What is the difference between adaptive systems and cruise control?
2 Answers
Here is an introduction to the differences between adaptive systems and cruise control: 1. Cruise Control: Cruise control is the behavior of the vehicle's computer controlling the car to maintain a steady speed. Its main function is to automatically maintain the vehicle's speed without the driver needing to press the accelerator pedal, allowing the car to travel at a fixed speed. However, there is a minimum speed limit, and cruise control can only be activated when the speed exceeds this limit. 2. Adaptive Cruise Control: Adaptive cruise control appears more "advanced" than regular cruise control and is developed based on the cruise control system. Through continuous scanning by distance sensors, it can automatically control the vehicle's speed to maintain a safe distance from the car ahead. When the distance to the preceding vehicle becomes too small, the ACC control unit can decelerate by controlling the brakes and engine, maintaining a safe distance, while also alerting the driver with audible and visual signals to take active braking measures.
I've been driving long-haul trucks for over a decade and am very familiar with both cruise control and adaptive systems. Cruise control is the most basic—you set a speed and it maintains it without needing to press the accelerator, though you must always be ready to brake since it doesn't stop automatically. Adaptive cruise control is much more advanced, equipped with sensors that detect the distance to the vehicle ahead. If the leading car slows down, it automatically decelerates accordingly, and when the car moves away, it accelerates back to the set speed. It can also adjust speed based on safe following distances. Adaptive cruise is especially useful in traffic jams, as it largely handles acceleration and braking for you. But remember, it's just an assist—it may not react in time to sudden lane changes by other vehicles, so keep your hands on the wheel.
