Method for controlling a DCT transmission with energy recovery

Abstract

The invention relates to a method for controlling a DCT transmission of a motor vehicle comprising a powertrain (1) including an internal combustion engine (3), a starter-generator (7) rotationally linked with the internal combustion engine, and a DCT transmission device (4) including an electric machine (5), a gearbox (41, 42) having a primary shaft (6), a coupling clutch (K0) between the internal combustion engine and the primary shaft 6, and a gear train (65) kinematically linking the primary shaft to an input of the electric machine. In this method, with the hybrid motor vehicle decelerating and the electric machine (5) in generator mode, the method comprises the following steps: If the rotational speed of the primary shaft (6) is less than the idle speed of the internal combustion engine (3), the coupling clutch (K0) is opened, allowing the internal combustion engine (3) to continue running, driving the starter-generator.
