Definitions
- the invention relates to a mobile transponder for a vehicle with an optical display.
- Such a key is known from DE 3740770 A.
- the visual display indicates whether the vehicle is locked. However, it is often necessary to obtain information about the location of the vehicle.
- the invention has for its object to provide a mobile transponder for vehicles, the visual display of which allows further information about the vehicle.
- the visual display now shows where the vehicle is located.
- a query signal is transmitted via the antennas, which results in a response from the vehicle in the form of a radio signal.
- This answer is evaluated in the transponder and output as optical information. Due to the directional characteristics of the antennas, it is possible to detect the location of the vehicle with regard to its direction in relation to the respective position and orientation of the transponder. This direction is signaled to the driver by a corresponding optical display.
- the optical display can be designed as a small display, for example an LCD display. The direction in which the vehicle is in relation to the mobile transponder can then be shown as an arrow within the display
- the directional information with the aid of lights, for example LEDs.
- These can be arranged in a circle, for example.
- the direction in which the vehicle is located can be determined in relation to the center of the circle.
- Two diagonally opposite ones can also be used LEDs are activated This enables the direction to be determined and displayed relatively often. This information is often sufficient. The driver only needs to withdraw from the two directions that are possible in the opposite direction to the actual direction
- the antennas not only determine the direction, but also actually the distance of the vehicle from the respective location.
- the vehicle user thus has information about how far from his respective location at which he is with his mobile transponder , the vehicle is removed
- FIG. 1 shows a first exemplary embodiment of the invention and FIG. 2 shows an alternative to the exemplary embodiment of FIG. 1
- a mobile transponder 1 shown in b) with its individual parts is integrated in a mechanical vehicle key 2 (a)).
- the transponder 1 contains four antennas 11, 12, 13 and 14, of which two each 11, 12 and 13, 14 by one in between horizontal shielding 3, 4 are separated from one another. Due to the effect of the shielding plates, the antennas have a directional characteristic, which are symbolized by lobes 11 '-14' shown in broken lines
- a switch 5 is assigned to the antennas 11 to 14, by means of which the antennas are activated in sequence by an evaluation unit 6.
- the antennas each send out a query signal upon a manually issued command, which is picked up by the searched vehicle and by outputting one Answer signal is answered by the vehicle. This command is given by pressing a remote control button VR in the key head 9
- these response signals are entered one after the other into the evaluation unit 6 via a corresponding processing circuit 7. Due to the directional sensitivity of the antennas shown in c), the evaluation of the total of 4 response signals results in information about the location of the vehicle Shown with the aid of an optical display 8, which is arranged in the surface of the key head 9.
- the display 8 consists of LEDs arranged in a circle around a center 8 '
- the LED located in the direction of the vehicle sought and the LED located in the center are activated.
- the imaginary connection of these LEDs determines the direction in which the vehicle sought is located
- the arrow With an arrow arranged between the two activated LEDs, it is also possible to display a measure of the distance of the vehicle. At a short distance, e.g. less than 50m, the arrow is strongly illuminated, but at a greater distance, a dim measure of the distance results from a strength comparison of the response signals recorded with corresponding antennas 11 and 12 or 13 and 14. Assuming that the signals from the sought vehicle are emitted with the same intensity, the quotient of the intensity of the corresponding response signals and results from the evaluation of these quotients with the individual intensity provides information about the distance of the vehicle sought from the transponder 1
- three antennas 21, 22, 23 are arranged instead of four antennas. These also have the directional characteristics shown in dashed lines. With a corresponding sequence of question and answer signals, it is transmitted in succession with each of the antennas or as a response from the vehicle are recorded, again possible to obtain the desired direction and, by comparing the intensity of the respective signals, their distance as information and to display them in an LED circle by means of a visual display such as an arrow in a display or as shown in FIG. 1
