Driver assisted systems serve as the building blocks for autonomous vehicles and in this driverless car journey, L3 and L4 levels are expected to witness more growth over the short-term
It is an undisputed fact that the complex technologies and safety requirements addressing fully autonomous cars will mature over the long-term. As complexities increase, significant testing measures are required to ensure the safety of the system for the desired use case. At higher automation levels, vehicle safety would warrant tens of billions of miles in simulated environments. Simulated testing and virtual validation of autonomous electronic control units (ECUs) will be vital towards determining the levels of safety, and demand for simulation testing will increase going forward. Sharing his viewpoint with Auto Tech Review, Shaju S, General Manager and Head Automotive Business Unit at Tata Elxsi, said there also have been inter as well as intra-industry involvement through initiatives and strategic partnerships for quicker realisation and high volume deployment of safer and secure systems in the mobility landscape.
OEMs and Tier I suppliers are reconsidering the necessity and appropriateness of the current safety standards, further exploring the exposure, severity and controllability of the ECUs and vehicle in the outside world to better plan redundancies. Efforts are being undertaken to define safety goals, and requirements to accommodate autonomous vehicle technologies are being looked at, with the possibility of setting exceptions to certain standards, depending on the levels of autonomy implemented (semi and full autonomous). For fully autonomous vehicles, setting safety targets that suppliers can deliver and ones that fall in line with the road and transport regulations are evolving gradually.

The connected car technology and IoT platforms for the automotive space have exponentially increased the role of software and networking in vehicles. The sheer volume of software in vehicles is increasingly exposed and is vulnerable to malicious hacks from external parties. A fool-proof cyber security standard should be in place for data security. OEMs and Tier I suppliers are sparing no effort in defining a unified solution for the next generation cybersecurity standards, which will spawn new features.
Ensuring a secure ECU is a challenging task and there is a crying need to address these to build secure in-car and external connectivity solutions. Ensuring compliance with regulations such as ISO:26262 for functional safety, defining cybersecurity standards, threat detection, assessments and analysis processes will prove vital towards maturing security in the connected car ecosystem.
Safe driving autonomy solutions focus on incorporating the best of both worlds from humans, machines and the underlying technologies. Human individuality and data-based decision making are at the centre of this innovation. Accepting autonomous driving and connected car technology advancements is increasingly important for the auto industry and also for its intended consumers. Autonomous driving comes with its own benefits but also brings in challenges towards ensuring a safer driving user experience.
