Description

Technical Field

[0001] The present application relates to the field of autonomous driving technology, and in particular to a radar simulation device and vehicle, which can be applied to business scenarios such as ports, border crossings, road freight, urban distribution, mines, and airports. Background Art

[0002] The working principle of radar is to transmit electromagnetic waves. When the electromagnetic waves encounter a target during the propagation path, they cannot completely penetrate, so part of the electromagnetic waves will be reflected from the target surface. The radar then uses the design of the internal hardware circuit to receive the reflected signal and compare the characteristics with the transmitted signal to extract various parameters of the target. The target parameters that generally need to be known are mainly the distance to the target, the azimuth of the target, and the movement speed of the target.

[0003] In actual radar products, to verify the actual performance of the radar, an ideal flat and wide outdoor test site is usually found. During the test, parameters such as target distance, target angle, and target speed are calibrated. After the radar detects the target, manual measurement is performed to determine whether the actual value is consistent with the radar measurement value.

[0004] However, the above test method has a relatively complicated test process, high test cost, large test error and low test accuracy; at the same time, it cannot effectively implement the test of long-distance and wide-angle radar. Utility Model Content

[0042] In actual radar products, to verify the radar's true performance, an ideal, flat, and wide outdoor test site is typically found. During testing, parameters such as target distance, target angle, and target speed are calibrated. After the radar detects the target, manual measurements are performed to determine whether the actual values ​​match the radar measurements. It should be noted that the purpose of radar testing is to ensure the accuracy and reliability of the radar system and to optimize radar performance to meet the needs of specific applications.

[0043] The testing method of the related technology has a relatively complicated testing process and requires a large testing cost. It is very difficult to find a testing site that meets the requirements, and there are large testing errors in manual measurement. Outdoor testing sites will inevitably have other external interferences. Therefore, the actual testing accuracy of the above-mentioned testing method is not high. Moreover, due to cost considerations, the above-mentioned testing method is usually suitable for short-range radar testing and cannot be used to test long-range and wide-angle radars. The test is relatively limited and cannot ensure that different models of radars can be tested. The long-term reliability of the radar cannot be well guaranteed.

[0044] In response to the above technical problems, the embodiments of the present application provide a radar simulation device and a vehicle, including a radar simulator. In this way, the radar simulator can simulate the transmission and reception processes of the radar to be tested. Based on the observation and analysis of the simulation results, the performance of the radar to be tested can be evaluated, and improvements and optimizations can be made, thereby simplifying the test process, reducing the test cost, and maximizing the test accuracy. At the same time, the present application can be applied to the testing of radars at different distances, with a wider scope of application, ensuring the long-term reliability of the radar to be tested. In addition, the present application includes a controller and a host, which helps to improve the degree of automation of the simulation process, reduce the workload of manual operation, and enhance the user experience.

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0046] An embodiment of the present application provides a vehicle, which includes at least a vehicle body and a radar simulation device.

[0047] For example, the vehicle may be an intelligent self-driving vehicle, or an ordinary human-driven vehicle, such as a car, a truck, a trailer, or a flatbed truck, etc. This is not limited in this embodiment.

[0048] In the embodiment of the present application, the radar simulation device can be installed on the vehicle body. There is no further limitation on the setting of the radar simulation device, and it can be set according to actual needs.

[0049] In the embodiments of this application, the connection method between the radar simulator and the vehicle body is not limited. For example, the radar simulator and the vehicle body can be connected via a connector. For example, the connector can be a bolt, stud, screw, or rivet. This embodiment does not limit this.

[0050] It should be noted that the radar simulation device in this embodiment includes but is not limited to being installed on a vehicle.

[0051] For example, a radar simulator can be installed on a ship. By simulating different environments and conditions such as ship positioning, avoidance operations, radar images, intersecting ships, wind currents, waves, rain and snow interference, etc., the radar simulator can provide a training platform close to the real operating environment, allowing operators to learn and improve their radar operating skills in a simulated environment.

[0052] For example, when a radar simulator is installed on a vehicle, it can help improve driving safety and enhance driving convenience. For example, the radar simulator can also be used for radar operation training in aircraft and other fields, thereby providing a safe and economical training method and helping to avoid the dangers and cost issues that may be encountered in actual operation. This embodiment is not limited to this.

[0053] In the embodiments of this application, a radar simulator is used to simulate a radar under test. It should be noted that a radar simulator is a device used to simulate the operating principles of a radar. It can simulate the transmission and reception of radar signals through software without the need for actual radar equipment. By observing and analyzing the simulation results, the performance of the radar system can be evaluated and improved and optimized.

[0054] The specific structure of the radar to be tested is not limited. For example, the radar simulation device in this embodiment can be used to test the performance of a 77-79 GHz millimeter wave radar. This embodiment does not limit this.

