Today I woke up my car for a bit and it connected to the GM servers . I opened the My Chevrolet App and it showed the same engine oil remaining life which hasn’t changed since the end of October when I parked it. 55% which for 5300 km seems about right so it doesn’t seem to take into consideration how long it’s been in the engine. It also showed the increased tire pressure from when I bumped it up in December.
The thing I found interesting though was the software section that says the system is up to date. So I checked the update history and the last one says that the Adaptive Cruise Control system was updated to improve efficiency etc . Just wondering if anyone else noticed this as the general consensus seemed to be that the vehicle didn’t have adaptive cruise available. Although from everything I’ve read recently regarding this is in fact software based. So , did we get an upgrade, was it always there , or was it an update for another model of GM vehicle that got the same generic update code ?

You need to drive it for awhile for the oil life indicator to update itself. Not sure how long it takes but as a general rule it declines by roughly 10% per month whether you are driving or not but as I said it takes some driving in the spring for it to update.

Both can use either cameras or radar. I imagine even infrared can be used, but that's a guess.

Adaptive Cruise Control (ACC) uses a combination of sensors to monitor the distance and speed of vehicles ahead. The primary sensors include:
• Radar Sensors: These are typically mounted at the front of the vehicle and use microwave signals (often at 35 or 76 GHz) to measure distance and speed.
• Camera Sensors: These can detect lane markings and help maintain lane centering, while also assisting in detecting vehicles.
• Lidar Sensors: Some systems use lidar, which employs laser diodes to produce infrared light signals for detecting objects.
• Optical or Infrared Image Sensors: These may supplement or replace radar or lidar data for detecting vehicles ahead.

That's as generic as it comes. lol.
I think many use just cameras. It's cheaper. More expensive systems likely use microwave systems, but I doubt Chevrolet does.

Here's another generic answer.

Adaptive cruise control (ACC) uses sensors like radar or a forward-facing camera to monitor the distance between your car and the vehicle in front, automatically adjusting your speed to maintain a preset following distance; when no vehicle is ahead, it functions like regular cruise control, maintaining your chosen speed set by the driver.

Key points about ACC:
  • Sensors:
    A radar unit or camera system mounted in the front of the car detects the distance and relative speed of the vehicle ahead.

  • Driver input:
    You set your desired cruising speed and select the desired following distance.

  • Automatic adjustment:
    If the vehicle in front slows down, your car will automatically decelerate to maintain the set following distance.

  • Acceleration when clear:
    When the road is clear, your car will accelerate back to your preset speed.

  • Stop and Go functionality:
    Some advanced ACC systems can even bring your car to a complete stop in heavy traffic and then automatically accelerate when traffic begins to move again.

I’ll find the nitty gritty if you’d like…….a bit dry for most people I suspect.

Another question is do you prefer adaptative cruise control or the old fashioned style? I am of two minds and have had both. I found with adaptive if I was not paying close attention I would get behind someone a fair distance away and my speed would gradually reduce to below where I wanted to travel before I realized how much it had dropped. Good safety feature although a little irritating - I know I just need to pay more attention. All in all I probably prefer adaptive, after all many cars let you turn it on or off as well as vary the distance to the vehicle you are following.

I don't have adaptive and I'm not sure I need it or want it. I find it easy enough to modulate it with my thumb on the buttons.

In my most recent daily driver (Porsche Macan GTS) adaptive cruise was only available with one of Porsche's many option packages. I had no interest in the package and no interest in paying extra for adaptive cruise control so did not take the package. Porsche makes Corvette look like amateurs when it comes to packaging extra cost options in a way that makes you take options you don't want or need in order to get most popular options. One more part of the Porsche tax.

My other vehicles have it and I find it works great.
As the passenger, it does tend to freak my wife out at times as we make that rapid approach towards the vehicle ahead.
Nonetheless, I haven't rear ended anyone yet with the computer in control - let's hope the same holds true without it.

I have never driven a vehicle with adaptive before so I can’t really say but I don’t very often use cruise control to begin with. I prefer to be in control, one of the reasons being that it keeps you more attentive. Another reason is that it is sketchy on slippery surfaces especially black ice. At least in my Tundra it will try to maintain the set speed which of course causes the wheels to spin unexpectedly when they loose traction. Scary as JESUS H !!! It’s certainly fine in warm dry conditions but I still like to maintain full control myself.

Kinda like cable TV , lol .

I'd like to know what Chevrolet uses. What are the sensors on the C8? They don't look like cameras.

Found this…
The C8 Corvette uses wheel speed sensors to calculate speed. These sensors are integrated into the vehicle’s Electronic Control Module (ECM) and utilize data such as tire size to accurately determine the vehicle’s speed based on wheel rotation. Additionally, features like Speed Limit Assist use a front camera and embedded navigation systems to recognize posted speed limits, but these are not directly involved in speed detection. There is no mention of LIDAR sensors being used for speed detection in the standard C8 Corvette configuration.
The C8 Corvette does not use LIDAR sensors for its standard features. However, some aftermarket modifications might involve LIDAR or similar technologies for specific purposes. The Corvette’s advanced features, such as those in Super Cruise systems, use a combination of cameras, sensors, and map data, but LIDAR is not specifically mentioned for the C8 model. Additionally, discussions around radar detectors for the C8 Corvette focus on radar rather than LIDAR, as most police speed checking devices still use radar.
The C8 Corvette does not use infrared sensors as part of its standard safety features. Instead, it employs technologies like short-range radar for features such as Side Blind Zone Alert and Rear Cross Traffic Alert, and ultrasonic sensors for Rear Park Assist. There is no mention of infrared sensors being integrated into the vehicle’s safety systems.
