Description

Technical Field

[0001] This application relates to the field of vehicle safety technology, and in particular to a safe distance reminder system, method, vehicle, and storage medium. Background Technology

[0002] Insufficient following distance is a major cause of traffic accidents. Therefore, reminding drivers to maintain a safe following distance is crucial for traffic safety.

[0003] In related technologies, safe distance warnings are typically provided through audible alarms. Many automotive safety systems use sensors such as radar and cameras to monitor vehicles and obstacles ahead. These sensors can sometimes be affected by factors such as weather and lighting, leading to inaccurate detection results. Furthermore, they are not intuitive enough and are easily overlooked. Under normal circumstances, drivers can adjust their safe distance based on radar alarm sounds or visual observation. However, in certain special situations, such as when novice drivers are using noise-canceling headphones, playing loud music and unable to hear the warnings, or inexperienced drivers in complex environments who misjudge distances, the likelihood of accidents increases significantly, necessitating improvement.

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following description, with reference to the accompanying drawings, describes a safe distance reminder system, method, vehicle, and storage medium according to embodiments of this application. Addressing the technical problems mentioned in the background art, which rely on the driver's experience and sensitivity to ambient sound, and are easily affected by environmental interference during distance measurement, thus affecting distance detection results and posing significant safety hazards, this application provides a safe distance reminder system. In this system, a light signal transmitter emits a first light signal from the vehicle itself, and a light signal receiver receives multiple second light signals emitted by other vehicles. A processing module determines the light signal parameters of the first light signal, and after receiving multiple second light signals, identifies the light signal pattern of each second light signal to determine the distance information between the vehicle and other vehicles based on the light signal pattern. Then, a reminder module provides different light reminders based on the distance. Utilizing light signal transmission and reception technology, and through vehicle-to-vehicle communication, the system monitors the distance between vehicles in real time and intuitively reminds the driver to adjust their following distance to maintain a safe driving distance, reducing the impact of the external environment on distance detection, thereby ensuring the safety of the driver and vehicle and effectively reducing the incidence of traffic accidents. This solves the technical problem that relies on the driver's experience and sensitivity to ambient sounds, and is easily affected by environmental interference during distance measurement, thus affecting the distance detection results and posing a significant safety hazard.

[0025] Specifically, Figure 1 This is a schematic diagram of a safety distance reminder system provided in an embodiment of this application.

[0026] like Figure 1 As shown, the safety distance reminder system 10 includes: a light signal transmitter 100, a light signal receiver 200, a processing module 300, and a reminder module 400.

[0027] Specifically, the optical signal transmitter 100 is used to transmit a first optical signal according to the optical signal parameters.

[0028] In actual operation, the optical signal transmitter 100 can be installed at the front of the vehicle and is responsible for transmitting the first optical signal forward. The optical signal parameters may include the generation frequency, optical signal wavelength, optical signal encoding, etc.

[0029] After the first light signal is transmitted, other vehicles can decode the received light signal, calculate the distance between the two vehicles, and thus realize communication between the vehicles.

[0030] Optionally, in one embodiment of this application, the optical signal transmitter 100 includes an encoder and a guiding unit.

[0031] The encoder is used to encode the first optical signal using a preset communication protocol and frequency selection mechanism before transmitting the first optical signal.

[0032] The guiding unit is used to limit the transmission direction of the first optical signal so that the transmission path of the first optical signal after transmission is within the current driving lane of the vehicle.

[0033] To prevent other receivers unrelated to traffic from receiving the light signal emitted by the vehicle and thus affecting its original function, the light signal transmitter 100 of this application embodiment can introduce an encoding and decoding mechanism into the light signal, ensuring that only target vehicles with the corresponding decoders can correctly receive and interpret the light signal. This encoding and decoding can be implemented using cryptographic algorithms or specific communication protocols and frequency selection mechanisms, and is processed by the processing module 300 to ensure that only the target vehicle can recognize and process the light signal. By appropriately selecting the communication protocol and frequency, the impact of the light signal on other lanes can be reduced, thereby minimizing interference.

