dynamic cruise control vs. adaptive cruise control

Aren't they the same thing???

 

I believe they are, but perhaps somebody has owned one of each and can comment on any differences.

 

Honda Clarity ACC does more. It follows the car ahead to a fully stop. It will pick up the speed by itself from zero when it is moving again without you doing anything.

I have tried in my Prime but I need to push the gas pedal to resume unless I was not patient enough. I read somewhere now DRCC has full speed for select model which can do the same as Honda ACC.

 

To me, that just sounds like two companies choosing different acronyms, and slightly different feature sets, for what is fundamentally the same capability. So, if Toyota were to remove the requirement that we tap the gas after DRCC has taken the car to a stop, there wouldn’t likely change the name of that feature to ACC.

I presume that Toyota requires us to tap the gas as a perceived safety measure. That is, to protect against it crashing into the car ahead in the event that its radar somehow loses the car in from of it (which I have seen it do, strangely!).

 

You can also briefly lift the cruise control stalk (as if you wanted to increase the cruise control set speed), to get going again.

 

Yes, “Adaptive Cruise Control” is what we called it at my previous company, where we sold microcontrollers that Bosch, Continental, etc. used to implement such systems.

 

I still like the Honda ACC to a full stop then resume on its own (very nice on a highway traffic jam almost like an autopilot).

You could be right that Toyota to be more conservative for us to tap the gas to resume as a safety measure but they have revamped the new DRCC so it can resume by itself when it is cleared in select models only.

Toyota/Lexus are improving/adapting the standard. Like the new TSS 2.0, pretty sure 3.0 coming soon ... CarPlay/Android Auto...

When Honda implemented the first generation of ABS called it as ALB... battle of the naming standard

 

Just wanted to chime in that although the cruise control will slow the vehicle to a stop, it does so at the very last moment akin to an emergency stop when the driver is not putting on the brakes. Even when at the furthest distance setting, it fails to read the cars ahead speed. It will often accelerate in an attempt to bring the car to cruise speed, then brake heavy to slow down. Complete fail from Toyota. This speed and stop and speed and stop process contributes to greater traffic.
