FIELD OF THE INVENTION 
     The present invention relates to a vehicle safety system, more specifically but not by way of limitation, a vehicle safety system that monitors the distance intermediate the vehicle in which the safety system is installed and all proximate vehicles and/or objects wherein the system provides visual and audio notification of objects and/or other vehicles that may be in a position to create a potentially dangerous situation. 
     BACKGROUND 
     Millions of individual utilize vehicles such as but not limited to passenger automobiles as part of their daily routine. Whether driving to work or to another destination, daily utilization of a vehicle is common. With the plurality of vehicle on the roads, thousands of accidents occur everyday and hundred of lives are lost each week in automobile accidents. While safety device such as but not limited to seat belts and air bags routinely save lives, these safety features are unable to prevent automobile accidents. 
     Distracted driving is one of the main causes of automobile accidents. Whether the driver is adjusting the radio or air conditioning system, talking on a cellular phone or engaged in a conversation with another individual within the automobile, drivers of automobiles have a plurality of sources of distractions, which lead to numerous accidents. One of the leading causes of accidents are drivers that follow to close behind another automobile while traveling in the same direction along a road. The lack of proper distance between the two vehicles results in the driver being unable to have the proper time or distance to react to avoid a collision with the vehicle to which they are following too close. Distracted driving often results in drivers following too close and results in the inability for the driver to react in time to a situation and results in an accident that can often be fatal. 
     One problem with current safety systems is that they fail to measure the distance between two vehicles and provide notification as to whether or not the driver operating a vehicle that is following another vehicle is following at a proper distance so as to provide sufficient time and distance for the driver to significantly increase the probability of avoiding a collision. Additionally, the vehicle that is being followed too close does not have the ability to provide a signal to a vehicle behind it alerting the driver of the vehicle that they are following to closely and should alter their position in order to avoid a potential collision. 
     Accordingly there is a need for a vehicle safety system that monitors the distance between vehicles and provide notification to the drivers of the vehicles as to whether or not their vehicles are properly positioned so as to substantially increase the probability of colliding with each other. 
     SUMMARY OF THE INVENTION 
     It is the object of the present invention to provide a safety system mounted within at least one vehicle that monitors the distance between the vehicle and other vehicles traveling proximate thereto wherein the system alerts the driver of the vehicle as to whether or not their vehicle is properly spaced relative to the other vehicles on the road so as to substantially increase the probability of avoiding a collision with the vehicles proximate to the vehicle equipped with the safety system. 
     Another object of the present invention is to provide a safety system for a vehicle that measures the distance between a first vehicle and a second vehicle wherein the first vehicle having the safety system installed therein provide visual and audio notification to the driver information to substantially increase the probability of colliding with another object or vehicle. 
     Yet a further object of the present invention is to provide a safety system installed in a first vehicle that is capable of detecting the presence of either an object or a second vehicle within a defined perimeter of the first vehicle and provide visual and/or audio notification thereof to the driver of the first vehicle. 
     Still another object of the present invention is to provide a safety system installed in a first vehicle that measures the distance between the first vehicle and a second vehicle wherein the system provides a visual signal to the driver of the second vehicle that the second vehicle is too close to the first vehicle. 
     An additional object of the present invention is to provide a safety system installed within a vehicle that detects objects or a second vehicle within a defined perimeter of the vehicle that is operably coupled to the braking system of the vehicle. 
     Yet another object of the present invention is to provide a safety system installed within a vehicle that includes a database having a roadmap the has stored therein the locations of intersections having traffic signs such as but not limited to stop signs or traffic signal wherein the safety system is operable to provide notification to the driver upon being proximate the intersection. 
     A further object of the present invention is to provide a safety system installed within a vehicle that includes a light that flashes in a particular sequence so as to notify a driver of a second vehicle behind and following the vehicle with the safety system installed therein that the second vehicle is too close. 
     To the accomplishment of the above and related objects the present invention may be embodied in the form illustrated in the accompanying drawings.

     DETAILED DESCRIPTION 
     Referring now to the drawings submitted herewith, wherein various elements depicted therein are not necessarily drawn to scale and wherein through the views and figures like elements are referenced with identical reference numerals, there is illustrated vehicle safety system 100  constructed according to the principles of the present invention. 
     The vehicle safety system  100  includes a controller  10  mounted within the vehicle  5 , which functions to control the operational tasks of the vehicle safety system  100 . The controller  10  includes the necessary electronics to receive, store, manipulate and transmit data signals required for various operations of the vehicle safety system  100 . The controller  10  is electrically coupled with the vehicle&#39;s twelve-volt power system and is configured to provide power to the components of vehicle safety system  100 . 
