China drafted two mandatory parking standards, one of them with a safety case annex

Two of the five mandatory national standards China put out for comment on October 20 cover parking automation, and together they move the field from a recommended performance standard to compulsory safety requirements.

The first, on safety requirements for parking combined driving assistance systems, replaces GB/T 41630—2022 on intelligent parking assistance performance requirements and test methods. The draft carries two normative annexes its predecessor did not: one setting functional safety and safety-of-the-intended-functionality requirements, and one setting the corresponding description requirements. The draft’s own change list records that functional safety requirements were modified and safety-of-the-intended-functionality requirements added, alongside data recording requirements and simulation testing.

The second, on safety requirements for automated parking systems, has no predecessor. It is a new mandatory standard, and its structure is the notable part: a normative safety case annex, a chapter of safety case inspection, and a confirmatory dynamic test whose cases are selected on the basis of that safety case.

In two places the draft names an over-the-air update as the corrective action available to a manufacturer — once for updating the system design in response to systematic faults, and once in response to functional insufficiency, where it lists an operating design domain update alongside it.

Both documents run to well over a hundred pages with their test methods and annexes included. Comments on all five drafts close on December 19.
