Description And Operation
DESCRIPTION
The Forward Facing Camera Module (FFCM) is a stand-alone monocular camera mounted to the inside interior of the front windshield within the Combined Rear View Mirror Module (CRVMM) housing, that captures and processes video images.
The camera will perform the following functions on this model:
- Automatic High Beam Control (AHBC)
- Based on ambient situations, the AHBC feature will control the vehicle high-beam headlights automatically, relieving the driver of the manual operation of the high beam headlights. The AHBC feature automatically turns off the high beams when there is oncoming traffic, preceding traffic, presence of a village, high ambient lighting (for example, town, twilight, dusk, and others.), and when the vehicle driving speeds are too low.
- Object detection for supporting data fusion (ACC+)
- The camera provides additional object, lane and environmental conditions for data fusion. The FFC will also perform redundancy checks with the ACC radar to verify accurate detection.
- Lane Departure Warning (LDW+) - LDW+ utilizes camera-based machine vision sensor to detect and measure vehicle position within lane boundaries (when enabled). The system can be turned ON or OFF with a single hard button on the Integrated Center Stack (ICS). The driver can configure the torque feedback amount and warning zone start point through the personalization settings in the radio. Three settings for each are provided.
- Forward Collision Warning Plus (FCW+) - The FFC in conjunction with the radar sensor is used to detect whether the vehicle is approaching another vehicle in its path too rapidly and will warn/assist the driver in avoiding/mitigating the incident (when enabled). The driver has the ability to adjust the sensitivity and turn brake support ON or OFF in the radio.
The camera and bracket are not adjustable or repairable and must be replaced if inoperable or damaged.
OPERATION
The FFCM is powered by a fused battery feed from the Power Distribution Center (PDC) so that it is only active when ignition is set to the RUN position.
Auto High Beam Control - The FFCM module reports on the Controller Area Network - Chassis (CAN-C) bus to the Body Control Module (BCM) for messages needed for the AHBC functionality, and for additional detailed operating parameters of the AHBC system for additional description and functionality of the AHBC system. Refer to DESCRIPTION AND OPERATION .
Adaptive Cruise Control Plus and Forward Collision Warning Plus (ACC+/FCW+) - The FFCM reports to the Adaptive Cruise Control (ACC) module to create the enhanced ACC+ as well as the FCW+ operation. These components share a private CAN-C bus where data from the FFCM is sent to the ACC module for data fusion for additional description and functionality of the FCW+ system. Refer to DESCRIPTION AND OPERATION . For additional ACC+ operation information, refer to DESCRIPTION AND OPERATION .
Lane Departure Warning Plus (LDW+) - The LDW+ feature uses the FFC module to identify visible lane markings and to track lane boundaries. The FFC module requests haptic responses from the Electric Power Steering (EPS) system when required for additional description and functionality of the LDW+ system.
