The system software also differentiates between planned and unplanned lane departures. By combining the data it receives with the vehicle's speed, AutoVue can predict when a vehicle begins to drift toward an unintended lane change. When this occurs, the unit automatically emits a distinctive rumble strip sound, alerting the driver to make a correction. By using the turn signal, the warning will be cancelled. The rumble strip sound was chosen as the alarm after thorough scientific research proved it to be most effective for warning a driver without causing them to overreact.
Drivers are familiar with the rumble strip sound.
The sound does not startle the driver and they immediately know what action is required to address the alarm. Iteris has already received production orders for the AutoVue system from Freightliner. Sometimes just having a picture of the area you can't see is sufficient to avoid a collision. On the simpler side of vision assistance technology, conventional closed circuit video can provide the answer. An optional compact video cassette recorder can be added to these systems in order to provide an extra measure of security and protection.
