Description

Technical Field

[0001] Embodiments of the present invention relate to the field of autonomous driving safety technology, and specifically to an autonomous driving warning method, device, equipment and storage medium. Background Art

[0002] With the rapid development of the automotive industry, autonomous driving technology is gradually moving from concept to practical application. The implementation of autonomous driving functions relies on a complex array of sensors, algorithms, and electronic control systems, aiming to improve the convenience, safety, and efficiency of autonomous driving. However, there are serious communication barriers when it comes to the interaction between autonomous vehicles and other road users.

[0003] Currently, traditional vehicles primarily communicate driving intent through conventional devices like turn signals, brake lights, and horns. However, autonomous vehicles lack effective means of communicating information during operation or under fault conditions. When a vehicle is in autonomous driving mode, it's difficult for the driver of the vehicle behind to intuitively determine whether the vehicle ahead is being automatically controlled by the system. This can lead to inaccurate decisions when overtaking or following. For example, the driver behind may be unaware of the autonomous vehicle's perception range and response capabilities, leading to misjudgment of safe distance and increased risk of rear-end collisions.

[0004] The problem is even more severe when autonomous vehicles malfunction, such as a system degradation causing a sudden stop or deceleration. Without clear warning signs, drivers of vehicles behind them are unable to detect the abnormality in front of them. Especially at high speeds or in heavy traffic, drivers may not have enough time to react, which can easily lead to a chain reaction and pose a serious threat to road safety.

[0005] Furthermore, as autonomous driving technology continues to evolve, different brands and levels of autonomous driving systems handle faults differently, further complicating information communication. Other road users, including drivers and pedestrians, struggle to understand the various potential behaviors of autonomous vehicles, leading to increased uncertainty in the overall traffic environment. Summary of the Invention

[0042] Figure 3 A structural block diagram of a computer device provided by an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0043] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0044] This embodiment provides an autonomous driving warning method to address the problems in the prior art where autonomous driving vehicles lack an intuitive and effective way to inform other road users of the vehicle's current driving status, resulting in an inability to issue timely and clear warnings to vehicles and pedestrians behind, which affects other drivers' decision-making and road safety, and easily causes traffic accidents.

[0045] An embodiment of the present invention provides an automatic driving warning method, such as Figure 1 As shown, the following steps are included:

[0046] S10. Obtain the status information of the autonomous driving ECU in real time.

[0047] In this embodiment, it is important to understand that the autonomous driving ECU's status information is a key data set reflecting the operating status of the autonomous driving system and is crucial for the vehicle's safe operation and interaction with other road users. This information can be categorized into various categories, including autonomous driving function status, autonomous driving operating mode, and fault diagnosis data.

[0048] Among them, the automatic driving function status information includes activation status identification and steering wheel control status data.

[0049] The autonomous driving operating mode includes autonomous driving level data and the activation status of specific functions.

[0050] Fault diagnosis information includes fault code and type, fault severity and impact range.

[0051] Therefore, in this step, the status information of the autonomous driving ECU obtained in real time includes one or more of the activation status identifier, steering wheel control status data, autonomous driving level data, specific function enablement status, fault code and type, and fault severity and impact range.

[0052] S20. Process the acquired status information of the autonomous driving ECU, and determine whether the vehicle is in the autonomous driving mode based on the processed status information of the autonomous driving ECU. If so, determine whether the vehicle has experienced a fault degradation. If so, determine that the vehicle is in the autonomous driving mode and has experienced a fault degradation.

[0053] In this step, based on the status information of the autonomous driving ECU obtained in the above step S10, the status information of the autonomous driving ECU is decoded according to the preset parsing rules to determine the current driving status of the vehicle.

[0054] Specifically, the logic module is connected to the autonomous driving ECU through a preset vehicle network, and data is exchanged with the autonomous driving ECU based on a preset communication protocol to achieve real-time acquisition of various status information of the autonomous driving ECU.

[0055] Since the status information output by the autonomous driving ECU is encoded in a preset data format and protocol, the logic module needs to decode the received status information of the autonomous driving ECU according to the preset parsing rules to determine the current driving status of the vehicle.

[0056] Determining the current driving state of the vehicle includes: first determining whether the vehicle is in the automatic driving mode based on the status information of the automatic driving ECU after decoding, and if so, determining whether the vehicle has a fault degradation, and if so, determining that the vehicle is in the automatic driving mode and has a fault degradation.

