The research on this theme aims to develop a modular software and hardware environment to support virtual vehicle prototyping, where performance characteristics and the ergonomic interfaces between the vehicle and its occupants can be evaluated at an early stage in the design cycle. Underpinned by research into perception in a virtual environment and the development of standards to maximise task-specific simulator functionality, the corresponding validity of the simulator platform to support benchmarking and evaluation will be assessed in a three-staged work programme: foundation, specific evaluation test-ases and implications for future simulator design. By linking simulation applications at the University of Leeds and Computer Aided Engineering (CAE) in JLR in two specific test-cases, the capability for coherent and modular driving simulation design to support efficient and cost-effective vehicle technology benchmarking will be assessed. Such assessments will include HMI, Package and Vehicle Dynamics, each underpinned by robust evaluations of simulator validity in each test-case.
