An apparatus for modifying sound audibilized from an audio component in a vehicle comprising a processor connected to the audio component and for controlling the operation thereof. A sensor is connected to a gear box of the vehicle for sensing a position of a gear in the vehicle and further connected to the processor. The sensor senses the position of the gear and determines if the gear is in one of a first position or a second position and causes the processor to modify the audibilized sound based on the determination from a first sound level to a second sound level.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a vehicular safety device, and more specifically, to a reverse gear volume reducer. A sensor is connected to the gearshift of the vehicle for sensing the position of the gearshift. A cutoff switch is automatically actuated when the sensor senses the gearshift of a vehicle is in the reverse position. Actuation of the cutoff switch results in the volume of the vehicular audio components being at least one of decreased to a predetermined level and cutoff. The decrease or cessation in audio component volume can prevent accidents by reducing the distractions to the driver when reversing and increasing the driver&#39;s ability to hear outside sounds.

     A vehicle safety system for detecting the presence of objects in the vicinity of the vehicle and for producing an indication upon the detection of the objects. The system comprises a front sensor and rear sensor each of which includes a Doppler radar and side sensors which include proximity radars. The system also includes a vehicle velocity sensor which senses the velocity of the vehicle and produces an output indicative thereof. A signal processing unit receives the outputs of the front and rear sensors and the vehicle velocity sensor and produces an output which is indicative of the vehicle&#39;s capability of stopping prior to colliding with an object detected in front of the vehicle, and also produces an output indicative of the range and closing speed of an object detected to the rear of the vehicle. An indicator is coupled to the signal processing unit and produces a signal indicative of the signal processor output, and signals indicative of the location of an object alongside the vehicle. The output of the processing unit may also be applied to the vehicle brake and accelerator controls for slowing down the vehicle if the operator does not respond properly to a warning signal generated by the indicator.

     A vehicular back-up lamp alarm device, comprising a sonic element, such as a buzzer, which is an integral part of the lamp base or of socket for receiving it. The sonic element is connected so it will be in parallel with the back-up lamp. Alternatively, the sonic element may be an integral part of a socket converter having a conventional lamp base and socket, and connected in parallel with the electrical connections between such base and socket. As a result, the operating voltage which is applied to the back-up lamp when the vehicle is put into reverse gear will also cause the sonic element to emit an audible alarm.

     A method and device prevents damage to a vehicle approaching an obstacle, such as, for example, a loading ramp, while traveling in reverse. When a vehicle, particularly a vehicle train consisting of a towing vehicle and a trailer or semi-trailer, approaches an obstacle in reverse travel, there exists the possibility that the vehicle may impact the obstacle as a result of an erroneous estimation or inappropriate driving maneuver, potentially resulting in damage to the vehicle and/or to the obstacle. This problem occurs with relative frequency, particularly when approaching a loading ramp. In accordance with the invention, the driver of the vehicle is assisted during reverse travel such that damage due to excessive impact is automatically avoided, independently of the driver&#39;s actions. A distance sensor is installed on the vehicle, near the tail, which transmits a signal representative of the distance from an obstacle to an electronic control device. The electronic control device evaluates the distance value measured by the distance sensor and adapts the speed of the vehicle during reverse travel in accordance with a predetermined algorithm in such manner that the approach to the obstacle takes place without damage to the vehicle and/or the obstacle. The control device advantageously influences the braking system of the vehicle and, if necessary, the drive engine, in a suitable manner.

     A reversing alarm for a vehicle emits an audible signal in the form of pulses of broad band sound when the vehicle is put into reverse gear. The broad band sound allows persons in the vicinity to locate the vehicle, as the human brain is able to process broad band sound to pinpoint the location of the sound source in a way which is not possible with single tone sounds. The alarm is implemented via a simple electronic circuit which uses a zener diode as a signal generator  20  to generate the broad band sound.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following discussion describes in detail one embodiment of the invention and several variations of that embodiment. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims. 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,  FIGS. 1 through 9  illustrate a volume reducing mechanism of the present invention which is indicated generally by the reference numeral  10 . 
