This is the Future for Trailers!

What happens here

The truck accelerates to 75 miles per hour with the loaded trailer. While performing a panic stop, the driver also executes a single lane change maneuver. This simulates an 'oh crap' moment on the interstate where a driver needs to brake hard and swerve simultaneously. The system's ability to manage braking and maintain stability during such a complex and high-stress situation is highlighted. This maneuver would typically be very dangerous and difficult for standard trailer braking systems.

Goal: Observe the Hydrastar system's advanced control during a high-speed panic stop combined with a lane change.

Tools and materials

  • Hydrastar Hydraulic ABS System Hydrastar — Operating the trailer brakes during the test
  • Pratt Dump Trailer — Subject of the complex braking test

What they say

Hide

>> Okay. Thank you. Okay. So now this test, uh, Dan, tell me what we're going to do here, will you? >> So we're going to do another panic break apply at interstate speeds. Uh, but for this one, we're going to add a single lane change. So, what this simulates is another panicked stop on the interstate, but now instead of being able to shop stop short of whatever is in front of you, be it traffic jams, um we're actually going to go and we're going to take that next open lane to the side. >> So, imagine you all you go you're like the oh crap and you got to switch lanes while you're breaking. This is like the recipe for >> And so this is normally a no no with a trailer, but so what we're going to go for is if you're ready, we're going to go 3 2 1 >> panic break. We're going to grab that next lane, steer back in. Everything's under control. >> Ah, it's like these guys, they're reading my mind. >> Let's see what it looks like from the outside when we do a 75 mph panic stop with a lane change. And now you've got to realize there's a 4,000lb cement block in that trailer pushing that truck forward simultaneously. This is the recipe for disaster that hurts a lot of folks. Let's see how this new ABS system can handle it. All right, to get up to the proper speed, they go all the way around the test track. Then they come cooking down here and right here. They're going to All right. And we're going to stand right here and watch them cuz why wouldn't we all here they come?
