Abstract: A tensioner for an accessory drive of an internal combustion engine has a belt on a first pulley connected to a drive shaft of the engine and a second pulley connected to an electric machine. The tensioner has a base configured to be fixed to a casing of the electric machine, a first ring rotating with respect to the base about a first axis, a second ring rotating with respect to the first ring about a second axis distinct from the first axis, a first tensioning pulley carried by the first ring and rotating with respect to it about its own axis, a second tensioning pulley carried by the second ring and rotating with respect to it about its own axis and elastic means acting on the first and on the second ring to push the first and the second pulleys into contact with respective spans of the belt.

Abstract: A control method of a hybrid powertrain for a vehicle having an internal combustion engine, an electrical machine connected to a crankshaft of the internal combustion engine via a transmission and a control unit are disclosed. The method includes acquisitioning first data representative of the efficiency of the internal combustion engine, of the electrical machine and of the transmission, acquisitioning second data representative of operating conditions of the vehicle, and processing the data, which includes calculating a distribution of the torque between the internal combustion engine and the electrical machine.
