Imagine you are driving a car into something. Then there must be functions that protect you as an occupant from injury. For example, the airbag must be triggered in certain situations.
Or you want to charge your electric car. To do this, drive to the charging station and plug the plug into the car. Then it must not happen that you get an electric shock when you touch your car or the charging plug. In the background, appropriate functions are needed to make the process, and therefore the car, functionally safe.
As a team, we take on the task of analyzing which risks exist for the various functions and formulate safety objectives and how these can be implemented. We look at the individual parts from many different perspectives and the formulated requirements are of course also tested at the end.
It starts with the components with software and hardware development, then the individual components are considered at a system level, then the components together with other components and then at some point in interaction in the entire car. It’s hard to imagine, but the individual functions are very extensive in themselves. In the overall context of the vehicle, however, they appear very small.
