    摘要: An engine control system and method is disclosed, which reduces driver's feeling of unease relating to the operation of driving a vehicle which is idle-controlled so as to reduce the exhaust gas discharge, thereby improving the driving operability. The method comprising the steps of detecting a switch of the driving mode of the vehicle from a first normal driving range to a second normal driving range different from the first normal driving range; detecting whether the engine is currently in a stopped state due to an automatic stop operation; detecting whether a brake for stopping the vehicle is currently being operated; and automatically starting the engine if it is determined that the engine is currently in a stopped state due to the automatic stop operation, and that the driving mode has been switched to the second normal driving range, and that the brake is not currently being operated.

    摘要: 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.

    摘要: The control system of the present invention is provided for a hybrid vehicle with an engine, a motor, and a power storage unit. The control system selects one of an air intake passage pressure assist mode (PB assist mode) corresponding to a partial load range of the engine and a throttle assist mode corresponding to the opening state of a throttle. The control system comprises: an assist mode determining device for determining whether the vehicle is in the PB assist mode or in the throttle assist mode, based on the opening state of a throttle; a PB assist amount determining device for determining a base assist amount in the PB assist mode, based on the rotational speed of the engine and an air intake passage pressure (PB); a throttle assist amount determining device for determining the base assist amount in the throttle assist mode, based on the rotational speed of the engine, the base assist amount including a range defined by an upper threshold value and a lower threshold value; and a throttle assist amount changer for gradually changing the assist amount determined by the throttle assist amount determining device between the upper threshold value and the lower threshold value when the vehicle runs through a partial load range to a full load range of the engine.
