The invention provides a method used for assisting automotive stopping, wherein a parking space is measured by means of a sensor arranged in the automotive through an analysis processing unit (11), the analysis processing unit (11) is connected to a data bus (15), and the present running resistance of the automotive is calculated through inquiry of the data bus, therefore kinematic measurement parameters of each automotive system are analyzed and processed, and the limit of parking space is measured by the analysis processing unit (11) when the change of the running resistance surpasses a preset value.