       FIG. 1  is a perspective view of the volume reducing mechanism  10  of the present invention. The volume reducing mechanism  10  includes a gear shift sensor  34 , not shown, to determine the current status of the gearshift of a vehicle  18 , shown in  FIG. 2 . The volume reducing mechanism  10  further includes a gearshift  12  for selecting the gear in which the car is operating. The gearshift  12  includes a handle  28  and a gear indicator panel  30 . The gear indicator panel  30  includes a plurality of markings  32  typically found thereon for indicating the gear status of the vehicle  18 . The markings  32  include a “P” corresponding to “park,” an “R” corresponding to “reverse,” an “N” corresponding to “neutral,” and at least one marking to indicate “drive,” shown herein by a “D.” The handle  28 , as is typical of gearshift handles  28 , shifts between the gears of the vehicle  18 . As shown herein, the handle  28  is displaced adjacent to the “R” indicating the vehicle  18  is in the “reverse” gear. 
     The volume reducing mechanism  10  of the present invention is advantageous in that makes vehicular  18  operation safer. The gearshift sensor  34 , as shown in  FIG. 4 , senses the current position of the gear of the vehicle. When the gearshift  12  is in the R position as shown herein, if an audio component  16  is audibilizing content, the volume of the audio component  16  is reduced to a specified level. Reducing the volume of the audio component  16  when the vehicle  18  is sensed to be in “reverse” allows a user  14  to focus on driving the car in reverse. Increasing the user&#39;s  14  focus on driving in reverse increases the likelihood that it will be done safely by improving the driver&#39;s attention to details in the surrounding area. The present invention  10  allows for the volume of the audio component to be selectively increased when the gear of the vehicle  18  is sensed to be in at least one of “park”, “drive” and “neutral”. 
       FIG. 2  is an illustrative view of the volume reducing mechanism  10  of the present invention. The volume reducing mechanism  10  includes the gear shift sensor  34 , not shown, to determine the current gear status of the vehicle  18 . The volume reducing mechanism  10  further includes the gearshift  12 . The gearshift  12  includes the handle  28  and the gear indicator panel  30 . The plurality of markings  32  typically found on the gear indicator panel  30  are located thereon for indicating the gear status of the vehicle  18 . The markings  32  include the “P” corresponding to “park,” the “R” corresponding to “reverse,” the “N” corresponding to “neutral,” and at least one marking to indicate “drive,” shown herein by a “D.” The handle  28 , as is typical of gearshift handles  28 , shifts between the gears of the vehicle  18 . 
     The user  14  is in the vehicle  18 . As shown herein, an indicator arrow  36  shows that the handle  28  of the gearshift  12  is adjacent to D 1  on the gear indicator panel  30  and thus the vehicle  18  is in drive. When the sensor  34  senses that the gear of the vehicle  18  is one of P, N, or D, the audio component  16  is permitted to audibilize a sound  20  from at least one output device such as speakers, described herein as music, at a level selected by the user  14 . This music  20  is shown as plurality of musical notes and is shown for purposes of example only, and any number of sounds may be broadcast from the audio component  16 . 
       FIG. 3  is an illustrative view of the volume reducing mechanism  10  of the present invention. The volume reducing mechanism  10  includes the gear shift sensor  34 , not shown, to determine the current gear status of the vehicle  18 . The volume reducing mechanism  10  further includes the gearshift  12 . The gearshift  12  includes the handle  28  and the gear indicator panel  30 . The plurality of markings  32  typically found on the gear indicator panel  30  are located thereon for indicating the gear status of the vehicle  18 . The markings  32  include the “P” corresponding to “park,” the “R” corresponding to “reverse,” the “N” corresponding to “neutral,” and at least one marking to indicate “drive,” shown herein by a “D 1 .” The handle  28 , as is typical of gearshift handles  28 , shifts the gears of the vehicle  18 . 
     The user is in the vehicle  18 . As shown herein, the indicator arrow  36  shows that the handle  28  of the gearshift  12  is adjacent to R on the gear indicator panel  30  and thus the vehicle  18  is in reverse. The sensor  34  sensed the gearshift  12  moving from D 1 , in  FIG. 2 , for example, to R, shown herein. In response to the gearshift  12  moving to R, the sensor  34  causes the volume of the audio component  16  to one of cease or to lower by a predetermined level. 
     The gearshift sensor  34  also senses when the gearshift  12  returns to one of P-park, N-neutral, or D-drive. When the gearshift  12  has returned to one of P-park, N-neutral, or D-drive for more than a predetermined amount of time while the car is still on, the volume of the audio component  16  gradually returns to the level of volume before the gear status was that of R-reverse. 
