adaptive cruise control

Adaptive cruise control (ACC) is a type of advanced driver-assistance system for road vehicles that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. As of 2019, it is also called by 20 unique names that describe that basic functionality. This is also known as Dynamic cruise control.Control is based on sensor information from on-board sensors. Such systems may use a radar, laser sensor or a camera setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to.
ACC technology is regarded as a key component of future generations of intelligent cars. The technology enhances passenger safety and convenience as well as increasing road capacity by maintaining optimal separation between vehicles and reducing driver errors. Vehicles with autonomous cruise control are considered a Level 1 autonomous car, as defined by SAE International. When combined with another driver assist feature such as lane centering, the vehicle is considered a Level 2 autonomous car.
Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself.

    Adaptive Cruise Control - Braking either on or off?

    I've rarely had the opportunity (or motivation) to use ACC but a recent longish trip on fairly fast straightish highways seemed like a good time to try it again. Sadly, despite an OTA firmware update and a 20,000 km service earlier this year I found that it seems incapable of the kind of...

    Adaptive Cruise Control issues after update

    Several software updates were performed during my MG4 SE LR first service in April. I now notice that the ACC function is behaving differently. It appears as if switching on ACC is now also enabling LKA, with the associated unpleasant steering nudges. Anyone else seeing this? One of my...

    Adaptive Cruise Control

    Does anyone know when using ACC whether the brake lights come on when ACC brakes due to slow/stationary traffic please? I want to know if someone following me gets a warning of rapid deceleration. Thank you.

    Adaptive cruise control ACC

    I've noticed if I drive on motorway at 70 mph and use the ACC and then use the brake to slow down, the battery will shut down. I recieve a fault and need to pull over. Shut the car down and restart and it works again. Is this a common fault or is there something I'm doing wrong?

    Any way to stop ZS EV resetting everything

    My new ZS EV arrived a couple of weeks ago and I'm loving the range but the software seems largely basic and in some parts just really badly thought out. Most of them I can get past but the settings reset is downright infuriating. It doing things like resetting the KERS level back to 3 and...

    Cruise control

    Can one turn off the Adaptive cruise control so it is just on manual operation that can increase or decrease speed levels in increments of 1 mph instead of 5 mph and not have the radar Influence which causes problems on bends on A roads.

    Adaptive Cruise Control and regenerative braking question

    I just did my first long motorway trip in the ZSEV. I love the ACC but I notice if the car slows from say 70mph to 60mph because of traffic ahead when it stops accelerating and starts breaking you don’t get any regenerative breaking so nothing on the automatic slow down is going back into the...

    Simple adaptive cruise control operation

    After a few weeks of trial and error, I have found the easiest and most effective way of using the adaptive cruise control is this: If you want to not have the car steer, but set a speed and follow the car ahead, use the adaptive cruise setting. If you want the car to steer and set the speed...

    MG4 - Adaptive Cruise Control (ACC) and MG Pilot

    , Is this true (If you have both settings on)?? - the car will accelerate and decelerate in the forward direction when in ACC (Green on dash?) according to the car infront- but will it also steer (if you were on a gentle bend such as a motorway ?) - I havnt yet attempted these yet - but thought...

    MG ZS EV adaptive cruise control efficiency

    Hello, everyone. As good as the car is, the adaptive cruise control can be really improved as now it gives me 15% INCREASE of energy USAGE compared to the same distance driven without using it. And it blocks the KERS system as well, and now this is outrageous. Any ideas how to bypass this and...

    Adaptive Cruise Control Default Distance

    Hi all, Sorry if covered elsewhere, I did do some searching, but couldn’t find it on the forums or in the manual. Is there a way to change the default distance on the ACC to be the minimum? When driving on a motorway it seems to be too harsh. Someone pulls in front and then it goes down to...

    Checked out the adaptive cruise control today, glad I had my seatbelt on, it worked, maybe not as fast as I would have liked but that might have been in the settings.

    Adaptive cruise control (ACC) behaving badly? Check your number plate.

    Update as of 27 December 2021: if you're having issues with ACC, check how your front number plate is installed; it could be blocking the radar - see post #17 below. Original post: Hi all, First post from a happy new MG ZS EV owner. I'd love to hear about your experience with adaptive cruise...

    Range when using adaptive cruise control or MG Pilot

    Is it just me, or is the car way less efficent when using the cruise control or MG Pilot? I seem to be able to drive the car far more efficently "manually". Don't get me wrong, both systems work incredibly well, though it is still a little disconcerting.
