The invention discloses a method for judging the motion behavior of a vehicle based on an acceleration sensor. The method comprises the following steps that (1), the three-axis acceleration sensor is fixed to the vehicle; (2), the relationship between a three-axis acceleration sensor coordinate system and a whole vehicle coordinate system is calculated; (3), an acceleration value obtained by the three-axis acceleration sensor is collected; (4), according to calibration parameters obtained in the step (2), the value obtained by the three-axis acceleration sensor is projected to the whole vehicle coordinate system; and (5), according to a calculation result of the step (4), vehicle motion is judged by combining the relevant standard of the vehicle motion in vehicle engineering. According to the physics principle and vehicle engineering practice, a simple and efficient algorithm is provided, the motion situation of the vehicle can be judged only by means of the three-axis acceleration sensor; and by combining po
