Enabling autonomous
mobility through actuation

Defining the new state-of-the-art for automotive fail-operational actuation systems 

The world’s first fail-operational steering system

Our products

Steer-by-wire

Chassis Autonomy’s current focus is on the development of a class-leading steer-by-wire system for autonomous vehicles. The system is a ground-up design that is fault tolerant and fail-operational, meaning that autonomous vehicles fitted with the system can continue to steer, even in the event of a system fault. This provides the safety and reliability that is necessary for the wider adoption of autonomous mobility.

Brake-by-wire

To enable true autonomous mobility, we recognise that we need to solve the other critical gap and that is fail-operational braking. Our current focus is upon steer-by-wire however, as we continue to scale up the company, we will begin to place more resources on the development of our brake-by-wire system.

The technology

Our ground-up designed steer-by-wire system is fault-tolerant and fail-operational, exceeding the requirements for ASIL-D and ISO 26262.

Autonomous vehicle focused

Our ground-breaking CS1 steering actuator is designed specifically for use in autonomously driven vehicles, eliminating conventional rack-and-pinion technology as a steering wheel is no longer required.

Ground-up design

Our CS1 steering actuator is designed from the ground-up and employs a unique mechanical, electrical and software architecture to set the new state-of-the-art.

Safety is paramount

In a world where autonomous vehicles operate without a human driver, our systems ensure safety for vehicle occupants and other road users.

Fail-operational

Our systems ensure that the  autonomous vehicle maintains steering functionality even in the event of a single point fault or failure.

Our story

Chassis Autonomy was founded by Peter Johansson and Thomas Li in October 2021 after a project developing steer- and brake-by-wire systems was cancelled by the automotive OEM they worked for. When the opportunity arose, they span-off the complete development to create Chassis Autonomy with a vision to apply their extensive automotive industry experience and develop the products towards serial production.


The company is committed to continuing the development of by-wire actuation systems that will enable the next step change in the automotive industry – the unrestricted deployment of fully autonomous vehicles.
