<snip> Global automotive components supplier, Bosch, is currently readying a
new mid-range radar sensor (MRR) for series production. The new device is
seen as a less expensive version of the company's current LRR3 long-range
radar sensor, which also operates in the 77GHz frequency band. When
installed in the front of the vehicle, the new sensor has a range of up to
160m (525ft) and a detection angle of 450. The compact size of the new
sensor means that it can be easily integrated either the front or rear of
the vehicle. As a result of its range and angle of detection, vehicles on
the road ahead and those cutting in are detected early on, making it ideal
for ACC (Adaptive Cruise Control) systems. At speeds from 0 to 150km/h
(93mph), the system automatically controls the set distance to the vehicle
in front and will also activate a predictive emergency brake assist function
if another vehicle gets critically close. At speeds of less than 30km/h
(19mph), it will perform full automatic emergency braking.
Rear-mounted MRRs have a shorter range, but a wider angle of detection.
Sensors located in the rear corners create the basis for the lane-change
assistant, which monitors blind-spots and warns of vehicles that are
approaching quickly. Compared to existing 24GHz versions, a 77GHz sensor
delivers enhanced performance in all areas. <snip>
What this means is that you will never have an overtake as your car will
brake as you approach the rear of another car in the same lane and it will
perform full AUTOMATIC emergency braking as soon as a pedestrian steps from
the sidewalk when you are driving through town. Still, you'll have no need
to carry chump change to throw up at the windscreen of the guy too close
behind. The future is laughing at us already......
