[0026] In recent years, with the rapid development of electronic information technology and the continuous transformation of the automobile manufacturing industry, the application and innovation of automotive electronic technology have greatly promoted the progress and development of the automobile industry. It improves the kinetic energy, economy, safety, convenience and comfort of automobile driving, and also enables automobiles to have rich functions such as entertainment, office and communication. At present, with the development of Internet of Vehicles technology, technology, intelligence and humanization are redefining the future of automobiles. However, if a fault occurs during the driving of the car, the left turn signal and the right turn signal flash at the same time, and the vehicle behind cannot be instructed to turn, which brings safety hazards.

[0027] Reference Figure 1 As shown, in order to solve the above technical problems, the present application provides a warning system, including a storage module 10, a display module 20, a turn signal module 30, and an operation processing module 40. The storage module 10 is used to store warning information; the display module 20 includes a warning display screen 21, which is integrated with the rear windshield of the vehicle, and the warning display screen 21 is used to display warning information; the turn signal module 30 is used to flash the left turn signal or the right turn signal for turning warning according to the turning instruction, and to flash the left turn signal and the right turn signal at the same time for crisis warning according to the crisis warning information; the operation processing module 40 is used to respond to the turning instruction in the state of crisis warning, flash one of the left turn signal and the right turn signal for turning warning, and display the warning information on the display module 20 in the state of turning warning. Thus, the turn signal lamp can provide turn warning and crisis warning at the same time. When the vehicle is in the state of crisis warning, the turn warning needs to be performed at the same time. The operation processing module 40 can make one of the left turn signal lamp and the right turn signal lamp flash to perform the turn warning, and display the warning information on the display module 20 in the state of performing the turn warning. Thus, the rear vehicle can observe the warning information of the crisis warning from the warning display screen 21 integrated in the rear windshield, and can also judge the turn warning of the front vehicle through the turn signal lamp module 30, so as to improve the driving safety performance and reduce the potential safety hazards of driving.

[0028] The storage module 10 is Universal Flash Storage (UFS), which is a flash storage specification designed for use in consumer electronic products such as digital cameras and smart phones. Its design goal is to develop a unified flash memory card format that provides high data transfer speed and stability while also reducing consumer confusion about the various memory card formats on the market and the use of different memory card adapters.

[0029] The display module 20 includes a warning display screen 21 and a central control display screen 22, wherein the warning display screen 21 is integrated on the rear windshield. The warning information that can be displayed on the warning display screen 21 includes images, texts, etc. The images of the warning information include triangular warning images, etc.; the text of the warning information includes "The vehicle in front is in a crisis state, please pay attention to the vehicles behind", etc. Either the image or the text can be selected for display according to the actual situation to remind the vehicles behind to pay attention to safety.

[0030] The turn signal module 30 includes a left turn signal and a right turn signal, and the left turn signal and the right turn signal are arranged at the rear of the vehicle body, the reflector, and the side of the vehicle body. The indication information of the turn signal can be observed from the side and the rear of the vehicle body. When the vehicle is in a crisis warning state, the left turn signal and the right turn signal can flash at the same time to warn. When the vehicle is in a turn warning, the turn warning can be achieved by flashing one of the left turn signal and the right turn signal. During the crisis warning and the turn warning, the flashing frequency of the turn signal can be adjusted to achieve a warning of the degree of crisis, that is, the higher the flashing frequency of the turn signal, the more critical the situation.

[0031] The computing processing unit is a system-on-chip (Soc for short). In addition to processing crisis warning information, Soc can also realize functions in the smart cockpit including display control, intelligent driving, and human-computer interaction.

[0032] In some embodiments, reference Figure 1As shown, after the steering command is completed, the operation processing module 40 calculates the visibility according to the weather signal and the road condition signal. If the visibility is greater than the preset visibility value, the warning information displayed on the display module 20 is cancelled. The steering command includes a left steering command and a right steering command. When the left steering command is issued, the left turn signal is driven to flash; when the right steering command is issued, the right turn signal is driven to flash. The steering command can be issued by the driver in the car and the vehicle system. When the vehicle is controlled by the driver, the general steering command is issued by the driver in the car manually turning on the turn signal switch. When the vehicle is in the intelligent driving state, the general steering command is issued by the Soc after processing the signal of the vehicle sensor. The weather signal may include signals such as clearness, ambient temperature, ambient humidity, fog concentration, etc., and the road condition signal may include flatness, road humidity, etc. These signals can affect the visibility of the vehicle, and the visibility can also be calculated by these signals. Visibility is generally reflected by the visual distance, and the preset visibility value can be set to 100m. When the visibility is greater than 100m, the visible distance is relatively large. At this time, whether warning is given through the turn signal or through the display module 20, it will not have a great impact on the safety hazard of the following vehicle. The warning information displayed on the display module 20 can be canceled to reduce the energy consumption of the vehicle.

[0033] In some embodiments, reference Figure 1 As shown, after the steering command is completed, the operation processing module 40 calculates the visibility according to the weather signal and the road condition signal. If the visibility is less than the preset visibility value, the left turn signal and the right turn signal are flashed at the same time to warn of the crisis, and the warning information is displayed on the display module 20. For example, the preset visibility value can be set to 100m. When the visibility is less than 100m, the visual distance is small. At this time, only warning through the turn signal or only warning through the display module 20 has a greater impact on the safety hazards of the following vehicles. The left turn signal and the right turn signal can be flashed at the same time to warn of the crisis, and the warning information is displayed on the display module 20 to improve the safety performance of driving and reduce the safety hazards of driving.

