Description

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.
[0003] With the rapid development of intelligent vehicle driving, the use of on-board sensors to interact with the outside world to perceive the surrounding environment has become a common function of current vehicle driving. This function can provide more useful information for driving, facilitate vehicle driving and improve driving safety. At present, during driving, laser radar is mostly used to detect the real-time distance between the front vehicle and the front vehicle, and timely alarm is issued when the safe distance is exceeded. However, there is currently no solution for detecting abnormal conditions such as road collapse. Existing vehicles cannot effectively detect and identify abnormal conditions of the road ahead, which will cause the vehicle to fall and other situations, and cannot effectively ensure driving safety.
[0004] To this end, in the prior art, a laser radar can be installed to detect the road condition ahead. However, a single detection method may result in detection errors, and its detection and recognition effect is poor. In addition, a camera or other visual sensor can be installed on the front side of the vehicle to detect the road condition in real time during driving. However, the visual recognition algorithm is complex and costly, and its recognition effect is poor in poor lighting conditions (such as driving at night). Summary of the invention
[0005] To address the deficiencies of the above-mentioned prior art, the present invention provides a vehicle road integrity detection and warning system, method and vehicle. A group of infrared imagers and laser radars are arranged on the vehicle, and logical control and information processing are performed on the infrared imagers and laser radars according to the actual driving process. The infrared imagers and laser radars are controlled to perform imaging scanning of the road surface in the traveling direction in a cruising state or a continuous state. According to the two types of scanning results, a road surface integrity status image is drawn and an abnormal road surface warning ahead is issued, thereby effectively improving the detection accuracy and driving safety.

[0054] Embodiment 1
[0055] This embodiment provides a vehicle road integrity detection and warning system, such as Figure 1 and Figure 2 As shown, the system includes a laser radar 1, a laser radar cruise bracket 2, a laser radar cruise control motor, an infrared imager, an infrared imaging cruise bracket, an infrared imaging cruise control motor 8, a rain sensor, a light sensor and a logic controller.
[0056] Among them, a laser radar is set to perform a road integrity scanning operation on the road where the vehicle is traveling. The laser radar is installed on a laser radar cruise bracket 2, and then installed on the top of the vehicle through the laser radar cruise bracket 2. The laser radar cruise bracket 2 has a built-in laser radar cruise control motor 9. The laser radar cruise control motor 9 is electrically connected to the logic controller and can be driven according to the control instructions issued by the logic controller. The laser radar cruise control motor 9 can then be driven to rotate the laser radar cruise bracket 2 and drive the laser radar to perform multi-angle ground scanning operations, so that the laser radar executes the corresponding operating state.
[0057] Similarly, an infrared imager is provided for scanning the road surface integrity of the vehicle's traveling road. In the present embodiment, two infrared imagers are provided, namely, a left infrared imager 3 and a right infrared imager 6. Each infrared imager is mounted on a corresponding infrared imaging cruise bracket (i.e., a left infrared imaging cruise bracket 4 and a right infrared imaging cruise bracket 7), and is respectively mounted above the left and right headlights in front of the vehicle through the infrared imaging cruise bracket. The infrared imaging cruise brackets are equipped with infrared imaging cruise control motors 8, which are electrically connected to the logic controller and can be driven according to control instructions issued by the logic controller. The infrared imaging cruise control motor 8 can then be driven to rotate the infrared imaging cruise bracket and drive the infrared imager to perform multi-angle ground scanning operations, so that the infrared imager executes the corresponding operating state.
[0058] In addition, the embodiment also provides a rain sensor and a light sensor 5 on the outside of the vehicle. Figure 3 As shown, the rain sensor is used to detect the rainfall information in real time, and the light sensor is used to detect the light intensity information in real time; a logic controller is set in the vehicle, and the logic controller is electrically connected to the rain sensor and the light sensor 5, and is used to generate control instructions for the operating status of the laser radar and the infrared imager on the vehicle according to the detected rainfall information and light intensity information, combined with the preset control logic.
[0059] Issued.
