Title:
CONTROL DEVICE OF HYBRID ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2023177952
Kind Code:
A
Abstract:
To provide a control device of a hybrid electric vehicle configured to suppress NOx purification capability of an exhaust gas purifying catalyst from decreasing while suppressing a battery from deteriorating when stopping an engine.SOLUTION: A control device of a hybrid electric vehicle is applied to a hybrid electric vehicle which is provided with an internal combustion engine including a fuel jet device and a throttle valve arranged on an air-intake passage and a power generator that can generate electric power by power of the internal combustion engine. The control device executes fuel cutoff for stopping supply of fuel from the fuel jet device and full-open control of bringing the throttle valve into a full-open state, when stopping the internal combustion engine; and executes full-close control of bringing the throttle valve into a full-close state and application control of applying power-generation loads by the power generator to the internal combustion engine, after an exhaust air-fuel ratio is made into a lean state, in a course of stopping an engine after executing the full-open control.SELECTED DRAWING: Figure 2
