摘要

#CMT# #/CMT# The method involves computing two time-dependent sequences of two parameters (Md1-soll, n-soll) characteristic for target rotational torque and target rotation speed, respectively based on target rotational speed parameter (n'-soll) or its change. A control loop is used for controlling the rotation speed and provided with a controller (2) that receives one of the time-dependent sequences. A torque signal (Md2-soll) is provided as controller output by the controller that controls an electric machine (6). The machine is mechanically coupled with an internal combustion engine (7). #CMT# : #/CMT# An independent claim is also included for a control device comprising a computation unit. #CMT#USE : #/CMT# Method for computation of time-dependent sequences of two parameters during rotation speed change in a motor car, an electric vehicle and a hybrid vehicle (all claimed). #CMT#ADVANTAGE : #/CMT# The method enables computation of the time-dependent sequence of the target rotation speed in a time-efficient and cost-effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of a control loop for controlling rotation speed as a part of an engine controller.