[0034] Therefore, in the embodiments of this application, an encoder can be used to encode the first optical signal. The communication protocol and frequency selection mechanism can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here.

[0035] Furthermore, the optical signal transmitter 100 in this embodiment can also employ directional light transmission technology, using a guiding unit to restrict the transmission direction of the optical signal to the lane where the target vehicle is located. By precisely controlling the transmission path and angle of the light, interference of the optical signal to other lanes can be reduced.

[0036] The optical signal receiver 200 is used to receive multiple second optical signals emitted by vehicles other than the vehicle itself.

[0037] As one possible implementation, the optical signal receiver 200 of this application embodiment can be installed at the rear of a vehicle to receive a second optical signal emitted by other vehicles.

[0038] Optionally, in one embodiment of this application, the optical signal receiver 200 includes a decoder.

[0039] The decoder is used to decode the second optical signal using a preset communication protocol, obtain the decoding result, and delete all second optical signals that do not meet the preset special transmission conditions based on whether the decoding result and the frequency of the second optical signal meet the preset special transmission conditions.

[0040] Corresponding to the encoder, the optical signal receiver 200 in this application embodiment may include a decoder to receive a second optical signal with a specific communication protocol and frequency selection mechanism, thereby avoiding receiving irrelevant information and reducing the probability of accidental touch.

[0041] In actual implementation, the optical signal receiver 200 of this application embodiment can determine whether the received optical signal can be decoded by using a specific communication protocol and frequency selection mechanism pre-set by the decoder after receiving any optical signal. If the optical signal cannot be decoded, it does not meet the preset special transmission conditions. If the optical signal can be decoded, the next distance calculation can be performed.

[0042] It should be noted that the preset special transmission conditions can be set by the protocol between the encoder and decoder, and no specific restrictions are made here.

[0043] The processing module 300 is used to determine the optical signal parameters based on the vehicle's speed and lane change data, and after receiving multiple second optical signals, classify each second optical signal to obtain the classification result, and identify the optical signal pattern of each second optical signal according to the classification result, so as to determine the distance information between other vehicles and the vehicle based on the optical signal pattern.

[0044] The processing module 300 in this embodiment can control the transmission and reception of light signals, calculate the safe driving distance, and use algorithms to control the light source to emit different light signals according to different environments.

[0045] In some embodiments, the processing module 300 can dynamically adjust the optical signal parameters based on the vehicle's speed and lane-changing data. Specifically, it dynamically adjusts the optical signal parameters according to changes in vehicle speed and lane-changing frequency. When the vehicle is traveling at high speed, the brightness of the light source can be increased to improve signal strength and reception stability. For frequent lane changes, a higher signal frequency can be used to reduce the possibility of missed reception, thereby increasing the stability of optical signal transmission.

[0046] In other embodiments, the processing module 300 may also use machine learning algorithms to train a model to identify and distinguish the light signals of different vehicles. By training on a large amount of data, the model can learn the light signal patterns between different vehicles and provide accurate distance information based on the patterns.

[0047] Optionally, in one embodiment of this application, the processing module 300 includes: an acquisition unit, a prediction unit, and a compensation unit.

[0048] The acquisition unit is used to acquire the vehicle's historical driving data.

[0049] The prediction unit is used to predict the vehicle's speed and lane at the next moment based on historical driving data, vehicle speed, and lane change data.

[0050] The compensation unit is used to determine the optical signal parameters based on the vehicle speed and driving lane at the next moment.

[0051] In actual implementation, embodiments of this application can use prediction algorithms and compensation mechanisms to reduce the impact of vehicle speed changes and lane changes on optical signal transmission. For example, the processing module 300 can obtain the vehicle's historical driving data and behavior patterns (such as speed changes, lane changes, etc.) through the acquisition unit, and make predictions based on the historical data and behavior patterns through the prediction unit. Finally, the compensation unit adjusts the optical signal transmission parameters in advance to adapt to the upcoming speed changes or lane changes.

