Abstract
The invention provides an examination method and a piece of examination equipment. According to the method, an ideal velocity curve is established, and the fitting degree between a vehicle driven by an examined driver and the ideal velocity curve is compared to obtain the examination result corresponding to the examined driver. As the running velocity of many vehicles in the prior art can be recorded by a driving recorder, that is to say, in the invention, test equipment can automatically record the running velocity of a vehicle in each sampling point and generate an actual velocity curve, and parameters does not need to be entered manually, thus improving the degree of automation of examination. As a variety of parameters such as over-speeding or not and total running time can be directly reflected in the actual velocity curve, the examination method provided by the invention does not enable the examination result to be one-sided because the number of parameters entered in the test equipment is small. According to the test method provided by the invention, the actual velocity curve and the ideal velocity curve can be correspondingly input to make the examination process more transparent and more intuitive.