[0060] In this embodiment, the operating states of the laser radar and the infrared imager are set, and the operating states include a cruising state and a continuous state, which are respectively:
[0061] (1) The cruising state is: when the horizontal angle is the reference 0° state, the cruising bracket is driven to rotate by controlling the motor, thereby driving the laser radar and the infrared imager to perform reciprocating cruising ground scanning operations according to the scanning angle from the horizontal downward 10° and then back to the horizontal 0° position, and the reciprocating cruising ground scanning operation is performed every set time (set to every 1 second in this embodiment);
[0062] Specifically, in the cruise state, the laser radar cruise control motor built into the laser radar cruise bracket starts the cruise state according to the cruise state control instruction, driving the laser radar to move downward 10° from the reference 0° and then return to the 0° reference position, performing a reciprocating cruise ground scanning operation once per second; similarly, the infrared imaging cruise control motors built into the left infrared imaging cruise bracket and the right infrared imaging cruise bracket start the cruise state according to the cruise state control instruction, driving the left infrared imager and the right infrared imager respectively to move downward 10° from the reference 0° and then return to the 0° reference position, performing a reciprocating cruise ground scanning operation once per second.
[0063] (2) The continuous state is: when the horizontal angle is 0° as the reference, the motor is controlled to drive the cruise bracket to rotate, thereby driving the laser radar and infrared imager to perform continuous ground scanning operations according to the fixed scanning angles corresponding to the current situation.
[0064] In this embodiment, in order to ensure the effective implementation of the continuous state, different scenarios are pre-set, namely: according to the amount of rainfall, the rainfall information is divided into light rain, moderate rain, heavy rain and rainstorm, moderate rainfall and below include light rain and moderate rain, and moderate rainfall and above include heavy rain and rainstorm; according to the size of the light intensity, the light intensity information is divided into high, medium and low, high light intensity is during the day, medium light intensity is during the sunrise and sunset period and at night with auxiliary lighting, low light intensity is at night, among which medium and low light intensities are collectively referred to as night.
[0065] Furthermore, in the continuous state, when the horizontal angle is a reference 0° state, the range of the fixed scanning angle is 5 to 10° horizontally downward.
[0066] Specifically, when the detected rainfall information is moderate or below, and when the detected light intensity information is medium, the fixed scanning angle is 5° horizontally downward. At this time, the laser radar cruise control motor built into the laser radar cruise bracket starts the continuous state according to the continuous state control instruction, and controls the laser radar to continuously scan the ground at a fixed angle of 5° downward from the reference 0°, and the infrared imaging cruise control motors built into the left infrared imaging cruise bracket and the right infrared imaging cruise bracket start the continuous state according to the continuous state control instruction, and control the left infrared imager and the right infrared imager to perform continuous ground scanning at a fixed angle position of 5° downward from the reference 0°.
[0067] Similarly, when the detected rainfall information is moderate or above, and when the detected light intensity information is low, the fixed scanning angle is 10° horizontally downward. At this time, the laser radar cruise control motor built into the laser radar cruise bracket starts the continuous state according to the continuous state control instruction, and controls the laser radar to continuously scan the ground at a fixed angle of 10° downward from the reference 0°, and the infrared imaging cruise control motors built into the left infrared imaging cruise bracket and the right infrared imaging cruise bracket start the continuous state according to the continuous state control instruction, and control the left infrared imager and the right infrared imager to perform continuous ground scanning at a fixed angle position of 10° downward from the reference 0°.
