| 摘要 |
The invention concerns a method applicable to a motor vehicle parallel hybrid drive train, comprising a heat engine, at least one electrical machine, a variable speed ratio transmission member, a first clutch linking the heat engine to the electrical machine, and a second clutch linking the transmission member to the electrical machine or to the heat engine. The method includes the following successive steps which consist in: a) placing the first clutch in open position; b) after positioning the second clutch in slip control, powering the electrical machine so as to drive same with kinetic energy higher than the energy required for starting the heat engine; and c) closing the first clutch so as to transmit, from the electrical machine to the heat engine, an energy at least sufficient to compensate the resisting torque of the heat engine shaft, and drive same at a starting speed. |
