摘要： An apparatus for controlling a hybrid vehicle having an internal combustion engine and an electric motor as driving sources for the vehicle, in which when it is detected that an air-fuel ratio of a supply air-fuel mixture to the engine changed to the lean side value (S44˜S46), the electric motor (2) is made operative as a motor in order to assist an output of the engine just after the detection (S47, S48). When it is detected that the air-fuel ratio of the supply air-fuel mixture changed to the rich side value (S44, S52, S53), the electric motor (2) is made operative as a generator for the purpose of the regeneration braking just after the detection (S54, S55). An output torque difference of the engine, therefore, when the air-fuel ratio of the supply air-fuel mixture changes can be sufficiently compensated without a time delay.

摘要： An auxiliary air amount control system for an internal combustion engine has an auxiliary air passage bypassing a throttle valve arranged within the intake pipe of the engine, and a control valve controlling the amount of auxiliary air supplied to the engine through the auxiliary air passage by varying the opening of the passage. The opening of the control valve is set in response to the opening of the throttle valve, and is decreased progressively from the set value as an initial value when the engine is in a predetermined decelerating condition. The set control valve opening is varied to a larger value as the reduction ratio assumed by a transmission connected to the engine is larger. The minimum value of the throttle valve opening at which the control valve opening can be set to a value larger than zero is varied to a smaller value as the reduction ratio is larger. The rate at which the control valve opening is progressively decreased is varied to a smaller value as the reduction ratio is larger.

摘要： When the shift position is an N position or a P position during deceleration of a vehicle, or when a brake pedal is depressed even if the shift position is a D position or an R position, an engine E is stopped to prohibit an unnecessary idling operation by prohibiting the restarting of the supplying of fuel subsequent to the fuel cut by a command from an electronic control unit. If the supplying of fuel is restarted when the engine is in stoppage, a starter motor is driven automatically to start the engine. Thus, in a vehicle including an automatic transmission, the time of stoppage of the engine can be prolonged as much as possible in a range in which the operability of the vehicle is injured, thereby providing a reduction in amount of fuel consumed.

摘要： A control device for a hybrid vehicle powered from an engine and an assist motor for supplying electric power in an amount predetermined according to running conditions of the vehicle further includes means for detecting a catalyzer temperature and correcting the predetermined assist power value according to the detected catalyzer temperature when accelerating and means for preventing the idling engine from being cut off when detected catalyzer temperature is lower than a preset temperature. This control device thus realizes rapid heating of the catalyzer device to a temperature necessary for activating the catalyzer therein by adequately correcting the assist power value of the motor according to the current catalyzer temperature when accelerating and by preventing the idling engine from being cut off while the catalyzer device has a low temperature.

摘要： An abnormality detection system is provided, which detects abnormality in an evaporative fuel control system for an internal combustion engine. A plurality of temperature sensors are arranged in an evaporative fuel storage device at different locations for detecting the temperature of an adsorbent or in the vicinity thereof within the storage device at the different locations. An ECU controls at least one of charging of evaporative fuel from the fuel tank to the storage device and purging of evaporative fuel from the storage device to the intake system of the engine. The ECU determines the presence or absence of an abnormality in the evaporative fuel control system, based upon output values from the temperature sensors assumed when the control system is operative. A state in which adsorption of evaporative fuel generated in the fuel tank to the adsorbent of the storage device has been completed is detected, based upon the amount of a rise in temperature detected while the charging is being effected. The ECU effects the abnormality determination after the state has been detected. The system may be applied to an internal combustion engine in which the air-fuel ratio is controlled by the use of an air-fuel ratio correction coefficient determined in response to an output from an air-fuel ratio sensor.
