Functional safety forms an integral part of overall system safety and is primarily concerned with the avoidance of hazardous effects associated with malfunctioning behaviour of complex and highly integrated electrical/electronic control systems.
Since the modern vehicle may contain over 100 microprocessors, around 100 million lines of software code, have over 85% of its functions influenced by software and 40% of the entire vehicle architecture comprising of electrical/electronic components, functional safety is an essential part of vehicle engineering.
State-of-the-art practices for automotive functional safety require that design, verification and validation activities are embedded into product development processes, typically integrated into a classic automotive “V” model. Functional safety is therefore intended to be “designed in” to complex vehicle electrical/electronic control systems as they are developed to ensure overall product safety.
In modern times, many challenges exist for functional safety, including:
- The ever-increasing levels of vehicle features and functions controlled by electrical/electronic systems
- The highly distributed nature of these electrical/electronic systems
- The electrification of vehicles and the adoption of new technologies such as advanced electrical machines and energy storage systems
- The growing demand for Advanced Driver Assistance Systems (ADAS)
- The drive for autonomous and connected vehicles
- The threat of the cyber criminal
At HORIBA MIRA, functional safety forms part of a wider engineering discipline known as Vehicle Resilience (VRES) which ensures that current and future electrical/electronic vehicle content will be safe, secure and functional as technological advancements are realised.
