Driver Alert Control (DAC)
The Driver Alert Control (DAC) function is designed to attract the driver's attention when it senses swerving driving behavior, for example if the driver is distracted or is on the verge of falling asleep.
The FSM reads the lane's painted road markings and compares the stretch of road with the driver's steering wheel movements. The driver is warned via an audible signal and a text message when the vehicle does not continuously follow the lane.
The audible warning and text message are generated via the Driver information module (DIM) (5/1). The Forward Sensing Module (FSM) (4/80) transmits a request via CAN to the Driver information module (DIM) which generates the audible warning and text message. The Forward Sensing Module (FSM) also transmits the request to the Infotainment control module (ICM) (3/281) to silence the stereo sound from the loudspeakers during the period that the audible warning is generated by the Driver information module (DIM).
