In the car circle, the first big thing at the beginning of 2022 must be known to many friends who are ready to buy or pick up a car. From January 1, 2022, newly produced passenger cars in China will be required to be equipped with an automotive event recording system known as Event Data Recorder, or EDR for short.

EDR is also known as the "black box on the car", and the black box must be familiar to those who are fans of aircraft and aviation. The function of EDR is actually similar to the black box on an airplane.
The black box is actually one of the most important components of the aircraft. When a plane encounters a so-called air crash, the black box on the plane comes in handy.
Black boxes are actually used as a tool to record various data in various airports. When a dangerous situation leads to an aircraft crash, the causes and consequences of the dangerous situation can be restored and the wrecked aircraft can be recovered through the flight trajectory and positioning, operation instructions, communication voice records, and record preservation of various dynamic parameters of the aircraft at the moment.
Cars will be forced to install EDRs in principle equivalent to black boxes on airplanes. Its appearance is actually to record the vehicle dynamic information in the unexpected situation. So speaking of this, there are many friends to ask, the driving recorder on the market has been very popular, why do you have to force a DER?
In fact, DER is not equivalent to the dashcam, EDR in the data recording is for the dynamic operation of the vehicle data recording, when the vehicle accident, EDR will record the speed, ABS, seat belt, braking force, throttle travel and other data changes. The driving recorder only uses the appearance of the picture to determine the occurrence of the accident.
Therefore, for vehicles that are out of control and cause accidents or serious accidents caused by serious quality problems in the vehicle, EDR can truly and objectively feedback the dynamic information of the vehicle in order to judge the authenticity of the facts.
When it comes to the popularity of EDR, with the continuous development of automotive intelligence and the continuous innovation of new energy driving forces. In recent years, there have been few news cases of car safety issues. Often in the retrospective reports of these news cases, due to the lack of data authenticity, the dangerous facts caused by them can often not be objectively restored.
Therefore, for the determination of responsibility involved in vehicle safety accidents, it is often the case that the owners of the accident and the dealers or car manufacturers form a two-faced faction, and both sides hold what they see. The popularity of EDR is of vital importance to today's automotive safety issues.
