Control device of hybrid system

摘要

The invention relates to a control device of a hybrid system. The control device selectively performs first and second modes for concomitantly using an EV mode for operating the electric motor (12) with the engine operation being stopped and an HV mode for selectively operating the engine and stopping the engine operation with the electric motor being operated by switching the EV and HV modes according to a predetermined switching condition set such that a proportion of an engine operation time in the first mode is smaller than that in the second mode. When an actual acceleration pedal manipulation amount is smaller than a first manipulation amount, an amount of the hybrid system power increased according to the increasing of the actual acceleration pedal manipulation amount in the first mode is made larger than that in the second mode.

主权项

1. A control device of a hybrid system comprising:
an internal combustion engine; and an electric motor, the hybrid system can output a power output from the engine by operation of the engine and a power output from the electric motor by operation of the electric motor selectively or simultaneously, the control device comprising an electronic control unit programmed to selectively perform first and second modes for concomitantly using an EV mode for performing the operation of the electric motor while stopping the operation of the engine and an HV mode for selectively performing the operation of the engine and stop of the operation of the engine while operating the electric motor by switching the EV mode and the HV mode according to a predetermined switching condition set such that a proportion of an operation time of the engine occupying a total time of the first mode is smaller than a proportion of the operation time of the engine occupying a total time of the second mode, wherein the electronic control unit is programmed to control an increase amount of a power output from the hybrid system relative to an increase amount of an actual acceleration pedal manipulation amount such that the increase amount of the power output from the hybrid system relative to the increase amount of the actual acceleration pedal manipulation amount when the first mode is selected and the actual acceleration pedal manipulation amount is smaller than a predetermined first manipulation amount, is larger than the increase amount of the power output from the hybrid system relative to the increase amount of the actual acceleration pedal manipulation amount when the second mode is selected and the actual acceleration pedal manipulation amount is smaller than the predetermined first manipulation amount.
