Road Departure Mitigation System Description - System Diagram

The system diagram of the RDM system is shown below.

For locations of each component on the vehicle, refer to Component Location Index:

The RDM system for this vehicle uses the multipurpose camera unit to calculate camera image information, and sends the RDM system indicated value to the control unit via the millimeter wave radar.
