## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of priority to U.S. Provisional Application Ser. No. 62/260,034 filed Nov. 25, 2015, the entire application which is incorporated by reference in its' entirety.


FIELD OF INVENTION
This invention relates to vehicles, and in particular to systems, devices, and methods for providing a switch adjacent to a vehicle turn signal lever or computer program control to increase frequency rate of the on and off front turn lights and rear turn lights when the vehicle is attempting a U-turn which indicates to oncoming and following vehicles.
BACKGROUND AND PRIOR ART
Existing turn signal controls typically are controlled by a steering column-mounted control stalk/lever arm mounted next to a steering wheel. The stalk/lever arm is generally moved to pivot upward (clockwise) and downward (counter-clockwise). The control stalk/lever arm generally actuates a set of mechanical switches inside the steering column and/or other types of circuits and/or vehicle computer controls so that upward (clockwise) movement causes a right turn signal switch to be activated and downward movement (counterclockwise) causes a left turn signal switch to be activated. The lights can include factory installed turn signal lights on the front and back of the vehicle sometimes with the vehicle exterior break lights.
Generally, the turn signal control will remain in an upward or downward actuated position (thus, activating a respective set of exterior turn signal marker lights) until it is returned to the neutral, center or “off” position, which can occur after the vehicle has completed a turn or the driver mechanically moves the stalk back to the neutral initial position. U.S. Pat. No. 5,614,884 to Evans, which is incorporated by reference in it's' entirety shows and described prior art type turn signal controls,
In operation, the driver wishing to make a left turn or right turn are mandated to give a signal and will generally engage the turn lever arms adjacent to steering wheels, which causes the front left and right turn lights and rear left and right tail lights to start a slow blinking process. However, there are problems that can occur if the driver wishes to make a full u-turn on the road.
Following vehicles at a traffic light stop or a vehicle in motion will sometimes start tailgating the vehicle in front trying to make the u-turn, since the following vehicle does not know that a u-turn is about to be done. This tailgating can cause the vehicle in front to be nervous and possibly attempt the u-turn faster which can be dangerous if there is oncoming traffic.
Additionally, the following driver may even run into the driver making the u-turn because they misjudge the forward vehicle's intentions, and wrongfully assume the forward driver is making a turn but not a u-turn.
Oncoming vehicles also may not understand the vehicle is making a u-turn. Thus the oncoming vehicle may assume a turn is being done which does not cause the oncoming vehicle to slow down, which can cause an accident to occur.
Attempts have been made over the years to try to create signaling devices for indicating a u-turn, but come with additional problems.
For example, U.S. Pat. No. 4,994,786 to Schaffer and U.S. Pat. No. 5,731,755 to Boxer, and U.S. Patent Application Publications: 2005/0168347 to Sanicola; 2005/0179533 to Stevenson; 2005/0237174 to Hu; 2007/0069881 to Dohan; 2014/0091920 to Thompson; and 2007/0184935 to Wallis, each describe devices that require mounting of extra lights to a vehicle such as lights configured in U or C shapes and/or different colors to indicate a U-turn. In addition to the extra expense of materials and labor, such devices could affect vehicle warranties, by needing to be permanently mounted. Extra lights and components can also interfere with existing signal lights and be prone to failure.
U.S. Patent Application Publication 2005/0083191 to Levin describes a button switch accessory to the current in use signal direction lever that causes turn lights to flash with extended delays between being lit and/or flash in continuous on-states. Such delays of the signal light flashing and extending the on-state of the signal lights can easily cause confusion to the following and coming vehicles, who may believe that the front vehicle is still making a turn. The long delays would not provide an extra indication to the following vehicle.
Thus, the need exists for solutions to the above problems with the prior art.
SUMMARY OF THE INVENTION
A primary objective of the present invention is to provide systems, devices, and methods for providing a separate switch or a computer program control to increase frequency rate of the on and off front turn lights and rear turn lights when the vehicle is attempting a U-turn.
A secondary objective of the present invention is to provide systems, devices, and methods for providing a user-activated switch or computer program control to use existing turn signal lights at a different flash rate speed that indicates to following and ongoing traffic that the vehicle is not making a basic left and right turn.
An embodiment of the u-turn light system for vehicles, can include or consist of a switch adjacent to an existing turn signal lever having an pre-set flashing rate frequency, and a flash rate increase control attached to the switch and existing turn signal lights on a vehicle, wherein activating the switch causes the existing turn signal lights to flash at an increased rate over a flashing rate of the existing turn signal lights.

The invention offers improvements on existing turn signal controls that can include an additional mechanical switch over the existing mechanical turn signals that can run on either or both circuitry and/or software, described in U.S. Pat. No. 5,614,884 to Evans, which is incorporated by reference in its' entirety.
