2014 Mazda CX-5: Fun With SCBS

July 1, 2013

2014 Mazda CX-5

Who needs coffee when you have the Smart City Brake Support (SCBS) system?

As I was pulling into our underground garage at work this morning, and approached the parking security arm, our Mazda CX-5 screeched to a noisy halt. Jolt! Wake up.

The SCBS had detected the parking barrier and thought I was going to get into a fender bender.

Our Mazda CX-5 owner's manual states that the SCBS will operate the brake control when the system detects a vehicle ahead. It goes on to say this does not apply to two-wheeled vehicles or pedestrians. (Or extremely dirty cars. No, really.)

However, it works pretty darn well when approaching the parking arm in our garage. The manual does say that it could operate when passing through a toll gate, which is pretty much the same set-up as in the photo above.

I guess I need to be more patient and not try to roll through as I wave my key card at the security sensor.

    So I'm going through the 20 mph EZ-Pass lane and this thing cranks the brakes on? And then I get rear-ended by the guy behind me.

    If someone rear-ends you when you come to a sudden stop from 20 mph, they were following way too close.

    @greenpony: In EZ-pass, I can easily see something like that happening. Anyways, I'm not going to pull out the "In Soviet Russia" joke I used on the ATS again, but this is pretty lame and a potential hazard.

  • greenpony, unfortunately, being technically in the right in a collision still doesn't doesn't make it fun dealing with insurance companies, loaner cars, paint matching, body work, etc. etc. --- I can't think of an instant when beeping at me wouldn't be more than enough of a wake-up call for stopping rather than having it stop for me with no regard for if I want it to or not.

    This system is active up to 19 mph. In an EZ-Pass 20 mph lane, everyone is coasting through @ 18 mph (so they don't get a nastygram from EZ-Pass), with their feet hovering over the accelerator pedal, waiting to go for it. The last thing they expect is that the car ahead is going to jam on the brakes. In the LT Infiniti JX35, they were headed up an inclined approach to a truss-style bridge, that system interpreted the overhead girders as being ahead of the vehicle because of the angle of the inclined approach, and it jammed on the brakes in that instance.

    The onus is on the driver behind you to pay attention. What if you were slamming on your brakes for real because a child just ran out in front of you? Or, to use the tollbooth example, if a tollbooth employee stepped out in front of you? Lest you misunderstand, I'm neither advocating nor opposing the use of automatic braking; rather, I'm commenting only on fault in a rear-end collision. Aren't you wondering where the fault would lie when computers take control from the driver?

  • "I'm commenting only on fault in a rear-end collision. " And I'm simply commenting on regardless of who's at fault it still wouldn't be any fun for either party. --- " Aren't you wondering where the fault would lie when computers take control from the driver?" ummm, haven't they?

    Does this "feature" have an off switch?

  • fordson1 fordson1 Posts:

    agentorange - best comment so far in this thread. And can it be defaulted to "off"?

    what a interesting surpise! Hold on to that latte

    For those wondering, yes it can be turned off. Also, an EZpass lane won't set it off. I've gone through a few toll lanes already in mine and it never set it off. It also waits till what seems like the very last second to activate, since the only time it's activated for me was a similar low speed situation approaching a gate. There haven't been any complaints on the CX-5 forums either, so aside from the occasional scare from the office parking garage gate, I wouldn't worry about it too much.

    Could the SCBS help out with parallel parking?
