Chinese parking standards include mandatory GB standards for parking assist performance and remote parking, recommended GB/T standards for automatic parking and automated valet parking, QC/T industry standards for ultrasonic sensors and surround-view cameras, and T/CSAE group standards for parking function classification.

Parking functions are classified from Level 0 (parking warning only) through Level 5 (automated valet parking). Intermediate levels include semi-automatic APA with driver-controlled pedals, full APA with system-controlled steering and braking, RPA with out-of-vehicle remote control, and HPA memory parking on learned routes.

Remote parking assist requires a dead-man switch with continuous press operation, stop-on-release response under 300ms, immediate stop on communication loss, a remote range limit under 6 meters, and speed limits of 5 km/h forward and 3 km/h reverse. Functional safety targets ASIL B/C.

Typical configurations require at least 12 ultrasonic sensors with 0.15-5.0m range and 360-degree coverage, plus four surround-view cameras with 190-degree FOV and minimum 1280x960 resolution. Advanced functions like AVP may add corner radar, lidar, and V2X for infrastructure communication.

Test scenarios cover parking space recognition with pass rates above 95% for standard spaces, parking execution within time and position accuracy limits, static and dynamic obstacle detection including pedestrians and children, and environmental conditions such as low light, wet surfaces, and slopes.
