Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent driving technology, and in particular to a variable lane vehicle alert method, system, electronic device, and computer-readable medium. Background Technology
[0002] Reversible lanes are traffic facilities designed to alleviate traffic congestion by flexibly adjusting lane directions based on changes in traffic flow. Drivers primarily observe road signs, zigzag-shaped reversible lane information, and traffic light information.
[0003] Patent CN118506599A discloses a method for providing reversible lane direction information to vehicles passing through a reversible lane area. When the road area includes both the solid line portion and the stop line portion of the reversible lane, a reversible lane prompt is sent to vehicles within a preset range based on the lane's restriction conditions. However, only vehicles already traveling within the reversible lane can receive this prompt. If the reversible lane is prohibited, the vehicle will not be correctly prompted with the reversible lane direction information; furthermore, if the vehicle in front is driving incorrectly, it may mislead the driver, and if the driver has not paid attention to traffic signs, they may also doubt the prompt information.
[0004] Patent CN116279567 discloses a method for displaying variable lane information. The method includes: acquiring lane information of the variable lane when there is one at the intersection ahead of the vehicle; determining whether the distance between the vehicle and the intersection ahead or behind meets a trigger condition; and displaying the lane information when the distance meets the trigger condition. If the vehicle ahead is driving incorrectly, it may mislead the driver, and if the driver has not looked at traffic signs, they may also doubt the provided information. Summary of the Invention
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a variable lane vehicle reminder method and method.
[0006] In a first aspect, embodiments of the present invention provide a variable lane vehicle alert method, comprising:
[0007] When a reversible lane appears in front of the vehicle, remind the driver to check the lane sign ahead;
[0008] When a vehicle ahead makes a wrong turn, determine whether the driver has checked the signs ahead;
[0009] When the driver has checked the sign ahead, the vehicle will alert the vehicles behind it to the wrong course of traffic; if the driver has not checked the sign ahead, the vehicle will alert both itself and the vehicles behind it to the wrong course of traffic.
[0010] In some embodiments, when a reversible lane appears ahead of the vehicle, the driver is prompted to look at the lane indicator sign ahead, including:
[0011] When the distance to the sign ahead is greater than the current vehicle speed at the moment the driver first checks it, the minimum visible distance of the sign is D_min, where D_min=VT, where: V is the current vehicle speed, and T is the time required for the driver to recognize and understand the sign;
[0012] Starting from the moment the vehicle reminds the driver to check the road sign ahead, observe the driver's line of sight. The time T during which the driver's gaze lingers on the direction of the road sign ahead is recorded. 累积 = Greater than the first preset time; T 累积 = The first preset time is 1.5-2 seconds, T 累积 To accumulate eye contact time, T i Let be the time spent looking at a certain point for the i-th time, and n be the number of times the object is looked at.
[0013] In some embodiments, the first preset time is adjusted according to environmental conditions, and the first preset time corresponds to weather visibility, and the first preset time is increased as weather visibility decreases.
[0014] In some embodiments, when a jagged lane line appears ahead, it is determined that the lane ahead is a reversible lane.
[0015] In some embodiments, the erroneous driving includes:
[0016] When turning is prohibited in this lane, the vehicle in front uses its turn signal; or
[0017] When this lane prohibits straight-through or passage, the vehicle in front may proceed straight through.
[0018] In some embodiments, the step of alerting following vehicles to the wrong course of traffic when the driver has viewed the signpost ahead, and alerting both the driver and following vehicles to the wrong course of traffic when the driver has not viewed the signpost ahead, includes:
[0019] When turning is prohibited in a reversible lane, if the vehicle in front signals and the driver has checked the lane sign, the vehicle in front will not be alerted to the wrong driving; if the driver has not checked the lane sign, the vehicle in front will be alerted to the wrong driving via voice.
[0020] When straight-ahead driving or passage is prohibited in this lane, and the vehicle in front is driving straight through, the vehicle will automatically turn on its turn signal in advance to determine the turning position. If the driver has checked the lane sign, the vehicle will not be notified that the vehicle in front is driving incorrectly; if the driver has not checked the lane sign, the vehicle will be given a voice reminder that the vehicle in front is driving incorrectly.
[0021] In some embodiments, the following steps are also included:
[0022] When straight-ahead travel or passage is prohibited in this lane, the vehicle will automatically activate the turn signal in advance, based on the anticipated turning position.
[0023] When the reversible lane is closed to traffic, the turn signal will automatically activate at a preset distance from the starting point of the reversible lane on the dashed road.
[0024] When a reversible lane prohibits straight travel, the turn signal will automatically activate at a preset distance before the end of the reversible lane.
