Dynamic Model Construction and Simulation Based on Intelligent Driving Vehicle

Abstract

In order to ensure the smooth, reliable and safe driving of intelligent vehicles, this paper combines the driving state information and energy transfer information of vehicles in traffic environment, builds a three-degree-of-freedom vehicle dynamic model and force analysis, and verifies it by software simulation. The results show that the dynamic model and control algorithm can ensure the safe driving of intelligent vehicles under complex constraints such as high speed, slip and roll, and effectively consider the influence of road curvature and terrain on the dynamic characteristics of high-speed vehicles to ensure collision-free driving. Hardware-in-the-loop simulation can connect the rapid prototype hardware system with the actual equipment to be controlled, and can repeatedly study the performance characteristics of the system when using different sensors and driving mechanisms .
