Description

Technical Field

[0001] The present invention relates to the field of autonomous driving technology, and in particular to an overtaking reminder method, system, electronic device and storage medium. Background Art

[0002] Currently, L3 autonomous driving technology is suitable for most vehicles and most road environments. L3 autonomous driving technology can achieve autonomous driving in common operating conditions, including straight driving, steering, acceleration, and braking. However, in some complex operating conditions, such as overtaking, the driver still needs to take over the vehicle.

[0003] When autonomous driving requires takeover, it alerts the driver through lights, sounds, and other prompts. However, current technologies only provide takeover prompts to the driver, and after the driver takes over, no further reminders are provided. Furthermore, in complex driving conditions, it is often difficult for the driver to make accurate judgments alone, and even if they suddenly take over, they are unable to respond quickly, compromising driving safety.

[0004] Especially in overtaking conditions, existing technologies are unable to provide accurate reminders and guide drivers on how to respond when overtaking or being overtaken.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0014] In some embodiments, the light-emitting device includes arc-shaped light-emitting bars distributed in the left area, right area and upper area of ​​the steering wheel. The step of pushing the third light reminder information through the light-emitting device includes: determining the arc-shaped light-emitting bar in the area where the overtaken direction is located, and the local arc-shaped area corresponding to the overtaken direction in the arc-shaped light-emitting bar in the upper area; controlling the arc-shaped light-emitting bar in the area where the overtaken direction is located and the local arc-shaped area to flash.

[0015] In some embodiments, the overtaking reminder method further includes the steps of: detecting the distance between the overtaking vehicle and the vehicle; if the distance is less than a preset value, increasing the flashing frequency and luminous brightness of the arc-shaped light bar in the area where the overtaking direction is located and the local arc-shaped area.

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure thorough and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures represent identical or similar structures, and thus a repeated description thereof will be omitted.

[0034] In addition, the accompanying drawings are merely schematic illustrations of the present invention and are not necessarily drawn to scale. Identical reference numerals in the figures denote identical or similar parts, and thus repetitive descriptions thereof will be omitted. Some of the blocks shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0035] The step numbers in the following method embodiments are only used to indicate different execution contents and do not limit the logical relationship and execution order between the steps. Unless otherwise specified, the features of each embodiment can be combined with each other.

[0036] Figure 1 The main steps of the overtaking reminder method in the embodiment are shown, referring to Figure 1 As shown, the overtaking reminder method in this embodiment mainly includes: in step S110, during the automatic driving process of the vehicle, an overtaking reminder instruction is generated according to real-time environmental data, and a circumferentially distributed light-emitting device is provided on the steering wheel of the vehicle; in step S120, according to the overtaking reminder instruction, a first light reminder information indicating grasping the steering wheel is pushed through the light-emitting device; in step S130, when a grasping action on the steering wheel is detected, an overtaking guidance instruction carrying the overtaking direction is generated according to the real-time environmental data; and in step S140, according to the overtaking guidance instruction, a second light reminder information indicating at least the overtaking direction is pushed through the light-emitting device.

[0037] This vehicle is equipped with L3 or higher autonomous driving technology. Control commands for the overtaking warning method are generated by the vehicle's autonomous driving controller or the central processing unit of the connected vehicle. Vehicles equipped with autonomous driving technology can communicate with each other through the central processing unit of the connected vehicle. This vehicle's steering wheel controller cooperates with the autonomous driving controller or the central processing unit of the connected vehicle to provide light warnings based on these control commands.

[0038] In step S110, real-time detection of the surrounding environment is achieved through detection devices installed in the vehicle. For example, sensors such as millimeter-wave radars, cameras, and ultrasonic radars are installed throughout the vehicle to detect and perceive the surrounding environment, thereby ensuring the accuracy of autonomous driving. The autonomous driving controller or central processing unit generates overtaking warning instructions based on real-time environmental data obtained by the sensors. For example, situations such as the following: the forward field of view is blocked, preventing the driver from observing the road ahead to respond to possible takeover requirements; the preceding vehicle is driving too slowly, preventing the vehicle from reaching its destination within the scheduled time; there is an obstacle on the road ahead that needs to be bypassed; and so on.

