Session A4: Autonomous Applications

Empowering Automated Driving with Bosch
Markus Langer, Robert Bosch GmbH
Date/Time: Thursday, Sep. 19, 4:46 p.m.

Introducing the VMPS: Empowering Automated Driving with Bosch
Bosch, a leading supplier in the automotive industry, offers a comprehensive range of products for the ADAS market, including components such as radar, camera, and ultrasonic sensors, as well as complete system solutions for automated driving. One of the newest products is the VMPS (Vehicle Motion and Position Sensor), which provides customers with a safe and reliable source for GNSS-based absolute positioning for automated driving systems.
The VMPS is a remarkable product that offers customers a safe and reliable source for GNSS-based absolute positioning in automated driving systems. Designed to meet the highest standards, the VMPS features a dual-frequency, multi-constellation GNSS receiver (L1/L2 or L1/L5) and a highly accurate MEMS IMU. By leveraging wheel-speed information from the vehicle, the VMPS delivers a precise and accurate PVTA (position, velocity, time, and attitude) solution.
To ensure utmost accuracy, the VMPS is complemented by a cloud-based GNSS correction service, enabling PPP-RTK based positioning within centimeter range. With its exceptional performance, the VMPS not only offers accuracy but also ensures safety and integrity with its machine-learning enhanced protection level (PL) and integrity information.
Bosch takes pride in being the first supplier to introduce a safe GNSS solution for the automotive market, setting the standards for safety and integrity for automotive applications. Leading OEMs have already embraced the VMPS, with Mercedes utilizing it to release the world's first Level 3 driver assistance functionality in the iconic S-Class.
Our market analysis and forecast indicate a growing demand for safe GNSS positioning not only in the Level 3/4 market but particularly in the Level 2+ segment for automated driving. To meet these evolving market needs, Bosch has significantly enhanced the VMPS's key performance parameters. Since the end of 2023, Bosch offers a comprehensive one-box turnkey solution package, complete with a single-source GNSS correction service provider for global availability in major markets. (EU, NA, CN). Roll out in other Asian or Arabian countries is either planned or possible based on customer needs.
With improved key performance indicators, such as 10cm @1sigma PPP-RTK based GNSS/INS/WSS absolute positioning (lateral/longitudinal) and 0.01m/s @1sigma velocity (lateral/longitudinal), the VMPS ensures exceptional accuracy ensuring a high availability at the same time. Moreover, our product offers an integrity risk of 10^-5/h for an alarm limit of 3m, meeting the stringent safety requirements of the automotive industry. At the same time the VMPS adheres to the automotive standard ISO26262 and offers an ASIL (Automotive Safety Integrity Level) B
During the lecture, the focus will be on three main KPIs of the VMPS: performance, safety/integrity (SOTIF), and availability. The lecture will explore what makes GNSS-based localization safe in the context of the automotive industry and how it differs from avionics. Coming from use cases and market needs not only the product itself but also the VMPS as part of a world-wide system will be discussed.
Bosch has conducted extensive test drives and collected thousands of hours of data for development and product release tests. However, achieving a target integrity risk of 10^-5/h requires more than just test drives. The lecture will delve into the various pillars that contribute to the release of a safe GNSS-based system. Fault tree analysis and other classical safety tools need to be combined with simulation, hardware in the loop tests. Environmental conditions, spoofing, and jamming need to be considered.
Since the new improved VMPS integrity concept includes machine-learning and data-driven enhancements also new standards like ISO CD PAS 8800 (Safety and Artificial Intelligence) come into focus.
The lecture will conclude by addressing the handling and evaluation of an extensive test drive database in context of a release process and showcasing the capabilities of a state-of-the-art safe GNSS positioning device. Finally, Bosch will provide insights into the future of safe GNSS and highlight current market trends, such as the shift towards software as a product versus one-box solutions.