[0052] Optionally, in one embodiment of this application, the processing module 300 further includes an accumulation unit and a correction unit.

[0053] The cumulative unit is used to accumulate the vehicle's speed change frequency and lane switching frequency based on historical driving data.

[0054] The correction unit is used to correct the light source brightness in the optical signal parameters when the speed change frequency or lane switching frequency meets the preset signal enhancement conditions, so that the light source brightness meets the preset stable transmission conditions.

[0055] As one possible implementation, the processing module 300 in this embodiment can also perform real-time correction of the light source brightness in the optical signal parameters.

[0056] For example, the speed change frequency and lane switching frequency of the vehicle can be accumulated by the accumulation unit. When the speed change frequency or lane switching frequency meets the preset signal enhancement conditions, such as when the speed change frequency or lane switching frequency is greater than a certain value, it can be determined that the driver's driving habit is frequent speed change or frequent lane change. In order to avoid affecting the stability of signal transmission, the embodiment of this application can correct the light source brightness by the correction unit.

[0057] It should be noted that the preset signal enhancement conditions and preset stable transmission conditions can be set by those skilled in the art according to the actual situation, and no specific restrictions are imposed here. Among them, under the preset stable transmission conditions, it is necessary to ensure that the optical signal can be stably transmitted between the two vehicles.

[0058] Furthermore, to ensure the stability of optical signal transmission, embodiments of this application can also utilize multi-channel signal transmission. For example, in situations where vehicle speed changes rapidly or lane changes are frequent, multi-channel transmission technology can be considered. By transmitting optical signals simultaneously on multiple channels, signal stability and reliability can be increased. Even if the vehicle loses signal on one channel, it can still receive signals through other channels, thereby reducing the possibility of missed reception.

[0059] The reminder module 400 is used to generate a corresponding lighting control strategy based on distance information, so as to use the lighting control strategy to control the vehicle's lights.

[0060] Furthermore, the reminder module 400 can use algorithms to control the light source to emit different light signals based on distance information in different environments.

[0061] For example, when it is determined from distance information that other vehicles are within a safe distance from the vehicle, embodiments of this application may use a green light signal to convey to the driver that a good safe distance is currently being maintained.

[0062] When the distance between the vehicle and other vehicles is gradually approaching a safe distance based on distance information, this embodiment of the application can use a yellow light signal to remind the driver to slow down or remain vigilant.

[0063] When the distance information determines that other vehicles are too close to the vehicle, this embodiment of the application can use a red light signal to issue an emergency warning to the driver, requiring him to take immediate action, such as braking or swerving.

[0064] In addition to reminding the driver of the vehicle, this embodiment of the application can also remind other vehicles to maintain a safe distance by using the vehicle's lights, such as external parking lights, flashing low beam headlights, or projecting images onto the exterior of the vehicle, as the distance gradually approaches the safe distance. The safe distance can be set by those skilled in the art according to actual conditions, and no specific limitations are imposed here.

[0065] Optionally, in one embodiment of this application, the reminder module 400 includes: a calculation unit, a sorting unit, and a light control unit.

[0066] The calculation unit is used to calculate the distance and orientation between the vehicle and the driver for each second optical signal based on the distance information.

[0067] The sorting unit is used to assign hazard weights to other vehicles based on distance and orientation, obtain the assignment results, and sort the hazard levels of other vehicles based on the assignment results to obtain a hazard list.

[0068] The lighting control unit is used to generate lighting alert strategies based on a hazard list.

