Description

Methods, devices, and equipment for indicating autonomous driving status

[0001] This application claims priority to Chinese patent application filed on November 27, 2024, with application number 202411717805.8 and entitled "Method, Apparatus and Device for Prompting Automatic Driving Status", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of autonomous driving, and in particular to a method, apparatus, and device for indicating autonomous driving status. Background Technology

[0003] The vehicle provides autonomous driving capabilities, which are achieved through an autonomous driving system. This system is categorized into multiple levels, including Level 3. Level 3 means the vehicle can perform autonomous driving tasks; the driver does not need to constantly monitor the vehicle, but must be able to take over control when required by the system. Furthermore, when the vehicle is in Level 3, it must alert the driver to this Level 3 autonomous driving status.

[0004] In existing technologies, the driver can be alerted to the vehicle's Level 3 autonomous driving status through indicator lights on the vehicle's dashboard.

[0005] However, the above-mentioned prompts are not prominent or intuitive enough, which prevents users from knowing the vehicle's autonomous driving status in a timely manner. As a result, users cannot adjust their driving behavior in time, which may lead to safety accidents. Summary of the Invention

[0006] This application provides a method, apparatus, and device for indicating the status of autonomous driving, in order to reduce safety risks.

[0007] In a first aspect, embodiments of this application provide a method for indicating autonomous driving status. The method is applied to an ambient lighting controller in a vehicle, and ambient lighting is provided in the driver's area inside the vehicle. The method includes:

[0008] The system receives ambient light function switch signals from the vehicle's driving information host and status information commands from the vehicle's central processing unit. The ambient light function switch signals represent the ambient light status at the current moment. The status information commands are determined based on the autonomous driving status of the vehicle's autonomous driving system at the current moment and indicate the ambient light effect.

[0009] If the ambient lighting function switch signal and the vehicle status determine that the ambient lighting prompt mode is to be activated, a status information command is sent to the ambient lighting controller in the vehicle. The status information command is used by the ambient lighting controller to control the lighting effect of the ambient lights based on the status information command. The lighting effect of the ambient lights is used to prompt the driver that the autonomous driving status is activated.

[0010] In one possible implementation, the vehicle status includes vehicle mode information and vehicle usage mode information, wherein the vehicle mode information represents the vehicle's factory state and the vehicle usage mode information represents the vehicle's operating state.

[0011] If the ambient lighting activation prompt mode is determined based on the ambient lighting function switch signal and the vehicle's status, it includes:

[0012] If the vehicle mode information indicates that the vehicle's factory state is the user's usage state, the vehicle usage mode information indicates that the vehicle's operating state is the power-on mode, and the ambient light function switch signal indicates that the ambient light is on, then the ambient light prompt mode is activated.

[0013] In one possible implementation, the autonomous driving state is determined based on information about the vehicle's driving environment.

[0014] The status information command is determined based on the autonomous driving status and a first preset mapping relationship, which is the correspondence between the autonomous driving status and the value of the status information command.

[0015] In one possible implementation, the autonomous driving state is obtained by inputting the vehicle's driving environment information into a preset model for identification.

[0016] Alternatively, the autonomous driving state is determined based on the vehicle's driving environment information and a second preset mapping relationship, which is the correspondence between the vehicle's driving environment information and the autonomous driving state.

[0017] In one possible implementation, when the ambient light function switch signal is set to 1, the ambient light is in the on state at the current moment.

[0018] When the value of the ambient light function switch signal is 0, the ambient light is in the off state at the current moment.

[0019] In one possible implementation, the value of the status information command corresponds to the lighting effect of the ambient light.

[0020] Secondly, embodiments of this application provide an automatic driving status alert device. The device is applied to an ambient lighting controller in a vehicle. An ambient light is provided in the driver's area inside the vehicle. The device includes:

[0021] The receiving unit is used to receive the ambient light function switch signal sent by the driving information host in the vehicle, and to receive the status information instruction sent by the central processing unit in the vehicle; wherein, the ambient light function switch signal represents the ambient light status at the current moment; the status information instruction is determined based on the autonomous driving status of the vehicle's autonomous driving system at the current moment, and the status information instruction indicates the lighting effect of the ambient light.

[0022] The determining unit is used to determine the ambient light activation prompt mode based on the ambient light function switch signal and the vehicle status.

[0023] The sending unit is used to send status information instructions to the ambient lighting controller in the vehicle; wherein, the status information instructions are used by the ambient lighting controller to control the lighting effect of the ambient lights based on the status information instructions; the lighting effect of the ambient lights is used to indicate the autonomous driving status to the driver.

[0024] In one possible implementation, the vehicle status includes vehicle mode information and vehicle usage mode information, wherein the vehicle mode information represents the vehicle's factory state and the vehicle usage mode information represents the vehicle's operating state.

