Lincoln Aviator: Collision Warning and Collision Avoidance System / Description and Operation - Collision Warning and Collision Avoidance System - Overview

Overview

The forward collision warning system works in conjunction with the ACC system. The forward collision warning system provides two major alerts for the driver in the event of a collision. A red warning indicator from the HUD module and an audible warning chime from the IPC. For this system, a HUD with driver information display is controlled by the IPC and illuminates a solid red bar that appears on the windshield in place of any other selected indicators. For additional information about the HUD,
Refer to: Collision Warning and Collision Avoidance System - System Operation and Component Description (419-03C Collision Warning and Collision Avoidance System, Description and Operation).

If the system senses the driver is not reacting, the CCM sends a message to the ABS module to charge the brakes for more sensitive braking or for automatic braking to slow or stop the vehicle to avoid or reduce the impact of a collision.

Forward Collision Warning System With CCM

During a possible collision event, the CCM commands:

• the IPC to activate the red warning indicator in the information center.
• the IPC to activate the red warning indicator in the HUD.
• the IPC to activate the chime message.
• the ACM to mute audio volume and signal the chime.

Forward Collision Warning System Without CCM

During a possible collision event, the IPMA commands:

• the IPC to activate the red warning indicator in the information center.
• the IPC to activate the red warning indicator in the HUD.
• the IPC to activate the chime message.
• the ACM to mute audio volume and signal the chime.
