Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] Reference Figure 1 , Figure 1 This is a structural block diagram of the first embodiment of the vehicle light strip control system of the present invention.

[0047] like Figure 1 As shown, the vehicle-mounted light strip control system of this embodiment includes: the vehicle-mounted light strip control system includes: a vehicle-mounted control module 100, a light strip control module 200 and several street light strips 300; wherein, the vehicle control module 100 is connected to the light strip control module 200, and the light strip control module 200 is connected to the several street light strips 300.

[0048] It should be noted that the vehicle light strip control system involved in this embodiment can be a vehicle light strip control device with data processing and network communication functions, or other vehicle light strip control systems that can achieve the same or similar functions and include the vehicle light strip control device.

[0049] The vehicle control module 100 is used to generate a vehicle control instruction according to the operating state of the vehicle and send the vehicle control instruction to the light strip control module 200.

[0050] It should be understood that the above-mentioned vehicle control module 100 can be an STM32H7 microcontroller or other microcontrollers with the same or similar functions as the STM32H7 microcontroller, and this embodiment does not limit this.

[0051] It can be understood that the above-mentioned running state of the vehicle can be state information of the vehicle during operation, such as: moving forward and straight, turning and moving straight, and automatic running state.

[0052] It is understood that the above-mentioned vehicle control instructions can be instructions for controlling vehicle movement and adjusting the color display effect of the light strip. For example, when it is detected that the vehicle needs to make a steering wheel movement, the vehicle control instruction can be sent to the component in the vehicle that controls the steering wheel movement and the component that controls the color display of the light strip. After receiving the instruction, the component that controls the steering wheel movement can obtain the corresponding speed, direction and other information from the vehicle control instruction to control the steering wheel movement. At the same time, the component that controls the color display of the light strip can obtain the corresponding color, status and other information of the light strip from the vehicle control instruction to control the color display of the light strip.

[0053] In a specific implementation, a mapping relationship can be established based on all possible operating states of the vehicle and the corresponding color rendering effects of the light strip, and the established mapping relationship can be stored in the on-board control module 100. When the vehicle is running, the on-board control module 100 can obtain the current operating state of the vehicle in real time. When it is detected that the current operating state of the vehicle has changed or the vehicle has a malfunction, etc., the color rendering effect of the light strip corresponding to the current operating state of the vehicle can be searched in the pre-set mapping relationship, and a vehicle control instruction can be generated based on the current operating state of the vehicle and the corresponding color rendering effect of the light strip. When it is detected that the vehicle is running automatically, the generated vehicle control instruction can also include information such as the speed and direction of the vehicle's automatic movement.

[0054] Furthermore, in order to utilize the color rendering effect of the light strip to show the operating status of the vehicle when it is in automatic operation, the vehicle-mounted light strip control system also includes: a scheduling module 101, which is connected to the vehicle-mounted control module 100; the scheduling module 101 is used to generate corresponding scheduling instructions according to the operating status of the vehicle, and send the scheduling instructions to the vehicle-mounted control module 100; the vehicle-mounted control module 100 is used to generate vehicle control instructions according to the scheduling instructions, and send the vehicle control instructions to the light strip control module 200 through a preset communication method.

[0055] It should be noted that the above-mentioned dispatching instruction is an instruction for dispatching and controlling the current running state of the vehicle when the vehicle is in an automatic running state. The dispatching module 101 can send a dispatching instruction to the vehicle control module 100 when the vehicle is in an automatic running state, for example, when the vehicle is steering or fork arm is moving.

[0056] In a specific implementation, if the scheduling module 101 detects that the vehicle is undergoing automatic scheduling, the scheduling module 101 can send a scheduling instruction to the on-board control module 100 through a data transmission method based on the wireless TCP / IP protocol, so that the on-board control module 100 can control the corresponding components to move according to the action to be performed by the vehicle in the scheduling instruction. For example: if it is detected that the vehicle is to perform a steering wheel action, a scheduling instruction to adjust the steering wheel movement is sent to the on-board control module 100. At this time, the on-board control module 100 can generate a vehicle control instruction and synchronize the control instruction to the component that controls the steering wheel movement through the CAN bus, so that the component that controls the steering wheel movement moves according to the information contained in the control instruction.

