Functional Safety

Definition

Functional safety refers to the aspect of safety that ensures a system operates correctly in response to its inputs, preventing or controlling any malfunction that could result in harm. In the context of autonomous vehicles, functional safety encompasses various safety measures and standards designed to ensure that these vehicles can operate safely even in complex and unpredictable environments, thereby protecting passengers, pedestrians, and other road users.
