A Network Analysis Approach to Quantifying Changes in ADAS from Over-the-Air Updates

Abstract

Advanced driver assistance systems are changing the way that drivers interact with vehicles and may benefit from changes to consumer education that aim to improve the driver’s understanding of changes to their role. System updates will increasingly be applied over the air, which may lead to confusion about system capabilities if there is a substantial change, and there is a need to understand when changes need additional education. This paper uses a network analysis to quantify the change in driver assistance systems and also extends the approach to include a human user in the network. This paper describes the approach and presents an example comparing two adaptive cruise control systems, before and after an update. The network analysis quantified the connections within the network, with components of the driving assistance systems showing different connection strength with an increase in complexity of the system and with the addition of the user as a node in the network. The network analysis approach may be a useful tool for determining when additional consumer education is necessary for advanced driver assistance systems updates.
