Description

technical field

[0001] The embodiments of the present application relate to the technical field of intelligent driving, and in particular to an adaptive cruise system. Background technique

[0002] With the development of science and technology, the degree of intelligence of automobiles continues to increase, and self-driving cars are gradually becoming mature. Among them, the driving assistance system has entered the stage of large-scale commercial use. The key issues affecting driving assistance mainly include safety, comfort and energy saving, which largely reflects the level of development of driving assistance. Among them, advanced driver assistance systems such as cruise control, adaptive cruise control, and car-following systems can greatly reduce driver fatigue and improve driving comfort and traffic efficiency. It can significantly reduce the tension and fatigue of the driver, and assist or replace the driver to follow the vehicle in front in the dangerous situatio...
