Abstract | For several years, Argonne National Laboratory has taken a leading role in the benchmarking of various advanced hybrid vehicles for the US FreedomCAR industry-government partnership. Early designs provided highly desirable direct engine torque measurement (with telemetry for non-contact signal acquisition) for steady-state and transient operation in an operating Prius powertrain. Newer designs have done away with a sizable spacer and left the powertrain configuration intact. This was made possible by creating a new flywheel damper unit that inforporates the torque sensor, thus the powertrain fits back together without body modifications. Tradeoffs such as signal dynamic range and filtering are challenges that have been addressed by newer generation designs. |
