Fig. 1 is a schematic configuration diagram of a radar apparatus 100 according to an embodiment of the present utility model. As shown in fig. 1, in a specific embodiment, the radar apparatus 100 includes a plurality of radars 10, a processor 12, and a controller 13, where each radar 10 includes a transceiver module 11, the transceiver modules 11 corresponding to at least two radars 10 in the plurality of radars 10 are hard-wired to the processor 12, so that the at least two radars 10 share the processor 12, and the controller 13 is hard-wired to the processor 12. The transceiver module 11 is a millimeter wave transceiver module, and the processor 12 mainly processes the point cloud data.

This embodiment has at least two radars 10 arranged to share one processor 12 and a controller 13, and processing target data by the same processor 12 CAN increase the speed of processing the target data, and has at least two radars 10 arranged to be connected by hard wire, and has the controller 13 arranged to be connected to the processor 12 by hard wire, CAN increase the data transmission speed compared to CAN wire.

In this embodiment, any one radar 10 of the at least two radars 10 has a processor 12 and a controller 13. It is understood that one radar 10 of the at least two radars 10 has a processor 12 and a controller 13, the processor 12 and the controller 13 being integrated within the same radar 10. This embodiment corresponds to the arrangement of at least one radar 10 having a processor 12 and a controller 13, and the arrangement of the other radar 10 having no processor 12 and no controller 13 for processing target data, and the arrangement of the other radar 10 having only the transceiver module 11, corresponding to the function of only the sensor. The other radars 10 all transfer the acquired point cloud data to the radar 10 having a processor 12 and a controller 13.

Fig. 2 is a schematic installation view of the radar 10 and the mounting bracket 20 according to one embodiment of the present utility model. As shown in fig. 2, in this embodiment, the radar apparatus 100 further includes at least two mounting brackets 20 arranged in one-to-one correspondence with at least two radars 10, each mounting bracket 20 having a clamping portion 21, the clamping portion 21 being provided rotatably and connected with the corresponding radar 10 to adjust the angle of the corresponding radar 10, thereby changing the detection range of the corresponding radar 10 and improving the convenience of adjusting the detection range of the radar 10. In the conventional technical scheme, once the radar 10 is mounted on the vehicle, the detection range is fixed, so that the radar 10 detection angle can be adjusted by adjusting the mounting bracket 20 after the radar 10 is mounted on the vehicle by arranging the mounting bracket 20.

In this embodiment, the number of the at least two mounting brackets 20 is two, the two mounting brackets 20 are adjacently arranged, and the angle between the engaging portions 21 of the two mounting brackets 20 is adjustable. It will be appreciated that this embodiment may reduce the number of connection harnesses between two radars 10 by arranging the mounting brackets 20 adjacent to each other, saving costs.

In a preferred embodiment, two mounting brackets 20 may be integrated together, thereby improving the ease of installation of the radar 10. Here, the two mounting brackets 20 and the two radars 10 can be regarded as one multi-functional radar 10, which corresponds to integration into one multi-functional radar 10.

In this embodiment, each of the mounting brackets 20 includes a rotation shaft 22 connected to the catching portion 21, and the rotation shafts 22 of the two mounting brackets 20 are arranged in parallel. Referring to fig. 2, two rotating shafts 22 are adjacently arranged, and the clamping portions 21 connected with the two rotating shafts 22 are arranged in a staggered manner, wherein one clamping portion 21 is located above the rotating shaft 22, and the other clamping portion 21 is located below the rotating shaft 22, so that the two clamping portions 21 can be ensured to normally rotate. It can be understood that the rotating shaft 22 drives the corresponding clamping portion 21 to rotate when rotating, so as to drive the radar 10 to rotate, so as to adjust the detection range of the radar 10. Here, the rotation angle range of the locking portion 21 is 0 ° to 80 °, and in other embodiments, the rotation angle range of the locking portion 21 may be set according to specific design requirements. In this embodiment, one of the two snap-in portions 21 is left and one is right, so that the two radars 10 are positioned one to the left of the rotation shaft 22 and one to the right of the rotation shaft 22 when mounted.

