Method/system for controlling a hybrid vehicle drivetrain

摘要

The present invention relates to method and a system in a vehicle comprising a drivetrain (1), comprising a drive unit, a transmission, and an electric machine. The method comprises the steps of receiving at least one signal from an accelerator control device, determining a requested torque of the drivetrain (1), determining (152, 252) an available torque of the electric machine (TISGav), determining (154, 253) an available torque of the drivetrain (1), at least partly based on the available torque of the electric machine (TISGav), and adjusting (110, 210) at least one gear shift schedule input parameters based on the requested torque and the available torque.
