Description

The invention relates to a method and an arrangement for Control and / or regulation of a load of a vehicle, e.g. a passenger or commercial vehicle.

Such methods and arrangements are well known. For example, reference is made to DE 44 07 475 A1. This is based on a setpoint for the of Drive unit to be delivered torque in addition to the load also the air / fuel ratio is affected. In particular a fine, very accurate adjustment of the engine torque, thereby the ride comfort improved, given. In addition to such Demands that the ride comfort or the exhaust emission improve today, other factors such as safety, Environmental protection and energy conservation, an essential role. This includes the protection of the population from noise pollution. With increasing traffic and always higher Settlement density, the requirements for reduction grow of harmful environmental effects caused by traffic noise. To protect the population from traffic noise and to Compliance with immission limits in accordance with the Traffic Noise Ordinance 16. BImSchV are usually public Roads laid around localities or appropriate speed limits given on the streets or even driving bans pronounced.

In JP 04238749 A, a method for minimizing the Noise level of an engine described using that the current vehicle speed and current position of the accelerator pedal, the speed ratio and the Throttle position of the engine controls.

The object of the invention is therefore to provide a method and a Arrangement for controlling and / or regulating a load of a Indicate the vehicle caused by the vehicle Noise emission or noise emission is improved.

The first object is achieved by a method for controlling and / or regulating an accelerating or decelerating torque acting load a vehicle, wherein by means of a recording unit, the instantaneous Load of the vehicle based on at least one farm size of the vehicle determined and by means of a control or Control unit the operating size as a function of a resulting from the current load of the vehicle resulting noise level controlled and / or regulated. By such Consideration of operating and / or ambient noise of the moving vehicle, in particular by the Load of the vehicle itself and its regulation are caused, can be the noise emissions caused by driving and immissions are significantly reduced. Furthermore allows the control of the noise level correlating Load an increase in ride comfort. Further is depending on the degree of the resulting from the process Noise reduction or noise emission limitation Ride also in noise-locked streets, inner cities and territories.

The noise-related operating variable control is preferred and / or control, which is the load and vehicle related noise emission reduced to the functions for Adjustment of the vehicle drive adapted. It is essential Here, that on the basis of the current load by means of Control unit (also called moment interface, hereinafter referred to as the control unit) a desired torque for controlling / regulating the vehicle as a function of Noise level and information about which dynamics this torque request should be set, given become. It is completely irrelevant which subsystems (Control systems, such as speed controllers) involved in the moment interface and like this be coordinated with each other. By the preferred use of noise-related characteristic fields for different, the operating variable representing control and / or control variables, where the requirements are different Dynamics and with different goals, can take account of the different subsystems become.

The invention is further based on the consideration that to comply with noise limits, e.g. in residential areas or near hospitals, the vehicle in terms of its noise emission should be limited. Conveniently, becomes the operating noise level Used as to be controlled or regulated operating size. As a result, in addition to the ambient noise by the currently delivered power conditional operating noise of Vehicle considered in the control or regulation of the power. Thus, the factors responsible for the noise the size of the business to be controlled or controlled are relevant to this regulation and / or control taken into account and influenced accordingly. For example is the choice of translation of a switchable or stepless adjustable transmission a noise-relevant factor.

Advantageously, as an operating variable, a speed, a Torque, a speed and / or an acceleration used. The speed change causes the torque curve with the aim of changing that at low speed Higher engine power is achieved, reducing noise emissions is kept very low. With others Words: At full load of the vehicle and low speed will be less noise generated by the vehicle. Alternatively or in addition be as operating size a translation level and / or a gear ratio in a stepless Power transmission arrangement used. Advantageously as the most important, the noise influencing operating size the acceleration is monitored and used. The to be controlled / regulated quantity, the desired acceleration the vehicle is currently being retrieved Load of the engine. If by calling the desired Acceleration exporting load a noise that would result over a certain limit is located, the control unit reduces the actual retrieved Load so far that the limit is not exceeded becomes.

In a preferred embodiment, for determining the relevant nominal value of the operating variable different characteristic fields deposited, in which the dependence of the noise level from the current speed, speed, Load and / or the selected shift can be mapped. A desired acceleration, for example, at low Load and high speed in a low gear be achieved while doing another (higher or lower) Cause noise levels as another map point, the same acceleration by means of high load at lower Speed runs in the higher gear ratio. Based on Characteristic fields, the setpoint torque is determined with others Set torques, for example from the transmission control, from a vehicle dynamics control or other subsystems of Drive control (e.g., from a digital map) becomes.

