Introduction
Steer-by-Wire (SbW) is transforming the future of automotive control systems. By replacing traditional mechanical and hydraulic linkages with electronic controls, SbW systems offer improved precision, modularity, and opportunities for advanced driver assistance and automation. At Sigma, we support the full spectrum of development, from advisory roles to deep engineering, to help clients bring these innovations to market.
About the Client
The client is a global Tier 1 automotive supplier, preparing to launch a completely new product segment focused on Steer-by-Wire technology, with a target timeline between 2028 and 2030. They aim to deliver a comprehensive system solution, including both handwheel and roadwheel actuator subsystems, while ensuring readiness for series production. The challenge lies in coordinating development across hardware and software domains under tight constraints on innovation and time-to-market.
Solution
Sigma supports the project across three parallel development streams:
Demo Vehicle Development: Enabling functional demonstration and real-world validation of the Steer-by-Wire system.
Test & Simulation: Developing robust virtual and physical testing environments to accelerate system validation and reduce iteration cycles.
Serial Intent: Preparing the solution for series production through scalable system architecture and mature design processes.
Our In-House team provides comprehensive support through:
Technical leadership and R&D advisory
System architecture and software design
Development of embedded software components
Mechanical and mechatronic subsystem engineering
Results and Deliveries
By engaging across all three streams, Sigma has contributed to:
Aligned and coordinated actuator development for both hand wheel and road wheel systems
Streamlined collaboration between software, mechanical, and testing areas
Strengthened readiness for series production through early-stage system maturity and advisory input
A future-ready development approach supporting innovation without compromising quality or safety
