Abstract: An active noise control system prevents a continuous muffled sound from being generated as an abnormal sound under a high sound pressure from a speaker when a microphone as a sound detector is covered, and reduces noise immediately when the microphone is uncovered. A first threshold value as an upper limit value and a second threshold value as a lower limit value are provided for the filter coefficient of an adaptive notch filter. When the filter coefficient is greater than the first threshold value, a control sound is faded out according to a forgetting process. When the filter coefficient is smaller than the second threshold value, an adaptive control process is resumed. Even if the microphone is covered, the filter coefficient does not exceed the first threshold value as the upper limit value.

Abstract: An ANC apparatus using so-called adaptive control is provided with a cancellation sound output means which outputs front wheel cancellation sound that cancels front wheel vibration noise due to front wheel vibration at a position to be silenced on the basis of a front wheel reference signal, and outputs rear wheel cancellation sound that cancels rear wheel vibration noise due to predicted rear wheel vibration at the position to be silenced on the basis of a rear wheel reference signal, and a turning state detection means which detects a turning state of a vehicle. When a difference in travel trajectory between a front wheel and a rear wheel is detected on the basis of the turning state, the cancellation sound output means suppresses the output of the rear wheel cancellation sound.

Abstract: A frequency detecting circuit estimates the frequency fp of a propeller shaft based on the frequency fc of vehicle speed pulses, and calculates a control frequency fp′ which is a harmonic of the frequency fp. A basic signal generator generates a basic cosine wave signal xp1 and a basic sine wave signal xp2 of the control frequency fp′. Adaptive filters and an adder generate a control signal Scp for canceling a driveline noise produced in a passenger compartment by the propeller shaft. A speaker outputs a canceling sound based on the control signal Scp into the passenger compartment.

Abstract: An active vibration/noise control device which is provided with a plurality of cancel signal generation parts for generating output signals for respectively cancelling noises generated at a plurality of vibration/noise generation sources. The effect of the suspension of either of first and second cancel signal generation parts on the other is reduced. According to the operating state of the first cancel signal generation part, the simulated transmission properties of the second cancel signal generation part are adjusted. Consequently, without regard to the operating state of the first cancel signal generation part, the noise control performance of the second cancel signal generation part can be maintained.

Abstract: A processor determines an engagement state of a clutch based on a clutch signal, which is output from a clutch switch connected to a clutch pedal. In a declutching state, the processor lowers weighting gain characteristics that serve as acoustic correcting characteristics used in a sound pressure adjuster. Therefore, even when a change of an engine rotational frequency per unit of time increases during a shift-change operation, the gain of the control signal is prevented from increasing. Accordingly, a gap between real acceleration of the vehicle and a sound effect output from a speaker can be decreased, thereby reducing the possibility that the driver and/or a passenger in the vehicle may feel a sense of strangeness relative to the sound effect.

Abstract translation: 处理器基于从连接到离合器踏板的离合器开关输出的离合器信号来确定离合器的接合状态。 在解除状态下，处理器降低用作声压调节器中使用的声学校正特性的加权增益特性。 因此，即使在变速操作期间每单位时间内的发动机转速的变化增加时，也可以防止控制信号的增益增加。 因此，可以减少车辆的实际加速度和从扬声器输出的声音效果之间的差距，从而减少车辆中的驾驶员和/或乘客相对于声音效果感到陌生感的可能性。
