Definitions
- the invention relates to a method for controlling an auxiliary unit during starting or stopping an internal combustion engine on a body attached and coupled to the auxiliary unit. Furthermore, the present concerns Invention a control system designed to carry out this method.
- Integrated starter generators are in a so-called Stop-and-go operation is controlled in such a way that the internal combustion engine stop as soon as no mechanical power for locomotion Vehicle or the maintenance of auxiliary equipment is more necessary and that the internal combustion engine needs these services again start again. Because of the high performance of the starter generators the engine starts and stops very quickly, so that the driver has almost no delays in the response of his vehicle must accept. The problem, however, is that it starts or stops the internal combustion engine to vibrate the motor vehicle can be perceived by the vehicle occupants as unpleasant or annoying become. These disturbances mean acceptance of what is desirable per se Stop-and-go operations to a considerable extent.
- the object of the present invention was a device and to provide a method which is as trouble-free as possible Starting and / or stopping an internal combustion engine allowed.
- the method according to the invention is used to control one with an internal combustion engine coupled auxiliary unit while starting or stopping the Internal combustion engine attached to a body.
- auxiliary unit is basically any device separate from the drive train understand the power in the form of rotational energy to the internal combustion engine can transmit and / or take up from this.
- the auxiliary unit is an electric starter, an electric generator or a electrical integrated starter generator.
- the term internal combustion engine in the present case also the parts associated with vibration mechanics of the drive train.
- the regulatory process is characterized by that the auxiliary unit is controlled so that the excitation of resonant Natural vibrations of the internal combustion engine relative to the body is reduced.
- Such a control procedure can be used when starting or stopping a disturbing vibrations of the internal combustion engine Motor vehicle without design changes in the engine compartment to a minimum be reduced. What is important for this positive effect is the knowledge that vibrations primarily through the excitation of resonant natural vibrations of the Internal combustion engine are generated against the body and that the art or the sequence of the starting process or stopping process has an influence has to what extent excited resonant natural vibrations become. By actively regulating the auxiliary unit, which makes the generation more resonant Natural vibrations can be suppressed or minimized as far as possible the disturbing vibrations when starting or stopping the internal combustion engine be avoided.
- the auxiliary unit regulated such that during starting or stopping the internal combustion engine the dwell time in critical speed ranges, in which resonant natural vibrations of the internal combustion engine are minimized.
- Such a method must therefore only the speed of the internal combustion engine observed and the timing of starting or stopping in Dependence on this can be varied.
- the above critical speed ranges can e.g. B. in the frame can be determined from test series. These are preferably set so that they the natural vibration frequency of the internal combustion engine in its suspension correspond.
- the natural vibration frequency can be simulated and / or simple measurements for each type of motor vehicle and optionally individually easily determine for each individual motor vehicle, without this being an operation the internal combustion engine would be required. From the determined natural frequencies can then immediately read the associated critical speeds be, the speed in revolutions per second of the natural frequency in Numerical oscillations per second or both quantities are an integer Represent multiples of each other.
- the values for the critical speed ranges can be implemented immediately when implementing a control algorithm be used. Furthermore, these values can be customized for detected every motor vehicle and / or during the operation of a motor vehicle are constantly being redetermined and adapted.
- the dwell time can be critical Shorten speed ranges in particular by making the auxiliary unit short before and / or when passing through the critical speed ranges an increased Power is supplied.
- the auxiliary unit then transmits this increased power on the internal combustion engine, which accelerates their speed change and thus the desired rapid passage through the critical speeds. Since the Power increase is only temporary, this will result in the energy supply of the auxiliary unit is not overloaded.
- the invention further relates to a control system for controlling one with a Internal combustion engine coupled auxiliary unit, the internal combustion engine is attached to a body.
- the control system is designed to to carry out a method of the type explained above. That is, according to the process, in particular the auxiliary unit, can be regulated in this way, that an excitation of resonant natural vibrations of the internal combustion engine compared to the body is reduced.
