摘要： When the remaining capacity of a battery on a hybrid vehicle is smaller than a threshold value or the battery is unable to output the amount of electric energy required to propel the hybrid vehicle with a propulsive electric motor, the engine is started by a generator which operates in a motor mode. After the engine has been warmed up, the generator operates in a generator mode to generate electric energy which is supplied to the battery and the propulsive electric motor. The threshold value for the remaining capacity of the battery is greater as the atmospheric pressure is lower. Therefore, if the hybrid vehicle is running under a low atmospheric pressure such as on a highland, the electric energy is supplied from the generator to the battery and the propulsive electric motor at an early stage where the capacity of the battery is relatively high. The generator also starts to generate electric energy when the battery is unable to output an amount of electric energy sufficient enough to propel the hybrid vehicle.

摘要： When the engine RPM falls below a lower limit of a target RPM of idling while an engine is in an idle operation, a control valve is shifted to the open-loop control mode instead of the conventional feedback control mode so as to enable the engine RPM range to be quickly increased up to within the target RPM of idling rotations. Said control valve is disposed in a bypass which communicates with the upstream side and the downstream side of the throttle valve in intake passage to adjust the volume of an inspired air. The solenoid current command (amount of control) for adjusting the opening degree of the control valve during the period of the open-loop control mode is set at a level higher than that immediately before the feedback control mode shifts to the open-loop control mode.

摘要： Feedback control of the opening area of a bypass which is provided in parallel with a throttle valve of an engine is conducted immediately after the cranking is completed, based on the deviation of existing RPM from the target RPM which is memorized as the function of the engine temperature in advance, to maintain the idling RPM of the engine at optimum level in the state of after-cranking without being affected by the possible change in viscosity of engine oil, the variations in temperatures of the ambient air and the engine cooling water, the load of engine, and so on. The control signals for the feedback control are learned when the existing RPM are substantially equal to the target RPM and stored in a memory. One of the learned values is read out for fixing a control signal in the beginning of the state of after-cranking so that the RPM of the engine is smoothly approximated to the target RPM when the engine shifts from the during-cranking state to the idling state.

摘要： An intake air quantity control method for an internal combustion engine at idle. A supplementary air quantity to be supplied to the engine through a first auxiliary air passage bypassing an engine throttle valve is controlled by a first control valve on the basis of a basic value of a control amount corresponding to the difference between actual engine speed and desired idling speed. A supplementary air quantity to be supplied to the engine through a second auxiliary air passage is controlled by a second control valve in response to engine temperature. A first correction value is calculated based upon detected atmospheric pressure encompassing the engine, and a second correction value based upon detected engine temperature and atmospheric pressure, respectively. The basic value of the control amount is corrected by means of the first and second correction values, and the first control valve is driven according to the corrected control amount basic value. Preferably, the second correction value is calculated from a value of the control amount corresponding to a supplementary air quantity estimated to be supplied through the second control valve at the detected engine temperature and from the first correction value based upon the detected atmospheric pressure.

摘要： A method for controlling air-fuel ratio of the mixture to be supplied to the engine detects whether or not the amount of the fuel to be supplied to the engine is greater than a reference amount. A feedback control in which the air-fuel ratio is corrected according to an oxygen concentration in the exhaust gas is performed when the amount of the fuel to be supplied to the engine is equal to or smaller than the reference level, while an open loop control in which the air-fuel ratio of the mixture is determined irrespective of the oxygen concentration is performed if the amount of the fuel to be supplied to the engine is greater than the reference level. The reference amount is changed depending on the engine rotational speed so as to eliminate the overlap of a range of the fuel increment control and a range of the feedback control and greatly improve the driveability of the engine during high load operating conditions of the engine.
