FIG. 1 is a block diagram representation of a light management system (10) of a vehicle (20) in accordance with an embodiment of the present disclosure. In one embodiment, the light management system (10) corresponding to a vehicle (20) refers to various controlling mechanisms of lighting arrangements fabricated within the vehicle (20). In such embodiment, the vehicle (20) refers to a four-wheeler vehicle and the like. The system may be implemented only to daytime running LED lamps in head lamps and turn signal LED on tail lamps.
The system (10) includes one or more processors. The system (10) also includes a sensing module (30) operable by the one or more processors. The sensing module (30) senses pressure on an accelerator pedal of the vehicle (20) by a pressure accelerator sensor. In one embodiment, the accelerator pedal refers to a pedal pressed with foot to make a vehicle (20) go faster. Here, in conventional style, the accelerator pedal is positioned below the steering wheel. In such embodiment, the pressure accelerator sensor is manufactured with the accelerator pedal to detect the pressure applied via the foot. The sensing module (30) may be placed under the acceleration pedal as well inside the exhaust pipe.
In one particular embodiment, the accelerator pedal sensor will be standardly be present in the vehicle beneath the accelerator pedal. Commonly the pressure applied on accelerator pedal, or accelerator pedal sensor is the input for calculating the fuel required for the engine. The sensing module (30) also senses pressure of exhaust gas of the vehicle (20) by a pressure exhaust sensor. In one embodiment, exhaust gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal.

The system (10) also includes a speed calculation module (40) operable by the one or more processors. The speed calculation module (40) calculates a first speed of the vehicle engine (20) from the pressure sensed via a pressure accelerator sensor. The speed calculation module (40) may be placed within the daytime running LED lamps in head lamps and turn signal LED on tail lamps. In one embodiment, the engine speed calculation is estimated via analysing a first pre-set data. In such embodiment, the analysing process involves matching the sensed pressure corresponding to the accelerator with the pre-set speed, i.e revolutions per minute of the vehicle (20). The first pre-set data is stored in a first database.

Here, both the analysis will be same. Tachometer an instrument which measures the working speed of an engine (especially in a road vehicle), typically in revolutions per minute. In such embodiment, the tachometer provides revolutions per minute (RPM) information of engine, directly to a vehicular light illumination module (50). Such calculations by the tachometer may a primary or a secondary option to get the RPM information of engine, instead of Crank Shaft Speed Sensor. Tachometer is in dashboard of the vehicle.
The speed calculation module (40) also calculates a second speed of the vehicle engine (20) from the pressure sensed via a pressure exhaust sensor. In one embodiment, the engine speed calculation is estimated via analysing a second pre-set data. In such embodiment, the analysing process involves matching the sensed pressure corresponding to the exhaust gas output with the pre-set speed, i.e revolutions per minute of the vehicle (20). The second pre-set data is stored in a second database. It is pertinent to note, as vehicle is accelerated, the speed of the engine increases due to the internal combustion process, here from therein exhaust gas pressure increases. Therefore, the engine speed and the pressure are directly proportional.
Here, in one particular embodiment, the analysing process uses artificial intelligence and the like. As used herein, “artificial intelligence” refers to sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals, such as visual perception, speech recognition, decision-making, and translation between languages.
The speed calculation module (40) also compares the first speed and the second speed of the vehicle engine (20) to validate the calculation of the first speed. In one embodiment, the comparing the first speed and the second speed is established via a comparing technique. In one particular embodiment, the first speed and the second speed are compared for equivalence check to understand the correct measurement of speed. Here, in one particular embodiment, the comparing technique involves artificial intelligence and the like.
The system (10) also includes a vehicular light illumination module (50) operable by the one or more processors. The vehicular light illumination module (50) controls one or more parameters of multiple light sources associated to the vehicle (20) based on either the first speed or the second speed of the vehicle engine (20) calculated by the speed calculation module (40). The vehicular light illumination module (50) may be placed within the head lamp or tail lamp housing. In one particular embodiment, the system (10) controls the one or more parameters of the multiple light sources when the first speed and the second speed are equivalent.
Here, in one embodiment, the one or more parameters comprise at least one of voltage, intensity or combination thereof. In such embodiment, the intensity parameter is adjusted by adjusting the power in the lighting circuits. In another embodiment, the multiple light sources comprise taillights of the vehicle (20) or the head lights of the vehicle (20).
FIG. 2 is a block diagram representation of an embodiment representing the light management system working within the vehicle (200) of FIG. 1 in accordance of an embodiment of the present disclosure. In one particular embodiment, an accelerator pedal sensor (210) passes sensed pressure to engine control unit (220). Here, analysis is being done to understand the speed of the vehicle engine. After analysis, via the lamp control unit (230), the taihight (260) and the head light (250) are being control. The lamp control unit (220) is coupled to the vehicle body control (270). In another particular embodiment, a tail pipe pressure sensor (240) is being used in place of accelerator pedal sensor (210).

First, the pressure accelerator sensor (60) senses pressure on the accelerator pedal of the car X (20). Moreover, the pressure exhaust sensor (70) senses pressure of the exhaust gas corresponding to the exhaust pipe of the car X (20). Further, the system (10) calculates the engine speed of the car X (20) via a speed calculation module (40).

Here, by analysing technique, the system (10) analyses from a first pre-set database about the engine speed corresponding to the sensed pressure of the accelerator pressure sensor. The second way is to calculate the engine speed with respect to pressure of the exhaust gas corresponding to the car X (20). Here, by analysing technique, the system (10) analyses from a second pre-set database about the engine speed corresponding to the sensed pressure of the exhaust pressure sensor.
Further, the first calculated engine speed is compared with the second calculated engine speed using the speed calculation module (40). The comparing process enables validation of the detected first engine speed. The illumination frequency (80) of taillight as well as the head light of the car X (20) is controlled via a vehicular light illumination module (50). Particularly, the daytime running LED lamps in head lamps and turn signal LED on tail lamps are controlled.
In an exemplary embodiment, the illumination frequency (80) is controlled by regulating the voltage corresponding the illumination light sources. Here, in such exemplary embodiment, the illumination frequency may increase or decrease due to controlling mechanism.
