Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle control technology, specifically to a method, device, equipment, and storage medium for long-distance road condition detection. Background Technology
[0002] Current vehicles face the problem of insufficient environmental perception capabilities in high-speed or inclement weather conditions. Specifically, vehicle design often limits the installation location of sensors, resulting in a limited field of view that cannot fully cover the vehicle's surroundings. This limitation may lead to sensors failing to detect distant obstacles or changes in road conditions in a timely manner, especially at high speeds. The effective detection range of traditional sensors (such as cameras and lidar) is significantly reduced in inclement weather conditions (such as heavy fog, heavy rain, and heavy snow) or at night. This short line-of-sight problem makes it difficult for vehicles to obtain sufficient environmental information in a timely manner to make safety decisions. Therefore, vehicles struggle to effectively detect and warn of road conditions at long distances in high-speed or inclement weather conditions, increasing driving risks. Summary of the Invention
[0003] In view of the above problems, embodiments of the present invention provide a method, apparatus, device and storage medium for long-distance road condition detection, which solves the problem that vehicles are unable to effectively detect long-distance road conditions under high-speed or severe weather conditions in the prior art.
[0004] According to one aspect of the present invention, a long-range road condition detection method is provided, wherein a retractable sensor structure is integrated on the top of a vehicle, the retractable sensor structure comprising a retractable rod structure and an environmental perception sensor mounted on the top of the retractable rod structure, the method comprising:
[0005] In response to a long-distance road condition detection command, the retractable sensor structure is controlled to extend from the top of the vehicle, and after the retractable rod structure extends to the target length, the environmental perception sensor is activated to perform long-distance road condition detection.
[0006] According to another aspect of the present invention, a long-range road condition detection device is provided, wherein a retractable sensor structure is integrated on the top of a vehicle. The retractable sensor structure includes a retractable rod structure and an environmental sensing sensor mounted on the top of the retractable rod structure. The device includes:
[0007] The control module is used to respond to long-distance road condition detection commands, control the retractable sensor structure to extend from the top of the vehicle, and activate the environmental perception sensor to perform long-distance road condition detection after the retractable rod structure extends to the target length.
[0008] According to another aspect of the present invention, a long-range road condition detection device is provided, comprising:
[0009] The processor, memory, communication interface, and communication bus are provided, wherein the processor, memory, and communication interface communicate with each other via the communication bus.
[0010] The memory is used to store at least one executable instruction that causes the processor to perform the operation of the long-distance road condition detection method as described above.
[0011] According to another aspect of the present invention, a computer-readable storage medium is provided, the storage medium storing at least one executable instruction that causes a long-range road condition detection device / apparatus to perform the operation of the long-range road condition detection method as described above.
[0012] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof. This increased height significantly expands the sensor's field of view, enabling it to detect road conditions ahead earlier and from a greater distance. It also provides a longer reaction time at high speeds. In adverse weather conditions, such as heavy fog or torrential rain, the sensor can extend to a higher position to avoid some low-altitude interference, improving the effectiveness and accuracy of detection. Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.

[0021] Figure 7 A structural schematic diagram of an embodiment of the vehicle provided by the present invention is shown. Detailed Implementation
[0022] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0023] Figure 1 A flowchart illustrating a first embodiment of the long-range road condition detection method of the present invention is shown. This method can be executed by a domain controller in a vehicle, such as a body domain controller. A retractable sensor structure is integrated on the vehicle roof. The retractable sensor structure includes a retractable rod structure and an environmental perception sensor mounted on top of the retractable rod structure, such as... Figure 1 As shown, the method includes the following steps:
[0024] Step 110: In response to the long-distance road condition detection command, control the retractable sensor structure to extend from the top of the vehicle, and after the retractable rod structure extends to the target length, activate the environmental perception sensor to perform long-distance road condition detection.
[0025] In this embodiment of the invention, when a long-range road condition detection command is received, it means that the vehicle needs to obtain detailed information about the road ahead in order to make better driving decisions. In response to this command, a retractable sensor structure is extended from the top of the vehicle. This process involves extending the retractable pole structure to a target length. After reaching the target length, an environmental perception sensor mounted on top of the pole structure is activated. At this time, the environmental perception sensor begins to perform the long-range road condition detection task, and the long-range road condition information collected by the environmental perception sensor will be fed back to the vehicle's autonomous driving domain controller or other domain controllers.
