Vehicle electrification

With our comprehensive capability, technical focus and optimised processes, Ricardo will continue to take a lead in the development of passenger cars with electrified powertrains.

Engineering the organisation

With the exception of BEVs, increasing electrification brings increasing complexity in packaging of the new electrified systems alongside a future version of today’s combustion engine, which will itself be more complex. In addition to this, a further challenge is that the high level control systems that then must be calibrated to enable these electrified architectures to deliver a seamless and fully blended experience for the customer. To help deliver this, we are implementing an approach to electrified vehicle development that we are calling R-Intelect (Integrated Electrification). This combines a focus upon functional system engineering, together with the application of an integrated model-based development (IMBD) toolset.

The individual functions of a vehicle powertrain, such as acceleration and braking, are delivered by a combination of sub-system behaviours and for an electrified powertrain many more sub-systems are involved. The product development discipline that exists to optimize the combination of sub-systems for overall powertrain or vehicle delivery of a given function, is functional system engineering. Within our development organisation the functional system engineering provides an additional layer over and above the traditional organizational delineations of engine, transmission, chassis and other sub-systems engineering teams.

Ricardo IMBD Toolset

Our IMBD toolset providing a framework for the exchange of data and information between analysis and simulation operations with a hierarchy of tools that can be applied through the development V-cycle. As each new product programme is initiated, an experienced cross-business team is used to define the optimum modelling approach for each step of the process. Crucially, the IMBD environment enables the use and continual updating of sub system modelling outputs in higher level system models, and for this data to be replaced by test results as they become available later in the development cycle.
