Definitions
- the invention is based on a steering wheel according to the preamble of claim 1.
- Steering wheels of this type are conventionally known.
- such fiber optic sensors are used in the window frame or in the front of an electrically operated window.
- the sensors switch off the window lift motor as soon as a risk of being caught is detected when the window pane moves upwards.
- the risk of pinching is detected by an electronic control device in that the pressure acting on the optical fiber in this state causes a change in a light signal that is introduced into it and received by a sensor. This Change is evaluated by the control unit and converted into a signal to switch off the window motor.
- the invention is based on the idea of using a fiber optic sensor for the targeted triggering of vehicle-side functions, for example of lights, horns, wipers etc. by the driver.
- the sensor is expediently arranged on the steering wheel, in particular on the steering wheel rim. The functions are triggered by an increased pressure impulse from the driver on the steering wheel rim.
- grip sequences could be defined from a plurality of pressure pulses in quick succession, by means of which even several different vehicle-side devices can be controlled with a single sensor. The ones that have been eliminated
- Switches on the dashboard of a motor vehicle increase the clarity of the dashboard and reduce parts and assembly costs while increasing driving safety.
- FIG. 1 shows in simplified form the arrangement of the fiber optic sensor and the evaluation circuit on a steering wheel.
- FIG. 2 shows the essential components for signal generation, acquisition and evaluation in a schematic signal flow diagram.
- the steering wheel 10 shown in FIG. 1 has an annular steering wheel rim 11, which is connected to a centrally arranged steering wheel hub 13 via a plurality of radially extending steering wheel webs 12.
- An optical fiber 14, which covers the entire circumference of the steering wheel rim 11, is wound in a coil shape around the steering wheel rim 11.
- the two ends of the optical fiber 14 run parallel along the steering wheel webs 12 to the steering wheel hub 13.
- At the first end of the optical fiber 14 there is an unrecognizable transmitter 16, the emitted light signal of which is also received by a sensor 18, also not shown.
- the transmitter 16 and the pickup 18 are in one
- Integrated evaluation circuit 15 which processes the received light signals into a driver signal 20.
- FIG. 2 shows, as one of the essential components of the evaluation circuit 15, a transmitter 16 arranged at the first end of the optical fiber 14.
- An excitation signal transmitter 17 sends a control signal 17.1 to an excitation signal generator 17 which sends a signal correlator 19 in parallel.
- the light signal 16.1 then generated by the transmitter 16 is polarized by a polarizer (not shown) before it enters the optical fiber 14 and passes along the optical fiber 14 to a photosensitive pickup 18 arranged at its opposite second end.
- This pickup 18 converts the received light signal 16.2 into a response signal 18.1 um, and forwards this to the signal correlator 19.
- the control signal 17.1 for the transmitter 16 and the response signal 18.1 of the sensor 18 are compared with one another.
- the signal correlator 19 From the differences in the polarization between the two signals, the signal correlator 19 generates a correlation signal 19.1, which is converted by an evaluation logic unit 20 connected downstream of the signal correlator 19 into driver signals 20.x for controlling vehicle devices not shown.
- the polarization differences between the control signal 17.1 of the transmitter 16 and the response signal 18.1 of the sensor 18 are due to physical Laws that are described in detail in the document DE-OS 33 11 524 are due to the effects of force or pressure on the optical fiber 14. These pressure or force effects generated by the driver deform the casing of the steering wheel 10 and, along with it, the optical fiber 14 in an infinitisimally small area.
- the evaluation circuit 15 would have to recognize grip sequences from short successive pressure pulses, to which various vehicle-side devices are assigned.
