1.0 PRODUCT OVERVIEW
This system is designed to provide the Blind Spot Detection, Lane Change Assist and Rear Cross
Traffic warning features as defined by the ISO17387. It relies on two standalone 24GHz narrow band
radar sensors located in the rear corners of the vehicle. This radar complies with the low power 24 GHz
narrow band regulations (also known as low power non-specific short range or “ISM”) of most countries
such as European CEPT community, USA, Canada, China, Brazil and Japan.
The sensor has two modes of operations: It operates in a Blind Spot Detection & Lane Change Assist
mode when the vehicle is in forward gear or standstill and switches to a Rear Cross Traffic Alert mode
when the vehicle is operating in reverse. The sensor generates three different waveforms. Blind Spot
Detection is optimized for very near range detection (sub 10m), Lane Change Assist is optimized for
mid-range up (70m) and Rear Cross Traffic Alert is optimized for short range detection (40m).
