Method for determining early warning moment of automobile anti-collision early warning system based on galvanic skin reaction

The invention discloses a method for determining the early warning moment of an automobile anti-collision early warning system based on galvanic skin reaction. An automobile anti-collision early warning system is an advanced active safe driving auxiliary system, and for the system, determination of the early warning moment is the key for achieving the active safe driving auxiliary function. Because the galvanic skin reaction can effectively reflect the psychological state change of the driver, the method determines the danger perception moment of the driver based on the galvanic skin reaction,serves as the early warning moment of the automobile anti-collision early warning system, and accords with the psychological characteristics of the driver. The method specifically comprises the stepsof acquiring the real-time galvanic skin data of a driver in the risk driving process; determining a galvanic skin reaction starting moment after judging that the driver generates galvanic skin reaction due to risk driving en
