Bosch and Daimler have reached a milestone on the way to automated driving: the two companies have now obtained approval from the relevant authorities in Baden-Württemberg for their automated parking system in the Mercedes-Benz Museum parking garage in Stuttgart. The automated valet parking service is accessed via a smartphone app and requires no safety driver. This makes it the world’s first fully automated driverless SAE Level 4 parking function to be officially approved for everyday use.
“This approval from the Baden-Württemberg authorities sets a precedent for obtaining approval in the future for the parking service in parking garages around the world,” says Dr. Michael Hafner, the head of drive technologies and automated driving at Daimler AG. “As a pioneer in automated driving, our project paves the way for automated valet parking to go into mass production in the future.”
“This decision by the authorities shows that innovations like automated valet parking are possible in Germany first,” says Dr. Markus Heyn, member of the board of management of Robert Bosch GmbH. “Driverless driving and parking are important building blocks for tomorrow’s mobility. The automated parking system shows just how far we have already progressed along this development path.”
Playing it safe: two partners with a common objective
From the very beginning, Bosch and Daimler’s top priority for the driverless parking service was safety. Since there is as yet no official approval process for automated driving functions that do not require a driver, the local authorities – the Stuttgart regional administrative authority and the state of Baden-Württemberg’s transportation ministry – oversaw the project along with experts from the German technical inspection service TÜV Rheinland from the outset. Their aim was to assess the operating safety of the automotive and parking-garage technology.
The result is a comprehensive safety concept with appropriate testing and approval criteria that can be applied beyond this pilot project. In the concept, the developers defined how the driverless vehicle detects pedestrians and other cars in its path and reliably comes to a halt when it encounters an obstacle. They also set up secure communications between all system components and took steps to ensure the reliable activation of the parking maneuver.
The technology behind driverless parking
Drive in to the parking garage, get out, and send the car to a parking space just by tapping on a smartphone screen – automated valet parking has no need for a driver. Once the driver has left the parking garage to go about their business, the car drives itself to an assigned space and parks. Later, the car returns to the drop-off point in exactly the same way. This process relies on the interplay between the intelligent parking garage infrastructure supplied by Bosch and Mercedes-Benz automotive technology. Bosch sensors in the parking garage monitor the driving corridor and its surroundings and provide the information needed to guide the vehicle. The technology in the car converts the commands from the infrastructure into driving maneuvers. This way, cars can even drive themselves up and down ramps to move between stories in the parking garage. If the infrastructure sensors detect an obstacle, the vehicle stops immediately.
