Definitions

  • the invention is based on a device for activating user-specific settings according to the type of the independent claim.
  • a device is already known from EP-A 924 123, with the aid of which certain user-dependent settings of rear-view mirror adjustment drives, seat adjustment drives, air conditioning settings or radio settings are activated.
  • the user recognition takes place with the help of a fingerprint sensor. If the corresponding user is verified using the fingerprint system, the settings for the convenience functions assigned to this user are automatically activated.
  • the object of the invention is to carry out a simple deactivation of the adjustment processes in a fingerprint sensor system. This task is solved by the features of the independent claim. Advantages of the invention
  • the device according to the invention for activating user-specific settings comprises at least one fingerprint sensor, the sensor signal of which compares a signal evaluation for user identification with at least one piece of reference information. At least one setting is assigned to at least one user of an adjustable component. A controller is provided which activates the adjustable component in the sense of the setting assigned to the recognized user.
  • detection means are provided that detect the presence of a finger on the fingerprint sensor, the activation of the adjustable component taking place depending on whether a finger was detected as being present. With the aid of the recognition means, it is possible to immediately stop the adjustment process of the adjustable component when the finger is no longer on the fingerprint sensor. This can immediately interrupt safety-related adjustment processes.
  • the evaluation of the sensor signal of the fingerprint sensor is used as the recognition means. Since the fingerprint sensor is already provided for user recognition and activation of the user-dependent settings, no additional hardware is required for the recognition means. Appropriate evaluation algorithms are used to determine whether the finger is still on the fingerprint sensor. This evaluation logic is already available for user identification. This device is thus characterized by a simple and inexpensive construction.
  • a capacitive sensor is provided as the detection means. Depending on the presence of the finger, this detects any changes in capacitance which are used by a downstream evaluation electronics for presence detection. The capacitive sensor does not have to be touched directly by the user.
  • the detection means is implemented by a switch which can be actuated by the finger.
  • a switch which can be actuated by the finger.
  • Such a push button switch can be easily integrated into the fingerprint sensor. The reliability of this detection system is very high.
  • FIG. 1 shows a block diagram of the device according to the invention
  • FIG. 2 shows a flow diagram to illustrate the mode of operation of the device according to the invention.
  • a fingerprint sensor 10 outputs a sensor signal 12 and a switching signal 13 to a signal evaluation 14.
  • a reference list 15 is stored in the signal evaluation 14, in which at the first position a first reference information UREF identifying a first user, in the second position a second reference identifying a second user Reference information U2REF and an nth reference information UNREF identifying an nth user are stored at the nth position.
  • the signal evaluation 14 outputs user information 16 and a finger presence signal 18 to a controller, an item referred to as comfort control device 20, as the output signal.
  • the comfort control device 20 contains a memory 21 for user settings.
  • a first setting E1 is stored for the first user or the associated first reference information UlREF, and a second setting E2 etc.
  • the comfort control device 20 generates corresponding control signals for adjusting drives 24 as an example of user-adjustable components.
  • Fingerprint sensors 10 record the typical characteristics of a fingerprint, for example optically or capacitively.
  • the associated sensor signal 12 is processed by the signal evaluation 14 according to the method described in FIG. 2.
  • a step 101 the sensor signal 12 is read.
  • the system already knows a number of users based on the reference information UlREF, U2REF, UNREF.
  • the signal evaluation 14 now determines whether the read sensor signal 12 can be assigned to an already known user on the basis of the reference information UlREF, U2REF, UNREF.
  • the signal evaluation 14 compares the sensor signal 12 with the first element of the reference list 15, namely the first reference information UlREF.
  • the signal evaluation 14 thus uniquely assigns a specific user to the sensor signal 12 based on the reference information UlREF, U2REF, UNREF, step 109
  • the reference information UXREF determined in this way is forwarded to the comfort control device 20 as user information 16.
  • the reference list 15 can be rearranged in step 110 in order to accelerate the next user identification.
  • the reference list pointer i could be set to the last identified reference information UXREF for the next identification process.
  • the signal evaluation 14 was to compare the sensor signal 12 to be newly read in with the last reference information UXREF which caused a match.
