  • Publication number: 20190176800
    Abstract: In a control system for an internal combustion engine which stops the rotation of an internal combustion engine by applying a counter torque thereto, the generation of noise or vibration accompanying the stop of rotation of the internal combustion engine is suppressed as much as possible. In the control system provided with a controller being adapted to stop the rotation of the internal combustion engine by carrying out forced stop processing in which the counter torque is inputted, in cases where the forced stop processing is carried out after the completion of the execution of specific motoring processing, the controller makes the counter torque at a certain timing before the counter torque becomes a predetermined torque after the start of the execution of the forced stop processing smaller than in the case where the forced stop processing is carried out without carrying out the specific motoring processing.

  • Publication number: 20180340481
    Abstract: A vehicle includes an internal combustion engine including an exhaust passage, a catalyst provided in the exhaust passage, and an electronic control unit. When the engine stop condition is established, the electronic control unit stops fuel injection and increases a catalyst inflow oxygen amount that is an amount of oxygen flowing into the catalyst by a specified oxygen increase amount. The engine stop condition is a condition for stopping operation of the internal combustion engine. The specified oxygen increase amount is larger than an increased part of the catalyst inflow oxygen amount that is increased by the stop of the fuel injection.

  • Publication number: 20180202385
    Abstract: A direct injection injector injects all of fuel having an idle required fuel amount required for an idle operation and makes a port injection injector inject no fuel from a second time to a third time so that an internal combustion engine executes idle operation from second time to third time. A fuel cut operation in which the fuel is not injected from both the direct injection injector and the port injection injector is executed from third time so that operation of the internal combustion engine is stopped at or after third time. At least one of the direct injection injector and the port injection injector inject the fuel so that operation of the internal combustion engine is restarted when a predetermined engine restart condition is satisfied under a state where operation of the internal combustion engine is stopped at or after third time.

  • Patent number: 9522670
    Abstract: A control system is provided in a vehicle including an internal combustion engine, a second MG, and a first MG. The control system starts the engine when required vehicle output becomes equal to or larger than a predetermined start threshold value, and stops the engine when the required vehicle output becomes equal to or smaller than a predetermined stop threshold value. The control system controls the engine so that output power equal to or larger than a predetermined output lower-limit value is generated, during a period from the time when the required vehicle output becomes equal to or larger than the predetermined start threshold value to the time when the required vehicle output becomes equal to or lower than the predetermined stop threshold value. The predetermined output lower-limit value is set to the predetermined start threshold value used when the required vehicle output becomes equal to or larger than the predetermined start threshold value.