[0057] It should be understood that the scheduling module 101 may send the scheduling instructions to the vehicle control module 100 by wirelessly transmitting data via TCP / IP.

[0058] It is understandable that the above-mentioned preset communication mode can be CAN bus communication, RS232 serial communication, RS485 serial communication, etc., and can be set according to the vehicle's operating environment or operating cost in specific implementation. This embodiment does not limit this.

[0059] The light strip control module 200 is used to determine the color rendering effect corresponding to each street light strip 300 according to the vehicle control instruction.

[0060] It should be noted that the above-mentioned light strips may be light strips pre-installed around the vehicle, for example, one light strip is provided on the left and right sides below the vehicle body and one light strip is provided above the vehicle body.

[0061] It should be understood that the above-mentioned color rendering effect can be the state of the light strip and the displayed color. The light strip can achieve four states, such as: always on, flashing, breathing light and flowing light. The color displayed by the light strip can be red, green, yellow, blue and purple, etc.

[0062] It is understandable that different light strip color effects can be set for different movement states of the vehicle. For example, when the vehicle is running automatically, all three light strips in the vehicle are green and always on. When the vehicle's fork arm moves, the light strip above the vehicle displays a flowing light color according to the up and down movement of the fork arm. When the vehicle is stopped, the red light is always on. When the vehicle has a malfunction, the yellow light is always on. When the vehicle is turning left or right, the corresponding light strip in the same direction below the vehicle displays a flowing light color in the direction of the turn, and the other two light strips display green and always on, etc. By setting different color effects for different vehicle operation states, pedestrians and drivers can intuitively obtain the current operation state of the vehicle and perform corresponding operations based on the current operation state of the vehicle. For example, when the vehicle is running automatically, pedestrians can be reminded to avoid; when the vehicle has a malfunction, the driver can be reminded to make timely repairs, making the traffic environment safer.

[0063] The light strip control module 200 is further configured to control each light strip to display colors according to its corresponding color rendering effect.

[0064] It should be understood that the light strip control module 200 can obtain the status and corresponding color of each light strip from the vehicle control instruction, and then control the corresponding light strip to display color according to the status and color.

[0065] In a specific implementation, when the vehicle is in operation, the on-board control module 100 performs real-time detection of the current operation state of the vehicle. When it is detected that the current operation state of the vehicle has changed, for example, the vehicle switches from a straight-ahead state to a left-turning state, the on-board control module 100 searches for the corresponding light strip coloring effect when the vehicle is in a left-turning state in a preset mapping relationship according to the current operation state of the vehicle. When searching for the coloring effect of the light strip when turning left, the light strip on the left side below the vehicle body is displayed as yellow in the form of a flowing light, and the flowing lights on other roads are normally displayed as green and are always on. A vehicle control instruction is generated, and then the vehicle control instruction is sent to the light strip control module 200 via CAN bus communication. After receiving the vehicle control instruction, the light strip control module 200 can obtain the current coloring effect of the light strip from the vehicle control instruction, and control the light strip on the left side below the vehicle body to be displayed as yellow in the form of a flowing light, and the flowing lights on other roads are normally displayed as green and are always on, thereby realizing the control of the coloring of the light strips of each road of the vehicle through the light strip control module 200.

[0066] It is understood that the scheduling module 101, the vehicle control module 100, and each street light strip 300 are cascaded via a serial communication interface, and data reception and decoding can be completed via a single signal line. Therefore, in order to reduce communication costs, the scheduling module 101, the vehicle control module 100, the light strip control module 200, and each street light strip 300 are cascaded via a serial communication interface.

