Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A vehicle and a communication system thereof according to an embodiment of the present invention will be described below with reference to the drawings.
Fig. 1 is a block diagram of a vehicle according to an embodiment of the present invention.
As shown in fig. 1, the vehicle 100 includes: a first transmitter 101, a first receiver 102, a first processor 103, a first controller 104.
Specifically, the first transmitter 101 is arranged corresponding to an external stable light source of the vehicle 100, the first transmitter 101 may be a chip added in a light source such as an on-board LED, a laser, etc., and the vehicle 100 may drive the corresponding light source to transmit information through the first transmitter 101; the first receiver 102 is arranged on the body of the vehicle 100 and is used for receiving visible light information emitted by a roadside light source and/or an external stable light source of other road vehicles; the first processor 103 is connected to the first transmitter 101 and the first receiver 102, and configured to identify a source of the visible light information received by the first receiver 102, obtain first traffic information according to the source and the visible light information corresponding to the source, and control the first transmitter 101 according to the first traffic information, so that the corresponding external stable light source emits corresponding visible light information; the first controller 104 is connected to the first processor 103, and is configured to control the vehicle 100 according to the first traffic information. After receiving the visible light information, the vehicle 100 can be used without performing analysis processing such as format conversion and demodulation on the information.
The other road vehicles may include at least one of an ambulance, a fire truck, and a dangerous vehicle, so that the first controller 104 may control the vehicle 100 to avoid in time when the first processor 103 determines that there is an ambulance, a fire truck, or a dangerous vehicle according to the visible light information. The roadside lamp includes at least one of a street lamp, a building lamp, a traffic light, and may further include a laser lamp, an illumination lamp, etc. carried by a pedestrian.
Optionally, the first transmitter 101, the first receiver 102, the first processor 103, and the first controller 104 may be mounted on the external steady light source of the other road vehicle. The drive test lamp may be provided with a transmitter, a receiver, and a processor, so that the drive test lamp can communicate with the vehicle 100 on the road through the transmitter, the receiver, and the processor. The transmitter and the receiver mounted on the road test lamp are an optical transmitter and an optical receiver for transmitting and receiving communication light; other types of transmitters and receivers may also be included.
The external stabilization light source of the vehicle (including the vehicle 100 and other road vehicles) is preferably a lamp corresponding to the vehicle; other optical communicators mounted on the vehicle for emitting visible light signals are also possible.
As one example, as shown in FIG. 2, the vehicle 100 described above may also include an onboard detection device 105. The vehicle-mounted detection device 105 is connected with the first controller 104, and the vehicle-mounted detection device 105 is used for acquiring second traffic road condition information; the first processor 103 is further configured to send an arbitration request to the first controller 104 when the number of sources is greater than a preset value; the first controller 104 is further configured to compare the first traffic information with the second traffic information according to the arbitration request, and control the vehicle 100 to stop emergently when a difference between the first traffic information and the second traffic information satisfies a preset condition. The on-vehicle detection device 105 may be, among other things, a sensor mounted on the vehicle 100, such as a camera, an on-vehicle radar, or the like.
Specifically, a preset value may be preset, and if the number of sources (e.g., 5 sources are other road vehicles, 3 sources are street lamps, one is a traffic light, etc.) is greater than the preset value (e.g., 5), it indicates that the current road condition is more complicated. In order to adapt to the situation, after the vehicle 100 acquires the first traffic road condition information, the vehicle 100 may also acquire traffic road condition information around itself according to the vehicle-mounted detection device 105 installed on itself, and use the traffic road condition information as second traffic road condition information; and comparing the difference between the first traffic road condition information and the second traffic road condition information, and if the difference between the first traffic road condition information and the second traffic road condition information is greater, controlling the vehicle 100 to stop emergently. For example, the information of 200 meters ahead is obtained, the information of the first traffic information and the information of the second traffic information at the same target point are compared, and when a large deviation exists, that is, a target that can be identified in one information cannot be identified in the other information, if the obstacle exists in the road is judged by the second traffic information and cannot be identified by the first traffic information, the first controller 104 controls the vehicle 100 to stop emergently to ensure the driving safety.
Alternatively, the vehicle 100 may send the second traffic condition information acquired by the vehicle-mounted detection device 105, such as whether there is an obstacle on the road, the size of the obstacle, whether the road is traffic jam, and the like, in the form of visible light information, so that the second traffic condition information is received by a receiver corresponding to a nearby street lamp and/or traffic light, and is sent out after being processed.
As an example, when the first processor 103 determines that the light source includes only a street lamp and/or a traffic light, or determines that the road segment where the vehicle 100 is located is a first preset road segment, the first controller 104 may suspend data interaction with the on-board detection device 105, and thus, energy consumption may be reduced. The first preset road section may be a road section with a simpler road condition, for example, an automatic driving road section, a highway section, a road section with a perfect leveling rule or a less accident.
As an example, a second preset road segment may be preset, and a communication connection exists between a street lamp and a traffic light in the second preset road segment, that is, a communication connection exists between a street lamp and a traffic light in the road segment, a communication connection exists between a street lamp and a traffic light, a communication connection exists between a communication light and a communication light, and the communication connection may be a visible light communication, a wifi communication, or the like. For example, if two street lamps are within the illumination range of the communication light emitted by the light emitters of the other street lamps, the two street lamps are directly communicated through the communication light; if the light emitters are not in the illumination range of the communication light emitted by the light emitters of the opposite side, the communication can be carried out through wifi.
Therefore, when the vehicle 100 determines that the source includes a street lamp or a traffic light of the second preset road section according to the visible light information, all street lamps and/or traffic light states of the second preset road section can be acquired according to the corresponding visible light information. Specifically, each street lamp or traffic light on the second preset road section becomes a communication node, and a communication network is formed together. Each street lamp or traffic light acquires first traffic road condition information corresponding to the street lamp or traffic light; thus, the vehicle 100 may communicate with any one of the street lamps or traffic lights to obtain the first traffic information of the second preset road section in a wide range (for example, the first traffic information of the vehicle 100 may be 300 meters before and after the vehicle). So that the vehicle 100 can be controlled according to the first traffic condition information.
As an example, as shown in fig. 3, the vehicle 100 may further include a first modem 106. The first modem 106 is connected with the first processor 103; the processor is further configured to determine whether the vehicle 100 is located in a third preset road section according to the corresponding visible light information when the source includes a street lamp, receive the visible light modulation information through the first modem 106 when the vehicle 100 is located in the third preset road section, and demodulate the visible light modulation information through the first modem 106.
In particular, since visible light information is generally a digital signal that is converted into light and dark. Therefore, if it is determined that the vehicle 100 is located in the third preset road segment, other road vehicles can modulate and transmit the first traffic information required to be transmitted by themselves through the first modem 106; for example, carrier communication may be implemented by the first modem module to load an ultra-large amount of modulated information. This allows the visible light signal to contain more information. The vehicle 100 then demodulates the modulated visible light signal by its own first modem module. The third preset road section may be a road section with sufficient visible light.
As an example, at least one of entertainment, news, and weather information may be further included in the visible light information, and thus, the first processor 103 may further obtain at least one of entertainment, news, and weather information from the visible light information; the first controller 104 is also used for controlling the vehicle terminal of the vehicle 100 to broadcast at least one of entertainment, news, and weather information.
In summary, the vehicle according to the embodiment of the present invention can acquire road information in an optical communication manner to control the vehicle. In addition, the control mode of the vehicle can be changed according to the specific road mode, so that the vehicle control system can better adapt to different road modes, and the use experience of a user is improved.