[0025] In a second aspect, the present invention provides a variable lane vehicle alert system configured to implement the above-described method, comprising:
[0026] The judgment unit prompts the driver to check the lane sign ahead when a reversible lane appears in front of the vehicle; and determines whether the driver has checked the lane sign ahead when a vehicle in front of the vehicle is driving incorrectly.
[0027] The reminder unit alerts vehicles behind it when the driver has checked the sign ahead; if the driver has not checked the sign ahead, it alerts both the vehicle behind it and vehicles behind it when the vehicle ahead is driving incorrectly.
[0028] Thirdly, the present invention also provides an electronic device, comprising:
[0029] One or more processors;
[0030] Memory, used to store one or more programs;
[0031] When the one or more programs are executed by the one or more processors, the one or more processors implement any of the methods.
[0032] Thirdly, the present invention also provides a computer-readable medium on which a computer program is stored, wherein the computer program, when executed by a processor, implements the steps in any of the methods described.
[0033] The variable lane vehicle alert method provided by this invention activates a voice prompt to the driver to check the lane sign ahead when a variable lane appears within a specific distance in front of the vehicle. If the driver has checked the lane sign and the vehicle in front is not driving according to regulations, the method does not alert the vehicle in front to its own lane, but alerts the vehicles behind it. If the driver has not checked the lane sign and the vehicle in front is not driving according to regulations, the method alerts both the vehicle in front and the vehicles behind it to the incorrect driving situation. This variable lane vehicle alert method can provide warnings to following vehicles based on the current road conditions in different variable lane scenarios, promptly reminding both the vehicle in front and the vehicles behind it not to follow the incorrect driving of the vehicle in front, thus avoiding being misled and incurring fines, and improving driving safety.

Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.
[0039] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.
[0040] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.
[0041] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.
[0042] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.
[0043] In the technical solution of this invention, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information all comply with relevant laws and regulations and do not violate public order and good morals. The use of user data in this technical solution follows relevant national laws and regulations (e.g., the "Information Security Technology - Personal Information Security Specification"). For example: appropriate measures are taken for personal information access control; restrictions are imposed on the display of personal information; the purpose of using personal information does not exceed the scope of direct or reasonable association; and explicit identity targeting is eliminated when using personal information to avoid precisely locating a specific individual.
[0044] In related technologies, if the vehicle in front is driving incorrectly, it may mislead the driver, and if the driver does not look at the traffic signs, the driver may also doubt the warning information.
[0045] To address at least one of the technical problems existing in the aforementioned related technologies, the present invention provides a variable lane vehicle alert method. Figure 1 This is a schematic diagram of a variable lane vehicle alert method provided in an embodiment of the present invention.
[0046] like Figure 1 As shown, the variable lane vehicle alert method includes the following steps:
[0047] Step S10: When a reversible lane appears in front of the vehicle, remind the driver to check the lane sign ahead.
[0048] In some embodiments, when a variable lane zigzag lane line appears within a certain distance in front of the vehicle, a voice prompt is activated to remind the driver to check the lane sign ahead.
[0049] It's understandable that reversible lanes are primarily designed for road sections where traffic is concentrated during peak hours but there are insufficient lanes, or where there are significant differences in traffic volume between morning and evening peak hours. Based on the characteristics of vehicle flow at different times, the direction of traffic is flexibly adjusted, changing the direction of travel in lanes to alleviate traffic congestion.
[0050] Step S20: When a vehicle ahead makes a mistake, determine whether the driver has checked the sign ahead.
[0051] In this embodiment, it is necessary to first confirm whether the vehicle ahead is driving incorrectly. Incorrect driving includes:
[0052] When turning is prohibited in this lane, the vehicle in front should use its turn signal.
[0053] When this lane prohibits straight-through or is closed to traffic, and the vehicle in front proceeds straight through;
[0054] If any of the above conditions are met, it means that the vehicle in front is driving incorrectly.
[0055] Furthermore, if it is determined that the vehicle ahead is driving incorrectly, it will continue to determine whether the driver has checked the sign ahead.
[0056] Specifically, when the driver first checks the sign and the distance to the sign ahead is greater than the current vehicle speed, the minimum visible distance of the sign is D_min, where D_min = VT, and V is the current vehicle speed, and T is the time required for the driver to recognize and understand the sign. The time required for the driver to recognize and understand the sign is typically 1.5-2 seconds.
[0057] Starting from the moment the vehicle reminds the driver to check the road sign ahead, observe the driver's line of sight. The time T during which the driver's gaze lingers on the direction of the road sign ahead is recorded. 累积 = Greater than the first preset time; T 累积 = The first preset time is 1.5-2 seconds, T 累积 To accumulate eye contact time, T i Let be the time spent looking at a certain point for the i-th time, and n be the number of times the object is looked at.