[0025] The determining unit is specifically used to: determine the activation of the ambient light prompt mode if the vehicle mode information indicates that the vehicle's factory state is the user's usage state, the vehicle usage mode information indicates that the vehicle's operating state is the power-on mode, and the ambient light function switch signal indicates that the ambient light is on.

[0026] In one possible implementation, the autonomous driving state is determined based on information about the vehicle's driving environment.

[0027] The status information command is determined based on the autonomous driving status and a first preset mapping relationship, which is the correspondence between the autonomous driving status and the value of the status information command.

[0028] In one possible implementation, the autonomous driving state is obtained by inputting the vehicle's driving environment information into a preset model for identification.

[0029] Alternatively, the autonomous driving state is determined based on the vehicle's driving environment information and a second preset mapping relationship, which is the correspondence between the vehicle's driving environment information and the autonomous driving state.

[0030] In one possible implementation, when the ambient light function switch signal is set to 1, the ambient light is in the on state at the current moment.

[0031] When the value of the ambient light function switch signal is 0, the ambient light is in the off state at the current moment.

[0032] In one possible implementation, the value of the status information command corresponds to the lighting effect of the ambient light.

[0033] Thirdly, embodiments of this application provide an ambient light controller, including: a memory and a processor.

[0034] The memory stores the instructions that the computer executes.

[0035] The processor executes computer execution instructions stored in memory, causing the processor to perform the first aspect and / or various possible implementations of the first aspect as described above.

[0036] Fourthly, embodiments of this application provide a vehicle, in which an ambient light controller as described in the third aspect above is provided, and ambient light is provided in the driver's area inside the vehicle; furthermore, the vehicle is provided with a driver information host, a central processing unit, and a body domain control unit.

[0037] The driving information host and central processing unit are connected to the vehicle body domain control unit; the vehicle body domain control unit is connected to the ambient lighting controller, and the ambient lighting controller is connected to the ambient lighting.

[0038] Fifthly, embodiments of this application provide a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, are used to implement the first aspect and / or various possible implementations of the first aspect.

[0039] Sixthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the first aspect and / or various possible implementations of the first aspect.

[0040] The autonomous driving status indication method provided in this application involves a central processing unit determining and sending a status information command based on the state of the autonomous driving system. This status information command indicates the ambient lighting effect. The vehicle body control unit then sends the status information command to the ambient lighting controller to control the ambient lights installed in the vehicle to execute their lighting effects. Compared to prompts via the instrument panel or central control screen, ambient lighting effect indications are more intuitive and eye-catching for the driver. Drivers can quickly identify the current state of the vehicle's autonomous driving system and adjust their driving behavior accordingly, thereby improving the safety of the autonomous driving system and reducing safety risks.

[0041] Furthermore, the ambient lighting associated with the ambient lighting indicator mode is located in the driver's area. This limits the indicator range of the ambient lighting effect to the area directly in front of the driver's eyes. The driver can perceive the ambient lighting effect using only peripheral vision; in other words, the ambient lighting's dynamic light signals allow the driver to more quickly grasp the status of the autonomous driving system and adjust their driving behavior accordingly, such as actively taking control of the vehicle. This improves the user experience and the safety of the autonomous driving system. Attached Figure Description

[0052] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] The development of technologies such as artificial intelligence has promoted the autonomous driving function of vehicles.

[0055] Based on the capabilities of the vehicle's driving system and the driver's role in the driving process, the following levels of autonomous driving are distinguished:

[0056] Level 0 (L0, also known as no automation): There are no automatic driving functions. The driver is in full control of the vehicle and is fully responsible for all operations such as acceleration, braking, and steering.

[0057] Level 1 (L1, also known as driver assistance): The vehicle has a single autonomous driving function, such as Adaptive Cruise Control (ACC) or Lane Keeping Assist (LKA). These functions can control the vehicle's speed or direction, but the driver must be ready to take over control at any time.

[0058] Level 2 (L2, also known as partial automation): The vehicle can control acceleration, braking, and steering simultaneously, but the driver must constantly monitor the driving environment and be ready to take over at any time. This level of autonomous driving system is often referred to as "semi-autonomous driving".

[0059] Level 3 (L3, also known as conditional automation): The vehicle is fully in control of driving tasks, including acceleration, braking, and steering, under specific conditions. Under these conditions, the driver does not need to constantly monitor the environment, but must be able to take over control promptly when requested by the system.

[0060] Level 4 (L4, also known as high automation): The vehicle is fully capable of controlling all driving tasks under certain conditions without driver intervention. Even if the driver fails to respond in a timely manner when requested by the system, the vehicle can safely handle the driving task.

[0061] Level 5 (L5, also known as full automation): The vehicle can drive completely autonomously in all road and environmental conditions without any driver intervention. This level of automated driving system can operate the vehicle safely in any situation.