[0067] The vehicle-mounted light strip control system of this embodiment includes a vehicle-mounted control module, a light strip control module and several street light strips; the vehicle-mounted control module generates a vehicle control instruction according to the operating status of the vehicle, and sends the vehicle control instruction to the light strip control module; the light strip control module determines the color rendering effect corresponding to each street light strip according to the vehicle control instruction; the light strip control module controls each street light strip to display color according to its corresponding color rendering effect; compared with the prior art in which one light strip controller can only control one light strip for color rendering and the color rendering effect is single, since this embodiment can generate a vehicle control instruction according to the operating status of the vehicle, and then determine the color rendering effect of each street light strip through the vehicle control instruction and display color through its corresponding color rendering effect, it solves the technical problem in the prior art that one light strip controller can only control one light strip for color rendering, thereby reducing the cost of controlling the light strip for color rendering and enriching the color rendering effect of the light strip. At the same time, by acquiring the vehicle's operating status and controlling the light strip's color display accordingly, manual switching of the light strip's color and state can be avoided, preventing traffic accidents caused by drivers forgetting to switch the light strip's color display or switching the wrong color, thereby improving road safety. Furthermore, the on-board control module, light strip control module, and individual light strips are cascaded via a serial communication interface, saving communication costs.

[0068] refer to Figure 2 , Figure 2 FIG2 is a structural block diagram of a second embodiment of a vehicle light strip control system according to the present invention. Based on the first embodiment described above, a second embodiment of a vehicle light strip control system according to the present invention is proposed.

[0069] In the second embodiment, the vehicle-mounted light strip control system also includes: a vehicle motion control module 400, and the light strip control module 200 includes: a light strip controller 201 and a CAN communication module 202; wherein, the vehicle motion control module 400 is connected to the vehicle-mounted control module 100, the CAN communication module 202 is arranged inside the light strip controller 201, and the light strip controller 201 is connected to each of the street light strips 300.

[0070] The vehicle control module 100 is further configured to receive the vehicle control instruction and generate a color control instruction and a vehicle motion control instruction based on the vehicle control instruction.

[0071] It should be noted that the above-mentioned vehicle control instructions can be instructions given to the vehicle control module 100 by the vehicle control module 100 through wired TCP / IP data transmission, thereby reducing the impact of distance and electromagnetic waves on the control effect of the vehicle control module 100, making the control effect of the vehicle control module 100 more stable.

[0072] It should be understood that the above-mentioned color control instructions may be instructions for controlling the color display effect of the light strip issued by the vehicle control module 100 to the light strip controller 201, for example: controlling the light strip to display red and always on, controlling the light strip to display in the manner of a flowing light and display green, controlling the light strip to display yellow and flashing, etc.

[0073] It can be understood that the above-mentioned vehicle motion control instructions can be instructions issued by the on-board control module 100 to the vehicle motion control module 400 to control the vehicle to operate automatically, for example: instructions to control the steering wheel or fork arm or the steering wheel and fork arm of the vehicle to move simultaneously.

[0074] In a specific implementation, the vehicle control module 100 can transmit the data in the above-mentioned vehicle control instructions through a wired TCP / IP protocol data transmission method, wherein the data for controlling the vehicle action is transmitted to the vehicle action control module 400 by generating a vehicle action control instruction, and the data for controlling the color display effect of the light strip is transmitted to the light strip controller 201 by generating a color control instruction.

[0075] The light strip controller 201 is configured to receive the color control instruction via the CAN communication module 202 and control the color rendering effect of each light strip according to the color control instruction.

[0076] It should be noted that the light strip controller 201 may be an STM32F103 single chip microcomputer or other single chip microcomputers that can realize the same functions as the STM32F103 single chip microcomputer.

[0077] It should be understood that the above-mentioned CAN communication module 202 can be a module for realizing data interaction between the light strip controller 201 and the vehicle control module 100. The CAN communication module 202 can be a TJS1051 chip or other chips with the same or similar functions as the TJS1051 chip. This embodiment does not limit this.

[0078] The vehicle motion control module 400 is used to control the vehicle to move according to the vehicle motion control instruction, so that the vehicle corresponds to the color rendering effect of each street light strip when moving.

[0079] It should be understood that the vehicle motion control module 400 may be a module for controlling components such as a steering wheel or a fork arm of the vehicle to perform related actions.

