摘要： The invention concerns an infinitely variable transmission with power by-pass comprising at least a planetary gear set (8), a reduction stage (4; 10, 11) and two electric machines (3; 3a, b), the various elements constituting said transmission being distributed on two parallel power paths connecting the heat engine (1) of a vehicle to the two wheels (2) thereof. The invention is characterised in that the first path comprises two electric machines mounted in series, and the second path assembles the other transmission elements, and said transmission comprises at least a second reduction stage (5, 13, 14), separate from the first.

摘要： The invention concerns a device for estimating a vehicle load. The invention also concerns an automatic transmission vehicle using such a device. The inventive estimating device establishes a first signal representing a static component (C_static) of the vehicle load using a circuit (3) which receives an information representing the engine torque (Engine_torque). A second signal representing a dynamic component (C_dynamic) of the vehicle load using a circuit (7) which receives an information concerning the instantaneous transmission ratio of a circuit (1) and an information of the vehicle speed. The two components (C_static and C_dynamic) are subtracted from each other by a circuit (5).
