Abstract

Autonomous driving is now becoming a new popular technology in the vehicle industry. To achieve this goal, people need to control the vehicle movements especially the steering performance with corresponding pre-set algorithm. The main part of the steering system is an Electrical Power Steering system(EPS). EPS is a product widely used in the field of vehicle steering to save energy and create a safety, make a comfort performance with high efficiency and low power consumption.

This project focus on designing the steering unit control system of autonomous vehicles and by testing and verifying the performance and reliability to make a vehicle can steer by itself. Since the DC motor of EPS can be re-programmed in order to create different steering performance, people start to research on how to modify it to achieve the autonomous driving technology. The model and the dynamic behaviour of the EPS can be built and simulated on Matlab and Simulink hence designers can implement the simulation to analysis the impact of the steering system and find the method to handle these factors. By establishing PID controllers to adjust the outputs coming from the EPS to control the torque, speed and position of the rack of the system.

Finally, designers will test the steering performance with the help of the MicroAutoBox on the steering rig test bench of the laboratory, compare the tests results and the simulation results to adjust the parameters of the PID controllers to get a more reasonable steering model.
