método para controlar um sistema de trem motriz veicular e sistema para controlar um sistema de trem motriz veicular.

摘要

A control system/method for controlling engine (12) output torque in a vehicular powertrain system (10) including an electronically controlled engine and a torque load limited drivetrain system (11) is provided. The control will sense values of a control parameter (GR, OS) indicative of potential overloading of the drivetrain at maximum engine output torque and will cause engine output torque to be limited to a value less than the maximum value thereof.
