Definitions
- the present invention relates to a method for preparing an acceleration operation of an internal combustion engine.
- the acceleration behavior is an essential part of the driving experience and is an important aspect for potential buyers. tiger factor for a purchase decision.
- a delayed response and a non-optimal acceleration behavior are contrary to this sporty driving behavior. For example, after a construction site or a speed-limited area on a highway, a driver can perform a spontaneous acceleration operation to quickly return to a high speed. In overhull operations on rural roads, it is of great importance that the motor vehicle has an optimal acceleration behavior to complete the Sprinthohlvorgang as quickly as possible.
- the overtaking is unnecessarily prolonged, which can pose a major security risk, both for the occupants of the overtaking motor vehicle and the overtaking vehicle and any oncoming traffic represents.
- ADVANTAGES OF THE INVENTION By detecting a first event indicative of an imminent acceleration event, the engine and other parts involved in the acceleration operation, such as turbocharger and / or transmission, can be prepared in time for the acceleration process and necessary actions can be initiated become.
- a first variable influencing a drive torque on the at least one wheel is changed in such a way to the first event indicating the acceleration process that an optimal acceleration behavior is achieved.
- variable influencing the drive torque on the at least one wheel size all the adjustable sizes of the motor vehicle, which influence the drive torque to the wheels and thus ultimately the speed of the motor vehicle, can be selected.
- the variables can act on all components of the motor vehicle, for example on the internal combustion engine, the transmission, the turbocharger, a clutch, an electric generator or a drive train.
- the first variable can be set early to values that allow an optimal acceleration behavior.
- the first size is expediently changed only to the extent that structural protection conditions permit, for example a catalyst temperature, a turbine temperature of the turbocharger, a maximum charge pressure.
- a second variable influencing a drive torque on the at least one wheel is first of all changed in order to counteract the change in the first variable.
- the drive torque to the wheels of the motor vehicle is thus initially kept approximately constant as long as the acceleration process is not yet triggered.
- Size of the internal combustion engine and the other involved in the acceleration process components of the motor vehicle are prepared for the acceleration process. By changing the second size is ensured that the current speed of the motor vehicle or the instantaneous drive torque is initially maintained on the wheels of the motor vehicle.
- the second variable is changed in such a way that the change in the second size in the course of the first event is at least partially reversed.
- the change of the first size is now effective and it is immediately the optimal acceleration behavior of the motor vehicle available.
- a delayed response is avoided in a simple manner, without expensive components or large cost. Since expediently the first and the second variable are changed shortly before the acceleration process, the internal combustion engine and the remaining components of the motor vehicle are operated only for a short time with the changed values of the first and second variables.
- the inventive method is particularly suitable for use in an internal combustion engine in combination with a turbocharger, a compressor and / or an automatic transmission or semi-automatic transmission.
- the method according to the invention should not be limited to this specific embodiment, but is suitable for any type of motor vehicle.
- an engaged gear is changed to the first and / or second event and a suitable gear is engaged.
- This is particularly suitable for motor vehicles with automatic transmission or semi-automatic transmission. For example, after the first event, first in a lower gear and after the second event in a higher gear.
- the automatic switching process during an acceleration process can thus be optimized.
- one or more engine variables are changed as the first variable.
- a cylinder filling in particular the cylinder filling with air, is increased to a value which is greater than a normal value for the normal operation of the internal combustion engine.
- a target value of the cylinder charge may be determined as a difference to this normal value or as an absolute value.
- the cylinder filling for example, by changes in a camshaft phasing, a camshaft stroke adjustment, closing times of Valves and / or valves are influenced in an intake pipe and / or in an exhaust pipe.
- a turbocharger speed, an exhaust gas mass flow, an exhaust gas enthalpy, a pressure ratio across a throttle valve of the internal combustion engine, and / or the position of a control flap of the compressor can be changed as a first variable.
- the exhaust gas mass flow can be changed, for example, by means of an exhaust gas recirculation valve with a valve flap. This ensures, in particular, that the boost pressure of the turbocharger is brought to an optimum value.
- the boost pressure may be further varied, for example, by a pressure ratio across a turbine of the turbocharger or by an exhaust gas temperature.
- the first size is changed depending on one or more factors.
- the factors may include, for example, external conditions and current thermodynamic parameters such as an ambient pressure, an ambient temperature, an intake air temperature and / or a component protection temperature, in particular an intake air temperature, the catalyst temperature and / or the turbine temperature of the turbocharger.