     Operably coupled to the controller  10  are a plurality of transceivers  20 . The transceivers  20  function to monitor the perimeter of the vehicle  5  for objects such as but not limited to other vehicles or obstacles. The transceivers  20  continuously monitor the perimeter of the vehicle  5  and transmit data back to the controller  10  wherein the controller  10  executes algorithms that constantly monitor the position of objects within the perimeter of the vehicle  5  and the distance intermediate the vehicle  5  and the detected objects. While no particular perimeter distance is required, good results have been achieved utilizing transceivers  20  that are programmed to provide monitoring capabilities for approximately a half-mile from either the front or rear of the vehicle and approximately thirty yards for either the left and right side of the vehicle. The transceivers  20  utilize laser light and transmit the laser light to provide monitoring of objects within the defined perimeter of the vehicle  5 . As is known in the art, laser light sensors utilize laser light and project the laser light and subsequent contact with an object, a portion of the light is reflect back to the transmission source. The transceivers  20  transmit the laser light and further function to receive any reflected light from the transmission. The transceivers  20  are operated by the controller  10  wherein the controller  10  functions to execute the continuous transmission of the laser light and record the time for any reflection that may occur. The controller  10  converts the time into a distance and monitors the distance between the vehicle  5  and the detected objected. While good results have been achieved utilizing laser light for the transceivers  20 , it is contemplated within the scope of the present invention that the transceivers  20  could utilize radar and/or sonar to monitor the perimeter of the vehicle  5 . 
     The vehicle safety system  100  further includes a global positioning receiver  30 . The global positioning receiver  30  is a conventional global positioning receiver that utilizes trilateration to calculate its position on the earth&#39;s surface. The global positioning receiver  30  is operably coupled to the controller  10  that includes a roadmap database. The controller  10  utilizes the information from the global positioning receiver  30  and the roadmap database to identify the exact location of the vehicle  5 . The vehicle safety system  100  functions to alert the driver of the vehicle  5  when approaching an intersection that has either a traffic signal or some other traffic sign that would require the vehicle  5  to either yield or stop. The controller  10  continuously receives data from the global positioning receiver  30  and utilizes the positioning data and integrates the positioning data with the roadmap database. The roadmap database includes therein all location information pertaining to traffic signals and/or traffic signs. As the driver of the vehicle  5  approaches an intersection or other area of the road that the roadmap database has data identifying the area as having a traffic signal or other sign that could result in the driver of the vehicle  5  to either stop or alter their current speed, the vehicle safety system  100  provides a visual warning signal to the driver of the vehicle  5  utilizing the monitor  40 . It is contemplated within the scope of the present invention that any type of visual signal could be provide to the driver utilizing the monitor  40  such as but not limited to a specific indicia or logo being illuminated in the center region  41  of the monitor  40 . 
     The vehicle safety system  100  further includes a brake actuator  50 . The brake actuator  50  further includes a piston  52 , rod  54  and keeper  56 . The piston  52  is a conventional hydraulically operated piston that is operably coupled to the rod  54 . The rod  54  is an elongated bar constructed of s substantially rigid material such as but not limited to metal. Integrally secured to the second end  57  of the rod  54  is the keeper  56 . The brake actuator  50  is operably coupled to the controller  10  and receives a signal therefrom to engage upon certain criteria being fulfilled. For example but not by way of limitation, as the vehicle  5  is traveling down a road and the transceivers  20  detect an object in the path of the vehicle  5 , the controller  10  continuously calculates the distance between the vehicle  5  and the detected object. If the controller  10  calculates that the distance between the vehicle  5  and the detected object has reached a certain distance that upon continuance thereof the vehicle  5  would collide with the object the controller  10  will transmit a signal to the brake actuator  50  to begin applying the brake  59  of the vehicle  5  so as to either reduce the speed or stop the vehicle in order to substantially increase the probability of the vehicle  5  colliding with the detected object. Upon receiving a signal from the controller  10 , the brake actuator  50  will activate the piston chamber  52  that will move the rod  54  towards the brake  59 . The keeper  56  is operable to releasably secure to the brake pedal lever  91 . While no particular method of releasably coupling is required between the keeper and the brake pedal lever  91 , good results have been achieved by utilizing an electromagnet to releasably secure the keeper  56  to the brake pedal lever  91 . Ensuing the keeper  56  releasably securing to the brake pedal lever  91 , the piston chamber  52  begins to retract the rod  54  towards the piston chamber  52  so as to engage the brake system  61  of the vehicle  5 . It is contemplated within the scope of the present invention that the vehicle safety system  100  could engage the brake system  61  of the vehicle  5  so as to increase the distance between the vehicle  5  and the detected object and maintain a proper distance therebetween or completely stop the vehicle  5  so as to substantially increase the probability of colliding with the detected object. If the controller  10  engages the brake system  61  of the vehicle  5  so as to reduce the speed of the vehicle and maintain a proper distance between the vehicle  5  and the detected object wherein the detected object is traveling in the same direction as the vehicle  5 , the controller  10  utilizes a programmed algorithm and data signals from the transceivers  20  to engage the brake system  61  until the vehicle  5  is within a proper distance as defined by the programmed algorithm within the controller  10 . Those skilled in the art will recognize that numerous distances could be programmed into the controller  10  as safe distances based upon the current speed of the vehicle  5 . 
