Smart Braking Concept

NEC Industrial Innovation Competition 2017 (2nd Runner Up)
As part of the design concept for the brakes, force retraction technology was introduced to incorporate into the bus model. It maximizes safety while minimizing space loss within the bus. This improvement of the current bus design would not have much impact on the passenger onboard capacity.
In this system, it addressed the concerns of standing passengers with irregular movements on the bus. It will provide a better balance control factor for the onboard users.
Ideally, the vehicle is broken down into two parts: 1) driver, front and back cases of the bus, and the front wheels; 2) back case of the bus, back wheels, and the passengers 'cabin.
As a result of the separation, FWD will become the vehicle's sole form of drive, giving the driver more control over the bus. In BWD, the bus runs on its own engine system. There will be a digital system integrated with the rear wheel to enhance and complement the front wheel during turns.
Separation Section Concept
During motion, the bus will extend by approximately 10 to 12 inches, which accounts for the pulling of the hydraulic system to re-set itself for the next stop.
In order to reduce any significant impact on the bus, a modified hydraulic braking system is to be installed. The purpose of the hydraulic brakes is to increase the force with less pressure. Using this concept in reverse, large impact forces can be reduced.
Separation Section Concept
When in motion, the bus's extended size can be observed, while the arrows point to the direction of compression when it stops.
In this design, improvements will be made to the existing bus without compromising the maximum passenger load or the exclusion of wheelchair users. By addressing the concerns that standing bus passengers have regarding falling when the bus moves erratically, this system will maximizes safety.
