Description
Technical field
The present invention relates to a kind of method and apparatus that is used for regulating the audio frequency apparatus volume of automobile.
Background technology
Now, comprise that the audio frequency apparatus of various playback modes (for example CD Player, broadcast receiver, mp3 player or navigation system) all belongs to the standard device of automobile.In scope of the present invention, term " audio frequency apparatus " should be understood that, it comprises any type ofly having being used for amusement or the device of information being provided of player function.Especially, also should comprise new-type entertainment systems, as long as they are installed in the automobile by this title.
This class audio frequency apparatus is favourable and comfortable on the one hand, but they still have shortcoming, that is, their operation often has a negative impact to the attentiveness of driver on road traffic.In this respect, especially the volume adjusting is verified is problematic in some occasion.Therefore carried out multiple improvement, to reduce described adverse effect.
For example in EP 0319777B1, provide a kind of Method and circuits device of in automobile, automatically regulating effective sound signal volume according to interference noise.According to the method for describing there, not only detect useful signal but also detect the interference noise that occurs at automobile by a microphone that is arranged in inside, automobile visitor railway carriage or compartment, for example engine or air-blower noise, and produce the resultant signal that is used to form the conditioning signal of regulating volume from these signals.Therefore can automatically and need not the operator and carry out the volume adjusting of useful signal according to the intensity ground of interference noise with intervening.Here, the method allows to consider at the loud speaker that sends useful signal and is used to regulate the transmission range that exists between the employed microphone of volume.
A kind of circuit arrangement that is used for additional information is inserted into the playback of audio signal is disclosed in DE 4410532B4.The sort circuit device for example is used in the playback set that Tour Bus exists the microphone notice being inserted in the running entertainment.Described circuit arrangement can be by making insertion the level match of voice messaging always clearly voice messaging is carried out playback in the level of running entertainment.So the driver who makes Tour Bus less disperses the attentiveness to traffic events.
Said method and system relate to because the dispersion of the driver attention that causes with the irrelevant extra noise of the residing driving situation of vehicle driver that occurs in automobile visitor railway carriage or compartment.
But in road traffic, often occur requiring the vehicle driver to improve the situation of attentiveness.What be worth expectation is, provide a kind of may scheme, in requiring to improve the situation of attentiveness, adjust the volume of the audio frequency apparatus that is arranged in automobile by it.
Summary of the invention
This purpose is by being achieved in accordance with the method for claim 1 and according to the device of the described audio frequency apparatus volume that is used for regulating automobile of claim 9 with according to the described system of claim 11.Preferred embodiment provide in the dependent claims.
A kind of method that is used for regulating the audio frequency apparatus volume of automobile comprises following steps: detect the numerical value that at least one is used to characterize the physical parameter of motor racing; The numerical value of detected at least one physical parameter and predetermined threshold value at this parameter compared and, reduce the audio frequency apparatus volume when detected numerical value during above predetermined threshold value.
In other words, according to the embodiment of the present invention one or more parameters are estimated, these parameters have changed meaning under the situation that will improve driver's tensity to compare with normal travel conditions.Therefore provide a standard of judging travel conditions automatically, judge automatically according to this and carry out the automatic adjusting of automobile audio apparatus volume.This can be continuously or off and on (for example with uniform interval) detect the numerical value that characterizes vehicle motion parameters.
Automatically reduce the audio frequency apparatus volume or close audio frequency apparatus fully when therefore, under dangerous situation or in the bounds of physics, travelling.The driver can strengthen the attentiveness for traffic then, can reduce traffic accident with this.In addition, other passenger in the automobile obtains the feedback about automobile travel conditions of living in, and this and driver or driver are irrelevant to the evaluation and the behavior thereof of this travel conditions.
As the physical parameter that characterizes motor racing, can use one or more following parameters without limitation: car speed, automobile longitudinal acceleration, vehicle lateral acceleration, automobile floating angle or instantaneous coefficient of friction at this.Can certainly use other physical parameter of the instantaneous transport condition that depends on automobile and/or its environmental condition (for example crosswind influence (cross force) etc.).
With regard to car speed, for example known for a long time so-called " the Di Sigao person of driving fast (Discoraser) " phenomenon.This refers to, by the psychologic acoustics influence of loud music to driver or driver's generation.High noise level is here impelled with too fast speed and is travelled.Use car speed according to the present invention is as the execution mode that plays the physical parameter of sign effect, and when surpassing certain velocity level, the audio frequency apparatus volume reduces or audio frequency apparatus cuts out.Being " first direction " through threshold value in this case, just passing through threshold value from bottom to top, in other words, is exactly to surpass threshold value.Therefore can interrupt the frequent feedback that occurs for the driver: loud music → aggressiveness or scatterbrained drive manner, continue to quicken.
