Circuit/System Description

The vehicle direction alert alarm warning (VDAAW) system is a convenience feature that detects an unintentional lane departure. The VDAAW system informs the vehicle operator of deviation from the road lane markings. The VDAAW system consists of the VDAAW module which includes a camera and an On/Off switch which is a soft key located on the navigation radio system. The VDAAW system receives switch inputs from the navigation radio via the serial data circuit. When the system is working and can detect lane markings, the VDAAW indicator in the IPC illuminates. The VDAAW indicator illuminates green when the system is operating properly and flashes amber when the vehicle crosses a lane marking without the turn signal. An audible warning sounds three times when the amber indicator is flashing. The VDAAW system will not warn the operator if the turn signal is on or if the operator makes a sharp maneuver. The VDAAW system communicates with the IPC via the serial data circuit.
