Description And Operation
DESCRIPTION
| 1 - DASM |
The interior windshield mounted Drivers Assistance System Module (DASM) includes a camera sensor component and a radar sensor component both housed within a common single module housing. The camera component generally captures camera images of an area in front of the vehicle. The radar component emits fan-shaped radar beams so that objects generally in front of the vehicle reflect the emitted radar back to the sensor. The DASM processes the radar and vision data collected by the corresponding camera component and radar component and processes the information to support the various Drivers Assistance systems equipped on this vehicle.
The DASM communicates with other vehicle control modules via both public and private Controller Area Network (CAN) bus to provide the following features sets:
- Conventional Cruise Control - Only when equipped with a DASM.
- Adaptive Cruise Control with Stop and Go (ACC+)
- Automatic High Beam Control (AHBC)
- Advanced Emergency Braking (AEB)
- Full Speed Forward Collision Warning with AEB (FSRFCW+)
OPERATION
The DASM uses an integral radar and camera, by means of data fusion, to detect vehicles in the forward path of the vehicle that are moving, stopped or stationary and lane markings on the road.
How the DASM integrated or controls the various Drivers Assistance systems is covered in their respective service information.
