Simulation and HIL Testing for Rapid Development Hardware-in-the-loop (HIL) testing is a necessary tool for any automotive manufacturer or supplier in this era of software-defined vehicles. One reason for this is that, compared to the software in vehicles of even a generation or two ago, a modern vehicle presents challenges because of its software’s complexity, the quantity of its software, and the interconnected nature of its systems. The number of embedded controllers, and the quantity of the code installed on them, are both increasing every year. Powerplants of every kind, their power transmitting components, and sensors to monitor events inside and outside of the vehicle, are all connected to embedded controllers. Any time the software is updated on any of these, a new round of tests must be initiated.

What is the scope of SOTIF? An Acceptable Level of Safety The Safety Of The Intended Functionality (SOTIF) conveys a specific view on how automotive systems should be verified and validated as being functionally safe. It is not enough to just claim a system is safe. You must also:

What is SOTIF? (Safety of the Intended Functionality) ISO/PAS 21448 The practical operation of automated vehicles in a real-world environment requires that they achieve and maintain a certifiable functionally safe state. These vehicles must maintain this state even when they are operating in chaotic environments shared with older vehicles that may have less or no automation. Thus, attaining this certification—in an environment filled with variables—must itself encompass a broad spectrum of requirements and processes.

Improving driving safety through the reduction in opportunities for human error has been a focus of automotive manufacturers since the 1970s when anti-lock braking systems were first introduced. Automated features have since evolved to include more advanced technologies such as blind spot monitoring, adaptive cruise control, and self-parking. These features are now commonly known as advanced driver assistance systems (ADAS).