[0026] Reference Figure 2 The diagram shown is a schematic of a retractable rod structure extending from the top of a vehicle provided by the present invention. An environmental sensing sensor, not shown in the diagram, is installed on the top of the retractable rod structure.
[0027] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof. This increased height significantly expands the sensor's field of view, enabling it to detect road conditions ahead earlier and from a greater distance. It also provides a longer reaction time at high speeds. In adverse weather conditions, such as heavy fog or torrential rain, the sensor can extend to a higher position to avoid some low-altitude interference, improving the effectiveness and accuracy of detection. Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.
[0028] Figure 3 A flowchart of another embodiment of the long-range road condition detection method of the present invention is shown, which can be executed by a domain controller in a vehicle, such as a body domain controller. A retractable sensor structure is integrated on the top of the vehicle. The retractable sensor structure includes a retractable rod structure and an environmental perception sensor mounted on top of the retractable rod structure. The retractable rod structure includes multiple retractable arms. Figure 3 As shown, the method includes the following steps:
[0029] Step 310: In response to the long-distance road condition detection command, identify the current long-distance road condition detection scenario.
[0030] Long-range road condition detection scenarios can include city streets, highways, and mountain roads.
[0031] In this way, vehicle-mounted cameras can capture images of the surrounding environment, and image recognition technology can identify features such as road signs, buildings, and vegetation to determine the vehicle's location. Alternatively, inertial measurement units can be used to detect the vehicle's acceleration and angular velocity, thereby inferring the road's slope and curvature, which is very useful for identifying mountain roads. Or, by monitoring the vehicle's speed, the environment in which the vehicle is located can be inferred. For example, high speed usually indicates that the vehicle is on a highway, while lower speed may indicate that the vehicle is in an urban area.
[0032] In one alternative approach, the long-range road condition detection command is generated when the vehicle's driving data information meets preset driving conditions and / or the vehicle's surrounding environment information meets preset surrounding environment conditions.
[0033] In this embodiment, the generation of long-distance road condition detection commands is triggered based on specific conditions. These conditions can be divided into two categories: vehicle driving data information and vehicle surrounding environment information.
[0034] Driving data includes vehicle characteristics such as speed, acceleration, direction, and driving path. When this driving data meets certain preset conditions (e.g., the vehicle reaches a certain speed or enters a specific driving mode), a long-range road condition detection command is generated. This means that the vehicle needs to perform more detailed road condition detection under certain driving conditions to ensure safety and optimize the driving experience.
[0035] Surrounding environmental information includes features of the environment around the vehicle, such as weather conditions, lighting conditions, obstruction from vehicles ahead, road type, and traffic density. When this environmental information meets preset conditions (e.g., entering complex urban areas or in low visibility conditions), long-range road condition detection commands are also triggered. This ensures that the vehicle obtains sufficient road condition information to make adjustments under different environmental conditions.
[0036] In addition, in response to user touch operations on a designated area of the in-vehicle screen or user voice commands, long-distance road condition detection commands can also be generated.
[0037] Long-distance road condition detection commands can also be generated by other domain controllers (such as the autonomous driving domain controller) and sent to the vehicle domain controller.
[0038] Step 320: Based on the preset mapping relationship between long-distance road condition detection scenarios and telescopic lengths, determine the telescopic length corresponding to the current detection scenario.
[0039] In this embodiment of the invention, a mapping relationship between long-distance road condition detection scenarios and telescopic lengths is pre-defined. This means that telescopic length data required for different scenarios has been stored, so that the appropriate telescopic length can be quickly determined under different circumstances. By querying this pre-defined mapping relationship, the telescopic length corresponding to the current detection scenario can be quickly identified.
[0040] Step 330: Using the determined telescopic length as the target length, generate a telescopic command to control the telescopic sensor structure to extend from the top of the vehicle, and adjust the telescopic arm's extension amount to extend the telescopic rod structure to the target length.
