Functional Safety

Functional safety is part of system safety engineering and is concerned with helping to avoid the incorrect functioning of the complex and highly integrated electronic systems that are an essential part of modern vehicles.

Since the modern vehicle may contain over 100 microprocessors, around 1 GB of software code, and have over 85% of its functions influenced by software, functional safety is an essential part of the engineering processes for these vehicles.

Functional safety challenges include:

  • The adoption of the new international standard ISO 26262 Road vehicles – Functional Safety which has new concepts and new processes to take on board
  • The high level of electronics interaction and integration in vehicles, particularly in, but not limited to, hybrid and electric vehicles and integrated driver assistance systems
  • The adoption of new technologies such as electrical machines (motors) and energy storage systems (batteries) which have new potential failure modes to consider

MIRA is a leading independent provider of functional safety expertise and has over 100 years combined experience within its team. Many of the team have several years’ experience working with OEM and/or Tier 1 suppliers in a wide range of applications including powertrain, chassis, steering and braking systems, and more recently in hybrid and electric vehicles.

The experience available covers ISO 26262, IEC 61508, ISO 13849, ISO 15998, Def Stan 00-56 and the MISRA documents.

MIRA’s expertise is not limited to the automotive domain with recent projects including off-highway vehicles, defence applications and industrial control.
