Definitions
- the invention relates to a method and an apparatus for generating of noises, in particular of switching noises electrical Switches in motor vehicles.
- the switch in motor vehicles has no acoustic signal for the user Feedback whether the desired switch actually switches. So is z. B. the driver used to that after turning on Direction indicator a sound in time with the flashing relay switching operations sounds.
- the sound used to be in the electromechanical flasher relay by closing or opening the Switch contacts generated. Because today's electronic flasher relay is silent switch, additional procedures are used and are additional Devices are provided for generating or generating switching noise imitate.
- Known methods and devices produce this Switching noise either through a so-called knocker, which is similar how an electromechanical relay is constructed or by a electronic circuit that has one tone or more periodic tones delivers.
- a disadvantage of the knocker is the high price of the electromechanical component and the required installation space. Disadvantageous in the known electronic methods and circuits, it is that the periodic tones do not sound like a switch and therefore from Drivers either not as an indication of the function of the Switch, in particular the flasher relay rated or as unnatural and to be annoying.
- the object of the invention is therefore a method and a device specify with the noises, in particular switching noises from Switches in motor vehicles can be realistically simulated.
- a device has a Storage unit for storing frequency values, a frequency generation unit to generate frequencies corresponding to the read frequency values and a processing unit for sequential readout of the frequency values from the memory unit and sequential reading into the frequency generating unit and one Converter unit that is generated with that in the frequency generating unit Frequencies is driven and so the generated frequencies in Converts sound waves with the corresponding frequencies.
- the sound converter When simulating switching noises, the sound converter becomes Advantageously controlled only in the time that a listener with one a switching noise from a real event can perceive. This saves a lot of storage space and one Processing unit is much less stressed, so that it is also different Can perform tasks.
- Allocate volume is one of those Driving speed of a motor vehicle dependent noise generation feasible and secondly an even more realistic one Noise simulation.
- FIG 1 are the frequencies generated in accordance with the invention
- An acoustic flashing relay is shown using the example.
- a mechanical one Flasher relay generates one when the two contacts meet bright tone, whose sound emulated by the invention sequential frequencies is realized, which in Figure 1 with TIC 1 - TICn are designated.
- the more dull one created when the two contacts were loosened or lower tone is simulated according to the invention with frequencies that are designated with TAC 1 - TACm.
- the lighter tone TIC is perceived by the human ear for about 5 msec. Therefore, this tone must also be reproduced 5 msec.
- the duller tone TAC is perceived by the human ear for about 10 msec and is reproduced accordingly for a longer time.
- the frequencies used depend on the noise to be simulated and on the frequency response of the transducer unit, which converts the electrical frequencies into sound waves. A clue to the frequencies to be selected can be found by spectral analysis of the noise to be simulated. More than two different frequencies can also be used to emulate a tone.
- FIG. 2 shows a memory unit 1, a processing unit 2 in the form of a Microprocessor, a frequency generating unit 3 and Converter unit in the form of a loudspeaker 4.
- the microprocessor 2 To produce the lighter tone TIC, the microprocessor 2 first reads the value TIC 1 from memory 1 and loads it into the Frequency generating unit 3, the correspondingly loaded frequency until another command is generated. The microprocessor 2 can Dedicate other tasks first. Reads after a millisecond he the value TIC 2 from the storage unit 1 and loads it into the Frequency generation unit 3. The frequency generation unit then ends 3 the frequency which corresponds to the value TIC 1 and generates the frequency that corresponds to the value TIC 2. The microprocessor 2 reads a following value from the table every millisecond, so far comes to the value TIC n.
- the microprocessor 2 After the frequency f1 is generated one msec, which corresponds to the value TIC n, the microprocessor 2 gives the Frequency generation unit the command to start the frequency generation break up.
- the converter unit in the form of the speaker 4 converts the generated frequencies in corresponding sound waves so that a Listeners heard a TIC.
- the microprocessor is 2 the value TAC 1 from the storage unit 1 and loads it into the Frequency generation unit 3, which is stored in TAC 1 Frequency value generated.
- the microprocessor 2 reads the value TAC stored value 2 from the memory unit 1 and loads him in the frequency generation unit 3, which the generation in TAC 1 corresponding frequency ended and with the TAC 2 corresponding Frequency starts. The procedure continues accordingly until the Microprocessor 2 1 msec after loading the frequency TACm the Frequency product unit 3 gives the command to start frequency generation break up.
- FIG 3 shows a possible circuit for controlling a speaker 4 as a converter unit with a square wave signal.
- the loudspeaker 4 has one connection to the supply span VCC and its other connection to a capacitor C, the second connection of which is connected to the collector of a transistor T.
- the emitter of the transistor C is connected to the ground potential via an emitter resistor R E.
- a resistor R p is arranged between the supply voltage VCC and the collector of the transistor T.
- the square-wave signal f n generated in a frequency generation unit 3 reaches the base of the transistor via the series resistor R V. If the signal f n has a high level, the transistor T turns on, the loudspeaker 4 is connected to the ground potential via the capacitor C and its membrane picks up.
- the transistor T blocks and the capacitor C discharges through the resistor R p and the loudspeaker 4, so that the membrane of the loudspeaker 4 is pulled in the opposite direction.
- the loudspeaker oscillates in time with the square-wave signal f n .
- the harmonics of the square wave signal are so strongly attenuated by the loudspeaker 4 that they are barely audible.
- the invention is not based on the above Embodiment limited. For example, also Simulate switching noises from other switches, e.g. B. one Acknowledging drivers acoustically, for example, can also Simulate switching noises from other switches and e.g. B. one Acoustic feedback to motorists, for example, that a film switch or has switched an inductive or capacitive switch.
- the Noise simulation is not based on the simulation of switching noises limited. Other sounds can also be simulated, for example for other information and / or warning purposes.
