| 摘要 |
The invention concerns a gear changing device (10) for a motor vehicle mainly powered by a heat engine comprising, from upstream towards downstream, a main heat engine (12), an auxiliary electric machine (30) directly linked in rotation to the engine and connected at least to a storage battery (31), a coupling member (14) mobile between a declutched state and a clutched state, and a transmission (16) for setting up at least two transmission ratios (N, N+1) to drive the vehicle wheels (20) in rotation. The invention is characterised in that, when there is a gear change during which the transmission (16) shifts from a current transmission ratio (N) to a higher ratio (N+1) and during which the coupling member (14) is declutched, electronic means (24) control the electric machine (30) to adjust the torque so as to slow down the main heat engine (12). |
