DIY Safety Device to help prevent being rear ended

Here is a great video from the Goldwing Docs forum administrator. More and more cars on the road have Automatic Emergency Braking (AEB) to avoid having the driver rear end the vehicle in front of him. The problem is motorcycles are not as readily visible to the AEB radar as is a car. WingAdmin shows how to make a simple radar reflector that greatly enhances the return radar beam the car's AEB utilizes.


I haven't figured out yet how the best way would be to put one on an RT but I'll be working on it. If someone comes up with a solution please post it. We need to help keep each other safe out there!

Here's a link to the Goldwing Docs forum posting. https://goldwingdocs.com/forum/viewtopic.php?f=10&t=63779
 
So you could do the same thing he did and mount it in the large Saddle bag. Or mount it in the trunk. Very interesting idea. Thanks for posting. I got tired of the sales pitch so skipped to 7:33 where he starts describing what he did.

Dammit!! :banghead: Cos I'd originally skipped to 8:33 or thereabouts, when you posted that ^^, I thought I might've missed something important, so I went back to check it out - I hadn't missed anything! :gaah: . Then aaalllll the important stuff was over less than a couple of minutes later!! :shocked: . And some people say my posts are too long..... :p :rolleyes:

Still, it really is a good idea with more'n more cars being equipped with frontal collision assist that might miss our Spyder/Rykers cos they don't present a great reflective surface from behind :thumbup: . If anyone wants to read up on the theory of Corner Reflectors or more correctly, 'Trihedral or tetrahedral radar reflectors', check this out:

If I put one on my Spyder, first thing that would happen is a ticket from a radar gun speed trap.

I have more than once come across where one leo sits in a spot where you don't see them until you go pass them. Then I will come across a group of Leo's further down the road who are picking up the speeders the first leo tagged from the back as they passed him.

Oh! So -15 over! :spyder::roflblack::spyder:
 
I like the concept & will give some thought to size and location; not just on our Spyder but on my bikes as well. One question for any of you engineers with knowledge of radar/microwaves; what would be the minimum size of such a device that will still deliver the desired results?

I am setting here thinking about if our 2020 Ford Edge ST could test out this radar reflector. Guess I will have to study up on how it works regarding speed etc. Time to dig into the owners manual. Back in a few.

On edit:

Using the Pre-Collision Assist
System
The system is active at speeds above
approximately 3 mph (5 km/h) and
pedestrian detection is active at speeds
up to 50 mph (80 km/h).
E156130
If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system is designed to provide three levels
of functionality:
1. Alert
2. Brake Support
3. Active Braking

Alert: When active, a flashing visual
warning appears and an audible warning
tone sounds.

Brake Support: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking.
Brake support does not automatically
apply the brakes. If you press the brake
pedal, the system could apply additional
braking up to maximum braking force, even
if you lightly press the brake pedal.

Active Braking: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.

Note: Brake Support and Active Braking are
active at speeds up to 75 mph (120 km/h).
If the vehicle is equipped with a radar
sensor, included with Adaptive Cruise
Control, then Brake Support and Active
Braking are active up to the maximum speed
of the vehicle.

Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.

So it appears I could test this right on the street in front of our place. I have some silver HVAC duct tape. I will give it a try.

OK, here is step one. Coated inside and out. 4" on the three long sides.

Please do not drive over the mini wheats.

Well no workie, I drove at it at 15 MPH and mini wheats would have been rear ended. I changed the Pre-Collision setting from normal sensitivity to high with the same results. Guess I have to go drive at a parked car the same way and see what happens?
 
Radar reflector

Snoking, please let us know the results of your testing with the Ford Edge. That way we will know if this triangle will work for Spyders. I hope it does .

Well I was a little too early with my reply. Where did you mount the refector?

On the wheats box and drove right at it at 15MPH! It was at the same level as the sensor on the front of the Edge. That pre-collision is one of the things at Ford's free ST Experience driving school that you test. This is a free driving school for people that buy a Ford Explorer ST or Edge ST model. Diner and hotel, then the next day a road course in one of their SUVs, skid pad, pre-collision and they laps on a track.
 
OK, have to test it again. It appears the camera at the top of the windshield is in play also. I will set it up on my shop stool and try again.

This is from another poster on here:

"Active Braking: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely."

For Active Braking, it states may activate. So, my question is: For those people who have this type of system in their cars/trucks, and don't seem to notice motorcycles anyway, do you think you'll be safe from their brain inactivity? Or, did I read the Active Braking statement wrong, and it will activate automatically, bypassing the brain dead auto/truck driver?
