Description

Technical Field

The main functions of the vehicle lamp are to realize the external illumination of the vehicle and to transmit traffic signals of braking, steering, reversing and the like of the vehicle. With the emphasis of industrial research, the conventional functions of the existing car lamps cannot meet the requirements of users on the technological sense and quality sense of the car. Therefore, a new system scheme for realizing dynamic control of external light of the whole vehicle, which can integrate light into an external interaction scene of the whole vehicle, needs to be developed.

Existing vehicle light control systems typically employ a Body Control Module (BCM) controller to hard-wire drive the lighting. Specifically, there are two main control schemes for the vehicle lamp, one of which is a direct-triggered type using a hard-wired or serial communication network. The software prestored in the lamp is started through a simple trigger signal transmitted by the upper controller so as to control a Light Emitting Diode (LED) in the vehicle lamp to be lightened according to the lightening sequence prestored in the software, and the dynamic light effect is realized. However, in this scheme, the light can only show the dynamic effect according to the pre-stored mode in the software, and cannot be converted into a dynamic effect other than the pre-stored mode in the software, and the dynamic effect of the vehicle lamp cannot be updated. Another vehicle light control scheme is controller area network communication triggered. Data are exchanged with the gateway and the cloud server through a Controller Area Network (CAN) protocol, and the dynamic mode of the car lamp is downloaded from the cloud server, so that software for realizing the dynamic mode of the car lamp CAN be refreshed and overlapped on line in the scheme. Although the scheme is superior to the first scheme, in the scheme, each vehicle lamp to be controlled needs to be added with a controller local area network transceiver and a microprocessor chip for supporting controller local area network analysis, so that the cost is high. In addition, the resource occupation of the local network of the whole vehicle controller is large when data are downloaded from the cloud server, the updated software needs to be refreshed to the vehicle lamp controllers of all vehicle lamps, the refreshing failure of any one lamp can cause the refreshing failure of all lamps, and the downloading risk is high.

In order to solve the problems of high control cost, large load of a controller local area network and high downloading risk during software updating of a vehicle lamp control system in the prior art, the embodiment of the invention provides the vehicle lamp control system. The vehicle lamp control system provided by the embodiment is used for controlling the vehicle lamp of the vehicle. The vehicle may be an automobile, an electric vehicle, a hybrid vehicle, etc., and the vehicle lights generally refer to exterior lights such as a left headlamp, a right headlamp, a through headlamp, a left side peripheral tail light, a right side peripheral tail light, a through tail light, and a turn signal, a fog light, etc. In some embodiments, the vehicle lamp further includes a dome lamp, an instrument lamp, and the like disposed in the cabin, which is not limited in this embodiment. Specifically, referring to fig. 1, the vehicle lamp control system provided in the present embodiment includes an instruction transceiver module 1 and at least one vehicle lamp control module 2.

The command transceiver module 1 receives vehicle lamp control information input by a user, generates a timing command according to the vehicle lamp control information and sends the timing command. Further, the timing sequence command stores vehicle lamp control parameters. Specifically, the lamp control information input by the user may be a state mode of the lamp selected by the user, for example, a basic driving mode, a parking mode, a high brightness mode, and the like in the daytime or at night, in which commands for controlling the lamps are stored, and when the user selects these fixed modes, the lamps operate according to the lamp states of the modes. Of course, the user can also customize the status of each vehicle light, such as setting the front vehicle light to white, the rear vehicle light to yellow, flashing every three seconds when the turn signal is on, and so on.

Each car light control module 2 is in communication connection with the instruction transceiving module 1, receives the time sequence instruction sent by the instruction transceiving module 1, and controls the car light connected with the car light control module 2 according to the time sequence instruction. Specifically, each vehicle lamp to be controlled has a corresponding vehicle lamp control module 2 to control it. In this embodiment, one lamp control module 2 can be used to control a single lamp, so as to improve the reliability of the system, and one lamp control module 2 can be used to control a plurality of lamps that can be turned on or off simultaneously, so as to reduce the cost of the system.

By adopting the scheme, the light control of the vehicle is changed from a direct triggering mode to a real-time instruction transfer mode, and the real-time sequence instruction replaces a complete LED grouping port calling code, so that the hardware storage capacity requirement of the whole vehicle light controller is greatly reduced on the premise of ensuring the feasibility of the dynamic control of the complex and diversified light effects.

