Keywords: Motor vehicle, Acceleration control, IR blaster and receiver, 8051uc, throttle control, air sensor, EMU.
Vehicular acceleration control has been a topic of extensive research for decades, which forms a major R&D topic in automobile companies. Vehicular acceleration control is defined as the acceleration control of a vehicle, like a motorbike or a car, under specific conditions immune to the driver. The basic idea of the paper is to control the acceleration and thereby the speed of a motor vehicle, using specific embedded modules at strategic points around a spatial area, which can be a Highway or an accident prone area, or an area where vehicular speed is to be controlled safely.
The idea works in two parts.
Firstly, an embedded IR blaster module is used to transmit encrypted IR signals of a specific frequency in an open area. This module can be powered by a battery or by solar energy, if used in open road areas. This module will blast an encrypted IR signal along the day at strategic directions. Different speed limits use different frequencies or modulation to distinguish them.
Secondly, in case of a motorbike, a throttle valve is controlled by the throttle in the handlebar, which when gripped and turned, allows more air into the carburettor, and an air sensor senses this inflow and increases the fuel injection by Bernoulli’s principle, i.e. air pressure decreases and hence fuel is drawn more. But always a residual air flow exists bypassing the valve, which maintains a minimal speed. In this case, if by means of an IR sensitive receiver module and by using a simple 8051 microcontroller along with the air sensor present, the air flow is controlled then the fuel injection can also be reduced which results in controlled acceleration and speed reduction, as air drag and friction provides the necessary slow braking.
The major advantages of this system are the cost reduction and the ease of implementation. This system is highly discrete and encapsulated and hence is portable and eligible for wide implementation in all vehicles.
The major use of this system is to control the acceleration and thereby the speed of a vehicle to the proposed limits in strategic areas as in HIGHWAYS, SCHOOLS & HOSPITAL AREAS, RESIDENTIAL AREAS AND OTHER ACCIDENT PRONE AREAS. The vehicle’s speed is controlled and accidents can be easily averted by this system. It also keeps the vehicle’s discipline of speed in check and provides safe roads for pedestrians and vehicles alike.

Why did you choose to work on this project topic : Nowadays, the rate of accidents in traffic hubs of the city has increased, mainly due to rash driving and non-following of traffic rules. Our idea is to prevent these accidents in prone places and near schools, hospitals etc. by controlling the acceleration and the speed of the bike at these places.
The integration of the electronic circuitry with the electrical throttle network which controls the engine throughput and acceleration is very feasible and it can be implemented in wide range of vehicles.
This project if implemented across wide domains and companies would result in a much safer and reliable environment where vehicular motion is controlled in accident prone places. This project would particularly make a huge impact in a country such as India, where rash driving, over speeding and breaking other traffic rules have become a everyday menace.
