Some technical info about Toyota's Safety Sense systems.

On the Prius, the radar head sits behind the Toyota emblem on the front of the hood.

 

Thank you! But if I could ask for clarification, are you affirming that it's a phased array radar, as in the top of the post, or just adding that whatever radar it is, it's assisted by the camera?

 

AFAIK, the radar head directs a fairly narrow beam and it is the radar head which is connected to the front wheels' tracking in order to swivel towards the car's direction of motion. This swiveling action is also limited in movement, sharp curves will lose the tracked vehicle ahead and will need to be reactivated to resume DRCC.

 

I'd think literal physical motion would actually be more complex and failure-prone than a "steered" array in which nothing physically moves. And I'm hoping that my car has a radar array in the nose. How cool is that?

(And having high-tech things like having multiple motors/engines combined is one of the fun reasons to own a Prius.)

 

You are probably correct. All I know is that the radar is steering-sensitive to the steering vector. Good it all works is of no real interest to me as a driver.
