LeanDRA by efs
At its core, LeanDRA provides a modular drive-by-wire kit that integrates seamlessly into existing vehicle architectures and established hardware and software stacks. The system offers a safe, deterministic interface between software functions and vehicle actuators, enabling precise and reliable control of longitudinal and lateral dynamics. This architecture allows engineering teams to develop, prototype, and validate automated driving functions efficiently under real-world conditions.
A key differentiator is the substantial reduction in total system cost. Compared to conventional drive-by-wire and test automation platforms, LeanDRA lowers hardware complexity, minimizes integration effort, and reduces operational overhead by up to 57%. Fewer additional control units, streamlined wiring, and a consolidated system architecture result in a leaner, more maintainable overall setup.
Time-to-operation is equally optimized. What traditionally requires weeks of setup, calibration, and validation can be operational within days. LeanDRA accelerates the transition from system integration to active testing by a factor of three, enabling faster iteration cycles and shorter development loops. This directly supports agile engineering workflows and rapid feature deployment.
Operational readiness is achieved in under one minute. LeanDRA boots, connects to relevant vehicle systems, and becomes fully functional in less than 60 seconds. This capability enables true development-concurrent testing, where validation can occur continuously alongside software development without lengthy initialization procedures.
Functionally, LeanDRA combines longitudinal and lateral control, high-accuracy path following, automated test triggering, and multi-layer safety mechanisms within a single unified platform. It delivers approximately twice the functional scope of conventional solutions by consolidating capabilities that would otherwise require multiple independent systems.
Beyond motion control, LeanDRA enables control of virtually all relevant vehicle systems and functions — from propulsion and braking to steering, lighting, and auxiliary systems. This holistic system access provides maximum flexibility for complex test scenarios, system validation, and advanced feature development.
With its scalable architecture, rapid deployment capability, and comprehensive control approach, LeanDRA establishes a cost-efficient, high-performance foundation for automated driving development, functional validation, and innovation testing in real-world environments.
