In recent years, the enthusiasm of autonomous driving has brought people’s attention to vehicle camera imaging systems. Recently, the term “vehicle regulation level” has once again brought attention to car imaging systems. Some time ago, Black Sesame and Horizon released their own car-grade chips, and Mobileye and NVIDIA also have relevant car-related chips. For users, the car grade also means more safety and more mature technology. The camera imaging system functions as the main function in these chips. As shown below, the camera function in the car is rich and diverse. So what exactly is a car regulation level? What are the main car regulations related to imaging? What are the requirements for the imaging system? How to carry out related design development and certification for different functions? We hope to introduce this related content in a series of articles.
Main car regulations
First of all, it must be clarified that the car regulations are not a single standard specification, but a series of related (international) national standards. Due to the safety of the car, if relevant components and systems can be used in the car, and the car must finally pass the corresponding standards and specifications on the road. Some of these specifications are international norms such as the resumes of the United Nations or the International Standards Organization, and there may be differences in regional norms in different regions. For example, China, the United States, Europe, and Japan often have some national or local regulations. Even when national regulations are missing, some provinces currently have different regulations for ADAS and autonomous driving. This article mainly introduces international standards, others are introduced later. In terms of international regulations, imaging chips are generally mentioned, and the common ones refer to the car regulations in the following figure (this is the main part but not comprehensive, in fact, there are many car-related specifications). There is no description of some specifications related to the image quality of the imaging system, but the development of imaging systems must also follow the corresponding specifications, so we first introduce this part.