[0039] Figure 2 The structure of the steering wheel in the embodiment is shown, referring to Figure 2 As shown, in this embodiment, the steering wheel 200 is provided with circumferentially distributed light-emitting devices 210. The light-emitting devices 210 are light source devices that can emit colored light, such as LED (Light Emitting Diode) light sources, OLED (Organic Light-Emitting Diode) light sources, etc., to provide the driver with a variety of light reminders in different driving conditions. The steering wheel 200 can also be provided with a grip detection device (not specifically shown in the figure), such as capacitive sensors distributed on the outer and inner rings of the steering wheel 200 to detect whether the driver is accurately gripping the steering wheel 200.

[0040] In step S120, the steering wheel controller receives the overtaking reminder instruction and pushes the first light reminder information indicating grasping the steering wheel through the light-emitting device, so as to remind the driver to grasp the steering wheel accurately to take over the vehicle. The push method of the first light reminder information is: controlling the light-emitting device to flash at a predetermined flashing frequency, light brightness and light color, and the predetermined flashing frequency, light brightness and light color are determined according to the factory configuration or user configuration. For example, the factory configuration is: the light-emitting device emits yellow light with a brightness higher than the ambient light at a certain flashing frequency to attract the driver's attention and remind the driver to grasp the steering wheel. Over time, if the grasping detection device does not detect the grasping action, the flashing frequency and light brightness can be gradually increased, and the light color can be changed, such as emitting a high-frequency flashing red light that is significantly higher than the ambient light to provide a more obvious light reminder. Users can also set the push method of the first light reminder information according to their driving habits.

[0041] In step S130, when the steering wheel controller receives the gripping action signal, it confirms that the driver has correctly taken control of the vehicle and stops pushing the first light reminder message. Simultaneously, the autonomous driving controller or central processing unit receives the gripping action signal transmitted by the steering wheel controller and, based on real-time environmental data, determines whether overtaking to the left or right is more beneficial for the journey. It then generates an overtaking guidance instruction containing at least the overtaking direction and transmits it to the steering wheel controller.

[0042] In step S140, the steering wheel controller pushes a second light reminder message indicating at least the overtaking direction through the light-emitting device according to the overtaking guidance instruction. The driver can clearly know the accurate overtaking direction based on the second light reminder message, thereby assisting the driver in dealing with overtaking conditions.

[0043] In one embodiment, the lighting device includes curved light bars distributed on the left, right, and upper areas of the steering wheel to provide at least a clear directional reminder to the driver during overtaking. The step of transmitting the second light reminder information via the lighting device includes: determining a first curved light bar in an area in the overtaking direction, and controlling the curved light bar in the area in the overtaking direction to flash.

[0044] Figure 3 The schematic diagram of the layout of the light emitting device in the embodiment is shown. Figure 3 As shown, the light emitting device 210 includes a left arc-shaped light emitting bar 210a, a right arc-shaped light emitting bar 210b and an upper arc-shaped light emitting bar 210c. Each arc-shaped light emitting bar can be composed of a plurality of lamp beads, for example Figure 3 The diagram shows that each arc-shaped light bar includes 12 LEDs. If the overtaking direction carried in this overtaking guidance instruction is left, the arc-shaped light bar in the overtaking direction is the left arc-shaped light bar 210a. By controlling the left arc-shaped light bar 210a to flash, the driver is provided with clear overtaking direction guidance. The flashing pattern of the left arc-shaped light bar 210a is, for example, a high-frequency dynamic green light that matches the ambient light.

[0045] Furthermore, the overtaking guidance instruction also carries an overtaking steering angle, which points from the current driving direction of the vehicle to the overtaking direction. It is calculated by the automatic driving controller or the central processor based on real-time environmental data to provide the driver with a prompt on the degree of steering wheel rotation under overtaking conditions, assisting the driver in dealing with overtaking conditions.