[0058] Step S30: If the driver has checked the sign ahead, the vehicle will only alert the vehicles behind it to the wrong direction; if the driver has not checked the sign ahead, the vehicle will alert both itself and the vehicles behind it to the wrong direction.
[0059] Please see Figure 2 When it is determined that the vehicle ahead is driving incorrectly, this vehicle will adopt the following strategy:
[0060] 1) When turning is prohibited in a reversible lane, and the vehicle in front uses its turn signal, if this vehicle has checked the lane sign, it will not warn the vehicle in front that it is driving incorrectly and should not follow. If this vehicle has not checked the lane sign, it will issue a voice warning that the vehicle in front is driving incorrectly and should not follow.
[0061] 2) When this lane prohibits straight travel or through traffic, and the vehicle in front proceeds straight, anticipate the turning position in advance and automatically activate the turn signal. If this vehicle has checked the lane sign and there is no indication that the vehicle in front is driving incorrectly, please do not follow. If this vehicle has not checked the lane sign, a voice prompt will remind this vehicle that the vehicle in front is driving incorrectly and not to follow.
[0062] Furthermore, when it is determined that the vehicle ahead is driving incorrectly, the following steps are also included: alerting the vehicles behind via the vehicle itself.
[0063] Specifically, during the day, the vehicle can remind vehicles behind it through text on the rear windshield, such as: "The vehicle in front is driving incorrectly, please do not follow." At night, the vehicle can remind vehicles behind it through text on the windshield and ground projection.
[0064] In this embodiment, the variable lane vehicle alert method provided further includes the following steps:
[0065] When the lane prohibits straight travel or passage, the vehicle will automatically activate the turn signal in advance, based on the predicted turning position. When the reversible lane prohibits passage, the turn signal will automatically activate at a preset distance from the starting point of the reversible lane (marked by a dashed line). When the reversible lane prohibits straight travel, the turn signal will automatically activate at a preset distance from the end point of the reversible lane.
[0066] The variable lane vehicle alert method provided by this invention activates a voice prompt to the driver to check the lane sign ahead when a zigzag lane line appears within a specific distance in front of the vehicle. If the driver has checked the lane sign and the vehicle in front is not driving according to regulations, the method does not alert the vehicle in front, but alerts the vehicles behind. If the driver has not checked the lane sign and the vehicle in front is not driving according to regulations, the method alerts both the vehicle in front and the vehicles behind. This variable lane vehicle alert method can provide warnings to following vehicles based on the current road conditions in different variable lane scenarios, promptly reminding the vehicle in front and the vehicles behind not to follow the vehicle in front incorrectly, thus avoiding being misled and incurring fines, and improving driving safety.
[0067] Based on the same inventive concept, the present invention also provides a variable lane vehicle alert system. Figure 3 This is a schematic diagram of a variable lane vehicle reminder system provided in an embodiment of the present invention. It is applied to the variable lane vehicle reminder method provided in the above embodiment and includes a judgment unit and a reminder unit.
[0068] The judgment unit prompts the driver to check the lane sign ahead when a reversible lane appears in front of the vehicle; and determines whether the driver has checked the lane sign ahead when a vehicle in front of the vehicle is driving incorrectly.
[0069] The decision unit has three decision functions:
[0070] First-level judgment: whether the lane ahead is a reversible lane. That is, the judgment unit needs to determine whether a reversible lane appears ahead. Specifically, whether a zigzag lane line appears ahead. If it appears, it is judged that the lane ahead is a reversible lane, and at this time the driver needs to be prompted to check the lane sign ahead.
[0071] Double judgment: Whether the vehicle ahead is driving incorrectly, specifically: when turning is prohibited in this lane, the vehicle ahead uses its turn signal; or when going straight or passing through this lane is prohibited. If either of these two conditions is met, the vehicle ahead is judged to be driving incorrectly.
[0072] Triple judgment: Whether the driver has looked at the sign ahead. Specifically, the minimum visible distance of the sign, D_min, is determined when the distance from the driver to the sign is greater than the current vehicle speed at the moment of the initial view, where D_min = VT, and V is the current vehicle speed, and T is the time required for the driver to recognize and understand the sign. The time required for the driver to recognize and understand the sign is usually 1.5-2 seconds.
[0073] Starting from the moment the vehicle reminds the driver to check the road sign ahead, observe the driver's line of sight. The time T during which the driver's gaze lingers on the direction of the road sign ahead is recorded. 累积 = Greater than the first preset time; T 累积 = The first preset time is 1.5-2 seconds, T 累积 To accumulate eye contact time, T i Let be the time spent looking at a certain point for the i-th time, and n be the number of times the object is looked at.
[0074] The reminder unit, when the driver has checked the sign ahead, will only remind vehicles behind that the vehicle ahead is driving incorrectly; if the driver has not checked the sign ahead, it will remind both the driver and vehicles behind that the vehicle ahead is driving incorrectly.
