What are the drawbacks of adaptive cruise control?
2 Answers
The drawbacks of adaptive cruise control are: 1. Currently, some adaptive cruise control systems cannot achieve full-range cruising. The vehicle determines that adaptive cruise control can only be activated at speeds above 30 km/h and will deactivate below 30 km/h; 2. If the driver fails to notice the warning when the adaptive cruise control deactivates during deceleration and still removes their feet from the pedals, there is a risk of rear-end collision; 3. When braking and decelerating, with the feet off the pedals, both the reaction distance and braking distance will significantly increase. Adaptive cruise control is an intelligent automatic control system developed based on existing cruise control technology. During driving, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects vehicle speed signals.
Having driven for over a decade, the biggest hassle with adaptive cruise control is leaving my right foot idle to the point of distraction. Last time on the highway, it completely failed to detect sudden road construction cones—had I not taken over immediately, I would've crashed straight into them. Rainy or snowy days are worse; the radar gets blinded by mud and just quits. Once during a heavy downpour, it abruptly switched to standard cruise control, leaving me scrambling to hit the brakes. The most infuriating part is getting constantly cut off during follow mode—the system brakes a split second slower than human reflexes, forcing me to slam the brakes hard (three coffee spills in the backseat so far). In traffic jams, it accelerates like a timid newbie, inviting endless lane-cutting that just saps your will to argue.
