Abstract:
An electronic control throttle body has a default mechanism for securing the self-propelling of a vehicle at the time of faulty. A throttle control unit controls the position of a throttle valve by using a motor on the basis of a target throttle valve opening degree obtained by an engine control unit. In this respect, when the target throttle valve opening degree inputted from the engine control unit crosses over a default opening degree f0 of a default mechanism, an integration value having been added is set to 0, and an integration value having been calculated hereinafter is added to the set value to thereby perform a feedback control.
Abstract:
A throttle valve control apparatus of an engine is constructed so that the poorer the response of the throttle valve, the larger the value of a control signal given as a control signal for opening of the throttle valve, whereby the speediness of control and response of the throttle valve are improved. The engine throttle valve control apparatus has means for comparing a target opening which is a control target of the throttle valve and a real opening which obtained by a sensor or the like, and obtaining a corrected target opening of the throttle valve by a map or computing, corresponding to a difference obtained as the result of the comparison.

Abstract:
A method is provided for easily avoiding undesirable effects on various physical values due to the change in temperature of a motor for driving a throttle valve without causing secondary problems. A technique is also provided for measuring the temperature of the motor electrically. The method uses a compensation device for correcting the power supply to the motor by detecting the impedance of the motor windings and/or the change in the motor temperature. The temperature of the motor is estimated from the current and voltage to the motor.
Abstract:
A throttle control apparatus for an engine on a vehicle is provided, in which the number of component parts in the position detection means and the driven means is reduced to improve the accuracy in its position control and at the same time an integrated wiring is achieved and connectors are aggregated. The position detection means for detecting the position of a control valve, the driven means for controlling the position of the control valve, the means for processing control signals, an output from the position control means for controlling the position of the control valve are disposed within a sealed space defined by a body supporting a control valve shaft, and a cover. Based on the fact that the number of component parts of the position detection means may be reduced, the mechanical hysteresis and electrical hysteresis may also be reduced to improve the accuracy in controlling the control valve position, and it is possible to aggregate the connectors.
