ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a system for considering different amounts of components for determining at least one control quantity.
BACKGROUND OF THE INVENTION
Such systems are, for example, known in adaptive transmission controls. Adaptive transmission controls are, for example, known from U.S. Pat. No. 5,157,609 and German patent publication 4,136,613 as well as the article of Welter et al in the publication “AT, Automobiltechnische Zeitschrift” 94 (1992) 9, starting at page 428 and the article of Welter et al in the publication “AT, Automobiltechnische Zeitschrift” 95 (1993) 9, starting at page 420.
In automatic transmissions, the gear ratio changes are determined, in general, in dependence upon the vehicle longitudinal speed and the engine load (throttle flap angle). This takes place utilizing a characteristic field. In adaptive transmission systems, the characteristic field (with which the transmission ratio changes are determined) can be adapted to the behavior of the driver (driver type), to the traffic situation and/or to the driving situation to which the vehicle is subjected. When assessing the behavior of the driver, it is generally evaluated as to whether the driver is interested more in a driving power orientated driving style or in a driving style optimized for consumption. With the evaluation of the traffic or driving situation, one can, for example, differentiate whether the vehicle is in city traffic, forward of or in a curve, traveling uphill or is in overrun operation. The particular characteristic line is selected in dependence upon the evaluation of the above-mentioned points from a number of different characteristic lines. Furthermore, a shift of the basic shift characteristic field can be provided.
In the state of the art, it is suggested to arrive from different algorithms (for example, startup evaluation, gradient evaluation) at different types of assessment of the particular driver type present. These assessments are collected and then processed to an instantaneously valid type of driver, for example, by maximum formation, weighted sum formation and/or moving-window sum formation. The above-mentioned different types of assessments can be prioritized differently in this processing.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a system for considering different amounts of components to determine at least one control quantity which can be adapted as simply as possible and without great complexity to different requirements.
The system of the invention is for considering different amounts of components (setcomponent
i
) for forming at least one control quantity (Bg) such as for controlling the operation of a motor vehicle. The system includes: at least two different supply objects (LO
i
) for forming respective components (setcomponent
i
) for determining a control quantity (Bg); at least one collector (Sa) to which the components (setcomponent
i
) are supplied and the collector (Sa) functioning to form the control quantity (Bg) in dependence upon the supplied components (setcomponent
i
); and, caller/administrator means (Ar, Vw) for controlling the feeding of the components (setcomponent
i
) of the supply objects (Lo
i
) to the collector (Sa).
The invention proceeds from a system for considering different amounts of components for determining at least one control quantity such as for steering the operation of a motor vehicle. Such a system is known from the state of the art mentioned above. In this prior art, a value is determined as the control quantity for adaptive transmission control. This value characterizes the type of driver or the driving style. Here, at least two different supply objects are provided such as startup evaluation, gradient evaluation. With these supply objects, a component is determined in each case for determining the control quantity. The determined components are then supplied to at least one collector which forms the evaluation quantity, for example, by maximum formation, weighted sum formation and/or moving-window sum formation of the individually determined components.
The essence of the invention is that means are provided by means of which the supply of the components of the supply objects to the collector is controlled. With the system of the invention, it is possible, in a simple manner, to adapt the number of components to the particular situation. These amounts are to be considered in the formation of the evaluation quantity.
In an advantageous embodiment of the invention, the caller/administrator means are so configured that the determination of the components is started by driving the individual supply objects and/or that the components, which are determined by the supply objects, are supplied to the collector.
Furthermore, it is provided that the caller/administrator means contains data as to whether individual supply objects are active or can be activated. The caller/administrator means can then be subdivided into a caller part and an administrator part. The administrator part contains data as to whether individual supply objects are active or can be activated.
If the caller/administrator means are subdivided into a caller part and an administrator part, then, as a reaction to driving the individual supply objects by the caller part, an enable must take place via the administrator part to supply the components of the individual supply objects to the collector.
A further advantageous configuration of the invention proceeds again from a subdivision of the caller/administrator means into a caller part and an administrator part. Here, it is provided that the caller part initializes the collector by means of an initialization signal and/or the caller part calls up the result, which is formed in the collector, and applies this result to form the control quantity. The formation of the control quantity can take place as follows: via a mean value formation, via a maximum formation and/or by a weighted and/or moving-window sum formation of the determined components.
In an especially advantageous embodiment, the system is used in the context of an adaptive transmission control in a motor vehicle. In this system, means are provided as the supply objects (Lo
i
) which determine the components (setcomponent
i
) in different ways, the components (setcomponent
i
) representing the instantaneous type and/or driving style of the driver of the motor vehicle; the control quantity (Bg), which is formed in the collector (Sa), represents the instantaneous type and/or style of the driver of the motor vehicle; and, function elements of the transmission are driven in dependence upon the formed control quantity (Bg).