[0080] In the specific implementation, the vehicle control module 100 transmits the data in the vehicle control instructions to the vehicle motion control module 400 and the light strip controller 201 through the wired TCP / IP protocol, thereby controlling the automatic movement of the steering wheel or fork arm in the vehicle, and at the same time, each light strip displays the corresponding color according to the ongoing movement of the vehicle.

[0081] Furthermore, in order to obtain the corresponding color rendering effect of the light strip through the data sent from the vehicle-mounted control module 100, the light strip controller 201 is also used to receive the message data sent by the vehicle-mounted control module 100 through a preset communication method; the light strip controller 201 is also used to parse the message data according to a preset parsing protocol to obtain the target color effect corresponding to each street light strip after parsing; the light strip controller 201 is also used to obtain corresponding color control data according to the target color effect, and send the color control data to the corresponding street light strips.

[0082] It should be noted that the above-mentioned preset communication mode may be a CAN bus communication mode, and the data sent by the vehicle control module 100 via the CAN bus communication mode and received by the light strip controller 201 may be CAN message data.

[0083] It should be understood that the preset parsing protocol can be the application layer protocol CANopen. CANopen consists of a series of sub-protocols, including communication sub-protocols and device sub-protocols. Communication sub-protocols, such as the CIA 301 sub-protocol, regulate the architecture of the CANopen network and define corresponding functions for data objects in certain object dictionaries. The device sub-protocol can use the CIA 402 device sub-protocol, which defines data objects, state mechanisms, and control modes related to motor control. The light strip controller 201 can parse CAN message data via CANopen to obtain the color effect required by the light strip.

[0084] It is understandable that the color control data may be a 24-bit color control word for controlling the color of the light strip. After the light strip controller 201 writes the color control word into the light strip, the light strip may display the color corresponding to the color control word after power-on.

[0085] Furthermore, in order to achieve stable transmission of color control data, the light strip controller 201 is also used to simulate the target color effect through PWM control to obtain corresponding color control data; the light strip controller 201 is also used to transmit the color control data to each light strip through DMA data transmission.

[0086] It should be noted that the above-mentioned PWM control method is a pulse width modulation control method. Through the PWM control method, a PWM control signal with a certain effective duty cycle can be simulated, which presents a high-level state during the effective duty cycle time and a low-level state during the invalid duty cycle time. Among them, the high level is represented by the binary code '1' and the zero level is represented by the binary code '0', thereby combining the high and low levels into a 24-bit color control word.

[0087] It should be understood that the above-mentioned DMA data transmission method can be a method of transmitting color control data to the light strip through a DMA peripheral. In actual applications, there are two DMA controllers in the vehicle control module 100, DMA1 has 7 channels, and DMA2 has 5 channels. Each channel can receive peripheral access requests to the memory, so the light strips in the vehicle can be connected to the corresponding DMA channel, so that the color control data can be stably transmitted to each light strip through the DMA channel.

[0088] This embodiment generates corresponding color control instructions and vehicle motion control instructions based on vehicle control instructions, controls the color rendering of each street light strip according to the color control instructions, and controls vehicle motion according to the vehicle motion control instructions, so that the vehicle motion corresponds to the color rendering of each street light strip. This allows the vehicle's operating status to be better represented through the color rendering of the light strip, enriching the vehicle's color rendering effect. At the same time, color control data is controlled through PWM control and transmitted to each street light strip via DMA data transmission. This allows the light strip controller to transmit color data stably, ensuring the color rendering effect of the light strip and making the color rendering of the light strip more accurate.

[0089] refer to Figure 3 , Figure 3 FIG3 is a structural block diagram of a third embodiment of a vehicle light strip control system according to the present invention. Based on the above embodiments, a third embodiment of a vehicle light strip control system according to the present invention is proposed.

[0090] In the third embodiment, each street light strip includes: a plurality of light-emitting components, each light-emitting component includes an RGB three-color lamp 300 ′, and the RGB three-color lamp 300 ′ includes a lamp bead 301 and a color control chip 302 , and the color control chip 302 is built into the lamp bead 301 .