[0069] In actual implementation, this embodiment can determine the distance and orientation between the vehicle corresponding to each second light signal and the vehicle itself based on distance information. Then, a hazard weight is assigned through a sorting unit. For example, vehicles in the opposite lane have a lower hazard weight, while vehicles in the same lane have a higher hazard weight. The closer the vehicle, the higher the hazard weight, and the farther the vehicle, the lower the hazard weight. Based on the comprehensive assignment results, the degree of danger posed by other vehicles to the vehicle is determined and sorted to obtain a hazard list. The lighting control unit can provide corresponding lighting reminders based on the hazard list. For example, when there is a vehicle ranked high on the left, the left lights flash red; when there is a vehicle ranked in the middle on the right, the right lights flash yellow; when vehicles in front or behind are close, all lights flash, etc. The working principle of the safe distance reminder system 10 of this embodiment is explained using one example.

[0070] Furthermore, embodiments of this application may also restrict the control of the vehicle itself based on the degree of danger.

[0071] For example, when the distance between the vehicle in front and the vehicle in front is determined to be close, the accelerator pedal can be restricted to prevent the driver from accidentally pressing it and colliding with the vehicle in front; when the distance between the vehicle behind and the vehicle in front is determined to be close, the brake pedal can be restricted to prevent the driver from accidentally pressing it and colliding with the vehicle behind; when the lateral distance between the vehicle in front and the vehicle in different lanes is determined to be close, and the vehicle has no need to change lanes or turn, the steering wheel angle can be restricted to prevent the driver from accidentally pressing it and colliding with the vehicle in front.

[0072] During use, the light signal transmitter 100 can periodically emit a first light signal, and the light signal receiver 200, after receiving the second light signal, transmits the signal to the processing module 300. The processing module 300 can determine the distance between vehicles by calculating the propagation time and speed of the light signal, and according to the preset safe distance standard, control the light source display (such as LED lights) installed at the rear or top of the vehicle to emit different light signals to prompt the drivers of the following vehicles and help them maintain a safe distance from the vehicle in front.

[0073] For example, when it is determined from distance information that other vehicles are within a safe distance from the vehicle, embodiments of this application may use a green light signal to convey to the driver that a good safe distance is currently being maintained.

[0074] When the distance between the vehicle and other vehicles is gradually approaching a safe distance based on distance information, this embodiment of the application can use a yellow light signal to remind the driver to slow down or remain vigilant.

[0075] When the distance information determines that other vehicles are too close to the vehicle, this embodiment of the application can use a red light signal to issue an emergency warning to the driver, requiring him to take immediate action, such as braking or swerving.

[0076] In real-world traffic environments are complex and ever-changing. Ensuring that optical signals are transmitted only to the target vehicle and avoiding interference with vehicles in other lanes is a crucial consideration in multi-lane traffic. Based on this, embodiments of this application utilize various technical means to achieve stable optical signal transmission:

[0077] 1. Using directional light transmission technology, the transmission direction of the light signal is limited to the lane where the target vehicle is located. By precisely controlling the transmission path and angle of the light, interference of the light signal to other lanes can be reduced.

[0078] 2. Introduce encoding and decoding mechanisms into the optical signal so that only target vehicles with the corresponding decoders can correctly receive and interpret the optical signal. This encoding and decoding can be implemented using cryptographic algorithms or specific communication protocols and frequency selection mechanisms, processed by a central processing unit to ensure that only the target vehicle can recognize and process the optical signal. By appropriately selecting the communication protocol and frequency, the impact of the optical signal on other lanes can be reduced, thereby minimizing interference.

[0079] 3. Wavelength Separation: Wavelength separation of optical signals can be achieved by using different wavelengths. By using different wavelengths in different lanes, interference between lanes can be avoided. The receiver only receives the optical signal whose wavelength matches its configuration, thereby reducing the possibility of accidentally triggering receivers in other lanes.

[0080] 4. Machine learning algorithms can be used to train models to identify and differentiate the light signals of different vehicles. By training on a large amount of data, the model can learn the light signal patterns between different vehicles and provide accurate distance information based on these patterns.

