The drive control method has a setting element determining the power delivered by the drive. It is controlled in dependence on a filtered power signal provided by an operating element. The filtering ensures that the variation in the power signal lies withi...

Method involves generating a value for the weight of air flow across a butterfly valve (8) as a function of the amount pumped and with a transfer function (22) inverse to the transfer function of the inlet manifold (23) downstream of the valve. The positio...

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 ...

An electronic throttle control system performs open-loop control on a motor (5) of an electronic throttle (1) by pulse width modulation (PWM) control based on a target opening amount TAR set by an accelerator sensor (8). A microcomputer (11) controls the c...

The engine is operated in two different modes of operation. Driver demand for the engine is determined by position of a pedal. Determination of the demand takes into account at least one moment differential between actual moment loss and min. moment loss. ...

An electronic throttle control system including a throttle valve for adjusting the amount of air drawn into the engine is disclosed. The throttle valve is controlled by a throttle position feedback controller which is adapted to suspend an integration elem...

A direct-fuel-injection-type internal combustion engine (10) is equipped with an injector (14) for injecting fuel directly into a combustion chamber (11) of a cylinder. A controller (30) controls the degree of opening of a throttle valve (16) for adjusting...

A method for generating a pedal output signal of an accelerator pedal for electronic throttle control is proposed, wherein a variation in the pedal output signal is produced by a displacement of the accelerator pedal. According to the method, under given c...

An electronic throttle control system is described where a throttle position sensor has multiple slopes depending on the operating region. At low throttle positions, a greater slope, and thus a greater sensitivity is provided, thereby increasing control re...
