Abstract: This paper gives the design and implementation of the intelligent vehicle system using ARM cortex M4 as core controller for the purpose of safe and comfortable driving. Since ARM cortex M4 comes with many different features such as high efficiency, low cost and low power consumption. The system uses the speech recognition principle to improve the interaction between the human and machine. The system gives experimental results for five voice commands that are forward, backward, left, right and stop. The highly accurate ultrasonic sensor is used to detect the objects around the car. The system uses the CNG sensor which is highly sensitive to natural gas to detect the leakage of CNG from CNG kit, which is mostly used in vehicle nowadays.

Keywords: Intelligent vehicle, ARM cortex, speech recognition principle, CNG sensor, ultrasonic sensor.
