What are haptic critical events?

never heard of it.

google it.

lots of answers.

 

In what context? ELD saying that? Which one?

 

I'm guessing some safety system felt the truck experienced some instability.

 

Schneider? We get haptic collision avoidance events when the truck senses you’re about to hit something. More often than not it’s the shadow of a bridge, or construction barrel or other such false alarm. At least at Schneider, they know it’s a bogus event and it doesn’t get reported to your DTL or show up in your safety metrics. Safety can see them but they don’t do anything with them.

 

IMO, that's not possible. Trucks and qualcomm's call that Out of Gear or OOG. It measures time where you are not in any gear, by placing shifter into neutral or by holding the clutch pedal in. Back in the day it was called "Georgia overdrive." Anyone with a Qualcomm can go into the maintenance screens, I forget what they call that page, and see your idling percentage, time overspeed, time with excessive speed, time out of gear, and several other things. I would google your truck manufacturer, and haptic critical event. I'm thinking it might refer to the truck stability system noticing something like braking hard while turning, drive tires slipping while cornering, or a hard steering input. I'm just guessing.
