Problem
The transition to fully autonomous vehicles requires a new approach to safety-critical systems, as conventional fail-safe systems are inadequate when there is no human driver to take over in case of a fault. Current steering and braking systems often rely on mechanical linkages and redundancy concepts designed for human-driven vehicles, which do not meet the stringent safety demands of SAE Level 4 and 5 autonomy. Regulations are emerging that will prohibit in-lane stops in the event of system failure, necessitating systems that can maintain operation despite faults.
Solution
Chassis Autonomy develops fail-operational steer-by-wire and brake-by-wire systems designed specifically for autonomous vehicles, ensuring continued functionality even in the event of a single point failure. Their CS1 steer-by-wire system employs a duplex architecture with dual controllers, an array of sensors, and twin sub-actuators to maintain directional control, exceeding ASIL-D requirements. This ground-up design eliminates traditional rack and pinion concepts, providing a redundant actuation system that allows the vehicle to continue operating normally despite system or vehicle faults.
Target Audience
The primary target audience includes autonomous vehicle developers and manufacturers of SAE Level 4 and 5 vehicles, particularly those focused on safety and regulatory compliance.
