Description

Technical Field

[0001] This utility model relates to the field of vehicle radar technology, and in particular to a vehicle radar controller. Background Technology

[0002] Currently, to meet different detection needs, vehicles are usually equipped with vehicle-mounted ultrasonic radar and vehicle-mounted millimeter-wave radar. Vehicle-mounted ultrasonic radar includes ultrasonic sensors assembled in predetermined positions on the vehicle body and ultrasonic radar controllers used to control the operation of ultrasonic sensors, while vehicle-mounted millimeter-wave radar usually directly adopts millimeter-wave detection controllers that integrate millimeter-wave transmission and control functions.

[0003] However, during implementation, it was found that the two radar controllers had some overlap in hardware functions, which was not fully utilized, increasing hardware costs. Furthermore, when the two radar controllers needed to exchange data, they could only send their own detection data to the vehicle's CAN bus first, and then receive the other's detection data from the CAN bus, making data exchange very cumbersome. In addition, installing two radar controllers in a vehicle would occupy very valuable space resources. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide an on-board radar controller that can realize millimeter wave detection and control ultrasonic sensors to perform ultrasonic detection, thereby reducing hardware costs and improving data interaction efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vehicle-mounted radar controller, comprising:

[0006] The first port of the CAN bus for connecting to an external vehicle;

[0007] A millimeter-wave detection and control module for transmitting millimeter-wave probes, receiving and processing probe return waves reflected from obstacles, and generating millimeter-wave detection data;

[0008] A CAN communication module that is connected to the millimeter-wave detection and control module and the first port, respectively;

[0009] The second port is used for connecting an external ultrasonic sensor;

[0010] An ultrasonic transceiver connected to the second port for bidirectional communication with the ultrasonic sensor;

[0011] An ultrasonic control module connected to the ultrasonic transceiver to drive the ultrasonic transceiver and ultrasonic sensor, and receiving and processing ultrasonic detection signals fed back by the ultrasonic sensor via the ultrasonic transceiver to generate ultrasonic detection data; and

[0012] The data interaction module is connected to the millimeter-wave detection and control module and the ultrasonic control module, respectively, and is used to perform data interaction between the ultrasonic detection data and the millimeter-wave detection data to achieve data aggregation.

[0013] Furthermore, the CAN communication module is also connected to the ultrasonic control module.

[0014] Furthermore, the millimeter-wave detection and control module, the ultrasonic control module, and the data interaction module are integrated into a single SOC processor.

[0015] Furthermore, the vehicle-mounted radar controller also includes:

[0016] The power module is connected to the SOC processor, the CAN communication module, and the ultrasonic transceiver and is externally connected to the vehicle power supply to provide power to the SOC processor, the CAN communication module, and the ultrasonic transceiver.

[0017] Furthermore, the vehicle-mounted radar controller is provided with two second ports.

[0018] Furthermore, the first port and the second port are integrated into a port module.

[0019] After adopting the above technical solution, the present invention has at least the following beneficial effects: The present invention sets up a millimeter-wave detection and control module, a CAN communication module, an ultrasonic transceiver, an ultrasonic control module, and a data interaction module in a vehicle radar controller. The CAN bus is connected to the corresponding first port, and the ultrasonic sensor is connected to the corresponding second port. Thus, only one vehicle radar controller is needed to realize millimeter-wave detection and control the ultrasonic sensor to perform ultrasonic detection. This helps to reduce the space occupied by the controller and reduce hardware costs. Moreover, the data interaction module can quickly realize data interaction between the millimeter-wave detection data generated by the millimeter-wave detection and control module and the ultrasonic detection data generated by the ultrasonic control module within the controller, which helps to improve data interaction efficiency.

It should be understood that the following illustrative embodiments and descriptions are only used to explain the present utility model and are not intended to limit the present utility model. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.

