All these A.I. safety systems are unreliable. Look at all the controversy and accidents involving Teslas' self driving. I would be concerned about the airbags not deploying. Possibly your collision and the g forces involved were not severe enough to trigger the airbags.

 

Not only unreliable it makes people dumb and stupid. I kid you not, I know this supper "smart" person, a medical professional. Saw their car with a flat tire, and mentioned it. The answer I got was, "There is no warning light on the dash for tire pressure, it is OK".

 

Pretty sure the manual says "may not work under ALL conditions". I believe someone tested their 2 day old vehicle by driving into a building. Same results.

 

I remember some early 2019 posts where people stacked cardboard boxes in front of the RAV and it also did not auto brake.

 

It may be that the simple minded A.I. in the RAV4 only auto brakes for certain specific programmed shapes of MOVING objects. The YouTube videos demonstrating the system show tests involving pedestrians and bicycles moving sideways across the RAV's direction of travel. So if it does not recognize the shape of an object (for example, a dog) it may not auto brake. Or if an object is stationary (a building or stopped car) it may not auto brake. I do NOT trust the auto braking system or the similar back up/reverse warning system. The driver is always responsible for the car's actions and MUST be alert.

 

Here are examples to think about why the A.I. controlling the RAV4 auto braking system CANNOT be programmed to reliably stop the car in all cases: 1.You want to pull into your garage with a stationary wall in front of the car, 2. You want to park your car at a shopping mall or office building in the closest space next to the building's wall, 3. You are at Walmart and a car is parked in the space right in front of your space, 4. You are in dense urban stop and go traffic and want to move closer to the car in front of you. In such cases if the auto braking is too sensitive the car will be slamming on the brakes making it difficult if not impossible to get close to a wall or a parked and stationary car.

 

I believe the Pre-Collision System was not 100% designed to 'full-stop'.

It was designed to warn you to apply brakes, and it will brakes, but it won't do a full-stop braking action, just reduce the speed of the vehicle before the collision.

From what I recall back in the older 1.0 or 2.0 version, the PCS would NOT prevent a collision, it was meant more to lessen the effect of the collision, IE: you are still going to hit whatever you are about to hit, but you won't be hitting at the speed you were going to unless you actively hit the brakes.

What I recall also when I was told about this back in the day, Toyota dealers told me that it still requires the driver to pay attention, not rely on it to 'stop their car'.

 

It was designed to warn you to apply brakes,

It never gives a warning on the MID or an audible beep when you approach a wall of a building or a parked car. Possibly the RAV must be traveling above a certain MPH before such warnings are triggered. Also, possibly the RAV must be traveling above a certain MPH before any auto braking action occurs.

 

Here are some videos on how Toyota hopes the auto braking pre-collision safety system works.

 

thank you all, again I made a stupid mistake and was at fault. I didn't rely on the auto system, I bleeped up. I am just trying to figure out how things work

 

Here are videos showing how these auto braking systems actually work in the real world and how un-reliable they are. 5th generation RAV4 failures in first video at ,27,,57, 1:14 and 1.32 minutes.

 

I'm sorry this happened, I'd be curious to know what is in the vehicle logs during the time of the accident (viewable in TechStream).

Mine auto brakes aggressively, when vehicles are in the center turning lane and also when going around a gentle turn with cars parked on the shoulder. It's very jarring.

Sometimes when I accelerate away from a stop light while following another vehicle the car will flash a message that there is an object detected ahead and acceleration is reduced.

I guess Toyota went from not sensitive enough to way too sensitive.

 

The crash was at about 20 -25 mph but again no auto braking kicked in. I am trying to understand.

Not sure about the auto braking, but for the adaptive cruise control, the owner's manual specifically states the difference in speed between you and the car in front must be less than 20 MPH for your car to recognize the one in front and slow.

I remember some early 2019 posts where people stacked cardboard boxes in front of the RAV and it also did not auto brake.

The Toyota TSS system uses radar. Radar will not be reflected off cardboard boxes or other soft material. It may not even be reflective off harder materials if there is no metal in the material.

Subaru "eye sight" braking and adaptive cruise control uses two optical sensors at the top of the windshield. My Subaru Impreza would brake hard when the wind blew a tumble weed across the road in front of the car.

 

The Toyota TSS system uses radar. Radar will not be reflected off cardboard boxes or other soft material. It may not even be reflective off harder materials if there is no metal in the material.

If that is so then why would the Toyota system ever work to prevent running over a human pedestrian--a soft material target and not metal clad (unless he's a medieval knight in plate armor.)

 

Never trust the car to stop. I wouldnt want a car airbag to deploy going only 25mph.

 

Thank you all, I was not counting on the Toyota Safety system to hit the brakes for me, earlier in the thread I said I bleeped up and this is no me. I was just wondering why it didn't kick in and what to expect in the future
