For convenience of description, a specific implementation procedure of the lamp control method will be described below by taking a processor in which the implementation subject is a server as an example.
As shown in fig. 2, the vehicle lamp control method applied to the server at least may include:
s202, responding to a car light control signal sent by the vehicle, determining target map data corresponding to the vehicle based on vehicle running information of the vehicle, wherein the vehicle running information at least comprises vehicle speed information and vehicle position information.
Optionally, when the user drives the vehicle in a complex traffic environment, if the vehicle lamp is controlled manually, the safety risk of the user in driving may be increased, and if the vehicle lamp is only irradiated straight, the user may not judge the road condition of the road in front accurately in time when the vehicle turns, and the safety risk is also easy to exist when the vehicle turns. In order to enhance the safety of a user driving the vehicle, the lamp component in the vehicle can sense the environment and carry out adaptive automatic control and adjustment, so that the road condition can be observed more clearly when the user drives, and the driving safety of the user during driving can be further protected through the lamp capable of being regulated and controlled automatically.
Optionally, for automatic adjustment of the vehicle lamp, not only the brightness and the mode of the vehicle lamp need to be automatically adjusted, for example, the high beam mode or the low beam mode needs to be determined according to the opposite incoming condition in the road, but also the vehicle lamp needs to be capable of illuminating the road to be turned in front in time when the vehicle turns, so that the driving safety of the user is protected, namely, the vehicle lamp needs to be capable of adjusting the irradiation angle of the vehicle lamp according to the bending degree of the road turned in front, so that the user can observe the road condition more clearly when turning. When the automatic control of the vehicle lamp is carried out, the driving environment of the vehicle is firstly perceived, deflection data corresponding to the vehicle lamp is calculated according to the driving environment of the vehicle, then the vehicle lamp is regulated according to the deflection data, and the light direction is kept consistent with the current running direction of the vehicle, so that the optimal illumination is provided for the road in front. However, in order to implement calculation of lamp deflection control, it is necessary to install hardware devices dedicated to various lamp automatic control function modules such as a sensor module, an electronic control unit (lamp adjustment control unit), an actuator (lamp dynamic adjustment motor) and the like in the vehicle, and therefore, if calculation of lamp control data is performed in the vehicle, the cost of software and hardware of the vehicle increases.
Optionally, in order to reduce the software and hardware cost of the vehicle end, reduce the calculation pressure of the vehicle end, deflection data of the vehicle lamp can be calculated in a vehicle networking cloud platform (Telematics Service Platform, TSP) connected with the vehicle, the vehicle networking cloud platform is used for realizing various function services of the vehicle networking, can communicate with the vehicle, and carries out mutual message data receiving and sending with the vehicle, and the like, generally, the calculation force of the vehicle networking cloud platform is higher, more reliable and stable, the vehicle networking cloud platform can realize real-time expansion, the optimization and updating of the vehicle lamp control service are convenient, the vehicle lamp control service is provided for the vehicle through the vehicle networking cloud platform, the calculation force requirement on the vehicle end can be reduced, the cost of the vehicle is reduced, and the vehicle using experience of a user is improved.
Optionally, to calculate deflection data of the vehicle lamp through the internet of vehicles cloud platform, the vehicle is required to send a generated vehicle lamp control signal to a server where the internet of vehicles cloud platform is located when the vehicle has the automatic control requirement of the vehicle lamp, at this time, the server responds to the vehicle lamp control signal sent by the vehicle to calculate the deflection data of the vehicle lamp, the deflection data comprises a deflection angle and a deflection direction, and then the deflection data is sent to the vehicle to enable the vehicle to regulate the vehicle lamp according to the deflection data, so that the calculation of the vehicle lamp control is migrated to the server, and the calculation cost of a vehicle end can be reduced.
Further, in order to perform adaptive control of the vehicle lamp under different environments, the vehicle needs to adjust the vehicle lamp to a mode capable of receiving autonomous control of the vehicle, namely an automatic vehicle lamp mode, then in order to adjust the vehicle lamp according to the environments, a change of driving environments needs to be monitored through photosensitive sensors around a vehicle body, when light conditions of the surrounding environments are monitored to prevent a user from accurately observing road conditions, automatic opening of the vehicle lamp can be achieved, and when the light conditions of the surrounding environments are monitored to be enough for the user to observe clear road conditions, automatic closing of the vehicle lamp can be achieved. In this application embodiment, set up and predetermine light environment for can hinder the environment of user's observation road conditions, then in driving the in-process, when the vehicle is in automatic car light mode and when predetermine light environment is detected through photosensitive sensor, the car light can be automatic start, if the demand of car light is deflected in the vehicle production this moment, just directly produces car light control signal to send car light control signal to the server, so that the server carries out the calculation of car light deflection data.