[0046] Figure 4 The main steps of pushing the second light reminder information in the embodiment are shown, referring to Figure 4 As shown, after controlling the arc-shaped light bar in the area where the overtaking direction is located to flash, the method further includes: step S430, lighting up a portion of the arc-shaped light bar in the upper area, which is pointed from the center to the overtaking direction, so that the central angle of the portion of the arc-shaped light bar is equal to the overtaking steering angle; and step S440, determining the remaining steering angle according to the actual steering angle of the steering wheel and the overtaking steering angle, and adjusting the portion of the arc-shaped light bar in real time according to the remaining steering angle.

[0047] Combine Figure 3In the illustrated embodiment, after clearly conveying the instruction to overtake to the left by flashing the left curved light bar 210a several times, the left curved light bar 210a stops flashing, and the steering wheel angle required for overtaking is immediately indicated by a partially curved area in the upper curved light bar 210c, guiding the driver's steering action. In this embodiment, the partially curved area 210c' is obtained by determining, starting from the center of the upper curved light bar 210c (in some embodiments, from the light bead of the upper curved light bar 210c closest to the current driving direction "X"), along the direction pointing to the overtaking direction "L", a partially curved area 210c' having a central angle "α" equal to the overtaking steering angle. In other embodiments, other methods can be used to obtain the partially curved area, as long as the central angle corresponding to the partially curved area is equal to the overtaking steering angle, thereby providing a clear light reminder of the steering wheel angle required for overtaking.

[0048] The partial arc-shaped area 210 c ′ is illuminated in a manner such as making the partial arc-shaped area 210 c ′ emit green light equivalent to the ambient light, so as to provide a soft light reminder to the driver.

[0049] Furthermore, when the steering wheel is turned and an actual steering angle is generated, the remaining steering angle required for overtaking changes, so the partial arc area 210c' is adjusted accordingly to provide a dynamic steering wheel rotation operation degree prompt to assist the driver in flexibly responding to overtaking conditions.

[0050] For example, in the initial scenario, if the overtaking steering angle is 40°, the central angle "α" corresponding to the illuminated partial arc area 210c' will be equal to 40°. As the steering wheel generates an actual steering angle of 30°, the central angle "α" corresponding to the partial arc area 210c' is adjusted in real time to 10°, providing the driver with precise steering wheel rotation instructions. The remaining steering angle typically decreases as the overtaking process progresses, and the central angle "α" corresponding to the partial arc area 210c' gradually decreases until the vehicle successfully turns into the adjacent lane, at which point the illuminated reminder of the partial arc area 210c' ends.

[0051] In some scenarios, if the driver turns the steering wheel excessively, causing the actual steering angle of the steering wheel to be greater than the overtaking steering angle, the arc-shaped light bar in the opposite area of ​​the overtaking direction will be immediately controlled to flash as a warning light. Figure 3 In the embodiment shown, during overtaking to the left, if the steering wheel controller detects that the actual steering angle of the steering wheel is greater than the overtaking steering angle, it immediately stops lighting up the arc-shaped area 210c' in the upper arc-shaped light bar 210c for reminder, and instead emits a light warning flashing through the right arc-shaped light bar 210b, such as a high-frequency dynamic red light flashing, to indicate oversteering, so that the driver receives a strong light warning prompt and adjusts the actual steering angle of the steering wheel.

[0052] Furthermore, after controlling the arc-shaped light bar in the opposite area of ​​the overtaking direction to flash a light warning, it can also include: determining the reverse steering angle required to retract the steering wheel based on the actual steering angle of the steering wheel and the overtaking steering angle, and lighting up the second part of the arc-shaped area in the upper area pointing from the center in the opposite direction of the overtaking direction, so that the central angle of the second part of the arc-shaped area is equal to the direction steering angle, and adjusting the second part of the arc-shaped area in real time as the actual steering angle of the steering wheel changes, so as to guide the driver to accurately retract the actual steering angle of the steering wheel.

[0053] The lighting method and principle of the arc area in the second part can be found in Figure 3 The description of the partial arc-shaped area 210 c ′ in the illustrated embodiment will not be repeated here.

[0054] When the actual steering angle of the steering wheel is retracted into the range of the overtaking steering angle, the lighting reminder of the partial arc-shaped area 210c' is restored until the vehicle successfully turns to the adjacent lane.