- the factors can also relate to the instantaneous, current driving behavior of the motor vehicle in order to ensure the optimal acceleration behavior starting from the current movement of the motor vehicle.
- Acceleration and / or a maximum turbocharger speed can be considered as factors.
- the factors can also be specified by the driver.
- the driver may set values manually, such as a maximum value, a minimum value, or the setpoint value of engine sizes.
- the on position can be done for example via an on-board computer or a special actuator.
- the driver may also specify a driving mode, eg, a normal, sport or fuel economy mode.
- a firing angle and / or the position of the throttle valve are changed as a second size.
- the ignition angle is retarded.
- an injection of individual cylinders can be prevented and the internal combustion engine can only be operated in a partial engine operation.
- variables of other components of the motor vehicle can be changed as a second size.
- the coupling can be at least partially opened.
- an electric machine can be operated as a generator. Power generated by the electric machine can be temporarily stored.
- a first actuating element is actuated as a first event, for example by the driver.
- the first actuating element can be designed, for example, as a switch, a lever, a knob or another MMI element in the dashboard area or on the steering wheel. If the driver knows that he wants to accelerate in a short time, for example shortly before the end of a speed limit, before the end of a construction site or before an overhaul, he operates the first actuator. The motor vehicle prepares automatically for the upcoming acceleration process.
- a delayed response is thus avoided and ensures a sporty driving.
- the operation of a special actuator thereby achieving a better acceleration performance, increases driving pleasure and gives the driver a sporty driving feel.
- the overtaking process is unnecessarily prolonged.
- the driver is already at the beginning of the overtaking process the best possible acceleration of the motor vehicle available and overtaking can be completed as quickly as possible.
- the first event can also be detected automatically by the motor vehicle.
- the road can be monitored automatically by means of a video surveillance system which recognizes traffic signs.
- the detection of a sign indicating an imminent acceleration process such as the detection of a particular traffic sign, eg the end of the speed limit, the end of the construction site, the end of the overbending prohibition, constitutes the first event.
- the driver can select, for example, which size or sizes of the components of the motor vehicle should be changed as the first size.
- a multi-stage preparation of the acceleration process is made possible. If the driver selects a first stage, the values of the first and second variables are changed, for example, but the same gear remains engaged or the driver can switch to another gear himself. If the driver selects a second stage, the optimum gear is additionally selected and inserted automatically.
- the first actuating element can be designed in particular as a toggle switch with two flip-flops or as two different switches or buttons. It is also conceivable that the driver selects the first stage by operating the first actuating element once and by operating the first actuating element twice within a short time interval, e.g. within half or one second, the second stage selects.
- the change in the position of the accelerator pedal forms the second event.
- the achievement of a kickdown position or a maximum stop of the accelerator pedal may form the second event.
- the changes of the first and second sizes are reversed if the second event does not occur within a predetermined time interval after the first event. This ensures that the internal combustion engine and the remaining components of the motor vehicle are not set over a longer period of time with unfavorable, not optimally adjusted Operate sizes, if ultimately no acceleration process takes place. It is advisable to store the values of the first and second size before they are changed after the first event.
- the predetermined time interval may include, for example, one, five or ten seconds. Thus, a delayed response is avoided without unnecessarily increasing fuel consumption.
- An arithmetic unit according to the invention e.g. a control unit of a motor vehicle, is, in particular programmatically, configured to perform a method according to the invention.
- Suitable data carriers for providing the computer program are, in particular, floppy disks, hard disks, flash memories, EEPROMs, CD-ROMs, DVDs and the like. It is also possible to download a program via computer networks (Internet, intranet, etc.). Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

- the cylinder 3 is provided with a combustion chamber 4, to which via valves 5, an intake pipe 6 and an exhaust pipe 7 are connected.
- the intake pipe 6 is connected to the exhaust pipe 7 via an exhaust gas recirculation valve 13 with a valve flap 13a as an actuator for external exhaust gas recirculation.
- the valve flap 13a can be controlled by a signal (EGR) from a control unit (ECU) 16.
- EGR exhaust gas recirculation valve
- ECU control unit
- an injection valve 8 that can be controlled with a signal T 1 and a spark plug 9 that can be activated with a signal ZW are connected to the combustion chamber 4.
- the internal combustion engine 1 according to FIG. 1 is based on the spark ignition method. It should be understood, however, that the invention is not dependent on the method of ignition of the internal combustion engine and is well suited for self-ignition internal combustion engines.
