Abstract:
1. An active anti-vibration supporting device that supports an engine with respect to a vehicle body, comprising: a sensor for detecting rotation variation of the engine; an actuator; and a control unit for estimating a vibration state of the engine and for expandingly or contractingly driving the actuator to reduce transmission of vibration based on output from the sensor, wherein the control unit: computes a target current value waveform for reducing transmission of vibration of the engine, using output data from the sensor, and obtains a data group of target current values from the target current value waveform in a predetermined sampling cycle; estimates a cycle length of the engine vibration, based on a certain time defined by a rotation speed of the engine at a drive timing of the actuator driven based on the target current value waveform; corrects a number of data pieces included in the obtained data group of target current values so that the data group of target current values comes to correspond to the estimated cycle length of the engine vibrations and then supply current to the actuator, wherein the correction effected by the control unit is based on a position of data of a target current value, in the data group of target current values, that is output at a predetermined timing based on a signal from the sensor, such that the control unit adjusts a number of data pieces of a data portion having not yet been output of the data group of target current values which are being output so that the number of data pieces comes to correspond to a then present cycle length of the engine vibration.