[0075] Please refer to the following: Figure 2 The specific strategy adopted by the reminder unit is as follows:
[0076] 1) When turning is prohibited in a reversible lane, and the vehicle in front uses its turn signal, if this vehicle has checked the lane sign, it will not warn the vehicle in front that it is driving incorrectly and should not follow. If this vehicle has not checked the lane sign, it will issue a voice warning that the vehicle in front is driving incorrectly and should not follow.
[0077] 2) When this lane prohibits straight travel or through traffic, and the vehicle in front proceeds straight, anticipate the turning position in advance and automatically activate the turn signal. If this vehicle has checked the lane sign and there is no indication that the vehicle in front is driving incorrectly, please do not follow. If this vehicle has not checked the lane sign, a voice prompt will remind this vehicle that the vehicle in front is driving incorrectly and not to follow.
[0078] Furthermore, when it is determined that the vehicle ahead is driving incorrectly, it also includes: alerting the vehicles behind via the vehicle's own warning.
[0079] Specifically, during the day, the vehicle can remind vehicles behind it through text on the rear windshield, such as: "The vehicle in front is driving incorrectly, please do not follow." At night, the vehicle can remind vehicles behind it through text on the windshield and ground projection.
[0080] In this embodiment, the variable lane vehicle reminder method provided further includes:
[0081] When the lane prohibits straight travel or passage, the vehicle will automatically activate the turn signal in advance, based on the predicted turning position. When the reversible lane prohibits passage, the turn signal will automatically activate at a preset distance from the starting point of the reversible lane (marked by a dashed line). When the reversible lane prohibits straight travel, the turn signal will automatically activate at a preset distance from the end point of the reversible lane.
[0082] Based on this, the variable lane vehicle warning system provided by the present invention also includes a display unit. The display unit is used to provide text reminders to vehicles behind via the rear windshield, or to provide reminders to vehicles behind via ground projection at night.
[0083] The variable lane vehicle alert system provided by this invention also includes a control unit. The control unit is used to control the vehicle to activate its turn signal in advance when a turn is required in a variable lane.
[0084] The variable lane vehicle alert system provided by this invention activates a voice prompt to the driver to check the lane sign ahead when a zigzag lane line appears within a specific distance in front of the vehicle. If the driver has checked the lane sign and the vehicle in front is not driving according to regulations, the system does not alert the vehicle in front, but alerts the vehicles behind. If the driver has not checked the lane sign and the vehicle in front is not driving according to regulations, the system alerts both the vehicle in front and the vehicles behind. This variable lane vehicle alert method can provide warnings to following vehicles based on the current road conditions in different variable lane scenarios, promptly reminding the vehicle in front and the vehicles behind not to follow the vehicle in front incorrectly, thus avoiding being misled and incurring fines, and improving driving safety.

The time T during which the driver's gaze lingers on the direction of the road sign ahead is recorded. 累积 = Greater than the first preset time; T 累积 = The first preset time is 1.5-2 seconds, T 累积 To accumulate eye contact time, T i Let be the time spent looking at a certain point for the i-th time, and n be the number of times the object is looked at.
3. The variable lane vehicle reminder method according to claim 2, characterized in that, The first preset time is adjusted according to environmental conditions, and the first preset time corresponds to the weather visibility, and the first preset time increases as the weather visibility decreases.
4. The variable lane vehicle reminder method according to claim 1, characterized in that, When a jagged lane marking appears ahead, it indicates that the lane ahead is a reversible lane.
5. The variable lane vehicle alert method according to claim 1, characterized in that, The erroneous driving includes: When turning is prohibited in this lane, the vehicle in front uses its turn signal; or When this lane prohibits straight-through or passage, the vehicle in front may proceed straight through.
6. The variable lane vehicle alert method according to claim 1, characterized in that, When the driver has checked the sign ahead, the vehicle will use its own vehicle to alert vehicles behind that the vehicle ahead is driving incorrectly. If the driver fails to check the sign ahead, alert the vehicle and vehicles behind to the incorrect driving ahead, including: When turning is prohibited in a reversible lane, if the vehicle in front signals and the driver has checked the lane sign, the vehicle in front will not be alerted to the wrong driving; if the driver has not checked the lane sign, the vehicle in front will be alerted to the wrong driving via voice. When straight-ahead driving or passage is prohibited in this lane, and the vehicle in front is driving straight through, the vehicle will automatically turn on its turn signal in advance to determine the turning position. If the driver has checked the lane sign, the vehicle will not be notified that the vehicle in front is driving incorrectly; if the driver has not checked the lane sign, the vehicle will be given a voice reminder that the vehicle in front is driving incorrectly.
