Evaluation Rules for Valet Parking Assist
This test technical regulation is applicable to valet parking assist system.
The valet parking assist system refers to a parking assist system that needs to set a route
in advance and can complete cruise, park in or park out according to the route.
The vehicle under evaluation needs to declare whether it has one-button summoning
capability for outdoor parking lot, one-button summoning capability for indoor parking
lot, one-button parking capability for outdoor parking lot and one-button parking
capability for indoor parking lot:
1) If it has one-button summoning capability for outdoor parking lot, then conduct
the evaluations of items 1, 2, 3, 4, 5, 6, 7 in Table 1-1.
2) If it has one-button summoning capability for indoor parking lot, then conduct the
evaluations of items 8, 9, 10, 11, 12 in Table 1-1.
3) If it has one-button parking capability for outdoor parking lot, then conduct the
evaluations of items 13, 14, 15, 16, 17 in Table 1-1.
4) If it has one-button parking capability for indoor parking lot, then conduct the
evaluations of items 18, 19, 20, 21 in Table 1-1.
Only when the score of B.1 Basic parking assist is ≥70 points can the test of this
regulation be carried out.

2.3 Terms and definitions
Vehicle Under Test
A vehicle that is capable of continuously controlling both lateral and longitudinal
motion and is tested in accordance with this test procedure.
Vehicle Target
The vehicle target specified in this test technical regulation.
Time To Collision
The time it takes for the vehicle under test to collide with the vehicle target, mannequin
target, bicycle target, or scooter target while maintaining the current state of motion.
Time Gap
The time required for the vehicle under test to travel at the current speed and reach the
target position at the current moment.
Set Speed
The expected speed (displayed speed) of the vehicle when the driving assist system is
activated.
Desired Speed
After setting the vehicle speed, the maximum stable vehicle speed that the system can
achieve.
Number of parking
During the process of parking the vehicle, when the gear position is shifted to Gear R
and the vehicle is moving, it is counted as the first parking. During the parking process,
when the gear position is switched from R to D or from D to R, they should be counted
as one parking respectively.
Average speed of cruising section
It refers to the average vehicle speed of the cruising section calculated based on the
running time of the section of a 30m-long continuous road intercepted by the vehicle
on the through-lane after it runs stably.
2.4 General
This part describes the test methods for valet parking.
2.5 Test conditions
2.5.1 Test site conditions
1) The test road needs to be dry. The surface is free of visible moisture. The surface
is smooth and solid.
2) The test road surface requires compaction and no irregularities that may cause the
sensor to work abnormally (such as large inclinations, cracks, manhole covers, or
bolts with reflective capabilities).
3) Lane lines can be white solid lines, white dotted lines, yellow solid lines and
yellow dotted lines, meeting the requirements of GB 5768.3.
Select the outdoor parking lot of China Automobile Center (or other closed outdoor
parking area where the valet parking function can be activated), and the parking
building of China Automobile Center (indoor parking lot) as the test site.
2.5.2 Test weather conditions
1) The weather is dry, without raining or snowing.
2) The visibility in the horizontal direction of the outdoor parking lot is not less than
1 km.
3) The wind speed is not greater than 10 m/s.
4) For tests conducted under natural light conditions, the lighting conditions should
be consistent throughout the test area. The light intensity should not be lower than
2000 Lux. The test is not carried out towards or away from direct sunlight.
5) The illuminance of the indoor parking lot should not be less than 30 lux. There is
no obvious shadow on the test road. Parking spaces are clearly marked.
2.5.3 Equipment requirements
2.5.3.1 The test equipment should satisfy the sampling and storage of dynamic data.
The frequency of sampling and storage is at least 100 Hz. The DGPS time is used for
data synchronization between the vehicle target and the vehicle under test.
2.5.3.2 Data acquisition and object control accuracy
The data acquisition accuracy of the target object and the vehicle under test during the
test should at least...