       FIG. 4  is a block diagram of the gear shift of the volume reducing mechanism  10  of the present invention. The volume reducing mechanism  10  includes the gear shift sensor  34 , a switch  38 , a processor  22  and the audio component  16 . The gear shift sensor  34  determines the position of the gears of the vehicle  18 , shown in  FIG. 2 . Shown herein, the sensor  34  senses that the gear of the vehicle  18  is in the drive position. When the vehicle  18  is in the drive position, the switch  38  is in a first open position. The switch  38  of the volume reducing mechanism  10  also operates in a similar fashion when the gear sensor  34  senses that the gears of the vehicle  18  is one of P-park position and N-neutral position. When the switch  38  is in the first open position, a user is able to control the processor  22  to operate the audio component in any desired manner. As shown herein, the audio component is in a first “on” position and is able to audibilize a sound at a user-selected volume level to be output by at least one output device (not shown). 
     When the gear shift sensor  34  senses that the vehicle  18  is in engaged in the reverse position, the sensors causes the switch  38  to move from the first open position to a second closed position. When the switch  38  is in the second closed position, the processor  22  causes the audio component  16  to move from the first “on” position to a second “off” position. When the audio component  16  is caused to be in the second “off” position, the audio component  16  at least one of ceases to audibilize the selected sound at the user-selected volume and reduces the sound currently being audibilized by the audio component to a predetermined level which is lower than the user-selected volume level. Ceasing to audibilize the sound or at least lowering the volume to a predetermined lower level when the vehicle  18  is driving in reverse, makes vehicular  18  operation safer. This action allows the user  14  to focus their entire attention to the activity of driving the vehicle in reverse and allows the user to concentrate on any objects or persons in the vicinity of the vehicle  18 . Increasing the user&#39;s  14  focus on these objects and details increases the likelihood that the driver will avoid these objects and decreases the amount of mishaps caused by inadequate level of attention being paid while driving a vehicle in reverse while backing up. 
     Additionally, when the sensor  34  senses that the gear of the vehicle is moving from the second reverse position to the first drive, park, or neutral position, the sensor causes the switch  38  to move back into the first open position from the second closed position. Additionally, the sensor  34  is able to detect that the vehicle gear is being re-engaged from the reverse position to any of the park, neutral or drive position. When the sensor  34  senses this re-engagement, the sensor  34  signals the processor  22  of this action. Thus, when the switch  38  returns to the open position, the processor  22  causes the audio component  16  to move back into the first “on” position. Upon returning to the first “on” position, the volume at which the sound is audibilized by the audio component  16  increases gradually over a predetermined amount of time from either a zero-level or a reduced level until the sound being audibilized thereby is at the user-selected volume. Preferably, the predetermined amount of time ranges between substantially 3 seconds and substantially 10 seconds, and more preferably is equal to substantially 5 seconds. 
       FIG. 5  is a flow diagram of the volume reducing mechanism  10  of the present invention. In step S 100 , the audio component is operating to audibilize sound from at least one output device at a user-selected volume. While in step S 100 , the vehicle may be engaged in one of park, neutral or drive. The gear shift is then moved into the reverse position in step S 102 . In step S 104 , the audio component volume is automatically turned off. Alternatively, step S 104  can include reducing the volume of the audio component to a level less than the user-selected volume level. The result of steps S 102  and S 104  is reducing any ancillary distraction to the driver thereby allowing the driver to more safely maneuver the car in reverse and pay increased attention to objects in the vicinity of the vehicle. 
     Upon the driver determining that driving in reverse is no longer necessary, the driver causes the gear shift to moved into one of drive, park or neutral in step S 1106 . After the gear shift is moved back into one of drive, park or neutral in step S 106 , in step S 108  the audio component is caused to audibilize sound at the user-selected volume as output in step S 1100 . 
       FIG. 6  is a flow diagram of an alternate embodiment of the volume reducing mechanism  10  of the present invention. In step S 200 , the audio component is operating to audibilize sound from at least one output device at a user-selected volume. While in step S 200 , the vehicle may be engaged in one of park, neutral or drive. The gear shift is then moved into the reverse position in step S 202 . In step S 204 , the audio component volume is reduced to a predetermine level that is lower than the user-selected volume level. The result of steps S 202  and S 204  is reducing any ancillary distraction to the driver thereby allowing the driver to more safely maneuver the car in reverse and pay increased attention to objects in the vicinity of the vehicle. 