- a boost pressure sensor 18 which outputs a signal LD indicating the boost pressure in the intake manifold, and a throttle valve 12 whose rotational position is adjustable by means of a signal DK housed.
- the intake pipe 6 is further provided with an air mass sensor 10 and the exhaust pipe 7 with a lambda sensor 1 1.
- the air mass sensor 10 measures the air mass of the fresh air supplied to the intake pipe 6 and generates in dependence thereon from a signal LM.
- the lambda sensor 1 1 measures the oxygen content of the exhaust gas in the exhaust pipe 7 and generates a signal lambda ( ⁇ ) in dependence thereon.
- the lambda probe 1 1 is an exhaust system (not shown) including a catalyst, for example. 3-way catalyst, followed by.
- the compressor 19 of a turbocharger is arranged in this example in internal combustion engines with turbocharging.
- the compressor 19, in particular a control flap of the compressor 19, can be controlled by means of a signal KP.
- the turbine 20 of the turbocharger is installed in internal combustion engines with turbocharging after the lambda probe 1 1, the turbine 20 of the turbocharger is installed.
- the turbine 20, in particular a rotational speed of the turbine 20, can be controlled by means of a signal TR.
- controller 16 is connected to an accelerator pedal sensor which generates a signal FP indicative of the position of a driver-operable accelerator pedal 17 and thus the engine torque requested by the driver.
- actuator 15 is present.
- the actuator 15 is formed in this example as a driver operable button in a dashboard of the motor vehicle. Upon actuation of the button 15, a signal TB is transmitted to the control unit 16.
- the controller 16 is adapted to perform a preferred embodiment of a method according to the invention, which is shown in Figure 2 as a block diagram to perform.
- a motor vehicle is operated in a normal mode.
- the current values of variables of the components of the motor vehicle such as engine sizes or sizes of the turbocharger, thereby represent normal values.
- the motor vehicle moves at approximately constant speed, ie an approximately constant drive torque on the at least one wheel and performs no significant acceleration processes.
- a first event indicative of an acceleration event is registered.
- the driver operates the button 15.
- the driver is, for example, on a country road and would like to overtake a moving in front of him motor vehicle. The driver recognizes that in the near future no counter traffic will occur and an over-hollowing process is possible and actuates the button 15.
- step 103 the control unit 16 first stores the current values of a first and second magnitude influencing the drive torque on the at least one wheel.
- a target value of a cylinder fill forms the first size.
- the controller 16 increases the desired value to a value that allows an increase in the engine torque and ultimately the drive torque to the at least one wheel.
- the control unit 16 calculates the correspondingly changed setpoint value as a function of an intake air temperature, an ambient temperature, an ambient pressure and a driving mode set by the driver.
- control unit 16 changes a firing angle as the second variable and, for example, performs a retardation. Furthermore, the control unit 16 changes a position of the throttle valve 12 as a second quantity and, if necessary, inhibits an injection of individual cylinders 3 of the internal combustion engine 1, which leads to a reduction of the engine torque and ultimately of the drive torque to the at least one wheel.
- the increase and decrease of the drive torque on the at least one wheel counteract each other, so that the output from the engine 1 to a drive shaft engine torque and thus the drive torque to the at least one wheel remains substantially the same.
- the changes of the first and the second size are signaled to the driver, for example as an HMI element (human-machine).
- HMI element human-machine
- step 104 the control unit 16 checks whether, within a time interval of, for example, five seconds, a second event triggering the acceleration takes place.
- a time interval of, for example, five seconds a change in the position of the accelerator pedal 17 in the sense that the driver gives more throttle represents the second event. If there is no change in the position of the accelerator pedal 17 within the time interval or the position changes such that the driver uses less gas If the driver gives and / or presses the brake, this means that the driver does not want to carry out an acceleration process.
- the controller 16 reverses the first and second size changes in step 105 and restores the first and second sizes to the values stored at the beginning of step 103. The aforementioned signaling would be canceled.
- step 106 the controller 16 reverses the second size change that occurred in step 103.
- the engine torque of the internal combustion engine is increased due to the changed first size, correspondingly increases the drive torque on at least one wheel and the motor vehicle undergoes an optimal acceleration process.
- step 107 Once the acceleration process is completed in step 107 and the speed of the motor vehicle no longer increases, the motor vehicle is operated again in the normal mode and the method returns to step 101, indicated by reference numeral 108th