Further, referring to fig. 1, in a preferred embodiment according to the present invention, the instruction transceiver module 1 includes an instruction obtaining part 11, an instruction processing part 12 and an instruction sending part 13. The instruction acquisition part 11 receives and transmits vehicle lamp control information input by a user; the instruction processing component 12 is connected with the instruction acquiring component 11 in a communication mode, and the instruction processing component 12 receives the vehicle lamp control information sent by the instruction acquiring component 11, generates a timing instruction according to the vehicle lamp control information and sends the timing instruction. The instruction sending part 13 is in communication connection with the instruction processing part 12 and each vehicle lamp control module 2, and the instruction sending part 13 receives the timing instruction sent by the instruction processing part 12 and sends the timing instruction to each vehicle lamp control module 2. That is, after the user selects and inputs the state mode of the vehicle lamp, i.e., the vehicle lamp control information via the instruction acquisition unit 11, the instruction processing unit 12 receives the vehicle lamp control information and directly processes the vehicle lamp control information to generate the timing instruction. The timing command is then sent to the command transmitting unit 13, and the timing command is directly sent to each of the vehicle lamp control modules 2 via the command transmitting unit 13. In other words, in a preferred embodiment, the command processing component 12 processes the vehicle light control information to generate the timing command.

Further, referring to fig. 1, in another preferred embodiment according to the present invention, the instruction transceiver module 1 includes an instruction obtaining part 11, an instruction processing part 12 and an instruction transmitting part 13; the instruction acquisition part 11 receives and transmits vehicle lamp control information input by a user; the instruction processing part 12 is connected to the instruction acquiring part 11 in a communication manner, and the instruction processing part 12 receives the lamp control information sent by the instruction acquiring part 11 and sends the lamp control information. The instruction sending part 13 is in communication connection with the instruction processing part 12 and each of the vehicle lamp control modules 2, receives the vehicle lamp control information sent by the instruction processing part 12, generates a timing instruction according to the vehicle lamp control information, and sends the timing instruction to each of the vehicle lamp control modules 2. That is, after the user selects and inputs the state mode of the vehicle lamp, i.e., the vehicle lamp control information via the instruction obtaining portion 11, the instruction processing portion 12 receives the vehicle lamp control information and directly transmits the vehicle lamp control information to the instruction transmitting portion 13. The command transmitting unit 13 receives the vehicle lamp control information, processes the vehicle lamp control information, generates a timing command, and directly transmits the timing command to each of the vehicle lamp control modules 2. In other words, in another preferred embodiment, the command transmitting component 13 processes the vehicle lamp control information to generate the timing command.

Further, referring to fig. 2, in the vehicle lamp control system according to the present invention, the vehicle lamp control system further includes a body controller 3 (BCM), where the body controller 3 is disposed between the command transmitting unit 13 and each of the vehicle lamp control modules 2, and is in communication connection with the command transmitting unit 13 and each of the vehicle lamp control modules 2; the vehicle body controller 3 receives the timing instruction sent by the instruction sending part 13, and forwards the timing instruction to each of the vehicle lamp control modules 2. In the present embodiment, the timing instruction is forwarded through the vehicle body controller 3, and since the vehicle body controller 3 further integrates a control function for other vehicle body components such as a vehicle window, a vehicle door, and a wiper, the vehicle body controller 3 can control the vehicle lamp according to the timing instruction and simultaneously realize linkage control for other vehicle body components. Further, the reliability of the system can be improved by the failure diagnosis function of the vehicle body controller 3 itself.

Further, in the vehicular lamp control system according to the present invention, the instruction processing section 12 and the instruction transmitting section 13 are connected via Controller Area Network (CAN); the instruction transmitting section 13 is communicatively connected to the body controller 3 via a Local Interconnect Network (LIN); the vehicle body controller 3 is in communication connection with each vehicle lamp control module 2 via a serial communication network. With such a communication method, since the vehicle body controller 3 and each of the vehicle lamp control modules 2 are connected to each other through communication via the serial communication network, the LIN bus is less expensive, and therefore, the system cost is reduced and the versatility is improved.