[0055] The structure of the radar simulation device provided in this application is described in detail below.

[0056] Reference Figures 1 to 17 As shown, the radar simulation device may include a main cabinet 110 and a control cabinet 120, wherein the control cabinet 120 is installed with a controller and a host 130, and the main cabinet 110 is installed with a radar simulator 140, and the controller, host 130 and radar simulator 140 are electrically connected to each other.

[0057] In the embodiment of the present application, there is no limitation on the material of the main cabinet 110 and the control cabinet 120. For example, the main cabinet 110 can be provided with a first sheet metal structure, and the control cabinet 120 can be provided with a second sheet metal structure. The first sheet metal structure and the second sheet metal structure can be made of SPCC high-quality cold-rolled steel and electrostatically sprayed. In this way, not only can the main cabinet 110 and the control cabinet 120 be guaranteed to have a high structural strength, but the wear resistance of the main cabinet 110 and the control cabinet 120 can also be improved, the service life of the main cabinet 110 and the control cabinet 120 can be extended, and the long-term reliability of the main cabinet 110 and the control cabinet 120 can be further improved.

[0058] SPCC high-quality cold-rolled is a cold-rolled carbon steel sheet, which is made by further cold-rolling ordinary carbon hot-rolled steel strip into a steel plate with a thickness of less than 4mm. Its surface quality and appearance dimensional accuracy are significantly better than hot-rolled coils. This material is not only high in strength, but also not easy to warp or crack under pressure, and has a high-quality surface finish.

[0059] Electrostatic spraying is a commonly used coating technology. Its principle is based on the effects of electrostatic adsorption and charge repulsion. The principle of electrostatic spraying enables the spraying material to be more evenly distributed on the surface of the sprayed object, providing the advantages of high efficiency, saving spraying materials and reducing waste generated during the spraying process.

[0060] In the embodiment of the present application, the electrical connection method between the controller, host 130, and radar simulator 140 is not limited. For example, the controller, host 130, and radar simulator 140 may be electrically connected to each other via a wired method, such as a wire, or they may be electrically connected to each other wirelessly. This embodiment is not limited to this.

[0061] In the embodiment of the present application, the radar simulator 140 has terminals that are used to point toward the target object during operation. This improves the alignment between the radar simulator 140 and the target object, maximizing the ability of the radar simulator 140 to transmit and receive signals from the target object, thereby improving detection accuracy.

[0062] It should be noted that "orientation" can be understood as the face-to-face placement of the terminals of the radar simulator 140 and the target object. Furthermore, there is no limitation on the target object; for example, target objects generally include aerial targets, ground targets, surface targets, and electromagnetic targets. This embodiment does not impose any limitation on this.

[0063] In this embodiment, radar simulator 140 is configured to input parameters of the radar under test. These parameters may include, but are not limited to, radar transmit power, antenna gain, system loss, number of array elements, wavelength, and mechanical scan angle. Furthermore, waveform parameters such as pulse repetition frequency, sampling frequency, pulse width, and range resolution unit also need to be considered. The settings of these parameters directly impact the accuracy and reliability of the simulation results. Therefore, when using radar simulator 140 for simulation testing, it is crucial to ensure that these parameters are correctly set.

[0064] In this way, when simulating the radar to be tested, the radar simulator 140 needs to input a series of parameters of the radar to be tested to ensure the accuracy and effectiveness of the simulation, which helps to improve the accuracy of the simulation results, and is beneficial to evaluate the performance of the radar to be tested through observation and analysis of the simulation results, and to make improvements and optimizations.

[0065] In this embodiment, the radar simulator 140 is further configured to simulate the signal transmission and reception of the radar to be tested to the target object. The working principle of the radar simulator 140 is as follows:

[0066] Radar simulator 140 may include a transmitter and a receiver; the terminals are the transmitter's transmitting end and the receiver's receiving end, respectively. The transmitter transmits a signal, such as an electromagnetic wave signal. The transmitter's transmitted signal may be pulsed or continuous wave, which is not limited in this embodiment. The transmitted signal may encounter a target object and be reflected by it, forming a reflected signal.

[0067] The receiver includes an antenna, a front-end receiver and a signal processor. The front-end receiver is electrically connected to the antenna and the signal processor respectively. The antenna is used to receive the reflected signal reflected back by the target object, convert it into an electrical signal, and send the electrical signal to the front-end receiver. The front-end receiver is responsible for amplifying the received electrical signal and sending it to the signal processor. The signal processor is configured to process the received electrical signal.

[0068] During the signal processing phase, the signal processor filters, amplifies, and removes noise from the received signal to extract information about the target object. The processed signal can include information such as the target's position, speed, and distance. This information can be used to evaluate the radar's performance, such as its detection range, resolution, and anti-interference performance.

[0069] In this embodiment, the controller is configured to control the working state of the radar simulator 140, and the host 130 is configured to perform parameter processing.

