Development and testing

Our test cells provide thorough analysis of novel hybrid components, offering a unique range of virtual tools to help clients minimize development expenditure and reduce the time to vehicle launch.

These robust solutions can be applied to all parts of automotive systems:

  • Powertrain and driveline performance
  • Hybrid and electric vehicle transmissions
  • Thermal management optimization
  • System simulation
  • Structural robustness analysis

Ricardo’s capabilities

  • E-machine testing - includes characterisation, functionality and durability to validate systems for production
  • In-The-Loop facilities allow testing of embedded control systems in a virtual environment
  • High voltage batteries can be tested at cell, module and pack level
  • Equipment for full vehicle testing includes a 4WD chassis dynamometer, linked to a high voltage battery simulator to prove out the functionality, performance, and durability of hybrid and electric vehicles
  • Analysis of HW resource usage.
  • SiL, MiL and HiL testing.
  • Functional and vehicle integration testing.
  • Robust testing and validation processes using DFMEA, integrated with DVP&R, leading to PPAP (Production Release).
  • Bespoke precision test rigs at component and vehicle level.
  • Extensive testing and validation processes including in-house EMC and NVH capability.
  • Systems integration testing

Design and simulation

To support H&EV architecture definition, Ricardo extensively uses validated modelling and simulation tools.

Defining vehicle system architectures presents significant challenges:

  • Capturing top level requirements with the right level of detail can be difficult
  • Electrical architectures are becoming increasingly complex
  • The need to introduce new technology and feature content demands the acquisition of new knowledge
  • Features are increasingly defined by software content
  • The number of suppliers with a vested interest in each sub-system is increasing

A 3-phase approach is typically used to define robust architectures definition and associated development programmes.

  • Ricardo has proven processes and tools that are used to progress from architecture definition through configuration selection to control strategy development
  • Ricardo developed V-SIM, a powerful simulation tool made of "plug & play" vehicle parametric models enabling: 
    • Accurate fuel consumption / (EV) autonomy prediction
    • Complete and flexible virtual environment simulation
    • Timing and development costs optimisation
    • Co-simulation tailored to the subject being addressed