[0041] Once the desired telescopic length is determined, it can be set as the target length, and a corresponding telescopic command can be generated. The telescopic command controls the extension of the retractable sensor structure from the top of the vehicle. By adjusting the length of the telescopic arm, the retractable rod structure is ensured to reach the target length.
[0042] Step 340: After the telescopic pole structure extends to the target length, activate the environmental perception sensor to detect road conditions at a long distance.
[0043] Once the retractable pole successfully extends to the target length, the environmental perception sensors mounted on it are activated. These sensors then begin long-range road condition detection, collecting data to aid the vehicle in route planning, navigation, and other operations. By being elevated to a higher position, the environmental perception sensors gain a wider field of view. This elevated perspective effectively reduces interference from factors such as rain, fog, or obstructions from other vehicles. In this way, the sensors' ability to detect distant targets is significantly enhanced, while their perception of road conditions becomes clearer and more stable.
[0044] Furthermore, when the retractable sensor structure is in operation, the vehicle screen can display the retractable sensor structure's extension and retraction status in real time, and users can adjust the retractable sensor structure's extension and retraction status using controls (such as sliders or buttons) on the touch screen.
[0045] In addition, the telescopic pole structure includes a mechanical limiting structure to restrict its maximum extension length. This design prevents the telescopic pole structure from rising too high under abnormal conditions (such as system failure or misoperation), thereby avoiding potential physical damage or safety hazards.
[0046] With the retractable sensor structure in operation, the extension status of the retractable rod structure is continuously monitored. If the extension length reaches a preset threshold, the control stops further extension to prevent exceeding the safe range. This control method provides additional safety by preventing the retractable rod structure from rising excessively under abnormal circumstances.
[0047] In this embodiment of the invention, the current status of the retractable sensor structure (such as height, whether it is working properly, etc.) can be synchronized in real time to the vehicle's computer or the owner's mobile terminal. The operating status of the retractable sensor structure and its control system can be detected. If any abnormality or malfunction is detected, a timely warning can be issued to the user through the vehicle's screen, allowing the user to quickly take appropriate measures.
[0048] In an alternative embodiment, the long-distance road condition detection method of the present invention may further include the following steps:
[0049] When the retractable sensor structure is in its stowed state, if an abnormal position is detected in a critical component of the retractable sensor structure, a prompt message is generated to notify the user of potential failure risks.
[0050] In this embodiment, when the retractable sensor structure is in its retracted state, a method is provided to detect the status of critical components and generate user alerts. Specifically, when an abnormal position is detected in a critical component of the retractable sensor structure, such as mechanical obstruction or failure to return to its correct position, an alert is automatically generated. This alert can be displayed to the user via an in-vehicle screen or a mobile terminal, ensuring the user is aware of the device's status immediately. The information includes not only the detected type of positional abnormality but also possible cause analysis and suggested solutions. This method enables real-time anomaly detection and self-diagnosis of the retractable sensor structure in its retracted state, allowing for early identification of potential faults and alerts via terminal devices.
[0051] Users can interact with the in-vehicle screen or mobile terminal to generate diagnostic commands. In response to these commands, the status of key components of the retractable sensor structure is checked. This method allows users to proactively monitor the device's status and take timely action when problems are detected.
[0052] In an alternative embodiment, the long-distance road condition detection method of the present invention may further include the following steps:
[0053] When the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, the control will retract the retractable sensor structure into the recess on the top of the vehicle.
[0054] In this embodiment, when the retractable sensor structure has extended from the vehicle roof and is operational, it continuously monitors the environment in front of the vehicle. If an obstacle is detected (e.g., a height restriction bar or a low-altitude obstacle in an environment such as a tunnel or garage), and it is determined that the obstacle may collide with the retractable sensor structure, protective measures are taken. These protective measures include controlling the retractable sensor structure to quickly retract into a recess on the vehicle roof. The purpose of this is to avoid an actual collision between the retractable sensor structure and the obstacle, thereby preventing equipment damage or malfunction.