[0081] Based on this, to ensure stable transmission of optical signals when the vehicle's speed changes rapidly or lane changes frequently, the embodiments of this application may also adopt the following strategies:

[0082] 1. Dynamically Adjusting Optical Signal Parameters: Based on changes in vehicle speed and lane-changing frequency, the optical signal parameters can be dynamically adjusted. When the vehicle is traveling at high speed, the brightness of the light source can be increased to improve signal strength and reception stability. For situations involving frequent lane changes, a higher signal frequency can be used to reduce the possibility of missed reception.

[0083] 2. Multi-channel transmission: When the vehicle's speed changes rapidly or lane changes frequently, multi-channel transmission technology can be considered. By transmitting optical signals simultaneously on multiple channels, signal stability and reliability can be increased. Even if the vehicle loses signal on one channel, it can still receive signals through other channels, thus reducing the possibility of missed reception.

[0084] 3. Prediction and Compensation: Prediction algorithms and compensation mechanisms can reduce the impact of vehicle speed changes and lane changes on optical signal transmission. System 10 can make predictions based on historical data and vehicle behavior patterns, and adjust the transmission parameters of the optical signal in advance to adapt to upcoming speed changes or lane changes.

[0085] In large-scale traffic environments, the optical signals of each vehicle form an optical signal network. Vehicle-to-everything (V2X) and artificial intelligence (AI) can be used to optimize the adaptability and anti-interference capabilities of this network. AI technology can be used to develop intelligent adaptive control algorithms to adjust the timing and phase of optical signals to adapt to different environmental changes. System 10 can use algorithms to dynamically adjust based on current lighting conditions and traffic environment. This can include automatically adjusting the brightness of the light source or the frequency of optical signal transmission, ensuring accurate cues under various conditions. For example, at night or in poor lighting conditions, a stronger light source can be used to increase the transmission intensity of the optical signal. Utilizing V2X information sharing, by monitoring changes in optical signals around the vehicle in real time, System 10 can issue warnings or provide prompts to help drivers take appropriate actions and avoid potential accidents. Simultaneously, System 10 can also achieve intelligent fault detection and management of optical signal equipment. By monitoring equipment status in real time, collecting fault data, and applying machine learning algorithms for analysis, early warning and automatic diagnosis of faults can be achieved.

[0086] Compared with the notification methods of related technologies, the embodiments of this application also have the following advantages:

[0087] First, the light signal-based system 10 can use different light signal patterns to prompt the driver, such as flashing, changing colors, or intensities. Compared to sound or vibration, diverse light signal patterns are more intuitive and reliable, attracting the driver's attention more strongly, creating a stronger visual impact, and are less likely to be ignored.

[0088] Secondly, light signals travel at high speeds. By utilizing light signal transmission and reception technology, more accurate distance calculation results can be provided, enabling real-time monitoring of distances and speeds between vehicles and improving the accuracy and timeliness of alerts.

[0089] Finally, the light signals emitted by the light signal transmitter can maintain clear visibility under different weather and lighting conditions, making them more widely applicable.

[0090] The embodiments of this application can help drivers maintain a safe driving distance more intuitively, effectively reducing the incidence of traffic accidents and playing an important role in improving traffic safety. Furthermore, the system 10 of this application embodiment can be adjusted and improved according to specific requirements to adapt to different types and brands of vehicles, thus having a wider range of applications.

[0091] The safe distance reminder system proposed in this application can utilize a light signal transmitter to transmit a first light signal from the vehicle itself, and a light signal receiver to receive multiple second light signals emitted by other vehicles. A processing module determines the light signal parameters of the first light signal, and after receiving multiple second light signals, identifies the light signal pattern of each second light signal to determine the distance information between the vehicle and other vehicles based on the light signal pattern. Then, a reminder module provides different light reminders based on the distance. Utilizing light signal transmission and reception technology, and through vehicle-to-vehicle communication, the system monitors the distance between vehicles in real time and intuitively reminds the driver to adjust their following distance to maintain a safe driving distance, reducing the impact of the external environment on distance detection, thereby ensuring the safety of the driver and vehicle and effectively reducing the incidence of traffic accidents. This solves the technical problem in related technologies that rely on the driver's experience and sensitivity to ambient sound, and are easily affected by environmental interference during distance measurement, thus affecting the distance detection results and posing significant safety hazards.

