The objective of the project is to provide speed limitation to the electrical vehicle as per the speed sign boards. The system uses the RF (Radio Frequency) communication between speed sign post and the vehicle control system. Whenever a vehicle comes in range of the RF speed sign post, the sign post transmits the speed limit for that particular road to the vehicle system. The vehicle controller system receives this signal through RF receiver and processed through the microcontroller. If the system was at lower speed than the limit received from the sign post, then there will be no changes made to the speed of the system. If the speed of the vehicle was manually incremented to a higher value, then the controller will impose the speed restriction and bring back the speed value to the value specified by the limit. Now if the user tries to increase the speed, the system does not allow it to do so till it is in range of the RF speed sign post. The speed of the vehicle and the limits are displayed on an LCD.
