Method for checking survival space of automobile

The invention discloses a method for checking a survival space of an automobile. The method comprises the following steps of carrying out overall scanning on the interior of the automobile to obtain survival space 3D data, performing modeling according to the survival space 3D data to build a survival space model, importing a preset H-point calculation rule, performing calculation to obtain a current H-point position, importing crash dummy data into the survival space model to build a crash dummy model, and calibrating the crash dummy model according to the current H-point position; performingsimulation solving on the crash dummy model in the survival space model to obtain current survival space data; and judging whether the survival space data meets a standard space requirement or not, and if yes, outputting simulation data of the survival space model. According to the method, in a mode of building the model for performing space check and judgment, the cost can be effectively reduced, the calculation time is
