Definitions
- the invention relates to a method for triggering a plurality of actuators of a safety system of a motor vehicle according to the preamble of claim 1.
- actuators such as airbags, but also belt tensioners, roll bars or pedestrian protection. Based on sensor signals in the control unit, the requirement for triggering and a desired triggering period is determined. Due to electrical impulses and energy supply, the actuators are triggered, the required amount of energy and time between the individual actuators may be different and across the large variety of actuators away in total with a simultaneous triggering all the available energy in the power source, such as an intermediate ignition capacitor exceeds.
- the object of the present invention is to specify such a method, which enables the most timely triggering of the individual actuators, without overloading the available energy source.
- a maximum group size of actuators for triggering within a time window is not rigidly predetermined, but adaptively adapted to the triggering situation.
- individual, at least partially different maximum group sizes are predetermined for successive time windows, and the maximum group size for the respective time window is adaptively determined on the basis of the actuators actually already triggered in previous time windows.
- a larger maximum group size results for the following time window than if, for example, all the maximum possible actuators had been triggered in the preceding time window.
- a sequence of maximum group sizes per time window is predetermined, for example, and the maximum group size valid for the respective time window is determined on the basis of the number of actuators actually already triggered in previous time windows.
- this is done by means of an index-controlled table in which the sequence of maximum group sizes is stored.
- the number of actuators already triggered in past time windows yields the index and the maximum group size is determined based on the table and the index.
- different triggering periods are at least partially predetermined for the individual actuators, and the maximum group size for the respective time window is determined adaptively on the basis of the actually already triggered actuators and their respective triggering periods.
- the sequence of maximum group sizes is changed as a function of the different triggering periods of the actuators triggered by the maximum group size for an actuator to be triggered with a triggering time duration exceeding one time slot in the sequence corresponding to this excess triggering time duration in the time windows following in the sequence each is reduced.
- the actuators are triggered according to their priority and the triggering of a number of actuators that exceeds the current, adaptively adjusted maximum group size is shifted to subsequent time windows.
- the sequence of maximum group sizes is stored in an index-controlled table and therefore a total of 14 actuators can be triggered at index value 0, only 13 at index value 1, etc.
- the concrete values are specified case-specifically and can also be used for several index values same maximum group sizes are provided, as here, for example, from the index value 8 for all subsequent index values also the maximum group size is always on 8 actuators.
- individual, at least partly different maximum group sizes are also deposited, in particular decreasing maximum group sizes just as the index increases.
- the realization of such an index-controlled table is case-specific in a corresponding memory of the control unit, that is, for example, for a particular vehicle series or at least their equipment firmly stored.
- the number of actuators already triggered in past time windows results in this embodiment, the index and is determined based on the table using the index, the maximum group size, at least provisionally. For the time being, deviations are conceivable from this fixed table, taking account of other aspects, for example because of actuators which have to be triggered for more than one time window or, for example, because of the possibility of recharging the energy source.
- the maximum group size for the respective time window is adaptively determined using the actuators actually already triggered in previous time windows by specifying a sequence of maximum group sizes per time window and those for the respective time window valid maximum group size is determined on the basis of the number of actuators actually already triggered in previous time windows.
- the maximum group size is determined from the index-controlled table for the specific time window on the basis of the index status.
- the sequence of maximum group sizes in the index-controlled table thus corresponds in this embodiment just the sequence of maximum group sizes for successive time windows only for exactly the case that exactly one actor would be triggered - in all other cases, it is due to the index level based on the actually already triggered actuators to a different sequence.
- FIG. 2 is intended to show an example of such a process in more detail. If the triggering of a first actuator is detected by the control unit by means of corresponding sensor signals, the index value 0 is at this point in time TO and the maximum group size, here for example 14, is derived on the basis of this index value 0 in the table according to FIG. If 3 actuators are to be triggered at this time TO, then this number is smaller than the maximum group size and all 3 actuators can actually be triggered, ie no factor for triggering must be reset in later time windows. Due to the triggering of 3 actuators, the index value increases in the following time window T1 to 3 and is therefore according to the table in Figure 1 for this time window T1, the maximum group size 11.
- the actuators preferably different priorities are given and are triggered within a time window, the actuators according to their priority, ie the first with the highest priority and are the triggering (en) of a current, adaptively adjusted maximum group size exceeding number of actuators in subsequent Time window moved.
- different actuators must be triggered together necessarily, such as on roll bars.
- Such interconnected actuators are then treated in accordance with the same mutually equal, if necessary, moved together in the subsequent time window.
- different triggering periods are predetermined for the individual actuators.
- the triggering duration is preferably predetermined in a defined number of those time windows in which the tripping takes place.
- the maximum group size for the respective time window is thereby preferably determined adaptively on the basis of the actually already triggered actuators and their respective triggering time duration, as will be explained in more detail in the exemplary embodiment according to FIG.
- the sequence of maximum group sizes is changed as a function of the different trigger periods of the actuators triggered by the maximum group size is reduced in each case with an actuator to be triggered with a tripping time periods exceeding a time window in the sequence corresponding to this excess trip duration in the time windows following in the sequence.
- an index-controlled table is preferably used in which the sequence of at least provisional maximum group sizes is stored and the number of actuators already triggered in past time windows yields the index and the provisional maximum group size is determined by means of the index using the table. additionally determines at least the number of actuators with the last time window exceeding the triggering time period and this number is subtracted from the provisional maximum group size and the adaptive maximum group size is determined.
- the term of the provisional maximum group size thus corresponds to the group size which would be available if deductions were not to be made for the current time window by triggering actuators with a longer trigger duration.
- the procedure in FIG. 3 again refers to the index table according to FIG. 1 and therefore results in an index value 0 and a maximum group size of 14 for the start time TO and a triggering of a total of 3 new actuators to be ignited.
- an actuator is referred to here as a "long-fuse” and is consequently set or increased in the line “active from the pre-interval" for corresponding subsequent time windows. If a "long-fuse" only requires an extension for exactly one subsequent time window, then the value is increased in exactly this one field, but even longer extensions can easily be taken into account by correspondingly adjusting the values accordingly for further subsequent time windows.
- a recharging of the power source at the maximum group size taken into account, preferably after a predetermined period of time, the index can be reset by one step.
- suitable means for carrying out a method are provided for triggering a plurality of actuators from an energy source, in particular a corresponding algorithm and storage means for storing the values, for example the index-controlled table, as well as the priorities of the different actuators , Any existing links between actuators and the characterization of certain actuators deposited as a long-fuse with their corresponding trigger duration and are processed accordingly during operation of the control unit.
