Estimating the term…
A method for controlling the start-up phase of a motor vehicle driven by an internal combustion engine (12) wherein the internal combustion engines (12) is started by an electrical machine (16) that can be operated as a motor, a preferably automatically atuatable clutch (50) being located in the drive train (11) between the internal combustion engine (12) and the electrical machine (16). A faster start-up response can be achieved if the internal combustion engine (12) is driven by the electrical machine (16) when the clutch (50) is engaged during start-up, and if the clutch capacitance (MK) is reduced according to a defined parameter, preferably the engine speed, the time or the torque (ME) of the electrical machine (16) or similar.
A method for controlling the start-up phase of motor vehicles which are driven by an internal combustion engine and comprise an automatically actuated clutch, with the internal combustion engine being accelerated at first by a starter from standstill, with an engagement process of the clutch being startable from a predetermined threshold speed in order to initiate a start-up phase and with an injection process being started at a time after a synchronization time, wherein the time of a start of the engagement process of the clutch lies before the synchronization time, and the end of the engagement process of the clutch lies after the synchronization time, and wherein the clutch is open at a beginning of the start-up process.
A method for controlling the start-up phase of motor vehicles which are driven by an internal combustion engine and comprise an automatically actuated clutch, with the internal combustion engine being accelerated at first by a starter from standstill, with an engagement process of the clutch being startable from a predetermined threshold speed in order to initiate a start-up phase and with an injection process being started at a time after a synchronization time, wherein the time of a start of the engagement process of the clutch lies before the synchronization time, and the end of the engagement process of the clutch lies after the synchronization time, wherein the clutch is closed at the beginning of the start-up phase, and a transmission of the motor vehicle is in a idling position, whereupon the clutch is opened at a first point in time, whereupon a gear is engaged at a second point in time, whereupon the engagement process of the clutch is started at a third point in time and whereupon the injection process is started at a point in time after the synchronization time.
An apparatus for controlling a start-up phase of a motor vehicle which is equipped with an internal combustion engine and an automatic clutch, with the apparatus being arranged to trigger a starter in order to accelerate the internal combustion engine from the standstill and to start the engagement process of the clutch at a predetermined engine speed in order to initiate a start-up phase and to start an injection process at a time after a synchronization time, wherein the apparatus determines the start of the engagement time of the clutch prior to the synchronization time, and an end of the engagement process is determined after the synchronization time, wherein it keeps the clutch open initially.
