Traffic incident influences the security of people in the popularity of navigation. It is urgently necessary to develop intelligent vehicles by using new technologies and advanced methodologies. In this paper, a new approach based on holonic conception is presented to study the intelligent control in vehicle tool. The control structure in car is divided into three levels and is defined three holonary, the function of every holon level is discussed, then a distributed multilevel intelligent control architecture in car based on holon is developed. The cooperation relation is analyzed between different levels; the cooperative model is established to study cooperation mechanisms among different holon level, which will help to improve the intelligent control and vehicle security for car.
