Description

Technical Field

[0001] The present disclosure relates to the technology of a radar device installed in a vehicle, and particularly to an installation method for a radar device equipped with an adjustment mechanism corresponding to a radar module.

Background Art

[0002] Chinese Patent Application Publication No. 1441513 discloses a radar device capable of aligning the axis of an antenna with the axis of a vehicle even when the surface of the antenna is covered with a cover or the like. In the assembly process of the radar device composed of a cover installed in the above-described casing, the relative positional relationship between the antenna axis of the antenna assembled in the casing and a part of the casing or the platform is detected. When the radar device is installed in a vehicle, the antenna axis can be adjusted to be parallel to the vehicle axis by using data regarding the relative positional relationship between the housing or a part of the platform and the antenna axis.

[0003] Radar systems mounted on the front of a vehicle must be adjusted and installed considering their height and position. Due to the diversity of vehicle models, the mounting position on the front or rear of the vehicle may be limited. For example, other components such as trailer hooks, license plates, or other equipment may be mounted on the front or rear of the vehicle. Because the possible mounting positions on the front or rear of each vehicle differ, the mounting position may be high or low. When mounted low, radar systems are susceptible to interference from the ground. When mounted high, radar systems may not be able to detect objects close to the ground, potentially resulting in unnecessary warnings or false alarms. Furthermore, when radar is mounted on the front of a vehicle, the radar module within the radar system must be fixed and protected, and the radar signals transmitted and / or received by the radar module must not be interfered with by related components. Therefore, techniques are needed to adjust the detection area of ​​the radar system after installation and to protect the radar module within the radar system without interfering with the radar signal. [Overview of the project]

[0004] This disclosure relates to radar equipment technology with adjustment mechanisms that can adjust the angle of a radar beam generated by a radar module as required, and adjust and set the detection area of ​​the radar module based on relevant information such as the position of the vehicle on which it is installed. This disclosure also relates to radar equipment technology with adjustment mechanisms that correspond to and protect an internal radar module, and adjustment mechanisms that do not interfere with a radar module that transmits and / or receives radar signals.

The radar device includes a radar module configured to generate a radar detection area. The radar device also includes an adjustment mechanism. The adjustment mechanism includes a vehicle mounting portion configured to be mounted on a first side of a vehicle. The adjustment mechanism also includes a radar mounting portion pivotably connected to the vehicle mounting portion. The radar mounting portion can pivot relative to the vehicle mounting portion and is configured to secure the radar module.

[0006] A second aspect of this disclosure provides a method for installing a vehicle radar device on the ground. The installation method includes the step of providing a radar device configured to generate a radar detection area. The installation method also includes the step of mounting the radar device to a first side of a vehicle. The radar device includes a first side facing the direction of a radar beam and a second surface facing the first side of the vehicle, with an angle of inclination between the first surface and the second surface. The installation method also includes the step of obtaining a first width of the first side, a horizontal distance between the vertical centerline of the radar device and the first side, and a vertical distance between the center point of the radar device and the ground. The installation method also includes the step of adjusting and fixing the angle of inclination between the first surface and the second surface of the radar device according to the vertical distance. The installation method also includes the step of setting a warning area within the radar detection area according to the first width, horizontal distance, vertical distance, and angle of inclination. The warning area includes a first width that is greater than or equal to the first width.

[0010] Similar reference numbers and symbols within different drawings indicate similar elements. It should also be understood that the various exemplary embodiments shown in the drawings are for illustrative purposes only and are not necessarily drawn to scale.

[0011] According to one or more embodiments of the present disclosure, Figure 1A is an illustrative stereoscopic view of a typical radar device 100, Figure 1B is an illustrative rear view of a typical radar device 100, and Figures 1C and 1D are illustrative views of two sides (a first side 132 and a second side 135) of a typical radar device 100. Referring to Figures 1A and 1B, the radar device 100 includes a radar module 110 configured to generate a radar beam and an adjustment mechanism 120 for mounting the radar module 110. The case 115 of the radar module 110 includes a connector 111. The connector 111 is configured to surround a signal connector 117 within the radar module 110. The signal connector 117 is also an internal circuitry metal connector of the radar module, such as a metal pin, connection pin, or pin connector, and may be configured to connect to an external electronic control unit (such as the electronic control unit 160 in Figures 2A-2C) for setting up the radar module 110 or for processing the detection signal (or reflected signal) of the radar beam from a target. For a description of the signal connector 117, please refer to Figures 1G-1I and the relevant paragraphs below.

