This report presents two approaches to the design of the lateral controllers for commuter buses based on Sliding Mode Control (SMC). The objective of the control is to track the lane centerline. The first controller uses the sensor output which is a combination of yaw and lateral error. The...

Addresses issues regarding the implementation of an integration of several specific technologies involved in achieving lateral guidance of an experimental automotive vehicle on an automated highway. Results demonstrate the feasibility of the proposed discrete magnetic marker reference/sensing...

This is the final report for MOU 313, "Lateral Control of Heavy Vehicles for Automated Highway Systems". It address the following task items: Analysis and synthesis of control algorithms based on system identification and calibration results (Task 4. in the MPU), Closed loop results at highway...

This paper presents a study of vehicle traction control and discusses its importance in highway automation. A robust control strategy is designed for slip control, which in turn controls the traction. It is shown how traction control can be used to satisfy different objectives of vehicle...

This report introduces an optimal preview control algorithm which utilizes preview information pertaining to road curvature as well as superelevation angle for vehicle lateral control purposes. The optimal control law consists of both feedback control action and feedforward preview control...

This report is concerned with the dynamic modeling of the tractor- semitrailer vehicles in Automated Highway Systems (AHS). The objectives of the research are to characterize the dynamic response of articulated heavy-duty vehicles, identify the key system parameters, develop control algorithms...

This report summarizes an experimental effort in integrating and testing an automated vehicle lateral control system. The project, a cooperative effort between the California Partners for Advanced Transit and Highway ( PATH) Program and IMRA America, Inc., included a discrete roadway reference...

This report deals with the lateral guidance of vehicles, with focus on lane change maneuvers. Two approaches are presented for lane changes maneuvers. The first is to treat the maneuvers as a tracking control problem. A virtual desired trajectory (VDT) is used a tracking control approach. The...

The objectives of the project are: (1) to study the behavior of existing vehicle lateral control systems in the event of magnetometer failures, (2) to design controllers that use the output from only one set of magnetometers, and (3) to develop an autonomous lateral control scheme that uses no...
