Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an RVC camera module and a dynamic vehicle auxiliary line system. Background Technology

[0002] With the popularization and technological development of intelligent vehicles, most intelligent vehicles on the market now have reversing camera systems to assist drivers in parking smoothly. Existing reversing camera systems mainly include an in-vehicle camera, a 360-degree panoramic imaging system / domain controller, and an in-vehicle display system. Among these, current technology primarily relies on the 360-degree panoramic imaging system / domain controller to generate dynamic lane lines in the generated image. A problem with this approach is the high cost of the 360-degree panoramic imaging system / domain controller. Therefore, developing a novel in-vehicle device with dynamic lane line functionality to reduce the equipment cost of existing solutions is a direction that requires further research by those skilled in the art.

[0029] Example 1, please refer to Figure 1-2 :

[0030] A dynamic vehicle lane system includes: an in-vehicle display system 200 and an in-vehicle camera 100.

[0031] In this example, four vehicle-mounted cameras 100 are configured and installed in the front, rear, left, and right directions of the vehicle body. Each vehicle-mounted camera 100 is signal-connected to the vehicle-mounted display system 200, and each vehicle-mounted camera 100 includes an RVC camera module.

[0032] The RVC camera module includes: lens 110, sensor 120, image signal processor ISP 130, serializer Serdes 140, POC circuit module 150, connector 160, and power management chip PMIC 170.

[0033] The lens 110 is connected to the sensor 120 via a signal connection. The lens 110 is used to collect ambient light signals and output the ambient light signals to the sensor 120.

[0034] The sensor 120 is connected to the graphics signal processor ISP 130. The sensor 120 is used to convert the ambient light signal into an electrical signal and output the electrical signal to the graphics signal processor ISP 130.

[0035] The graphics signal processor (ISP) is connected to the serializer Serdes140 via a signal connection. The ISP is configured to receive the steering communication signal output by the serializer Serdes140, integrate the electrical signal with the communication signal to generate a video signal containing dynamic auxiliary lines, and send the video signal to the serializer Serdes140.

[0036] The serializer Serdes 140 is connected to the POC circuit module 150 and the connector 160 respectively. The serializer Serdes 140 acts as a relay converter, used to output steering communication signals to the graphics signal processor ISP via the IIC interface, and to convert the video signal into a high-speed serial signal and output it to the connector 160 via the MIPI interface. The connector 160 is used to output the high-speed serial signal to the vehicle display system 200.

[0037] The POC circuit is connected to the power management PMIC signal and is used to separate the video signal and the high-speed serial signal. The power management PMIC is connected to the sensor 120, the graphics signal processor ISP 130, and the serializer Serdes 140, respectively, and is used to supply power to the sensor 120, the graphics signal processor ISP 130, and the serializer Serdes 140.

[0038] In this example, the graphics signal processor ISP130 is implemented using an external FH8330 mounted on the sensor 120 (the FH8330 is a mature product; commercially available FH8330s are all equipped with the function of receiving steering communication signals and integrating the electrical signals with the communication signals to generate a video signal containing dynamic vehicle auxiliary lines). Meanwhile, the sensor 120 uses a MIA1301, the power management chip PMIC170 uses an MPQ7928, and the serializer Serdes140 uses a MAX96705.

[0039] Example 2, please refer to Figure 3-4 :

[0040] The difference between Example 2 and Example 1 is that, in this example:

[0041] The sensor 120 uses an S5K4ACXB, and the graphics signal processor (ISP) is integrated within the sensor 120; the power management chip PMIC 170 uses an RTQ2078; and the serializer Serdes 140 uses a MAX96701.

[0042] The connector 160 uses an RFCOAX coaxial cable and forms a point-of-concept (POC) circuit with inductors L1 and L2 and resistor R1. A low-pass filter separates the power signal from the high-speed serial signal. The power management chip PMIC 170 has three outputs, providing operating voltages of 1.1V, 1.8V, and 2.8V to power the sensor 120, the graphics signal processor ISP 130, and the serializer Serdes 140.
