Control system for hybrid vehicle

摘要

An electronic control unit included in a control system is configured to execute a change of a combustion mode in an inertia-phase period during a gear shift operation, or after the gear shift operation is completed, when a request for the change of the combustion mode and a request for a gear shift of the transmission mechanism overlap. The electronic control unit is configured to execute the change of the combustion mode in the inertia-phase period during the gear shift operation when conditions i) and ii) are established, and execute the change of the combustion mode after the gear shift operation is completed when conditions i) and iii) are established. The aforementioned conditions include: i) the change of the combustion mode is accompanied by an increase in engine power; ii) the power running mode is executed during the gear shift operation; and iii) the regeneration mode is executed during the gear shift operation.

1. A control system for a hybrid vehicle, the hybrid vehicle including an internal combustion engine, a battery, a motor generator, and a transmission mechanism, the internal combustion engine capable of changing a combustion mode accompanied by a change of an air-fuel ratio, the motor generator electrically connected to the battery, the internal combustion engine and the motor generator provided on an input side of the transmission mechanism,
the control system comprising: an electronic control unit configured to be able to selectively execute a power running mode in which power running of the motor generator is executed by using electric power of the battery and a regeneration mode in which regeneration control is executed in the motor generator so as to charge the battery, the electronic control unit configured to execute a change of the combustion mode in an inertia-phase period during a gear shift operation or after the gear shift operation is completed where a request for the change of the combustion mode and a request for a gear shift of the transmission mechanism overlap, the electronic control unit configured to execute the change of the combustion mode in the inertia-phase period during the gear shift operation where the following conditions i) and ii) are established, and the electronic control unit configured to execute the change of the combustion mode after the gear shift operation is completed where the following conditions i) and iii) are established: i) the change of the combustion mode is accompanied by an increase in engine power; ii) the power running mode is executed during the gear shift operation; and iii) the regeneration mode is executed during the gear shift operation.
