Definitions
- the invention relates to a method and a device to control the drive unit of a motor vehicle according to the preambles of the independent claims.
- DE-A 195 36 038 describes a method and a device to control the drive unit of a motor vehicle known, in which a torque of the drive unit is dependent controlled by a setpoint for this torque becomes.
- a torque of the drive unit is dependent controlled by a setpoint for this torque becomes.
- a maximum permissible torque Drive unit formed, this with an actual Drive unit torque compared and fault response measures initiated when the actual torque the drive unit exceeds the maximum permissible torque.
- the maximum permissible torque depends on the target torque value educated. This in turn is based on the Position of a control element that can be actuated by the driver, for example of an accelerator pedal, or depending on that of others Control systems or functions predetermined target torque, for example depending on a target torque an engine drag torque control and / or an idle speed control calculated.
- the maximum allowable torque becomes dependent on the target torque value using a characteristic curve or a map is formed.
- a consideration of Tolerances of the drive unit, which e.g. through internal friction is not described. This is also permissible Moment depending on the driver's desired torque, so that at a theoretically conceivable error in the calculation of this Moments the permissible torque is also incorrect.
- Torque base Monitoring a control of a drive unit Torque base is significantly improved because the Formation of the maximum permissible torque, which of the monitoring underlying, tolerances are taken into account, too when external intervention works.
- driver's desired torque is not in the calculation of the permissible torque is received.
- FIG. 1 is a control device for a multi-cylinder Internal combustion engine 10 shown.
- the control device comprises an electronic control unit 12, which consists of at least a microcomputer 14, an input 16 and one Output unit 18 exists.
- Input unit 16, output unit 18 and the at least one microcomputer 14 are via one Communication bus 20 for mutual data exchange with one another connected.
- the input unit 16 are the input lines 22, 24, 28 and 30 fed.
- the line 22 comes a measuring device 32 for detecting the pedal position, the line 24 from a measuring device 34 for detection the engine speed, the line 28 from a measuring device 38 for detecting a motor load representative Size and line 30 of at least one other Control device 40, for example a control device for traction control for transmission control, for engine drag torque control, for driving speed control, etc.
- the quantity representing the engine load are air mass, air flow meter depending on the embodiment or pressure sensors to record the intake manifold pressure intended.
- the Control unit other sizes essential for engine control like engine temperature, driving speed, the time after Start, intake air temperature, etc.
- An output line 42 is connected to the output unit 18, on an electrically operated throttle valve 44, which is arranged in the air intake system 46 of the internal combustion engine is leads.
- the under the described by programs of the microcomputer realized engine control takes place through coordination the filling intervention (air intervention), the ignition angle setting and the change in fuel metering (Blanking of individual cylinders, displacement of the air / fuel composition) based on the torque the drive unit.
- the filling intervention air intervention
- the ignition angle setting and the change in fuel metering (Blanking of individual cylinders, displacement of the air / fuel composition) based on the torque the drive unit.
- a target torque Control of the drive unit selected This target torque is converted into a setpoint for the filling to be set, in an ignition angle and / or a fuel metering correction converted. In this way, the torque of the drive unit approximates the specified target torque.
- the maximum permissible torque When determining the maximum permissible torque, how shown below using the flow diagram according to FIG. 2, based on accelerator pedal position and engine speed from at least one map in which the essential Tolerances are taken into account, the maximum permissible Moment read. Furthermore, in a preferred embodiment another map is provided, which according to Start of the drive unit, especially when the drive unit is cold increased tolerances, for example as a result of Friction considered. This maximum allowable moment in Post-start also depends on the accelerator pedal position and Engine speed determined according to another map. This map is switched to if after Start certain conditions exist, for example the Temperature of the engine, the intake air temperature and / or the elapsed time after the start within specified value ranges lie.
- the maximum allowable moment determined in this way becomes for the above-mentioned torque monitoring and / or for limitation of the target torque.
- the maximum allowable The moment depends on the driver's request. Are functions active, which replace the driver's request or the torque versus that increases or decreases the driver's request maximum permissible moment, which in the above-mentioned way is formed, the actual situation of the controller not again. This is particularly important for interventions, which is the moment of the drive unit versus the driver's request increase, such as in a cruise control or an engine drag torque control.
- reliable torque monitoring (and / or limitation) too ensure is provided based on the driver's request formed maximum permissible moment with that of the to compare external interventions with the target torque.
- the larger of the two values is considered permissible Moment of monitoring and / or limitation supplied.
- an additional offset value is formed, that from a map depending on the resulting permissible torque and the engine speed is formed. This Offset value takes into account depending on the operating state different tolerance and leads to change in the resulting maximum permissible moments and therefore to be taken into account that depend on the operating condition of the engine Tolerance.
- the torque setpoints formed by external interventions such as engine drag torque control (mimsr) or a vehicle speed control (mifgr) and the moment of the drive unit compared to the driver's request a maximum value selection 100 fed.
- the target torque value for the external interventions is then in a maximum value selection 102 with that depending on the driver's request formed maximum permissible torque compared.
- the each larger of the two moment values is the resultant maximum permissible torque with torque monitoring fed.
- the maximum permissible depending on the driver's wishes Moment is either in a first map 104 or in determines a second map 106, depending on which operating state is present.
- the accelerator pedal position becomes the two maps wped and the engine speed nmot supplied.
- the maximum permissible torque is above the two maps stored these two input values, the map values be applied.
- the post-start phase which by the solid position of the switching element 108 is represented, the one read from the map 104 maximum permissible torque value during the post-start phase the maximum permissible value read from the map 106 to the maximum value selection 102.
- the switching element 108 becomes dependent on the condition for the post-start B_next start switched.
- the post-start phase is preferred Embodiment before when a certain time the engine temperature has not expired since the start indicates a cold drive unit and / or the intake air temperature is in a certain range of values.
- the resultant determined in the maximum value selection 102 maximum permissible moment is in a link 110 mizul corrected to the maximum permissible moment.
- the latter is fed to a comparator 112.
- An actual torque miist is supplied, which depends on input variables in 114 like the actual filling depending on the measured air mass rl, the engine speed nmot, the current ignition angle and Engine fueling setting is formed becomes.
- the actual torque miist is compared with that in the comparator 112 maximum permissible moment mizul compared.
- Exceeds it the maximum permissible torque is particularly by switching off the fuel supply a safety reaction (SKA) triggered. The fuel supply remains switched off until until the actual torque falls below the maximum permissible torque falls.
- SKA safety reaction
- the resulting point becomes maximum in the junction 110 admissible torque corrected with a torque offset value mioff.
- a map 116 this is dependent on the engine speed and the resulting maximum allowable moment, the initial value of the maximum value selection 102.
- the Map values are also applied.
- the map 116 shows the tolerance values (e.g. due to friction generated tolerances, component tolerances, etc.) filed depend on the operating state of the drive unit.
- There one Input variable of the map 116 even with external interventions represents the maximum permissible torque these tolerance values are also taken into account when external Interventions work.
- the offset value the tolerances is not dependent on the accelerator pedal position formed so that the torque monitoring even during the Intervention of external functions is guaranteed. Further goes the target torque is not in the formation of the maximum allowable Moments so that theoretically occurring errors in the The calculation of the target torque should not be included in the monitoring.
- the input variable for the map 116 is not the maximum permissible torque that is called a measure of the torque request considered, but the filling request derived therefrom, i.e. the maximum permissible to be set via the throttle valve Should fill. Monitoring then becomes the basis of Fill values carried out. With this in mind, use the term moment also the filling as a monitoring variable to understand.
