Many Advanced Driver Assistant Systems functionalities were introduced to boost vehicle safety, efficiency and comfort. Implementing these functionalities such that all the functional and temporal requirements are satisfied is challenging. This thesis is concerned with the temporal requirements. More precisely, it aims to identify and implement a methodology to estimate the end-to-end latency distribution of various signals paths in ADAS, with the aim of verifying the compliance of latency requirements. The methodology is validated by testing it on a hardware set-up that mimics the behaviour of an existing adaptive cruise control system at TNO. This system is equipped with two different communication buses and multiple ECU's with different temporal behaviours. A simulation-based method is used to address the problem. The simulation models of the individual components were first made and then combined to make the model of the complete system. The simulation model uses the input-output latency of the individual components, without any interference from other components, from the hardware model and computes the complex interactions between and within the components. The results of the experiments performed on both simulation and hardware models conform that a simulation-based method could be used to determine end-to-end latency in a distributed automotive systems.
