Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted LED lighting effect control, and in particular to a wired and wireless hybrid atmosphere light control system and method based on an accelerator engine. Background Art

[0002] Car ambient lighting has become an indispensable part of car interiors. Traditional ambient lighting control is based on the CAN / CANFD communication protocol, which not only requires the selection of ICs with integrated CAN / CANFD functions; at the same time, due to the reliability considerations of the CAN / CAN FD standard data protocol, it contains more verification information, resulting in low transmission efficiency, which is not conducive to data transmission of large-scale lighting effect scenes.

[0003] The existing technology uses UartOnCAN as an alternative to standard CAN / CANFD, but if the ambient lights are arranged in the whole vehicle space, the problem of too many communication harnesses becomes obvious. If all ambient lights use wireless communication, although the number of communication lines can be greatly reduced, since each lighting node needs to add a wireless communication module, it is not possible to control the cost of parts.

[0004] If UartOnCAN and wireless communication are mixed, a balance can be found between wiring convenience and cost control, which is an ideal solution. However, due to the existence of two different data transmission channels, when the number of LED lamp beads reaches hundreds or thousands, how to coordinate the synchronous changes of lights in different channels and combine them to form lighting effects greatly increases the difficulty of software development. Summary of the invention

[0005] The purpose of the present invention is to provide a wired-wireless hybrid atmosphere light control system and method based on an accelerator engine. The system and method use the routing scheduling design of the "atmosphere light flow accelerator engine system" to hide the underlying communication details, thereby greatly simplifying the difficulty of developing the software application layer, and enabling the "wired + wireless hybrid" architecture atmosphere light of large-scale LED lamp beads to be realized.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A wired and wireless hybrid atmosphere light control system based on an accelerator engine includes an atmosphere light controller connected to a vehicle upper controller, wherein the atmosphere light controller is provided with an application layer, an engine layer and a driver layer, and the key points are:

[0008] The engine layer is provided with an accelerator engine, a routing distribution module and N LED simulation modules;

[0009] The driving layer is provided with an LED wired driving module and a wireless communication driving module;

[0010] The accelerator engine is respectively connected to N virtual LED modules, the N virtual LED modules are directly connected to the routing distribution module, the routing distribution module is respectively connected to the LED wired drive module and the wireless communication drive module, and the LED wired drive module and the wireless communication drive module are respectively connected to N LED lamp templates.

[0011] The accelerator engine calls the lighting script information, and the routing allocation module queries the allocation path according to the lighting script information, and transmits the lighting script information to the corresponding LED wired driver module and wireless communication driver module. The LED wired driver module and the wireless communication driver module drive the corresponding LED light template to light up, coordinate the synchronous changes of lights on different channels, realize wired and wireless hybrid, and solve the convenience and cost control issues of communication wiring in the layout of atmosphere lights in the entire vehicle space.

[0012] The LED wired driver module and the wireless communication driver module have the same API call interface format open to the upper layer;

[0013] The API calling interface formats being completely identical refers to calling the same set of function names to perform the same logical operations.

[0014] The API calling interface format is exactly the same. For the accelerator engine, it only performs the same operation logic for the same virtual LED module, so there is no need to pay attention to the underlying hardware implementation. By developing applications through the API interface program, it can reduce the writing of useless programs and reduce programming tasks, thereby greatly simplifying the difficulty of software application layer development.

[0015] The accelerator engine is bidirectionally connected to a virtual flash memory, which is arranged in the engine layer. The virtual flash memory is bidirectionally connected to a flash driver module, which is arranged in the driver layer. The flash driver module is bidirectionally connected to the flash memory.

[0016] The flash memory is used to store various lighting script information, ensuring the integrity and accuracy of the lighting script information. The virtual flash memory increases the utilization of the atmosphere light controller and the throughput of the system, and can simplify the task of programming.

[0017] The flash memory may be arranged in the atmosphere light controller;

[0018] The flash memory may be arranged outside the atmosphere light controller.

[0019] The flash memory can be built-in or external, and can be selected according to actual conditions to improve the flexibility of the system.

[0020] The vehicle upper controller is connected to the atmosphere light controller via a CAN / LIN bus.

[0021] CAN bus has the characteristics of multi-node connection, high reliability, high communication rate and low latency, which can improve data transmission efficiency, weaken the data error rate and control it within a limited small range to ensure the quality of data transmission. CAN bus combined with LIN bus can further reduce wiring costs on the basis of ensuring data transmission efficiency and quality.

