What are the disadvantages of ACC adaptive cruise control?

[VonJesse]

ACC adaptive cruise control has the following disadvantages: risk control. The basic function of adaptive cruise control is to maintain the vehicle's longitudinal movement. When there is a collision risk, the vehicle will alert the driver and perform active braking intervention. However, actual road conditions are constantly changing, and the system cannot 100% avoid all risk scenarios, which may cause the driver to lower their vigilance. Having the foot away from the pedal position will increase reaction time. Adaptive cruise control can also be referred to as active cruise control, similar to traditional cruise control. The system includes radar sensors, digital signal processors, and control modules. In the adaptive cruise control system, the system uses low-power radar or infrared beams to determine the exact position of the vehicle ahead. If it detects that the leading vehicle is slowing down or identifies a new target, the system sends execution signals to the engine or braking system to reduce speed, thereby maintaining a safe distance between the vehicle and the one ahead. When the road obstacle ahead is cleared, the system will accelerate to restore the set speed, and the radar system will automatically monitor the next target.