Further, referring to fig. 3, in the lamp control system according to the present invention, the lamp connected to the lamp control module 2 includes a plurality of light emitting diodes 4. Further, the vehicle lamp control module 2 includes a connector 21, a filter protection circuit 22, a communication transceiver 23 (LIN transceiver), and a vehicle lamp controller 24, which are provided in this order in the transmission direction of the timing command. One end of the connector 21 is connected to the vehicle body controller 3 to receive the timing instruction sent by the vehicle body controller 3 and send the timing instruction to the filter protection circuit 22. The filter protection circuit 22 performs filtering processing on the timing command, and sends the processed timing command to the communication transceiver 23. The communication transceiver 23 converts the timing command into a serial bus signal (LIN signal), and transmits the serial bus signal to the lamp controller 24. The vehicle lamp controller 24 stores vehicle lamp basic mode information, the vehicle lamp controller 24 is respectively connected with each light emitting diode 4, the vehicle lamp controller 24 receives serial bus signals, converts the serial bus signals into timing commands for controlling the on and off of each light emitting diode 4, and controls each light emitting diode 4 according to the serial bus signals and the timing commands. It should be noted that, the specific structures, the arrangement positions, and the like of the connector 21, the filter protection circuit 22, and the communication transceiver 23 may refer to the prior art, and the description of the present invention is omitted.

Further, the lamp basic mode information refers to a basic mode in which the lamp is turned on. Six basic modes stored within the vehicle lamp controller 24 are shown with reference to fig. 4. In fig. 4, hatching indicated by oblique lines indicates that the position is not bright. The shading shown by the horizontal lines indicates that the position is brighter than the other positions. The pulse movement is sequentially performed from left to right and from top to bottom, namely the light emitting region moves from right to left in a pulse mode; pixel stacking, i.e. a plurality of discontinuous short light emitting areas moving from left to right; sequentially lighting, namely the vehicle lamp comprises a plurality of areas, and the areas are sequentially lighted from right to left; the pulse moves, namely the middle high-brightness light-emitting area can move in a left-right pulse mode, and the brightness of the surrounding light-emitting area is darker; secondary lighting, namely the car lamp comprises a plurality of areas, and the areas are sequentially changed into high-brightness light from right to left; breath lighting, i.e., breath-type lighting from bottom to top. It should be understood that the above six modes may set different lighting directions according to the position of the actual vehicle lamp, and are not limited to lighting from left to right or from right to left. When the vehicle lamp control information input by the user is not received, the vehicle lamp can work in the six basic modes. After receiving the vehicle lamp control information input by the user, the six basic modes can be further changed and improved according to the vehicle lamp control information. Therefore, the innovative scene function of generating intelligent control light effect by user-defined editing is realized through the parameterized dynamic control mode, namely the basic mode, stored in the vehicle lamp controller 24. The comprehensive design of the basic mode realizes the continuous use of software architecture in the lamp among different projects, and the software of the vehicle lamp controller for controlling the vehicle lamp does not need to carry out brand new design on each project any more, and only needs to carry out bottom fine adjustment according to hardware LED grouping difference. The change of the light control effect of the whole vehicle can be simply realized by directly changing the upper time sequence instruction. Thus, the efficiency of the vehicle lamp control is improved.

Further, referring to fig. 1, in a preferred embodiment according to the present invention, the vehicle lamp control system further includes a vehicle networking communication device 5 (T-box), and the vehicle networking communication device 5 and the command sending component 13 are connected in communication via a controller area network and in communication via an ethernet network with the cloud server 6.

By adopting the scheme, the vehicle lamp controller 24 is not required to download the updating data automatically, the real-time instruction is directly downloaded, stored and issued by the instruction sending component 13, and the problems of overhigh network load and high download failure probability caused by the fact that the vehicle lamp controller 24 automatically downloads the updating data through the controller local area network communication are solved.

Still further, referring to fig. 1, in a preferred embodiment according to the present invention, the instruction processing section 12 is further connected in communication with a vehicle-end load controller 7 of the vehicle, and the vehicle-end load controller 7 is connected with a vehicle-end load 8 of the vehicle. The instruction processing part 12 also generates load control information from the vehicle lamp control information input by the user; the vehicle end load 8 receives the load control information sent by the instruction processing part 12 and sends the load control information; and the vehicle-end load controller 7 controls the working state of the vehicle-end load 8 according to the load control information. Specifically, the end load 8 includes, but is not limited to, a horn, and other components provided on the vehicle body. The vehicle-end load controller 7 can also be a device for controlling the vehicle-end load 8, and a person skilled in the art can select a specific model according to actual requirements. With such a configuration, load control information is generated according to vehicle lamp control information input by a user, and the vehicle-side load 8 is controlled according to the load control information, so that the vehicle-side load 8 and the vehicle lamp can be linked, and the experience of the user can be improved.

