A Variable Look - Ahead Controller for Lateral Guidance of FourWheeled Vehicles
نویسندگان
چکیده
A variable look-ahead controller for the lateral guidance of vehicles for Automated Highway Systems is proposed. The control objective is to make the lateral error at a certain point ahead of the vehicle zero. The distance of this point from the vehicle is called the look-ahead distance. An input-output linearization controller to achieve this objective is proposed. It is shown that the yaw internal dynamics can be damped at all longitudinal velocities if the look-ahead distance is a certain quadratic function of the longitudinal velocity.

Lateral Control of Heavy Duty Vehicles for Automated Highway Systems
Three results pertaining to lateral control of heavy duty vehicles on Automated Highway System are presented. First, a time domain, frequency domain and pole/zero analysis of the linearized model for lateral control of tractor-trailer vehicles is presented. The steering response subject to variation of speed, road adhesion and look-ahead distance is studied. Based on the analysis, a simple base...
متن کاملAdvances in Fuzzy Logic Control for Lateral Vehicle Guidance
A candidate for intelligent control for lateral guidance of a vehicle is a fuzzy logic controller (FLC). The details of the most recent FLC with a rule base derived from heuristics and designer insight to the problem at hand, as well as a method for estimating a projected lateral displacement are presented along with simulation results. The structure of this FLC is suited to incorporate human k...

In this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. For vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. In accorda...
متن کاملFeedforward Compensation for Lateral Control of Heavy Vehicles for Automated Highway System (ahs)
In this paper, we propose a feedforward compensation method to enhance the performance of the lateral guidance system of heavy vehicles on automated highway systems (AHS). The feedforward controller blends well with the linear robust feedback controller. The proposed feedforward compensation is motivated by the analogy between a vehicle lateral control system on curved roads and a mechanical sy...

1 Improving Safety, Comfort and Efficiency of Convoy Vehicles Through Novel Preview Control Fuel consumption and emissions are major concerns associated with heavy trucks, and both can be reduced if the trucks travel in a very closely-spaced platoon [1]. The military deploys trucks in closelyspaced convoys where the terrain can be highly variable and the drivers often inexperienced. Traffic acc...