[0070] The controller controlling the working state of the radar simulator 140 may include: controlling the start or stop of the radar simulator 140, which is not limited in this embodiment; or, the controller may also control the working state of other electrical components.

[0071] The host 130 performs parameter processing. For example, the host 130 can be used for data input, collection, processing, feedback, output, etc., which is not limited in this embodiment.

[0072] Therefore, the radar simulation device provided in this embodiment can evaluate the performance of the radar to be tested based on the observation and analysis of the simulation results, and make improvements and optimizations, simplify the test process, reduce the test cost, and maximize the test accuracy; at the same time, the present application can be applied to the testing of radars of different distances, with a wider scope of application, ensuring the long-term reliability of the radar to be tested; in addition, the present application includes a controller and a host 130, which helps to improve the degree of automation of the simulation process, reduce the workload of manual operation, and improve the user experience.

[0073] In one possible implementation, referring to Figure 3 As shown, the number of radar simulators 140 may include multiple radar simulators 140, and the multiple radar simulators 140 are installed at intervals in the main cabinet 110. The multiple radar simulators 140 each have a terminal, and the terminals of the multiple radar simulators 140 are used to face the target object during operation.

[0074] In this embodiment, there is no limitation on the number of radar simulators 140. For example, the number of radar simulators 140 can be two, three, or more. In this embodiment, five radar simulators 140 are mainly used as an example for description.

[0075] In this way, multiple radars under test can be simulated at the same time; or, different target models, signal propagation conditions and interference factors can be simulated. The performance of different radars under test can be evaluated based on the observation and analysis of the simulation results, so that different radars under test can detect and track multiple targets at the same time, thereby improving the multi-target processing capability.

[0076] In one possible implementation, referring to Figure 3 As shown, a plurality of mounting platforms 150 may be provided in the main cabinet 110 , and the plurality of mounting platforms 150 may be arranged along the circumference of the main cabinet 110 .

[0077] Among them, there is no limit on the number of mounting platforms 150, which can be set according to actual needs; in addition, there is no limit on the connection method between the mounting platform 150 and the main cabinet 110. For example, the mounting platform 150 and the main cabinet 110 can be integrally formed, which helps to improve the installation strength of the mounting platform 150 and the main cabinet 110, thereby ensuring the installation strength of the radar simulator 140.

[0078] In this embodiment of the present application, multiple radar simulators 140 can be installed on the same mounting platform 150, with the terminals of the multiple radar simulators 140 located on the same side or different sides. This helps save installation space, optimizes the layout, facilitates wiring, and helps reduce the risk of wire crosstalk.

[0079] Alternatively, in an embodiment of the present application, the number of mounting platforms 150 may be the same as the number of radar simulators 140, and multiple radar simulators 140 may be installed one-to-one on multiple mounting platforms 150, and multiple radar simulators 140 may be staggered along the height direction of the main cabinet 110.

[0080] Exemplarily, the main cabinet 110 can be a square structure, a part of the radar simulators 140 can be installed at the top of the main cabinet 110 along the height direction, and a part of the radar simulators 140 can be installed at the bottom of the main cabinet 110 along the height direction, and the radar simulators 140 located at the top and the radar simulators 140 located at the bottom can be staggered.

[0081] In this way, on the one hand, direct interference between radar simulators 140 can be avoided, signal overlap and conflict can be reduced, thereby improving the stability of the radar simulation device and further improving the reliability of the simulation; on the other hand, the staggered arrangement can more effectively utilize spatial resources, ensure that each radar simulation device can obtain a better working environment, avoid mutual interference, and thus optimize the allocation and utilization efficiency; on the other hand, the staggered arrangement of multiple radar simulators 140 can cover a wide area and reduce detection blind spots. The coverage of each radar simulator 140 can complement each other, so that the entire system can monitor the target object more comprehensively, thereby improving detection accuracy.

[0082] In one possible implementation, referring to Figure 1 and Figure 6 As shown, a test radar placement window 160 may be opened on the main cabinet 110 , and the radar simulator 140 is used to face the target object through the test radar placement window 160 and transmit and receive signals to the target object.

[0083] The purpose of test radar placement window 160 is to optimize the performance of radar simulator 140 and ensure its detection accuracy. The design and selection of test radar placement window 160 are crucial to improving the performance of the radar under test. First, the choice of test radar placement window 160 directly affects the detection range and accuracy of radar simulator 140. For example, test radar placement window 160 can be divided into different categories based on wavelength, which determines the detection range and resolution of radar simulator 140.

[0084] In addition, the test radar placement window 160 can also reduce external interference and improve signal quality. By designing the test radar placement window 160, external interference, such as electromagnetic interference or interference from other wireless signals, can be reduced, thereby improving the signal-to-noise ratio of the signal and ensuring the stability and reliability of the radar simulator 140.

