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
- 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
