Definitions
- the invention relates to an arrangement and a method for generating a simulated operating noise of a drive assembly of a vehicle, comprising the drive having a continuously variable transmission, a noise generator and a noise output device.
- the operating noise of a vehicle may be influenced by a system comprising an electronic driver and a loudspeaker, for example on an exhaust, and operating sounds of a vehicle may be simulated electronically a given or assumed speed of the drive unit is known for example from US 6,859,539 B1.
- Acceleration may be useful to maintain the speed or even a reduction in the speed, which is done by the continuously variable transmission to operate the engine in an optimal load range. This can lead to an unusual for the driver engine noise, since this does not correspond to the usual speed increase during acceleration. Disclosure of the invention
- the driver of a vehicle is given an acoustic driving feel which corresponds to the driving experience familiar from conventional vehicles despite the optimized use of a continuously variable transmission.
- an arrangement for generating a simulated operating noise of a drive unit of a vehicle is provided. It is contemplated that a noise generator will generate or influence the operating noise regardless of the actual speed and / or the actual load of the power plant. The operating noise therefore does not follow the unusual for the driver speed curve of the continuously variable transmission, but conveys the impression of a conventional vehicle acoustically.
- the drive unit here consists of the engine, in particular an internal combustion engine and / or an electric motor, for example, a hybrid arrangement and the transmission, in particular the continuously variable transmission, and is an exhaust system, in particular the exhaust and the corresponding exhaust pipes and resonators or mufflers, connected.
- the noise generator is an electronic synthesizer arrangement into consideration, which generates or changes the operating noise on request, and / or an electronic device that reads the operating noise from memory modules.
- the noise output device according to one embodiment comprises an amplifier for the operating noise as well as a loudspeaker or another suitable one
- Output device that converts the signals of the noise generator in sound waves that are audible by the driver.
- the noise generator generates this noise of a conventional vehicle, in particular one that has no continuously variable transmission.
- the noise generator can cause a distortion of the actual speed in an acoustic sense. If the operating noise is influenced, it is to be understood that an existing operating noise is superimposed by the electronic operating noise, so that a sum of the two operating noise is perceived by the driver as a common operating noise. In this case, it can be provided, in particular, that existing frequencies of the existing noise that are active for influencing are damped or amplified.
- the noise generator simulates operating noise of a stepped transmission.
- a stepped transmission here both manual and automatic transmissions into consideration.
- the turning out of a certain speed band, which is associated with a respective gear takes place with a corresponding drop back the speed when switching to a next higher gear or with a higher speed band when switching back to a smaller gear. Consequently, in order to acoustically indicate an abrupt change of the rotational speed which is acoustically familiar to the driver, a gear change simulation is carried out.
- a falsification of the actual speed (indicated for instance by a tachometer) can support the simulated gear change.
- the operating noise includes exhaust noise. From the driver not only mechanical noises of the engine, such as the internal combustion engine or an electric motor, and the transmission, but also exhaust noises are perceived. Such exhaust noise may also be included in the operating noise. In particular, it is also possible directly in parts of the exhaust, for example, by arranging the noise output device in or on a silencer of the exhaust, to give rise to the operating noise at the usual place or actively influence by damping and / or amplification of existing frequencies.
- the operating noise is simulated as a function of a detected torque request by a driver of the vehicle.
- a moment request is here a moment request, in particular a rapidly changing torque request, for example when an accelerator pedal of the vehicle passes through.
- kickdown switching back the automatic transmission in a next lower gear to increased
- the operating noise is thus simulated in such a way that only a torque request of the driver is taken into account, but not the actual speed of the drive unit.
- the driver's noise maintenance attitude is advantageously met.
- detection of the torque request takes place via detection of an accelerator pedal position.
- the accelerator pedal of the vehicle therefore has a sensor or an already present on the gas pedal sensor is used, which provides information about the position and / or a change in the position of the accelerator pedal, from which a torque request can be closed by the driver.
- a rate of change of the accelerator pedal position can be detected.
- an interface is preferably configured on the arrangement according to the invention, via which the arrangement is connected to a sensor, based on the signals of the detection of the accelerator pedal position is possible.
