Driver Drowsiness Detection (DDD)

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The Driver Drowsiness Detection (DDD) aid observes the driver's techniques for signs of driver fatigue.

DDD only becomes operational when at 32 mph (50 km/h) and will not operate below this.

The Image Processing Module (IPMA) hosts the DDD feature and will communicate with the Steering Angle Sensor Module (SASM) within the Clockspring (CLKSPG), the Powertrain Control Module (PCM), the Anti-lock Brake System (ABS) control module, the Body Control Module/Gateway Module (BCM/GWM) assembly and the Instrument Cluster (IC). The IPMA communicates with these modules using High Speed (HS) Controller Area Network (CAN) bus messages and Local Interconnect Network (LIN) bus.

When the DDM is in operation, the IPMA will monitor the SASM for vehicle drifting. The IPMA will also monitor the brake pedal and accelerator pedal for inconsistent pedal use.

If the IPMA detects signs of driver fatigue, the IPMA will inform the driver by displaying a two stage warning message in the IC message center.

ITEM	DESCRIPTION
A	Warning message - Stage 1
B	Warning message - Stage 2

If the IPMA, SASM, PCM, ABS control module, BCM/GWM assembly or IC fails then the Driver Drowsiness Detection system becomes inactive.
