摘要:
A fault diagnosis apparatus for sensors in an apparatus system has at least three sensors which detect different physical quantities for one physical phenomenon which vary in correlation with one another, the sensors outputting signals indicating the detected physical quantities, wherein outputs from the at least three sensors are converted into one identical physical quantity in accordance with the correlations so that the resulting identical physical quantity can be used to determine whether or not each of the sensors is defective.

An object of the invention is to provide a vehicle control apparatus which can achieve a smooth start without generating any engine stall even if general drivers perform a rough starting operation in an MT vehicle, and can execute an engine torque operation having no sense of discomfort with respect to an accelerator operation. A rotating speed drop of an engine generated together with a clutch connection is detected so as to be set to a trigger of a control start, an engine rotating speed at a time of issuing the trigger is set to a target rotating speed, and a rotating speed feedback control having an engine torque as an operation amount is carried out. As an operating means for the engine torque, an ignition retard and a fuel cut are employed in addition to an intake air amount operation by an electronically controlled throttle. It is possible to achieve a just enough torque assist for minimizing a drop of the engine rotating speed at a time of connecting the clutch, by applying the rotating speed feedback control.

A noise eliminating filter is incorporated in the circuits of electronic equipment to eliminate unwanted signals by grounding such signals. The filter includes a tubular metal casing, capacitors and a magnetic material housed within the casing, and a terminal passing through the capacitors and magnetic material. Capacitor housings are provided at both axial ends of the metal casing. A magnetic material housing which is smaller in diameter than each capacitor housing is formed between the capacitor housings and a feedthrough terminal is inserted through the capacitors contained in both the capacitor housings and the magnetic material contained in the magnetic material housing. The capacitors, which are to be incorporated in the housings at both end portions of the casing are made tubular and equal in diameter, thereby enabling the metal casing to be compact and enabling the capacitors to be standardized.