[0022] like Figure 1 As shown, an optional embodiment of this utility model provides a vehicle-mounted radar controller 1, comprising:

[0023] The first port 10 of the CAN bus 5 for connecting to an external vehicle;

[0024] Millimeter wave detection and control module 12 is used to transmit millimeter probe waves, receive and process probe return waves reflected from obstacles, and generate millimeter wave detection data;

[0025] A CAN communication module 13 is connected to the millimeter-wave detection and control module 12 and the first port 10 respectively;

[0026] The second port 14 is used for connecting an external ultrasonic sensor 7;

[0027] An ultrasonic transceiver 15 connected to the second port 14 for bidirectional communication with the ultrasonic sensor 7;

[0028] An ultrasonic control module 16 is connected to the ultrasonic transceiver 15 to drive the ultrasonic transceiver 15 and the ultrasonic sensor 7, and receives and processes the ultrasonic detection signal fed back by the ultrasonic sensor 7 via the ultrasonic transceiver 15 to generate ultrasonic detection data; and

[0029] The data interaction module 17 is connected to the millimeter-wave detection and control module 12 and the ultrasonic control module 16 respectively, and is used to perform data interaction between the ultrasonic detection data and the millimeter-wave detection data to achieve data aggregation.

[0030] This embodiment of the invention incorporates a millimeter-wave detection and control module 12, a CAN communication module 13, an ultrasonic transceiver 15, an ultrasonic control module 16, and a data interaction module 17 within a single vehicle-mounted radar controller 1. A CAN bus 5 is externally connected via a first port 10, and an ultrasonic sensor 7 is externally connected via a second port 14. This allows for millimeter-wave detection and control of the ultrasonic sensor 5 to perform ultrasonic detection with only one vehicle-mounted radar controller 1, reducing the space occupied by the controller and lowering hardware costs. Furthermore, the data interaction module 17 enables rapid data exchange between the millimeter-wave detection data generated by the millimeter-wave detection and control module 12 and the ultrasonic detection data generated by the ultrasonic control module 16 within the controller, improving data exchange efficiency.

[0031] In one optional embodiment of this utility model, such as Figure 1 As shown, the CAN communication module 13 is also connected to the ultrasonic control module 16. In this embodiment, by connecting the CAN communication module 13 to the ultrasonic control module 16, the ultrasonic detection data generated by the ultrasonic control module 16 can be uploaded separately to the CAN bus 5 of the vehicle via the CAN communication module 13.

[0032] In one optional embodiment of this utility model, such as Figure 1 As shown, the millimeter-wave detection and control module 12, the ultrasonic control module 16, and the data interaction module 17 are integrated into a single SOC processor 2. In this embodiment, integrating the above modules into a single SOC processor 2 simplifies the circuit structure and reduces hardware costs. In specific implementations, the data interaction module 17 can be the RAM memory of the SOC processor 2. Typically, both millimeter-wave detection data and ultrasonic detection data are stored in the RAM memory, enabling convenient and rapid interactive processing.

[0033] In one optional embodiment of this utility model, such as Figure 1 As shown, the vehicle-mounted radar controller 1 further includes:

[0034] The power module 18 is connected to the SOC processor 2, the CAN communication module 13, and the ultrasonic transceiver 15, and is externally connected to the vehicle power supply 8. It is used to supply power to the SOC processor 2, the CAN communication module 13, and the ultrasonic transceiver 15. In this embodiment, the power module 18 is also used to supply power to each power-consuming module, ensuring normal and stable operation. In specific implementations, the power module 18 typically boosts or bucks the voltage output from the vehicle power supply 8 to meet the different operating voltage requirements of each power-consuming module.

[0035] In one optional embodiment of this utility model, such as Figure 1 As shown, the vehicle-mounted radar controller 1 has two second ports 14. Since one second port 14 can only connect to a maximum of 6 ultrasonic sensors 7, when there are more than 6 ultrasonic sensors 7 installed on the vehicle body, the number of second ports 14 needs to be increased accordingly. In this embodiment, by setting two second ports 14, a maximum of 12 ultrasonic sensors 7 can be connected, and the number of ultrasonic sensors 7 installed on current vehicles is usually no more than 12, thus effectively meeting the requirements.

[0036] In one optional embodiment of this utility model, such as Figure 1As shown, the first port 10 and the second port 14 are integrated into a port module 9. In this embodiment, integrating the first port 10 and the second port 14 into a port module 9 simplifies the circuit structure and facilitates assembly and external connection operations.

[0037] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present invention.
