HANDFREE DRIVING

Postby Prasanth » Sun Aug 14, 2011 7:01 am

This seminar paper is based upon the project work being carried out by the collaboration of Delphi-Delco Electronics and General Motors Corporation. It was a named the Automotive Collision Avoidance Systems (ACAS) field operation program to built the tomorrow’s car. It used latest technologies of radar sensing to prevent collision. Video imaging to track its path, and uses GPS for locating the position of the vechile on the road. It completely utilized the latest technologies in Robotics as obstacle sensing, tracking and identification.


ACAS
It is the Automotive Collision Avoidance System (ACAS). The ACAS/FOT Program has assembled a highly focused technical activity with the goal of developing a comprehensive FCW system that is seamlessly integrated into the vehicle infrastructure.. The FCW system incorporates the combined ACC & rear-ends CW functionality. The ACC feature will only be operational when engaged by the driver. On the other hand, the FCW feature will provide full-time operating functionality whenever the host vehicle is in use (above a certain min speed). This feature is effective in detecting, assessing, and alerting the driver of potential hazard conditions associated with rear-end crash events in the forward region of the host vehicle. This is accomplished by implementing an expandable system architecture that uses a combination of: (a) a long range forward radar-based sensor that is capable of detecting and tracking vehicular traffic, and (b) a forward vision-based sensor which detects and tracks lanes. The proposed program effort is focused on providing warnings to the driver, rather than taking active control of the vehicle.

Due to the complexity and breadth of the system goals, the on-going design process has heavily relied on using the established principles of system engineering as a framework to guide this highly focused deployment design effort. As such, the technical activities of the program can be grouped into four main activities within two phases. Phase I started immediately after program inception in, June 1999, and lasted approximately 27 months. Phase II started immediately after the end of Phase I. The objective was that the two program phases will be continuous with minimal disruption of program flow and continuity between them. Consequently, activities that enable the continuous workflow into Phase II will be initiated during Phase I.