[0055] The above instructions on lighting up a portion of the arc area so that the central angle of the portion of the arc area is equal to the steering angle required for overtaking conditions to provide clear steering wheel angle prompts can also be used for auxiliary driving conditions such as reversing and moving into a garage, providing the driver with prompts on the degree of operation required to turn the steering wheel in various driving conditions that require a steering wheel angle.

[0056] In some embodiments, the overtaking reminder method of each of the above embodiments further includes the step of sending a speed maintenance reminder to associated vehicles within a preset distance range that enter the dynamic overtaking space of the vehicle.

[0057] When generating overtaking guidance instructions, the vehicle's autonomous driving controller or the central processor of the Internet of Vehicles will calculate the path information required for this overtaking behavior and determine the dynamic overtaking space based on the path information. Figure 5 The scene diagram of the dynamic overtaking space in the embodiment is shown, referring to Figure 5 As shown, dynamic overtaking space 500 indicates a first path 510 from the current lane P1 of the host vehicle 100 into the adjacent lane P2, and a second path 520 from the adjacent lane P2 back to the current lane P1. In this embodiment, adjacent lane P2 is, for example, the lane opposite the current lane P1. Within the preset distance range of dynamic overtaking space 500, the acceleration of the vehicle being overtaken in the current lane P1, the deceleration of the preceding vehicle, and the acceleration of the preceding vehicle in the adjacent lane P2 may all cause the driver of the host vehicle 100 to be unable to react in time and result in a collision. Therefore, a speed maintenance reminder is sent to associated vehicles 101 within the preset distance range of the dynamic overtaking space 500 of the host vehicle 100 to ensure safety during the overtaking process and prevent collisions caused by sudden acceleration or deceleration of surrounding vehicles.

[0058] The method of sending the vehicle speed maintenance reminder to the associated vehicle 101 is, for example, sending the vehicle speed maintenance reminder information to the automatic driving controller of the associated vehicle 101 through the central processor of the Internet of Vehicles.

[0059] In this embodiment, during the process of the vehicle 100 entering the adjacent lane P2 from the current lane P1 along the first path 510, the driver is provided with prompts on the overtaking direction and the degree of steering wheel rotation operation through the flashing reminder of the left curved light bar and the lighting reminder of the partial curved area of ​​the upper curved light bar whose central angle is equal to the overtaking steering angle / remaining steering angle as described in the above embodiment; in the second half of the overtaking process, that is, during the process of the vehicle 100 returning to the current lane P1 from the adjacent lane P2 along the second path 520, similarly, the driver is provided with prompts on the overtaking return direction and the degree of steering wheel rotation operation through the flashing reminder of the right curved light bar and the lighting reminder of the partial curved area of ​​the upper curved light bar whose central angle is equal to the overtaking return steering angle / remaining return steering angle, which will not be repeated here.

[0060] Furthermore, in addition to the scenario of the vehicle actively overtaking as described in the above embodiment, the overtaking reminder method of the present invention also includes providing a light reminder via a light-emitting device on the steering wheel in the scenario of being overtaken. Specifically, in the scenario of being overtaken, the overtaking reminder method further includes the steps of: generating an overtaken reminder based on real-time environmental data, the overtaken reminder including the direction of the overtaken vehicle; and, based on the overtaken reminder, pushing a third light reminder message indicating the direction of the overtaken vehicle via the light-emitting device. In the present invention, the direction of the overtaken vehicle indicates the orientation of the overtaking vehicle, that is, the position of the overtaking vehicle (i.e., the following vehicle) relative to the vehicle.

[0061] Among them, the light-emitting device includes arc-shaped light-emitting bars distributed in the left area, right area and upper area of ​​the steering wheel. The step of pushing the third light reminder information through the light-emitting device includes: determining the arc-shaped light-emitting bar in the area where the overtaking direction is located, and the local arc-shaped area corresponding to the overtaking direction in the arc-shaped light-emitting bar in the upper area; controlling the arc-shaped light-emitting bar and the local arc-shaped area in the area where the overtaking direction is located to flash.