In a preferred embodiment, two clamping portions 21 are provided detachably with corresponding shafts 22. When only one radar 10 is needed, one of the clamping parts 21 may be removed, that is, one of the radars 10 may be removed, and it should be noted that the removed radar 10 does not have the processor 12 and the controller 13, only has the sensor function, and the radar 10 having the processor 12 and the controller 13 is still to remain, so that the acquired point cloud data can be ensured to be processed.

In this embodiment, the two radars 10 may be front radars and side radars on the vehicle, and in the prior art, since the front left angle radar, the front right angle radar and the front radars all perform the point cloud data acquisition and processing separately, none of the common processor 12 and the controller 13 perform the analysis processing on the target, and the target is transmitted by the CAN network after being processed, which causes a great delay. In addition, the vehicle longitudinal function requires the use of three radars 10 and corresponding three processors 12, three controllers 13 in front of the vehicle, which increases the difficulty of executing the function processing and unnecessary cost waste to some extent. This embodiment corresponds to an improvement over the front radar and the lateral radar on existing vehicles, which are mounted on the mounting bracket 20 and are configured to be detachable. The processor 12 and the controller 13 are integrated in the front radar, and when the lateral radar is detached, the front radar can still be used as an original front radar, so that intelligent driving functions of vehicles such as ACC, AEB and FCTA are realized. In this embodiment, the two radars 10 and the two mounting brackets 20 can be regarded as a whole, and if the multifunctional radar is used, the front radar is not required to be mounted in the middle of the front bumper of the vehicle, and only the multifunctional radar is required to be mounted at the left front corner and the right front corner of the vehicle, so that the functions of the front two corner radars and the front radar can be realized. The multifunctional radar has higher processing speed on point cloud data of the original independent lateral radar and forward radar, does not have information output delay phenomenon, and can accurately control intelligent driving functions such as ACC, AEB, FCTA and the like of the vehicle. The embodiment changes the front radar and the lateral radar into the general combined multifunctional radar, so that the variety of the radar can be reduced to a certain extent, and the number of processors can be reduced.

In this embodiment, the radar 10 having the processor 12 and the controller 13 is provided with a harness connector 40, and other radars 10 can communicate data with the radar 10 by hard-wired connection to the harness connector 40.

In this embodiment, the radar apparatus 100 further includes two motors 30, which are respectively located at two ends of the rotating shaft 22 and are connected to the two rotating shafts 22 in a one-to-one correspondence manner, so as to respectively drive the corresponding rotating shafts 22 to rotate, thereby adjusting the angle between the two clamping portions 21. In this embodiment, the motor 30 drives the rotating shaft 22 to rotate, so as to drive the clamping part 21 to rotate. In other embodiments, other driving devices may be used to rotate the shaft 22. Here, two motors 30 are provided at both ends of the two rotating shafts 22, one motor 30 drives only one of the rotating shafts 22 to rotate, and the other rotating shaft 22 is pivotally connected with a part on the motor 30, so that the convenience of installation of the multifunctional radar 10 can be improved by the design. When the multifunctional radar 10 is mounted on a vehicle, only two motors 30 need to be fixedly mounted.

In this embodiment, the radar apparatus 100 further includes two sensors arranged in one-to-one correspondence with the two motors 30 for acquiring the operation parameters of the corresponding motors 30. Here, the control unit on the vehicle is connected to both the two motors 30 and the two sensors for determining the angle between the two clamping portions 21 according to the operation parameters of the two motors 30, thereby determining the detection range of the two radars 10.

This embodiment also provides a vehicle including the radar apparatus 100 described above. The radar apparatus 100 is not described in detail herein.

In this embodiment, when the radar apparatus 100 is turned on, each radar 10 starts to transmit and receive point cloud data, and transmits the acquired point cloud data to a processor 12 connected with the radar 10, so that all the point cloud data are processed by the radar 10 having the processor 12, targets in the point cloud data are screened and processed by a controller 13 of the radar 10, the processing speed of the point cloud data is improved, and finally, intelligent driving functions such as ACC, AEB and FCTA of the vehicle are executed by two actuators such as an body stability control system (ESP) and a power control system (EMS) of the vehicle. In addition, the transceiver module 11 of the radar 10 is connected to the processor 12 by a hard wire, and the data transmission speed CAN be increased relative to the CAN wire.
