Abstract: A method for scribing a driving trajectory in the test on steering efforts of an automobile, characterized in that, the key points of the driving trajectory can be determined merely by using a tape measure according to the minimum turning radius of the front outer wheel of the automobile, in which the key points are determined by forming a triangle by making use of the flexibility of the tape measure through the distance from the key point to the centre point, the distance from the key point to the vertex and the distance from the centre point to the vertex. The method is simple, the instruments and devices used are very common, the stability of the instruments and devices is high, and the accuracy of key point determining is also relatively high.
