Description

Technical Field

[0001] The present invention relates to the field of multi-vehicle cooperation, and in particular to a control method for multi-vehicle light synchronization. Background Art

[0002] At present, multi-vehicle cooperative autonomous driving technology has received wide attention, but there is still a lack of an effective control method and control platform to intelligently combine a single vehicle with multi-vehicle cooperative autonomous driving, which hinders developers from automatically controlling vehicles in various different states and with different devices.

[0003] The existing solution is that different vehicles communicate with the same central platform through networking (wifi or 4G), and the central platform issues commands to achieve time synchronization between vehicles and execute operation commands. This method has very high uncertainty in actual scenarios. On the one hand, due to the uncontrollable volatility and delay of the network itself, it is impossible to ensure precise synchronization of multiple vehicles. On the other hand, when there are many vehicles, there is a scheduling interval for the server to issue commands, resulting in a time difference in the commands received by different vehicles.

[0004] For example, a "method, device, vehicle, and readable medium for synchronizing the headlights of multiple vehicles" disclosed in a Chinese patent document connects multiple vehicles to the same wireless local area network WLAN based on in-vehicle terminals to achieve the purpose of controlling the light synchronization of multiple vehicles, including the problem that there is a large uncertainty in actual scenarios and it is impossible to ensure precise synchronization of multiple vehicles. Summary of the Invention

[0005] The present invention is to solve the problem that the method of realizing multi-vehicle light synchronization through networking in the prior art has high uncertainty and cannot ensure precise synchronization of multiple vehicles. A control method for multi-vehicle light synchronization is provided, which uses a key as a multi-vehicle synchronization source, simplifies the design, has high stability, customizes the button functions using the key buttons, has high flexibility, and has a very good display effect in scenarios that require a performance nature such as vehicle press conferences and mall performances.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A control method for multi-vehicle light synchronization, characterized by including the following steps:

[0008] Step S1: Match the same key source for the demonstration vehicles;

[0009] Step S2: Modify the action definition of the key buttons;

[0010] Step S3: Write a light control program through the vehicle built-in system;

[0011] Step S4: the vehicle's internal controller waits for a key button instruction;

[0012] Step S5: multiple demonstration vehicles receive the start command at the same time;

[0013] Step S6: After receiving the instruction, multiple vehicles run the lighting program simultaneously.

[0014] Using the car key as the synchronization source, by configuring the same key for different vehicles and using the key button of the key as the signal source, the vehicle lighting synchronization state is controlled by the key button action, so that multiple demonstration vehicles can make corresponding lighting actions according to the corresponding key commands.

[0015] Preferably, step S1 matches the same key source to several different demonstration vehicles, and uses the key buttons matched by the same key source as the signal source to ensure the stability of the control method and the control system.

[0016] Preferably, step S2 resets and redefines the function of the key button. When the vehicle controller receives the key command, it defines the trunk button and the car search button as start or end commands, and uses the key button to customize the button function, thereby improving the flexibility of the control method.

[0017] Preferably, the key customization function is expanded according to the key model, additional functions are added by long pressing or short pressing the key button, the function is expanded according to the matching degree of the key customization function with different key models, more functions are added by combining long pressing or short pressing of buttons, and it is carried out according to specific light show needs to improve the flexibility of the control method.

[0018] Preferably, in step S5, when the body controllers of multiple demonstration vehicles receive the key command, the lighting execution program is triggered to start. The key control adopts 300Mhz~450Mhz wireless communication, and in the process of multi-light synchronization, the key can control the early end or reset of the running lighting program. The lighting execution program process can be controlled to end early or reset the operation by a single key button to terminate the current lighting working state of multiple vehicles early, thereby realizing multi-vehicle synchronization source, simplifying the design, and having extremely high stability of the control method.

[0019] Signals are received via radio waves, and do not require connection, handshake protocol interaction or other communication processes. Signal sending and receiving will not be subject to much signal interference. Radio travels at the speed of light, so multiple vehicles can receive control signals at the same time without any action delays.

[0020] A lighting synchronization system adopts the above working method, and provides a lighting synchronization system, including a terminal module, an input-output module, a power supply module, a central control module and an execution module, wherein the terminal module includes a sending end and a receiving end of a lighting synchronization signal, the sending end is connected to the input-output module, the input-output module is connected to the receiving end, the central control module is connected to the input-output module for signal conversion, the execution module is connected to the receiving end signal, and the input-output module, the central control module and the execution module are electrically connected to the power supply module; the sending end is used to transmit an initial synchronization signal to the input-output module, and the receiving end is used to receive an execution signal sent from the input-output module, the first synchronization signal includes a lighting synchronization signal, and the execution signal includes a lighting synchronization execution signal.

[0021] The input-output module is used to receive the lighting synchronization signal sent by the sending end, send the lighting synchronization signal to the central control module, and simultaneously receive the lighting synchronization execution signal sent from the central control module, and after receiving, send the lighting synchronization execution signal to the receiving end; the central control module receives and processes the lighting synchronization signal sent from the input-output module, converts the lighting synchronization signal into a lighting synchronization execution signal, and sends the lighting synchronization signal to the input-output module, the input-output module sends the execution signal to the receiving end, and after the receiving end receives the signal, the execution module executes the current program.

[0022] Preferably, the input-output module includes a wireless sending module and a wireless receiving module.

[0023] Therefore, the present invention has the following beneficial effects:

[0024] Use keys to achieve multi-vehicle synchronization source, simplify design and have high stability;

[0025] The button functions can be customized by key buttons, which has high flexibility.

