1. What is an EDR (Event Data Recorder) for vehicles? The EDR (Event Data Recorder), also known as the "black box" of cars, is a specialized data recording device installed on cars. Its core functions include: firstly, data recording, which can record key vehicle operation data such as vehicle speed, braking status, steering angle, and some devices can also record the working status of driving assistance systems; The second is accident analysis, which restores the accident process through data before and after the collision, helping to distinguish between driver operation errors or vehicle failures, and providing objective basis for judicial liability determination and insurance claims; The third is tamper proof and storage. Data is stored in tamper proof EEPROM modules, and some vehicles can transmit data through remote systems to ensure information reliability. Unlike dash cams, EDR records vehicle dynamic data and driving operations, and records them when specific events (such as sudden speed changes) are triggered. Its core function is to analyze the cause of accidents and determine responsibility; The driving recorder records video and audio continuously, mainly for the retention of visual evidence. In terms of regulations, starting from January 2022, Chinas "Technical Conditions for Motor Vehicle Operation Safety" clearly stipulate that newly produced passenger cars must be equipped with an EDR system, which has now become a standard for vehicle safety. It has a wide range of application scenarios, and in accident investigations, the vehicle state at the moment of collision can be restored through data; In terms of vehicle safety improvement, manufacturers can optimize safety system design based on EDR data; In insurance claims, it can reduce disputes caused by information asymmetry and quickly assess losses. In short, EDR has improved the traceability of traffic accidents through technological means and is an important component of contemporary automotive safety systems.

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: EDR can record operational data of the vehicle in three stages: before collision, during collision, and after collision, including speed, ABS status, steering wheel angle, airbag status, vehicle braking status, etc. These data can effectively restore the true state before and after the accident, providing objective basis for accident analysis.

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.
