As FIG. 2 shows, the handle can have a two-part design, consisting, for example, of a base shell 21 and a cover shell 22, between which a space 23 is present to hold a separate electrical component 30. In the present case, the handle 20 is designed as a so-called “pull” handle, which has a pivot bearing 25 at one end and a shaft 26 at the other end, the shaft acting via intermediate elements on the associated lock 15 in the door 11. The handle 20 is advisably located near a grip well 16 in the outer panel of the door 11, so that an intermediate space 17 is created there between the handle 20 and the outer door panel of the vehicle 10.
Each of the conductive areas 41-43 has a different function to fulfill. After the finished unit 30 has been installed in the handle 20 and connected to the required components in the vehicle 10, these areas form the electrodes 51, 52 of two capacitative sensors 61, 62, each with its own manner of operation, as will be explained in greater detail on the basis of FIGS. 3 and 6. The electrical cable 58 projecting from the unit 30 in FIGS. 2 and 5 and the contact parts 59 are used for this purpose. The one electrode 51 produces a first electrical field 50 according to FIG. 3 extending toward the body of the vehicle 10; this field is created in the previously mentioned intermediate space 17 between the handle 20 and the well 16. This field 50, as previously mentioned, will therefore be called in brief the “inner field”, and this electrode 51 will be called the “inner electrode”. This inner electrode 51 is shielded from the other electrode 52 by a third conductive surface 43, which is grounded, and which, in the folded state 40 of FIG. 6, is located between the other two electrodes. The third surface therefore functions as the shielding 53.
When voltage is applied, the other electrode 52 generates a second electrical field 60, according to FIG. 3, directed toward the outer environment of the vehicle. Because this field 60, from the perspective of the handle 20, is directed outward, it will be called the “outer field”, as previously mentioned. It is independent of the inner field 50. The electrode 62 used to generate this outer field 60 will therefore be called correspondingly the “outer electrode”. The way in which the inner and outer fields 50, 60 work can be explained best on the basis of the schematic diagram of FIG. 1.
The mobile part 64, in the form of a “check card” as indicated schematically in FIG. 1, is carried by the authorized person. Transmitting and receiving units, a memory circuit, power sources, and control components (not shown) are integrated into this card in a manner known in and of itself. When the authorized person comes within a certain suitable distance of the vehicle 10, the stationary part 55 can initiate a mono- or multi-directional data exchange 65 by electromagnetic means with the mobile part 64 of the access authorization device. The inner field 50 and the outer field 60 are generated at the handle 20 by this time at the latest. When the authorized person now puts his/her hand behind the handle 20 of FIG. 3, the inner electrical field 50 present there is altered. This is detected by the associated first sensor 61, which then switches the lock 15 and, in the case of a central control unit, additional locks or all of the locks of the vehicle 10 to their release position. The lock 15 has already been unlocked by the time the authorized person has gripped the handle 20. Since the door 11 or 12 has now been released, pulling the handle 20 outward has the effect of opening the door. Because the function of this first, lock-releasing sensor 61 is to switch the lock 16 the position in which the door can be opened, it will be called the “opening sensor,” in the following.
When the authorized person leaves the vehicle 10, he or she can, if in possession of the mobile part 64, cause the locks 15 to lock themselves automatically. To close the opened door, the hand will approach the handle 20 from the outside and thus arrive in the area of the outer field 60. The inward-moving hand causes a change in the capacitance, which is detected by the second capacitative sensor 62. In this case, the control unit will switch the lock 15 or all of the locks into their locking position. After the authorized person carrying the mobile part 64 has left the vehicle 10 and shut the doors 11, 12, he/she can thus lock them so that they cannot be opened by unauthorized persons. The second sensor 62, which is operating in this case, can therefore be called in an analogous manner the “locking sensor”.
