GB/T 44719-2024Intelligent and connected vehicle - Methods and requirements of road test for automated driving functions (English PDF)

4.3.1 Test personnel

4.3.1.1 During the test, the test operation staff and on-board test staff shall not cause the system to issue an intervention request due to their personal behavior.

4.3.1.2 During the test, the test operation staff monitors the vehicle under test for safety and takes over immediately when the system issues an intervention request, and immediately intervenes in the vehicle's driving when the system executes the minimum risk strategy.

4.3.1.3 During the test, the on-board test staff shall record whether the vehicle meets the test requirements based on the test results, and record the moment when the vehicle under test fails to meet the relevant requirements of

5.2 through the test equipment.

4.3.2 Test equipment

4.3.2.1 Event time record The test equipment shall support the on-board test staff to record test operation staff intervention, test operation staff takeover, vehicle under test intervention requests, minimum risk strategy status display, and the time when the vehicle under test does not meet the test pass requirements.

4.3.2.2 Test record contents The test equipment shall be able to record at least the following during the test.

a) Control mode of the vehicle under test, such as manual driving mode, automatic driving mode, etc.

b) Video information of traffic conditions around the vehicle under test.

c) Motion state parameters of the vehicle under test: 1) Test timeline; 2) Location information of vehicle under test; 3) Longitudinal speed of vehicle under test; 4) Lateral velocity of the vehicle under test; 5) Longitudinal acceleration of vehicle under test; 6) Lateral acceleration of vehicle under test; 7) Yaw velocity of vehicle under test.

d) Video and voice monitoring information of the test operation staff and human- machine interaction status (test operation staff's face, instrument panel, steering wheel, central control screen, pedals, etc.).

e) Test mileage and duration: 1) Record the test mileage of the vehicle under test in different road environments; 2) Record the test duration of the vehicle under test in different road environments.

4.3.2.3 Test equipment accuracy The test equipment shall meet the following requirements:

a) The frequency of motion state acquisition and storage is not less than

b) The resolution of the video acquisition device is not less than (1920×1080) pixels. The video sampling frame rate is not less than 30 f/s;

c) The speed acquisition accuracy is not greater than

0.1 km/h;

d) The distance acquisition accuracy is not greater than

0.1 m;

4.4 Test time

4.4.1 The test shall be conducted in road environments where the autonomous driving function of the vehicle under test can be activated. The total effective test duration between different types of road environments shall be recorded independently.

4.4.2 If the autonomous driving function of the vehicle under test can be activated under illumination conditions below 50 lx, night tests shall be carried out. NOTE: The daytime test period is the period from sunrise to sunset. The nighttime test period is the period from sunset to sunrise the next day. The sunrise and sunset times are subject to the information released by the local meteorological bureau.

4.4.3 The total effective test duration accumulated after several single continuous tests shall be at least 72 h. One of the following conditions shall be met: setting plan. NOTE: The set plan refers to the test plan set according to the autonomous driving function of the vehicle under test and the test road in a single continuous test.

5.2.1 Function activation

5.2.1.1 Except when the engine starts and stops automatically, the vehicle under test shall meet one of the following requirements after each ignition (power-on):

a) The autonomous driving function is not activated;

b) The autonomous driving function is in a ready state under conditions that comply with its autonomous driving function description materials. NOTE: Materials describing the autonomous driving function include but are not limited to design and operating condition description documents, autonomous driving system operation manuals, and other materials.

5.2.1.2 The vehicle under test shall have a dedicated control method to activate the automatic driving function. When the test operation staff activates the automatic driving function through a dedicated control method, the vehicle under test shall meet the following requirements:

a) If the autonomous driving function of the vehicle under test is in an inactivated state where it can be activated, the autonomous driving function is activated;

b) If the autonomous driving function of the vehicle under test is in an inactivated state and cannot be activated, the autonomous driving function will not be activated.

5.2.2 Performing dynamic driving tasks

5.2.2.1 The autonomous driving function of the vehicle under test is activated, and no traffic accidents for which the vehicle under test is responsible shall occur when performing dynamic driving tasks.

5.2.2.2 The autonomous driving function of the vehicle under test is activated and the following requirements shall be met when performing dynamic driving tasks:

a) Do not cause trial operators to perform non-strategic interventions; NOTE: Strategic intervention refers to the test operation staff's intervention in the driving of the vehicle under test due to reasons such as itinerary planning and destination selection.

b) Except when changing lanes, do not ride or run over the lane dividing line or lane edge line;

c) When encountering a stop signal, the outline of the vehicle under test does not stop beyond the stop line;

d) The speed does not exceed the speed limit;

e) Except in emergency situations, do not drive or park in the emergency lane;

f) Do not overtake or turn around in dangerous sections of the road;

g) Do not drive in violation of traffic light instructions;

h) Do not drive in violation of road traffic signs and markings;

i) Give way to pedestrians and non-motor vehicles when passing through crosswalks;

j) Pass through intersections according to the right of way;

k) Correctly use lighting and light signal devices including but not limited to low beam lights, turn signals, brake lights, hazard warning signals, and horns;

l) Other road traffic rules and requirements.
