Research on Automobile Rear-end System Based on Parameter Self-tuning Fuzzy Control

Abstract

With the development of China’s industry and the “Made in China” and “Created in China” proposals, the automotive industry has developed rapidly. Nowadays, China’s car ownership and sales volume has ranked first in the world. The rapid growth of vehicle ownership has also brought problems such as traffic congestion and frequent accidents. Traffic accidents often bring double losses of human and financial resources. Rear-end collisions should be given a lot of attention as high-incidence traffic accidents. This paper is based on the research of auto-tuning fuzzy control of vehicle auto-tuning system. Based on the vehicle’s sensors to obtain the optimal road surface slip rate and road peak adhesion coefficient, the driver’s input signal is synthesized, and the parameter auto-tuning fuzzy control is applied to multiple. After the fuzzy input is inferred from the complex input, the fuzzy output is determined to obtain the determined output signal effect and speed limit on the motor. At the same time, the safety distance of the actual road is predicted based on the peak adhesion coefficient of the road surface to remind the driver to drive safely and maintain the distance. This system can not only remind the driver to drive safely with a safe distance, but also limit the speed of the vehicle itself to ensure the safe driving of small cars.