[0057] Therefore, in this step, when it is determined that the vehicle has not experienced fault degradation, it is determined that the vehicle is in automatic driving mode.

[0058] S30. Based on the judgment result, control the rear display module to display the current driving status of the vehicle, and transmit the current driving status of the vehicle to surrounding vehicles through the communication module.

[0059] In this step, the corresponding warning information is issued according to the current driving state of the vehicle determined in step S20.

[0060] Specifically, when the current driving state of the vehicle is determined to be the automatic driving mode by the logic module in step S20, the logic module sends corresponding instructions to the display module and the communication module to control the rear display module to display the current driving state of the vehicle, and transmit the current driving state of the vehicle to surrounding vehicles through the communication module.

[0061] That is, in this step, different warning information is issued according to different driving conditions, so that surrounding or rear vehicles can be informed of the vehicle's current dangerous condition in a timely manner, so that emergency avoidance measures can be taken in advance to avoid rear-end collisions.

[0062] Therefore, the autonomous driving warning method provided in this embodiment accurately determines the vehicle's current driving state by acquiring the status information of the autonomous driving ECU in real time. It then generates corresponding warning information based on the vehicle's current driving state to alert vehicles behind or around it. This allows the vehicle to effectively inform other drivers of its current driving state during autonomous driving, and can also provide necessary warnings in emergency situations. This allows surrounding vehicles to clearly understand the driving state of the vehicle ahead, leading them to be more cautious when following or overtaking, adjusting their speed and distance appropriately, and reducing unnecessary acceleration and deceleration. This improves road traffic efficiency while also reducing the likelihood of traffic accidents.

[0063] As a preferred embodiment, this embodiment optimizes the process of determining whether the vehicle is in automatic driving mode.

[0064] Specifically including: determining whether the automatic driving function is in an activated state;

[0065] If so, determine whether the steering wheel is in the Hands off state;

[0066] If so, it is determined that the vehicle is in autonomous driving mode.

[0067] It can be understood that the activation status flag is used to determine whether the autonomous driving function is enabled. When the vehicle starts the autonomous driving mode, the autonomous driving ECU will set the activation status information to "on". After receiving this information, the logic module determines that the autonomous driving function status is active.

[0068] Steering wheel status data includes whether the steering wheel is in the hands-off state, as well as parameters such as steering angle and torque. This data can be used to determine how well the autonomous driving system is controlling the vehicle's steering. If the steering wheel is in the hands-off state and the angle is stable, the vehicle is traveling in a straight line under the control of the autonomous driving system. Abnormal changes in the angle or torque data may indicate that the autonomous driving system is adjusting the driving direction or that a malfunction has occurred, requiring driver intervention.

[0069] Therefore, when the logic module determines that the steering wheel is in the Hands off state, it determines that the vehicle is in the automatic driving mode.

[0070] As a preferred embodiment, this embodiment optimizes the specific judgment process when the vehicle is in automatic driving mode and fault degradation occurs.

[0071] Specifically including: obtaining the vehicle's current autonomous driving level.

[0072] Determine whether the vehicle's current autonomous driving level has been downgraded based on the vehicle's autonomous driving level when it is in autonomous driving mode.

[0073] If so, it is determined that the vehicle is in autonomous driving mode and a fault degradation has occurred.

[0074] In this embodiment, it should be clarified that the operating mode of the autonomous driving system includes autonomous driving level data and the activation status of specific functions, and this embodiment only identifies and evaluates the autonomous driving level data.

[0075] The autonomous driving level data reflects the vehicle's current autonomous driving level, such as L2 or L3. Autonomous driving systems at different levels differ in functionality and driver dependence. When the autonomous driving ECU indicates the vehicle is at Level 3, it indicates that the vehicle can achieve a higher level of autonomous driving under specific conditions, giving the autonomous driving system greater control over the vehicle. If the level is downgraded to Level 2, the driver will need to participate more fully in driving.

[0076] In this embodiment, when the vehicle is in normal autonomous driving mode, the autonomous driving level is L3. When the vehicle is in autonomous driving mode and a fault degrades, the autonomous driving level is L2.

[0077] Therefore, this step can be understood as: judging whether the autonomous driving level is downgraded based on the current autonomous driving level data of the vehicle obtained; if the current autonomous driving level is L2, then determining that the current autonomous driving level of the vehicle is downgraded, and then determining that the vehicle is in autonomous driving mode and a fault downgrade occurs.

