[0051] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] With the development of technologies such as artificial intelligence, the autonomous driving function of vehicles has been promoted.

[0054] The following levels of autonomous driving are distinguished based on the capabilities of the vehicle's driving system and the driver's role in the vehicle's driving process:

[0055] Level 0 (L0, also known as no automation): There is no autonomous driving function. The driver controls the vehicle throughout the entire process and is fully responsible for all operations of the vehicle, including acceleration, braking, steering, etc.

[0056] Level 1 (L1, also known as driving 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 speed or direction of the vehicle, but the driver must be ready to take over control at any time.

[0057] Level 2 (L2, also known as partial automation): The vehicle is able to control acceleration, braking and steering at the same time, but the driver must monitor the driving environment at all times and be ready to take over at any time. This level of autonomous driving system is often called "semi-autonomous driving."

[0058] Level 3 (L3, also known as conditional automation): The vehicle is able to fully control driving tasks under certain conditions, including acceleration, braking, and steering. Under these conditions, the driver does not have to monitor the environment at all times, but must be able to take over control in a timely manner when the system requests it.

[0059] Level 4 (L4, also known as high automation): The vehicle is able to fully control 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 is able to safely handle driving tasks.

[0060] Level 5 (L5, also known as full automation): The vehicle can drive fully autonomously in all road and environmental conditions without any driver intervention. This level of autonomous driving system is able to safely operate the vehicle in all situations.

[0061] From the above classification of autonomous driving levels, it can be seen that for a Level 3 autonomous driving system, the driver is required to immediately take over control of the vehicle when the autonomous driving cannot safely control the vehicle; and this requires the vehicle to send a prompt message to the driver so that the driver can know the current status of the autonomous driving system.

[0062] In one example, the status of the autonomous driving system is indicated to the driver via a warning light on the vehicle's dashboard.

[0063] Alternatively, the driver may be prompted through a text message displayed on the central control screen, for example, the displayed text message may be "autopilot activated", "please take over immediately", etc.

[0064] However, the above-mentioned method of issuing prompt information is not eye-catching and intuitive enough, resulting in the user being unable to promptly learn the status of the autonomous driving, resulting in the user being unable to promptly adjust their driving behavior, and there is a risk of causing a safety accident.

[0065] The method for prompting the automatic driving status provided in this application is intended to solve the above technical problems of the prior art.

[0066] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0067] Figure 1 Schematic diagram of the process of the automatic driving status prompt method provided in this application Figure 1 ,like Figure 1 As shown, the method is applied to an ambient light controller in a vehicle, and an ambient light is provided in a main driving area inside the vehicle. The method comprises:

[0068] S101. Receive an ambient light function switch signal sent by a driving information host in a vehicle, and receive a status information instruction sent by a 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.

[0069] For example, the execution subject of the embodiment of the present application may be an electronic device, or a server, or a terminal device, or other devices or equipment that can execute the solution of the embodiment, and this is not limited. This embodiment is introduced with the execution subject being an atmosphere light controller.

[0070] The ambient light controller receives the ambient light function switch signal sent by the display head unit (DHU, also known as the driving information and entertainment host) in the vehicle. The ambient light controller and the driving information host can be connected via the Flexray bus; the Flexray bus is a time-triggered dual-channel bus that can transmit data, and the data transmission rate of a single channel is 10Mbps.

[0071] The ambient light function switch signal (AmbLiAll) represents the ambient light state of the ambient light at the current moment; wherein the ambient light state may include an on state and an off state.

[0072] The ambient light controller also receives status information instructions sent by the central processing unit (Autonomous Driving MainComputer, ADMC, also known as the autonomous driving central main processor) in the vehicle. The ambient light controller and the central processing unit can be connected via a Flexray bus.

[0073] The vehicle is also equipped with a body domain control unit (CEM, also known as a central electronic module), and the ambient light controller and the body domain control unit can be connected via a bus.

[0074] The CPU determines the different values ​​contained in the status information instruction (AD4AmbLiReqGroup.AmbLiReq) according to the different states of the autonomous driving system; the states of the autonomous driving system include the following:

[0075] The first is the system activation state, which indicates that the vehicle's automatic driving system has been activated and is controlling the vehicle's driving.

