[0023] refer to Figure 1 An embodiment of the present application provides a vehicle obstacle avoidance control system, including: a control module 110 and an infrared detector 120 including a cooling component 122, wherein the control module 110 is connected to the infrared detector 120 and the cooling component 122.

[0024] In this embodiment, the infrared detector 120 is used to collect infrared information on the vehicle's driving path. The infrared detector 120 in this embodiment is set on the vehicle equipment. When setting the infrared detector 120, it should be ensured that there are no obstacles in the signal transmission area of ​​the infrared detector 120, so that the infrared detector 120 can effectively collect object information on the vehicle equipment's driving path. The infrared information in this embodiment can be an infrared signal reflected by an object on the vehicle equipment's driving path, or it can be infrared image data.

[0025] Specifically, Figure 1 As shown, the infrared detector 120 includes an infrared focal plane chip 121 and a cooling component 122, wherein the infrared focal plane chip 121 is mainly used to collect and process infrared information, and the cooling component 122 is used to cool the infrared detector 120 in a working state.

[0026] The control module 110 is used to obtain infrared information collected by the infrared detector 120; determine whether there is an obstacle on the vehicle's driving path based on the infrared information; and when it is determined that there is an obstacle on the vehicle's driving path, control the vehicle equipment to avoid the obstacle according to a preset obstacle avoidance strategy.

[0027] In this embodiment, the vehicle equipment can keep the infrared detector 120 in a continuous operation state during operation. The infrared detector 120 emits infrared signals and receives reflection signals from obstacles. The control module 110 receives the obstacle reflection signals collected by the infrared detector 120 and performs pre-processing operations such as filtering and amplification on the obstacle reflection signals to improve the signal quality. Subsequently, a preset obstacle recognition algorithm is used to process the pre-processed infrared signal to determine whether there is an obstacle on the vehicle's driving path and its distance. The preset obstacle recognition algorithm can be one or more of a threshold judgment algorithm and a signal processing algorithm.

[0028] In this embodiment, the infrared detector 120 can be set in front of the vehicle device to obtain obstacle information on the driving path in front of the vehicle device. When it is determined that there is an obstacle on the driving path of the vehicle, the corresponding preset obstacle avoidance strategy can be selected to control the vehicle device to avoid the obstacle. When executing the preset obstacle avoidance strategy, the control module 110 can also dynamically adjust the obstacle avoidance strategy by monitoring the vehicle status and environmental changes in real time.

[0029] like Figure 1 As shown, the vehicle obstacle avoidance control system also includes a communication module 140, wherein the communication module 140 is connected to the control module 110, and the communication module 140 includes a Bluetooth module and a WiFi module. The control module 110 can communicate data with the vehicle terminal 200 through the communication module 140. After the control module 110 obtains the preset obstacle avoidance strategy based on the infrared information, the preset obstacle avoidance strategy can be sent to the vehicle terminal 200 through the communication module 140, so that the vehicle terminal 200 controls the operation of other related modules in the vehicle equipment according to the preset obstacle avoidance strategy to perform obstacle avoidance processing.

[0030] In summary, this embodiment provides a vehicle obstacle avoidance control system, which can equip the vehicle equipment with an infrared detector 120 to realize obstacle recognition, and flexibly set the obstacle avoidance strategy according to the obstacle recognition result, thereby improving the accuracy of obstacle recognition and the flexibility of obstacle avoidance processing during the vehicle obstacle avoidance process. In addition, the infrared detector 120 includes a cooling component 122, which can effectively cool the infrared detector 120 during the operation of the infrared detector 120, thereby avoiding the problem of overheating and damage of the infrared detector 120 due to long working hours, and effectively extending the service life of the infrared detector 120.

[0031] According to a specific implementation of the embodiment of the present application, Figure 1 As shown, the vehicle obstacle avoidance control system further includes: a temperature detection module 130 , which is respectively connected to the control module 110 and the infrared detector 120 , and is used to collect the real-time temperature of the infrared detector 120 .

[0032] The control module 110 obtains the real-time temperature of the infrared detector 120 through the temperature detection module 130, and when the real-time temperature is greater than or equal to a preset temperature threshold, controls the cooling component 122 to start, so as to control the temperature of the infrared detector 120 within a target temperature range.

[0033] In this embodiment, the temperature detection module 130 can adopt a device or detection circuit such as a temperature probe or a temperature sensor that can detect temperature information. The temperature detection module 130 can be set inside or on the surface of the infrared detector 120 according to the requirements of the actual application scenario to facilitate the collection of the real-time temperature of the infrared detector 120.

[0034] In this embodiment, the real-time temperature of the infrared detector 120 collected by the temperature detection module 130 may be the internal temperature or the external surface temperature of the infrared detector 120 , and the specific value and object of the real-time temperature may be determined according to the setting position of the temperature detection module 130 in the actual application scenario.

