Power-split continuously variable transmissions
(CVTs) represent a promising technology to improve the fuel economy of high-power off-road vehicles such as construction and agricultural machines.
There are capable of keeping the combustion engine running within the optimal range in terms of
fuel economy and performance. Power-split CVTs
are a very specific type of CVT because this kind
of transmissions are characterized by the combination of a traditional mechanical transmission and a
continuously-variable transmission. A CVT powersplit design for high-power vehicles combines the
advantages of pure hydrostatic drives at low speeds
with the high efficiency of power split drives at
higher speeds.
In this paper, a general control-oriented modeling
approach based on Takagi-Sugeno (T-S) fuzzy models for the design of fuzzy observers for sensor-fault
detection in power-split continuously CVTs is developed. It has been shown by simulation studies
and experimental results that this approach can be
used to reconstruct a selection of measurable values
such as the hydrostatic pressure under varying load
conditions and switched transmission modes. |
