AVP test environment for autonomous driving use cases
Anritsu Corporation has developed a test and simulation environment for Automated Valet Parking (AVP) in collaboration with dSPACE GmbH and Apposite Technologies LLC. A demonstration was held as part of the 5GAA Member Symposium event in Malaga, Spain in October 2022.
AVP enables valet parking to be done automatically, without any driver in the vehicle. AVP Technical Report Version 1.0 was released by 5GAA in June 2022, and a wireless communication (Type-2) operation scheme linked with parking garage infrastructure and users’ smartphones was proposed.
AVP is being developed as an autonomous driving use case which can be deployed in the short term. AVP Type-1 autonomous driving vehicles require expensive high-performance computing and sensing, while AVP Type-2 communication-cooperative vehicles do not require such installations, reducing vehicle costs and making implementation easier.
Since AVP Type-2 requires highly reliable end-to-end communications, a test system needs to evaluate QoS management and impairment effects in the IP layer. The wireless connectivity environment also needs to be evaluated. The test system implementation set up a digital twin environment incorporating both virtual and real devices. This allows the system tests and certification required to improve the reliability of AVP Type-2 to be started before the actual devices are available.
The base station simulator Anritsu MT8000A radio communication test station used in the demonstration provides network simulation for 5G radio access technology and provides a development evaluation and certification test environment for automotive use cases such as Telematics, Infotainment, and V2X.
A software-based tool from dSPACE integrates and simulates environment/infrastructure/sensor/vehicle information only on a PC. In this demonstration, AVP System is installed in it.
Vehicle motion control commands (VMC) generated by the AVP System are transmitted to the OEM Application, which displays the state of vehicle control, via 5G communication using Anritsu’s 5G base station simulator.
VMC commands pass through the Apposite Network emulator on the way to OEM Application. IP data delay and data packet loss are added by the emulator, and so vehicle control becomes unstable due to its influence in the OEM Application. AVP developers design control systems and networks to keep vehicle control stable.
Sample simulation image: A virtual vehicle that has received VMC (Vehicle Motion Control) commands across the 5G network is automatically driving in a parking lot according to control instructions sent by the parking garage.
Automotive OEMs, Tier 1 suppliers, and mobile network operators have shown great interest in the demonstration, and we will continue to develop this simulation environment and contribute to the realization of AVP.
