Abstract
In this electronic era, modern automobiles are designed with electronically controlled throttles with CAN (Controller Area Network) [1] Bus which limits the vehicle's speed and protects the vehicle engine in a single cost-effective system. Generally, CAN Bus link is used to monitor the engine diagnostic faults and alerts the driver for one or more failure modes via an audible alarm or an LED. Our idea is to include the driver's emotional state as an additional feature for the control of speed. Firstly, the driver's emotional state such as sadness, anger, fear, disgust is analyzed by using the speech processing technique. When any one of this state is predicted, then the system incrementally limits the vehicle speed and ultimately limps to home mode until the driver comes to normal state or the engine fault is rectified. This system is mainly intended for avoiding accidents and road safety.
