DETAILED DESCRIPTION OF THE INVENTION

[0012] FIG. 1 exemplarily illustrates a schematic diagram of a braking intensity indication system 100. The braking intensity indication system 100 indicates a force applied on a brake pedal of a vehicle comprises a sensor 101, a control unit 102, and an array of light sources 103. The sensor 101 is mounted on the brake pedal for generating sensor data variables based on the force exerted on the brake pedal. The control unit 102 for receiving the generated sensor data variables from the sensor 101. The control unit 102 is configured to analyze the received sensor data variables. The array of light sources 103 is in electrical communication with the control unit 102. The control unit 102 actuates one or more sets of light sources 103 from the array of light sources 103 for indicating the force applied on the brake pedal of the vehicle. The control unit 102, is for example, a micro controller, etc., that is programmed to translate changes in resistance applied to the sensor 101 mounted on the brake pedal. In an embodiment, the sensor 101 is, for example, a force sensitive resistor, etc. The sensor 101 generates sensor data variables, which is subsequently, sent to the control unit 102, for example, the microcontroller.

[0013] In an embodiment, the array of light sources 103 is, for example, Adafruit's Neopixel RGB LED strip to indicate from a central section outward the intensity with which a user is stepping on the brake pedal and changing the resistance of the sensor 101, the force sensitive resistor. The control unit 102 of the braking intensity indication system 100 comprises a memory unit 104 configured to store sensor data variables generated by the sensor 101. The control unit 102 further comprises at least one processor 105 communicatively coupled to the memory unit 104. The processor 105 is configured to execute computer program instructions defined by modules of the control unit 102. The processor 105 refers to any one or more microprocessors, central processor (CPU) devices, finite state machines, computers, microcontrollers, digital signal processors, logic, a logic device, an user circuit, an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a chip, etc., or any combination thereof, capable of executing computer programs or a series of commands, instructions, or state transitions. In an embodiment, the processor 105 is implemented as a processor set comprising, for example, a programmed microprocessor and a math or graphics co-processor.

[0014] The processor 105 is selected, for example, from the Intel processors such as the Itanium microprocessor or the Pentium processors, Advanced Micro Devices (AMD) processors such as the Athlon processor, UltraSPARC processors, microSPARC processors, hp processors, International Business Machines) (IBM) processors such as the PowerPC microprocessor, the MIPS reduced instruction set computer (RISC) processor of MIPS Technologies, Inc., RISC based computer processors of ARM Holdings, Motorola processors, Qualcomm processors, etc. The modules of the control unit 102 comprise a data communications module 108, an analyzing module 106, and a triggering module 107. The data communications module 108 is configured to receive the generated sensor data variables from the sensor 101. The analyzing module 106 is configured to dynamically analyze the received sensor data variables and determine the force exerted on the brake pedal. The triggering module 107 is configured to actuate the one or more sets of light sources 103 from the array of light sources 103 for indicating the force applied on the brake pedal of the vehicle. In an embodiment, turn signals are incorporated into the braking intensity indication system 100. For example, when the turn signal is prompted, the array of light sources 103 can have a chasing effect going from the center of the vehicle to the indicated turn side with a pulsating glow. These changes are developed into the braking intensity indication system 100 by re-programming the control unit 102.

[0015] The braking intensity indication system 100 disclosed herein is not limited to employing a processor 105. In an embodiment, the braking intensity indication system 100 employs a controller or a microcontroller. The processor 105 executes the modules, for example, 106, 107, 108, etc., of the braking intensity indication system 100. The braking intensity indication system 100 does not interfere with existing standard vehicle lighting. The braking intensity indication system 100 is installed as an addition to standard vehicle lighting and is installed with relative ease to the rear window or bumper of a vehicle using a suction cup or adhesive respectively. In an embodiment, the sensor 101 is mounted in a sleeve or other mounting device attached to the brake pedal surface. The microcontroller of the control unit 102 is installed in a concealed location and the electrical wiring is routed similarly around the vehicle's interior trim. The sensor 101, for example, the force sensitive resistor, mounted on the brake pedal does not require any sophisticated measurements for installation. Therefore, the force sensitive resistor can be installed on any vehicle brake pedal.

[0016] The force sensitive resistor varies resistance on force applied, not distance traveled. The braking intensity indication system 100 presents a universal installation rather than requiring specific considerations dependent on a make and a model of vehicle. The braking intensity indication system 100 incorporates a variable resistor (force sensitive resistor) as the primary sensor 101 sensing pressure applied to the brake pedal. The braking intensity indication system 100 does not take into account the travel of the brake pedal. The braking intensity indication system 100 uses one output pin that delivers a signal to the array of light sources 103, for example, the WS2812 Neopixel single wire protocol LED strip. By using the array of light sources 103, the braking intensity indication system 100 is not limited to a discrete number of LED's.

[0017] FIGS. 2A-2B exemplarily illustrates an electrical circuit diagram of a braking intensity indication system 100. In an embodiment, the control unit 102 is connected to the array of light sources 103, for example, the WS2812 Neopixel single wire protocol LED strip. In FIGS. 2A-2B, only two LED strips each of the array of light sources 103 are shown, as an example. In an embodiment, the array of light sources 103 includes at least two strips of 30 LEDs each. In an embodiment, a capacitor C1 is connected to the power supply V1 as exemplarily illustrated in FIG. 2A. The capacitor C1 protects the array of light sources 103 from damage when subjected to a power spike or a surge in power supplied by the power supply V1. The control unit 102 actuates the light sources 103 based on the generated sensor data variables received from the sensor 101 as disclosed in the detailed description of FIG. 1. The braking intensity indication system 100 incorporates a variable resistor (force sensitive resistor) as the primary sensor 101 sensing pressure applied to the brake pedal.

[0018] FIG. 3 exemplarily illustrates a method for indicating a force applied on a brake pedal of a vehicle. In the method disclosed herein, a braking intensity indication system 100 comprising a sensor 101 mounted on the brake pedal, a control unit 102, and an array of light sources 103, is provided 301. A force exerted on the brake pedal of the vehicle by the user is sensed 302 by the sensor 101, for example, the force sensitive resistor. The magnitude of the force exerted is determined 303 by the control unit 102. The one or more sets of light sources 103 from the array of light sources 103 is actuated 304 by the control unit 102 for indicating the force applied on the brake pedal of the vehicle.
