As shown in fig. 1, the application provides an intelligent regulation and control method for a lamp illumination source of a vehicle, the method is applied to an intelligent regulation and control system for the lamp illumination source, an intelligent light control component is integrated in the intelligent regulation and control system for the lamp illumination source, and the intelligent light control component is in communication connection with a laser radar and a vehicle lamplight device, and the method comprises the following steps:
s100: acquiring a first driving plan of a vehicle;
in particular, it should be appreciated that existing vehicle navigation systems may determine a driving route to a destination based on the destination entered by a driving user in conjunction with vehicle current location information.
Based on a specific driving route, the vehicle navigation system can acquire the predicted driving duration and specific road condition information of the driving route by combining big data, wherein the specific road condition information of the driving route comprises, but is not limited to, the number of traffic lights in the whole driving process, the number of bridges and tunnels, the specific positions of speed limiting monitoring points, and the road condition information which is fixed in a short time such as traffic accident frequent road sections, night lighting effects of all road sections and the like.
In this embodiment, the first driving schedule is a driving route of the vehicle from the current position to the destination, and a driving duration and a set of specific road condition information determined based on the driving route.
Optionally, the first driving plan of the vehicle can be determined by acquiring a destination input by the driving user at the beginning of starting the vehicle to determine a driving route through a built-in GPS navigation system of the vehicle or a mobile phone navigation software in communication connection with the vehicle system and then combining big data analysis.
S200: dividing the first driving plan based on time sequence information to obtain a first time sequence driving information set;
in particular, it should be appreciated that during travel of the vehicle, the vehicle travels sequentially through various segments of the planned route to the destination. And the time node sequence of the vehicle running through each road section is the time sequence information.
And dividing the first driving plan based on the time sequence information to obtain road condition information in each driving time sequence. And combining the road condition information in each driving time sequence of the complete driving route to form the first time sequence driving information set.
And combining the time sequence information to form a time sequence segment with larger time span, and correspondingly dividing the first driving plan into road sections with larger distance span. Optionally, the time node of the traffic indicator light of the driving road section is used as a time sequence dividing node, the first route plan is divided to obtain a first time sequence driving information set, and the time sequence equally dividing can be correspondingly divided into the first driving plans.
S300: based on the laser radar, acquiring data of a target range of the vehicle to acquire first monitoring data;
specifically, the laser radar is a vehicle-mounted laser radar arranged on a vehicle, is an 'eye' of the vehicle, can detect and determine whether an obstacle exists in a certain range away from the vehicle, and reduces the visual blind area of a driver. The laser radar reminds a driver of avoiding the obstacle according to the detection result, and traffic safety accidents are avoided.
The minimum value of the target range of the vehicle is a safe vehicle distance, namely, a necessary distance from a front vehicle or a front obstacle in running in order to avoid accidental collision with the front vehicle or the obstacle during running of the vehicle. The target range of the vehicle can be determined according to the current speed, and when the running speed of the vehicle is high, the diameter of the target range of the vehicle corresponding to the data acquisition is prolonged.
The first monitoring data are comprehensive data which are combined with dynamic data around the vehicle collected by the laser radar and the current first time sequence driving information of the vehicle.
The laser radar performs data acquisition within the vehicle target range to obtain dynamic data information with potential safety hazards such as a pedestrian and a pet on the periphery of the vehicle facing an incoming vehicle behind the incoming vehicle, compares the current running time of the vehicle with the first time driving information, determines a specific road section of the current vehicle falling into the first driving plan and the static road condition of the road section, combines the dynamic vehicle periphery information with the dynamic data of the road section on which the current vehicle is located, and obtains the first monitoring data.
S400: determining first external illumination information based on the photosensitive device of the intelligent light control assembly in combination with the first monitoring data;
in particular, it should be understood that the lidar may assist in detecting whether a dynamic obstacle exists in a safe distance around a driving vehicle, but does not have a light sensing capability, so that the present embodiment combines an intelligent light control component to obtain the lighting condition of the dynamic obstacle detected by the lidar, that is, obtain the first external illumination.
In an exemplary manner, during night driving, whether a vehicle is driven in the direction of the vehicle is determined by the laser radar, whether a lamp of the vehicle driven in the direction of the vehicle is a low beam or a high beam is determined by the photosensitive device of the intelligent light control assembly, and the relative illumination intensity.
Through with the lidar with the photosensitive device of intelligent light-operated subassembly is used in combination, reached the accurate in-process of knowing the vehicle and the distance condition of other vehicles and host computer and the relative illumination intensity's of opponent's car lamp to the host computer technical effect.