[0055] In one alternative approach, when the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, the retractable sensor structure is retracted into a recess on the roof of the vehicle. This may specifically include the following steps:
[0056] When the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, a collision avoidance time window is determined based on the current vehicle speed information, and the retractable sensor structure is retracted into the groove on the top of the vehicle within the collision avoidance time window.
[0057] This precise time management and rapid response mechanism ensures that the retractable sensor structure is safely stored before a potential collision occurs, thereby effectively avoiding equipment damage caused by a collision.
[0058] In one alternative approach, if an emergency collision risk is detected while the retractable sensor structure is in the extended / operational state, the control will either retract the retractable sensor structure into a recess on the vehicle roof or de-energize the retractable sensor structure.
[0059] Emergency collision risk refers to the identification of an approach or contact with an external object or event that could cause physical damage or malfunction. These external objects or events include, but are not limited to, birds in flight, falling objects, rapidly approaching obstacles, or other situations that may pose a threat to the normal operation of the equipment.
[0060] Because collisions can damage the internal wiring of the retractable sensor structure or allow foreign objects to enter, causing short circuits or overloads. For example, a bird strike could tear the cable insulation, exposing the bare wires to the metal casing and causing a short circuit. Therefore, protection is provided by quickly cutting off the power supply.
[0061] Reference Figure 4 The diagram shows a flowchart of the long-range road condition detection method provided by this invention. The process begins with receiving a long-range road condition detection command. First, the environment around the vehicle is detected. If the environment is suitable for detection, the process continues to the next step. If it is not suitable for detection, the retractable sensor structure remains in its retracted state. If the environment is suitable for detection, the retractable sensor structure is extended from the top of the vehicle. After the retractable structure extends to the target length, the environmental perception sensor is activated. The environmental perception sensor begins to collect data and transmits the data back to the onboard computer in real time. With the retractable sensor structure extended, the system detects whether there are obstacles in front of the vehicle and whether there is a collision risk between the retractable sensor structure and the obstacle. If there is an obstacle and a collision risk, a retrieval command is generated. Based on this retrieval command, the retractable sensor structure can be retracted into the recess on the top of the vehicle. If there are no obstacles or collision risks, normal operation is possible. Additionally, if the user issues a retrieval command, the retractable sensor structure will also be retracted into the recess on the top of the vehicle.
[0062] In one alternative approach, the environmental sensing sensor is configured to be detachably mounted on top of the telescopic pole structure, allowing the environmental sensing sensor to be replaced with other types of environmental sensing sensors.
[0063] In this embodiment, the environmental perception sensor is mounted on top of the telescopic pole structure using a detachable connection mechanism. This design allows for the use of different types of environmental perception sensors, such as lidar, cameras, ultrasonic sensors, or radar. Through modular design, the vehicle can flexibly replace sensors according to different application requirements.
[0064] Optionally, an attitude sensor can be integrated into the environmental perception sensor to ensure attitude stability under various conditions, thereby improving the accuracy and reliability of data acquisition. Data from all sensors is connected to the onboard computer via a bus for real-time data transmission and processing.
[0065] In one alternative approach, the retractable sensor structure is configured to be housed in a recess in the roof of the vehicle when not in operation, such that the outer surface of the housed structure forms a continuous and smooth transition with the outer surface of the roof of the vehicle.
[0066] In this embodiment, a dedicated recess is designed on the vehicle roof to accommodate the retractable sensor structure. The edges of the recess are designed to seamlessly connect with the outer surface of the vehicle roof to maintain overall aesthetics and aerodynamic performance. The retractable sensor structure extends and retracts via an electric or electromechanical drive system. In the non-operating state, the retractable sensor structure is stored within the recess. The retracted retractable sensor structure forms a continuous, smooth surface with the vehicle roof, reducing air resistance. This design also reduces wind noise and improves passenger comfort.
[0067] In one alternative approach, the retractable rod structure features a streamlined housing design.
[0068] The streamlined shell can reduce the drag coefficient, thereby reducing air resistance when the vehicle is in motion.
[0069] To prevent the retractable pole structure from swaying, tearing, or being damaged by wind during high-speed driving, this invention employs aerodynamic modeling to streamline the pole's shape. This design effectively reduces wind resistance and improves the pole's stability in the wind. Furthermore, the pole's support structure utilizes lightweight, high-strength composite materials, further enhancing the pole's stability and wind resistance when raised. Through these optimizations, the retractable pole structure maintains reliable performance and structural integrity even under high-speed driving conditions.
