Water ingress into the Steer-by-Wire (SbW) electronics can cause short circuits and corrosion, thus resulting in unforeseen system malfunctions. Steering control units that are mounted on the front axle (road-wheel actuator) are exposed to harsh environmental influences. This vulnerability is particularly concerning when redundant sub-systems share the same enclosure, potentially leading to common cause failures. To mitigate this risk, monitoring water ingress in real time enables immediate actions such as smart degradation, timely maintenance, or the initiation of emergency stop protocols.

Detect water ingress in real-time to ensure safety integrity
How our sensors make a difference
Ensuring system safety integrity
Tight sealing is the main defense against water ingress in safety-critical enclosures. Utilizing sensors for real-time detection provides a cost-effective secondary safety measure against water ingress.
Enable smart degradation
Smart degradation economically adds a third layer of vehicle redundancy. Condition monitoring of safety-critical systems (such as SbW) is crucial for assessing the probability of a second failure and thus enhancing overall resilience.
Meet vehicle manufacturer requirements
With the surge in autonomous vehicles and impending regulations, OEMs must take on more liability. This emphasizes the necessity for real-time water ingress detection mechanisms to ensure system reliability and compliance.