     Upon the driver determining that driving in reverse is no longer necessary, the driver causes the gear shift to moved into one of drive, park or neutral in step S 206 . After the gear shift is moved back into one of drive, park or neutral in step S 206 , in step S 208  the audio component is caused to gradually increase the volume of the sound being audibilized until the sound is being audibilized at the user-selected volume as output in step S 200 . The gradual increase of the volume occurs over a predetermined amount of time, preferably equal to substantially 5 seconds. 
       FIG. 7  is an illustrative view of the prior art that led to the volume reducing mechanism  10  of the present invention. Shown herein, the user  14  is in the vehicle  18  and listening to music  20  from the audio component  16 . A child  24  has lost control of a ball which has rolled behind the vehicle  18 . The user  14  has used the handle  28  to change the gears and put the vehicle  18  in reverse as indicated by the illuminated reverse lights  25 . However, because the music  20  is still playing and the driver is unable to react to the verbal request made by the child  24  telling the driver to stop so that the ball may be retrieved. In addition, the music  20  playing at a loud volume is also distracting to the user  14 , preventing him  14  from being more cautious while reversing the vehicle  18 . Thus, it is desirable to have the volume reducing mechanism of the present invention as described hereinabove with respect to  FIGS. 1-6  and hereinafter with respect to  FIGS. 8 and 9 . 
     The volume reducing mechanism  10  of the present invention makes operation of a vehicle  18  safer. The audio component  16  can output music  20  at the user  14  desired level while the vehicle is in engaged in one of drive, park, or neutral. However, when the user  14  changes the gear of the vehicle  18  to reverse, the music  20  is one of lowered to a predetermined level of stopped completely. In this way, the user&#39;s  14  attention is focused on the activity of reversing the vehicle  18 , as opposed to listening to the audio component  16 . When the focus is on reversing, the user  14  would be able to hear the child  24  telling him  14  to stop the vehicle from continuing in a reverse direction. 
       FIG. 8  is an illustrative view of an alternative embodiment of the volume reducing mechanism  10  of the present invention. The volume reducing mechanism  10  includes the gear shift sensor  34  for sensing the gear in which the vehicle  18  is currently engaged. However, this embodiment of the mechanism  10  of the present invention includes a connection between the sensor  34  and the operation of cellular telephone electronics. Cellular telephone use while driving has increased and it is desirable to have a mechanism to adjust or eliminate the volume being output by the cellular telephone speaker when the driver needs to maneuver the vehicle in reverse. 
     The user  14  is in the vehicle  18  and is operating the vehicle  18  in drive as indicated by the indicator arrow  36  which shows that the handle  28  of the gearshift  12  is adjacent to D 1  on the gear indicator panel  30 . When the sensor  34  senses that the gear of the vehicle  18  is one of P, N, or D, the sound of the cellular speaker is able to be output at the user-selected level. As shown herein, the sound is audibilized by a cellular head-set typically required as part of a hands-free kit. As shown herein, the cellular telephone is operating in a traditional manner and the user is able to selectively communicate using the phone. 
       FIG. 9  is an illustrative view of the volume reducing mechanism  10  of the present invention. Shown herein is the volume reducing mechanism  10  connected to the cellular phone  26  engaged to selectively reduce the volume of the output speaker or to eliminate the sound from being output thereby. 
     The user is in the vehicle  18  and the indicator arrow  36  shows that the handle  28  of the gearshift  12  is adjacent to R on the gear indicator panel  30  and thus indicating that the vehicle  18  is in reverse. The sensor  34  sensed the gearshift  12  moving from D 1 , in  FIG. 2 , for example, to R, shown herein. In response to the gearshift  12  moving to R, the sensor  34  causes the volume of the cellular phone  26  to one of cease or to be lowered to a predetermined level. Shown herein, the volume has ceased. This grants the driver  14  greater focus while operating the vehicle  18  in reverse. 
     The gearshift sensor  34  also senses when the gearshift  12  returns to one of P-park, N-neutral, or D-drive. When the gearshift  12  has returned to one of P-park, N-neutral, or D-drive for more than a predetermined amount of time while the car is still on, the volume gradually returns to the level of volume before the vehicle  18  was put in R-reverse. 
     The device described hereinabove is intended to be formed integral with newly produced vehicles as well be formed as an add-on device to retro-fit previously produced vehicles. The device is able to work to reduce the volume of a plurality of audio components that are useable in a vehicle. These components include but are not limited to a radio, a CD player, a DVD player, a cassette player, a bi-directional communication device such as a cellular telephone, and an externally connectable electronic audio component such as a portable digital music player. 
     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of devices differing from the type described above. 
     While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. 
     Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