  • the frequency of the registered users could serve the reference list 15.
  • the reference list 15 is now sorted by frequency, ie the reference information with the highest frequency is placed in the first position and so on.
  • the signal evaluation 14 now first compares the sensor signal 12 with the reference information at the first position in the reference list 15, that is to say with the reference information which has recorded most of the usage processes. This increases the likelihood that a frequent user will be recognized again quickly, and the frequency of use can also be used as a criterion for which reference information should be deleted in the case of a new user profile and limited storage space. In this case, the reference information with the lowest frequency of use is removed. This minimizes the number of new users to be trained.
  • the signal evaluation 14 transmits, as user information 16, the first reference information UlREF which corresponds to the sensor signal 12.
  • the comfort control device 20 receives the user information 16 and searches in the memory 21 for the user setting whether the transmitted user information 16 is present there in the form of the reference information UlREF.
  • the first setting E1 is assigned to the first reference information UREF, and the second setting E2 to the second reference information U2REF.
  • the comfort control device 20 reads out this first setting E1 and activates the adjusting drives 24 in the sense of this first setting E1.
  • the adjusting drives 24 can be, for example, in the driver or front passenger seat Move the motor vehicle into the position indicated by the first setting El.
  • the adjusting drives 24 could also be used to adjust interior and / or exterior mirrors or dimming devices. However, it is not absolutely necessary that the comfort control device 20 controls adjustment drives 24. It could also specify the settings E1, E2 for climate control devices or radio control devices, for example in order to activate certain interior temperatures that the user stored during the last operating process or to select radio stations that are preset depending on the user. However, this should only be mentioned as an example for possible adjustable components.
  • recognition means 10, 14 are now provided, which detect the presence of a finger on the fingerprint sensor 10.
  • the recognition means are implemented by the fingerprint sensor 10 and the signal evaluation 14.
  • the signal evaluation 14 continuously checks the sensor signal 12 provided by the fingerprint sensor 10 to determine whether it approximately matches any pattern that is characteristic of the presence of a finger on the fingerprint sensor 10. As long as this is the case, the signal evaluation 14 outputs a finger presence signal 18 to the comfort control device 20.
  • the finger presence signal 18 has a binary state. For example, it has the value logical one if the signal evaluation 14 has identified a finger that is present on the basis of the pattern comparison.
  • This finger presence signal 18 is now used by the comfort control device 20 to lock the corresponding actuation of the adjusting drives 24 by means of an AND link.
  • the activation of the adjusting drives 24 is only permitted as long as the finger presence signal 18 has the value logic one and thus indicates that there is still a finger on the fingerprint sensor 10.
  • the user removes the finger from the fingerprint sensor 10, the signal evaluation 14 recognizes this immediately and thereupon changes the finger presence signal 18 from logic one to logic zero. Because the activation signal for the adjusting drives 24 is linked to the AND with the finger presence signal 18, the activation of the adjusting drives 24 is immediately prevented.
  • finger presence detection it is not necessarily necessary for the detected sensor signal of the control element 22 to exactly match reference information stored in the reference list 15. This can shorten the processing time of finger presence detection. If the finger is placed again on the fingerprint sensor 10, the activation of the adjusting drives 24 in the sense of the previous setting E1 is resumed. This may take place until the adjusting drives 24 have reached the setting positions E1, E2 specified as reference values.
  • a capacitive sensor which is arranged in the vicinity of the fingerprint sensor 10 could also serve as a further alternative detection means for the presence of a finger. Depending on the distance of the finger from the capacitive sensor, its total capacity is influenced depending on the distance. If the finger moves too far from the capacitive sensor, this is recognized on the basis of the capacitance evaluation and the finger presence signal 18 is then changed accordingly to the logic zero state.
  • a switch contact that can be activated with the fingerprint sensor 10 could be provided as a further alternative finger recognition means. If the user places his finger on the fingerprint sensor 10, he also actuates this switching means. The output signal of this switching means, as finger presence signal 18, in turn reaches the grain control device 20. This device presence signal 18 is further processed as already described.
