SDV Telemetry Project - On Hold

Vehicles are undergoing an incredible period of transformation with many different aspects of vehicles changing at the same time. The rapid growth of electrification of vehicles is simplifying the vehicle design and promoting a transition to new E/E architectures. Moving away from the old approach of discrete ECU’s doing individual functions, ECU’s are also consolidating into domains and sharing compute resources, reducing vehicle cost. Driver experiences are expanding, including radical improvements in driver assistance and driving automation, improved entertainment, as well vehicle personalization. Software innovation underpins every aspect of these many areas of evolution and vehicle software is becoming more advanced and complex as vehicles shift towards becoming Software-Defined Vehicles (or SDV).
Vehicles are also becoming more connected, with services and capabilities connected to, and benefiting from, the cloud. This flow of data improves the user experience and enables a wider array of innovations. The Connected Vehicle Systems Alliance (COVESA) is an important industry initiative that is working to bring standards to connected vehicles and promote the rapid development of these technologies. Sonatus is a member of COVESA and has adopted the Vehicle Signal Specification (VSS). To help explain the importance of VSS, it may be useful to give some context about Sonatus.
At Sonatus, we’re accelerating vehicle software innovation by delivering key software building blocks that enable OEMs to shift to software-defined vehicles faster and at lower costs. These building blocks allow OEMs to continually improve and enhance their vehicles at any time, even after they are sold. Sonatus offers a range of products and solutions to speed vehicle manufacturers' journey towards SDV in areas like data collection, vehicle automation, vehicle networking, cybersecurity and others.
SDV brings many valuable benefits to vehicle OEMs, suppliers, and customers:
But to realize these benefits, OEMs need to enable application development both within the OEM and from the vehicle ecosystem. Most of these applications rely on access to quality, fine-grained data from vehicles and ability to add new features, but today sharing that data has challenges:
Two of Sonatus’s solutions aim to address these first two key challenges and enable faster vehicle innovation: Vehicle Data Collection (VDC) and Vehicle Automation Manager (VAM).
Sonatus Vehicle Data Collector enables vehicle manufacturers to create fine-grained, customized collection policies that give them the precise data they need and under specific trigger conditions. Through customized fine-grained data collection, OEMs can achieve an array of valuable use cases like predictive maintenance, diagnostics, product planning, cost optimization, and much more. VDC’s solution operates in the vehicle as well as in the cloud.
Sonatus Vehicle Automation Manager builds on our data collection capabilities but also adds actions. Through VAM, OEMs can create new features and experiences at any point in the vehicle’s life or automate the testing of existing functions by simply defining workflows using lightweight, yet flexible policies. VAM enables developers to draw upon data from across the car, and take actions in many vehicle systems, all without coding and difficult validation.
But the third challenge of inconsistent signal naming can remain a barrier. Sonatus VDC & VAM leverage VSS from COVESA to overcome this: VSS defines a common data model for vehicle signals, sensors, actuators, and attributes. This common framework is critical both in the vehicle and in the cloud. VSS offers multiple benefits to different layers of the value chain:
For Sonatus, we have had a positive experience with VSS and see the scalability and reuse benefits it provides. We are excited to be one of the leaders in helping bring this technology to market and hope, through our advocacy, we can help demonstrate the benefits of the wider adoption of VSS across the industry.
