Abstract: An engine idling control device includes a secondary air supply device, an intake gauge pressure detecting unit and a secondary air supply control unit. The secondary air supply device is disposed on a bypass intake passage communicating with an intake pipe and bypassing a throttle valve. The intake gauge pressure detecting unit detects an intake gauge pressure on the intake pipe side. The secondary air supply control unit controls the secondary air supply device so as to open and close the bypass intake passage when an engine is in an idling state. The secondary air supply device is controlled to obtain the optional opening value. The secondary air supply control unit controls such that the secondary air supply device increases the opening value when the intake gauge pressure becomes higher than a predetermined low load condition in an idling state.

Abstract: In order to prevent an occurrence of dieseling phenomenon, and to prevent engine rotation speed from decreasing during idle operation or the idle operation from being stopped, in step S111, it is determined whether the flag value of an idle stop flag F_IDLSTP is “1” or not. If it is determined that the determination result is “YES”, that is, if it is determined that the internal combustion engine body is stopped, 0% is set to a target purge control valve drive duty value PGCMD (step S105), and 0 is set to the target purge flow rate QPGC (step S106). If it is determined that the determination result is “NO”, that is, when the internal combustion engine body is in operation, PGCMD calculation processing is executed (step S112). While the internal combustion engine body is stopped, execution of purge is stopped, thereby an occurrence of a dieseling phenomenon which is caused because the flow rate of the air flowing into the internal combustion engine body increases and the air is compressed, is prevented, thereby suppressing vibration from occurring in the internal combustion engine body.

Abstract: The present invention increases the frequency of the LAF sensor deterioration determination in the case that air-fuel ratio control is being carried out while the deterioration of the LAF sensor is being monitored. When the monitor conditions are no longer satisfied during the deterioration determination of the LAF sensor (as shown in (a) and (b) of FIG. 6), the LAF prohibition timer is operated (as shown in (c) of FIG. 6), and switching to a lean burn is prohibited for a predetermined time interval (for example, 7 seconds), and in addition, after the LAF sensor deterioration determination has completed, after passage of a time interval shorter than this predetermined time interval (for example, 2 seconds) (as shown in figures (c) and (d) of FIG. 6), a lean burn is permitted. Thereby, in the case that monitor conditions are no longer satisfied during monitoring, because the lean burn is prohibited, unlike conventional technology, there is no immediate switch to a lean burn, and therefore, the frequency of the deterioration determination of the LAF sensor can be increased.

Abstract: In vehicle operation under cruise mode, the battery, which is in a low temperature state, is caused to rise in temperature at an early stage, and the assistance amount and the regeneration power generation amount by means of the motor are caused to increase. During vehicle operation in cruise mode, in the case in which one or the other of the battery temperature and the engine water temperature have failed to reach a predetermined temperature, the cruise power generation amount is raised to a predetermined level, and charging of the battery is continued until both the battery temperature and the engine water temperature have reached predetermined temperatures. When a determination has been made that there is no further room in the battery to accept further charge, power generation and assistance is conducted by the motor so as to cancel periodic fluctuations in the drive force of the engine, and vibration damping control is conducted for suppressing vibrations generated by the engine in accordance with the fluctuations in the drive force of the engine.