[0076] The second 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.

[0077] The third is a low-risk state, which indicates that there are some risks in the current driving environment, but the autonomous driving system can control these risks and can fully and safely control the vehicle.

[0078] The fourth is a high-risk state. In this state, the risks in the current driving environment may exceed the processing capabilities of the autonomous driving system, and the autonomous driving system may not be able to safely control the vehicle.

[0079] The fifth type is the request to take over state. In this state, the risk in the current driving environment is determined to exceed the processing capacity of the autonomous driving system. The autonomous driving system cannot safely control the vehicle, and the driver needs to take over the control of the vehicle immediately.

[0080] Different values ​​in the status information command indicate different lighting effects of the ambient light. For example, the ambient light may include multiple light emitting diodes (LEDs), also known as LED lamp beads; the lighting effect of the ambient light may include the color of the LED lamp beads, the brightness of the LED lamp beads, and the flashing cycle of the LED lamp beads.

[0081] S102. If it is determined to start the ambient light prompt mode 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; wherein 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 automatic driving status.

[0082] Exemplarily, the ambient light controller determines whether to start the ambient light prompt mode according to the ambient light function switch signal and the vehicle state of the vehicle.

[0083] For example, if the ambient light state indicated by the ambient light function switch signal is turned on, and the vehicle state is consistent with the preset vehicle state, the body domain control unit determines to start the ambient light prompt mode. For example, the preset vehicle state can be a user use mode, wherein the user use mode indicates that the vehicle is in a state where the user is driving.

[0084] By setting the judgment conditions for starting the ambient light prompt mode, it helps to ensure that the ambient light prompting the status of the autonomous driving system is only activated under appropriate circumstances, reducing the possibility of erroneous triggering of the ambient light due to misjudgment of vehicle status or user intention, avoiding unnecessary interference to the driver, and reducing energy consumption.

[0085] It is worth noting that in this embodiment, the ambient light is set in the main driving area inside the vehicle, that is, the ambient light related to the ambient light prompt mode is set in the main driving area. The advantage of this setting is that the prompt range of the ambient light lighting effect is limited to the range directly facing the driver's eyes, and the driver can perceive the lighting effect of the ambient light only through the peripheral light, that is, the ambient light dynamic effect light language; the driver can obtain the status of the automatic driving system more quickly, and then adjust his own driving behavior, for example, actively take over the control of the vehicle; thereby improving the user experience and the safety of the automatic driving system.

[0086] However, this embodiment does not limit the setting areas of other ambient lights in the vehicle, that is, it does not limit the setting areas of ambient lights that are not related to the ambient light prompt mode; for example, ambient lights that are not related to the ambient light prompt mode can be set on the inside of the vehicle's door, the roof of the vehicle, and the seat area of ​​the vehicle, etc.

[0087] After the ambient light controller determines to start the ambient light prompt mode, the ambient light controller generates and sends a status information instruction.

[0088] The Ambient Lights Module (ALM) controls the ambient light to execute the ambient light effect according to the ambient light effect indicated in the received status information command. The ambient light controller can convert the status information command into a lighting effect control signal and transmit the lighting effect control signal to the ambient light module; the ambient light module controls the ambient light to execute the ambient light effect according to the lighting effect control signal.

[0089] By observing the lighting effects of the ambient light, the driver can identify the current status of the vehicle's automatic driving system, and then adjust his or her own driving state according to the status of the automatic driving system, that is, the automatic driving state, to ensure driving safety.

[0090] For example, the driver can understand the correspondence between the lighting effects of the ambient light and the status of the autonomous driving system by reading the user manual, instruction manual, or watching the vehicle's simulation demonstration video; thus, the driver can know the current status of the vehicle's autonomous driving system by observing the lighting effects of the ambient light.

[0091] In the method for prompting the state of the automatic driving provided in the embodiment of the present application, the central processing unit determines and sends a state information instruction according to the state of the automatic driving system, wherein the state information instruction indicates the lighting effect of the ambient light; the ambient light controller generates and sends a state information instruction to control the ambient light set in the vehicle to execute the lighting effect of the ambient light. Compared with the prompt through the instrument panel or the central control screen, the lighting effect prompt of the ambient light is more intuitive and eye-catching for the driver. The driver can quickly identify the current state of the vehicle's automatic driving system and then adjust his own driving state, thereby improving the safety of the automatic driving system and reducing safety risks.

