| titleOfInvention | Method for detecting abnormal shaking of power source rotating speed of new energy vehicle |
| abstract | The invention discloses a method for detecting abnormal shaking of the rotating speed of a power source of a new energy vehicle, which comprises the following steps: s1, receiving a rotating speed signal from a power source; s2, calculating a rotating speed wave crest in real time; s3, calculating a wave trough in real time; s4, setting a peak-valley difference and a time length threshold value, and setting the peak-valley difference and the time length threshold value, wherein different setting standards exist according to different power systems, and the output shaft of the power system is used as a setting object, and the speed ratio is used for calculation; s LimPS ＝S LimOS *R oS (ii) a S5, calculating the peak-valley difference in real time, counting time, reducing the peak and the valley, and starting to time T when the peak-valley difference is larger than a set threshold value 0 Starting to time T when the peak-to-valley difference is less than a set threshold value 1 Duration T ═ T 1 ‑T 0 (ii) a And S6, marking abnormal jitter, and triggering abnormal rotating speed jitter alarm to mark the position when the timing reaches a time threshold. The invention is convenient for the vehicle control program to find abnormal states in time and carry out corresponding processing, and improves the driving feeling and the safety of the vehicle. |
