מדוע דרישות הבטיחות בתעשיית הרכב כה מחמירות?

Functional Safety, CMMI, Automotive SPICE – today’s automotive industry is protected by several guidelines and standards, but this wasn’t always the case.

In the past, safety standards were not as stringent, leading to numerous accidents and fatalities. For this reason, The ‘New Car Assessment Program’ (NCAP) was introduced. It’s an initiative managed by various national governments, including the US and EU, that informs consumers about the safety features of new cars and motivates manufacturers to enhance vehicle safety. That was the beginning of a global movement toward prioritizing vehicle safety, resulting in continuous advancements in automotive technology and stricter regulations to protect drivers, passengers, and pedestrians.

The automotive industry has come a long way since the early days of motor vehicles. Today, it stands as one of the most heavily regulated industries in the world, and for good reason. The safety of drivers and passengers is paramount, and the consequences of failing to meet safety standards can be dire. According to the World Health Organisation (WHO), road traffic accidents rank as the eighth most common cause of mortality worldwide. These staggering statistics underscore the critical responsibility that automotive manufacturers bear in ensuring their vehicles are designed and built to the highest safety standards.

Importance of safety in the automotive industry

The Automotive industry is under constant scrutiny to uphold stringent safety standards. This is not just a regulatory requirement but a moral obligation to protect lives. The consequences of neglecting safety can be catastrophic, leading to loss of life, severe injuries, and significant financial liabilities. Automotive manufacturers must adhere to rigorous safety standards to mitigate these risks. These standards are designed to ensure that every vehicle on the road is equipped with the necessary safety features to protect its occupants. From advanced electronic systems to robust structural designs, every aspect of a vehicle is scrutinised to meet these high standards. This comprehensive approach to safety is what helps reduce the number of motor vehicle accidents and save lives.

Why are automotive standards so strict and how did that happen? 

It won’t come as a surprise but the first automobiles were not safe to drive. While carriage-fitted combustion engines were patented by George B. Selden in 1879, it wasn’t until the early 1900s that the first safety measures were introduced with Connecticut enacting a speed limit under traffic law followed by New York penalising people for driving under the influence of alcohol in 1910. By the 1930s, tricolour traffic lights were introduced in the United States, most West European countries, and Japan.

The 1950’s was the decade when the installation of safety measures in cars lead to a dramatic change in the number of vehicles using public roads and of course, the number of accidents. The statistics were so concerning that in 1952, the first-ever working group, The UNECE World Forum for Harmonization of Vehicle Regulations (or WP.29), focused entirely on vehicle safety by discussing the formation of a safety standard. This resulted in the 1958’s agreement on a ‘unified approach to the approval of vehicles, components and parts in the European Union’. Finally, in 1959 the modern three-point seat belt was invented by Nils Bohlin and by the end of 60’s it was routinely installed in new cars in Europe.

Meanwhile in the US, a landmark non-fiction book, ‘Unsafe at Any Speed. Designed-In Dangers of the American Automobile’ written by Ralph Nader in 1965, criticised car manufactures reluctance to introduce safety measures and safety standards. The book was a bestseller in 1968 and can be at least partially credited with encouraging the National Traffic and Motor Vehicle Safety Act, to be passed. One of its regulations, launched in 1968, included establishing an agency that would enforce safety laws for every new car leaving the factory. This is how The National Highway Traffic Safety Administration was born. The new standard focused on ensuring that drivers are shielded against unreasonable risk resulting from the design and performance of vehicles.

As the 70’s, 80’s and 90’s all saw further surges in the number of cars produced and sold worldwide, there was a growing need for additional safety measures that would protect drivers as well as passengers. As the number of road accidents soared, these measures would have to be far stricter than the regulations introduced in the 50’s and 60’s. Functional safety standards, such as ISO 26262, were established to ensure the safe operation of electrical and electronic systems within road vehicles.

So, that’s how modern automotive standards as we know them today, were introduced.

What are the safety standards in automotive?

ASPICE (Automotive Software Performance Improvement and Capability Determination) 

ASPICE’s primary goal is to establish a framework that could be used in the process definition, implementation, and evaluation in software system development. It also helps assess the process maturity level necessary for developing software in the automotive sector.

CMMI 

While ISO 26262 and ASPICE are widely recognised in Europe, there’s also a framework that’s almost exclusively used in the US called CMMI (Capability Maturity Model Integration). This framework offers guidance for streamlining organisational processes and encouraging productive behaviours aimed at limiting the number of risks that can occur in service, product and software development. As is the case with two other standards, CMMI focuses on analysing systems and process workflows as a whole rather than in isolated segments. This approach ensures more efficient hazard detection and allows protective measures to be put in place. 

The CMMI was developed by the Carnegie Mellon’s Software Engineering Institute inשיתוף פעולה עם ארה"בממשלתי. Initially, the framework served as a tool for improving processes in organisations, חטיבותופרויקטים. 

How we approach the automotive standards at Spyrosoft 

At Spyrosoft, we work on a broad range of automotive projects that are completed within our עסקי רכב Unit. Regardless of whether we collaborate with an OEM/Tier 1 manufacturer or a small company developing innovative automotive products, our focus stays the same: ensuring that the projects, their processes and the final products are fail-proof and able to be certified under international automotive standards. 

As mentioned, these are notoriously strict, which also means that you need to follow them back-to-back on all levels of an automotive project. It can be challenging at times, but with support from our experienced functional safety engineers and quality specialists (with their הדרכות ISO 26262 ו-ASPICE), our clients successfully complete assessment and certification processes.
