Autonomous-Driving Vehicle Control With Composite Velocity Profile Planning

This article develops autonomous-driving vehicle control with a composite velocity profile (CVP) planning. An innovative technique of path planning is presented in the vehicle coordinates to allow complete lane change from any position at the origin lane to the center of the target lane. A technique of control is also presented to allow lane-change control design with vehicle speed planning. The CVP consists of longitudinal and lateral velocity profiles in time and planar geometric domains in the vehicle coordinates, respectively. This article also develops an autonomous-driving control framework with decentralized speed/lateral control using the CVP. The stability of the autonomous-driving control system is mathematically proved. Some experimental results on a test vehicle are also presented to demonstrate the utility of the proposed autonomous-driving vehicle control with CVP planning.