[0092] In addition, in the embodiment of the present application, the ambient light related to the ambient light prompt mode is set in the main driving area. In this way, the prompt range of the ambient light lighting effect is limited to the range directly facing the driver's eyes. The driver can perceive the lighting effect of the ambient light only through the peripheral vision, that is, the ambient light dynamic effect light language. The driver can more quickly obtain the status of the automatic driving system and then adjust his own driving behavior, for example, actively take over the control of the vehicle; thereby improving the user experience and the safety of the automatic driving system.

[0093] Figure 2 Schematic diagram of the process of the automatic driving status prompt method provided in this application Figure 2 ,like Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, a method for prompting the state of automatic driving is described in detail, and the method includes:

[0094] S201. Receive an ambient light function switch signal sent by a driving information host in the vehicle, and receive a status information instruction sent by a central processing unit in the vehicle; wherein the ambient light function switch signal represents the ambient light state at the current moment; the status information instruction is determined based on the autonomous driving state of the vehicle's autonomous driving system at the current moment, and the status information instruction indicates the lighting effect of the ambient light.

[0095] For example, the execution subject of the embodiment of the present application may be an electronic device, or a server, or a terminal device, or other devices or equipment that can execute the solution of the embodiment, and this is not limited. This embodiment is introduced with the execution subject being an atmosphere light controller.

[0096] For the specific process of this step, please refer to the process in step S101, which will not be repeated here.

[0097] S202. If it is determined to start the ambient light prompt mode 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; wherein 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 automatic driving status.

[0098] In one example, the vehicle state includes vehicle mode information and vehicle use mode information, wherein the vehicle mode information represents the factory state of the vehicle, and the vehicle use mode information represents the running state of the vehicle; in step S202, "if it is determined to start the ambient light prompt mode according to the ambient light function switch signal and the vehicle state of the vehicle", includes the following process:

[0099] If the atmosphere light prompt mode is determined to be started based on the atmosphere light function switch signal and the vehicle status of the vehicle, including: if it is determined that the vehicle factory status indicated by the vehicle mode information is the user usage status, and the vehicle operation status indicated by the vehicle usage mode information is the power-on mode status, and the atmosphere light status indicated by the atmosphere light function switch signal is the on status, then it is determined to start the atmosphere light prompt mode.

[0100] In one example, when the value of the ambient light function switch signal is 1, the ambient light state of the ambient light at the current moment is the on state.

[0101] When the value of the ambient light function switch signal is 0, the ambient light state of the ambient light at the current moment is the off state.

[0102] Exemplarily, the ambient light controller determines the vehicle status; for example, the vehicle status includes vehicle mode information and vehicle use mode information. The vehicle mode information represents the factory status of the vehicle, and the vehicle mode information includes production mode, transportation mode and normal mode (also called normal mode); among them, the production mode represents that the vehicle is in the factory production process; the transportation mode represents the mode of the vehicle in the transportation process after the factory production is completed; the normal mode represents the mode of the vehicle in the user's use state after the vehicle is delivered to the user.

[0103] The vehicle usage mode information represents the operating status of the vehicle. The vehicle usage mode information includes power-on mode (also called driving mode), sleep mode, etc. The power-on mode represents that the vehicle's high-voltage battery is in a power-supply state, and the sleep mode represents that the vehicle's high-voltage battery is in a non-power-supply state.

[0104] The driving information host determines and sends an ambient light function switch signal to the ambient light controller according to the state of the ambient light. For example, if the state of the ambient light is on, the value of the ambient light function switch signal is 1; if the state of the ambient light is off, the value of the ambient light function switch signal is 0.

[0105] If the ambient light controller determines that the vehicle mode information includes the normal mode (i.e., the vehicle is in use by the user), and the vehicle use mode information includes the power-on mode and the value of the ambient light function switch signal is 1, then the ambient light prompt mode is determined to be started, and then the subsequent ambient light lighting effect control is entered. Otherwise, the ambient light prompt mode is not started.

[0106] In one example, the autonomous driving state is determined based on the vehicle's driving environment information.