[0062] Figure 6 The light-emitting diagram of pushing the third light reminder information in the embodiment is shown, referring to Figure 6 As shown, in this embodiment, the lighting device 210 includes an arc-shaped light bar 210a distributed in the left area of ​​the steering wheel, an arc-shaped light bar 210b in the right area, and an arc-shaped light bar 210c in the upper area. When the overtaking direction is the left rear, that is, the overtaking vehicle overtakes the vehicle from the left rear, the light beads ( Figure 6The arc-shaped light strip 210a in the left area and the arc-shaped light strip 210c in the upper area) flashes and emits light, providing the driver with a reminder of being overtaken from the left rear. The lamp beads in the partial arc area of ​​the left half of the arc-shaped light strip 210a in the left area and the arc-shaped light strip 210c in the upper area can be illuminated in a certain flashing order. As long as the flashing mode, light color and brightness are different from the light information indicating overtaking, the driver can be provided with a clear reminder of being overtaken. When the direction of being overtaken is the right rear, that is, the overtaking vehicle overtakes the vehicle from the right rear, the arc-shaped light strip 210b in the right area and the lamp beads in the partial arc area of ​​the right half of the arc-shaped light strip 210c in the upper area ( Figure 6 Similarly, the right-side arc-shaped light bar 210b and the right half of the upper arc-shaped light bar 210c can be illuminated in a specific flashing sequence, with the flashing pattern, color, and brightness distinguishable from the overtaking light information, providing the driver with a clear warning of being overtaken.

[0063] Furthermore, the overtaking reminder method in the overtaking scenario also includes the steps of: detecting the distance between the overtaking vehicle and the vehicle; if the distance is less than a preset value, increasing the flashing frequency of the local arc area and enhancing the luminous brightness of the local arc area to prompt the driver to respond in time.

[0064] Figure 7 The schematic diagram of the lamp bead layout of the light emitting device in the embodiment is shown below. Figure 7 , indicating that the vehicle utilizes the light-emitting device 210 to provide reminders for different driving conditions throughout the entire process of autonomous driving. It should be noted that the light reminders under different driving conditions listed below are merely examples, and the light reminder scheme below can be combined with the features of any of the above embodiments.

[0065] Reference Figure 7 As shown, the left side arc-shaped light bar 210a includes L1 to L 12 The 12 lamp beads, the upper arc light strip 210c includes T1~T 12 The right side arc light strip 210b includes 12 lamp beads, numbered R1 to R 12 The upper curved light bar 210c is responsible for most of the dynamic lighting effects. The left and right curved light bars 210a and 210b provide stronger light stimulation in emergency situations or provide ambient lighting in autonomous driving scenarios. When providing light reminders, the steering wheel controller receives signals from the autonomous driving controller regarding the vehicle's current situation and issues light reminders based on the received situational signals.

[0066] In scenario one, the vehicle starts and self-checks normally. When the driver manually controls the steering wheel, that is, when a grip on the steering wheel is detected, if the surrounding environment is determined to be suitable for autonomous driving through analysis of real-time environmental data (camera, radar, map satellite signals, etc.), a visible but non-irritating green light corresponding to the intensity of the ambient light is emitted through the upper arc-shaped light bar 210c.

[0067] In scenario 2, when the vehicle is in scenario 1, if the driver takes his hands off the steering wheel, the vehicle will enter the automatic driving state according to the lane and speed before the hands are taken off. During the process of entering the automatic driving state, the upper arc-shaped light bar 210c emits a visible but non-irritating medium-frequency flashing green light with an intensity corresponding to the ambient light. The flashing range is gradually reduced by two lamp beads each time from the 12 lamp beads of the upper arc-shaped light bar 210c, that is, the first flash is T1 to T 12 Twelve lamp beads, the second flash T2~T 11 Ten lamp beads, the third flash T3~T 10 Eight LEDs... and so on. The sixth flash of T6 and T7 creates a dynamic timing effect. In this scenario, if the process of entering the automatic driving state is interrupted, the system will enter Scenario 3. If the dynamic lighting effect of this scenario is completed, that is, the timing ends, the system will enter Scenario 4.

