Patent Searching and Data


Title:
VIBRATION REDUCTION DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JPH0633985
Kind Code:
A
Abstract:

PURPOSE: To enable formation of a reference signal from other than an ignition pulse signal and information on crank angles so as to increase accuracies by detecting the angle of rotation of a cam shaft, and producing a reference signal in accordance with an output signal indicating the angle.

CONSTITUTION: A means (ECU)38 for detecting the angle of rotation of a cam shaft outputs a control signal for an injection valve in accordance with an SGC signal, an SGT signal, an intake air amount signal and a water temperature signal, etc. from a distributor 44. A means 53 for detecting the period of rotation of an engine detects the period of rotation of an engine in accordance with the SGT signal and the SGC signal and inputs it to a means 55 for determining the period of reference signal, which then determines the period T of reference signal. The period T is input to a reference signal transmitter 58. The transmitter 58 determines a reference signal X on the basis of phase δand amplitude A and outputs it, the phase δ and the amplitude A being output from a means 57 for determining reference signal phase and a means 56 for determining reference signal amplitude, respectively.
