Beschreibung
Zusammenfassung:	The invention relates to a vehicle collision early warning sensitivity adjusting method and device. The method comprises the steps that the transverse acceleration of a current vehicle and the real-time vehicle following distance and the relative speed between the current vehicle and a forward vehicle are obtained; according to the real-time vehicle following distance and the relative speed, the remaining duration of the collision accident between the current vehicle and the forward vehicle is determined; under the condition that the residual duration and the transverse acceleration both meet the preset collision early warning condition, collision early warning prompt information is sent; obtaining obstacle avoidance operation data returned based on the collision early warning prompt information, wherein the obstacle avoidance operation data comprises an obstacle avoidance operation type and an obstacle avoidance interval duration between the moment of sending the collision early warning prompt information an
