FCWForward Collision Warning
Warns the driver when forward collision risk rises, using perception and decision logic.
Standards
- ISO 26262 development path
- Sensor-fusion perception
- Program-defined requirements
- AEB companion
System overview
Forward Collision Warning (FCW) uses the ADAS perception stack—including the documented 77 GHz radar and monocular camera—to assess frontal collision risk. Time-to-collision and threat logic drive visual, audible, or haptic warnings and can provide a coordinated input to AEB. Detection classes, range, timing, and environmental performance are defined and validated against the OEM program’s operating domain.
77 GHz radar and monocular-camera perception
Real-time classification of vehicles, pedestrians, and cyclists
Visual, auditory, and haptic driver-warning interfaces
Operating envelope validated against the project DVP
Technical profile
Capabilities and technical values are program-dependent and must be confirmed against the applicable OEM requirements, vehicle architecture and validation plan.
Problems it solves
- Solves slow driver detection of forward collision risk.
- Provides program-calibrated warning before the intervention threshold.
- Serves as the perception layer that triggers AEB.
Typical applications
- Vehicle programs with defined forward-collision warning requirements.
- ADAS suites where FCW feeds AEB and ABP.
- Platforms requiring project-validated forward perception.