[0062] As can be seen from the above classification of autonomous driving levels, for Level 3 autonomous driving systems, the driver needs to immediately take over control of the vehicle when the autonomous driving system is unable to safely control the vehicle; this requires the vehicle to issue a prompt message to the driver so that the driver is aware of the current status of the autonomous driving system.

[0063] In one example, the driver is alerted to the status of the autonomous driving system via indicator lights on the vehicle's dashboard.

[0064] Alternatively, prompts can be issued to the driver via text messages displayed on the central control screen. For example, the displayed text messages could be "Autonomous driving activated" or "Please take over immediately."

[0065] However, the aforementioned methods of issuing prompts are not prominent or intuitive enough, which prevents users from being informed of the status of autonomous driving in a timely manner and thus prevents them from adjusting their driving behavior accordingly, potentially leading to safety accidents.

[0066] The method for indicating the autonomous driving status provided in this application aims to solve the above-mentioned technical problems of the prior art.

[0067] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0068] Figure 1 is a flowchart illustrating the autonomous driving status notification method provided in this application. As shown in Figure 1, the method is applied to an ambient lighting controller in a vehicle. Ambient lighting is provided in the driver's area inside the vehicle. The method includes:

[0069] S101. Receive the ambient light function switch signal sent by the driving information host in the vehicle, and receive the status information instruction sent by the central processing unit in the vehicle; wherein, the ambient light function switch signal represents the ambient light status at the current moment; the status information instruction is determined based on the autonomous driving status of the vehicle's autonomous driving system at the current moment, and the status information instruction indicates the lighting effect of the ambient light.

[0070] For example, the executing entity of this application embodiment may be an electronic device, a server, a terminal device, or other device or equipment capable of executing the solution of this embodiment, and there is no limitation thereto. This embodiment describes the executing entity as an ambient light controller.

[0071] The ambient lighting controller receives ambient lighting function switch signals from the vehicle's Display Head Unit (DHU, also known as the driver information and entertainment system). The ambient lighting controller and the DHU can be connected via a Flexray bus; the Flexray bus is a time-triggered dual-channel bus capable of data transmission, with a single-channel data transmission rate of 10 Mbps.

[0072] The ambient light function switch signal (AmbLiAll) indicates the ambient light status at the current moment; the ambient light status can include an on state and an off state.

[0073] The ambient lighting controller also receives status information commands from the vehicle's central processing unit (Autonomous Driving Main Computer, ADMC, also known as the autonomous driving central main processor). The ambient lighting controller and the central processing unit can be connected via the Flexray bus.

[0074] The vehicle is also equipped with a Central Electronic Module (CEM), which connects the ambient lighting controller to the Central Electronic Module via a bus.

[0075] The central processing unit determines the different values ​​contained in the status information instruction (AD4AmbLiReqGroup.AmbLiReq) based on the different states of the autonomous driving system; the states of the autonomous driving system include the following:

[0076] The first state is system activation. In this state, it indicates that the vehicle's autonomous driving system has been activated and is controlling the vehicle's movement.

[0077] The second type is the risk-free state. In this state, it indicates that there is no risk in the current driving environment, and the autonomous driving system can fully and safely control the vehicle.

[0078] The third type is the low-risk state. In this state, it indicates that there are some risks in the current driving environment, but the autonomous driving system can control these risks and can completely and safely control the vehicle's movement.

[0079] The fourth type is the high-risk state. In this state, the risks present in the current driving environment exceed the processing capabilities of the autonomous driving system, and the system may be unable to safely control the vehicle.

[0080] The fifth type is the takeover request state. In this state, the risks present in the current driving environment are determined to exceed the processing capabilities of the autonomous driving system, and the autonomous driving system is unable to safely control the vehicle. The driver needs to immediately take over control of the vehicle.

[0081] Different values ​​in the status information command indicate different lighting effects of the ambient light. For example, an ambient light may include multiple light-emitting diodes (LEDs), also known as LED beads; the lighting effect of the ambient light may include the color of the LED beads, the brightness of the LED beads, and the blinking period of the LED beads, etc.

[0082] S102. If the ambient light indicator mode is determined to be activated based on the ambient light function switch signal and the vehicle status, a status information instruction is sent to the ambient light controller in the vehicle. The status information instruction is used by the ambient light controller to control the ambient light effect based on the status information instruction. The ambient light effect is used to indicate the autonomous driving status to the driver.

[0083] For example, the ambient lighting controller determines whether to activate the ambient lighting alert mode based on the ambient lighting function switch signal and the vehicle's status.

[0084] For example, if the ambient lighting function switch signal indicates that the ambient lighting is on, and the vehicle status matches the preset vehicle status, then the vehicle body control unit determines to activate the ambient lighting prompt mode. For example, the preset vehicle status could be a user mode; where the user mode indicates that the vehicle is in a user-driven state.