[0070] The telescopic boom structure consists of multiple telescopic arm sections, connected by inserts or locking mechanisms, providing limiting, buffering, and anti-sway functions. This design not only ensures the stability and safety of the telescopic arm at different lengths but also effectively reduces swaying, improving the overall durability and reliability of the structure.
[0071] The scalable, windproof, and intelligently controlled scalable sensor structure proposed in this invention can achieve more intelligent and efficient long-distance environmental perception and prediction capabilities while ensuring structural safety and aesthetics, thereby improving traffic safety in intelligent driving or manual driving.
[0072] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof. This increased height significantly expands the sensor's field of view, enabling it to detect road conditions ahead earlier and from a greater distance. It also provides a longer reaction time at high speeds. In adverse weather conditions, such as heavy fog or torrential rain, the sensor can extend to a higher position to avoid some low-altitude interference, improving the effectiveness and accuracy of detection. Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.
[0073] Figure 5 A schematic diagram of an embodiment of the long-range road condition detection device of the present invention is shown. A retractable sensor structure is integrated on the vehicle roof. The retractable sensor structure includes a retractable rod structure and an environmental sensing sensor mounted on top of the retractable rod structure, such as... Figure 5 As shown, the device 500 includes a control module 510.
[0074] The control module is used to respond to long-distance road condition detection commands, control the retractable sensor structure to extend from the top of the vehicle, and activate the environmental perception sensor to perform long-distance road condition detection after the retractable rod structure extends to the target length.
[0075] In one alternative approach, the telescopic pole structure comprises a multi-section telescopic arm, and the control module is specifically used for:
[0076] Responding to long-distance road condition detection commands, identify the current long-distance road condition detection scenario;
[0077] Based on the preset mapping relationship between long-distance road condition detection scenarios and telescopic length, determine the telescopic length corresponding to the current detection scenario;
[0078] The determined telescopic length is used as the target length. A telescopic command is generated to control the telescopic sensor structure to extend from the top of the vehicle. The telescopic rod structure is then extended to the target length by adjusting the telescopic arm's extension amount.
[0079] In one alternative approach, the long-range road condition detection command is generated when the vehicle's driving data information meets preset driving conditions and / or the vehicle's surrounding environment information meets preset surrounding environment conditions.
[0080] In one alternative approach, the environmental sensing sensor is configured to be detachably mounted on top of the telescopic pole structure, allowing the environmental sensing sensor to be replaced with other types of environmental sensing sensors.
[0081] In one alternative approach, the retractable sensor structure is configured to be housed in a recess in the roof of the vehicle when not in operation, such that the outer surface of the housed structure forms a continuous and smooth transition with the outer surface of the roof of the vehicle.
[0082] In one alternative embodiment, the long-range road condition detection device of the present invention is further used for:
[0083] When the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, the control will retract the retractable sensor structure into the recess on the top of the vehicle.
[0084] In one alternative approach, the retractable rod structure features a streamlined housing design.
[0085] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof.

Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.
[0086] Figure 6 The diagram shows a structural schematic of an embodiment of the long-distance road condition detection device of the present invention. The specific embodiments of the present invention do not limit the specific implementation of the long-distance road condition detection device.
[0087] like Figure 6 As shown, the long-range road condition detection device may include: a processor 602, a communication interface 604, a memory 606, and a communication bus 608.
[0088] The processor 602, communication interface 604, and memory 606 communicate with each other via communication bus 608. Communication interface 604 is used to communicate with other network elements, such as clients or other servers. Processor 602 executes program 610, specifically performing the relevant steps described in the embodiment of the long-distance road condition detection method.
[0089] Specifically, program 610 may include program code, which includes computer-executable instructions.
[0090] Processor 602 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement embodiments of the present invention. The long-range road condition detection device includes one or more processors, which may be processors of the same type, such as one or more CPUs; or processors of different types, such as one or more CPUs and one or more ASICs.
