DRIVER MONITORING (DM)
id151000005000
Outline
• The driver monitoring (DM) detects an action state of the driver (looking away, drowsiness level) by the camera inside the vehicle. If the system determines dangerous driving, it ensures the driver safety by warning display and warning sound.

Functions
Driver monitoring function
-
• The driver monitoring (DM) monitors the driver’s behavior (inattentiveness and drowsiness level).
Warning function
-
• If the driver monitoring (DM) detects driver drowsiness while monitoring the driver, it displays a warning screen on the multi-information display and activates a warning sound according to the drowsiness level.
• There are two types of patterns set for the warning.
-
― Warning pattern (caution): Fatigue or drowsiness detected
― Warning pattern (warning): Extreme fatigue or drowsiness detected
Personalization feature
-
• The driver monitoring (DM) can be set to ON (enabled)/OFF (disabled) (initial setting is ON (enabled).For details on the personalization features, refer to the [PERSONALIZATION FEATURES]

Driver monitoring function
-
• The driver monitoring (DM) monitors the driver when all of the following conditions are met.
-
― Driver monitoring camera is functioning normally
― Vehicle speed calculated by body control module (BCM) is
approx. 5 km/h or more for continuous
20 min or more
-
Note
-
• Once the vehicle speed becomes less than approx. 5 km/h, the driver monitoring (DM) will monitor the driver for approx. 3 min after the vehicle speed returns to approx. 5 km/h or more.
Warning function
1. The driver monitoring camera unit sends the driver information (driver's head position, face direction, line of vision, opening/closing angle of driver’s eyes, and opening/closing angle of driver’s mouth) (1) taken by the driver monitoring camera to the connectivity master unit (CMU) through the body control module (BCM) via CAN communication.
2. The connectivity master unit (CMU) calculate (2) the drowsiness level based on the driver’s eye information. If the CMU determines the necessity of warning, it sends the warning display request signal (3) to the instrument cluster and the warning sound request signal (3) to the body control module (BCM).
3. When the instrument cluster receives the warning display request signal, it displays the warning display on the multi-information display (4).
4. When the body control module (BCM) receives the warning sound request signal, it output the warning sound to the notification and warning speaker.

Note
-
• After warning pattern (caution) is activated, it will not be activated again for approx. 45 min.
• After warning pattern (warning) is activated, it will not be activated again for approx. 15 min.
• After warning pattern (warning) is activated, warning pattern (caution) will not be activated for approx. 45 min.
• If the vehicle speed is less than approx. 5 km/h, the warning function will not be activated for approx. 6 min. even if the vehicle speed reaches approx. 5 km/h or more after that.
• The driver information is used to accelerate the warning timing of the smart brake support (SBS).
