摘要： In an actuator drive control device for an active vibration isolation support system, accumulated time of eight time intervals tn of crank pulses which are outputted at every 15 degrees of a crank angle in a vibration period corresponding to 120 degrees of the crank angle, and average accumulated time shown by a straight line connecting a start point and an end point of the line of the accumulated time are calculated. Eight deviations Δtn are calculated by subtracting the average accumulated time from the accumulated time. A variation waveform of the deviations Δtn corresponds to a variation waveform of the time interval tn of the crank pulses attributable only to the engine vibration with the influence of a variation in the engine rotational speed Ne being eliminated. Therefore, the vibration isolation function of an active vibration isolation support system can be effectively executed by controlling an actuator of the active vibration isolation support system based on the engine vibration which is estimated from the variation waveform of the time interval tn. Thus, the active vibration isolation support system is precisely controlled by accurately estimating a vibration state of the engine when the engine rotational speed increases and decreases.

摘要： When switching between L3 cylinder cut-off running in which a bank on one side of a V6 engine is cut off and V4 cylinder cut-off running in which one cylinder in each of the two banks is cut off, V6 all-cylinder running to operate all the cylinders is interposed therebetween. Therefore, a transitional period is provided between L3 cylinder cut-off running and V6 all-cylinder running and between V6 all-cylinder running and V4 cylinder cut-off running, and no transitional period is present between L3 cylinder cut-off running and V4 cylinder cut-off running. Thus, it is possible to simplify control of an active vibration isolation support system during the transitional period and to avoid deterioration of a vibrational state during the transitional period.

摘要： In an active vibration isolation support system, an actuator case is constituted by a resin member and holds an outer peripheral portion of an actuator in an upper housing and a lower housing which accommodate therein an elastic body, first and second liquid chambers, a movable member, and the actuator. The plastic actuator case is easily broken by an impact applied thereto upon collision, thereby easily breaking the upper housing apart from the lower housing. Therefore, an engine can move with respect to a vehicle body frame, thereby securing a clash stroke. Also, as compared with the case where the actuator case is constituted by an iron-based member, weight of the active vibration isolation support system is reduced.

摘要： An active vibration isolation support system, supplies current to a coil of an actuator according to the vibrational state of an engine, so that the actuator moves out and back a movable member to which an elastic body is connected. The elastic body is then deformed to change the capacity of a liquid chamber, thereby exerting vibration isolation function. Even if the pressure in a sealed internal space of an actuator case is changed due to the moving out and back of the movable member, the current is variably supplied to the coil of the actuator according to such a change in the pressure of the internal space, thereby controlling the thrust of the movable member so as to be constant. Therefore, the movable member is appropriately driven without receiving the influence of the change of the pressure in the sealed internal space of the actuator case, thereby exerting full performance of the active vibration isolation support system.

摘要： In an active vibration isolation support system, a movable member is connected to an armature (movable core) of an actuator and moved out and back by the armature, the armature is housed in a sealed space, and a pressure of the sealed space is maintained at substantially atmospheric pressure by a flexible bag that is disposed within the sealed space and communicates with the atmosphere via a through hole formed in a wall defining the sealed space. Therefore, while preventing dust and water from entering the sealed space to prevent malfunction of the armature, a change of pressure is prevented in the sealed space to maintain a neutral position of the movable member, thereby controlling vibration of the movable member with a good precision.

摘要： An actuator of an active engine vibration isolation support system is driven based on the first, second, third . . . duty groups calculated corresponding to the vibration periods t1, t2, t3 . . . of the engine. When the engine rotational speed varies in the increasing direction and the vibration periods t1, t2, t3 . . . become gradually shorter, parts of the first, second, third . . . duty groups overlap each other, and therefore an electrical current which is supplied to the actuator does not become 0 at the end of the duty groups, leading to a possibility that a peak value of the electrical current gradually increases so that not only the active vibration isolation support system cannot exhibit an effective vibration isolation function, but also the actuator generates heat. Therefore, for example, when the overlapping amount of the first and the second duty groups exceeds a threshold value, a duty ratio of the second duty group is made 0 to stop application of the electrical current to the actuator. Thus, the vibration isolation function of the active vibration isolation support system is prevented from being impaired by the variation in the frequency of the input vibration.