[0078] As a preferred embodiment, this embodiment optimizes the determination process of the specific mode when the vehicle is in the automatic driving mode and a fault degradation occurs.

[0079] Specifically, it includes: determining whether the vehicle is in a parking state. If so, it is determined that the vehicle is in automatic driving mode and a fault occurs, so it is downgraded to parking. Otherwise, it is determined that the vehicle is in automatic driving mode and a fault occurs, so it is downgraded to deceleration.

[0080] This step can be understood as: based on the above determination that the vehicle is in automatic driving mode and a fault occurs and the vehicle's driving status includes automatic driving mode and a fault occurs and the vehicle is degraded to parking and the automatic driving mode and a fault occurs and the vehicle is decelerated.

[0081] The process for determining if a vehicle is in autonomous driving mode and a fault occurs and a downgraded parking is performed includes:

[0082] Determine whether the steering wheel is in the hands-off state for more than a preset time.

[0083] If so, it is determined that the vehicle is in autonomous driving mode and a fault has occurred, so it is degraded to parking.

[0084] This step can be understood as: based on the above-mentioned vehicle being in automatic driving mode and a fault is caused for downgrade determination, when the steering wheel is in the Hands off state for more than a preset time, it is determined that the vehicle is in automatic driving mode and a fault is caused for downgrade parking.

[0085] In this embodiment, the preset time can be set according to needs and is not limited in this embodiment.

[0086] Preferably, the preset time can be set to 8S-15S.

[0087] The process for determining whether a vehicle is in autonomous driving mode and decelerates due to a fault is as follows:

[0088] Determine whether the vehicle speed is gradually decreasing.

[0089] If so, it is determined that the vehicle is in automatic driving mode and a fault has occurred, so the vehicle is decelerated.

[0090] This step can be understood as: based on the above-mentioned fact that the vehicle is in automatic driving mode and a fault occurs and a downgrade is determined, the current speed of the vehicle is obtained in real time to determine whether the speed is gradually decreasing. If so, it is determined that the vehicle is in automatic driving mode and a fault occurs and a downgrade is performed.

[0091] Therefore, the current driving status of the vehicle provided in this embodiment includes automatic driving mode, automatic driving mode with deceleration due to a fault, and automatic driving mode with degrading to parking due to a fault.

[0092] In this embodiment, the specific implementation scheme of controlling the rear display module to display the current driving status of the vehicle according to the judgment result and transmitting the current driving status of the vehicle to surrounding vehicles through the communication module is optimized.

[0093] For example, when the logic module determines that the vehicle is in autonomous driving mode, it controls the display module at the rear of the vehicle to display words such as "Autonomous Driving" or "Currently in Autonomous Driving." This allows the driver behind to clearly understand the status of the vehicle ahead from a distance, thereby recognizing the unique control methods of the vehicle ahead. This leads to greater caution when following or overtaking, adjusting speed and distance appropriately, reducing unnecessary acceleration and deceleration, and improving traffic efficiency. The display module features high brightness and excellent visibility, ensuring clear information in a variety of lighting conditions, whether in bright daylight or dark nighttime, effectively conveying warning messages.

[0094] At the same time, the system controls the V2X communication module to transmit status information such as "in autonomous driving mode," "autonomous driving in progress," or "this vehicle is currently autonomous driving" to surrounding vehicles. This allows surrounding vehicles to obtain information about the vehicle ahead in advance. Based on this information, they can plan their routes in advance, avoiding dangerous driving behaviors caused by not being able to observe the vehicle ahead. Furthermore, for vehicles equipped with automated driving assistance systems, this information can directly interact with their own systems to implement automatic deceleration, avoidance maneuvers, and other actions, further improving driving safety and automation.

[0095] When the logic module determines that the vehicle is in autonomous driving mode and a fault has occurred, it controls the display module at the rear of the vehicle to display words such as "Emergency Stop" or "Autonomous Driving Failure Degraded Stop" to enable the driver behind to clearly understand the status of the vehicle ahead from a distance. For example, when seeing "Emergency Stop" or "Autonomous Driving Failure Degraded Stop", the driver behind can be aware of the special handling method of the vehicle ahead and will be more cautious when following or overtaking. They will adjust their speed and distance appropriately, reduce unnecessary acceleration and deceleration, and improve road traffic efficiency. When encountering the "Emergency Stop" or "Autonomous Driving Failure Degraded Stop" prompt, the driver can take timely braking or evasive measures to avoid a collision.