[0035] In this embodiment, both the preset temperature threshold and the target temperature range can be determined according to the needs of the actual application scenario. It should be noted that in actual application, the preset temperature threshold can be set within the target temperature range, such as a temperature interval of 1°C-3°C less than the highest temperature value of the target temperature range. It can also be set to a range of 1°C-3°C greater than the highest temperature value of the target temperature range. It should be noted that the setting of the preset temperature threshold must ensure that the infrared detector 120 will not be directly damaged due to abnormal high temperature. The setting of the target temperature range must ensure that the infrared detector 120 can operate stably for a long time and accurately collect infrared signals.

[0036] According to a specific implementation of the embodiment of the present application, Figure 2 As shown, the cooling component 122 includes a rotary refrigerator, wherein the rotary refrigerator is arranged on the side of the housing of the infrared detector 120 .

[0037] In this embodiment, the rotary refrigerator can be a rotary Stirling refrigerator, which, based on the Stirling cycle principle, achieves a cooling effect in the alternating cycle of compressed gas and expanded gas through the rotation of the vibrating rotor. The rotary refrigerator is arranged on the side of the housing of the infrared detector 120, and when the control module 110 controls the rotary refrigerator to start, sufficient cooling capacity can be provided for the infrared detector 120 to cool the infrared detector 120 to the target temperature range, thereby ensuring the working state of the infrared detector 120.

[0038] It should be noted that the type of rotary refrigerator can also be adaptively replaced according to the needs of the actual application scenario.

[0039] According to a specific implementation of the embodiment of the present application, Figure 2 As shown, the cooling component 122 also includes a Dewar flask, and the bottom of the Dewar flask is fixedly mounted on the outer shell surface of the infrared detector 120.

[0040] In this embodiment, the Dewar flask, which may also be called Dewar, is electrically connected to the infrared detector 120. The base of the Dewar flask is fixedly mounted on the outer shell surface of the infrared detector 120, which can effectively maintain the vacuum insulation environment required for the low-temperature operation of the refrigerator, ensuring that the detector can work stably in a low-temperature environment.

[0041] In this embodiment, the interior of the Dewar flask can provide a stable low-temperature environment for the detector by storing cryogenic liquids such as liquid nitrogen. It should be noted that the actual structure type of the Dewar flask can be configured according to the needs of the actual application scenario.

[0042] According to a specific implementation of an embodiment of the present application, the infrared detector 120 includes an infrared focal plane chip 121, and the infrared focal plane chip 121 includes an infrared focal plane array and a readout circuit, wherein the infrared focal plane array is made of indium antimonide material, and the infrared focal plane chip 121 is arranged inside a Dewar flask.

[0043] In this embodiment, the infrared focal plane chip 121 of the infrared detector 120 is a semiconductor device that can convert infrared radiation into electrical signals. It is composed of a plurality of infrared detector 120 units, which are arranged on the chip in a two-dimensional array, and each unit can independently receive and respond to infrared radiation.

[0044] The working principle of the infrared focal plane chip 121 is based on the interaction between infrared radiation and semiconductor materials. When infrared radiation hits the chip, it is absorbed by the semiconductor material and excites electrons. These electrons move inside the semiconductor and produce current or voltage changes, which are converted into electrical signals. These electrical signals are then amplified and processed to generate infrared images or data.

[0045] In a specific embodiment, the infrared focal plane array (FPA) in this embodiment can be prepared by indium antimonide material using a p-on-n planar junction process, and has a medium-wave infrared response. The pixels can be arranged in a 640×512 matrix. The readout circuit in this embodiment can use a high-performance detector readout circuit (ROIC) with a specification of 640×512, which can be adapted to various types of infrared detectors 120 such as P-on-N type II superlattice, MCT, indium antimonide, etc. 640×512, 640×480, and 512×512 can be achieved, and the array has an arbitrary windowing function. The detector array signal is read out through four analog taps. The circuit operating temperature range covers 77K~300K, which can meet the high-precision and high-frame rate thermal imaging requirements for military and civilian use.

[0046] In this embodiment, the specific structure of the infrared detector can be as follows: Figure 2As shown, a detector housing 6 is fixedly installed at the bottom of the Dewar flask 3, an indium antimonide focal plane chip is arranged inside the Dewar screen, and the indium antimonide focal plane chip is composed of a focal plane array and a readout circuit interconnected by reverse welding, a detector side shell 5 is fixedly installed on the outer wall of one side of the detector housing 6, and a rotary refrigerator 4 is fixedly installed on the outer wall of the other side of the detector housing 6. A data line 2 is arranged on the top surface of the rotary refrigerator 4, and a detector connector 1 is arranged at one end of the data line 2. Among them, the detector side shell 5 is used to provide assistance and support for the infrared detector to be installed at a designated position on the vehicle equipment.

[0047] It should be noted that the specific structure of the infrared detector 120 in this embodiment and the actual operation mode of the infrared focal plane chip 121 can be configured according to the needs of the actual application scenario. The infrared detector 120 structure provided in this embodiment has the advantages of small size, light weight, low input power and low cost, which can be more conducive to use in the automotive field.

