Description
Technical field
The present invention relates to reduce the equipment and the method for the vibration of explosive motor with at least one active vibration damper (active vibrationdamper), this active vibration damper activates by control signal, so that the vibration of explosive motor is reduced or eliminates, described control signal is based on that the survey data of at least one sensor obtains, and this survey data is related with the vibration of explosive motor.
Background technique
The equipment of active vibration damper type can be understood from DE 102004062471B3.In this system, the control signal of active vibration damper is based on that the synchronization signal of crankshaft rotating rate signal and crank phase obtains.
This kind equipment also can be understood from DE 19842729C1.In this system, the control signal of active vibration damper is based on that top dead center (top dead center) sensor obtains.
Vibration insulating system is used for explosive motor or its transmission component, as Power Train, so that reduce undesirable noise and other phenomenons that are commonly called NVH (noise, vibration and cacophony shake) in the Motor Vehicle.
Motor driving or electromagnetism or hydraulic actuator are used as the active vibration damper, and this actuator utilizes open loop or closed loop control system to activate, and its mode is to excite explosive motor or transmission component anti-phase so that reduce or eliminate its vibration.Actuator with piezoelectric effect work also can be used as vibration damper.
The target of good NVH system should be the mechanical vibration that minimize motor half order harmonics (enginehalf-order), motor half order harmonics is understood that to refer to unbalanced force or the momentum on the explosive motor, and per two the axle period of rotation ground of unbalanced force or momentum change once.Thereby order harmonics is corresponding to the rotational speed of explosive motor.The synchronism that under this background, also refers to explosive motor.Motor half order harmonics is derived from unbalanced in each cylinder (unequal) combustion characteristic curve, and reaches minimum in the process of optimizing the cylinder synchronism relative to each other.The unbalanced burning of each cylinder can be caused by each assembly that occurs during manufacture and the dispersion of actuator.
Above-mentioned known system is from crankshaft rotating speed and crank phase or obtain the control signal of active vibration damper from top dead center, therefore only the frequency of motor order harmonics self can effectively be compensated more or less, but the frequency of motor half order harmonics is not compensated yet or may only be similar to compensation.
The further shortcoming of known system is that TDCS TDC Sensor only produces top dead center, but not the measurement of the actual vibration that takes place of reproduction, and any control signal of active vibration damper can obtain from crankshaft rotating speed and crank phase, for example, unavoidable delay is only arranged.Therefore, can not obtain and let alone the quick variation of vibrational state of compensation explosive motor, this quick variation may occur in the idle running process, for example from rev to another time revolution or even in directly continuously the igniting of each separate cylinders.

Because except the control signal of active vibration damper, controlling the further control signal of burning in one or more cylinder obtains based on the survey data of the state of ongoing burning in the cylinder of explosive motor, so the present invention can be advantageously replenished by these further signals or with these further signal combination, thereby obtain automatic combustion control system.
Though for example the maximum value of sensor signals such as pressure in the cylinder or temperature is represented the main cause of engine luggine, be press in the so-called maximum in-cylinder or with its proportional substantially temperature, and the maximum value of described sensor signal immediately and suitably proportional with the frequency of common overriding motor half order harmonics, yet the vibration of the actual generation of explosive motor specific components or transmission component may be not proportional with it.
Accordingly, in a preferred embodiment, in instant detection explosive motor cylinder, the sensor of the state of ongoing burning, also provide at least one the further sensor that detects the vibration of one of explosive motor or its assembly.For example, the form of this further sensor is the noise transducer (as detonation sensor) of structurally associated and/or detects the high resolution sensor that angular velocity of crankshaft changes, can determine the torsional vibration of bent axle by this sensor.
Survey data by the joint assessment combustion regime and by the survey data of one of the vibration of internal combustion engine of further sensor or its assembly, the control signal of active vibration damper can be obtained to be used for, the vibration of explosive motor or its assembly can be reduced by this control signal best.
The control signal of controlling the burning in one or more cylinder is preferably equally and obtains by the survey data of combustion regime and the joint assessment of the survey data of the vibration that utilizes further sensor.
The control signal of the control signal of active vibration damper and burning control is the survey data acquisition of the survey data by the state of ongoing burning in the related explosive motor cylinder and at least one further sensor preferably.The combination of the survey data of instant available combustion regime and the actual but vibration measurement data that postpone and preferably relatedly allow to calculate reliably predicted value, compare with the traditional combustion control system, utilize this predicted value can be by suitably activating the active vibration damper to offset subsequently vibration effectively, and allow improved burning control extraly.
The active vibration damper preferably utilizes control signal to activate, so that make the common overriding vibration of motor half order harmonics be reduced or eliminate especially.Especially, the survey data of the survey data of the state of ongoing burning and at least one further sensor and the level that thus obtained predicted value can be used to calculation engine half order harmonics in the explosive motor cylinder, thereby the level and the reference value of comparison engine half order harmonics, if and the level of motor half order harmonics is more than reference value, then change the control signal of active vibration damper, up to the level of motor half order harmonics below reference value.
By this way, idling vibration in each separate cylinders and combustion noise can fully be reduced especially.Such vibration and noise are easy to take place in the explosive motor of ignition by compression especially, as have the diesel engine of pressing in the higher maximum in-cylinder.
If explosive motor is a multicylinder engine, then according to a preferred embodiment of the invention, for each cylinder provides sensor, cylinder pressure transducer for example, this sensor provides the survey data of the state of ongoing burning in the instant reproduction explosive motor cylinder.By this way, each independently the vibrational energy that causes of cylinder effectively offset.This quick change to engine condition is particularly useful, and for example in the opposite conversion of the neutralization of the conversion from the travelling state to the idling conditions, this can not appropriately be managed under the situation of no suitable survey data by traditional vibrate in opposite phase damping.
In the common current motor vehicle that all occur in any case of all the sensors, actuator and the electronic device of the software-controllable system that the improvement of the present invention of stipulating in enforcement the present invention or the dependent claims is required, therefore all embodiments of the present invention all can implement with low-down complexity and cost.
