Test Scenarios, Equipment and Testing Process for LDW LDP Performance Evaluation

2015-04-14
2015-01-1404
In this paper, a series of design, development, and implementation details for testing and evaluation of Lane Departure Warning and Prevention systems are being discussed. The approach taken to generate a set of repeatable and relevant test scenarios and to formulate the test procedures to ensure the fidelity of the collected data includes initial statistical analysis of applicable statistics; growth and probabilistic pruning of a test matrix; simulation studies to support procedure design; and vehicle instrumentation for data collection. The success of this comprehensive approach strongly suggests that the steps illustrated in this paper can serve as guidelines towards a more general class of vehicular safety and advanced driver assistance systems evaluation.

The Ohio State University has fielded teams at all three of the DARPA Grand Challenge and DARPA Urban Challenge autonomous vehicle competitions, using three very different vehicle platforms. In this paper we present our experiences in these competitions, comparing and contrasting the different requirements, strategies, tasks, and vehicles developed for each challenge. We will discuss vehicle control and actuation, sensors, sensor interpretation, planning, behavior, and control generation. We will also discuss lessons learned from the engineering and implementation process for these three vehicles.

A Multi-Level Automotive Speed Control

1996-02-01
961011
In this paper an automotive speed controller is developed for use in a car following scenario on an automated highway system. The throttle actuator used with the manufacturer's standard cruise control unit is used for throttle angle positioning and a multi-level control algorithm is developed for overall speed control. In addition, models of the throttle actuator, vehicle engine, torque converter, transmission, and longitudinal dynamics are presented.