[0085] By setting the criteria for activating the ambient lighting alert mode, it helps ensure that the ambient lighting effect indicating the status of the autonomous driving system is activated only under appropriate conditions. This reduces the chance of the ambient lighting effect being triggered incorrectly due to misjudgment of vehicle status or user intent, avoids unnecessary interference to the driver, and reduces energy consumption.

[0086] It is worth noting that in this embodiment, the ambient lighting is located in the driver's area inside the vehicle; that is, the ambient lighting related to the ambient lighting indicator mode is located in the driver's area. The advantage of this arrangement is that the indicator range of the ambient lighting effect is limited to the area directly in front of the driver's eyes. The driver can perceive the ambient lighting effect using only peripheral vision, i.e., the ambient lighting dynamic light language. The driver can more quickly obtain the status of the autonomous driving system and thus adjust their driving behavior, such as actively taking over control of the vehicle; thereby improving the user experience and the safety of the autonomous driving system.

[0087] However, this embodiment does not limit the setting area of ​​other ambient lights in the vehicle, that is, it does not limit the setting area of ​​ambient lights that are unrelated to the ambient light indicator mode; for example, ambient lights that are unrelated to the ambient light indicator mode can be set on the inside of the vehicle doors, the roof of the vehicle, and the seat area of ​​the vehicle, etc.

[0088] After the ambient light controller determines that the ambient light prompt mode has been activated, the ambient light controller generates and sends a status information command.

[0089] The Ambient Lights Module (ALM) controls the ambient lights to execute the desired lighting effects based on the received status information commands. Specifically, the ambient light controller converts the status information commands into lighting effect control signals and transmits these signals to the ambient light module; the ambient light module then controls the ambient lights to execute the desired lighting effects based on these signals.

[0090] By observing the ambient lighting effects, drivers can identify the current state of the vehicle's autonomous driving system. Based on this state, drivers can adjust their driving behavior to ensure driving safety.

[0091] For example, drivers can understand the correspondence between the ambient lighting effects and the state of the autonomous driving system by reading the user manual, instruction manual, or watching a simulated demonstration video of the vehicle; thus, drivers can know the current state of the vehicle's autonomous driving system by observing the ambient lighting effects.

[0092] The autonomous driving status prompting method provided in this application embodiment involves a central processing unit determining and sending a status information command based on the status of the autonomous driving system. This status information command indicates the ambient lighting effect. The ambient lighting controller generates and sends the status information command to control the ambient lights installed in the vehicle to execute their lighting effects. Compared to prompts via the instrument panel or central control screen, ambient lighting effect prompts are more intuitive and eye-catching for the driver. Drivers can quickly identify the current status of the vehicle's autonomous driving system and adjust their driving behavior accordingly, thereby improving the safety of the autonomous driving system and reducing safety risks.

[0093] Furthermore, in this embodiment, the ambient light associated with the ambient light indicator mode is located in the driver's area. This limits the indicator range of the ambient light effect to the area directly in front of the driver's eyes, allowing the driver to perceive the effect using only peripheral vision. In other words, the ambient light's dynamic lighting signals enable the driver to more quickly grasp the status of the autonomous driving system and adjust their driving behavior accordingly, such as proactively taking control of the vehicle. This improves the user experience and the safety of the autonomous driving system.

[0094] Figure 2 is a flowchart illustrating the method for indicating the autonomous driving status provided in this application. As shown in Figure 2, this embodiment, based on the embodiment in Figure 1, provides a detailed description of the method for indicating the autonomous driving status. The method includes:

[0095] S201. Receive the ambient light function switch signal sent by the driving information host in the vehicle, and receive the status information instruction sent by the central processing unit in the vehicle; wherein, the ambient light function switch signal represents the ambient light status at the current moment; the status information instruction is determined based on the autonomous driving status of the vehicle's autonomous driving system at the current moment, and the status information instruction indicates the lighting effect of the ambient light.

[0096] For example, the executing entity of this application embodiment may be an electronic device, a server, a terminal device, or other device or equipment capable of executing the solution of this embodiment, and there is no limitation thereto. This embodiment describes the executing entity as an ambient light controller.

[0097] For details of this step, please refer to step S101; it will not be repeated here.

[0098] S202. If the ambient light function switch signal and the vehicle status determine that the ambient light prompt mode is to be activated, a status information instruction is sent to the ambient light controller in the vehicle. The status information instruction is used by the ambient light controller to control the lighting effect of the ambient light based on the status information instruction. The lighting effect of the ambient light is used to prompt the driver of the autonomous driving status.

