A method for predicting dummy head injury during an automobile collision includes: enabling a dummy head to collide with a rigid flat plate; obtaining a first data set in a collision process; calculating the maximum contact force of the dummy head and the rigid flat plate in the collision process according to the first data set; dividing a duration of the collision process into a plurality of time intervals; and calculating an injury value of the dummy head in each time interval according to the maximum contact force, and selecting the maximum injury value as a target injury value. The method provided by the present application may realize prediction for the head injury under different scene working conditions, and has the advantages of being simple in test flow, and high in prediction precision.
