Abstract

The invention discloses an automobile and an active vibration damping control method and device thereof. The method comprises the following steps: calculating the vibration magnitude of the engine according to the fuel supply amount of the engine at the next moment, and calculating the rotational speed and the engine speed according to the crankshaft angle of the engine. Vibration period; obtain the target current output waveform according to the vibration size, speed and vibration period; obtain the ignition coil signal of the engine; judge whether the engine is in the ignition state according to the ignition coil signal; if so, according to the target current output waveform and ignition coil signal output band The driving signal at the working time is sent to the driving circuit; the driving circuit outputs the working current with the action time to the actuator according to the driving signal, and the actuator works according to the working current to control the active vibration reduction of the vehicle. Therefore, the active vibration reduction control of the car is realized, which has high timeliness and effectiveness, and the effective time of vibration reduction and noise reduction is directly obtained by using the ignition coil signal, and the vibration reduction effect is more effective.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an active vibration reduction control method for an automobile, an active vibration reduction control device for an automobile and an automobile with the device. Background technique [0002] With the advancement of social technology, people have higher and higher requirements for comfort, and ride comfort has become an important indicator to measure car performance. Among them, the main factor affecting ride comfort is car vibration, which causes car vibration There are many reasons for this, and engine vibration, as one of the main reasons, deserves attention. The engine vibration is mainly caused by the combustion in the engine cylinder and the reciprocating motion of the piston. The vibration is transmitted to the frame through the engine suspension system, and then transmitted to the cab, affecting the ride comfort. [0003] In order to improve ride comfort, it is neces...
