With the popularity of car cameras and large screens, how can we lead the upgrading of video technology through innovative bus connections?
With the acceleration of automobile electrification process and the continuous improvement of automatic driving function, there are more and more electronic components in automobiles. Many electronic devices face more and more challenges in efficient information exchange. For example, the enhancement of the automatic driving function requires more vehicle sensors, and the point-to-point communication of the transmission cannot meet the requirements, so advanced bus technology must be adopted. In particular, with the popularity and application of car cameras in automatic driving and the standard configuration of high-definition large screens in cars, the demand for stable and reliable high-definition video connections has increased dramatically.
The traditional vehicle bus realizes the communication network interconnection of vehicle equipment or vehicle instruments at the bottom of vehicle network. Four vehicle buses occupy the mainstream, mainly including can bus, LIN bus, FlexRay bus and most buses. However, these buses, which have been on the market for more than ten years, are facing some shortcomings in terms of new functions of automotive video applications. Among them, the communication connection of the camera is one of the difficulties in application. Car camera is one of the key sensors to promote the development of autonomous vehicles. With the continuous application of new applications, the number of car cameras is also increasing rapidly. In addition, as the application of cameras has shifted from high-end cars with a low ownership rate to a larger mainstream car market, the usage rate of cameras is also increasing.
As the number of cameras increases, the demand for higher resolution also increases. Automobile manufacturers need to ensure that new models use new display technologies so that their display systems remain old for as long as possible. Car manufacturers continue to improve the size and resolution of on-board displays. To display camera images on these larger, higher resolution displays, they require a higher resolution camera. Using existing standard definition cameras will result in a very poor user experience. In order to provide a better customer experience, they need to use high-definition cameras. Adding these cameras requires additional costs - not only increases the number of sensors and the cost of image processing, but also transmits video data from the camera to the processing unit through the vehicle harness.
It seems that more cables are needed for the connection of on-board cameras. However, considering that the cost of vehicle harness is only the third place among vehicle components, engine and chassis, its weight ranks the third in the selection of cables and connectors in China. With the continuous increase of these harnesses in the automobile, there are more and more problems in the automobile production line, and any additional production steps will further increase the cost. In addition, with the popularity of electric vehicles, the additional weight of the harness will directly affect the vehicle's mileage.
Carleader has produced a wireless car camera monitoring system CL-S760TM-AW / DW, which includes a 7-inch high-resolution LCD screen and a multi-channel camera, which can be connected by digital wireless or analog wireless. It only needs to be connected to the power supply without wiring, and can be applied to various vehicles through simple installation, which can solve this problem well.
