Based on further ingenuity, it is possible to support a heavy and large electric motor on an engine body with sufficient strength while driving the electric motor with a belt without slipping, thereby providing a more streamlined industrial hybrid engine. The industrial hybrid engine is provided with an endless rotation band wound around a drive pulley of a crankshaft and a motor pulley of an electric motor for motive power. The electric motor is attached to an engine case in a position-fixed state using one support bracket. The support bracket includes first and second support portions for attaching the electric motor, and attachment portions positioned between the first and second support portions for attaching the electric motor to the engine case.

The invention relates to a torque transmission device (1), having torque input means (2, 24) intended to be rotationally coupled to a crankshaft of an internal combustion engine (7), and torque output means (8) intended to be rotationally coupled to an input shaft (10) of a gearbox (36) and to a rotor (34) of an electric machine, the torque input means (2, 24) being capable of pivoting with respect to the torque output means (8) around an axis (X).

A vehicle includes an engine, electric machine, starter-generator, and a controller. The engine and electric machine are each configured to propel the vehicle. The starter-generator is coupled to the engine and is configured to adjust engine speed during an engine start-up event. The controller is programmed to, in response to engine speed increasing towards a target speed during an engine start-up event, generate a target drag torque with the starter-generator to reduce overshoot of the target engine speed.