     The vehicle safety system  100  further includes lateral transceivers  65  that monitor the presence of objects that are located on either side of the vehicle  5 . The lateral transceivers  65  function to detect and measure the presence of objects such as but not limited to another vehicle that are proximate either the left side or right side of the vehicle. The controller  10  is programmed to transmit a signal to the monitor  40  wherein the monitor displays a visual notification to the driver of the vehicle  5  as to the presence of an object on either the left side or right side of the vehicle  5 . While no particular visual notification is required, good results have been achieved by utilizing an illuminated letter R and an illuminated letter L displayed on the monitor  40 , so as to alert the driver of the vehicle  5  as to the presence of a detected object on the right side or left side respectively of the vehicle  5 . 
     The vehicle safety system  100  further includes a warning light  80  mounted proximate the rear window  81  of the vehicle  5 . The warning light  80  is operable to provide a visual signal to the driver of a second vehicle that is proximate the vehicle  5  wherein the visual signal is provided upon detection that the second vehicle proximate the vehicle  5  is too close. The warning light  80  is a conventional light that is either integrated into the brake light system of the vehicle or is mounted adjacent thereto. The warning light  80  is operably coupled to the controller  10  and the controller  10  transmits signals to the warning light  80  so as to execute the illumination thereof. It is contemplated within the scope of the present invention that the warning light  80  could illuminate in a sequence pattern based upon the calculated distance between the vehicle  5  and the second detected vehicle. More specifically but not by way of limitation, the warning light  80  could be programmed to flash three times sequentially and a fourth time for approximately five seconds to notify the driver of the second vehicle that the second vehicle is too close to the vehicle  5 . It is further contemplated within the scope of the present invention that the controller  10  utilizes preprogrammed distances from sources such as but not limited to the National Institute for Highway Safety in executing the algorithm and determining what distance should be measured between the vehicle  5  and the second vehicle so as to illuminate the warning light  80 . More specifically but not by way of limitation, the controller  10  is programmed to illuminate the warning light  80  to warn a second vehicle generally rear of the vehicle  5  if the second vehicle is closer to the vehicle  5  than two car lengths at twenty miles per hour, three car lengths at thirty miles per hour and four car lengths at forty miles per hour. Those skilled in the art will recognize that the speed to car length ratio could be measure to include numerous different speeds. While numerous colors could be utilized for the warning light  80 , good results have been achieved utilizing an amber colored light. It is further contemplated that the warning light  80  could utilize a second color in addition to amber to provide an illumination sequence to alert vehicles proximate to and generally behind the vehicle  5 . More specifically but not by way of limitation, the second color utilized could be red. 
     The warning light  80  is additionally activated with a particular illumination sequence when the vehicle safety system  100  is engaging the brake actuator  50  so as to alert drivers of additional vehicles proximate to the vehicle  5 . While any particular illumination sequence could be utilized, good results have been achieved utilizing an illumination sequence that alternates between the first color and second color five times, then flashes the second color three times. It is additionally contemplated within the scope of the present invention that subsequent the aforementioned sequence that the controller  10  would then activate the conventional hazard warning lights of the vehicle  5 . 
     The monitor  40  is integrally mounted within the dashboard  105  of the vehicle  5  and is a conventional LCD monitor. The monitor  40  further includes audio speakers (not illustrated herein). The vehicle safety system  100  utilizes the monitor  40  to provide visual notification and audio notification of detected objects within the monitored perimeter of the vehicle  5  so as to alert the driver of the vehicle and substantially reduce the probability of colliding with the object. Those skilled in the art will recognize that numerous types of visual and audio signals could be utilized to alert the driver of the vehicle  5 . 
     It is further contemplated within the scope of the present invention that the vehicle safety system  100  could additionally provide a speed governing function so as to control the rate of speed of the vehicle  5 . In this mode, the controller  10  would monitor data received from the global positioning receiver  30  and utilize to calculate the current speed of the vehicle  5 . The controller  10  would cross-reference the current speed data with data provided in the roadmap database to ensure that the current speed does not exceed the speed limit within the roadmap database by more than ten miles per hour. If the current speed exceeds the speed limit within the roadmap database that is allowed for the current position of the vehicle  5 , then the controller  10  will engage the brake actuator  50  so as to reduce the speed of the vehicle. While no particular level of brake pressure is required to be applied to the brake system  61  of the vehicle  5 , it is contemplated within the scope of the present invention that the braking pressure could range from a minimal force to sufficient force to cause the vehicle  5  to completely stop. It is contemplated within the scope of the present invention that the vehicle safety system  100  could govern the speed of the vehicle utilizing only current speed data. Additionally, it is further contemplated within the scope of the present invention that the vehicle safety system  100  would include an override function so as to permit the driver to operate the vehicle at excessive speeds if required.
