Self-adaptive cruise calibration method, device and equipment based on driver monitoring system

The invention discloses a self-adaptive cruise calibration method, device and equipment based on a driver monitoring system, and belongs to the technical field of automobile automatic control. The method comprises the steps that under the condition that a to-be-detected vehicle runs on a curve, if it is detected that an adaptive cruise control system is in an activated state and no lane line exists in a running route, the vehicle speed, the yaw velocity and the vehicle width of the to-be-detected vehicle are obtained; based on the vehicle speed, the yaw velocity and the vehicle width, a target area is determined, and the target area is located in front of the driving route of the to-be-detected vehicle; when it is detected that a target object exists in front of the driving route of the vehicle to be detected, whether an intersection exists between the contour of the target object and the target area or not is judged; and under the condition that the judgment result is that the intersection exists, the brakin
