How Do I Know if My Automated Test Equipment (ATE) Can Be Used for Functional Safety Testing?
IntroFunctional safety standards, such as ISO 26262, provide guidance on how to ensure safety is...
If you’re struggling to keep up with your current embedded software workload, LHP is strategically positioned to help you carry your projects from conception to completion with functional safety in mind. We have the experience to either complete the work for you, train your staff, or provide skilled professionals to join your team.
For embedded control engineers, safety standards must be followed in order to meet functional safety requirements. These requirements include management of the software development process, traceability, risk management, and quality assurance.
As the transportation industry continues to evolve toward autonomously-driven vehicles, functional safety of the intended hardware and software is the paramount concern of engineering organizations. The automotive standard ISO 26262, ASPICE, and others address the electrical components of the vehicle and define a safer way to mitigate risks and produce software in an environment where human lives are at stake.
Functional Safety in Legacy Controllers
In large organizations, the typical approach to product development is to use legacy code and product packaged into a new vehicle. With the emergence of autonomous vehicles, electric vehicles, and functional safety, that approach is no longer acceptable. Without completely redesigning every controller, organizations have to address the emerging standards and the evolution of vehicles from human control to machine control.
Functional Safety Intersection with Technology
With the emergence of non-traditional transportation means - urban air mobility, autonomous vehicles, platooning trucks, micro-mobility, etc. - the technology is pushing beyond what the safety standards can currently handle. For emerging technologies and new transportation means, aggregating safety standards across multiple industries into a custom solution can enable the commercialization of these new transport vehicles.