With regard to automobile longitudinal and transverse acceleration, they are for example being overtaken other vehicles, and brake or change when moving to increase, that is, requiring the driver not increase under the distractive situation.Here " first direction " also is to pass through limiting value (therefore surpass threshold value towards negative direction under brake is the situation of negative acceleration, also be represented as from bottom to top and pass through) from bottom to top.
Actual coefficient of friction is a parameter, and the decline of this parameter shows that potential hazard increases.Coefficient of friction for example acutely descends under the situation of thin ice or humidity.In this case, " first direction " of process threshold value is meant and passes through threshold value from the top down, in other words, promptly be lower than this threshold value.Therefore when coefficient of friction is too low, reduces volume or close audio frequency apparatus fully according to embodiments of the present invention, so that the driver can more focus mostly on attentiveness on the road traffic.
According to embodiments of the present invention, described method can also possess the following step: reduce the numerical value that follow-up continuous detection characterizes the physical parameter of motor racing in volume; This numerical value and second threshold value of presetting are compared; And when detected numerical value along with first party during in the opposite direction through default second threshold value, volume reset to initial value or reopen.
In embodiments of the present invention, not only realized reducing automatically volume or closed audio frequency apparatus, and the situation that requires to improve attentiveness in the past after, audio frequency apparatus is reset on the numerical value before volume reduces again.At this, dangerous situation maybe needs the feature of the end of the situation of focusing one's attention on to be, along with first party in the opposite direction through the second default threshold value.If be lower than the second default threshold value, then volume is resetted when surpassing its such threshold value that then shows dangerous situation when this second threshold value is one, vice versa.Here first threshold can equate with second threshold value or be unequal.
The step that reduces volume also can comprise volume is reduced to zero or be reduced to the numerical value or the coefficient that can be provided with by the user.Audio frequency apparatus is different with closing fully, and volume is adjusted to zero can not stop the music playback, and only be switch to quiet.In comfortable especially execution mode, can determine in unsafe condition, whether will close audio frequency apparatus or only reduce volume by the user.Because the individual is to the impression difference of volume, so preferably also can be default by the user for the audio volume level of unsafe condition.
According to a kind of special execution mode, also can define a plurality of threshold values for same physical parameter, wherein, give the audio volume level of each threshold value configuration oneself.For example can be in the scope of first low speed or acceleration listen to news program or music program recording with normal (or manually being provided with) volume by the user.If speed or acceleration surpass presetting first threshold, then volume is reduced to certain numerical value.When if speed or acceleration also continue to increase then, then volume reduces again or closes audio frequency apparatus automatically.
In addition, at least one in the preset threshold value can be changed by the user.Therefore more strengthen changeability and its user's friendly of described method.For example can make corresponding threshold value be adapted to corresponding driver's personality and knowledge individually by this design.For example threshold value can be set like this, make and for example when relatively low speed, just pass through this threshold value quickly for the fresh driver.According to favourable design, for different drivers can storage threshold setting and/or corresponding audio volume level.
In order further to strengthen security performance, in the execution mode of described method, detect a plurality of sign motor racings physical parameter numerical value and compare with each physical parameter respective threshold separately, wherein, when at least one detected numerical value during through default respective threshold, is then carried out the step that reduces the audio frequency apparatus volume along first direction.In other words, in this design, monitoring more is used for the index of unsafe condition, wherein, exists the index threshold value of a physical parameter (=through) just to be enough to import the measure about the audio frequency apparatus volume of stipulating for unsafe condition.In this way simultaneously can consider multiple multi-form unsafe condition.
The execution mode of the method for the aforesaid audio frequency apparatus volume that is used for regulating automobile can store storage medium into the form of computer program, and this computer program causes the execution of each method step.Described method can be integrated in the existing system by this way easily.Storage medium can be the memory of any form known, compact disk read-only memory (CD-ROM) for example, hard disk, storage card etc.
The present invention also relates to be used for regulate the adjusting device of the audio frequency apparatus volume of automobile, this adjusting device has microprocessor, and this microprocessor is designed to: connect with vehicle-mounted audio device on the other hand with sensor device on the one hand; And be designed to: receive sensor signal about the physical parameter that characterizes motor racing, the sensor signal that receives and the predetermined threshold value of physical parameter are compared, and when the sensor signal that receives along first direction when the preset threshold value, output reduces the audio frequency apparatus volume or closes the signal of audio frequency apparatus.
Described adjusting device can be integrated in the existing automobile by this way.Only need have at least one transducer at automotive interior, it comprises the physical parameter that characterizes motor racing for this reason.This transducer just was present in the automobile mostly originally, therefore can dually utilize existing sensor device.What belong to this situation for example is to be equipped with braking or driving dynamics control system for example in the automobile of ABS (anti-lock braking system), ASR (Driving Antiskid Control System) or ESP (Electronic Stability Program (ESP)).
