Thanks to an automated guided vehicle parking system, Bosch and Daimler have reached a milestone on the way to automated driving: For the automated parking system in the parking garage of the Mercedes-Benz Museum in Stuttgart, the two companies have now been approved by the responsible authorities in Baden-Württemberg. The automated ancestor and parking service is accessed via smartphone app and does not require a security driver. It is thus the world’s first fully automated and driverless parking function according to SAE Level 41, which is officially approved for everyday use.
To be on the safe side: Two partners, one common goal
Since automated driving functions that do not require a driver have yet to be approved, the local authorities – Stuttgart Regional Council and Baden-Württemberg Ministry of Transport – and TÜV Rheinland’s experts accompanied the project from the start. The aim was to assess the safe operation of vehicle and parking garage technology.
The result is a comprehensive security concept with corresponding test and approval criteria, which can also be used beyond the pilot project. On the one hand, the developers have defined how the driverless vehicle recognizes pedestrians and other cars in the driving way and reliably stops them in the event of an obstacle. In addition, a secure communication of all system components with each other and the reliable activation of the parking process was implemented.
Driverless parking – the technology
Drive into the parking garage, get out and park the car for parking with a click on the smartphone – the automated parking service works without the driver. While he is already leaving the parking garage and can devote himself to other things, the car drives autonomously to an assigned parking space and parks. Likewise, the car comes on request again pulled up. The intelligent parking garage infrastructure from Bosch is combined with Mercedes-Benz vehicle technology. Bosch sensors in the parking garage monitor the driving corridor and its surroundings and provide the information needed to control the vehicle. The technology in the car converts the commands of the infrastructure into driving maneuvers. In this way, the cars can also ramp up and shut down independently and change floors within the parking garage. If the infrastructure sensors detect an obstacle, the vehicle stops immediately.
Milestones of the project
After Bosch and Daimler launched the development of fully automated and driverless parking in 2015, the pilot solution in the parking garage of the Mercedes-Benz Museum in Stuttgart reached an important milestone in summer 2017: Automated Valet Parking was presented to the public for the first time in real traffic , The premiere was followed by an intensive test and commissioning phase. Since 2018, visitors to the museum have been able to experience the valet service live in the presence of trained security personnel and share their experiences. As part of the pilot project, lighting concepts were also tested on the vehicle. This turquoise light signals mark the automated driving mode and inform passers-by and other road users that the vehicle is independently on the road. The findings were also taken into account in the recently adopted SAE standard (SAE 3134). With the final approval by the authorities, Bosch and Daimler are now achieving another important milestone: interested parties will soon be able to experience the innovative ascent and parking service in day-to-day operation of the parking garage of the Mercedes-Benz Museum and without further monitoring by a safety driver.
