In the method, a vehicle-mounted device obtains image information and radar information and determines a main lane line of a road in a driving direction of a vehicle according to the image information. The vehicle-mounted device determines an obstacle located on the main lane line and obtains motion parameters of the vehicle and the obstacle by fusing of the image information and the radar information, and calculates an estimated collision time period from now to the vehicle collides with the obstacle based on the motion parameters, and calculates a braking time period of the vehicle and outputting an early warning in response that the braking time period is less than the estimated collision time period.",
