1. The meaning of digital data recorder
The meaning of digital data recorder is a digital data recorder. Here is a brief introduction to digital data loggers: Function: A digital data logger is a device specifically designed for collecting, storing, and managing digital data. It can receive data from various sensors, instruments, or other digital signal sources and store it in digital form in internal memory. Application: This type of device is widely used in industrial monitoring, automotive testing, aerospace, scientific research, and other fields to record and analyze data changes in various dynamic processes. Advantages: Compared with conventional analog recorders, digital data recorders have higher accuracy, larger storage capacity, and stronger data processing capabilities. In addition, they also provide more convenient data export and analysis functions, enabling users to process and analyze data more efficiently.
2. Technology | What is the mandatory "black box" to be installed on vehicles next year? What impact does it have? The "black box" that will be mandatory for vehicles next year is EDR (Event Data Recorder), which is an automotive event data recording system. Its function is to record key data before and after vehicle accidents, assist in accident liability determination, and promote the development of intelligent connected vehicles, but it may increase manufacturing costs. The specific impact is as follows:
1. Definition and Function of EDR. The full name of EDR is Event Data Recorder, which is a car event data recording system. Its function is similar to the Flight Data Recorder (FDR) on airplanes, and it is called the "black box" of cars. Recording key data of vehicle operation
Secondly, the difference between EDR and dash cam (DVR) is that the recording content is more comprehensive: dash cam mainly records the external image information of the vehicle, while EDR records the vehicle status more comprehensively, covering key data of vehicle operation.
. Advantages in the context of autonomous driving: With the popularization of autonomous driving assistance technology today, relying solely on driving recorders to record the internal and external environment of a vehicle when an accident occurs in autonomous driving mode lacks sufficient information support and cannot fully restore the scene at that time. EDR can provide more detailed data to help regulatory authorities more intuitively determine accident liability.Third, the popularity of EDR is relatively low in China: Currently, the popularity of EDR in the domestic market is not high, and it is mostly used in the commercial field.
. Data shows that in 2020, only 1.3571 million new cars in China were equipped with EDR devices, with a market penetration rate of 7.12%. The overseas popularization speed is relatively fast: the EDR popularization speed in overseas markets is better than that in China. For example, the US automotive safety regulations require that all vehicles sold within the US must be equipped with EDR after September 2014. 4. The positive impact of mandatory install