Advantageously, the noise level is based on the current Load on the vehicle and / or ambient noise determined. These are different curves for the noise level depending on the vehicle type, age, -motorization, -speed, -assembly, -acceleration for various road surfaces and / or tire parameters and / or meteorological events (e.g., wind, rain) detected and in Form of characteristic fields deposited, on the basis of which then the the current load of the vehicle representing noise level is determined. Alternatively or additionally Ambient and / or operating noise by means of the recording unit, e.g. by means of a microphone, recorded and processed. This is the result of the interaction of tires and Lane or vehicle body and wind resulting Sound emission detectable and can thus in the noise-reducing Control / regulation of the load are taken into account. In this case, the recording unit as a stationary and / or be implemented mobile sound detection unit. About that In addition, by means of such stationary and / or mobile Noise detection units uncontrollable noises of Environment are taken into account in the control / regulation (For example, in the case of rain, the maximum can be corrected upwards).

Conveniently, the noise level becomes a limit or monitored for a guideline value. For example, the maximum allowable noise levels for different areas, such as e.g. Residential area, commercial area, different. Compliance these predetermined limits for the maximum allowable Noise level is added to the control / regulation the size of the company. The location-related limits are e.g. stored in the form of a table in a database.

To a localized noise reduction of the moving vehicle Preferably, the operating size is in Dependent on the current position of the vehicle controlled and / or regulated. In doing so, corresponding limit values are set for the noise level for different geographical Coordinates taken into account in the control / regulation of the operating variable. As a result, for example, a relation to the usual noise reduction increased noise reduction in noise critical zones allows. This includes the receiving unit preferably a location system and / or a geographical Information system. Depending on the type and design of the recording unit may be the location system and / or the geographic information system be integrated or decentralized over one Interface be connected to the recording unit.

For example, serve stationary and / or mobile sound detection systems, e.g. Sound sensors, microphones. As sound sensors, for example Airborne or structure-borne sound sensors for detection used the air or structure-borne noise. advantageously, is the recording unit for detecting a speed, an acceleration (deceleration) and / or a drive torque for determining the current load of the vehicle intended. This is the result of the current load resulting noise level, for example, based on in a data memory stored characteristic fields determined.

Alternatively and / or additionally, a location system is preferred for determining the current vehicle position and / or an information system for determining a thereof resulting location-based noise level provided. This allows compliance with a maximum permissible noise level in one place, adding the operating size by a corresponding Setpoint is set.

1. Das Fahrzeug F fährt zunächst mit einer konstanten Geschwindigkeit v₁ und erzeugt dabei einen Geräuschpegel von G₁, der unterhalb des maximal zulässigen Geräuschgrenzwertes Gmax liegt. Der Fahrer 40 möchte mit voller Leistung auf eine Geschwindigkeit v₂ (v₂>v₁) beschleunigen und würde somit einen Geräuschpegel von G_1/2 erzeugen, der über dem Geräuschgrenzwert Gmax liegt. Die geräuschbegrenzende Steuerung oder Regelung der Steuereinheit 2 wählt jedoch eine reduzierte Last L_red, die während der Beschleunigungsphase von v₁ auf v₂ den Geräuschgrenzwert Gmax nicht überschreiten läßt.

2. Das Fahrzeug F fährt zunächst mit einer konstanten Geschwindigkeit v₁ und erzeugt dabei einen Geräuschpegel G₁, der unterhalb des maximal zulässigen Geräuschgrenzwertes Gmax liegt. Der Fahrer 40 möchte mit einer Wunschlast L_W auf eine Geschwindigkeit v₂ beschleunigen. Der aus der Geschwindigkeit v₂ resultierende Geräsuchpegel G₂ würde jedoch den zulässigen Geräuschgrenzwert Gmax überschreiten (G₂ > Gmax). Die geräuschbegrenzende Steuerung/Regelung wählt eine reduzierte Last L_red, die das Fahrzeug F bei einem Geräuschpegel G_1,2 < Gmax von v₂ auf v_max < v₂ beschleunigt. Bei v_max erzeugt das Fahrzeug F dann den maximal zulässigen Geräuschgrenzwert Gmax. Die geräuschbegrenzende Steuerung/Regelung der Last L_red verläuft von v₁ bis v_max unter Berücksichtigung von steigenden Fahrgeräuschpegeln, die Folge von höheren Fahrzeuggeschwindigkeiten sind.

