is earlier.
4.3 Data recording requirements for type II system
During the activation of the automated driving system, the type II system shall record
at least the following data:
a) Record data elements that meet the requirements of Table 1 at the real-time
recording start point;
b) Real-time continuous recording of data elements that meet the requirements of
Tables 2 ~ 5;
c) Timestamp events: When the automated driving system enters the activation state,
exits, issues an intervention request, starts to execute the minimum risk strategy,
ADS serious failure and vehicle serious failure occur, or the user operates the
ADS to exits device in accordance with the provisions of GB/T 44721, the
The data recorded by the automated driving data recording system shall be stored in the
vehicle-side non-volatile memory.
