FIELD: transport engineering. ^ SUBSTANCE: group of invention relates to automobile with power plant and method of its control. With automobile moving backwards in direction opposite to expected directed direction of movement according to current setting of position of gearshift mechanism SP, correcting torque Ta is set corresponding to measured road gradient theta. Torque Ta is set as required torque to bring speed of automobile with one driver moving backwards, i.e. in direction of rolling downwards, to preset speed level of automobile. Then set correcting torque Ta is compared with torque Tc providing slow movement which is set within tolerable range of output torque Tc. Larger of said torques is taken as torque Tm from electric motor. Group of inventions provide effective control of speed of automobile moving backwards in direction opposite to expected direction of movement, with bringing it to preliminarily set speed level of automobile. ^ EFFECT: improved safety. ^ 15 cl, 4 dwg |