[0068] In scenario three, the driver moves his hands back to the steering wheel in scenario two, and the process of entering the automatic driving state is interrupted. The twelve lamp beads of the upper arc-shaped light bar 210c flash three times at a high frequency, and then return to the dynamic effect of scenario one, that is, a visible but non-irritating green light with an intensity corresponding to the ambient light.

[0069] In scenario 4, after the dynamic light of scenario 2 is fully displayed, the vehicle enters the automatic driving state. At this time, the vehicle will plan the optimal path according to the map information provided by radar, satellite and other sensors, and use it to perform automatic driving. In the default state, the light reminder mode will start from the left and right areas and move towards the center with the intensity corresponding to the ambient light. The brightness is visible but not irritating. The order of the light beads is: the first flash is L1 to L4 and R 12 ~R9, the second flash L2~L5 and R 11 ~R8, the third flash L3~L6 and R 10 ~R7, ... and so on, until the four lamp beads T5~T8 are lit and then this process is repeated to indicate that the vehicle is moving forward normally. At the same time, this lighting effect can be opened to the driver, who can set the dynamic effect of the ambient light in the autonomous driving scenario he prefers.

[0070] In scenario five, when the vehicle, while in autonomous driving mode, approaches the edge of support for autonomous driving (including but not limited to situations where the camera cannot obtain valid information in rainy weather, map satellites are out of contact, and the satellite map lacks road details), the three-zone steering wheel light bar, i.e., the left curved light bar 210a, the upper curved light bar 210c, and the right curved light bar 210b, will flash yellow at a higher frequency than the ambient light, to alert the driver that autonomous driving is about to fail and to remind the driver to take over control.

[0071] In scenario six, when the vehicle enters an area that does not support autonomous driving under the scenario of autonomous driving, the three-zone light bar on the steering wheel will flash red light at a high frequency with a brightness significantly higher than the ambient light, to remind the driver that the autonomous driving has failed and to grab the steering wheel to take over the vehicle. At this time, the vehicle will also make corresponding controls, such as automatically parking in the emergency lane.

[0072] In scenario seven, when the vehicle is under manual control by the driver and drives to the edge of an area where autonomous driving is not supported or has just entered an area where autonomous driving is not supported, the upper arc-shaped light bar 210c flashes three or more times at a medium frequency with a blue light intensity equivalent to the ambient light intensity, and then enters a blue light intensity lower than the ambient light intensity.

[0073] In scenario eight, when the vehicle is under manual control by the driver and is in an area that does not support automatic driving (including but not limited to situations where the camera cannot obtain effective information in rainy days, the map satellite is lost, the satellite map lacks road details, etc.), blue light with a lower intensity than the ambient light is emitted through the upper arc-shaped light bar 210c.

[0074] In scenario nine, when the vehicle is under manual driving, the rear vehicle overtakes from the left rear. At this time, the radar can judge the distance. The lamp beads of the left arc light bar 210a and some lamp beads of the upper arc light bar 210c flash yellow light with a medium frequency slightly higher than the ambient light intensity. In a specific example, the flashing mode of the lamp beads of the left arc light bar 210a and the upper arc light bar 210c is: light up T1 and L2 respectively according to the distance between the rear vehicle and the vehicle. 11 、L 12 When the distance decreases by one unit (for example, 0.5 meters), T1, T2 and L9 to L 12 As the distance decreases, all the lamp beads T1 to T6 and the left arc-shaped light-emitting bar 210a are gradually lit.

[0075] In scenario 10, when the vehicle is under manual driving, the rear vehicle overtakes from the right rear. At this time, the radar can determine the distance. The lamp beads of the right arc-shaped light bar 210b and some lamp beads of the upper arc-shaped light bar 210c flash yellow light with a medium frequency slightly higher than the ambient light intensity. In a specific example, the flashing mode of the lamp beads of the right arc-shaped light bar 210b and the upper arc-shaped light bar 210c is: light up T respectively according to the distance between the rear vehicle and the vehicle. 12 When the distance between R1 and R2 decreases by one unit, T will light up. 11 、T 12 and R1~R4, gradually light up T7~T as the distance decreases 12 And all the lamp beads of the right arc-shaped light-emitting strip 210b.

