ABSTRACT:
BACKGROUND AND SUMMARY OF THE INVENTION
This application claims the priority of German patent document 199 07 795.9, filed Feb. 24, 1999, the disclosure of which is expressly incorporated by reference herein.
The present invention relates to a process and apparatus for assisting the driver of a motor vehicle in operating components of the motor vehicle.
In recent years, the amount of the equipment in vehicles has increased substantially. As a result, the collective operation of the individual components takes place by a continuously increasing number of operating elements, for which printed operating instructions have conventionally been provided. Furthermore, an effort has also been made to design the operating elements in such a manner that the respective operating conditions or functions which are to be switched by each is easily recognizable. This applies, for example, to the electric seat adjustment, in which it is known to provide a switch configured in the form of a small seat, including switch elements shaped like a seat surface, a backrest and a headrest. By operation of one of the elements, the associated seat part is adjusted correspondingly. A similar situation exists for sliding roofs.
For other operating elements, it is, for example, known to the applicant to provide a display with different operating elements arranged at its edges. The operation which is to be switched by means of these operating elements can be changed, with the actually switchable operation shown on the display.
In German Patent Document DE 44 10 985 A1, an operating mode is provided for one or more operating elements, in which information can be emitted concerning the respective operating elements, either by display on a video screen or as acoustic information. In this operating mode, triggering of the particular function which is switched by means of the operating element can be suppressed. On the other hand, it is also possible to trigger this function in addition to the displayed or acoustically emitted information; advantageously this occurs when it is recognized that a hand approaches the operating element. Information can be displayed or indicated in this manner which relates directly to the operating element, and/or which relates to conditions which can be switched subsequently.
It is an object of the present invention to improve the assistance provided to the user in devices such as described above.
This and other objects and advantages are achieved by the method and apparatus according to the invention, which includes an “assistance request element”. After actuation of the assistance request element, information is then emitted concerning the operating condition or function which can be switched (in normal operation) by means of the operating element which is operated immediately thereafter.
This arrangement is especially advantageous when the user wants to request information concerning a particular operating element. That is, after operation of the assistance request element, information is emitted concerning only the next actuated operating element; thereafter subsequent operations of the operating elements can switch the corresponding functions once again. Thus, the operation is advantageously simplified. The user can request the information and, immediately after he has found the correct operating element for the desired function to be switched based on the displayed or emitted information, he can switch the function by another operation of this operating element.
In addition, it is advantageous to design the system such that misunderstandings cannot occur during its operation. That is, when, by means of a switch, a system is switched into the mode in which only a display or emission of an information of the switchable functions takes place (function query mode), misunderstandings might occur when a user, after actuating an operating element, expects the corresponding function to be switched, because he is familiar with the system and does not pay attention to a display of information. The user may then think that a malfunction is occurring.
According to the invention, however, actuation of an operating element after the operation of the assistance request element does not switch the respective operating condition (as occurs in normal operation); rather only an information is emitted concerning this operating condition which can be switched in the normal operation. As a result, the user is advantageously enabled to become familiar with the individual functions gradually, without switching the respective operating condition. In particular, this can avoid the switching of actually undesired operating conditions which could otherwise result from a searching trial of the operating elements. In addition to a gradual learning, it is also possible during the setting of operating conditions of one component, to request, in an up-to-date manner, the switchable operating conditions of individual operating elements.
The operating elements may be manually actuatable, or they may also consist of voice decoders. In the latter case, at least individual components are operated in a voice-controlled manner. By speaking corresponding keywords, the individual operating conditions of the components are selected.
The assistance request element itself may also be operable manually, such as a key or button, or it may also consist, for example, of a voice decoder, which may be activated when the word “HELP” or the word “ASSISTANCE” is recognized.
The components which are operable in this manner may be, for example, the air conditioner, seat adjustment, a navigation system, an audio and/or video set, a cruise control system, the vehicle lights or other vehicle components. Also, information concerning the system may be shown on a display.
Advantageously, a display can be provided which is, for example, in the driver's field of view. The switchable operating conditions can then easily be perceived by the driver of the vehicle.
In another embodiment of the invention, information is emitted by means of a voice emission. As a result, the driver's attention can better remain focused on the traffic. In addition, the information can be perceived in a simple manner by all vehicle occupants, who because of their differing viewing directions, may have only limited ability to view a display.
According to another feature of the invention, information can be emitted concerning only some of the operating elements of the vehicle, these operating elements being separately identified. It is possible for example, that for a subsequently installed radio set, no information can be displayed concerning the operating conditions which can be switched by means of the operating elements. Advantageously, the operating elements about which information can be emitted may therefore be correspondingly identified. This identification can, for example, be illuminated, so that it can also be seen at night.
Another embodiment of the invention has an assistance request element whose operation causes, with respect to subsequent operation of an operating element of at least one component, only information to be emitted concerning the operating condition which can be switched by means of this operating element in the normal operation.
According to still another feature of the invention, the assistance request element can be operated manually, and is provided with a key function as well as with a locking function.
The assistance request element is therefore constructed as a manually operable key/button whose operation causes the emission of information concerning the operating condition which can be switched in the normal operation by means of the operating element actuated next. Furthermore, the assistance request element is also designed so that it can be locked in an activating position. Thereafter, information is emitted concerning the operating conditions which can be switched in normal operation for all operating elements operated during the locked in activation. This is particularly advantageous if the user wants to obtain a