- a vehicle with an arrangement according to one or more of the embodiments described above is proposed.
- Such a vehicle allows, despite very effective energy utilization by using a continuously variable transmission without limitation to certain speed bands, but taking advantage of its full speed spectrum, providing a familiar for the driver operating noise and thus from unconscious influences of an unfamiliar noise free driving.
- a method for generating a simulated operating noise of a drive assembly of a vehicle comprising the continuously variable transmission having unit, wherein it is provided that a noise generator, the operating noise regardless of the actual Speed or / and the actual load of the drive unit generated or influenced. Accordingly, the operating sound made audible to the driver via the noise generator and a sound output device does not follow the actual load or rotational speed of the power plant, thus being decoupled from the load and the rotational speed.
- Figure 1 shows an arrangement for generating a simulated simulation
- Figure 2 is a graph of a simulation of a stepped transmission.
- FIG. 1 shows a schematically illustrated vehicle 1, namely a passenger car 2.
- This has a drive unit 3, which has an internal combustion engine 4 and a continuously variable transmission 5.
- the internal combustion engine 4 connected downstream is an exhaust line 6 preferably with a pre-silencer 7 and / or a rear muffler 8.
- the power of the engine 4 is via the continuously variable transmission 5 to a drive train 9, for example by means of a propeller shaft 10, to the rear wheels 11 to the drive guided.
- a driver 12 can transmit a desired torque or a torque request to the internal combustion engine 4 via a gas pedal 13 known from the prior art.
- the vehicle 1 further comprises an arrangement 14 for generating a simulated operating noise 22 of the drive unit 3, wherein the arrangement 14 via an interface of the arrangement with the gas pedal 13 via suitable electrical connections 15 and / or via a non-illustrated System bus of the vehicle and / or with a control unit, not shown, of the vehicle is in communication.
- the arrangement 14 is preferably an electrical and / or electronic control unit.
- the arrangement 14 comprises a noise generator 16, for example a synthesizer 17 for request-dependent generation of noises in real time or, not shown, a sound storage database, for example memory chips, not shown, for reading out noise.
- the arrangement 14 comprises a noise generator 16, which is connected via a further interface of the arrangement to a noise output device 18, in particular an electromechanical transducer 19, for example a loudspeaker 20.
- the noise output device 18 generates the operating noise 22 generated by the noise generator 16 for the driver 12 audible and especially in the low-frequency, here also in particular in the infrasound area felt.
- a further electromechanical transducer 19 may also be associated with the exhaust line 6, for example the pre-silencer 7 or, not shown, the rear silencer 8.
- This allows the generation of operating noise 22, in particular of exhaust noise 21, at the for the emergence in the state of Technology usual place, namely in the exhaust line 6.
- the operating noise 22 of the drive unit 3 then includes the exhaust noise 21 and is characterized in particularly suitable cases of this.
- the operating noise 22 is hereby dependent on a
- different speed bands are repeated, as is the usual speed development when switching through a stepped transmission.
- the driver 12 is here given the impression not to drive with the continuously variable transmission 5, the speed varies continuously to exploit its full potential and the potential of the engine 4, even contrary to the usual perception of the driver 12, so for example when torque request for Accelerate instead of one Speed increase, as the driver 12 is accustomed to stepped transmissions, however, a speed reduction can take place.
- the simulation of the stepped transmission is made via the operating noise 22 which is generated and reproduced here by the arrangement 14. whereas the noise by the internal combustion engine 4 and the continuously variable transmission 5 substantially recedes.
- FIG. 2 schematically shows the simulation of the operating noise 22 as a graph 23 of an acoustic rotational speed r a as a function of the vehicle speed v c obtained by means of the torque request by the driver 12.
- the illustration shows the acoustic speed r a during acceleration of the vehicle 1, as obtained from the arrangement 14 for the simulation of a stepped transmission (reference numerals which are not reproduced in FIG. 2 can be found in FIG. 1, which is to be used for the sake of clarity).
- the acoustic curve of a speed increase namely the acoustic speed r a , simulated by switching gear stages.