[0092] Next, the method for reminding of safe distances according to the embodiments of this application is described with reference to the accompanying drawings.

[0093] Figure 2 This is a flowchart of a method for reminding people of safe distance according to an embodiment of this application.

[0094] like Figure 2As shown, this method for reminding people of safe distances is applied during the signal transmission phase, and the method includes the following steps:

[0095] In step S201, the vehicle speed and lane change data are obtained.

[0096] In step S202, the vehicle's optical signal parameters are determined based on vehicle speed and lane change data.

[0097] In step S203, a first optical signal is transmitted based on optical signal parameters so that other vehicles besides the vehicle can determine the distance information between the vehicle and other vehicles after receiving the first optical signal.

[0098] It should be noted that the explanation of the above-mentioned embodiment of the safety distance reminder system also applies to the safety distance reminder method of this embodiment, and will not be repeated here.

[0099] The safe distance reminder method proposed in this application utilizes a light signal transmitter to transmit a first light signal from the vehicle itself, and a light signal receiver to receive multiple second light signals emitted by other vehicles. A processing module determines the light signal parameters of the first light signal, and upon receiving multiple second light signals, identifies the light signal pattern of each second light signal to determine the distance information between the vehicle and other vehicles based on the light signal pattern. Then, a reminder module provides different light reminders based on the distance. By utilizing light signal transmission and reception technology and through vehicle-to-vehicle communication, the distance between vehicles is monitored in real time, and the driver is intuitively reminded to adjust their following distance to maintain a safe driving distance through light signals. This reduces the impact of the external environment on distance detection, thereby ensuring the safety of the driver and vehicle and effectively reducing the incidence of traffic accidents. This solves the technical problem in related technologies that rely on the driver's experience and sensitivity to ambient sound, and are easily affected by environmental interference during distance measurement, thus affecting the distance detection results and posing significant safety hazards.

[0100] The method for reminding of safe distances according to embodiments of this application is described again with reference to the accompanying drawings.

[0101] Figure 3 This is a flowchart of a method for reminding people of safe distance according to an embodiment of this application.

[0102] like Figure 3 As shown, this method for reminding of safe distances is applied during the signal reception phase, and the method includes the following steps:

[0103] In step S301, multiple second optical signals emitted by other vehicles besides the vehicle itself are received.

[0104] In step S302, each second optical signal is classified to obtain a classification result, and the optical signal pattern of each second optical signal is identified according to the classification result, so as to determine the distance information between other vehicles and the vehicle based on the optical signal pattern.

[0105] In step S303, a corresponding lighting control strategy is generated based on the distance information, so as to use the lighting control strategy to control the vehicle's lighting.

[0106] It should be noted that the explanation of the above-mentioned embodiment of the safety distance reminder system also applies to the safety distance reminder method of this embodiment, and will not be repeated here.

[0107] The safe distance reminder method proposed in this application utilizes a light signal transmitter to transmit a first light signal from the vehicle itself, and a light signal receiver to receive multiple second light signals emitted by other vehicles. A processing module determines the light signal parameters of the first light signal, and upon receiving multiple second light signals, identifies the light signal pattern of each second light signal to determine the distance information between the vehicle and other vehicles based on the light signal pattern. Then, a reminder module provides different light reminders based on the distance. By utilizing light signal transmission and reception technology and through vehicle-to-vehicle communication, the distance between vehicles is monitored in real time, and the driver is intuitively reminded to adjust their following distance to maintain a safe driving distance through light signals. This reduces the impact of the external environment on distance detection, thereby ensuring the safety of the driver and vehicle and effectively reducing the incidence of traffic accidents.
