摘要:
A viscous heater for heating cooling water for cooling a water cooled engine is provided in a cooling water circuit between the engine and a front heater core. Even if a viscous switch is turned on by a viscous ECU to heat a passenger compartment using the viscous heater, a viscous clutch is not immediately turned on when the engine is idling. That is, after a delay control time elapses after increasing an idling rotational speed of the engine to a target rotational speed, the viscous heater is turned on. The target rotational speed which is higher than a normal idling rotational speed is set in such a manner that the higher the cooling water temperature is, the lower the target rotational speed becomes. Thus, even if a large load is applied to the engine by operating the viscous heater when the engine is idling, it can improve fuel economy and prevent an engine stall.

摘要:
A vibratory angular rate sensor comprises a vibrator having a vibrating element arranged to oscillate along a first direction, the element being arranged to further oscillate along a second direction perpendicular to the first direction when subjected to angular rate about a third direction perpendicular to the first and second directions. The vibrating element is caused to oscillate at a predetermined frequency along the first direction. An oscillation detector generates a voltage representing oscillations of the vibrating element along the second direction. A first synchronous detector synchronously detects a primary frequency component of the generated voltage using clock pulses of the predetermined frequency to produce an output signal. A second synchronous detector synchronously detects an odd-numbered harmonic of the generated voltage using clock pulses of the odd-numbered harmonic frequency. A residual odd-numbered harmonic component contained in the output signal of the first synchronous detector is cancelled with the detected odd-numbered harmonic.

An angular velocity sensor device includes a switch (S1) for selecting a first or second driving signal mutually opposite in phase applied to driving electrodes (D1, D2) to oscillate a weight part (8) in a first direction. An adding circuit (29) adjusts the amplitude of the driving signal selected and adds it to a monitor signal reflecting the oscillating state of the weight part (8). A noise signal component appearing in the output signal of the adding circuit (29) is adjusted to a minimum and the output signal is supplied as a feedback signal to a self-oscillating circuit (27) for reducing the noise signal influence on the oscillating drive of the weight part.
