Testing the TSS on my new TRD Sport

Thank you for clearing up this misunderstanding.

 

It does work below 25mph, it simply can't be replicated without a need for the emergency brake.

 

It works anytime above 7mph.

A cardboard box can do the job to get the pre colision warning to kick on. An inflatable pool with painted red tail lights could possibly work to stop the car.

I’m so dumb...I never thought to use a box.

 

Lol it took awhile to get that one. We tried all kinds of things before choosing a cardboard box on set. Works like a charm but I will warn you it's loud! No damage to the cars we would do it on, but super loud.

 

Of all the answers, I think this is the best. Some are confusing the DRCC with pre-collision systems.

Pre-collision is always working above 7mph or so. It will take you to a dead stop, as much as physically possible, to avoid an imminent collision with pedestrians or even vehicles.

DRCC uses the same hardware to maintain cruise control distances at speeds above 25mph. Toyota states it will provide braking force to reduce speeds by 25mph if needed. So, if you're cruising at 60, it will take you to 35 no problem. I'm sure the actual number is greater, but that's what the manual states.

I love the DRCC, but always have my foot ready. It's nice to know pre-Collison is there, but I hope I never have to test it.

 

What’s with no air bags going off in this crash

Thank God everyone was alright! Looks like a rough accident. Now in regards to airbags going off, it all depends on injury to the passengers and the forces being put through the vehicle. If the system doesn't determine airbags are needed and the seatbelts are fine for the accident, they shouldn't deploy. Now if they deployed it could have injured the passengers (black eyes, cuts/bruises etc). The airbags are really just there to save your life, and although they can injure someone, it's better than being in a body bag.

 

NO. But again, it depends on what part of the TSS you are worrying about. The PCS part is always on, UNLESS you turn it off manually, and if you turn it off, there will be a light in the dash that comes on saying "PCS System Off", which is REALLY annoying. And then, once you turn the engine off, the next time you turn it back on, by default, the PCS system will again be turned on, which is as it should be. Other aspects of the TSS system, are the DRCC, which of course, is only active when cruise control is switched on, obviously. BSM [Blind Side Mirror] is active if you turn it on by pushing the button at the bottom of the dash. This informs you whether there is or are, objects in your "blind side", which is quite handy, as from my experience, there are plenty of blind sides in the truck! I personally just leave that button depressed, or "on", all the time. Then, another part of the TSS system is the Lane assist feature, which warns you ONLY, if you are digressing from the lane by crossing lines. This can be very handy if you are on a long trip and worry about getting tired and varying within the lane. This is also something that must be turned on by depressing the button on the steering wheel. It defaults to Off and must be activated when you want it. If you have the Technology package, which was an option, it warns you about people or objects coming at you from the rear or side, such as if you are in a parking lot and backing out of a space, if someone is walking towards the rear of your vehicle with a shopping cart, say, then the system would warn you that an object is approaching, which is a pretty good feature. This is automatic if you have this option. I think this covers it!

 

I think there is a huge misconception as to how TSS actually works. Does anybody have actual evidence to support the claim that the tacoma will automatically apply the brakes if it detects and imminent collision without the user input and without the use of cruise control or adaptive cruise control? Youtube video with a cardboard box?

I know that TSS-P is available in several other Toyota models which IS advertised to apply the brakes without user input, but as far as I know, Tacomas only have regular TSS (EDIT: TSS-C). (Or is my terminology incorrect? I mean to say that I only believe the sedans and minivans to be advertised as "automatic braking TSS" vehicles.)

I'm only skeptical because
a) I've never had my truck automatically apply the brakes outside of using adaptive cruise control.
b) On several occasions, I have triggered TSS during my daily driving, but it only results in the audio-visual alerts including "BRAKE!" displayed on the dashboard.
c) I've fallen asleep behind the wheel and hit a utility pole head on in my first tacoma without any interference from TSS.

Nevermind, my sticker says TSS-P.
And the TSS-P brochure confirms
"If the driver does not brake in a set time and the system determines that the possibility of a frontal collision with another vehicle is likely, the system may automatically apply the brakes, reducing speed to help mitigate the impact or avoid the collision entirely if possible."

It's not a claim....read the post above with the photo from the owners manual describing operation of the PCS w/PD (pre-collision system with pedestrian detection). I've had mine warn me a couple times, but I'm always ready to brake so it doesn't have to for me. But it's there if you need it.

The Tacoma (since 2018 MY) does have TSS-P. It's right in the owners manual and on the website. I believe TSS-C was an older system Toyota doesn't use anymore. Some newer Toyotas, such as the new Rav4, have TSS 2.0, which is basically TSS-P with some upgrades: Lane Tracing Assist - it'll actually steer you back into the lane when you drift, much like Subarus EyeSight system - the Tacoma doesn't have this because it still has hydraulically assisted steering, whereas most new crossovers/cars have electrically assisted steering; and FULL SPEED dynamic radar cruse control - meaning it'll bring you all the way to a stop when using the DRCC, as opposed to cutting off at 25 MPH like our Tacomas do.

 

Thank you, I was about to post this. So much false info given in other posts

 

I was thinking the same thing. People are confusing PCS with DRCC. Read your owners manuals!!!!

 

Thanks for clarifying, guys. Seems crystal clear now.

Last but not least, has anybody ever demonstrated this on a Tacoma? I know you're all rolling your eyes at me, but frankly, I've had the opportunity of testing this and now I'm on my second truck.

 

What year was your previous truck? TSS only comes with 2018+ trucks

 

I've never tested it, but IIRC there are some YouTube videos of people testing it. I have no desire to try it on a box or something. I trust Toyota, if they say it works, it works.

Also, ya, was your old truck a pre 2018 model? They added TSS-P in 2018....and the 4Runner's now get it for MY 2020.

 

First truck and current truck are 2018.

I really hate to be the skeptic, but this is the only one I could find.

The peace of mind comes from a real parking lot test, not an advertisement.

 

Ya, I thought there were more vids, but I couldn't find any either.

Since your such a skeptic...go out and test it yourself. Get a fridge box + an empty parking lot. Video it, put it on YouTube.

You said you hit a utility pole in your previous 18 - maybe the system couldn't detect that since it was just a pole and not a vehicle. Although it is supposed to detect pedestrians too.....I dunno.

My piece of mind comes from knowing I'm a good attentive driver, and I don't use my cell at all whilst driving. The TSS is there to protect me from the millions of inattentive drivers on the road.

 

I know the pedestrian detection looks for something human-like though. A pole is just a slender inanimate object. The radar/camera are looking for arms, legs, torso and head. The owners manual even mentions someone with a trench coat or holding a large bag wouldn't be detected.

But yeah, if you want to test it I would get a large cardboard box and that would set off the alert. Realistically though, the system is not focused on just avoiding an accident; its also to help "minimize damage". I don't work for Toyota but thats my understanding of the system.

 

Does anyone have experience with this system on a manual transmission truck?