[0107] The state information instruction is determined based on the autonomous driving state and a first preset mapping relationship, and the first preset mapping relationship is the correspondence between the autonomous driving state and the value of the state information instruction.

[0108] Exemplarily, first, the driving environment information of the vehicle is collected through sensors deployed in the vehicle (e.g., laser radar, camera). For example, the driving environment information includes: other vehicle information, pedestrian information, traffic signal information, road condition information, road sign information, and weather condition information. The sensor transmits the collected driving environment information to the central processor.

[0109] The central processing unit determines the state of the vehicle's automatic driving system based on the received driving environment information of the vehicle, and then the central processing unit generates and sends a state information instruction. For example, this can be achieved through the following two processes.

[0110] First, there is a corresponding relationship between the state of the automatic driving system and the driving environment information. For example, according to the information included in the driving environment information, the driving environment information is divided into the first level, the second level, the third level and the fourth level; among them, if it is determined that the driving environment information belongs to the first level, the corresponding automatic driving system is in a risk-free state; if it is determined that the driving environment information belongs to the second level, the corresponding automatic driving system is in a low-risk state; if it is determined that the driving environment information belongs to the third level, the corresponding automatic driving system is in a high-risk state; if it is determined that the driving environment information belongs to the fourth level, the corresponding automatic driving system is in a request to take over state.

[0111] For example, the levels of driving environment information can be divided as follows.

[0112] The first level conditions can be:

[0113] Other vehicle information meets the following criteria: maintaining a safe distance, driving steadily, and no signs of sudden lane changes or sudden braking; pedestrian information meets the following criteria: no pedestrians are in the vehicle's expected path, or pedestrian behavior is predictable and obeys traffic rules. Traffic signal information meets the following criteria: all traffic signals and signs are clearly identified, and there are no conflicting or unclear signals. Road condition information meets the following criteria: the road surface is dry and flat, without obstacles or hazards (for example, potholes, gravel, etc.). Road sign information meets the following criteria: all road signs are clearly visible and consistent with the navigation system information. Weather condition information meets the following criteria: clear or slightly cloudy, visibility is high, and there is no rain, snow or fog that affects vision.

[0114] The second level conditions can be:

[0115] Other vehicle information meets the following criteria: Vehicles may be traveling nearby, but their speed and behavior are stable, and the automated driving system can predict and adapt to their behavior. Pedestrian information meets the following criteria: Pedestrians are near the vehicle, but there is enough time and space to avoid or stop. Traffic signal information meets the following criteria: Traffic signals may have some ambiguity, but the automated driving system can verify it through other sensors or navigation data. Road condition information meets the following criteria: The road surface may be slightly slippery or have a few obstacles, but the automated driving system can identify and safely circumvent them. Road sign information meets the following criteria: Some road signs may not be clear enough, but the system can compensate for them through other data sources. Weather condition information meets the following criteria: Light rain, snow or fog, but it does not affect the automated driving system's sensor performance and visibility.

[0116] The third level conditions can be:

[0117] Other vehicle information meets the following criteria: Vehicle behavior is erratic 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 behave suddenly, giving the automated driving system limited time to react. Traffic signal information meets the following criteria: Traffic signals are damaged, obscured, 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, affecting the stability and handling of the vehicle. 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 seriously affect sensor performance and the driver's line of sight.

[0118] The fourth level conditions can be:

[0119] Road condition information meets the following criteria: road conditions are poor, for example, when encountering severe road condition problems such as deep water, snow, ice or other conditions that make vehicle control difficult. Other vehicle information or pedestrian information meets the following criteria: when the system detects an imminent collision or other emergency situation, and automatic emergency braking or other avoidance measures cannot avoid the danger; or, such as traffic congestion, dense pedestrian areas or traffic control caused by special events. Weather condition information meets the following criteria: when environmental conditions change rapidly, such as sudden heavy rain, fog or storms, beyond the system's response capabilities. System failure or abnormality: The autonomous driving system software or hardware fails, or the system behavior is abnormal, and safe driving cannot be guaranteed.

[0120] Secondly, according to the first preset mapping relationship, the value of the status information instruction can be determined by the status of the autonomous driving system.

