The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The vehicle lamp control method provided by the embodiment can be applied to the application environment shown in fig. 1. The vehicle lamp control terminal 102 and the server 104 communicate with each other through a network. The vehicle light control terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server 104 may be implemented as a stand-alone server or as a server cluster comprised of multiple servers.
It should be noted that, in the vehicle lamp control method provided in the embodiment of the present application, the execution main body may be a vehicle lamp control device, and the device may be implemented as part or all of a vehicle lamp control terminal by software, hardware, or a combination of software and hardware.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
Fig. 2 is a schematic flow chart of a vehicle lamp control method according to an embodiment. The present embodiment relates to a specific process of how to control the on state of the vehicle lamp. As shown in fig. 2, the method comprises the steps of:
s101, obtaining a relative motion track of the networked object relative to the vehicle in a target time period; the target period is a period of time after the current time.
Specifically, the networked objects may be other traffic objects running on a road, and are connected to the server through a network, where the networked objects may be pedestrians, bicycles, and motor vehicles, and the embodiments of the present application do not limit this. The networked object may be one object or a plurality of objects, which is not limited in this embodiment of the application. When the server is connected to the network through the network, the server may be connected to the network through a communication device provided on the networked object, or the driver of the networked object may be connected to the server through an application program on the terminal device, which is not limited in the embodiment of the present application. The target time period may refer to a time period after the current time, and may be a time period taking the current time as a start, or a time period taking a time after the current time as a start, which is not limited in the embodiment of the present application. The relative motion trajectory may refer to a motion trajectory of an intranet object relative to a vehicle during a target period, where both the networking object and the vehicle may be in a moving state. Since the target period is a period of time after the current time, the relative movement locus is a predicted movement locus of the intranet object relative to the vehicle in the target period. The networked object may be one object or a plurality of objects, and accordingly, the relative motion trajectory may be one motion trajectory of one object relative to the vehicle in the target time period, or a plurality of motion trajectories of a plurality of objects relative to the vehicle in the target time period. If the relative movement trajectory is a dynamic positional relationship between the networked object and the vehicle, it can be determined whether the networked object is traveling toward the vehicle based on the relative movement trajectory. For example, within the target time period, as time progresses, the distance between the networked object and the vehicle gets closer and closer at a rate greater than a preset threshold, then the networked object travels toward the vehicle.
In the process of specifically obtaining the relative motion trajectory of the networked object to the vehicle in the target time period, the relative motion trajectory may be obtained through the motion trajectory of the networked object in the target time period and the motion trajectory of the vehicle in the target time period, or the motion direction of the networked object in the target time period may be predicted through the historical motion trajectory of the networked object, so as to obtain the predicted motion trajectory of the networked object, and the relative motion trajectory may be predicted according to the motion trajectory of the vehicle itself, which is not limited in the embodiment of the present application.
And S102, controlling the lamp starting state of the vehicle according to the relative motion track and the target area in front of the vehicle.
Specifically, the target area in front of the vehicle may be an area irradiated by the vehicle high beam, or an area obtained by enlarging the irradiation range of the vehicle high beam according to a preset expansion threshold, which is not limited in the embodiment of the present application. The vehicle lamp of the vehicle includes at least one of a high beam lamp and a low beam lamp, which may be a halogen lamp, a xenon lamp, or a matrix lamp, and the embodiment of the present application is not limited thereto. The starting state of the car light can comprise a starting state and a closing state, and in a scene, when the car light is a matrix light, the starting state of the car light further comprises the number of the lights in the matrix light array, and the embodiment of the application does not limit the number of the lights.
On the basis of the embodiment, when the relative motion track of the networked object relative to the vehicle in the target time period is obtained, the terminal can judge whether the driving direction of the networked object faces towards the vehicle or deviates from the vehicle according to the relative motion track, and simultaneously, the time when the networked object enters the target area in front of the vehicle is determined according to the relative motion track, so that the vehicle lamp of the vehicle is switched from the high beam mode to the low beam mode before the time when the networked object enters the high beam irradiation range of the vehicle. For example, when the target area is the irradiation range of the high beam light in front of the vehicle, when the networked object is obtained to be driven towards the vehicle according to the relative motion track, and the position information of the networked object relative to the vehicle at each time in the target time period is obtained according to the relative motion track, so that the networked object enters the target area at the time T, the vehicle light of the vehicle can be controlled, and the high beam light mode of the vehicle light is switched to the low beam light mode 2 seconds before the time T. When the target area is an area obtained by enlarging the irradiation range of the high beam of the vehicle according to a preset enlarging threshold, when the networking object is obtained according to the relative motion track and is driven towards the vehicle, and the position information of each moment relative to the vehicle in the target time period of the networking object is obtained according to the relative motion track, so that the networking object is obtained to enter the target area at the time T, the lamp of the vehicle can be controlled, and the lamp is switched from the high beam mode to the dipped beam mode at the time T. When the turning-on state of the vehicle lamp is specifically controlled, the turning-on state of the vehicle lamp CAN be controlled in a mode of transmitting a control signal through a Controller Area Network (CAN), or through a FlexRay signal.
