c) Shall be able to control the vehicle to cruise through straight roads, curves, intersections, speed bumps, etc., and cruise through other scenarios according to the design operational conditions declared by the manufacturer;

d) When the system is parking in on-street parking slots, the vehicle cruise control shall comply with the relevant provisions of national laws and regulations regarding motor vehicle road driving.

4.2.2 Human-computer interaction requirements

Users can interact with the system via on-board or mobile terminals. In addition to meeting the requirements of Chapter 7 of GB/T 44721-2024, the system's human-computer interaction capabilities shall also meet the following requirements.

a) When the vehicle is unoccupied and the system is active, upon receiving a remote braking command from the user or the parking management system, the system shall be able to control the vehicle to brake until it stops, provided that safety is ensured;

b) After the vehicle executes a remote braking command, the system shall resume operation only after confirmation by the user or the parking management system;

c) When the vehicle is unoccupied and the system is active, a Class I system shall provide the user or the parking management system with the vehicle's operational status, and a Class II system shall provide the user or the parking management system with the vehicle's operational status and relative location information.

Note: a) and c) apply only if the relevant national laws and regulations allow in-vehicle unmanned operation.

4.2.3 Self-inspection and diagnosis requirements

The system shall at least have the following self-inspection and diagnosis functions, and shall perform self-inspection before system activation and continuous fault diagnosis during operation, providing operators with corresponding text or voice prompts regarding fault information.

a) Check whether the main control and execution components are operating normally;

b) Check whether the relevant sensing components are operating normally;

c) Check whether the current vehicle status affects system operation.

4.2.4 System critical state transition requirements

4.2.4.1 For a system to switch from a non-ready state to a ready state, at least the following conditions shall be met.

-- System self-inspection is passed;

-- The design operational conditions declared for the automatic parking function are met.

4.2.4.2 The system shall switch from the ready state to the non-ready state when one of the following conditions is met.

-- The system is diagnosed a fault affecting the normal operation of the automatic parking function;

-- The design operational conditions declared for the automatic parking function are not met.

4.2.4.3 When the vehicle is started (powered on) (except for engine idle start-stop during cruise control), the system shall not directly enter the active state, and the system shall only be allowed to switch from the ready state to the active state after confirmation by the user or the parking management system.

4.2.4.4 After receiving a remote braking command, the system shall switch from executing the dynamic driving task of parking to executing the remote braking state.

4.2.4.5 When the system issues an intervention request, but the user or the parking management system does not respond to the intervention request within the specified time, the system shall switch from the active state to the state of executing the minimum risk manoeuvre.

4.2.4.6 The system shall allow switching from the state of executing the minimum risk manoeuvre to the minimum risk condition only when the vehicle is completely stationary.

4.2.4.7 After the system reaches the minimum risk condition, it shall meet at least the following conditions to re-enter the ready state.

-- The design operational conditions declared for the automatic parking function are met;

-- The user or the parking management system sends a confirmation message.

4.3 Functional safety and SOTIF requirements

The functional safety and safety of the intended functionality of the system shall comply with the requirements of Appendix A of GB/T 44721-2024.

5.1 Parking requirements

5.1.1 Parking time

Tested in accordance with 7.2.1 and 7.2.2, the time required for a vehicle equipped with a Class I system to park in and out of a parking slot shall not exceed 50 seconds;

Tested in accordance with 7.2.1, the time required for a vehicle equipped with a Class II system to park in a parking slot shall not exceed 50 seconds.

Note 1: Parking-in time refers to the time taken from the moment the vehicle shifts into reverse gear to the completion of the parking-in maneuver (e.g., when the vehicle shifts to a non-driving gear or the system issues a parking-in completion notification).

Note 2: Parking-out time refers to the time taken from the moment the vehicle shifts from a non-driving gear to a driving gear to the completion of the parking-out maneuver (e.g., when the vehicle shifts to a non-driving gear or the system issues a parking-out completion notification).

Note 3: Unless otherwise specified, the test scenarios specified in this document are all about parking the rear of the vehicle into the parking slot and parking the front of the vehicle out of the parking slot.
