ENGINE CONTROL METHOD, CONTROL SYSTEM AND VEHICLE Russian patent published in 2016 - IPC F02D45/00 

FIELD: machine building.

SUBSTANCE: invention relates to methods of transport vehicle control with ICE. Method and system for action at “change of the solution” situation during automatic engine shutdown equipped with two weight flywheel. Method and system are weaken or eliminate the risk of excessive resonance two weights at engine restart. Excessive resonance is reduced or eliminated by prohibiting restarting engine while its shaft rotation speed is in a predetermined interval of speeds, which includes area of rotations, at which the most probable occurrence of resonance. Other useful aspect of the invention consists in the fact that in the period when restart is prohibited, opening throttle valve is performed so that engine favourably is ready to restart as soon as the engine speed will drop and is below a predetermined interval of speeds. In the preferred version of the invention in the period when restarting prohibited, one or more additional loads applied to the engine are removed and thus engine at restart is allowed to fast acceleration and quick passage through a predetermined interval of speeds.

EFFECT: reducing or eliminating a risk of excessive resonance of two weights at engine restart.
