Engineering the Next Generation of Steer-by-Wire Technology

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.

Sigma Technology 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

By engaging across all three streams, Sigma Technology 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
