What is R-OAM?R-OAM is a flexible analysis tool that uses automated event detection to create objective measures of vehicle attributes from test or simulation data. It offers reduced development efforts fitting with increasingly reduced project timeframes.R-OAM is a modular system based around a core software module that can support a variety of toolboxes aligned to specific activities.Low costAffordable and significantly lower pricing over similar systems.FastIntelligent automated analysis of data acquired from either vehicle testing or simulation software reduces overall development time.FlexibleR-OAM has a flexible, modular structure allowing additional toolbox extensions to the core software for future expansion and customisation.Experience-basedDeveloped from over 25 years of vehicle attribute development and characterisation.

R-OAM client benefitsReduced development costUsing recorded CAN data minimises acquisition set-up time, and automated event detection dramatically reduces analysis time and cost. Value added dataR-OAM reduces attribute development process steps allowing the engineer to focus on the improvement of driver experience.Increased consumer satisfactionR-OAM enables improved subjective performance through real objective data comparison with target data.
