Module Network Input Messages - IPMA

Broadcast Message	Originating Module	Message Purpose
Ambient air temperature	PCM	Used to control the IPMA camera heated windshield element operation. The IPMA may turn the heated windshield element on when the ambient temperature is below 5 °C (41 °F).
Hands off status	PSCM	Used to determine if a driver's hands are on the steering wheel when the lane keeping aid system is active. If a hands off condition is detected, the driver is alerted via the message center.
Head up display flash rate	CCM	Disables the lane keeping system in the event of a collision warning.
Ignition key type	BCM	Defaults the lane keeping system to alert mode when a MyKey ® is in use.
Ignition status	BCM	Enables and disables the IPMA based on the ignition switch position.
Lane keeping system suppression	PSCM	Disables the lane keeping system in the event of an evasive steering maneuver by the driver.
Lane keeping system switch status	SCCM	Used to communicate the lane keeping switch state to the IPMA.
Personalization mode	IPC	Used to configure the personalized options for the lane keeping system (mode and intensity).
Restraint impact event status	RCM	Disables the lane keeping system when a SRS event occurs.
Turn signal switch status	SCCM	When the turn signal is activated, this message is used to suppress the lane keeping on the side of the vehicle corresponding with the turn signal direction.
Vehicle yaw rate	RCM	Used for the lane tracking and feedback calculation.
Vehicle lateral acceleration	RCM	Used to temporary disable the lane keeping system in the event that the lateral acceleration of the vehicle exceeds a predetermined threshold.
Vehicle longitudinal acceleration	RCM	Used to temporary disable the lane keeping system in the event that the longitudinal acceleration of the vehicle exceeds a predetermined threshold.
Vehicle speed	PCM	The lane keeping system is only active when the vehicle speed is above 64 km/h (40 mph).

Module Network Input Messages - PSCM

Broadcast Message	Originating Module	Message Purpose
Calculated steering angle	IPMA	Provides a reference steering angle for PSCM intervention.
Lane keeping alert request	IPMA	Request to provide haptic feedback (vibration) through the steering wheel to alert the driver of a lane departure.
Lane keeping aid request	IPMA	Request for steering torque when a lane departure is detected and the lane keeping aid is on.
Road curvature data	IPMA	Provides road curvature as detected by the camera. Used to calculate required steering torque for lane keeping aid interventions.

Module Network Input Messages - IPC
