FIELD: transportation.
SUBSTANCE: invention relates to vehicle acceleration. Method of accelerating vehicle with propulsion system including engine, gear box, electric machine, planetary gear and locking device, wherein method is started when vehicle is actuated for forward motion, and locking device is in disengagement position. In method a) controlling electric machine so, that to deliver torque corresponding to product, on one side, of propulsion system torque, required for acceleration, and on other side, gear ratio of planetary gear. Simultaneously with stage a) measuring first gearbox input shaft speed and controlling engine, to change its rotation speed, approaching it to first rotation speed. Then transferring locking device into locking position, when first component rotation speed is equal to said first rotation speed.
EFFECT: improved vehicle driving.