- the control system preferably has signal inputs for the speed and / or the rotational position of the internal combustion engine.
- the rotational position the internal combustion engine is typically in degrees of the crankshaft angle measured.
- the control system can be adjusted from the rotational position by a time derivative of the speed of the internal combustion engine or a corresponding one Determine size. Knowing the speed allows the auxiliary unit to do so to regulate that the dwell time in critical speed ranges is minimized.
- the control system can in particular be designed to increased the auxiliary unit during starting in critical speed ranges Perform performance or critical during stopping Speed ranges from the auxiliary unit to derive increased power.
- the auxiliary unit can basically be any separate device act the rotational energy with the internal combustion engine in one or two Can exchange directions.
- the auxiliary unit can be an electrical one Starter (“starter”), an electrical generator or - particularly preferred - be an integrated starter generator, the latter depending on the electrical circuit Absorbs energy and generates mechanical rotational energy from it (Starter) or vice versa absorbs mechanical rotational energy and from it generates electrical energy (generator).
- Starter electrical one Starter
- an electrical generator or - particularly preferred - be an integrated starter generator, the latter depending on the electrical circuit Absorbs energy and generates mechanical rotational energy from it (Starter) or vice versa absorbs mechanical rotational energy and from it generates electrical energy (generator).
- starter generators are especially for a low-consumption and low-emission stop-and-go operation Internal combustion engine used with frequent stops and restarts.
- the single figure shows the components of a motor vehicle with an inventive regulated integrated starter generator.
- the figure shows schematically the internal combustion engine 2 of a motor vehicle and an integrated starter generator coupled to the shaft of the internal combustion engine 3 shown.
- the internal combustion engine 2 and the integrated starter generator 3 are about indicated suspension points 1 and over a support rod 4 is mounted on body structures 5.
- the internal combustion engine 2 and the drive train (clutch, gearbox, etc.) coupled to it can be in swing these suspensions. This can lead to resonant natural vibrations come in which the internal combustion engine 2 with its horizontal and / or vertical natural frequency oscillates with respect to the vehicle structure 5. Such resonant natural vibrations are disturbing in the vehicle Vibrations noticeable.
- the starter generator 3 can be used both as an electric motor and be used as a generator.
- the Acceptance of this for reasons of fuel economy and emission reduction desirable stop-and-go operation by the user does not depend, however
- Control system 6 reached Reduction is particularly important the excitation of natural vibrations in suspensions that drive the drivetrain support in the vertical direction.
- the figure first shows one with the integrated starter generator 3 coupled control 7, which the starter generator 3 supplied or checked electrical power.
- the regulatory system 6, which for example in a microcontroller or within the usual Motor control can be implemented as a program is on the output side with the Control 7 coupled, the system of control 7 commands u can send the electrical to be replaced with the starter generator 3 Prescribe performance.
- the control 6 also receives signals on the input side from known motor sensors, which represent the engine speed n and / or the absolute crankshaft angle ⁇ . With the help of these input signals, the control 6 can determine whether the internal combustion engine 2 during a starting process or during the Stopping in a critical speed range in which the speed with at least one vertical or horizontal natural frequency of the internal combustion engine and the drive train essentially coincides. In these speed ranges there is excitation of resonant natural vibrations of the internal combustion engine and thus to the undesirable vibrations in the motor vehicle.
- the control 6 is designed so that the dwell time of the internal combustion engine in the critical speed ranges to minimize.
- the controller 6 controls the control 7 so that during the engine starting or stopping the acceleration or delay before the phase in which the engine speed is increased matches the resonance frequencies of the engine mount. hereby reduces the drive train to build up vibration energy in the time available for the resonance frequencies and thus the transmission of vibration energy on the vehicle body. In this way, the Increased comfort of vehicle occupants during starting or switching off and thus the acceptance of stop-and-go operations can be improved.
