Engine damping control device and method

Abstract

An engine vibration damping control device and method. The engine vibration damping control device is connected to an engine and a motor, and includes a frequency domain filter, a processor, a converter and a controller. The frequency domain filter receives the vibration signal generated by the engine and converts the vibration signal into a frequency domain signal, wherein the frequency domain signal includes vibration position information. The processor is connected to the frequency domain filter and receives the frequency domain signal and calculates the vibration reduction control signal according to the vibration position information. The converter is connected to the processor and receives the vibration reduction control signal and converts the vibration reduction control signal into a time domain signal. The controller is connected to the converter and receives the time domain signal and controls the motor to output reverse torque to the engine according to the time domain signal.

Description

technical field [0001] The invention relates to a control device and method, in particular to an engine vibration reduction control device and method. Background technique [0002] Generally, the engine is usually accompanied by strong vibration when it is running, and most of the current vibration reduction methods are achieved by adding passive components to the engine, such as adding a vibration-damping frame, a vibration-damping rod or a vibration-damping rubber block, etc., but In addition to the increase of the manufacturing cost and the weight of the car body, the above-mentioned method will also cause wear and tear of the passive components and must be repaired and replaced, causing inconvenience and burden to the car owner. [0003] In recent years, with the rising awareness of environmental protection, the development of hybrid electric vehicles (or composite electric vehicles) has gradually gained attention. The hybrid vehicle uses more than one power source, and...