[0048] In actual application, the infrared focal plane chip 121 is set inside the Dewar flask, which can ensure the low-temperature environment required for the infrared focal plane chip 121 to work, greatly improves the working stability and application breadth of the infrared detector 120, and can realize the installation of the infrared detector 120 in vehicle equipment to realize obstacle avoidance control and other solutions.

[0049] According to a specific implementation of the embodiment of the present application, the control module 110 is used to obtain the interval distance information between the vehicle equipment and the obstacle; Determine a preset obstacle avoidance strategy according to a comparison between the interval distance information and a preset distance threshold, wherein the preset obstacle avoidance strategy includes at least two or more obstacle avoidance strategies; According to the obstacle avoidance strategy corresponding to the interval distance information, the vehicle equipment is controlled to avoid obstacles.

[0050] In this embodiment, the control module 110 can obtain the distance information between the obstacle and the vehicle equipment by analyzing the infrared signal collected by the infrared detector 120. In a feasible embodiment, the vehicle equipment can also be provided with a distance sensor, and when it is determined that there is an obstacle on the path of the vehicle equipment, the distance information between the vehicle equipment and the obstacle is collected through the distance sensor.

[0051] After determining the interval distance information, different obstacle avoidance strategies can be adaptively selected. For example, if the interval distance information is greater than the first distance threshold, the first obstacle avoidance strategy can be selected, wherein the first obstacle avoidance strategy can be to replan the driving route to bypass the obstacle to achieve obstacle avoidance. If the interval distance information is less than or equal to the second distance threshold, the second obstacle avoidance strategy can be selected, wherein the second distance threshold is less than the first distance threshold, and the second obstacle avoidance strategy can be to stay in place and wait for the obstacle to be cleared before continuing to move forward along the original driving route.

[0052] It should be noted that the settings of the preset distance threshold and the preset obstacle avoidance strategy can be customized according to the needs of the actual application scenario, and examples are not given here one by one.

[0053] According to a specific implementation of the embodiment of the present application, the control module 110 is used to collect obstacle avoidance strategy execution data of the vehicle equipment, wherein the obstacle avoidance strategy execution data includes obstacle avoidance success rate and response time; Execute data acquisition optimization and adjustment strategy according to obstacle avoidance strategy; When the infrared detector 120 runs continuously for a preset time, the working parameters of the infrared detector 120 and the preset obstacle avoidance strategy are optimized according to the optimization adjustment strategy, wherein the working parameters include the detection sensitivity.

[0054] In this embodiment, the control module 110 collects the obstacle avoidance strategy execution data of the vehicle during each obstacle avoidance process, that is, the obstacle avoidance process execution result. The obstacle avoidance strategy execution data includes data such as the single obstacle avoidance strategy execution result, the success rate of multiple obstacle avoidance strategy executions, and the total response time of a single obstacle avoidance strategy execution process.

[0055] After collecting the obstacle avoidance strategy execution data, the control module 110 may store the obstacle avoidance strategy execution data in a local storage unit. When the storage unit includes obstacle avoidance strategy execution data for a period of time, or includes obstacle avoidance strategy execution data corresponding to at least two obstacle avoidance steps, the control module 110 may generate a corresponding optimization adjustment strategy based on the obstacle avoidance strategy execution data.

[0056] In this embodiment, the adjustable working parameters of the infrared detector 120 include sensitivity, response speed, resolution, noise, etc.

[0057] For example, if the response time in the obstacle avoidance strategy execution data is long, the corresponding optimization adjustment strategy may be to increase the detection sensitivity of the infrared detector 120 so that the infrared detector 120 can complete the obstacle recognition response more quickly. The corresponding optimization strategy may also be to adjust the preset obstacle avoidance strategy corresponding to the interval distance information, from re-planning the route to waiting for the obstacle to be cleared, etc. It should be noted that the actual content of the optimization adjustment strategy needs to be configured according to the needs of the actual application scenario, and is not specifically limited here.

[0058] In this embodiment, after the infrared detector 120 has been running continuously for a certain period of time, the control module 110 can automatically start the vehicle obstacle avoidance system optimization measures to comprehensively collect information from the infrared detector 120 and automatically detect various modules of the vehicle equipment to ensure the accuracy of the vehicle obstacle avoidance control and the stability of the system operation.

[0059] In summary, this embodiment provides a vehicle obstacle avoidance control method, by synchronously setting a rotary refrigerator outside the infrared detector, the rotary refrigerator can effectively cool the detector when it is in normal use, so as to avoid the detector from being continuously high temperature when working for a long time, and ensure the use effect of the detector.

At the same time, the detector can perform regular system optimization, so as to continuously ensure the detection accuracy and use effect of the detector. And by flexibly adjusting the preset obstacle avoidance strategy, the vehicle equipment can complete the obstacle avoidance process more efficiently and quickly during the obstacle avoidance process.