[0121] For example, if the state of the autonomous driving system is determined to be the system activation state, the value of the state information instruction is 1; if the state of the autonomous driving system is determined to be a risk-free state, the value of the state information instruction is 2; if the state of the autonomous driving system is determined to be a low-risk state, the value of the state information instruction is 3; if the state of the autonomous driving system is determined to be a high-risk state, the value of the state information instruction is 4; if the state of the autonomous driving system is determined to be a request to take over state, the value of the state information instruction is 5; if the state of the autonomous driving system is determined to be other states, that is, the current state of the vehicle's autonomous driving system does not belong to any of the above states, then the value of the state information instruction is 0.

[0122] In one example, the autonomous driving state is obtained by inputting the vehicle's driving environment information into a preset model for identification.

[0123] Alternatively, the autonomous driving state is determined based on the vehicle's driving environment information and a second preset mapping relationship, and the second preset mapping relationship is the correspondence between the vehicle's driving environment information and the autonomous driving state.

[0124] Exemplarily, 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 state of the autonomous driving system based on the correspondence between the driving environment information and the state of the autonomous driving system, that is, the second preset mapping relationship.

[0125] For example, the recognition and processing of driving environment information by the preset model can be achieved through the following process; wherein the driving environment information includes other vehicle information, pedestrian information, traffic signal information, road condition information, road sign information and weather condition information.

[0126] The preset model processes the driving environment information to obtain characteristic values ​​of other vehicle information, pedestrian information, traffic signal information, road condition information, road sign information and weather condition information.

[0127] The preset model assigns different weight values ​​to each of the above characteristic values ​​according to the degree of influence of other vehicle information characteristic values, pedestrian information characteristic values, traffic signal information characteristic values, road condition information characteristic values, road sign information characteristic values ​​and weather condition information characteristic values ​​on driving safety, and then obtains the characteristic weight values ​​of other vehicle information, pedestrian information, traffic signal information, road condition information, road sign information and weather condition information; wherein, the allocation of the above weight values ​​can be determined based on expert experience, statistical analysis or machine learning models.

[0128] The comprehensive risk value is determined based on the characteristic weight values ​​of other vehicle information, pedestrian information, traffic signal information, road condition information, road sign information, and weather condition information. The comprehensive risk value can be obtained by multiplying each characteristic value with its corresponding characteristic weight value (for example, the characteristic weight value corresponding to the characteristic value of other vehicle information is the characteristic weight value of other vehicle information, and then adding them together; that is, the comprehensive risk value is calculated by weighting.

[0129] According to the value of the comprehensive risk value, the state of the autonomous driving system is determined; for example, the value of the comprehensive risk value is determined within a preset threshold, and then 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 request for takeover state. The preset threshold can be determined through historical data analysis, expert opinions, or test data.

[0130] S203: The value of the status information instruction corresponds to the lighting effect of the ambient light.

[0131] For example, in the ambient light prompt mode, the lighting effect of the ambient light is determined according to the value of the status information instruction. In this embodiment, the ambient light includes 100 LED lamp beads, which are numbered 1-100 (positive integers) from left to right with reference to the vehicle's cab instrument panel; among them, the LED lamp beads corresponding to the main driving area are numbered 1-39.

[0132] The atmosphere light controller sends a lighting effect control signal to the atmosphere light 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 the LED lamp bead corresponding to each number; wherein, the control information includes: the number of the LED lamp bead, the color of the LED lamp bead, the brightness of the LED lamp bead, and the interval duration of each action (also called a cycle); wherein, each LED lamp bead number corresponds to two LED lamp beads, for example, they can be called the first lamp bead and the second lamp bead respectively. The correspondence between the number of each LED lamp bead and the LED lamp bead can be found in the table below. For the sake of brevity, only the correspondence between the numbers of some LED lamp beads and the LED lamp beads is listed here, which does not mean that this solution only includes the following LED lamp beads.

[0133]

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

[0135] As shown in the following table, the LED lamp bead is numbered 404, the color of the first lamp bead is controlled to be white (RGB value is 255, 255, 255), the brightness value is 31, and the color of the second lamp bead is controlled to be red (RGB value is 255, 0, 0), and the brightness value is 20; the content of the control message expressed in hexadecimal is: ID=0x404; FF 00 00 14 FF FF FF 1F.

