Going 35mph approaching an intersection... clear sunny afternoon no rain or snow.

My lane in middle goes straight, a left turn lane on the left, a right turn lane on the right.

As I approach, the signal is green, nobody in front of me. Someone in the left turn lane, stopped and waiting.
Adaptive Cruise Control SLAMS on the brakes for absolutely no reason. My wife, kids in back are like WTF.
Sure, it probably detected the stopped vehicle in left turn lane. But that's a problem. Nobody was in front of me at all.
Luckily nobody tailgating me at the time also.

I'll be submitting this to NHTSA. I suggest everyone else do the same.

WARNING
Improper use of ACC with Low Speed Follow can lead to a crash.
Use ACC with Low Speed Follow only when driving on expressways or freeways and in good weather conditions.

Suspect they will do precisely nothing with it.

All depends on the proximity settings of your ACC.

Dont forget, agencies like NHTSA will have tested the Honda Sensing suite before allowing it onto production vehicles - I'd be very surprised if they take any action at all.

Why use cruise control on city streets? The car also will not see pedestrians or bicycles in your way. I would only use cruise control on the open highway, certainly not in a high traffic area. The CRV is certainly not close to being an autonomous vehicle and should not be treated that way.

 

[Sweats]

In the end, you have to drive the car. Sure, enjoy all the safety stuff, but drive the damned car.

NHTSA will do nothing with any single complaint, except enter it into the database. They look for numbers of similar events and other patterns.

Especially when it was being used in a way not intended by the manufacturer.

Please read your manual. Adaptive Cruise Control should only be used on expressways such as interstates. Accidents caused by using these features are your responsibility. Even Tesla owners complain of phantom braking and no braking when needed.

 

[JeffJo]

Reminds me of the one who complained that he had trouble reading his book, because Lane Keeping kept ping-ponging back and forth.

BUT....

It is possible to use ACC with your foot lightly on the accelerator. If it does something unexpected, you can override it by pressing the pedal. The trick is knowing when it might, like passing stopped cars in the next lane.

Just like it is possible to use LKA with your hands lightly on the wheel. I can't tell you how many times I've gotten the "steering required" message on straight highways, when I was actually steering but the combination of LKA and my last input about a mile ago was enough.

 

[beww]

NHTSA will appreciate a good laugh.

They could probably make some money by publishing a book of "interesting" complaints.

I've noticed that ACC is sensitive to traffic, particularly on your right. I've had the ACC drop speed while passing another car on my right, typically if the car is moving significantly slower such as passing someone getting ready to exit. ACC picks up again once past the car. I never use ACC on city streets. I suspect that ACC was programmed to pay attention to things it detects in adjacent lanes (or on a sidewalk on city streets) and decide that too much speed difference is unsafe. I wonder how that sort of thing works in self driving cars.

No way to tell. There are no "self-driving" cars on the road, no matter what Musk says, and charges money for.

Setting aside the fact that you do not even understand the limits of your ACC, you also do not understand how and what it looks at when working to protect you from possible collisions.

Tip: it detected something that concerned it, and it did so at the very low end of it's range of operation (low speed). It is designed to be a bit conservative, rather than missing something that could cause you harm. Which means you will get the occasional false positive event. Sunlight hitting the front facing camera suddenly from reflecting off of glass of another vehicle can and will cause an alert too.

FACT: sometimes you get a false positive when a sensor gets spoofed or fooled by something in the environment.

Personally, I would rather have the occasional false positive than to have the vehicle miss something and put me and my family in harms way.

Note: HondaSensing is NOT self-driving capable and should not be relied on for driving decisions. It is a safety enhancement system at the current release level.. a second set of eye, hands, and feet on the controls assisting the driver.

You can certainly report your event to NHTSA. But when you do, please be factual, and do not post multiple times as some owners who are bent over something insist on doing.

HondaSensing, not just ACC, does alert on adjacent traffic sometimes, particularly at highway speeds. Normal and the reason is that in ACC the vehicle is trying to be alert to possible "lane jumpers" (you know.. the jack rabbits that jump lanes at speed, with no warning or signals.

ACC in current HondaSensing is not meant for local street driving really, so not using it in that situation is prudent. I'm sure the next version of HondaSensing will have all-speed ACC, but clearly it's a next generation event for CRVs. The key aspect to going live with all-speed ACC is actually fully capable front and rear pedestrian detection.

 

[mrtn]

The system is not manufactured by Honda but one of the very few big OEMs (Bosch, Continental, etc) and all the cars using those behave the same way.

 

[fdthird]

I’ve noticed the acc does sometimes see cars in an adjacent lane and show down or if the highway turns, it interprets the car to your right as being in front of you and slows down. . Happened to me today on the Garden State Parkway. I always have my foot over the gas/brake and if the car thinks it should apply the brakes but I don’t, I step on the gas and over ride it. It happens.

 

[Auxiliary]

I use cruise control a lot but i always have my finger on the cancel button ready to cancel it. I have seen the brakes slam on me if a car comes in my lane. I also own a new Venza and not sure if this is for all Toyotas' but i noticed it slows down and then will adjust, it doesn't slam like my CRV. I think Honda needs to build a better system.

 

[dbier]

I wonder how that sort of thing works in self driving cars.

It's possible many of the autonomous car promoters are wondering that too!

 

[jeffnick]

As a Boomer, these concerns about an "uncooperative" ACC amuse me.