[0099] In one example, the vehicle status includes vehicle mode information and vehicle usage mode information, where the vehicle mode information represents the vehicle's factory state and the vehicle usage mode information represents the vehicle's operating state; step S202, "determining to activate the ambient light prompt mode based on the ambient light function switch signal and the vehicle's status," includes the following process:

[0100] If the ambient light function switch signal and the vehicle status determine the activation of the ambient light prompt mode, the following applies: if the vehicle mode information indicates that the vehicle's factory state is the user usage state, the vehicle usage mode information indicates that the vehicle's operating state is the power-on mode, and the ambient light function switch signal indicates that the ambient light status is the on state, then the ambient light prompt mode is activated.

[0101] In one example, when the ambient light function switch signal is set to 1, the ambient light is in the on state at the current moment.

[0102] When the value of the ambient light function switch signal is 0, the ambient light is in the off state at the current moment.

[0103] For example, the ambient lighting controller determines the vehicle's status; for instance, the vehicle status includes vehicle mode information and vehicle usage mode information. The vehicle mode information represents the vehicle's factory state, including production mode, transportation mode, and normal mode (also known as normal mode); wherein, production mode represents the vehicle being in the factory production process; transportation mode represents the vehicle's mode during transportation after factory production is completed; and normal mode represents the vehicle's mode when used by the user after delivery to the user.

[0104] Vehicle usage mode information represents the vehicle's operating status. Vehicle usage mode information includes power-on mode (also known as driving mode), sleep mode, etc. Power-on mode indicates that the vehicle's high-voltage battery is in a power-supply state, while sleep mode indicates that the vehicle's high-voltage battery is in a power-dissipating state.

[0105] The driver information unit determines and sends an ambient light function switch signal to the ambient light controller based on the status of the ambient light. For example, if the ambient light is on, the ambient light function switch signal has a value of 1; if the ambient light is off, the ambient light function switch signal has a value of 0.

[0106] If the ambient lighting controller determines that the vehicle mode information includes normal mode (i.e., the vehicle is in use by the user), and the vehicle usage mode information includes power-on mode and the ambient lighting function switch signal value is 1, then it will activate the ambient lighting indicator mode and proceed with subsequent ambient lighting effect control. Otherwise, it will not activate the ambient lighting indicator mode.

[0107] In one example, the autonomous driving state is determined based on information about the vehicle's driving environment.

[0108] The status information command is determined based on the autonomous driving status and a first preset mapping relationship, which is the correspondence between the autonomous driving status and the value of the status information command.

[0109] For example, firstly, the vehicle's driving environment information is collected using sensors deployed in the vehicle (e.g., LiDAR, cameras). This driving environment information includes, for instance, information about other vehicles, pedestrians, traffic signals, road conditions, road signs, and weather conditions. The sensors then transmit the collected driving environment information to the central processing unit.

[0110] The central processing unit (CPU) determines the state of the vehicle's autonomous driving system based on the received driving environment information, and then generates and sends state information commands. For example, this can be achieved through the following two processes.

[0111] Firstly, there is a correspondence between the state of the autonomous driving system and the driving environment information. For example, based on the various information included in the driving environment information, the driving environment information is divided into four levels: Level 1, Level 2, Level 3, and Level 4. If the driving environment information is determined to be Level 1, the corresponding autonomous driving system is in a risk-free state; if it is determined to be Level 2, the corresponding autonomous driving system is in a low-risk state; if it is determined to be Level 3, the corresponding autonomous driving system is in a high-risk state; and if it is determined to be Level 4, the corresponding autonomous driving system is in a takeover request state.

[0112] For example, the levels of driving environment information can be classified according to the following criteria.

[0113] The conditions for the first level can be:

[0114] Other vehicle information meets the following standards: maintaining a safe distance, driving steadily, and showing no signs of sudden lane changes or abrupt braking; pedestrian information meets the following standards: no pedestrians are on the vehicle's expected path, or pedestrian behavior is predictable and follows traffic rules. Traffic signal information meets the following standards: all traffic signals and signs are clearly identifiable, and there are no conflicting or unclear signals. Road surface condition information meets the following standards: the road surface is dry, flat, and free of obstacles or hazards (e.g., potholes, gravel, etc.). Road sign information meets the following standards: all road signs are clearly visible and consistent with the navigation system information. Weather condition information meets the following standards: sunny or slightly cloudy, with high visibility and no rain, snow, or fog that may impair visibility.

[0115] The conditions for the second level can be:

[0116] Other vehicle information meets the following criteria: Vehicles may be traveling nearby, but their speed and behavior are stable, and the autonomous driving system can predict and adapt to their behavior. Pedestrian information meets the following criteria: Pedestrians are near vehicles, but there is sufficient time and space to avoid them or stop. Traffic signal information meets the following criteria: Traffic signals may have some ambiguity, but the autonomous driving system can verify them using other sensor or navigation data. Road condition information meets the following criteria: The road surface may be slightly slippery or have a few obstacles, but the autonomous driving system can identify them and safely detour around them. Road sign information meets the following criteria: Some road signs may not be clear enough, but the system can compensate using other data sources. Weather condition information meets the following criteria: Light rain, snow, or fog, but it does not affect the sensor performance and visibility of the autonomous driving system.