In the vehicle lamp control method, the terminal obtains the relative motion track of the networked object relative to the vehicle in the target time period, wherein the target time interval is a time interval after the current time, and further controls the starting state of the vehicle lamp according to the relative motion track and the target area in front of the vehicle, in the application, the terminal controls the starting state of the vehicle lamp according to the relative motion track of the networked object relative to the vehicle and the target area in front of the vehicle in the target time interval, the starting state of the vehicle lamp is determined according to the relative motion track of the intranet object relative to the vehicle and the target area in front of the vehicle in the time period after the current moment, the condition that whether the high beam needs to be closed or not is judged after the traffic object running oppositely enters the high beam irradiation area is avoided, and then avoided the untimely problem of closing of high beam, improved the security that the vehicle travel.
Fig. 3 is a flow chart illustrating a vehicle lamp control method according to another embodiment. The present embodiment relates to a specific process of how to control the on state of the lamp of the vehicle according to the relative movement locus and the target area in front of the vehicle. As shown in fig. 3, one possible implementation method of the above S102 "controlling the lamp-on state of the vehicle according to the relative motion trajectory and the target area in front of the vehicle" includes the following steps:
s201, judging whether a target motion track exists or not according to the relative motion track and a target area in front of the vehicle; the target motion trajectory is a relative motion trajectory that is directed toward the vehicle and falls into the target area, and if yes, S202 is performed.
In particular, the target motion trajectory may be a relative motion trajectory of the networked objects directed towards the vehicle and falling into the target area. On the basis of the foregoing embodiment, the networked object may be one object or multiple objects, and accordingly, the target motion trajectory may be one motion trajectory or multiple motion trajectories, which is not limited in this embodiment of the present application. Further, on the basis of the above-described embodiment, when the relative motion trajectory is obtained, it may be determined whether the networked object in the relative motion trajectory travels toward the vehicle within the target period and enters the target area in front of the vehicle at a time within the target period to determine whether the target motion trajectory exists. For example, if there is a networked object in the relative motion trajectory that travels toward the vehicle within the target time period and enters a target area in front of the vehicle at a certain time within the target time period, there is a target motion trajectory; if all the networking objects in the relative motion trail deviate from the vehicle to run in the target time period, and meanwhile, the networking objects are in a target area in front of the vehicle in the target time period, or the networking objects are not in the target area in front of the vehicle in the target time period, the target motion trail does not exist; if each networked object in the relative motion trajectory travels toward the vehicle within the target time period and does not enter the target area in front of the vehicle within the target time period, the target motion trajectory does not exist.
And S202, controlling the vehicle to be switched from the high beam mode to the low beam mode.
Specifically, the high beam mode may refer to a mode in which the high beam is turned on by the vehicle, and at this time, the low beam of the vehicle may be turned on or off. The low beam mode may refer to a mode in which the vehicle turns on the low beam while the high beam of the vehicle is off. On the basis of the above embodiment, if it is determined that the target motion trajectory exists, the vehicle may be controlled to switch from the high beam mode to the low beam mode. The terminal can control the vehicle to be switched from the high beam mode to the low beam mode immediately when determining that the target motion trail exists, can switch the vehicle from the high beam mode to the low beam mode at intervals of preset time intervals, can also determine the moment when the networked vehicle enters the target area according to the target motion trail, and switches the vehicle from the high beam mode to the low beam mode at the moment.
On the basis of the above embodiment, after the networked object leaves the target area, the headlights can also be automatically switched from the low beam mode back to the high beam mode. Alternatively, when it is determined that there is no networking object that is traveling toward the vehicle and falls into the target area, the high beam is controlled to turn on.
Specifically, on the basis of the above embodiment, after the vehicle is controlled to be switched from the high beam mode to the low beam mode, the networking object continues to travel, when the networking object travels away from the target area, there is no networking object that travels toward the vehicle and falls into the target area, and then the high beam may be turned on again, and it may be that when it is determined that there is no networking object that travels toward the vehicle and falls into the target area, the high beam is turned on immediately, or after it is determined that there is no networking object that travels toward the vehicle and falls into the target area, the high beam is turned on, which is not limited in this embodiment of the present application.
