Honda Crash Detection System

MImeKillEr writes "MSNBC is reporting that Honda Motor Co. unveiled an early crash-detection system for one of their vehicles. The system is unique in working even before the driver responds. A radar in the front of the car stashed behind the Honda logo detects vehicles within a range of about 300 feet ahead. It then taps the brake and tightens the seatbelt. A buzzer goes off and a light on the dash is illuminated. If the driver responds, the braking power is boosted. If the driver fails to respond, the system kicks in and brakes more while also tightening the seat belt. Unfortunately, Japanese regulations don't allow for the system to fully stop the vehicle."

DOes it work ?

Now I write radar software and I really don't have a clue how such a system can work reliably. A non-moving car 100m ahead ? That happens every time there's a parked car in a curb. Car radars are not like aircraft radars. The latter only has to see something ('anything') in the middle of a big mass of air. Nothing else around. A car radar would have to sort out lots of echos at various doppler: the ground is coming towards you (when it's far ahead), other cars going the same direction (slower in the right lane, faster in the left lane), cars coming the other way, parked cars, things hanging overhead (bridge, street lights. advertisement...)

Just imagine driving on a mountain road and out of a right curb comes a car driving the other way. The radar sees it right in front of you, coming your way. How does it react ? I'd hate to see it break suddenly, particularly if the road is wet or snowy.

It works fine. Check out the radar-based cruise-control from Mercedes, now available on a few models. You can set your cruise to follow a vehicle ahead automatically. You just steer, and the two (or more) of you can pass cars and go through tunnels just fine without the cruise control panicking.

Here's a link to more info from Honda

Hereâ(TM)s more from Honda:

So itâ(TM)s more than just the 300 ft test, which would be arbitrary. It looks at "distance, speed and and anticipated path".

Sounds worse than a backseat driver though.