[0068] Based on the above settings, in this embodiment, the control logic of the logic controller is:
[0069] (1) When the vehicle is moving, when rainfall information is detected, the rain sensor starts to transmit a working signal to the logic controller, and the logic controller sends a control instruction to the laser radar and infrared imager and its cruise control motor according to the preset conditions. After receiving the control instruction sent by the logic controller, the laser radar is started to operate in a continuous state to continuously scan the road surface, and the infrared imager is started to enter a continuous state to continuously scan the road surface;
[0070] (2) When no rainfall information is detected during the vehicle's movement, the rain sensor turns off the working signal and transmits it to the logic controller. The logic controller sends a control command to the laser radar and infrared imager and their cruise control motor according to preset conditions. After receiving the control command sent by the logic controller, the laser radar is started to operate in a cruise state to perform a cruise scanning operation on the road surface, and the infrared imager is started to operate in a cruise state to perform a cruise scanning operation on the road surface;
[0071] (3) When the vehicle is moving, when the light intensity information is detected to be high, that is, when it is detected to be daytime, the light sensor turns off the continuous working signal transmission to the logic controller, and the logic controller sends a control instruction to the laser radar and infrared imager and its cruise control motor according to the preset conditions. After receiving the control instruction sent by the logic controller, the laser radar is started to operate in the cruise state to perform a cruise scanning operation on the road surface, and the infrared imager is started to enter the cruise state to perform a cruise scanning operation on the road surface;
[0072] (4) When the vehicle is moving and the light intensity information is detected to be medium or low, that is, when it is detected to be at night, the light sensor starts to transmit the continuous working signal to the logic controller. The logic controller sends control instructions to the laser radar and infrared imager and its cruise control motor according to the preset conditions. After receiving the control instructions sent by the logic controller, the laser radar is started to operate in a continuous state to continuously scan the road surface, and the infrared imager is started to operate in a continuous state to continuously scan the road surface.
[0073] In addition, when facing various complex situations, the control logic of the logic controller is:
[0074] When rainfall information is detected and night conditions are triggered, the lidar and infrared imager are started to operate continuously;
[0075] When rainfall information is detected and daytime conditions are triggered, the lidar and infrared imager are started to operate continuously;
[0076] When no rainfall information is detected and the daytime condition is triggered, the lidar and infrared imager are started to enter the cruise state;
[0077] When no rainfall information is detected and night conditions are triggered, the lidar and infrared imager are started to operate in a continuous state.
[0078] Through the design of the above control logic, the laser radar and infrared imager scan in different states under different conditions. In normal weather, the original laser radar maintains its ability to identify the road ahead and the vehicle ahead. In rainless and daytime conditions, its field of view is relatively moderate, so the cruise ground scanning mode is enabled to intermittently scan and identify the ground ahead to reduce vehicle risks caused by changes in road conditions. At the same time, it can also take into account the scanning and identification of the front of the vehicle to avoid the risks brought by the vehicle ahead. In rainy, foggy and nighttime conditions, its field of view and environmental factors have a greater impact at this time, so the continuous ground scanning mode is enabled. By continuously scanning and identifying the ground ahead, when the vehicle is driving slowly in extreme weather, when faced with the identification of the vehicle ahead and the identification of ground changes, it can give priority to continuously identifying ground changes with a greater impact, thereby ensuring driving safety.
[0079] Furthermore, the system proposed in this embodiment also includes a processor and an alarm device arranged inside the vehicle, wherein the processor is used to generate a road integrity status image based on the road scanning information received in real time from the laser radar and infrared imager, and to identify abnormal road surfaces and their areas based on the generated image, and to generate alarm information based on the identification result; the alarm device is used to receive the alarm information and issue image, icon, and voice alarms. Through this setting, after identifying the abnormal road surface, the driver and passengers can be reminded through images, icons, voice reminders, etc., to achieve the purpose of avoiding danger.

[0083] According to the rainfall information and the light intensity information, combined with the preset control logic, a control instruction for the operating state of the laser radar and the infrared imager on the vehicle is generated; the operating state includes a cruising state and a continuous state;
[0084] According to the operation state control instruction, the laser radar and the infrared imager are respectively controlled to start and execute the corresponding operation state to perform the road surface scanning operation of the vehicle traveling road;
[0085] Based on real-time road scanning information, road anomaly detection and abnormality alarm are performed.
[0086] Furthermore, the above-mentioned cruising state is: when the horizontal angle is the reference 0° state, the cruising bracket is driven to rotate by controlling the motor, thereby driving the laser radar and the infrared imager to perform reciprocating cruising ground scanning operations according to the scanning angle from the horizontal downward 10° and then back to the horizontal 0° position, and the reciprocating cruising ground scanning operations are performed once every set time;
[0087] The above-mentioned continuous state is: when the horizontal angle is the reference 0° state, the cruise bracket is driven to rotate by controlling the motor, thereby driving the laser radar and infrared imager to perform continuous ground scanning operations according to the fixed scanning angles corresponding to the current situation.
