The invention belongs to the field of safety air bags, and discloses an ignition method and device of a safety air bag and a vehicle. The method comprises the steps that on the basis of first safety air bag simulation data obtained in a test of a target vehicle model, an ignition algorithm is started, a target ignition moment is obtained, and the first safety air bag simulation data comprises acceleration data under the ignition working condition and the non-ignition working condition; preprocessing the first safety airbag simulation data to obtain a collision acceleration value and a collision moment of the target vehicle type; and according to the target ignition moment, the collision acceleration value and the collision moment, the optimal ignition moment of the target vehicle model is determined, and safe ignition is conducted on a safety air bag of the target vehicle model. By the adoption of the method and device, the safety air bag can be ignited in time according to the optimal ignition time of the target vehicle model, and the timeliness of ignition of the safety air bag is guaranteed.
