The invention discloses a vehicle lane changing early warning method and device. The method comprises the steps that a lane changing request of a first vehicle on a target road is received; the lane changing request carries position information of the first vehicle and a to-be-changed lane identifier; determining a second vehicle and a third vehicle located on the lane to be changed according to the position information of the first vehicle; determining first collision time of the first vehicle with a second vehicle after lane changing and second collision time of the first vehicle with a third vehicle after lane changing; based on the first collision time and the second collision time, a collision risk result of the first vehicle after lane changing is determined; and according to the collision risk result, a lane changing early warning message is sent to the first vehicle. The collision risk result is determined according to the collision time of the first vehicle and the vehicle on the lane to be changed, the lane changing early warning message is sent to the first vehicle according to the collision risk result, and the lane changing safety and the passing efficiency of the vehicle are improved.
