MG HS PHEV
Sometimes I think that developers who tune car systems never use them. I do. That's why I wanted to share a few observations about the (intelligent) adaptive cruise control (IACC) that works with the Lane Keeping Assist (LAC). Overall, these systems in the second-generation MG HS PHEV are fine.
However, two things annoy me:
1. The IACC and LKA systems completely deactivate with even the slightest press of the brake pedal. This behavior increases the risk because a driver accustomed to automatic braking with the lane keeping assist system engaged forgets that the system deactivates if they reflexively press the brake pedal, for example, in a traffic jam, and fails to apply the brakes again after reaching it (the lane keeping assist system deactivates after the first press of the brake). The solution to this problem is simple and obvious. Pressing the brake pedal should only reset the active cruise control speed, or CC. The distance and lane keeping system should be active at all times and, in fact, should be the default setting.
2. The speed setting method in the CC system is poor. Why would anyone program a dual joystick: increase (+) and decrease (-) the speed, first in increments of +/- 1 km/h, and the second with a long press of +/- 5 km/h? The first method is, to put it mildly, quite absurd, because who, for example, wants to drive at an exact speed of, say, 81 km/h or 99 km/h on the highway? It would be much more useful to use the car's current speed or the speed limit from Google Maps as the target speed (it's worth noting that speed limit recognition in GM doesn't work properly and should be disabled). The speed setting could be achieved by pressing the joystick from above.
