no. 1 Embodiment approach

[0037] [1.1 Vehicle 10]

[0038] use figure 1 The vehicle 10 will be described. The vehicle 10 has an active anti-vibration device 16 that suppresses vibrations propagating from the engine 12 to the passenger compartment 10a via the vehicle body 14 (subframe 14S and / or main frame 14M). The vehicle 10 is an engine vehicle equipped with an engine 12 as a drive source for traveling, or a hybrid vehicle equipped with a hybrid power plant including the engine 12 and an electric motor (not shown).

[0039] The engine 12 is a multi-cylinder internal combustion engine capable of switching between an all-cylinder operating state and a cylinder-deactivated operating state. Engine 12 is fixed to subframe 14S via a plurality of ACMs 18 . In the present embodiment, a front ACM 18F (hereinafter also referred to as “ACM-Fr18F”) is arranged at the front of the engine 12, and a rear ACM 18R (hereinafter also referred to as “ACM-Rr18R”) is arranged at the rear of the engine 12 . In addition...

no. 2 Embodiment approach

[0105] The active anti-vibration device 116 according to the second embodiment is a device in which a further function, that is, a failure detection function, is added to the active anti-vibration device 16 according to the first embodiment. In the second embodiment, description will be given centering on the configurations and functions that are different from those of the first embodiment, and descriptions about configurations and functions that are the same as those in the first embodiment will be omitted.

[0106] [2.1 Structure of the active anti-vibration device 116]

[0107] use Figure 9 The configuration of the active vibration isolator 116 according to the second embodiment will be described. Active anti-vibration device 116 includes ACM-ECU 140 instead of ACM-ECU 40 according to the first embodiment, and further includes auxiliary equipment ECU 118 that controls auxiliary equipment (not shown).

[0108] Auxiliary equipment ECU 118 is a computer including a microco...

Abstract

The present invention provides an active vibration damping device. An ACM-ECU executes the amplitude variable-phase variable control for variably controlling both the amplitude and the phase of activevibrations generated by an actuator according to the rotation information, in the case that an engagement rate Lr detected by an LC engagement rate detecting function is greater than or equal to a predetermined engagement rate Lr_th.

Description

technical field [0001] The present invention relates to an active anti-vibration device having an engine mount located between a multicylinder internal combustion engine mounted on a vehicle and a vehicle body, Vibration transmission from the internal combustion engine side to the vehicle body side is suppressed by active vibration generated by the actuator of the engine mount. Background technique [0002] Vibrations generated by the internal combustion engine (hereinafter also referred to as "engine") are propagated to the vehicle compartment via the vehicle body (sub frame and / or main frame). The path through which vibration propagates from the engine to the vehicle compartment roughly includes a path from the engine to the vehicle body via the engine mount (hereinafter referred to as a "suspension system path"), and a path from the output shaft of the engine to the vehicle body via the suspension or the like. path (hereinafter referred to as "drive system path"). [00...