3. Das Fahrzeug F fährt zunächst mit einer konstanten Geschwindigkeit v₁ und einem betreffenden Geräuschpegel G₁ in ein Wohngebiet ein. Der aktuelle Geräuschpegel G₁ überschreitet jedoch den für das Wohngebiet geltenden zulässigen Geräuschgrenzwert Gmax (G₁ > Gmax). Die geräuschbegrenzende Laststeuerung/-regelung geht daraufhin solange in den Motorbremsbetriebsmodus oder betätigt die Bremsen bis eine gegenüber v₁ reduzierte Geschwindigkeit v_max (v_max < v₁) mit dem zulässigen Geräuschgrenzwert Gmax (Gmax < G₂) erreicht wird.

Advantageously, three typical cases of load reduction are distinguishable:

1. The vehicle F initially moves at a constant speed v ₁ and thereby generates a noise level of G ₁ , which is below the maximum allowable noise limit Gmax. The driver 40 wants to accelerate at full power to a speed v ₂ (v ₂ > v ₁ ) and thus would produce a noise level of G _1/2 that is above the noise limit Gmax. However, the noise-limiting control or regulation of the control unit 2 selects a reduced load L _red , which does not exceed the noise limit Gmax during the acceleration phase from v ₁ to v ₂ .

2. The vehicle F initially moves at a constant speed v ₁ and thereby generates a noise level G ₁ , which is below the maximum allowable noise limit Gmax. The driver 40 wants to accelerate to a speed v ₂ with a desired load L _W. The resulting from the speed v ₂ Geräsuchpegel G ₂ would, however, the permissible noise limit Gmax exceed (G _2> Gmax). The noise-limiting controller selects a reduced load L _red which accelerates the vehicle F at a noise level G _1,2 <Gmax from v ₂ to v _max <v ₂ . At v _max , the vehicle F then generates the maximum allowable noise limit Gmax. The noise-limiting control of the load L _red runs from v ₁ to v _max in consideration of increasing driving noise levels, which are the result of higher vehicle speeds.

3. The vehicle F initially moves at a constant speed v ₁ and a respective noise level G ₁ in a residential area. However, the current noise level G ₁ exceeds the permissible noise limit Gmax (G ₁ > Gmax) applicable to the residential area. The noise-limiting load control / regulation then goes into the engine brake operating mode or actuates the brakes until a speed v _max (v _max <v ₁ ) which is reduced compared to v _{1 is reached} with the permissible noise limit value Gmax (Gmax <G ₂ ).

Depending on the type and design of the vehicle F is the output unit 10 for displaying the current control and / or control state the control unit 2 in the form of a cockpit arranged Screen. For example, means the output unit 10, the current vehicle position P (F), the environmental / vehicle related noise level G (U), G (F) and / or the operating size B, in particular their Sollund / or Actual value, as well as the current or desired load L represented.

FIG. 4 shows by way of example two vehicles F, each equipped with the arrangement 1, and a Drive on road 42. Along the road 42 to be traveled different zones with different noise sensitivity, e.g. a residential area 44, a hospital 46, a park 48, an industrial area 50 (factory with night shift), a forest area 52 and a school 54. By arrangement 1 (also called noise emission limiter or noise emission limiter is designated) by the respective control unit 2 of the vehicle F is a load L by noise-dependent control and / or regulating the operating size B, which one characterizing the respective area 44 to 54 Limit value Gmax for the total noise level G (G) = G (U, F) = Does not exceed G (U) + G (F). This is the sound-dependent Control and / or regulation of the operating size B as a function of from the area 44 to 54 to be traveled and / or executed as a function of time. For example is near the areas 44, 46 and 54 (residential area, Hospital or school) on day T usually a higher one Limit of Gmax = 65 dB (A) for the maximum allowable total noise level G (G) than at night N with Gmax = 45 dB (A). Near the areas 48, 50 is by means of the control unit 2, the associated vehicle 2 with respect to such the operating size B and the load L set that on Day T is the limit Gmax of 70 dB (A) and N at night Limit Gmax of 65 dB (A) as maximum allowable noise level is not exceeded. In contrast, in the areas 52 or 56 in the area near a highway, which outside noise-protected areas 44 to 50, 54, the noise-related control / regulation of the load L is switched off since in these areas 52, 56 there are no noise immission limits on the part of the Federal Immission Control Act (TA-noise) are given.