[0117] The conditions for the third level can be:

[0118] Other vehicle information meets the following criteria: Vehicle behavior is unstable or unpredictable, such as frequent lane changes, sudden braking, or speeding. Pedestrian information meets the following criteria: Pedestrians are in the vehicle's path or their behavior is sudden, giving the autonomous driving system limited reaction time. Traffic signal information meets the following criteria: Traffic signals are damaged, obstructed, or conflicting, making them difficult to interpret correctly. Road condition information meets the following criteria: There is a large amount of water, snow, ice, or significant obstacles on the road surface, affecting the vehicle's stability and handling. Road sign information meets the following criteria: Key road signs are missing or unclear, increasing navigation uncertainty. Weather condition information meets the following criteria: Severe rain, snow, fog, or other low-visibility weather conditions severely affect sensor performance and the driver's vision.

[0119] The conditions for the fourth level can be:

[0120] Road condition information meets the following criteria: Poor road conditions, such as severe road surface problems like deep water, snow, ice, or other conditions that make vehicle handling difficult. Other vehicle or pedestrian information meets the following criteria: When the system detects an impending collision or other emergency, and automatic emergency braking or other avoidance measures cannot prevent the danger; or, as in traffic congestion, pedestrian-intensive areas, or traffic control due to special events. Weather condition information meets the following criteria: When environmental conditions change rapidly, such as sudden heavy rain, fog, or storms, exceeding the system's response capabilities. System malfunction or anomaly: The autonomous driving system software or hardware malfunctions, or the system behaves abnormally, making safe driving impossible.

[0121] Secondly, based on the first preset mapping relationship, the value of the status information command can be determined by the status of the autonomous driving system.

[0122] For example, if the autonomous driving system is determined to be in a system-activated state, the value of the status information instruction is 1; if the autonomous driving system is determined to be in a risk-free state, the value of the status information instruction is 2; if the autonomous driving system is determined to be in a low-risk state, the value of the status information instruction is 3; if the autonomous driving system is determined to be in a high-risk state, the value of the status information instruction is 4; if the autonomous driving system is determined to be in a takeover request state, the value of the status information instruction is 5; if the autonomous driving system is determined to be in another state, that is, the current state of the vehicle's autonomous driving system does not belong to any of the above states, the value of the status information instruction is 0.

[0123] In one example, the autonomous driving state is obtained by inputting the vehicle's driving environment information into a preset model for identification.

[0124] Alternatively, the autonomous driving state is determined based on the vehicle's driving environment information and a second preset mapping relationship, which is the correspondence between the vehicle's driving environment information and the autonomous driving state.

[0125] For example, the central processing unit collects driving environment information through sensors deployed in the vehicle and inputs the driving environment information into a preset model; after the preset model identifies the driving environment information, it processes the driving environment information and the state of the autonomous driving system according to the correspondence between the driving environment information and the state of the autonomous driving system, that is, the second preset mapping relationship, to obtain the state of the autonomous driving system.

[0126] For example, the preset model can identify and process driving environment information through the following process; where driving environment information includes information on other vehicles, pedestrians, traffic signals, road conditions, road signs, and weather conditions.

[0127] The preset model processes driving environment information to obtain feature values ​​for other vehicles, pedestrians, traffic signals, road conditions, road signs, and weather conditions.

[0128] The preset model assigns different weight values ​​to each of the following features based on their impact on driving safety: other vehicle information features, pedestrian information features, traffic signal information features, road surface condition information features, road sign information features, and weather condition information features. This results in weight values ​​for other vehicle information features, pedestrian information features, traffic signal information features, road surface condition information features, road sign information features, and weather condition information features. The allocation of these weight values ​​can be determined based on expert experience, statistical analysis, or machine learning models.

[0129] The comprehensive risk value is determined based on the weight values ​​of other vehicle information features, pedestrian information features, traffic signal information features, road surface condition information features, road sign information features, and weather condition information features. Specifically, the comprehensive risk value is calculated by multiplying each feature value by its corresponding feature weight value (for example, the feature weight value corresponding to the feature value of other vehicle information features is multiplied by the weight values ​​of the other vehicle information features and then summed; that is, the comprehensive risk value is calculated using a weighted method).

[0130] Based on the comprehensive risk value, the state of the autonomous driving system is determined. For example, it is determined what preset threshold the comprehensive risk value falls within, and thus the state of the autonomous driving system is determined to be a risk-free state, a low-risk state, a high-risk state, or a takeover request state. The preset threshold can be determined through historical data analysis, expert opinions, or test data.

