The project describes the development and implementation of a digital driving system for a semi-autonomous vehicle. CAN communication protocol is chosen to realize the objective. The main issues to be considered for the control of a vehicle are speed control, fuel monitoring, temperature monitoring inside the vehicle, pressure monitoring of the vehicle tyres ,engine pressure and the driver-vehicle interface.
A vehicle was generally built with an analog driver-vehicle interface for indicating various parameters of vehicle status like temperature, pressure and speed etc. To improve the driver-vehicle interface, an interactive digital system is designed. A microcontroller based data acquisition system that uses ADC to bring all control data from analog to digital format is used. Since the in-vehicle information systems are spread out all over the body of a practical vehicle, a communication module that supports to implement a one stop control of the vehicle through the master controller of the digital driving system.
