Variable Intensity Brake Lighting Focussed On Ensuring Higher Road Safety

Abdul Adil Basheer, a student of Karukutty-based SCMS School of Engineering and Technology (SSET) in Kerala is riding high on confidence after developing an innovative solution to lighting solutions. The Variable Intensity Brake Lighting is an innovation that has got Basheer good appreciation from different quarters, including winning the runners-up award in the ‘Student Innovator of the Year’ category of Auto Tech Review’s Indian Automotive Technology and Innovation Awards (IATIA) 2018.

INTRODUCTION

Communication among drivers is mostly through light signals and horn. There are physical barriers for drivers inside vehicles, and they usually do not have adequate time to transmit their messages. These aspects can make it difficult for drivers to clearly understand the intentions of the other drivers.

The introduction of the Variable Intensity Brake Lighting technology is a step further in communication towards providing information on how hard the brake is being applied by a vehicle user. This technology is extremely handy especially during highway driving, as it provides more information to the trailing vehicle regarding the scenario in front of the vehicle. Basheer pointed out that the Variable Intensity Brake Lighting technology has an aesthetic element that makes the tail lamp dynamic and more appealing.

PROBLEM STATEMENT

Road safety has always been one of the most pressing issues worldwide. With the emergence of more powerful and fast moving vehicles on the roads coupled with highways and expressways allowing higher speed limits, there is a dire need for promoting and ensuring road safety now than ever before. The need of the hour is for drivers to coordinate with each other to share the road infrastructure.

For Basheer, the objective behind developing this innovation was to take the V2V (Vehicle-to-vehicle) communication a step further, ensuring a higher level of road safety. The project focusses on enhancing road safety through better driver-to-driver communication and assistive braking. The project also provides a design concept for future cars with end-to-end tail lamps.

SOLUTION

The proposed system consists of two sub-systems – ultrasound-based collision detection braking and variable intensity brake lighting. Basheer said both these sub-systems could function independently as well as together. The collision detection braking would consist of an ultrasonic distance sensor, which would detect the vehicle or object positioned in front of the vehicle and brake automatically, ascertaining the rate of reduction of distance between the two. The present system on cars is based on radar. The radar-based system is much more expensive as compared to the sonar-based system, Basheer noted.

Variable intensity brake lighting is an innovative concept that corresponds the vehicle’s tail lights to the intensity of the braking. This technology will be exceedingly handy for the drivers of trailing vehicles to respond to the vehicle braking in front, especially during highway driving in cases of emergency braking etc.

The proposed innovation is fairly simple and yet highly useful. The tail lamps merge into a functional as well as an aesthetically appealing part, where manufacturers can come up with creative implementations of the concept. The innovation provides a whole new scope for electronics engineering and design. The implementation can be done through use of energy-efficient LED Matrix so as to provide a more precise value as per the rate of deceleration. Since it is a step towards the future, the automotive industry has to bring about new concepts in design and functionality. Of course, with safety being a priority, the implementation of such innovations has to be promoted.

CONCLUSION

A dynamic tail lamp provides a whole new horizon for designers to manufacture and implement the technology. These aforementioned technologies will help drivers communicate better, and provide technological assistance that supports and protects from the drivers’ spontaneous road decisions in case of emergencies. This will go a long way in avoiding accidents, especially in the case of emergency braking on highways, where the car’s speed cannot be judged. Further, the implementation cost of the basic technology is fairly less; hence, it can be implemented on a whole range of vehicles, including two-wheelers and three-wheelers. The design can also be manipulated in case of more expensive vehicles so as to provide a visual presence for the on-road vehicle.
