Abstract
Abstract A method for controlling the rotational speed of a thermal engine residing in that a speed of rotation of the theraml engine is preset, a control signal based on this speed is shaped to control the speed of rotation of an electric motor according to the rotational speed of one of the input shafts of a differential mechanism kinematically linked with the electric motor and thermal engine fuel metering member is kinematically linked with an output shaft of the differential mechanism, and a correction signal is simultaneously shaped for the speed of rotation of the electric motor at transient operating conditions on the basis of the speed of rotation of the output shaft of the differential mechanism.

Claim 1
Independent Claim
144 words
A method for controlling the rotational speed of a thermal engine comprising the following steps: presetting the rotational speed of said thermal engine; shaping a control signal based on the rotational speed of said thermal engine to control a speed of rotation of an electric motor, said control signal being shaped according to a rotational speed of an input shaft of a differential mechanism kinematically linked with said electric motor and said thermal engine, said thermal engine having a fuel metering member kinematically linked with an output shaft of the differential mechanism; and simultaneously shaping a correction signal for the speed of rotation of the electric motor at transient operating conditions, said correction signal for said rotational speed of the electric motor at transient operating conditions being shaped on the basis of the speed of rotation of the output shaft of the differential mechanism.
Claim 2
Independent Claim
144 words
A method for controlling the rotational speed of a thermal engine comprising the following steps: presetting the rotational speed of said thermal engine; shaping a control signal based on the rotational speed of said thermal engine to control a speed of rotation of an electric motor, said control signal being shaped according to a rotational speed of an input shaft of a differential mechanism kinematically linked with said electric motor and said thermal engine, said thermal engine having a fuel metering member kinematically linked with an output shaft of the differential mechanism; and simultaneously shaping a correction signal for the speed of rotation of the electric motor at transient operating conditions, said correction signal for said rotational speed of the electric motor at transient operating conditions being shaped on the basis of the speed of rotation of the output shaft of the differential mechanism.
Claim 3
Dependent Claim
52 words
A method for controlling the rotational speed of a thermal engine as claimed in claim 1, wherein the correction signal for the speed of rotation of the electric motor at transient operating conditions is shaped to be proportional to the speed of rotation of the output shaft of the said differential mechanism.
