Abstract (en)
[origin: WO2007147994A1] The method generates, by means of an actuator (1), a counter vibration (CV) to reduce or cancel the original vibrations and noises (V) at a given point in the cabin of the vehicle termed the control point (Pc), - the power plant itself is used as a source of a reference signal (Sr). This reference signal (Sr) is filtered into a vibrational control signal (S), which is sent to said actuator (1) to emit the counter vibration (CV) and a computer (2) is used to calculate the filter coefficients which are constant rather than the result of real-time calculations which would prove too expensive in terms of memory size and computer processing capability. - Motor vehicles. Vibration-proofing and noise-proofing control of vehicle engines.
