    摘要： An object is to improve fuel consumption efficiency while maintaining a desired driving force. Accordingly, in a case where an assisting possibility of a motor M is increased accompanying a relatively high state of charge SOC of a battery (YES side in step S02), and moreover in a case where a required torque TQAPCC is less than a predetermined value (NO side in step S03 or YES side in step S04), a “1” is set to a flag value of an LC_ON assistance flag F_LCOAST, and in a region for an accelerator pedal opening AP, and a vehicle speed VP, a region which maintains an LC_ON state where a lock-up clutch 21 is in an engaged state is enlarged compared to for a normal state where the flag value of the LC_ON assistance flag F_LCOAST is “0”. In the LC_ON region enlarging state, it is determined whether or not it is possible to shift to the normal state, according to the state of charge SOC and the required torque TQAPCC (step S07 to step S09).

    摘要： A control system for a variable-cylinder internal combustion engine, which is capable of attaining excellent fuel economy by executing a partial-cylinder operation mode as long as possible, while suppressing vibration and noise during the partial-cylinder operation mode. A control system switches the operation mode of a variable-cylinder internal combustion engine between an all-cylinder operation mode in which all of a plurality of cylinders (#1 to #3, and #4 to #6) are put in operation, and a partial-cylinder operation mode in which some (#1 to #3) of the plurality of cylinders are deactivated. During the partial-cylinder operation mode, the control system 1 calculates a degree-of-continuation parameter SDTQCSNH indicative of a degree of continuation of a state where detected load TQECMDF on the engine is within a predetermined range of load between a first reference value TQCSNH and a second reference value TQCSEH smaller than the first reference value (steps 10 to 13), and determines whether or not the operation mode should be switched to the all-cylinder operation mode, based on the degree-of-continuation parameter SDTQCSNH (step 14).

    摘要： There is provided a control system for a vehicle, which enables the vehicle to smoothly travel only to find a place to park when an electric throttle control device is in a condition incapable of controlling a throttle valve, thereby improving drivability. An ECU determines whether or not the electric throttle control device is in the condition incapable of controlling the throttle valve, and interrupts energization of the electric throttle control device when it is determined that the electric throttle control device is in the condition incapable of controlling the throttle valve. The throttle valve is held at a default opening position by a spring when the electric throttle control device is determined to be in the condition incapable of controlling the throttle valve. A throttle valve opening sensor detects a degree of opening of the throttle valve. The speed position of an automatic transmission is controlled to a highest speed position if the detected degree of opening of the throttle valve is equal to or smaller than a predetermined reference value when the electric throttle control device is determined to be in the condition incapable of controlling the throttle valve.

    摘要： A highly stable engine failure diagnosing system free from influence of purging is presented. A monitoring apparatus for monitoring a fuel feed system of an internal combustion engine is provided with an A/F ratio detector and an A/F ratio controller for performing feedback control of the A/F ratio. An A/F ratio feedback coefficient is calculated according to the output of the detector. A malfunction determination parameter is calculated based on the coefficient. A purging is suspended when the parameter reaches a first decision value. The monitoring is suspended when the parameter reaches a second decision value in a purge cutting state. A value of the malfunction determination parameter it would take if the purge cut was not carried out is estimated using the value when the parameter reached the first decision value. The monitoring is resumed when the estimated value of the malfunction determination parameter reaches the second decision value.

    摘要： A fuel injection control system including an ECU, for an internal combustion engine which is capable of changing a valve overlap period by changing a cam phase. The ECU calculates a cam phase difference between the present value and the immediately preceding value of the cam phase (amount of change in the valve overlap period), calculates a wall surface temperature of intake ports, and sets a basic fuel injection time period based on an intake pipe absolute pressure and an engine rotational speed. The ECU also calculates a final fuel injection time period by correcting the basic fuel injection time period according to the cam phase difference and wall surface temperature of the intake ports.