S500: acquiring an in-vehicle environment light index;
further, as shown in fig. 2, the method step S500 provided by the present application further includes:
s510: acquiring the information of the ambient light in the vehicle through the photosensitive device of the intelligent light control assembly;
s520: determining a brightness index of a lighting device according to illumination information of the lighting device in a vehicle, wherein the brightness index is a first brightness index;
s530: acquiring first screening information by combining the first brightness index through the position information of the photosensitive device and the light device in the vehicle;
S540: and carrying out information screening on the in-vehicle environment light information through the first screening information to determine an in-vehicle environment light index.
Specifically, the in-vehicle light environment index is the in-vehicle light intensity condition perceived by the driver in the cab in the running process of the vehicle, and is the environment light intensity in the space perceived by the driver when the in-vehicle light condition is accurate.
It should be appreciated that during night driving, the interior of the vehicle is ideally in a matt state, and the driver's vision system is balanced with the light outside the vehicle based on the matt state in the vehicle. However, during night driving, the highway lighting system and the lamps of the vehicles coming around the vehicles can cause light rays to exist in the vehicles, and the illumination intensity received by each position in the space in the vehicles is not uniform due to different angles of the incident light.
According to the embodiment, based on the internal structural characteristics of the vehicle, a plurality of photosensitive devices are arranged at different positions in the vehicle and are in communication connection with the intelligent light control assembly, and the acquired environmental light information in the vehicle is transmitted to the vehicle-mounted intelligent light control assembly; determining a brightness index of a lighting device according to illumination information of the lighting device in a vehicle, and defining the brightness index of the lighting device as a first brightness index; acquiring first screening information by combining the first brightness index through the position information of the photosensitive device and the light device in the vehicle; and carrying out information screening on the in-vehicle environment light information based on the first screening information, and determining an in-vehicle environment light index.

For example, for a vehicle with a larger front windshield and a larger side window, the number of photosensitive members needs to be increased at the window edge. And the Sports Utility Vehicle (SUV) has larger volume compared with the common small sedan, and a photosensitive assembly is additionally arranged on the inner frame at the upper limb horizontal line and above of the driver so as to improve the accuracy of acquiring the ambient light in the vehicle.
S600: acquiring a first light control signal through the first external illumination information and the in-vehicle environment light index;
specifically, the first light control signal is a degree signal specifically adjusted to the in-vehicle light device, which is determined by combining the first external illumination information and the in-vehicle environment light index in the driving cab where the driver is located and by comprehensively analyzing the visual photosensitive physiological characteristics of the driver.
For example, when there is light interference outside the current vehicle, which is not collected by the laser radar and the external light sensing device of the intelligent light control assembly, the first light control signal is that no adjustment of the light in the vehicle is needed, so that the light in the vehicle maintains the original illumination intensity or the light in the vehicle maintains the off state. On the contrary, when the external light interference of the current vehicle collected by the external light sensing device of the laser radar and the intelligent light control assembly exists, the first light control signal is used for adjusting and increasing the light intensity of the lamp in the vehicle, so that the illumination intensity of the lamp in the vehicle is increased, and the visual perception system of the driver is ensured to be kept normal.
S700: the first light control signal is combined with time sequence information, and the vehicle light device is controlled through the intelligent light control assembly to intelligently regulate and control the light source of the vehicle.
In particular, it should be understood that ambient light that interferes with the driver's night driving includes the lights of other vehicles and the night lighting conditions of the driving section. Based on the step S100, the first route plan in this embodiment includes the night illumination condition of the whole vehicle driving course, and the specific night illumination condition of the corresponding road section can be obtained based on the time sequence information of the current vehicle driving course.
In this embodiment, the night illumination condition of the road section where the current vehicle is located is obtained based on the time sequence information, the first light control signal is corrected in combination with the road illumination condition, the vehicle light device is controlled based on the corrected first light control signal through the intelligent light control component, and the light illumination source of the vehicle is intelligently regulated and controlled, so that the regulated interior light better balances the influence of external variable light on the visual photosensitive system of the driver in the vehicle.
