摘要

The worldwide convergence towards stricter fuel consumption and emission regulations is driving automotive engineers to offer new and optimised solutions to the challenges faced in all fields of vehicle design. In 2000, Ricardo and Valeo embarked on the build of a vehicle demonstrator, designated i-MoGen (Intelligent Motor Generator), to demonstrate the benefits of an integrated approach to the use of emerging automotive technologies in terms of: fuel economy, emissions, and vehicle driveability. The vehicle's main features are, amongst others, a downsized high output HSDI engine, a 42V, 6kW Flywheel Mounted Electrical Device (FMED) - acting as a starter motor, an alternator and a generator - a supervisory control system, a 42V HVAC system including PTC heater and an intelligent cooling system. The latter was defined in order to meet the thermal needs of the vehicle systems through an optimised architecture and a suitable level of flexibility. Vehicle systems thermal needs were identified during a testbed thermal survey where the influence of the vehicle's main thermal parameters on emissions and fuel consumption were assessed. The findings from the thermal survey were then used to provide detailed definition of the vehicle cooling system and the vehicle thermal strategy. The thermal strategy was defined and optimised, using simulation tools, in order to reduce overall power demand from the ancillaries and to operate the vehicle systems in their most efficient thermal window.
