Abstract: Normally, a phase fixed control is executed. In the event that a vibration value VAPP of an engine becomes greater than or equal to a predetermined vibration value VAPP_th, a first phase of an active vibration generated by a first actuator and a second phase of an active vibration generated by a second actuator are changed in mutually opposite directions.

Abstract: An ACM-ECU executes an amplitude variable-phase variable control for variably controlling both the amplitude and phase of active vibrations generated by an actuator according to 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.

Abstract: In the case that an all-cylinder operational state is detected by an ENG vibration pattern determining function, an ACM-ECU executes an amplitude variable—phase fixed control. Further, in the case that a cylinder paused operational state is detected by the ENG vibration pattern determining function, the ACM-ECU executes an amplitude variable—phase variable control exhibiting a large vibration damping effect.

Abstract: A control apparatus includes an actuator ECU for controlling a plurality of ACMs. When an engine is started or restarted, the actuator ECU begins a vibration suppressing control process with the ACMs for suppressing vibrations transmitted to a vehicle body when a crankshaft angle, which is represented by a CRK pulse signal from a CRK sensor, reaches a beginning crankshaft angle.

Abstract: Provided are: an engine-mounted controller capable of being suitably used in a vehicle that carries out an idle-stop operation while the vehicle is moving; and a vehicle. An engine-mounted controller of a vehicle determines whether or not an engine is in a completely stopped state when an idle-stop operation is canceled. If the controller determines that the engine is in a completely stopped state, a first control operation for suppressing the transmission of engine vibrations associated with engine idling is executed on the assumption that the engine is in a completely stopped state, and if the controller determines that the engine is not in a completely stopped state, the first control operation is prohibited when the engine restarts.

Abstract: A control apparatus for controlling a vehicle includes an actuator ECU. The actuator ECU acquires a crankshaft angle (stopped crankshaft angle) at a time that an engine stops operating. The actuator ECU identifies a crankshaft angle depending on an edge of a first TDC pulse of a TDC pulse signal immediately after the engine has been started or restarted. Then, using the identified crankshaft angle as a reference, the actuator ECU corrects the stopped crankshaft angle.