[0085] In one possible implementation, referring to Figure 11 As shown, a display 170 may be installed in the control cabinet 120 and electrically connected to the controller and host computer 130. Thus, the display 170 can display parameters of the radar simulator 140; alternatively, the display 170 may also display required software operation indicators, etc. This embodiment is not limited to this, and specific configurations may be made based on actual needs.

[0086] In the present application, refer to Figure 10 and Figure 11As shown, the control cabinet 120 may include a placement table 121, on which a wireless mouse 122 and a wireless keyboard 123 may be mounted. The wireless mouse 122 and the wireless keyboard 123 are both electrically connected to the host 130. In this way, using the wireless mouse 122 and the wireless keyboard 123 can avoid the constraints of dragging wires, thereby improving the user experience.

[0087] In one possible implementation, referring to Figures 10 to 15 As shown, the radar simulator may further include an alarm 180. Alarm 180 may be located on the main cabinet 110 or on the control cabinet 120. This embodiment is not limited thereto. Alarm 180 is electrically connected to the controller and is configured to issue an alarm signal when the parameters of the radar simulator 140 fail to meet standards.

[0088] For example, the alarm 180 may be a warning light; or, the alarm 180 may be a visual alarm, an audible alarm, a tactile alarm, or an olfactory alarm. The configuration of the alarm 180 may ensure that the alarm signal has sufficient intensity to attract the operator's attention, or has a distinct and specific shape.

[0089] In a feasible implementation, a wave absorbing member may be attached to the interior of the first sheet metal structure, and a wave absorbing member may be attached to the interior of the second sheet metal structure.

[0090] The absorbing member is made of an absorbing material, such as graphite, conductive particles, graphene, silicon carbide, etc. Furthermore, the shape of the absorbing material includes, but is not limited to, a single-layer flat plate, a double-layer flat plate, or a multi-layer flat plate. This embodiment does not limit this.

[0091] In this way, during the detection process of the radar simulator 140, the use of absorbing materials can create an environment with almost no reflected signals, providing an environment with almost no interference for the testing of the radar simulator 140, thereby maximizing the simulation accuracy of the radar simulator 140.

[0092] In one possible implementation, referring to Figures 10 to 15 As shown, the bottom of the main cabinet 110 may be provided with a travel wheel 190, and a locking mechanism may be provided on the travel wheel 190. In addition, the bottom of the control cabinet 120 may be provided with a travel wheel 190, and a locking mechanism may be provided on the travel wheel 190. This is not limited in this embodiment.

[0093] Exemplarily, the traveling wheel 190 may be a roller, a steering wheel, a driving wheel, a driven wheel, etc.; the locking mechanism may be a mechanical lock or an electronic lock, which is not limited in this embodiment and may be specifically configured according to actual conditions.

[0094] In this way, by setting the traveling wheels 190, it is convenient to push the movement of the main cabinet 110 and the control cabinet 120. In addition, by setting the locking mechanism, the stability and stability of the main cabinet 110 and the control cabinet 120 in complex environments can be improved, and the risk of slipping can be avoided, thereby ensuring the working stability of the radar simulator 140 to the greatest extent and ensuring the simulation accuracy of the radar simulator 140.

[0095] In one possible implementation, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 8 As shown, the main cabinet 110 can be provided with a side door 111 and a tail door 112. In this way, opening the side door 111 helps to facilitate the assembly and debugging of the internal structure of the main cabinet 110, and opening the tail door 112 helps to assemble and debug the radar simulator 140 inside the main cabinet 110, thereby helping to avoid mutual interference problems and improve the efficiency of assembly and debugging.

[0096] Reference Figure 10 and Figure 11 As shown, the control cabinet 120 can be provided with a display cabinet door 124 and a host cabinet door 125. Opening the display cabinet door 124 helps to install and repair the display 170, and opening the host cabinet door 125 helps to facilitate the installation and repair of the host 130, helps to avoid mutual interference problems, and improves the efficiency of assembly and debugging.

[0097] In this embodiment, an acrylic cover can be installed on the display cabinet door 124. This allows the content of the display 170 to be clearly visible from the outside without opening the display cabinet door 124, thereby improving the user experience. This design utilizes the transparency of acrylic material, making the display 170 not only decorative but also serving as a window for displaying screen content.

[0098] Therefore, an embodiment of the present application provides a radar simulation device and a vehicle, including a radar simulator. In this way, the radar simulator can simulate the transmission and reception process of the radar to be tested. Based on the observation and analysis of the simulation results, the performance of the radar to be tested can be evaluated, and improvements and optimizations can be made, thereby simplifying the test process, reducing the test cost, and maximizing the test accuracy. At the same time, the present application can be applied to the testing of radars at different distances, with a wider scope of application, ensuring the long-term reliability of the radar to be tested.
