Title:
HYBRID AUTOMOBILE
Document Type and Number:
Japanese Patent JP2019093890
Kind Code:
A
Abstract:
To sufficiently secure a sustainable range of acceleration-feeling performance control while suppressing a decrease in charge ratio of a battery.SOLUTION: In a case where an acceleration travel is requested, acceleration-feeling performance control is executed to increase an engine revolution speed from an initial revolution speed that is lower than an engine revolution speed that efficiently outputs vehicular requirement power from the engine, with a shortage in the engine power supplemented by an output from a motor on the basis of battery power. In the case of an acceleration travel being requested when a forced charging is engaged or when a forced charging is predicted in the midst of the acceleration-feeling performance control being executed, initial discharge power to be discharged from the battery in an earlier period of the acceleration-feeling performance control is set by a reverse calculation using, as basis, battery charging power (forced charging power Pbchg) that is predicted in a convergence period of the acceleration-feeling performance control, and an initial revolution speed is set so that differential power between travel-requiring power Pd* and initial discharging power is output from the engine, thus executing the acceleration-feeling performance control.SELECTED DRAWING: Figure 5
