Radar Technologies
TRW's AC100 24 GHz radar makes mass market introduction of safety systems like Forward Collision Warning (FCW) and Following Distance Indication (FDI) affordable.
With an appropriate interface to an electronic stability control system, the radar safety function can be extended to provide emergency braking with limited deceleration (Collision Mitigation Braking – CMB). With the addition of an interface with the engine management system and an adequate human-machine interface (HMI), the function can be further upgraded to include Adaptive Cruise Control (ACC).
Adaptive Cruise Control based on 24 GHz or 77 GHz radar technology senses the distance and relative speed of the nearest vehicle in front. The ACC system provides automatic acceleration, deceleration or braking to maintain the driver's selected headway.
The use of radar-based sensing technology (both 24 GHz and 77 GHz) provides a family of high-performance sensors with direct measurement of distance and relative speed. Radar is capable of operating under all weather conditions and may be used for functions that autonomously decelerate the vehicle.
