Automotive Testing

Perform rapid, reliable, and cost-effective testing at every tier of the automotive tech stack, for every player in the automotive and autonomous vehicle value chain, and at every stage in the vehicle development lifecycle.

10BASE-T1S technology was developed as part of the IEEE 802.3cg-2019 standard to enhance in-vehicle Ethernet networks by providing Ethernet-to-the-edge connectivity, which is essential for zonal-based automotive architectures. It offers a cost-effective solution by utilizing a multidrop bus topology, allowing multiple devices to connect via a single unshielded twisted pair cable without the need for switches or gateways. This brief provides an overview of 10BASE-T1S technology, including related benefits, testing challenges and key testing considerations, along with setup and configuration guidelines to ensure optimal performance and reliability in both peer-to-peer and multidrop environments.

Spirent’s C-V2X Conformance Testing Solution Validated by DEKRA for Successful OmniAir Certification to help address the latest connected and autonomous vehicle challenges

GAC Motor develops and verifies their automotive Ethernet systems with Spirent test automation tools to deliver new in-car capabilities, because high-quality networks require high-quality testing. To guarantee flawless in-vehicle and V2X communication, compliance to standards developed by nonprofit organizations such as OPEN Alliance SIG and Avnu are required for building a complete ecosystem of interoperable devices. Read this case study to learn how Spirent assisted Hyundai design team in their efforts to determine the best Ethernet designs, to ensure their next-generation automobile conforms to IP and AVB standards.

Modern vehicles, whether autonomous or assisted, heavily rely on precise positioning, navigation, and timing (PNT) information for safety, efficiency, and mission-critical tasks. GNSS technology has evolved to meet these demands, offering a variety of hardware and services options, including multi-constellation and multi-frequency receivers, terrestrial and space-based augmentation systems, and complex array antennas. However, the inclusion of additional PNT sensors working together with GNSS has become increasingly important for seamless and reliable performance.

Italdesign has created a simulation platform to test connected and autonomous vehicle designs with hardware-in-the-loop. A Spirent GSS7000 signal simulator integrates with the platform to provide realistic, low-latency GNSS signals in real time to the receiver under test.
