Abstract: A system and a method for reducing a rotational imbalance of a drive train of a hybrid vehicle are provided. The drive train includes an internal-combustion engine, an electric machine, and a crankshaft. A reduction or nullification of the rotational imbalance takes place by actuating the electric machine. The actuation is implemented as an adaptive feed forward control, which provides an actuation signal for the electric machine. The actuation signal represents a desired torque to be generated by the electric machine, so that the electric machine outputs a torque that is at least approximately inverse with respect to the rotational imbalance to the crankshaft for the superimposition of the torque generated by the internal-combustion engine.

Abstract: An electric vehicle and a range extender engine are shown including the controls to operate the same.

Abstract: An apparatus and a method for pre-heating an engine of a mild hybrid vehicle are provided, and the apparatus includes: a pre-heating plug pre-heating the engine; a pre-heating controller recognizing the mild hybrid vehicle based on vehicle driving information, determining whether the mild hybrid vehicle enters a coasting driving mode based on the vehicle driving information, and generating a duty control signal according to a coasting driving time when the mild hybrid vehicle is driven in the coasting driving mode; and a driver supplying electrical energy of the low-voltage battery to the pre-heating plug according to the generated duty control signal.

Abstract: A compressor, an intercooler, and a fuel cell stack are housed in a housing compartment. The compressor and the intercooler are connected with each other by upstream side piping, and the intercooler and the fuel cell stack are connected with each other by downstream side piping. The upstream side piping is formed from upstream side first and second pipe parts, and the downstream side piping is formed from downstream side first and second pipe parts. Movement of the compressor and fuel cell stack relative to the intercooler at the time of a heavy collision of the vehicle causes disconnection of the upstream side first and second pipe parts and disconnection of the downstream side first and second pipe parts, to thereby cause communication of the upstream side piping and the downstream side piping with an internal space of the housing compartment.