Optionally, in the driving process of the vehicle, a continuous communication network connection exists between the vehicle and a server where the internet of vehicles cloud platform is located, so that information data transmission between the vehicle and the server is facilitated. In particular, the server and the vehicle communicate via a mobile communication network, and available mobile communication networks include multiple generations, such as a third generation mobile communication network (3 generation, 3G), a fourth generation mobile communication network (4 generation, 4G), and a fifth generation mobile communication network (5 generation, 5G), where the speed of the 5G network is the fastest, so in a preferred embodiment, the vehicle and the server communicate based on the fifth generation mobile communication network, i.e., the 5G network.
Further, when using a 5G network, the vehicle communicates with the server specifically through a 5G core (5G core,5G C), which is the core part of the 5G mobile communication system, responsible for handling the communication between the mobile device and the internet. In the 5G era, the mobile network service is no longer a mere mobile phone, but various types of devices, such as mobile phones, tablets, fixed sensors, vehicles, etc., and the application scenarios are diversified, such as mobile broadband, large-scale internet, mission critical internet, etc., and the requirements to be satisfied are diversified, such as mobility, security, time delay, reliability, etc. At this time, the network slicing technology is generated, and a plurality of virtual logic networks are sliced on an independent physical network through the network slicing technology, so that a special physical network is prevented from being built for each service, and the effect of saving cost is achieved. Generally, a 5G network divides network slices according to different demands of different groups, for example, when a large number of services in a server need to be supported to connect with vehicles, a large number of connection slices divided in the 5G network can be used; when the delay of data transmission needs to be reduced, a low-delay network slice divided in a 5G network can be used; when it is desired to boost the amount of data transferred at a time, a high bandwidth network slice divided in the 5G network may be used. In this embodiment, the 5G network is cut into a plurality of virtual and isolated independent virtual networks, different network slices have different data transmission characteristics, and different information transmission services are respectively handled, and data transmission is performed through at least one network slice in the mobile communication network during each communication process between the server and the vehicle, where in a preferred embodiment, when the vehicle sends a control signal for the vehicle lamp to the server, the control signal may be implemented through a mass connection slice in the 5G network.
Optionally, the server receives the lamp control signal sent by the vehicle through the mass connection slice, when responding to the lamp control signal, it needs to determine the deflection operation that the lamp should perform according to the road condition and the running state in the actual environment where the vehicle is located, so as to keep the light direction consistent with the current running direction of the vehicle, so as to ensure that the best illumination is provided for the road ahead, that is, the server firstly positions the vehicle based on the vehicle speed information of the vehicle and the vehicle running information such as the vehicle position information, so as to determine the target map data corresponding to the vehicle, and is convenient to determine the road condition when the vehicle runs according to the map information of the area where the vehicle is located.
S204, calculating deflection data of the car lamp according to the target map data and the car running information, wherein the deflection data comprises a deflection angle and a deflection direction.
Alternatively, after the server determines the target map data of the position where the vehicle is located, in combination with the vehicle running information, it is possible to calculate whether there is a steering road on the road where the vehicle is running next and when the vehicle will run to the steering place, and the like, and based on analysis of these vehicle running states, it is possible to calculate the yaw angle and yaw direction at which the vehicle lamp can coincide with the running direction of the vehicle.
Specifically, when the vehicle is traveling on a multi-lane road, lanes with different traveling directions such as a straight lane, a left-turn lane, a turning lane, and the like may exist on the road ahead at the same time, and at this time, it is necessary to accurately determine the traveling intention of the user, so as to pre-determine the upcoming steering behavior of the user, and calculate the lamp deflection data corresponding to the traveling direction that accords with the traveling intention of the user in time. Considering that the control information of the steering wheel of the user often reflects the control requirement of the user on the vehicle when the user drives the vehicle, for example, when the user needs to turn left, the steering wheel is often controlled to deflect in advance before entering a curve so as to realize smooth steering of the vehicle, based on the control information, when the steering wheel control information is included in the vehicle driving information, whether the vehicle has steering intention or not can be analyzed through the steering wheel control information, when the steering intention exists, the bending information of a road to be steered in front of the vehicle is determined according to the target map data, and finally the deflection data of the vehicle lamp is calculated based on the vehicle driving information and the bending information.
S206, transmitting the deflection data to the vehicle so that the vehicle adjusts the vehicle lamp according to the deflection data.
Optionally, after calculating the angle at which the lamp should deflect, the server sends deflection data to the vehicle to cause the vehicle to adjust the lamp in accordance with the deflection data. Specifically, the deflection data may be in the form of being carried in a lamp control command, which is sent by the server to the vehicle, so that the vehicle adjusts the lamp according to the deflection data in the lamp control command. Wherein, the deflection data comprises a deflection angle and a deflection direction, and then the vehicle can adjust the irradiation angle of the car lamp according to the deflection angle and adjust the irradiation direction of the car lamp according to the deflection direction.
