As shown in fig. 2, the light control system 10 of the vehicle is applied to a server, and the system 10 includes: a sensor assembly 100, a road detection assembly 200, and a light controller 300.
Specifically, the sensor assembly 100 is used for collecting pressure data, vibration data, sound data and/or infrared data of a current road.
It can be appreciated that in the embodiment of the present application, the sensor assembly 100 may collect pressure data, vibration data, sound data and infrared data of the road in real time, and convert analog signals into digital signals through the converter, so that the microprocessor processes and stores the digital signals, thereby comprehensively knowing the condition of the road and meeting different road monitoring requirements.

The road detection component 200 is used for detecting the obstacle information of the current road according to the pressure data, the vibration data, the sound data and/or the infrared data.
It may be appreciated that in the embodiment of the present application, the vehicle may acquire the road data of the driving road based on the cloud server, and perform preprocessing including filtering, denoising, signal enhancement and other processes on the received road data by the road detection component 200, so as to improve the data quality and accuracy, and detect the obstacle information of the current road according to and according to the pressure data, the vibration data, the sound data and/or the infrared data in the road data, so as to more fully understand the road condition.

In some embodiments, the appropriate features may be extracted from different types of data to represent the obstacle information. For example, the maximum pressure value or pressure change rate may be extracted for pressure data, the vibration frequency or amplitude may be extracted for vibration data, the sound intensity or spectral characteristics may be extracted for sound data, and the distance or temperature of the object may be extracted for infrared data. Further, based on the result of the feature extraction, obstacle detection is performed by an appropriate algorithm, such as a machine learning algorithm, a signal processing algorithm, and a pattern recognition algorithm. When it is detected that an obstacle exists, the positioning unit may acquire relative position information of the vehicle and the obstacle using a position sensor (such as a GPS) on the vehicle and an obstacle position sensor (such as a laser radar or a camera), calculate parameters such as a distance, a direction, a relative speed, etc. between the obstacle and the vehicle, and information such as coordinates, a size, a type, a movement state, etc. of a relative position of the obstacle and the vehicle, obtain the relative position information of the obstacle and the vehicle, and generate the obstacle information based on the relative position information and the obstacle.
The light controller 300 is configured to confirm an actual driving scene of the vehicle according to the obstacle information, and generate a target light type and a target light duration of the vehicle based on the actual driving scene and the obstacle information, so as to control a light component of the vehicle to work according to the target light type and the target light duration.
It is understood that in the embodiment of the present application, the light controller 300 may perform confirmation of an actual driving scenario based on the obstacle information and the vehicle state data. For example, it is determined whether there is a forward obstacle, road condition (e.g., curve, gradient, etc.), and vehicle running state (e.g., acceleration, deceleration, etc.). The light controller 300 generates the target light type and the target light duration of the vehicle according to the confirmed driving scene and the obstacle information, and transmits the generated target light type and target light duration to the light component of the vehicle so as to flexibly adjust the target light type and duration according to the changes of different driving scenes and the obstacle information and meet the requirements of different driving situations.
Specifically, as shown in fig. 3, after confirming that the actual driving scene of the vehicle is the intersection driving scene according to the obstacle information, the light controller 300 controls the headlight of the current vehicle in the high beam state to be switched to the low beam, so as to avoid dazzling of the current vehicle to the waiting vehicle driver, the driving vehicle driver, the pedestrians and other people in the target area.
Optionally, in one embodiment of the present application, the light controller 300 further includes: an extraction unit for extracting at least one current road feature according to the obstacle information; and the identification unit is used for determining the actual driving scene of the vehicle according to at least one current road characteristic.
In the actual execution process, at least one current road feature can be obtained by extracting the acquired obstacle information through methods such as signal processing, image processing, pattern recognition and the like, for example, the distance, the size, the type and the like of the obstacle can be extracted, the actual driving scene of the vehicle is determined by utilizing a preset algorithm model according to the extracted current road feature, for example, the driving scene is recognized according to the characteristics such as the distance, the size, the type, the speed and the driving direction of the obstacle, for example, the crossroad scene, the meeting scene, the expressway scene and the like.
Optionally, in one embodiment of the present application, the light controller 300 includes: the matching unit is used for matching the target lamplight type according to the actual driving scene and generating target lamplight duration based on the relative position information of the obstacle and the vehicle; and the switching unit is used for controlling the vehicle lamplight to be switched into the target lamplight type when the target lamplight time length is larger than a preset threshold value.
It should be noted that the preset threshold may be set by a person skilled in the art according to the actual situation, and is not specifically limited herein.
In the embodiment of the application, the target light type can be matched with the current driving scene according to the actual driving scene. For example, the type of target light that should be used, such as high beam lights, low beam lights, warning lights, fog lights, etc., and the corresponding light orientation, are determined according to the characteristics of the driving scene. And further, generating a target light duration based on the matched target light type according to the relative position information of the obstacle and the vehicle, for example, calculating the duration required by the target light according to the distance, the speed and other parameters of the obstacle and the vehicle, and when the target light duration is greater than a preset threshold value, switching the light component for controlling the vehicle into the target light type generated by the matching unit by the switching unit, and continuously operating the corresponding target light duration.
For example, as shown in fig. 4, after confirming that the actual driving scene of the vehicle is the co-directional road driving and following driving scene according to the obstacle information, the vehicle information passing through the forward co-directional vehicle driving path, that is, the obstacle information, can predict the speed difference between the current vehicle and the vehicle approaching ahead and switch the light setting in advance according to the distance change, so as to avoid dazzling the driver ahead.
For example, as shown in fig. 5, after confirming that the actual driving scene of the vehicle is the driving scene of meeting the vehicle on the road according to the obstacle information, the light setting can be switched in advance according to the vehicle information passing on the driving path of the front opposite vehicle, i.e. the obstacle information, so as to predict the distance change between the current vehicle and the vehicle coming ahead in advance, thereby avoiding the dazzling situation of the front driver.
According to the light control system of the vehicle, which is provided by the embodiment of the application, the obstacle information of the current road and the actual driving scene of the vehicle can be obtained based on the pressure data, the vibration data, the sound data and/or the infrared data of the current road, so that the type and the light duration of the required vehicle light are confirmed, accurate and efficient vehicle light switching is realized, and the accuracy and the reliability of vehicle light control are improved.