[0012] Details of the radar module 110 are described below with reference to Figures 1G to 1J. Figures 1G to 1I illustrate a front view, exploded view, and front perspective view of a radar device 100 according to one or more embodiments of the present disclosure, respectively, and Figure 1J is a functional block diagram illustrating the internal components of the radar module 110 according to one or more embodiments of the present disclosure. The adjustment mechanism 120 includes a radar mounting section 130 and a vehicle mounting section 140. The radar device 1100 may include a first surface 131 and a second surface 141 opposite the first surface 131. The first surface 131 is located on the radar mounting section 130 and faces the direction of the generated radar beam (as may be referenced in Figures 2B and 2C and related paragraphs). The second surface 141 is located on the vehicle mounting section 140 and faces the vehicle. The vehicle mounting section 140 can be used to secure the radar device 100 to a vehicle, for example, by locking the second surface 141 of the vehicle mounting section 140 to the front or rear side of the vehicle (for example, the first side 210 of the vehicle 200 in Figures 2A-3D). In other words, the second surface 141 of the vehicle mounting section 140 faces either the front or rear side of the vehicle (for example, the first side 210 of the vehicle 200 in Figures 2A-3D). As shown in Figures 1A-1D, the radar mounting section 130 can be used to secure the radar module 110, for example, by locking the radar module 110 to the radar mounting section 130 via a plurality of fasteners 112. The radar mounting section 130 has an opening 137 as an antenna window, which allows the antenna area corresponding to the antenna of the radar module 110 (see Figures 1I and 1J) to be exposed to the first surface 131 through the opening 137, and the radar beam generated by the antenna in the radar module 110 to travel through the opening 137 in the direction that the first surface 131 is facing. The radar mounting section 130 also includes a connector protection section 138 that covers the connection section 111 of the radar module 110 and protects the connection section 111 and the signal connector 117 inside it on the first surface 131, thereby preventing the connection section 111 and the signal connector 117 inside it from being damaged by an object coming from the first surface 131 (in the direction of the vehicle forward).The radar mounting section 130 may be pivotably connected to the vehicle mounting section 140 via a pivot shaft PA. In some embodiments, the radar mounting section 13 may be fixed by fasteners (such as fasteners 133a and 136a in Figures 1E and 1F) to openings 132a in the first side surface 132 and 135a in the second side surface 135, through which the pivot shaft PA passes, thereby allowing the radar mounting section 130 to pivot relative to the vehicle mounting section 140 with respect to the pivot shaft PA. Therefore, the radar mounting section 130 can be adjusted to pivot relative to the vehicle mounting section 140 with respect to the rotation axis PA, thereby allowing the first surface 131 of the radar mounting section 130 to be parallel to the second surface 141 of the vehicle mounting section 140, or allowing the first surface 131 of the radar mounting section 130 to be oriented at an inclination angle (such as the inclination angle 121 in Figures 1E and 1F) with respect to the second surface 141 of the vehicle mounting section 140. The elevation angle of the radar device and the method for setting it will be described in detail below with reference to Figures 1E and 1F.

[0013] Figures 1E and 1F illustrate the angle adjustment settings on the side of a typical radar device 100 according to one or more embodiments of the present disclosure. The radar mounting portion 130 can be locked by fasteners 133a and 136a to the opening 132a of the first side surface 132 and the opening 135a of the second side surface 135, respectively, so that the radar mounting portion 130 can pivot relative to the vehicle mounting portion 140 with respect to the rotation axis PA. The first surface 131 of the radar mounting portion 130 is oriented to form an inclination angle 121 with respect to the second surface 141 of the vehicle mounting portion 140. Since the radar mounting portion 130 can pivot relative to the vehicle mounting portion 140, the inclination angle 121 can be set to 0 degrees, that is, the first surface 131 of the radar mounting portion 130 will be parallel to the second surface 141 of the vehicle mounting portion 140 (as shown in the center of Figures 1E and 1F), or the inclination angle 121 can be adjusted between plus 7 degrees and minus 7 degrees, that is, the first surface 131 of the radar mounting portion 130 will be non-parallel to the second surface 141 of the vehicle mounting portion 140 (as shown on the left and right sides of Figures 1E and 1F).