In the vehicle light control method, the terminal judges whether a target motion trail exists according to the relative motion trail and a target area in front of the vehicle, wherein the target motion trail is the relative motion trail with the direction facing the vehicle and falling into the target area, if the target motion trail exists, the vehicle is controlled to be switched from the high beam mode to the low beam mode, in the embodiment, the vehicle is switched from the high beam mode to the low beam mode and is determined according to whether the relative motion trail with the direction facing the vehicle and falling into the target area exists or not, namely, the vehicle can be controlled to be switched from the high beam mode to the low beam mode according to whether a networking object enters the target area or not in the future, so that the condition that whether the high beam needs to be switched off or not is judged after an oncoming traffic object enters the high beam irradiation area or not is avoided, and then avoided the untimely problem of closing of high beam, improved the security that the vehicle travel.
Further, when the target motion track exists, the terminal can also output prompt information to the user to prompt the user to turn off the high beam. Fig. 4 is a flowchart illustrating a vehicle lamp control method according to another embodiment. The embodiment relates to a specific process of how the terminal controls the vehicle to be switched from the high beam mode to the low beam mode when the target motion track exists. As shown in fig. 4, one possible implementation method of S202 "controlling the vehicle to switch from the high beam mode to the low beam mode if the target motion trajectory exists" includes the following steps:
s301, if the target motion track exists, outputting prompt information; the prompt message is used for prompting the user to turn off the high beam.
Specifically, the prompt information is used for prompting the user to turn off the high beam, wherein the prompt information may prompt the user in a form of voice information, may prompt the user in a form of vibration, and may also prompt the user in a form of light flashing, which is not limited in the embodiment of the present application. In this embodiment, when the terminal determines that the target motion trajectory exists, the terminal may not automatically control the vehicle to switch from the high beam mode to the low beam mode, and may prompt the user to turn off the high beam in a manner of outputting the prompt information.
And S302, receiving a switching instruction input by a user according to the prompt message, and controlling the vehicle to be switched from a high beam mode to a low beam mode according to the switching instruction.
Specifically, when the user receives the prompt information output by the terminal, the user may input a switching instruction according to the prompt information, where the switching instruction is used to instruct to switch the high beam mode to the low beam mode, and of course, the user may not input the switching instruction according to actual needs. When a user inputs a switching instruction, the terminal receives the switching instruction and controls the vehicle to be switched from a high beam mode to a low beam mode according to the switching instruction.
According to the vehicle lamp control method, when the target motion track exists, the prompt information is output; the prompt message is used for prompting a user to close a high beam, receiving a switching instruction input by the user according to the prompt message, controlling the vehicle to be switched from the high beam mode to the dipped beam mode according to the switching instruction, enabling the vehicle to be switched from the high beam mode to the dipped beam mode when a target motion trail exists, outputting the prompt message to prompt the user to close the high beam, and controlling the vehicle to be switched from the high beam mode to the dipped beam mode according to the switching instruction input by the user when receiving the switching instruction input by the user, so that the vehicle is switched from the high beam mode to the dipped beam mode, which can be automatically switched when the target motion trail exists, or can be switched when the target motion trail exists, through prompting the user, and the vehicle lamp control flexibility is improved under the condition of ensuring the driving safety.
The above embodiments mainly describe a specific process of how the terminal controls the on state of the vehicle lamp, and the following embodiments describe in detail a specific process of how the terminal obtains a relative motion trajectory of the networked object with respect to the vehicle in the target time period. Optionally, the relative motion trajectory is obtained from predicted trajectories of the networked object and the vehicle over the target time period.
Specifically, the predicted trajectory may refer to a travel trajectory in a period of time after the current time. The relative motion trajectory may be derived from a predicted trajectory of the networked object over the target time period and a predicted trajectory of the vehicle over the target time period. For example, the predicted position information of the networked object at each time in the target time period can be determined according to the predicted track of the networked object in the target time period, the predicted position information of the vehicle at each time in the target time period can be determined according to the predicted track of the vehicle in the target time period, the predicted relative position information of the networked object relative to the vehicle at each time in the target time period can be obtained according to the predicted position information of the networked object at each time in the target time period and the predicted position information of the vehicle at each corresponding time in the target time period, and the relative motion track can be obtained by integrating the predicted relative position information of the networked object relative to the vehicle at each time.