According to the application, the first driving plan is divided based on the time sequence information to obtain the first time sequence driving information set, so that the matching searching efficiency of matching the vehicle condition dynamic information with the static road condition is improved. Based on the laser radar, acquiring data of a target range of the vehicle to acquire first monitoring data; based on the photosensitive device of the intelligent light control assembly, the first external illumination information is determined by combining the first monitoring data, so that the interference condition of lights of vehicles in other directions around the vehicle on the vehicle under the current vehicle condition is accurately obtained, and accurate interference information is provided for subsequent external light interference elimination. Acquiring a first light control signal through the first external illumination information and the in-vehicle environment light index; the first light control signal is combined with time sequence information, and the vehicle light device is controlled through the intelligent light control assembly to intelligently regulate and control the light source of the vehicle. The interference condition of external environment light on the traffic vision of the driver is accurately obtained, and the interference condition of road fixed illumination on the driver vision is combined, so that the illumination in the vehicle is adjusted to balance the interference of the external light on the balance of the visual system of the driver. The light in the automobile can be timely adjusted according to the change of the light intensity outside the automobile, so that the visual photosensitive system of the driver is always in a state free from the influence of stimulus during driving, the influence of meeting and other strong light conditions on the normal driving of the driver is avoided, and the technical effects of the driving safety coefficient of the automobile and the night driving experience of the user are improved.
Further, the step S200 of the method provided by the present application further includes dividing the first driving plan based on the time sequence information to obtain a first time sequence driving information set:
s210: acquiring time sequence information of the first driving plan;
s220: acquiring time sequence label information based on the time sequence information;
s230: and dividing the first driving plan through time sequence tag information to determine a first time sequence driving information set.
Specifically, the first timing driving information is a road section where the vehicle specifically travels in a certain timing, and specifically includes information such as a road section length of the timing and a road condition in the road section. The first set of timing driving information is a set of first timing driving information for all road segments of the vehicle within a first driving plan.
The time sequence information is the time sequence of each road section node of the vehicle passing through the first driving plan in the process that the vehicle reaches the target position from the current position. And each position of the vehicle on the first driving planned driving route has corresponding time sequence information. Thus the first driving schedule contains a lot of timing information.
The time sequence label information is established to combine a large amount of time sequence information. And dividing the complete route of the first driving plan into a plurality of road sections based on the time sequence label information, wherein the plurality of road sections respectively correspond to one time sequence label, and the first time sequence driving information set is formed by a plurality of driving road sections and a plurality of time sequence labels with corresponding relations.
In this embodiment, the complete route of the first driving plan is divided in the form of time sequence labels, so as to form a plurality of driving road segments and a plurality of time sequence labels corresponding to the driving road segments. And a data base is provided for determining static and dynamic road condition information around the vehicle in the running process of the vehicle by combining the vehicle-mounted radar. Furthermore, the first driving plan is divided according to the time sequence, so that the data density is improved, the difficulty in data processing of the vehicle-mounted system is reduced, and the technical effect of improving the data processing efficiency of the system is achieved.
Further, based on the laser radar, the method step S300 provided by the present application further includes the steps of
S310: based on a laser radar, acquiring data of a target range of a vehicle to acquire first vehicle condition information;
S320: and acquiring a first vehicle condition time sequence tag and first monitoring data through the first vehicle condition information and the first time sequence driving information set, wherein the first monitoring data is synchronous with the first vehicle condition time sequence tag.
Specifically, the first vehicle condition information is object condition information of traffic safety accidents such as oncoming vehicles, oncoming vehicles and pedestrians, which are greater than a threshold value of a safety distance reached by the vehicle in the process of the vehicle traveling according to the first route plan. And the laser radar determines the minimum requirement of the target range of the vehicle for data acquisition according to the running speed of the current vehicle, and performs radar detection based on the target range of the vehicle to acquire the first vehicle condition information greater than a safety running distance critical value.
Determining a specific time sequence label of the first vehicle condition information of the current vehicle running falling into the first time sequence driving information set according to the running time of the current vehicle, giving the specific time sequence label to the first vehicle condition information collected by the laser radar, combining the first vehicle condition information representing the dynamic condition around the current vehicle with the static information of the current road section of the vehicle, and obtaining the first monitoring data of the specific road section condition and the vehicle condition of the first driving plan of the vehicle and the first vehicle condition time sequence label marking the first monitoring data.
According to the method and the device, the dynamic change conditions around the vehicle in the running process of the vehicle are combined with the specific positions of the vehicle on the driving route, so that the technical effects of accurately acquiring the static road section environment conditions of the road section where the vehicle is located and the dynamic change information around the vehicle and accurately acquiring the running safety state of the vehicle are achieved.
Further, the step S600 of obtaining the first light control signal according to the first external illumination information and the in-vehicle environment light index further includes:

s620: inputting the first external illumination information and the in-vehicle environment light index into the light change fitness model to determine a first light source compensation result;
s630: and acquiring a first light control signal through a first light source compensation result.