[0014] As shown in FIG. 1C, the first side surface 132 of the radar mounting portion 130 has an opening 132a (through which the aforementioned rotation axis PA passes) and an opening 132b, where the shape of the opening 132b is different from the shape of the opening 132a. In this example, the size of the opening 132a is the same as the size of the corresponding opening (not shown) of the vehicle mounting portion 140. Therefore, as shown in FIG. 1E, the opening 132a can be locked to the corresponding opening (not shown) of the vehicle mounting portion 140 via the fastener 133a. Also, in this example, as shown in FIG. 1E, the size of the opening 132b is larger than the size of the corresponding opening (not shown) of the vehicle mounting portion 140. That is, when the radar mounting portion 130 is set to be oriented with an inclination angle 121 at a specific angle (between plus 7 degrees and minus 7 degrees) with respect to the vehicle mounting portion 140, the fastener 133b can pass through the larger-sized opening 132b and lock to the corresponding opening (not shown) of the vehicle mounting portion, whereby, as shown in the left figure (a) and the right figure (c) of FIG. 1E, the first surface 131 of the radar mounting portion 130 and the second surface 141 of the vehicle mounting portion 140 are fixed at the set inclination angle 121.

[0015] As shown in Figure 1D, the second side surface 135 of the radar mounting portion 130 has an opening 135a (through which the aforementioned rotation axis PA passes) and an opening 135b. In this example, the shape of opening 135a is the same as the shape of opening 135b, and the sizes of openings 135a and 135b are the same as the size of the corresponding opening (not shown) of the vehicle mounting portion. Therefore, as shown in Figure 1F, when the radar mounting portion 130 is adjusted to pivot with respect to the vehicle mounting portion 140 at an inclination angle 121 (the inclination angle is not equal to 0), only opening 135a can be locked to the corresponding opening (not shown) of the vehicle mounting portion 140 via the fastener 136a, as shown in left (a) and right (c) of Figure 1F, and opening 135a cannot be locked to the corresponding opening (not shown) of the vehicle mounting portion because it is misaligned with the corresponding opening (not shown). As shown in Figure (c) in the center of Figure 1F, once the radar mounting portion 130 is adjusted to pivot relative to the vehicle mounting portion 140 without an inclination angle (the inclination angle is equal to 0, and the first surface 131 is parallel to the second surface 141), the openings 135a and 135b can be locked into the corresponding openings (not shown) of the vehicle mounting portion 140 by fasteners 136a and 136b, respectively, thereby fixing the first surface 131 of the radar mounting portion 130 parallel to the second surface 141 of the vehicle mounting portion 140.

[0016] Referring to Figures 1G-1J, the radar module 110 includes a case 115 and internal components enclosed within the case 115. The internal components enclosed within the case 115 include an antenna 113, a controller 116, and a signal connector 117. The antenna 113 is configured to transmit or receive a radar beam (or radar signal). The controller 116 is connected to the antenna 113 and the signal connector 117 to control the antenna 113 to transmit or receive a radar beam (or radar signal) and form a radar detection area. The signal connector 117 can output radar reflected signals generated within the radar detection area and received and processed by the controller 116 according to the control of the controller 116, or can receive external signals / commands that can be received via the signal connector 117, enabling the controller 116 to configure and operate the radar module 110. The case 115 includes an antenna area 114 corresponding to the antenna 113 and a connection area 111 surrounding the signal connector 117. The connector portion 111 surrounding the signal connector 117 can be adapted to the shape of various external connectors connected to the radar module 110, ensuring a secure connection between the signal connector 117 and the external connector. The antenna area 114 of the housing 115 should be understood as the area on which the antenna 113 transmits or receives radar signals on the first surface 131. That is, for the radar module 110 (or antenna 113) to function properly, the antenna area 114 must not be obstructed by any object. As discussed above, the radar mounting portion 130 includes an opening 137 as an antenna window. This antenna window corresponds to the antenna area 114 of the antenna 113 within the radar module 110. Therefore, the opening 137 in the radar mounting section 130, which serves as an antenna window corresponding to the antenna region 114 of the antenna 113 within the radar module 110, allows the antenna 113 to transmit and / or receive a radar beam from the corresponding antenna region 114 of the antenna 113 through the opening 137 (antenna window), thereby generating a radar detection area.Hereinafter, the installation and setting of the radar device 100 on the vehicle 200 will be described with reference to FIGS. 2A to 3E.