[0131] S203, The correspondence between the value of the status information command and the lighting effect of the ambient light.

[0132] For example, in the ambient lighting prompt mode, the lighting effect of the ambient light is determined according to the value of the status information command. In this embodiment, the ambient light includes 100 LED beads, numbered from 1 to 100 (positive integers) from left to right, with reference to the vehicle's driver's cab dashboard; among them, the LED beads corresponding to the driver's area are numbered 1 to 39.

[0133] The ambient lighting controller sends lighting effect control signals to the ambient lighting module. For example, the lighting effect control signal includes several control messages, the duration of each action, and the number of action frames. Each control message corresponds to the control information of a specific LED bead. The control information includes: the LED bead's number, its color, its brightness, and the interval (also called the period) between each action. Each LED bead number corresponds to two LED beads, for example, they can be referred to as the first LED bead and the second LED bead. The correspondence between each LED bead's number and the LED beads is shown in the table below. For brevity, only a portion of the LED bead number and LED bead correspondence is listed here, and this does not mean that this solution only includes the LED beads listed below.

[0134] Each control message consists of 8 bytes. The first 4 bytes (also known as the high byte) of each control message control the first LED corresponding to the LED number contained in the control message, and the last 4 bytes (also known as the low byte) of each control message control the second LED corresponding to the LED number contained in the control message.

[0135] As shown in the table below, LED bead number 404 controls the first LED bead to be white (RGB value 255, 255, 255) with a brightness value of 31, and the second LED bead to be red (RGB value 255, 0, 0) with a brightness value of 20. The control message content represented in hexadecimal is: ID = 0x404; FF 00 00 14FF FF FF 1F.

[0136] The lighting effects of each ambient light are explained in detail below.

[0137] If the ambient lighting controller determines that the status information command value is 0, then the ambient lighting effect will not be executed. In the state where the ambient lighting effect is not executed, the ambient lighting will maintain its original effect. For example, if the driver sets the ambient lighting color to a solid yellow, then the original effect of the ambient lighting will be a solid yellow. When the ambient lighting indicator mode is activated, if the ambient lighting effect indicates that it is not executed, the ambient lighting will maintain the solid yellow effect set by the driver.

[0138] If the ambient light controller determines that the status information command is 1, then the ambient light effect is the first effect. The first effect will be described below based on the timing diagram of the first effect shown in Figure 3. It should be noted that Figure 3 is a grayscale image; the original image shows blue LED beads.

[0139] In Figure 3, viewed from left to right, LEDs numbered 1-39 are set to blue (RGB values ​​40, 100, 255). The values ​​in the table represent brightness values ​​(an empty table represents a brightness of 0 for the corresponding LED). Viewed from top to bottom, the table shows the color and brightness of LEDs numbered 1-39 in each frame (i.e., each action). For example, in the 13th action (corresponding to step 13 in Figure 3), the brightness of LEDs numbered 3-37 is 31, while the brightness of LEDs numbered 1-2 and 38-39 is 0. In the first lighting effect, the interval between each frame (i.e., the duration of each action) is 40ms, and the number of action frames is 51.

[0140] The aforementioned first lighting effect achieves the following visual effect: the driver observes that the LED in the center area of ​​the steering wheel (in this embodiment, the corresponding LED is number 20) lights up first, and then expands to both sides of the cab; when the brightness of all LEDs reaches the set maximum value (in this embodiment, the maximum brightness is 31), the brightness of each LED gradually decreases to 0, creating a fade-out effect. Meanwhile, the other LEDs on the dashboard (numbered 40-100) are not controlled by the ambient lighting indicator mode and still display the user-set color.

[0141] If the ambient light controller determines that the status information command is 2, then the ambient light effect is the second effect. The second effect will be described below based on the timing diagram of the second effect shown in Figure 4. It should be noted that Figure 4 is a grayscale image; the original image shows blue LED beads.

[0142] As shown in Figure 4, in the second lighting effect, LED beads numbered 1-39 are set to blue (RGB values ​​of 40, 100, and 255); the interval between each action is 20ms, and the number of frames for the second lighting effect is 29 frames.

[0143] The aforementioned second lighting effect achieves the following visual effect: LED beads numbered 1-39 gradually brighten from dark (brightness gradually increases), and after reaching a set maximum brightness (in this embodiment, the maximum brightness is 31), they gradually dim again. This process is repeated once, meaning the second lighting effect includes two such lighting processes.

[0144] If the ambient light controller determines that the status information command is 3, then the ambient light effect is the third effect. The third effect will be described below based on the timing diagram of the third effect shown in Figure 5. It should be noted that Figure 5 is a grayscale image; the original image shows red LED beads.

[0145] As shown in Figure 5, in the third lighting effect, LED beads numbered 1-39 are set to red (RGB value 255, 0, 0), the interval between each action is 40ms, and the number of frames for the third lighting effect is 51 frames.