[0076] In scenario 11, when the vehicle is under manual driving, the rear vehicle overtakes from the left rear. The vehicle's sensors cannot determine the exact distance at this time, so the driver is prompted to check the rearview mirror. The yellow light block flashes slightly higher than the ambient light intensity, starting from the lower left and climbing. The specific lighting order is: from L1 to L 12 The lights will light up cumulatively in sequence and circulate as a reminder before the following vehicle completes overtaking.

[0077] In scenario 12, when the vehicle is under manual driving, the rear vehicle overtakes from the right rear. The vehicle's sensors cannot determine the exact distance at this time, so the driver is prompted to check the rearview mirror. The yellow light block flashes slightly higher than the ambient light intensity, starting from the lower right and climbing up. The specific lighting order is: from R 12 The lights will light up cumulatively until R1, and the reminder will be circulated before the following vehicle completes overtaking.

[0078] In scenario thirteen, when the vehicle is under manual control by the driver, the vehicle is in an area that does not support automatic driving, and the driver takes his hands off the steering wheel. At this time, all the lamp beads in all areas, including the left arc-shaped light bar 210a, the upper arc-shaped light bar 210c and the right arc-shaped light bar 210b, flash red light at a high frequency that is stronger than the ambient light.

[0079] In Scenario 14, when the vehicle is under manual control in an area not supporting automated driving and driver fatigue is detected, all LEDs in the vehicle's area alternately flash red and yellow at a high frequency, brighter than ambient light, to alert the driver and passengers. It's important to note that when this scenario is triggered, the vehicle also provides various driver alerts, including but not limited to active seatbelt pretensioning, a loud wake-up tone in the audio system, and appropriate assisted acceleration and stopping.

[0080] In scenario 15, when the vehicle is under manual control by the driver, if the automatic driving controller determines that changing lanes to the left is more beneficial to the journey (such as when the vehicle ahead is slow or the traffic is congested and the left lane is in better condition or the left lane is in better condition, etc.), the lamp beads of the upper arc-shaped light bar 210c and the lamp beads of the left arc-shaped light bar 210a will emit high-frequency dynamic green light equivalent to the ambient light in a predetermined lighting sequence and cycle. In a specific example, the lighting sequence of the lamp beads of the upper arc-shaped light bar 210c and the lamp beads of the left arc-shaped light bar 210a is: T1~T4>L 12 、T1~T3>L 11 、L 12 、T1、T2>L 10 ~L 12 、T1>L9~L 12 >L8~L 11 >L7~L 10 >L6~L9>L5~L8>L4~L7>L3~L6>L2~L5>L1~L4>L1~L3, T4>L1, L2, T3, T4>L1, T2~T4>T1~T4, and cycle as road conditions permit. "," indicates priority, ">" indicates priority within a group, and "~" indicates simultaneous lighting.

[0081] In scenario 16, when the vehicle is under manual control by the driver, if the automatic driving controller determines that changing lanes to the right is more beneficial to the journey (such as when the right lane is in better condition due to traffic congestion or the right lane is in better condition), the lamp beads of the upper arc-shaped light bar 210c and the lamp beads of the right arc-shaped light bar 210b will emit high-frequency dynamic green lights equivalent to the ambient light in a predetermined lighting sequence and cycle. In a specific example, the lighting sequence of the lamp beads of the upper arc-shaped light bar 210c and the lamp beads of the right arc-shaped light bar 210b is: T9~T 12 >R1、T 10 ~T 12 >T 11 、T 12 、R1、R2>T 12 , R1~R3>R1~R4>R2~R5>R3~R6>R4~R7>R5~R8>R6~R9>R7~R 10 >R8~R 11 >R9~R 12 >R 10 ~R 12 、T9>R 11 、R 12 、T9、T 10 >R 12 、T9~T 11 >R9~R 12, and circulate when road conditions permit.

[0082] Through the lighting effects of the above scenarios, the scenario of the vehicle under autonomous driving conditions is improved, reminding the driver of the vehicle's situation and potential risks. The reminder method is suitable for ergonomics, human-computer interaction and the driver's traditional cognition.
