It is known in the prior art to integrate a specific number of sound elements (loudspeakers) in a vehicle seat. For example, it is known to arrange loudspeakers in a matrix, for example a 6 by 4 matrix. The sound elements are manipulated in sound signals synchronously and independently of external boundary conditions. The loudspeakers are controlled in their entirety and are independent of the shape of the vehicle occupant sitting in the vehicle seat. But thereby produces undesirable sound because the distance of the ear from the speaker varies due to different body dimensions. If the speaker is covered or can vibrate freely, the sound played also changes.
A seat cushion with an acoustic device for a vibrating experience is known from the document KR 20,120,035,095A. The seat here comprises a five-speaker kit, comprising two lateral midrange speakers, a central woofer and two shoulder tweeters. The amplifier is mounted above the seat. The invention should provide a lower sound experience.
A sound management technique for a vehicle is known from document US 8 189 825 B2. An apparatus for controlling audio reception by a vehicle occupant is disclosed. The device is based on a monitoring system (camera) which determines whether the occupant is located in the seat and its position. The system adjusts the sound at each particular location.
An acoustically constructed seat with a vibration system for inducing bone conduction is known from document US 7 722,116 B2. The seat comprises three speakers, namely two tweeters at the shoulders and one central woofer.
A method for controlling an acoustic system in a vehicle is known from DE 10 308 B4. The method is based on an interior space recognition system (camera) for determining the head position of the occupant. Depending on this position, the acoustic system is subjected to an optimized automatic adjustment, which is adapted to the sitting position (sitzprofile) of the occupant.
Disclosure of Invention
It is therefore an object of the present invention to provide a sound system and a method for controlling a sound system, which individually controls a loudspeaker for a vehicle occupant in a vehicle seat.
This object is achieved by a sound system according to claim 1 and by a method for controlling a sound system according to claim 10. The improvements and advantageous embodiments are part of the dependent claims. Additional advantages and features result from the description of the general description and the description of the embodiments.
The subject of the invention is a sound system for a vehicle seat, wherein the sound system comprises at least one loudspeaker, at least one interior space camera and at least one sensor, wherein the at least one loudspeaker and the at least one sensor are arranged in the vehicle seat.
According to the invention, the sound system is designed for controlling at least one loudspeaker in dependence on the build of the vehicle occupant detected by the interior camera.
The loudspeakers are typically arranged in a 6 by 4 matrix. Alternatively, the speakers can be arranged variably and asymmetrically. Typically, the sound system comprises at least two loudspeakers, which can be arranged in correspondence with the prevailing space conditions. The arrangement of the speakers in the x-direction and the y-direction in the vehicle seat can be made and varied asymmetrically. In general, the at least one loudspeaker is arranged below the seat cover as close as possible thereto. Alternatively, the at least one speaker may be arranged in a headrest of the vehicle seat or in an armrest of the vehicle seat.
The interior space camera is typically designed to transmit an image of the vehicle occupant to the sound system. Typically, the sound system is designed for determining the contact area of the vehicle occupant on the vehicle seat on the basis of the transmitted vehicle occupant image. The sound system is designed for actuating the loudspeaker in response to the determined contact area. The contact region is here a region of the vehicle seat in which the vehicle occupant is in contact with the vehicle seat. In particular, the contact region is formed here in the region of the backrest of the vehicle seat. Alternatively, the interior camera may be designed for transmitting real-time images to a sound system, wherein the sound system is designed for controlling the speakers in correspondence to the body shape of the vehicle occupant, which is transmitted in real-time.
In an alternative embodiment, the seat surface of the vehicle seat can likewise be part of the contact area. The interior camera is thus designed for capturing an image of the body shape of the vehicle occupant and transmitting the image to the sound system. The sound system is designed for detecting the build of the vehicle occupant on the basis of the transmitted image and for determining the abutment region on the basis of the build of the vehicle occupant.
In a design, the sound system is designed for controlling the at least one loudspeaker as a function of a seating position (Sitzposition) of the vehicle occupant detected by the at least one sensor. Typically, at least two sensors are arranged in each vehicle seat. Typically, at least two sensors are arranged in the region of the backrest of one respective vehicle seat of the vehicle. At least one sensor is designed for transmitting the detected seating position of the vehicle occupant to the sound system. The sound system is designed for determining an abutment area of the vehicle occupant on the basis of the transmitted seating position.
In a further embodiment, the sound system comprises a communication interface which is designed for receiving and evaluating image data of the interior camera and/or data of the at least one sensor, wherein the sound system is designed for controlling the at least one loudspeaker of the sound system on the basis of the image data of the interior camera and/or the data of the at least one sensor. The communication interface is typically designed to be unidirectional.
In an alternative embodiment, the communication interface is designed to be bi-directional. The communication interface is designed for receiving image data of the interior space camera and/or data of the at least one sensor. In general, the sound system comprises an evaluation unit which is designed to determine an abutment region of the vehicle occupant on the vehicle seat on the basis of the transmitted image data of the interior camera and the data of the at least one sensor, wherein the sound system is designed to operate the speakers of the sound system on the basis of the determined abutment region. In general, sound systems are designed for loudspeakers arranged in an abutment area to be steered separately from loudspeakers arranged outside the abutment area.