[0136]

[0137] The lighting effects of each atmosphere light are described in detail below.

[0138] If the ambient light controller determines that the value of the status information instruction is 0, the ambient light lighting effect is not executed; when the ambient light lighting effect is not executed, the ambient light maintains the original lighting effect. For example, if the color of the ambient light set by the driver is yellow, the original lighting effect of the ambient light is yellow. When the ambient light prompt mode is activated, if the ambient light lighting effect indicates that the lighting effect is not executed, the ambient light maintains the yellow setting set by the driver.

[0139] If the ambient light controller determines that the value of the status information instruction is 1, the ambient light lighting effect is the first lighting effect. Figure 3 The first lighting effect timing diagram shown introduces the first lighting effect.

[0140] exist Figure 3 In the figure, from left to right, the LED lamp beads numbered 1-39 are set to blue (RGB values ​​are 40, 100, 255), and the values ​​in the table represent the brightness values ​​(empty tables represent the brightness of the corresponding LED is 0); from top to bottom, the color and brightness of the LED lamp beads numbered 1-39 in each frame (that is, in each action); for example, in the 13th action (corresponding to Figure 3 In step 13 of the example, the brightness of LED beads numbered 3-37 is 31, and the brightness of LED beads numbered 1-2 and 38-39 is 0. In the first lighting effect, the interval between each frame (i.e., the interval between each action) is 40ms, and the number of action frames is 51.

[0141] The first lighting effect mentioned above can achieve the following visual effect: the driver observes that the LED lamp beads corresponding to the middle area of ​​the steering wheel (in this embodiment, the corresponding LED lamp beads are numbered 20) light up first, and then expand to both sides of the cab and light up; when the brightness of all LED lamp beads reaches the set maximum value (in the first lighting effect of this embodiment, the maximum brightness is 31), the brightness of each LED lamp bead gradually decreases to 0, forming a gradually extinguishing effect. Among them, the other LED lamp beads (numbered 40-100) on the cab instrument panel are not controlled by the ambient light prompt mode and still display the color set by the user.

[0142] If the ambient light controller determines that the value of the state information instruction is 2, the ambient light lighting effect is the second lighting effect. Figure 4 The second lighting effect timing diagram shown is used to introduce the second lighting effect.

[0143] according to Figure 4 , indicating that in the second lighting effect, the LED beads numbered 1-39 are set to blue (RGB values ​​are 40, 100, 255); the interval between each action is 20ms, and the number of action frames of the second lighting effect is 29 frames.

[0144] The second lighting effect can achieve the following visual effect: the LED lamp beads numbered 1-39 gradually become brighter (the brightness gradually increases), and after the brightness reaches the set maximum value (in the second lighting effect of this embodiment, the maximum brightness is 31), it gradually becomes darker. The above process is repeated once, that is, the second lighting effect includes the above lighting effect process twice.

[0145] If the ambient light controller determines that the value of the state information instruction is 3, the ambient light lighting effect is the third lighting effect. Figure 5 The third lighting effect timing diagram shown introduces the third lighting effect.

[0146] according to Figure 5 , indicating that in the third lighting effect, the LED beads numbered 1-39 are set to red (RGB values ​​are 255, 0, 0), the interval between each action is 40ms, and the number of action frames of the third lighting effect is 51 frames.

[0147] The above-mentioned third lighting effect can achieve the following visual effect: the driver observes that the LED lamp beads corresponding to the middle area of ​​the steering wheel (in this embodiment, the corresponding LED lamp beads are numbered 20) light up first, and then expand to both sides of the cab and light up; when the brightness of all LED lamp beads reaches the set maximum value (in the third lighting effect of this embodiment, the maximum brightness is 31), the brightness gradually decreases to 0, forming a gradually extinguishing effect.

[0148] If the ambient light controller determines that the value of the state information instruction is 4, the lighting effect of the ambient light is the fourth lighting effect. Figure 6 The fourth lighting effect timing diagram shown introduces the fourth lighting effect.

[0149] according to Figure 6 , indicating that in the fourth lighting effect, the LED beads numbered 1-39 are set to red (RGB values ​​are 255, 0, 0), the interval between each action is 20ms, and the number of action frames of the fourth lighting effect is 43 frames.