[0034] In some embodiments, reference Figure 1As shown, after the steering command is completed, the operation processing module 40 calculates the visibility according to the weather signal and the road condition signal. If the visibility is less than the preset visibility value, the frequency of the left turn signal and the right turn signal flashing at the same time is increased, and the warning information is adjusted from static information to dynamic information. The flashing frequency of the turn signal module 30 can be divided into multiple levels. The flashing frequency of the example can be divided into level 1, level 2 and level 3, wherein the flashing frequency of level 1 to level 3 gradually increases. Level 1 corresponds to visibility of 80m-100m, level 2 corresponds to visibility of 60m-80m, and level 3 corresponds to visibility less than 60m. That is, the lower the visibility, the higher the flashing frequency of the turn signal. At the same time, the warning information is adjusted from static information to dynamic information. It can have a better warning effect in the form of low visibility.

[0035] In some embodiments, reference Figure 1 As shown, the early warning system also includes an information collection module 50, which is used to transmit the electrical signal of the crisis alarm button 60 to the operation processing module 40. If the electrical signal of the crisis alarm button 60 received by the operation processing module 40 is a high-level signal, the crisis alarm information is output. The cockpit in the car is generally provided with a crisis alarm button 60 switch. When the crisis alarm button 60 switch on the car is pressed, the logic level is high at this time. After the Soc collects the high level, the instrument is driven to display the double flash indicator light, and the turn signal module 30 double flashes and the display module 20 displays the early warning information. In an example, a command can be sent through the controller local area network bus to notify the system to output the double flash of the turn signal module 30 to warn of the crisis.

[0036] In some embodiments, reference Figure 1 As shown, the early warning system also includes an information acquisition module 50, which is used to collect image signals and radar signals of the vehicle under various working conditions, and transmit the image signals and radar signals to the operation processing module 40, and the operation processing module 40 determines whether to output crisis warning information according to the image signals. The information acquisition module 50 also includes radar, camera, etc., and determines whether the vehicle is in a crisis state that the driver cannot detect during driving through the image signals and radar signals collected by the radar and camera. If the vehicle is in a crisis state, a high-level signal is output according to the crisis state to the Soc driving instrument to display the double flash indicator light, and the turn signal module 30 double flashes and the display module 20 displays the early warning information.

[0037] In some embodiments, the warning information includes image warning information and text warning information, and the display screen is a transparent display screen. The display screen is a transparent display screen that can partially block the driver from observing the rear of the vehicle through the rearview mirror in the driving position, so that the driver can make a judgment to avoid danger.

[0038] In some embodiments, the operation processing module 40 drives the warning display screen 21 to display warning information through a low voltage differential signal. The low voltage differential signal transmission support rate is generally above 155Mbps (approximately 77MHz). Low voltage differential signaling is a low swing differential signaling technology that enables signals to be transmitted at a rate of several hundred Mbps on a differential PCB line pair or a balanced cable. Its low voltage amplitude and low current drive output achieve low noise and low power consumption.

[0039] In some embodiments, reference Figure 1 As shown, the display module 20 also includes a central control display screen 22, and the processing module 40 displays the warning information on the warning display screen 21 and the central control display screen 22 at the same time. The central control display screen 22 can provide auxiliary reminders to the driver through image information and indicator light information, so that the driver can obtain at any time whether the turn signal module 30 is in a flashing state and whether the display module 20 displays warning information.

[0040] In the present application, the turn signal lamp can provide turn warning and crisis warning at the same time. When the vehicle is in the state of crisis warning, the turn warning needs to be performed at the same time. The operation processing module 40 can make one of the left turn signal lamp and the right turn signal lamp flash to perform the turn warning, and display the warning information on the display module 20 in the state of performing the turn warning. As a result, the rear vehicle can observe the warning information of the crisis warning from the warning display screen 21 integrated in the rear windshield, and can also judge the turn warning of the front vehicle through the turn signal lamp module 30, so as to improve the driving safety performance and reduce the potential safety hazards of driving. When the visual distance is large, whether the warning is performed through the turn signal lamp or the display module 20, it will not have a great impact on the potential safety hazards of the rear vehicle, and the warning information displayed on the display module 20 can be cancelled to reduce the energy consumption of the vehicle. When the visible distance is small, warning only through the turn signal or only through the display module 20 will have a greater impact on the safety hazards of the following vehicles. The left turn signal and the right turn signal can flash at the same time to warn of the crisis, and the warning information can be displayed on the display module 20 to improve driving safety performance and reduce driving safety hazards.

[0041] Reference Figure 2 As shown, the present application also provides an early warning method, which specifically includes the following steps:

[0042] Step S100: In response to a turn signal in a state of performing a crisis warning, one of the left turn signal and the right turn signal is flashed to perform a turn signal warning.

[0043] Step S200: extract warning information and display it on the display module 20.

[0044] Step S300: Calculate visibility based on weather signals and road condition signals. If visibility is greater than a preset visibility value, cancel the warning message displayed on the display module 20. If visibility is less than a preset visibility value, make the left turn signal and the right turn signal flash simultaneously to give a crisis warning, and display the warning message on the display module 20.

[0045] The early warning method in the present application can judge the turning warning of the front vehicle through the turn signal module 30, thereby improving the driving safety performance and reducing the potential safety hazards of driving. When the visible distance is large, whether the warning is given through the turn signal or the display module 20, it will not have a great impact on the potential safety hazards of the rear vehicle. The warning information displayed on the display module 20 can be cancelled to reduce the energy consumption of the vehicle. When the visible distance is small, at this time, only the turn signal or only the display module 20 will have a great impact on the potential safety hazards of the rear vehicle. The left turn signal and the right turn signal can be flashed at the same time for crisis warning, and the warning information will be displayed on the display module 20 to improve the driving safety performance and reduce the potential safety hazards of driving.