In a further embodiment, the sound system is designed to determine an abutment region of the vehicle occupant on the vehicle seat on the basis of the detected body shape and/or the seating position of the vehicle occupant and to control the at least one loudspeaker as a function of the abutment region. In general, sound systems are designed for determining an abutment region using the build of a vehicle occupant detected by an interior space camera and the seating position detected by at least one sensor. This makes it possible to distinguish between the rest and non-rest areas of the vehicle seat as accurately as possible, so that the loudspeakers can be controlled particularly accurately.
In a further embodiment, the sound system is designed for automatically actuating the at least one loudspeaker when the contact area changes. In general, sound systems are designed for automatically actuating at least one loudspeaker in response to a change in the seating position or in the contact area of a vehicle occupant as the seating position of the vehicle occupant and the contact area of the vehicle occupant on the vehicle seat change accordingly.
In a development of the invention, the sound system is designed for outputting mid-frequency and high-frequency sound without at least one loudspeaker in the region of the contact region of the vehicle occupant on the vehicle seat. By stopping the output of the mid-frequency and high-frequency sounds in the abutment region of the vehicle occupant on the vehicle seat, the sound quality in the vehicle interior space is improved because the mid-frequency and high-frequency sounds are not attenuated by the body shape of the vehicle occupant. Typically, mid-frequency and high-frequency sounds are output through at least one speaker located outside the area of abutment. This facilitates free, undisturbed propagation of medium and high frequency sounds.
In a further development, the sound system is designed for outputting low-frequency sound via at least one loudspeaker in the contact region of the vehicle occupant. Outputting low-frequency sound through a speaker in an abutment region of a vehicle occupant provides the following advantages: the vehicle occupant can perceive the low-frequency sound as a bass portion through the body. In contrast, outputting mid-frequency and high-frequency sounds in the abutment region of the vehicle occupant causes sound distortion and is detrimental to the sound experience of the vehicle occupant.
In one refinement, the at least one sensor is designed to detect a seat state/seat position (sitzshellung) of the vehicle seat. In general, sound systems are designed for adjusting the sound intensity based on the seat state of a vehicle seat, for example in a seat state in the horizontal direction.
In a further embodiment, the sound system is designed for actuating the at least one loudspeaker as a function of the detected seat state of the vehicle seat. Alternatively, the seating state of the vehicle seat may be used to determine the area of abutment of the vehicle occupant on the vehicle seat. This provides the following advantages: additional parameters may also be used for determining the contact area of the vehicle occupant on the vehicle seat.
In a design, the sound system can be combined with an automatically controllable massage system and/or a light system. Alternatively, the sound system can be manipulated in opposition to the massage system and/or the light system. Thus, the sound system may be configured as part of a mixing system.
The invention also relates to a method for controlling a sound system in a vehicle comprising the aforementioned sound system.
In a first step, an interior space camera detects the body shape of a vehicle occupant. Typically, the interior space camera detects at least one image. The interior camera is generally designed for transmitting at least one detected image as image data. The communication interface of the sound system receives image data transmitted through the interior space camera. The communication interface is designed for transmitting the received image data to an evaluation unit of the sound system.
In another step, at least one sensor detects a seating position of a vehicle occupant. The at least one sensor typically transmits the detected seating position of the vehicle occupant to the sound system. The communication interface of the sound system receives data regarding the seating position transmitted through the sensor. The communication interface transmits data about the seating position to an evaluation unit of the sound system. Advantageously, at least two sensors detect the seating position of a vehicle occupant in or on the vehicle seat.
In a further step, an abutment region of the vehicle occupant on the vehicle seat is determined on the basis of the seating position and/or the build of the vehicle occupant. An evaluation unit of the sound system determines an abutment region of the vehicle occupant on the vehicle seat from the received image data of the interior camera with respect to the body shape. The evaluation unit of the sound system also determines the contact area of the vehicle occupant on the vehicle seat from the received data of the sensor about the seating position. By using the image data of the interior camera and the data of the sensor about the sitting position, the contact area of the vehicle occupant on the vehicle seat can be determined particularly accurately.
In a further step, the loudspeaker is operated as a function of the abutment area. The contact area of the vehicle occupant on or at the vehicle seat is determined on the basis of image data recorded by the interior space camera with respect to the body shape of the vehicle occupant and/or on the basis of the seating position of the vehicle occupant on the vehicle seat detected by the at least one sensor and/or on the basis of the seat state of the vehicle seat.
Based on the determined abutment area, speakers are categorized into speakers located within the abutment area and speakers located outside the abutment area. The sound system operates in a different manner for loudspeakers located outside the abutment area than for loudspeakers located inside the abutment area. Thus, the sound system operates speakers located in the abutment region with low frequency sound, while the sound system operates speakers located outside the abutment region with medium and high frequency sound.