[0096] At the same time, the system controls the V2X communication module to transmit information about situations such as "emergency stop" or "autonomous driving failure-degraded stop" to surrounding vehicles, allowing them to obtain information about the vehicle ahead in advance. This information allows them to plan their routes in advance, avoiding dangerous driving behaviors caused by not being able to observe the vehicle ahead. Furthermore, for vehicles equipped with automated driving assistance systems, this information can directly interact with their own systems, enabling automatic deceleration and avoidance maneuvers, further improving driving safety and automation.

[0097] Furthermore, when the logic module determines that the vehicle is in autonomous driving mode and a fault has occurred, it also activates the rear hazard lights, alerting vehicles behind to the danger ahead. Drivers behind can brake in advance to avoid a rear-end collision after seeing the hazard lights and receiving the warning message.

[0098] When the logic module determines that the vehicle is in autonomous driving mode and a fault has occurred, decelerating, the display module at the rear of the vehicle is controlled to display words such as "Autonomous Driving Fault Slowing Down," "Slowing Down," or "Slowing Down, Please Keep Distance," allowing the driver behind to clearly understand the status of the vehicle ahead from a distance. For example, when seeing "Autonomous Driving Fault Slowing Down," "Slowing Down," or "Slowing Down, Please Keep Distance," the driver behind can take timely braking or evasive measures to avoid a collision.

[0099] At the same time, the system controls the V2X communication module to transmit status information such as "Autonomous Driving Failure Slowing Down," "Decelerating," or "Slowing Down, Please Keep Your Distance" to surrounding vehicles, allowing them to obtain information about the vehicle ahead. This information allows them to plan their routes in advance, avoiding dangerous driving behaviors caused by not being able to observe the vehicle ahead. Furthermore, for vehicles equipped with automated driving assistance systems, this information can directly interact with their own systems, enabling automated deceleration and avoidance maneuvers, further enhancing driving safety and automation.

[0100] Furthermore, when the logic module determines that the vehicle is in autonomous driving mode and a fault has occurred, decelerating the vehicle, it also activates the rear hazard lights to alert surrounding vehicles that the vehicle ahead is decelerating and to maintain a safe distance and be prepared for any potential collisions. This prevents collisions caused by vehicles behind them not noticing the vehicle ahead's deceleration in time.

[0101] In some optional embodiments, the present invention also discloses an automatic driving warning device.

[0102] This embodiment discloses an automatic driving warning device, such as Figure 2As shown, it includes a display module 100 , a communication module 200 and a logic module 300 , and both the display module 100 and the communication module 200 are communicatively connected to the logic module 300 .

[0103] Among them, the logic module 300 is used to obtain the status information of the automatic driving ECU in real time, judge the current driving status of the vehicle based on the obtained status information of the automatic driving ECU, and send the judgment result to the display module 100 and the communication module 200.

[0104] In this embodiment, the logic module 300 acquires, analyzes and processes the status information of the autonomous driving ECU, and determines the current driving status of the vehicle based on the status information of the autonomous driving ECU. For details, refer to the implementation process of the above-mentioned autonomous driving warning method, which will not be repeated in this embodiment.

[0105] The display module 100 is used to display the current driving status of the vehicle determined by the logic module 300 to the vehicle behind.

[0106] In this embodiment, the display module 100 is an LED display screen, which is set at the rear of the vehicle. The content displayed is set autonomously based on the judgment result of the logic module 300.

[0107] The communication module 200 is used to transmit the current driving status of the vehicle determined by the logic module 300 to surrounding vehicles.

[0108] In this embodiment, the communication module 200 adopts V2X communication, and the content it transmits is independently set based on the judgment result of the logic module 300.

[0109] Therefore, the automatic driving warning device provided in this embodiment uses the logic module 300 to obtain the status information of the automatic driving ECU in real time, accurately determine the vehicle's current driving state, generate corresponding warning information based on the vehicle's current driving state, and issue warnings to surrounding vehicles through the display module 100 and the communication module 200. This allows the vehicle to effectively inform other drivers of its current driving state during automatic driving, and can also provide necessary warnings in emergency situations. This allows surrounding vehicles to clearly understand the driving state of the preceding vehicle, allowing them to be more cautious when following or overtaking, reasonably adjusting their speed and distance, and reducing unnecessary acceleration and deceleration. This improves road traffic efficiency while also reducing the probability of traffic accidents.