[0091] Memory 606 is used to store program 610. Memory 606 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk storage device.
[0092] The vehicle roof integrates a retractable sensor structure, which includes a retractable rod structure and an environmental sensing sensor mounted on top of the retractable rod structure. Specifically, program 610 can be called by processor 602 to enable the long-range road condition detection device to perform the following operations:
[0093] In response to a long-distance road condition detection command, the retractable sensor structure is controlled to extend from the top of the vehicle, and after the retractable rod structure extends to the target length, the environmental perception sensor is activated to perform long-distance road condition detection.
[0094] In an alternative embodiment, the telescopic pole structure comprises a multi-section telescopic arm, and program 610 is invoked by processor 602 to cause the long-range road condition detection device to perform the following operations:
[0095] Responding to long-distance road condition detection commands, identify the current long-distance road condition detection scenario;
[0096] Based on the preset mapping relationship between long-distance road condition detection scenarios and telescopic length, determine the telescopic length corresponding to the current detection scenario;
[0097] The determined telescopic length is used as the target length. A telescopic command is generated to control the telescopic sensor structure to extend from the top of the vehicle. The telescopic rod structure is then extended to the target length by adjusting the telescopic arm's extension amount.
[0098] In one alternative approach, the long-range road condition detection command is generated when the vehicle's driving data information meets preset driving conditions and / or the vehicle's surrounding environment information meets preset surrounding environment conditions.
[0099] In one alternative approach, the environmental sensing sensor is configured to be detachably mounted on top of the telescopic pole structure, allowing the environmental sensing sensor to be replaced with other types of environmental sensing sensors.
[0100] In one alternative approach, the retractable sensor structure is configured to be housed in a recess in the roof of the vehicle when not in operation, such that the outer surface of the housed structure forms a continuous and smooth transition with the outer surface of the roof of the vehicle.
[0101] In an alternative manner, program 610 is invoked by processor 602 to cause the long-range road condition detection device to perform the following operations:
[0102] When the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, the control will retract the retractable sensor structure into the recess on the top of the vehicle.
[0103] In one alternative approach, the retractable rod structure features a streamlined housing design.
[0104] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof. This increased height significantly expands the sensor's field of view, enabling it to detect road conditions ahead earlier and from a greater distance. It also provides a longer reaction time at high speeds.

Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.

[0115] The determined telescopic length is used as the target length. A telescopic command is generated to control the telescopic sensor structure to extend from the top of the vehicle. The telescopic rod structure is then extended to the target length by adjusting the telescopic arm's extension amount.
[0116] In one alternative approach, the long-range road condition detection command is generated when the vehicle's driving data information meets preset driving conditions and / or the vehicle's surrounding environment information meets preset surrounding environment conditions.
[0117] In one alternative approach, the environmental sensing sensor is configured to be detachably mounted on top of the telescopic pole structure, allowing the environmental sensing sensor to be replaced with other types of environmental sensing sensors.
[0118] In one alternative approach, the retractable sensor structure is configured to be housed in a recess in the roof of the vehicle when not in operation, such that the outer surface of the housed structure forms a continuous and smooth transition with the outer surface of the roof of the vehicle.
[0119] In one alternative approach, executable instructions cause the long-range road condition detection device / apparatus to perform the following operations:
[0120] When the retractable sensor structure is in the extended state, if an obstacle is detected in front of the vehicle and there is a risk of collision between the obstacle and the retractable sensor structure, the control will retract the retractable sensor structure into the recess on the top of the vehicle.
[0121] In one alternative approach, the retractable rod structure features a streamlined housing design.
[0122] This invention utilizes a retractable rod structure, allowing the environmental perception sensor to extend to a high position on the vehicle's roof. This increased height significantly expands the sensor's field of view, enabling it to detect road conditions ahead earlier and from a greater distance. It also provides a longer reaction time at high speeds. In adverse weather conditions, such as heavy fog or torrential rain, the sensor can extend to a higher position to avoid some low-altitude interference, improving the effectiveness and accuracy of detection. Through these methods, the vehicle's ability to detect road conditions over long distances at high speeds or in adverse weather conditions is significantly enhanced.