In particular, it should be understood that the high beam and the low beam of the external illumination of the vehicle are illumination devices which cannot be changed in illumination intensity produced according to the national unified standard, and once the external illumination of the vehicle is changed, visual sensitization of drivers of nearby vehicles can be disturbed, and even the drivers of surrounding vehicles lose control of the driven vehicles due to temporary blindness, so that traffic safety accidents are caused.
Therefore, the embodiment selects to balance the influence of external illumination on safe driving of a driver by adjusting the light in the whole vehicle. In this embodiment, in order to ensure that the light in the vehicle adjusted by the first light control signal satisfies the technical effect of balancing the external light interference stimulus, specific control of the light needs to be determined based on the light source compensation.
The light source of the lamp in the vehicle is correspondingly adjusted, the adjustment is needed according to the accurate first light source compensation result, and the light change adaptability model is a model with multiple logic layers, which can be used for continuously self-training and learning according to different actual conditions, and is simply a mathematical model, and the input layer and the output layer of the model are fixed. Training of the ray change fitness model based on a large number of training data is required, wherein each set of training data comprises: the first external illumination information, the in-vehicle ambient light index and identification information for identifying a first light source compensation result. The neural network model is continuously self-corrected, and when the output information of the neural network model reaches the preset accuracy rate/reaches the convergence state, the supervised learning process is ended. Through the data training of the neural network model to according to training model after training data more accurate characteristic, make the light change fitness model output first light source compensation result also more accurate, and then reached the accuracy and adjusted the illumination intensity of interior lamp light, reached and made the interior light of car can in time carry out accurate regulation according to the change of the outer light intensity of car based on the model, make the driver in the driving period vision sensitization system be in the state of exempting from the stimulation always, improve the technical effect that vehicle driving factor of safety and user were driven at night and experience.

s614: and combining the input layer, the photosensitive functional layer and the output layer to construct a light change adaptability model.
Specifically, the purpose of constructing the light change fitness model in this embodiment is to obtain a more scientific and objective light source compensation result to adjust the brightness of the illumination in the vehicle. The final goal of the illumination adjustment of this embodiment is to serve the driver, so that the specific in-vehicle illumination adjustment needs to be combined with the current light-sensitive physiological condition of the driver of the vehicle. Specifically, acquiring photosensitive function information of a first driving user of the vehicle in combination with a photosensitive function test; taking the photosensitive function information of the first driving user as a reference standard, and taking the historical external illumination information and the historical in-vehicle environment light index as training data to construct a photosensitive function layer; and combining the input layer, the photosensitive functional layer and the output layer to construct a light change adaptability model.

s612-4: and obtaining the photosensitive function information based on the Purkinje phenomenon through the first photosensitive function information and the second photosensitive function information.
In particular, it should be appreciated that the photosensitive function of human vision depends on the functional status of the night vision organ and the day-type organ on the retina. Specifically, the rod body cells are night vision organs, and work under dim lighting conditions to mainly feel the brightness and darkness of an object; pyramidal cells are diurnal organs that function under moderate and intense lighting conditions primarily to perceive the detail and color of an object.
The in-vehicle light index threshold is determined based on in-vehicle natural light and the adjusted in-vehicle illumination intensity, and the light intensity range can be adjusted by the in-vehicle illumination system.
The Purkinje phenomenon is that when people change from cone vision to rod vision, the maximum sensitivity of human eyes to spectrum is moved to a short wave direction, and brightness is changed differently. It is understood that the brightness of the object is perceived as higher than the original brightness when the human is changed from long-period eye closure to eye opening.
The first photosensitive function information and the second photosensitive function information are light intensity ranges which are acceptable and self-regulated by night vision organs and day-type organs on the retina of the current vehicle driver.
Based on the intelligent light control component, simulating a photosensitive function test, and acquiring an in-vehicle environment light index pre-threshold value; determining first photosensitive function information of the rod body cells through the in-vehicle environment light index pre-threshold value; determining second photosensitive function information of cone cells through the in-vehicle environment light index pre-threshold value; and obtaining the photosensitive function information based on the Purkinje phenomenon through the first photosensitive function information and the second photosensitive function information.
According to the embodiment, the light-sensitive physiological characteristics of the vehicle driver are combined with the light adjustment of the vehicle, so that the matching degree of the light adjustment result and the physiological characteristics of the driver is improved, the driving safety coefficient of the driver at night is indirectly improved, and the technical effect that the driver is prevented from being influenced by external light intensity changes to drive normally is achieved.