Turn signals are required to blink on and off, or “flash”, at a steady rate of between 60 and 120 blinks per minute (1-2 Hz) according to United Nations (UN) regulations.
FIG. 1 shows a turn signal lever arm 14 with separate switch 20 to be activated by driver before making a U-turn. The switch 20 can be a depressible button switch on the turn lever arm 14. In this embodiment, the novel turn signal switch 20 is shown attached to an end of a turn signal lever arm that is attached to a steering wheel column 12 which also supports a steering wheel 10. Alternatively, the U-turn switch can be located on the center console 4 or on the dashboard 6. As shown in FIG. 1, activating the turn signal lever 14 by pushing up or down as shown by the clockwise/counter-clockwise double arrow, can also light up an existing left turn signal light 16 or right turn signal light 18 on the instrument panel 8 below the windshield 2 inside of the motor vehicle.
Additionally, activating the U-turn switch 20 can light up either both the turn signal lights 16, 18 or one of the turn signal lights to indicate the intended turn direction of the vehicle.
FIG. 2 shows a turn signal control diagram 100 according to the invention. Referring to both FIGS. 1 and 2, the driver can activate anyone of at least three switches 110, which can correspond to the switches on the turn signal lever arm 14. Here, pushing lever arm 14 upward can activate right turn light 18, right turn control 112 for existing flasher controls 120 in the vehicle to turn on existing front right turn light 132 and existing rear right turn light 134. When using the mechanical switch, the driver pushing lever arm 14 downward can activate left turn light 16 left turn control 114 for existing flasher controls 120 in the vehicle to turn on existing front left turn light 136 and existing rear left turn light 138.
The U-turn control can be computer activated in the case of driverless cars, without having to activate a mechanical switch.
Activating U-turn signal switch 20 activates control 116 for the new flasher increase rate control 140, which can either light up all turn lights 132, 134, 136, 138 with an increased flash rate or only the lights on the side of the vehicle in the direction of the vehicle turn.
Activating the switch 140 can cause the flashing signals from the existing front and rear turn lights to flash at a substantially faster rate than activating of the only the turn signal lights. For example, activating the switch 20 can cause the use of current state of the art LED (light emitting diodes) lamps signal lights to flash twice or three times as fast as just the activating of the turn signal lights.
The faster rate can be approximately 120 to approximately 240 to approximately 360 blinks per minute faster than the rate allowed by current UN regulations. If the vehicle rate of flashing is 60 per minute, the flashing for the U turn switch activation is at least approximately 120 per minute up to approximately 360 per minute. The increase will be a steady state minimum of at least two times the current steady state flashing rate in your vehicle signal turning light.
A faster flash rate would indicate to following vehicles and ongoing vehicles that the flashing vehicle is doing more than just a turn, and would cause those other vehicles to pay greater attention and caution to the vehicle with the fast flashing turn lights.
The invention would require minimal extra cost in materials and installation. The switch 20 can run by an extra flasher circuit, such as but not limited to a type of rheostat control and/or flasher relay, and the like, to increase the rate of flashing.
Alternatively, the vehicle computer can be programmed to allow for the extra flashing speed by being connected to the extra switch 20. Still furthermore, the invention can be a combination of a circuit and programming of the vehicle computer.
While the switch 20 is shown on the end of a vehicle turn lever 10, the switch can be on the side of the turn lever, or the base of the lever, or on the steering wheel, or any other location within each access of the driver. Although the switch can be a depressible button, the switch, can be a slide switch, or other type of switch, such as but not limited to a toggle switch, and the like. The switch can be spring biased to spring back after being depressed.
The invention does not require the mounting of additional lights and equipment that can cause undue material expense and labor for installation, as well as potentially void the vehicle's warranty. The invention can use only the existing front and rear turn signal lights.
The invention can have the other lights on the vehicle such as any one of the brake lights by themselves, and/or in combination with the head lights and rear lights to also flash (blink on and off) when the switch 20 is activated.
The invention can be factory installed by a vehicle manufacturer. Alternatively, the invention can be provided in an aftermarket kit to be installed by the vehicle owner or a knowledgeable vehicle repair person.
The invention can be used in driverless vehicles, where the vehicle computer can activate the U-turn control 110 shown in FIG. 2.
While the invention has been described for use on vehicles, such as motor vehicles, the invention can be used on other forms of transportation, such as but not limited to motorcycles, boats, golf carts, off terrain vehicles, and the like.
The term “approximately” can be +/−10% of the amount referenced. Additionally, preferred amounts and ranges can include the amounts and ranges referenced without the prefix of being approximately.
While the invention has been described, disclosed, illustrated and shown in various terms of certain embodiments or modifications which it has presumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
