections correspond to different time preset values, and the faster the vehicle speed is, the longer the time required for stabilizing the vehicle distance is; the slower the vehicle speed is, the shorter the time required for stabilizing the vehicle distance is, the whole value in each vehicle speed section is taken as the vehicle speed experimental value of the vehicle, the total stabilization time required for the vehicle speed experimental value of each vehicle speed section is divided by the total number of the vehicle speed experimental values of each vehicle speed section, the calculated value is the required time length for stabilizing the vehicle distance of each vehicle speed section of the vehicle, namely the time preset value, for example, three groups of different vehicle speed sections of 60-80, 80-100 and 100-plus 120 are respectively set, the three groups of vehicle speed sections are rounded to obtain 3 vehicle speed experimental values of each group, the vehicle distance stabilization time required for the 3 vehicle speed experimental values of the first group is a seconds, and the vehicle distance stabilization time required for the 3 vehicle speed experimental values of the second group is b seconds. And the third group is c seconds, the time preset values corresponding to the three groups of vehicle speed sections are a × 3/3 seconds, b × 3/3 seconds and c × 3/3 seconds respectively, the time preset values can avoid the situation that the high beam switch state is switched continuously when the distance between the traveling vehicles changes frequently between 1 unit and 1.1 unit, the time preset value s2 is set, the distance between the traveling vehicles can be changed from 1 unit to 1.1 unit, the high beam can be switched on when the duration kept by 1.1 unit is greater than s2, and the high beam is not switched on when the duration kept by 1.1 unit is less than s 2.
Only when the duration of the driving distance triggers the preset value of the driving distance, the duration of the driving distance is counted, and unnecessary resource waste is avoided.
And if the duration is greater than or equal to the preset time value, changing the state of the high beam of the current vehicle.
If the duration is greater than or equal to the preset time value, the driving distance of the vehicle is a stable value at the moment, the state of the current high beam of the vehicle is changed, and if the high beam of the vehicle is in an open state, the high beam of the vehicle is changed into a closed state; if the vehicle far-off lamp is in the off state at the moment, the vehicle far-off lamp is changed into the on state.
And if the duration is less than the preset time value, the state of the high beam of the current vehicle is not changed, and the step of counting the duration of the distance between the vehicles continuously greater than the preset distance between the vehicles is executed.
If the duration is less than the preset time value, the driving distance of the vehicle is not a stable value, in order to avoid frequent switching of the high beam, the high beam of the vehicle is judged to be in a non-switching state, the counted duration is cleared, and the counting of the duration of the driving distance is restarted.
In the embodiment, the starting condition of the intelligent high beam on the expressway is realized by combining a vehicle-mounted navigation system, and the on-off state of the high beam of the vehicle can be automatically adjusted by a vehicle high beam control system according to the front information reflected by the radar through the front information monitored by the radar in the driving process, including the driving direction of the vehicle and the distance between the vehicles in the same direction, so that the optimization of the starting condition of the intelligent high beam is realized, and the defect that the light source is automatically switched to the dipped headlight once a camera detects the light source is avoided, thereby causing the problem that the front view of a driver is limited; when the distance between the vehicle and the front vehicle is too close, the high beam of the vehicle cannot be timely switched into the dipped headlight, so that the driver of the front vehicle dazzles the traffic safety hidden trouble caused, the performance of the high beam of the vehicle is improved, the driving risk on the highway at night is reduced, and the driving safety of drivers is guaranteed.

the early-stage judgment conditions of the non-high-speed road section and the high-speed road section are the same, when the ambient light intensity is smaller than the preset light intensity threshold value and the no-inhibition condition is simultaneously established, the next judgment condition is carried out, the next judgment operation is distinguished from the judgment condition of the high-speed road section, the non-high-speed road section only needs to judge whether a vehicle runs ahead or not, and the high-speed road section only needs to judge whether the vehicle runs ahead or not, and when the vehicle runs ahead, the direction of the vehicle running ahead is the same as that of the vehicle running ahead or the vehicle running ahead needs to be judged. Since the road types of the highway section and the non-highway section are different, the judgment conditions for turning on the high beam of the vehicle are different.
Step S03, if the two conditions are satisfied, judging whether the running vehicle exists in front of the vehicle;
referring to fig. 4, the different judgment conditions for turning on the high beam of the vehicle on the highway section and the non-highway section are that the anti-glare belt is arranged on the highway section, so that traffic safety accidents caused by the fact that the high beam dazzles the eyes of drivers in front can be prevented, and the condition for turning on the high beam on the highway section does not need to consider the condition of oncoming vehicles but only the condition of oncoming vehicles.
And the non-high-speed road section is not provided with the anti-glare belt, if a running vehicle exists in front of the vehicle, no matter the running vehicle in front is a forward vehicle in the same direction or an opposite vehicle, the opening of the high beam can cause glare to a driver of the running vehicle in front, so that the driver has short blurred vision, the driver cannot accurately judge the distance between the vehicles and adjust the speed of the vehicle in time, and great potential safety hazards exist. Therefore, whether the high beam of the vehicle on the non-high-speed road section is started or not is judged, whether the ambient illuminance is smaller than a preset illuminance threshold value or not and whether the inhibition condition exists or not are judged, whether a running vehicle exists in front of the vehicle is judged, and the high beam of the vehicle is started only when no running vehicle exists or the running vehicle exists and the running vehicle distance is larger than the running vehicle distance preset value.

Therefore, the vehicle-mounted radar can monitor the traffic condition of the road in front of the automobile and the data of the vehicle in front of the automobile, the vehicle-mounted radar can distinguish the position, the direction, the distance and the speed of the movement of the vehicle, and under the conditions that the ambient light intensity is insufficient and the performance of the camera is limited, the vehicle-mounted radar can accurately distinguish the traffic condition and the vehicle data of the road in front of the automobile, so that the driving safety of a user is guaranteed.
Optionally, after the step of dynamically acquiring whether there is a running vehicle in front of the vehicle based on the vehicle-mounted radar of the vehicle, the method further includes:
step A1, if a driving vehicle is in front of the vehicle and the driving distance between the front driving vehicle and the vehicle is smaller than or equal to the preset driving distance value, turning off the high beam of the vehicle;
in step a2, if there is no traveling vehicle in front of the vehicle, the high beam of the vehicle is turned on.
If no driving vehicle exists in the front, the situation that the front driver is not influenced by turning on the high beam at the moment is explained, so that the turning on of the high beam can enable the driver to clearly see the road situation in the front, the speed of the vehicle can be adjusted in time, and the driving safety is further guaranteed.