[0091] The color control chip 302 is used to determine whether the color control data sent by the light strip controller 201 is received when detecting that the power is turned on.

[0092] It should be noted that the color control chip 302 may be a WS2812 chip, or other chips having the same or similar functions as the WS2812 chip, and this embodiment does not impose any limitation thereto.

[0093] The color control chip 302 is further configured to, if yes, execute the operation of lighting up the lamp bead 301 according to the color control data.

[0094] It should be understood that the three colors in the RGB tri-color lamp 300' are composed of 24-bit binary codes, with each 8-bit controlling a color, ranging from 0x00 to 0xFF. To illuminate a lamp, the 24-bit color control data must be written into the registers of the WS2812 chip. After writing the color control data into the registers of the WS2812 chip, the lamps in each streetlight strip are powered on. Lamp beads corresponding to registers that have received the color control data will illuminate and display the color corresponding to the color control data. Lamp beads corresponding to registers that have not received the color control data will remain inactive.

[0095] This embodiment determines whether the color control chip has received the color control data sent by the light strip controller, and lights up the lamp beads that have received the color control data, so that the lamp beads can be lit and displayed according to the color corresponding to the color control data, thereby enriching the display effect of each light strip.

[0096] Based on the above embodiments of the vehicle light strip control system, a first embodiment of a vehicle light strip control method based on the vehicle light strip control system of the present invention is proposed.

[0097] refer to Figure 4 , Figure 4 4 is a flow chart of a first embodiment of a vehicle light strip control method according to the present invention based on the above-mentioned vehicle light strip control system.

[0098] In this embodiment, the vehicle light strip control method based on the above-mentioned vehicle light strip control system includes the following steps:

[0099] Step S10: When it is detected that the vehicle is powered on, the current vehicle operating state of the vehicle is obtained.

[0100] It should be noted that the above-mentioned vehicle operation status may be status information of the vehicle during operation, such as: moving forward and straight, turning and moving straight, and automatic operation status.

[0101] Step S20: obtaining color rendering effects corresponding to a plurality of street light strips of the vehicle based on the operating state of the vehicle.

[0102] It should be understood that the above-mentioned color rendering effect can be the state of the light strip and the displayed color. The light strip can achieve four states, such as: always on, flashing, breathing light and flowing light. The color displayed by the light strip can be red, green, yellow, blue and purple, etc.

[0103] Step S30: controlling the target light strip controller in the vehicle to display the colors of the light strips according to the color display effect.

[0104] It is understandable that the target light strip controller may be a single chip microcomputer in a vehicle system that can control the color display of each light strip in the vehicle, such as an STM32F103 single chip microcomputer.

[0105] In the specific implementation, when the vehicle is powered on, the current operating status of the vehicle is obtained. For example, if the vehicle is currently in a straight-ahead state, the color rendering effect corresponding to the straight-ahead state light strip can be found in the preset mapping relationship. If the color rendering effect corresponding to the light strip at this time is found to be that each street light strip displays a green light and is always on, the target controller can control each street light strip to display color according to the found color rendering effect.

[0106] Furthermore, in order to make the light strips display corresponding colors when the vehicle is moving automatically, the above-mentioned vehicle operating state includes an automatic scheduling state. After the above-mentioned step S30, the method also includes: when it is detected that the vehicle operating state is an automatic scheduling state, generating a corresponding vehicle control signal; controlling the vehicle to move according to the vehicle control signal, and controlling the various street light strips to display colors according to the color display effect, so that the ongoing movement of the vehicle corresponds to the color display effect of each street light strip.

[0107] This embodiment obtains the corresponding color rendering effect of the light strips based on the vehicle's current operating status when the vehicle is powered on, and controls each light strip controller to display the color corresponding to the current operating status. This allows a single light strip controller in the vehicle to control the color rendering of multiple light strips, and automatically switches to the corresponding color rendering effect based on the vehicle's operating status, thereby improving the user experience. Furthermore, when the vehicle is automatically dispatched, the color rendering effect of the light strips can also correspond to the vehicle's ongoing movement, which can better reflect the vehicle's automatic operating status.
