Smart Cruise Control - Map

Smart Cruise Control — Map (SCC-M)

What It Does

SCC-M uses downloaded OpenStreetMap data to anticipate road changes — curves, speed limits, and intersections — and adjusts cruise speed proactively through ICBM.

How It Works

1. OSM map data provides information about upcoming road geometry
2. SCC-M calculates appropriate speeds for curves, speed zones, and intersections
3. Speed commands are sent through ICBM to adjust cruise before reaching these road features

Requirements

!!! info "Requirements" - ICBM must be enabled - Vehicle must support ICBM - OSM Maps must be configured and downloaded

How to Enable

Settings → Cruise → Smart Cruise Control — Map

Settings Reference

See Cruise Control Settings for configuration details.
