fety and Security Concept for an Automated Parking Service Automated parking systems that assume the control of a passenger car at the entrance to a parking garage, park it driverless, and drop it off again on demand will be one of the first autonomous driving applications to go into series production. Bosch and Daimler marked a world first in summer 2019 by obtaining an official approval to operate an automated valet parking service. The basis of the valet parking is a comprehensive five-pillar safety and security concept in order to attain SAE level 4, which is explained here in detail.

With Automated Valet Parking (AVP), a service for driverless parking, the driver simply pulls up at the entrance of the parking garage, exits the vehicle, and activates the automated parking function via smartphone. Without any further driver input – and guided by the infrastructure – the driverless vehicle then moves off automatically and parks in an assigned space. When the driver is ready to depart, the passenger car pulls up again in the same manner. Bosch and Daimler initiated a joint development project in 2015 to get this AVP concept ATZ worldwide 12|2020

off the ground in a pilot application. In 2017, two years after the project started, the partners were able to unveil AVP in the parking garage at Stuttgart’s MercedesBenz Museum, representing the first “real-life” operation of its kind. Another crucial step toward industrializing the system then followed in summer 2019: As the world’s first fully automated, driverless parking function, the AVP system developed by Bosch and Daimler was granted SAE level 4 (high automation) approval for everyday operation, removing the need for the human monitoring that would otherwise be required. This milestone was made possible by the close collaboration between the devel opment partners Bosch and Daimler with the team of auditors from the German technical inspection association TÜV Rheinland, the Stuttgart Regional Council, and the German State of BadenWürttemberg’s Ministry of Transport. When applying for official approval from the Stuttgart Regional Council, the main condition was to demonstrate that the system would operate safely under all conditions and that the vehicle would independently transition to a safe state in the event of a fault. The approved safety and security concept is based on a holistic approach that covers all critical aspects of AVP operation and features a five-pillar structure, FIGURE 1. With this aim in mind, all conceivable scenarios that could occur during dayto-day use were thoroughly analyzed and considered in the safe and secure function of the AVP system for normal operation. Appropriate countermeasures were also developed to address the potential sources o