[0146] The aforementioned third lighting effect can achieve the following visual effect: the driver observes that the LED bead corresponding to the center area of ​​the steering wheel (in this embodiment, the corresponding LED bead is number 20) lights up first, and then extends to both sides of the driver's cab; when the brightness of all LED beads reaches the set maximum value (in the third lighting effect of this embodiment, the maximum brightness value is 31), the brightness gradually decreases to 0, forming a fading effect.

[0147] If the ambient light controller determines that the status information command is 4, then the ambient light effect is the fourth effect. The fourth effect will be described below based on the timing diagram of the fourth effect shown in Figure 6. It should be noted that Figure 6 is a grayscale image; the original image shows red LED beads.

[0148] As shown in Figure 6, in the fourth lighting effect, LED beads numbered 1-39 are set to red (RGB value 255, 0, 0), the interval between each action is 20ms, and the number of frames for the fourth lighting effect is 43 frames.

[0149] The aforementioned fourth lighting effect achieves the following visual effect: LED beads numbered 1-39 gradually brighten from dark (brightness gradually increases), and after reaching a set maximum brightness value (in this embodiment, the maximum brightness value is 31), they gradually dim again. This process is repeated twice, meaning the fourth lighting effect includes three of the above lighting effect processes.

[0150] If the ambient light controller determines that the status information command is valued at 5, then the ambient light effect is the fifth effect. The fifth effect will be described below based on the timing diagram shown in Figure 7. It should be noted that Figure 7 is a grayscale image; the original image shows red LED beads.

[0151] As shown in Figure 7, in the fifth lighting effect, LED beads numbered 1-39 are set to red (RGB value 255, 0, 0), the interval between each action is 40ms, and the number of frames for the fifth lighting effect is 22 frames.

[0152] The aforementioned fifth lighting effect can achieve the following visual effect: LED beads numbered 1-39 start from dark (i.e., lower brightness) and gradually brighten at a faster speed; when the brightness of all LED beads reaches the set maximum value (in the fifth lighting effect of this embodiment, the maximum brightness value is 31), they gradually dim at a slower speed until the brightness is 0.

[0153] The ambient lighting module controls each LED to execute the ambient lighting effect indicated by the lighting effect control signal. Specifically, if the ambient lighting controller determines the status information instruction value to be 0, the ambient lighting effect is not executed; if the ambient lighting controller determines the status information instruction value to be 1, the LEDs are controlled to execute the first lighting effect once; if the ambient lighting controller determines the status information instruction value to be 2, the LEDs are controlled to execute the second lighting effect once; if the ambient lighting controller determines the status information instruction value to be 3, the LEDs are controlled to execute the third lighting effect once; if the ambient lighting controller determines the status information instruction value to be 4, the LEDs are controlled to execute the fourth lighting effect once; if the ambient lighting controller determines the status information instruction value to be 5, the execution time of the fifth lighting effect is determined based on the duration of the lighting effect control signal, and the LEDs are controlled to execute the fifth lighting effect. For example, if the execution time of the fifth lighting effect is greater than the time determined by the number of action frames of the fifth lighting effect, the LEDs will cycle through the fifth lighting effect. In this way, if the light effect control signal continues to exist, it indicates that the autonomous driving system can no longer control the vehicle's autonomous driving, but the driver has not taken over the control of the vehicle; therefore, the fifth light effect is continuously executed to send a prompt message to the driver, thereby prompting the driver to take over the control of the vehicle and reducing the risk of a safety accident.

[0154] The autonomous driving status prompting method provided in this application determines a status information instruction based on the status of the autonomous driving system. This status information instruction indicates the ambient lighting effect. The ambient lighting controller generates and sends the status information instruction to control the ambient lighting to execute its effect. Compared to prompts via the instrument panel or central control screen, ambient lighting effect prompts are more intuitive and eye-catching for the driver, allowing them to quickly identify the current status of the vehicle's autonomous driving system and adjust their driving accordingly. For example, when the autonomous driving system is in a takeover request state, the ambient lighting executes its fifth effect. By observing the ambient lighting effect, the driver can determine that the autonomous driving system is in a takeover request state, thus taking control of the vehicle and preventing loss of control, thereby improving the safety of the autonomous driving system.

[0155] Furthermore, in this embodiment, different ambient light colors, brightness levels, and intervals between actions are set for different ambient light effects. Specifically, when the system is in an active, risk-free, or low-risk state, the ambient light is blue, and the changes in brightness and the intervals between actions provide the driver with a psychological cue of safety. When the system is in a high-risk or takeover-request state, the ambient light is red, and the changes in brightness and the intervals between actions provide the driver with a psychological cue of warning. Through the visual design of the ambient lights, a more intuitive reminder can be provided to the driver.
