Abstract
A transmission for a hydraulic hybrid motor vehicle includes a planetary gear train () capable of differential operation. The planetary gear train has a first element () linked to an internal combustion engine (), a second element () linked to drive wheels () of the vehicle, and a third element () linked to a hydraulic pump (). The transmission () further includes a hydraulic machine which drives the drive wheels () by way of a link between the third element () of the planetary gear train () and the hydraulic pump (). This link includes a speed reducer () that provides, when the whole of the planetary gear train is rotating at the same speed, a reduction in the speed of rotation of the pump relative to that of the internal combustion engine () that is greater than a value of approximately two.
