| description | The invention discloses an automobile anti-collision early warning method and system and a storage medium. The method comprises the steps: if a rear vehicle is detected to be exist, measuring the vehicle-to-vehicle distance between the rear vehicle and the vehicle; if the vehicle-to-vehicle distance is within a preset vehicle-to-vehicle distance threshold, calculating the collision time of the rear vehicle and the vehicle according to the vehicle-to-vehicle distance; and if the collision time is less than a preset time threshold, sending an alarm signal. According to the invention, if the rearvehicle is detected, the vehicle-to-vehicle distance between the vehicle and the rear vehicle is measured, the collision time is calculated according to the vehicle-to-vehicle distance, and if the collision time is less than the preset time threshold, the alarm signal is sent out to prompt a driver that the rear vehicle has rear-end collision threatening, so that the driver can take correspondingprevention measures.