Optionally, predicting a predicted trajectory of the networked object according to the historical motion trajectory of the networked object; alternatively, the predicted trajectory of the networked object is extracted from navigation information of the networked object.
Specifically, the historical motion trajectory may be a motion trajectory of an intranet object in a period of time before the current time, and the historical motion trajectory may be obtained according to positioning information of a networked object or a motion direction of the networked object. When the historical motion trajectory of the networked object is obtained, a predicted trajectory of the networked object may be predicted from the historical motion trajectory. For example, if the historical motion trajectory of the networked object is traveling toward the vehicle and traveling at a constant speed of 10 km/h, the predicted trajectory of the networked object may be predicted to travel toward the vehicle and travel at a constant speed of 10 km/h. Or, the terminal may also predict the predicted trajectory of the networked object by obtaining navigation information of the networked object, where the navigation information may include a driving trajectory of the networked object after the current time and times corresponding to respective positions in the driving trajectory. And the terminal extracts the future driving track of the networked object from the navigation information of the networked object as a predicted track. The terminal can predict and obtain the predicted track of the networking object according to the historical motion track of the networking object; or the future driving track of the networked object can be independently extracted from the navigation information of the networked object to be used as a predicted track; the predicted trajectory can also be obtained by combining the two methods, which is not limited in the embodiment of the present application.
On the basis of the above embodiment, before controlling the on-state of the lamps of the vehicle according to the relative motion trajectory and the target area in front of the vehicle, the target area in front of the vehicle may be determined according to the high beam parameter information. Optionally, determining a target area according to the high beam parameter information of the vehicle; the high beam parameter information includes the orientation of the high beam, the height of the high beam, and the illumination intensity of the high beam.
Specifically, high beam parameter information can include high beam orientation and high beam height, wherein, the high beam orientation can include that the high beam shines towards the left, the high beam shines towards the right, the high beam shines upwards, or the high beam shines downwards, this application embodiment does not do the restriction to this, and further, the high beam orientation still includes the angle of high beam orientation, for example, the high beam orientation is for facing left 30 °. The high beam height can be the height of high beam center distance ground, also can be the height of high beam center distance automobile body downside most, and this application embodiment does not do the restriction to this. The illumination intensity of the high beam can represent the farthest irradiation distance of the high beam. The terminal can confirm the high beam irradiation area according to the high beam parameters. The terminal can directly determine the irradiation area of the high beam lamp as the target area, and can also enlarge the irradiation area of the high beam lamp according to a preset distance threshold value to obtain the target area.
According to the vehicle lamp control method, the target area is determined according to the high beam parameter information of the vehicle, wherein the high beam parameter information comprises the orientation of the high beam, the height of the high beam and the illumination intensity of the high beam. In this embodiment, the target area is determined according to the high beam parameter information, so that the terminal controls the on-state of the vehicle lamp according to the relative motion track of the networked object relative to the vehicle in the target time period and the target area determined according to the high beam parameter information in front of the vehicle, thereby further avoiding the situation that whether the high beam needs to be turned off or not after the traffic object running in opposite direction enters the high beam irradiation area, further avoiding the problem that the high beam is not turned off timely, and improving the driving safety of the vehicle.
On the basis of the above embodiment, the terminal may further prohibit the automatic control of the lamp-on state of the vehicle according to the relative motion trajectory and the target area, according to a prohibition instruction input by the user. This is described in detail below with respect to the embodiment shown in fig. 5.
Fig. 5 is a flowchart illustrating a vehicle lamp control method according to another embodiment. The embodiment relates to a specific process of controlling the lamp-on state of a vehicle according to a prohibition instruction input by a user. As shown in fig. 5, one possible implementation method of the above S102 "controlling the lamp-on state of the vehicle according to the relative motion trajectory and the target area in front of the vehicle" includes the following steps:
s401, judging whether a prohibition instruction input by a user is received; the prohibition instruction is used for indicating that the control of the lamp starting state of the vehicle according to the relative motion track and the target area is prohibited; if not, go to S402.
Specifically, the prohibition instruction may be used to instruct to prohibit controlling the on-state of the vehicle lamp of the vehicle according to the relative motion trajectory and the target area, and may be a voice instruction or a touch instruction, which is not limited in this embodiment of the present application. For example, when the prohibition instruction is a voice instruction, it may be determined whether a prohibition instruction input by a user is received by determining whether a voice indicating prohibition of controlling the on-state of the lamps of the vehicle in accordance with the relative movement locus and the target area is received. And when a prohibition instruction input by a user is received, prohibiting the on state of the vehicle lamp from being controlled according to the relative motion track and the target area in front of the vehicle.
