Document Type and Number:

WIPO Patent Application WO/2012/091858

Kind Code:

A3

Abstract:

A mobile machine (10) includes a propulsion system (12). The propulsion system may include a prime mover (14), a traction device (16), and a clutch (CI) operable to transmit power produced by the prime mover to the traction device. The propulsion system may also include propulsion-system controls (19) operable to control the clutch. The propulsion- system controls may include at least one information processor (44) configured to estimate a temperature of the clutch based at least in part on an estimated slippage (SLCl) of the clutch and a fluid temperature (OIL1).
