What Does Full-Speed Adaptive Cruise Control Mean?
2 Answers
Full-speed adaptive cruise control refers to providing adaptive cruise control functionality across the entire speed range, which can be considered as a functional branch of adaptive cruise control. Full-speed adaptive cruise control allows the vehicle to activate while stationary, maintain safe following distance, and even follow the preceding vehicle to a stop and restart. Therefore, compared to standard adaptive cruise control, full-speed adaptive cruise control can further free the driver's feet, thereby better alleviating driving pressure. The adaptive cruise control button is located on the vehicle's steering wheel. While the full-speed range seems to cover a wide speed spectrum, it does not mean from 0 to the vehicle's maximum speed, but rather within a range of 0 to 150 kilometers per hour. This differs from standard adaptive cruise control systems, which typically only become active when the speed exceeds 25 kilometers per hour. When the speed drops below 25 kilometers per hour, manual control by the driver is required.
Full-speed adaptive cruise control is an advanced driver assistance feature that I found truly practical after test-driving multiple models. The system uses various sensors like radar to monitor the distance to the vehicle ahead, operating across all speed ranges—from zero to highway speeds—automatically controlling the throttle and brakes to maintain the set following distance. For example, it adjusts speed autonomously during highway cruising or handles stop-and-go traffic in urban areas without driver intervention. While standard adaptive cruise only works at specific speeds, this full-speed version provides comprehensive coverage, significantly reducing driving fatigue. Hardware-wise, it requires sophisticated computers and electronic control systems to process real-time data. In daily use, it enhances driving comfort, but requires keeping sensors clean to avoid misjudgments.