[0150] The fourth lighting effect can achieve the following visual effect: the LED lamp beads numbered 1-39 gradually become brighter (gradually increase in brightness), and after the brightness value reaches the set maximum value (in the fourth lighting effect of this embodiment, the maximum brightness value is 31), they gradually become darker. The above process is repeated twice, that is, the fourth lighting effect includes the above lighting effect process three times.

[0151] If the ambient light controller determines that the value of the status information instruction is 5, the lighting effect of the ambient light is the fifth lighting effect. Figure 7 The fifth lighting effect timing diagram shown introduces the fifth lighting effect.

[0152] according to Figure 7 , indicating that in the fifth lighting effect, the LED beads numbered 1-39 are set to red (RGB values ​​are 255, 0, 0), the interval between each action is 40ms, and the number of action frames of the fifth lighting effect is 22 frames.

[0153] The fifth lighting effect mentioned above can achieve the following visual effect: the LED beads numbered 1-39 change from dark (i.e., lower brightness) to brighter 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 is 31), they dim at a slower speed until the brightness is 0.

[0154] The atmosphere light module controls each LED lamp bead to execute the atmosphere light effect according to the atmosphere light effect indicated by the lighting effect control signal. Among them, if the atmosphere light controller determines that the value of the state information instruction is 0, the lighting effect of the atmosphere light is not to execute the lighting effect; if the atmosphere light controller determines that the value of the state information instruction is 1, then each LED lamp bead is controlled to execute the first lighting effect once; if the atmosphere light controller determines that the value of the state information instruction is 2, then each LED lamp bead is controlled to execute the second lighting effect once; if the atmosphere light controller determines that the value of the state information instruction is 3, then each LED lamp bead is controlled to execute the third lighting effect once; if the atmosphere light controller determines that the value of the state information instruction is 4, then each LED lamp bead is controlled to execute the fourth lighting effect once; if the atmosphere light controller determines that the value of the state information instruction is 5, then according to the duration of the lighting effect control signal, the execution time of the fifth lighting effect is determined, and each LED lamp bead is controlled to execute the fifth lighting effect; for example, the duration of the lighting effect control signal is used as the execution time of the fifth lighting effect. 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, then each LED lamp bead will execute the fifth lighting effect cyclically. In this way, if the lighting effect control signal continues to exist, it means that the automatic driving system can no longer control the vehicle's automatic driving, but the driver has not taken over the control of the vehicle; therefore, the fifth lighting effect is continuously executed to send a prompt message to the driver, thereby prompting the driver to take over the control of the vehicle to reduce the risk of safety accidents.

[0155] The method for prompting the state of the automatic driving provided in the embodiment of the present application determines the state information instruction through the state of the automatic driving system, wherein the state information instruction indicates the lighting effect of the atmosphere light; the atmosphere light controller generates and sends the state information instruction to control the atmosphere light to execute the lighting effect of the atmosphere light; compared with the prompt through the instrument panel or the central control screen, the lighting effect prompt of the atmosphere light is more intuitive and eye-catching for the driver, and the driver can quickly identify the current state of the automatic driving system of the vehicle, and then adjust his own driving state. For example, when the state of the automatic driving system is the request to take over state, the atmosphere light executes the fifth lighting effect, and the driver can determine that the state of the automatic driving system is the request to take over state by observing the lighting effect of the atmosphere light, thereby taking over the control of the vehicle and avoiding the vehicle from losing control, thereby improving the safety of the automatic driving system.

[0156] In addition, in the embodiment of the present application, different colors of the atmosphere lights, the brightness of the atmosphere lights, and the interval length of each action are set for different lighting effects of the atmosphere lights. Specifically, when in the system activation state, risk-free state, and low-risk state, the color of the atmosphere light is blue, and the change in the brightness of the atmosphere light and the setting of the interval length of the action can provide the driver with a psychological hint of safety; when in a high-risk state and a request to take over state, the color of the atmosphere light is red, and the change in the brightness of the atmosphere light and the setting of the interval length of the action can provide the driver with a psychological hint of warning. Through the visual design of the atmosphere light, it can serve as a prompt to the driver more intuitively.