[0017] FIGS. 2A to 2C are diagrams illustrating a typical radar device 100 installed on a vehicle 200 according to one or more embodiments of the present disclosure. Referring to FIGS. 2A to 2C, the radar device 100 can be installed on the first side surface 210 of the vehicle 200 via the vehicle installation portion 140 of the radar device 100 described above. In one embodiment, the first side surface 210 can be the front side of the vehicle 200. In another embodiment, the first side surface 210 can be the rear side of the vehicle 200. As shown in FIGS. 2B and 2C, the radar device 100 can emit a plurality of radar beams, namely radar beams 105a, 105b, and 105c, which form a radar detection area 105, in various directions. In one embodiment, the radar beams 105a, 105b, and 105c are respectively transmitted by a plurality of transmitting antennas (TX) to form the radar detection area 105. The radar detection area 105 covers a range of ±90 degrees perpendicular to the normal line L of the second surface 141 of the radar device 100, exceeding the left and right sides of the vehicle, that is, exceeding the left and right sides of the first side surface 210. When a moving object appears within the radar detection area 105 and is within the driver's blind spot, the moving object can be detected by the radar beams 105a to 105c. The radar device 100 can be connected to an electronic control unit (ECU) 160. In some embodiments, the ECU 160 can set a warning area according to the radar detection area 105 composed of the radar beams 105a, 105b, and 105c, and provide a warning or target-related information only when a target object is detected within the warning area. In some embodiments, when the radar beams 105a, 105b, and 105c detect a target object, the ECU 160 can classify the target object while detecting and warning the target object according to preset conditions, such as analyzing the energy and position of the radar reflected beam to distinguish whether the target object is a vehicle, a person, or another object.

[0018] Since the radar device 100 is installed at various positions on the first side 210 of the vehicle 200, the detection range of the radar beam is affected. Therefore, after the radar device 100 is installed on the first side of the vehicle 200, it needs to be calibrated or configured, such as setting the detection range or warning area of ​​the radar device 100 in the ECU 160. Typical settings for a radar device installed in a vehicle are described in detail below with reference to Figures 3A to 3E.

[0019] Figures 3A to 3E illustrate typical configurations of a radar device 100 installed in a vehicle 200 according to one or more embodiments of the present disclosure. First, since the width of the warning area of ​​the radar device 100 (as shown in Figure 3D) is related to the width W of the first side 210 shown in Figure 3A (as shown in Figure 3D), the value of the width W of the first side 210 of the vehicle 200 needs to be input into the ECU 160 connected to the radar device 100.

[0020] Since the warning area of ​​the radar device 100 must cover the entire area in front of the first side 210, the installation position of the radar device 100 on the first side 210 of the vehicle 200 must be determined. As shown in Figure 3B, the value of the horizontal distance HD between the centerline RCL of the radar device 100 and the centerline VCL of the first side 210 of the vehicle 200 is input into the ECU 160 connected to the radar device 100. Then, as shown in Figure 3C, the vertical distance VD between the center point of the radar device 100 and the ground G, i.e., the installation height of the radar device 100, is input into the ECU 160 connected to the radar device 100.

[0021] As discussed above, when the radar device 100 is installed on the first side 210 of the vehicle 200, the tilt angle 121 (as shown in Figures 1A to 1F) between the first surface 131 (as shown in Figures 1A to 1F) and the second surface 141 (as shown in Figures 1A to 1F) of the radar device 100 can be adjusted, so that the area covered by the radar detection area 105 of the radar beams 105a to 105c emitted by the radar device 100 can be adjusted in sync with the difference in the tilt angle 121, that is, the tilt angle 121 can be changed according to the different areas to be covered. The tilt angle 121 can be determined according to the vertical distance VD (installation height of the radar device 100) between the center point of the radar device 100 and the ground G. In one embodiment, the vertical distance VD is in the range of 40 cm to 140 cm, and the corresponding adjustment range of the tilt angle 121 is between plus 7 degrees and minus 7 degrees. In one embodiment, the larger the vertical distance VD, the smaller the inclination angle 121 becomes. For example, when the vertical distance VD is 40 cm, the inclination angle 121 can be adjusted to plus 7 degrees; when the vertical distance VD is between 70 cm and 110 cm, the inclination angle can be adjusted to 0; or when the vertical distance VD is between 110 cm and 140 cm, the inclination angle can be adjusted to minus 7 degrees.

[0022] As discussed above, after determining the width W of the first side 210 of the vehicle 200, the horizontal distance HD between the centerline RCL of the radar device 100 and the centerline VCL of the first side 210 of the vehicle 200, the vertical distance VD between the center point of the radar device 100 and the ground G, and the inclination angle 121 between the first surface and the second surface of the radar device 100, the ECU 160 of the radar device 100 (as shown in Figures 2A-2C) can determine a warning area within the radar detection area 105 of the radar device 100 based on this information, where the width of the warning area is greater than the width W of the first side 210 of the vehicle 200, such as warning area 170a and warning area 170b shown in Figure 3D.