[0026] The lighting synchronization system achieves lighting synchronization through wireless signal conversion, improving the accuracy of the lighting synchronization process of multiple vehicles;

[0027] The lighting actions of multiple vehicles are performed synchronously, which has a very good display effect in scenes that require performances, such as vehicle launches and shopping mall performances, and improves the viewing experience of the actual performance process.

[0029] Figure 2 It is a structural principle diagram of the lighting synchronization system of the present invention. DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] As Figure 1 shown, the present invention uses an automobile key as a synchronization source. By configuring the same key for different vehicles, it is realized that the demonstration vehicle can control the lighting program through the corresponding key instruction and perform the corresponding lighting operation, which specifically includes the following steps:

[0032] Step S1: Match the same key source for the demonstration vehicle;

[0033] Step S2: Modify the action definition of the key button;

[0034] Step S3: Write the lighting control program through the vehicle built-in system;

[0035] Step S4: The vehicle body internal controller waits for the instruction of the key button;

[0036] Step S5: Multiple demonstration vehicles receive the start instruction simultaneously;

[0037] Step S6: Multiple vehicles run the lighting program simultaneously after receiving the instruction.

[0038] Using the automobile key as a synchronization source, by configuring the same key for different vehicles and using the key button of the key as a signal source, the lighting synchronization state of the vehicle is controlled through the key button action, so that multiple demonstration vehicles can make corresponding lighting actions according to the corresponding key instructions.

[0039] In step S1, multiple different demonstration vehicles are matched with the same key source, and the key button matched by the same key source is used as a signal source to ensure the stability of the control method and control system.

[0040] In step S2, the function of the key button is reset and redefined. When the vehicle controller receives the key instruction, the trunk button and the car-finding button are defined as start or end instructions, and the button function is customized by using the key button, so as to improve the flexibility of the control method.

[0041] In step S3, a lighting controller is set, and different lighting demonstration programs are written into the lighting controller according to different scene requirements, and different lighting actions in different scenes are matched by matching different lighting demonstration programs with the key source actions.

[0042] The key customization function expands the function according to the key model. By long-pressing and short-pressing the key button, additional functions are added. The function is expanded through the matching degree of the key customization function with different key models. By combining the long-pressing and short-pressing methods of the button, more functions are added, which is carried out according to the specific lighting show requirements to improve the flexibility of the control method.

[0043] In step S5, when the body controllers of multiple demonstration vehicles receive the key command, the light execution program is triggered to start. The key control adopts 300Mhz~450Mhz wireless communication, and in the process of synchronous operation of multiple lights, the key can control to end or reset the running light program in advance. The light execution program process is controlled by a single key button to end or reset the operation in advance to terminate the current light working state of multiple vehicles in advance, realize multi-vehicle synchronization source, simplify the design, and have extremely high control method stability; signals are received through radio waves, and there is no need for connection, handshake protocol interaction and other communication processes. The signal sending and receiving process will not be subject to much signal interference. At the same time, radio propagates at the speed of light. Therefore, multiple vehicles can receive control signals at the same time without action delay.

[0044] In step S6, after the multiple vehicles simultaneously receive the light start command, the multiple demonstration vehicles simultaneously operate and execute the corresponding light program according to the actual command.

[0045] like Figure 2 As shown, in order to match the above-mentioned multi-vehicle lighting synchronization control method, a lighting synchronization system is introduced, including a terminal module, an input-output module, a power supply module, a central control module and an execution module, the terminal module includes a sending end and a receiving end of a lighting synchronization signal, the sending end is connected to the input-output module, the input-output module is connected to the receiving end, the central control module is connected to the input-output module for signal conversion, the execution module is connected to the receiving end signal, the input-output module, the central control module and the execution module are electrically connected to the power supply module; the sending end is used to transmit an initial synchronization signal to the input-output module, the receiving end is used to receive an execution signal sent from the input-output module, the first synchronization signal includes a lighting synchronization signal, and the execution signal includes a lighting synchronization execution signal.

[0046] The input-output module is used to receive the lighting synchronization signal sent by the sending end, send the lighting synchronization signal to the central control module, and simultaneously receive the lighting synchronization execution signal sent from the central control module, and after receiving, send the lighting synchronization execution signal to the receiving end; the central control module receives and processes the lighting synchronization signal sent from the input-output module, converts the lighting synchronization signal into a lighting synchronization execution signal, and sends the lighting synchronization signal to the input-output module, the input-output module sends the execution signal to the receiving end, and after the receiving end receives the signal, the execution module executes the current program.

[0047] The input-output module includes a wireless sending module and a wireless receiving module.

[0048] Synchronization of the lighting states of the sending end and the receiving end: A lighting synchronization system according to this embodiment connects the terminal module to the input / output module, enabling the terminal module to establish a connection relationship with the central control module. Meanwhile, the receiving end in the terminal module is electrically connected to the execution module. The lighting state information of the sending end in the terminal module will be sent as the first synchronization signal to the central control module. The central control module receives and processes this information, thereby learning the lighting state information of the sending end. Subsequently, the central control module sends the second synchronization signal to the receiving end to control the lighting state of the receiving end to always be consistent with that of the sending end. Through the lighting synchronization system of this embodiment, the lighting of the sending end and the receiving end is kept synchronized, enhancing the display effect of the overall demonstration vehicle of the terminal module.

[0049] The terminal module is set at the vehicle key button. Using the car key as the synchronization source, by configuring the same key for different vehicles and taking the key button of this key as the signal source, the lighting synchronization state of the vehicle is controlled through the key button operation, and the lighting program is written into the lighting synchronization system to match the lighting programs in different synchronization states under different car key operations. According to the custom functions of the key, the functions are written into the central control module for functional expansion in different directions, and additional functions are added by combining working methods such as long press, short press, contact, and rotation direction of the key button. Different key action functions are set according to the lighting requirements in specific scenarios.
