Many of the advanced technologies and significant issues remain to be resolved before implementation. Inhibitors which could delay or preclude implementation might include unproven reliability, vehicle packaging issues and cost .vs. value as perceived by the customer.

Intelligent Vehicle Highway Systems

part 21 of 31

What it is :

The Intelligent Vehicle Highway System (IVHS) provides a variety of information to the vehicle and driver through cooperation of automotive electronics, communications, controls and systems engineering technologies. IVHS has two areas of interest to car and truck makers: (1) telematics and (2) active safety warning and control systems. Several features have been identified:

 Telematics:

 * Navigation systems

* Traffic messaging

* Emergency messaging and security tracking (e.g. RESCU - Remote Emergency Satellite Cellular Unit)

* Short range communications/ automatic toll collection

* Active Safety Warning and Control Systems

 * Collision warning/avoidance - Backup and parking aids - Side vision aid - Vision enhancement (all weather/night vision) - Adaptive cruisecontrol - Lane departure control

 How it works :

The IDC makes use of a phenomenon called stiction. Stiction is defined as the ratio of static to dynamic friction. The IDC mechanism utilizes patented valving technology to amplify the dynamic force to overcome static friction, which makes the door easy to move once it is in motion, but holds the door position when it is released or stopped.

Customer benefit:

Increased comfort and safety through exchange of real-time information on highway conditions and vehicle operating environment.

Ford status:

Under development.
