"Bosch Connected and Virtualized Development: Use of In-Vehicle Data to Optimize and Validate Braking Systems"

"Virtual development of electronic braking systems Value creation through in-vehicle data and cloud services Connected cars generate in-vehicle data from its electronic control units and sensors about how they are used, where they are, and how they feel. The amount of in-vehicle data will grow further exponentially, with progress in higher levels of driving automation, personalization and electrification. Therefore, exploiting the chances of generated in-vehicle data will become a key theme for the value creation and new business models in the automotive and mobility industry. While this will only happen in small steps, it will come quickly and will have a huge and lasting impact on both industries. Bosch connected braking systems Connected braking systems (CBS) is a new and connectivity-based approach from Bosch. It aims to enable its automotive customers and itself to transform the way of developing braking systems by exploiting in-vehicle data continuously and remotely from start-of-design through calibration to validation. It is a generic approach not limited to braking systems only. It supports the validation of simulation models and therefore virtualized releases required for ambitious projects with less prototype vehicles. Carmakers gain benefits of shorter learning cycles and higher efficiency in the optimization and distribution of new software. Once the approach is successfully applied in the development phase, carmakers face the next big evolution step in exploiting in-vehicle data beyond series production has started. Field validation and exploration continues the connected braking systems approach in the field. Based on an edge computing architecture, an embedded data client access pre-defined internal component and system information that is typically not available on vehicle networks. Thereby, Bosch is following a smart instead of a big data approach and triggers data acquisition and preprocessing only after predefined events to limit busloads and data transmission volumes. Once the data is transmitted to the Bosch IoT (internet-of-things) cloud, a fully managed cloud service collects, processes and stores in-vehicle data. For analysis, data is queried using NoSQL or MongoDB database. Analytic results are visualized through dashboards and automatic reports. Bosch has established a strong partnership with its pilot customers using field validation and exploration for its braking systems in the field. Pre-defined braking system data of more than 10.000 vehicles is now continuously and almost in real-time sent to the Bosch IoT cloud. Based on the valuable field insights such as electrical, thermal and hydraulic loads, function activations or driver requests, Bosch and its customer are able to redefine specifications and to improve performance of braking systems. Field validation and exploration of in-vehicle data serves carmakers in a second step as a data source and key enabler for the development of new data based services such as predictive diagnostics, anomaly detection or even connected digital twins.
