Abstract

The invention provides a method and a device for judging jittering of an automobile. The method for judging the jittering of the automobile comprises the following steps of obtaining the speed running working condition of the automobile in a preset time period; obtaining the rotation speed extreme values of the automobile in the preset time period and the frequency sum of the rotation speed extreme values, wherein the rotation speed extreme values comprise the maximum and minimum rotation speeds of the automobile in the preset time period; according to the running working condition, the rotation speed extreme values and the frequency sum of rotation speed extreme values of the automobile in the preset time period, judging whether the automobile has jittering or not in the preset time period. The method has the advantages that according to the maximum and minimum rotation speeds corresponding to the running working condition of the automobile in the preset time period, the jittering of the automobile can be accurately judged in the test process of the whole automobile; by utilizing the results obtained by the method, the jittering of the batch-produced automobile in the actual running process due to inaccurate testing results can be avoided.

Description

technical field [0001] The invention relates to the field of automobile testing, in particular to a method and device for judging automobile shaking. Background technique [0002] At present, in the whole vehicle development process, since the vibration during the test process is completely judged by the test personnel themselves, when the test is insufficient, or the test conditions are not comprehensive or the driver's sensitivity is insufficient, the slight vibration of the vehicle may be brought to the test. To mass production caused customer complaints. Contents of the invention [0003] The technical problem to be solved by the embodiment of the present invention is to provide a method and device for judging the vibration of a car, so as to realize whether the car shakes in the vehicle test. [0004] In order to solve the above-mentioned technical problems, a kind of method for judging car shake that the embodiment of the present invention provides, comprises: [0...
