HYBRID ELECTRIC VEHICLE AND ACTIVE VIBRATION REDUCTION CONTROL METHOD AND APPARATUS THEREFOR

摘要

A hybrid electric vehicle and an active vibration reduction control method therefor. The method comprises the following steps: when determining, according to an acceleration sensor signal and a crankshaft sensor signal, that a hybrid electric vehicle is in a driving growling working condition, calculating a target current value according to a rotation speed, a vibration period and a vibration amplitude of an engine, and also acquiring a vehicle speed sensor signal of the hybrid electric vehicle; correcting the target current value according to the vehicle speed sensor signal and the rotation speed of the engine, so as to obtain a first corrected current value; and acquiring an ignition coil signal of the engine, and when the engine is in an ignition state, outputting, according to the first corrected current value and the ignition coil signal, a drive signal with a working time to a drive circuit, so as to perform active vibration reduction control on the hybrid electric vehicle. The method can realize the active vibration reduction control of a vehicle in a driving growling working condition, and has a relatively high timeliness. The present invention further relates to an active vibration reduction control apparatus for a hybrid electric vehicle.