Further, the instruction acquisition component 11 is a vehicle-mounted central control panel, and the instruction processing component 12 is any one of an information management controller (ICM), an entertainment host controller, and a vehicle control unit, and may be other controllers having a control function. The command transmitting unit 13 is any one of an In Car Communication (ICC), a gateway, and a vehicle controller, but may be another controller having a control function. At least two of the instruction acquisition unit 11, the instruction processing unit 12, and the instruction transmission unit 13 are integrated into one unit. That is, the instruction acquisition unit 11 and the instruction processing unit 12 may be integrated, the instruction acquisition unit 11 and the instruction transmission unit 13 may be integrated, the instruction processing unit 12 and the instruction transmission unit 13 may be integrated, and the instruction acquisition unit 11, the instruction processing unit 12, and the instruction transmission unit 13 may be integrated. Specifically, when the instruction acquisition unit 11 is an in-vehicle center control screen, the instruction acquisition unit 11 may be integrated with either or both of the instruction processing unit 12 and the instruction transmitting unit 13. When the instruction acquisition section 11 is a mobile terminal, the instruction processing section 12 and the instruction transmission section 13 may be integrated. It should be noted that, the integration between the components depends on the hardware operation and driving capability of the actual vehicle controller, and the present embodiment is not limited thereto.

Further, referring to FIG. 5, the sequential instructions are binary codes. In fig. 5, the single signal scheduling, i.e. generating and sending a sequential instruction, is in binary form, the instruction length includes ten frames and twenty bits, and the compiling and converting mode is also a binary code compiling mode. However, in other embodiments, the binary form, the instruction length, and the compiling conversion mode may also adopt other modes, for example, the binary form of the instruction is 10-ary, 16-ary, and the like. The lamp controller 24 performs segment recognition to resolve codes of different digits, for example, 1 to 5 digits for mode, 6 to 11 digits for start-up latency, 12 to 17 digits for duration, and 18 to 21 digits for brightness setting.

The vehicle lamp control parameters comprise basic lighting parameters, intelligent control parameters and state feedback parameters; the intelligent control parameters further comprise vehicle lamp modes, duration, waiting time and brightness. Referring to fig. 6, taking 100ms as a scheduling period, i.e. a period for generating and sending the command, 6 external light fixtures participate in the interactive function as an example. The scheduling mode of the time sequence command signal of the dynamic light control adopts LIN scheduling, the scheduling period determines the switching frequency of the final dynamic light mode, and the information content contained in each scheduling comprises a basic lighting function, namely basic lighting parameters, namely lighting or not lighting of the vehicle; the respective instruction control instructions of different external lamp nodes, namely intelligent control parameters, namely the states and modes of the lamps, the brightness of each lamp at a certain moment, the duration of the state and the like; and (3) real-time lighting state feedback of each node, namely state feedback parameters, namely whether each car lamp is lighted or not in real time. By the mode, the most basic state of the vehicle lamp lighting or not lighting can be selected, the state of the vehicle lamp can be further set and changed, and the dynamic effect of the vehicle lamp is improved.

In the present embodiment, a description will be given taking 100ms as one scheduling cycle, that is, a cycle in which commands are generated and transmitted, as an example. In fact, the scheduling period may also be 50ms, 150ms, 200ms, or other time period. Of course, in some cases, the event frame format may also have application feasibility, which may be determined according to the actual network resource of the entire vehicle or the resolution requirement of the animation, and this embodiment does not limit this.

It should be noted that the instruction acquisition unit 11 may also be a mobile terminal. That is to say, the user can network the mobile phone and the vehicle, and directly input the vehicle lamp control information through the mobile phone to control the vehicle lamp. Referring to fig. 7, a user can directly define the music effect of the car lights at the central control screen or the APP end of the mobile phone, that is, the state of each car light is set by self-definition after a song is selected, and the car light parameters selected on the interface of the central control screen or the mobile phone, such as mode selection, waiting time, duration, brightness, and the like, can be converted into binary codes, so as to transmit the dynamic effect of controlling each light. The user selects personalized music, and then drags each sub-mode to a stepping point on the time axis corresponding to the music completion, so that a new dynamic effect of the whole vehicle can be generated at any time.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a more detailed description of the invention, taken in conjunction with the specific embodiments thereof, and that no limitation of the invention is intended thereby. Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the invention.