[0022] A wired and wireless hybrid atmosphere light control method based on an accelerator engine comprises the following steps:

[0023] Step 1: The vehicle upper controller sends a command to the application layer, and the application layer notifies the accelerator engine;

[0024] Step 2: The accelerator engine reads the lighting script information in the flash memory;

[0025] Step 3: The accelerator engine writes the lighting script information into the corresponding virtual LED module, performs path pre-matching, and sends the path pre-matching result to the routing allocation module;

[0026] Step 4: The accelerator engine notifies the routing allocation module, which calls the "domain allocation table" to query the driver program path and transmits the lighting script information to the corresponding LED wired driver module or wireless communication driver module;

[0027] Step 5: The LED wired driver module or the wireless communication driver module performs protocol conversion and sends the converted data to the corresponding LED light template to drive the LED light template to light up.

[0028] Through the above steps, the accelerator engine combined with the routing distribution module, LED wired drive module and wireless communication drive module can coordinate the synchronous changes of lights in different channels, realize wired and wireless hybrid, and solve the convenience and cost control issues of communication wiring in the layout of ambient lights in the entire vehicle space.

[0029] In step 1, the application layer obtains instructions from the vehicle upper controller through the CAN / LIN bus, parses the instructions and notifies the accelerator engine according to the instructions;

[0030] The CAN bus has high reliability, high communication rate and low latency, and can quickly and accurately transmit instructions from the vehicle's upper-level controller to the accelerator engine.

[0031] In step 2, the flash driver module calls the lighting script information in the flash memory, transmits the lighting script information to the virtual flash memory, and the accelerator engine reads the lighting script information through the virtual flash memory;

[0032] The lighting script information includes lighting script data, "domain allocation table" and "domain address".

[0033] Each atmosphere light main controller will customize a "domain allocation table" according to customer needs and save it in the firmware. The "domain allocation table" records the driver object to be called corresponding to each "domain address" and inserts the "domain address" into the lighting script data to achieve a one-to-one correspondence between the "domain address" and the lighting script data, making it convenient for the subsequent routing allocation module to analyze the route and match the path.

[0034] In step 3, the "domain address" corresponds to the lighting script data one by one, and the accelerator engine writes the corresponding lighting script information into the corresponding virtual LED module according to the "domain address".

[0035] The virtual LED module performs path pre-matching, provides reliable data for the routing distribution module to analyze the route, and improves the accuracy of the routing distribution module's allocation.

[0036] In step 4, each time the routing allocation module receives a path query request, it will query the "domain allocation table" according to the "domain address" in the lighting script, so as to obtain the routing correspondence that the lighting script information should be transmitted.

[0037] The "domain allocation table" records the driver program object to be called for each "domain address", and the "domain address" corresponds to the lighting script data one by one. The routing allocation module queries the transmission path based on the matching of the "domain allocation table" and the "domain address", and accurately transmits the lighting script data to the corresponding LED wired driver module and wireless communication driver module to achieve wired and wireless hybrid connection.

[0038] In step 5, the LED wired driving module or the wireless communication driving module reorganizes the data frame according to the channel format to complete the protocol conversion;

[0039] The channel formats include uartONcan bus, wifi, BT3.0, BLE5.0, and different channel formats correspond to different data frame encapsulation formats;

[0040] The uartONcan bus is directly framed at the link layer, the wifi corresponds to the UDP format, the BT3.0 corresponds to the SPP protocol format, and the BLE5.0 corresponds to the GATT layer format;

[0041] The reorganized data frame encapsulates the lighting script information according to the data frame encapsulation format corresponding to the channel format.

[0042] Both the LED wired drive module and the wireless communication drive module complete protocol conversion by reorganizing data frames, coordinating the synchronous changes of lights in different channels, realizing wired and wireless hybrid connection, and solving the communication wiring convenience and cost control issues in the layout of ambient lights in the entire vehicle space.

[0043] Significant effect: The present invention provides a wired and wireless hybrid atmosphere light control system and method based on an accelerator engine. With the help of the routing scheduling design of the "atmosphere light flow accelerator engine system", the wired and wireless hybrid of the atmosphere light in the whole vehicle space is realized, which solves the communication wiring convenience and cost control problems of the atmosphere light layout in the whole vehicle space, and hides the underlying communication details, thereby greatly simplifying the difficulty of software application layer development.
