FIELD: engines and pumps.
SUBSTANCE: invention relates to vehicle engine start-up. Method of internal combustion engine starting in vehicle propulsion system, containing internal combustion engine, electric machine, gearbox and planetary gear, and comprises stages, at which setting vehicle into initial position by means of suitable gear and using brake indirectly acting on gearbox input shaft. Then controlling electric machine so, that planetary gear component is driven into rotation with negative rotation speed. As a result, internal combustion engine output shaft by means of planetary gear first component is driven with positive rotation speed so, that internal combustion engine can be started.
EFFECT: improved engine start-up.
