Abstract
(EN)
A hybrid electric vehicle (1000) and an active vibration damping control method and device (100) therefor. The method comprises the following steps: when it is determined that a hybrid electric vehicle (1000) is in an idle charging working condition according to a vehicle speed sensor signal and a crankshaft sensor signal, calculating a target current value (A) according to a revolving speed and a vibration period of an engine and the motion position of a piston, communicating with a vehicle controller so as to acquire the charging power of the hybrid electric vehicle (1000), and correcting the target current value (A) according to the charging power to obtain a first corrected current value (A'); acquiring a delay time according to a camshaft sensor signal; and when the delay time is reached, applying the first corrected current value (A') to an actuator (21) so as to carry out vibration damping control on the hybrid electric vehicle (1000). Therefore, the present invention achieves active vibration damping control under an idle charging working condition, has a relatively high timeliness, and by predetermining the effective time of vibration damping and noise reduction control by means of a camshaft sensor signal, has a more effective vibration damping effect.
