Abstract: For relieving the harms caused by rear-end accident, an intelligent automobile control system against rear-end collision is developed. Angle sensor technology, binocular vision range and millimeter wave radar ranging technology are integrated in the system and applied for distance and velocity measurement on curved roads and straight roads separately. In order to avoid automobile rear end collision, the results are calculated according to the mathematical model for safe distance and the speed is controlled by using fuzzy control algorithm. Then through the Matlab simulation results the validity of the control process is verified. In addition, Zigbee communication technology is used for the switch between high-speed operation mode and urban operation mode, thus the flexibility and reliability of the system are greatly improved.
