Abstract
Modern vehicle powertrains include electronically controlled mechanical, electrical and hydraulic systems, such as double clutch transmissions (DCT), powerful regenerative braking systems and distributed e-Machines (EM), which leads to new safety challenges. Functional failure analysis of events such as the sudden failure of a DCT or EM, and the development and the validation of suitable controllers and networks, can now be evaluated using co-simulation techniques, from the early stages of product development. A co-simulation toolchain with a 3D vehicle and road model, coupled with a 1D powertrain model, is used to enable the definition of hardware and software functions, and also to support the rating of the Automotive Safety Integrity Level (ASIL) during hazard analysis and risk assessment in the context of ISO 26262. This innovative approach may be applied to a wide range of powertrain topologies, including conventional, hybrid electric and fully electric, for cars, motorcycles, light or heavy duty truck or bus applications.