[0023] Figure 3D shows that, according to various embodiments, the ECU sets up different warning areas, warning area 170a or warning area 170b, within the detection area of ​​the radar beam, where warning area 170a is set up according to the UK PSS standard and warning area 170b is set up according to the EU standard (UN R159). According to the UK PSS, the width W1 of warning area 170a is the width W of the first side 210 plus 1 meter, and the length L1 of warning area 170a is 2 meters. According to the EU standard (UN R159), the width W2 of warning area 170b is the width W of the first side 210 plus 1 meter, and the length L2 is 3.7 meters. If a target object is located in warning area 170a or warning area 170b, the radar system issues a warning, and the ECU notifies the vehicle user, for example, via sound or light.

[0024] In some embodiments, the defined warning area can be tested using target objects. As shown in Figure 3E, target objects 300 can be positioned sequentially at the center and on both sides of the warning area 170c for calibration testing to adjust the mounting position of the radar device on the first side 210 of the vehicle 200, or to adjust the aforementioned tilt angle 121 (as shown in Figures 1E and 1F). Similarly, as shown in Figure 3E, target objects can be positioned, for example, at the lower or upper height limit (not shown) of the warning area 170d to adjust the aforementioned tilt angle 121.

[0025] Figure 4 is a flowchart illustrating a typical installation process for a radar device according to one or more embodiments of the present disclosure. In step S410, a radar device (such as radar device 100 in Figures 1A-1F) is provided that can emit a radar beam (such as radar beams 105a, 105b, and 105c in Figures 2B-2C). In step S420, the radar device is installed by a user, for example, on a first side of a vehicle (such as the first side 210 of vehicle 200 in Figures 2A-3D). In some embodiments, the first side of the vehicle is the front or rear side of the vehicle, and the radar device includes a first surface facing the direction of the radar beam and a second surface facing the front or rear side of the vehicle, with an inclination angle between the first and second surfaces (such as inclination angle 121 in Figures 1E and 1F). In step S430, the first width of the first side (e.g., the width W of the first side 210 of the vehicle 200 in Figure 3A), the horizontal distance between the radar device and the vertical centerline of the first side (e.g., the horizontal distance HD between the centerline RCL of the radar device 100 and the centerline VCL of the first side 210 of the vehicle 200 in Figure 3B), and the vertical distance between the center point of the radar device and the ground (e.g., the vertical distance VD between the center point of the radar device 100 and the ground G in Figure 3C) are obtained, for example, by user input. In step S440, the inclination angle between the first surface and the second surface of the radar device (e.g., the inclination angle 121 in Figures 1E and 1F) is adjusted and fixed by the ECU, for example, according to the vertical distance. In step S450, the warning area of ​​the radar beam of the radar device is set according to the first width, horizontal distance, vertical distance, and inclination angle. The warning area includes, for example, a second width greater than or equal to the first width, as set by the ECU.

[0026] In certain configurations, the installation process further includes providing an ECU (such as ECU160 in Figures 2A-2C) connected to the radar equipment.

[0027] In certain configurations, the installation process further includes the step of defining warning areas (such as warning areas 170a and 170b in Figure 3D, and warning areas 170c and 170d in Figure 3E) within the radar detection area.

[0028] In certain configurations, the installation process further includes adjusting the installation position or tilt angle of the radar device on the first side of the vehicle by sequentially positioning target objects in the center and left and right sides of the warning area for calibration testing, as shown in Figure 3E.

[0029] In certain configurations, the installation process further includes the step of positioning the target object at the upper and lower limits of the detection height of the warning area in order to adjust the tilt angle, as shown in Figure 3E.

[0030] In certain configurations, the vertical distance is between 40cm and 140cm, and the tilt angle is between +7 degrees and -7 degrees.

[0031] The technology provided in this disclosure allows for the adjustment of a radar system using an adjustment mechanism, thereby simultaneously adjusting the detection area of ​​the radar module, enabling the radar module to detect and locate targets within the detection area formed by beamforming. Furthermore, by setting the radar's installation position, height, and angle, the detection area of ​​the radar module can be adjusted, and a warning area can be set within the detection area to warn or notify targets within the warning area, further enabling target classification. In addition, the technology provided in this disclosure also includes, in addition to the functions described above, an opening serving as an antenna window and a connector protection section for protecting the radar module's connections (and signal connectors). This effectively protects the radar module from the front of the vehicle and prevents interference with the antenna area corresponding to the antenna within the radar module during radar signal transmission and / or reception by exposing the antenna area of ​​the radar module through the opening serving as an antenna window.
