    摘要: A travel control device for a hybrid vehicle includes: an acceleration control part for controlling a traveling motor generator or an engine based on a depression amount of an accelerator pedal; and a regenerative control part for controlling the traveling motor generator with a regenerative control intensity set by an operation part. The acceleration control part includes: an EV priority control portion for prioritizing EV traveling over engine traveling. The regenerative control part includes: a restriction portion for restricting or prohibiting regenerative braking; and a forced regeneration portion for performing regenerative braking on a driving wheel and rotationally driving a power generation motor generator by electricity generated in the traveling motor generator to rotationally drive an engine, if the regenerative braking intensity is increased by the operation part in a state where the restriction portion restricts or prohibits the regenerative braking. The acceleration control part deselects an EV priority mode if the regenerative braking intensity is increased by the operation part in a state where the EV priority mode is selected and acceptance of electricity to the driving battery is restricted.

    摘要: A hybrid vehicle comprises a power generation first motor generator (1) driven by an internal combustion engine (2), and a travel second motor generator (4) driven by a battery (5). An S mode, an ECO mode and a NORMAL mode, which are basic travel modes, are switched between using a mode change switch (16). In the S mode and the ECO mode, a deceleration rate of regenerative braking on downhill roads is large, and an amount of regeneration is large. When a downhill road on a travel route has been predicted, in the S mode and the ECO mode, a controller (6) executes an SOC reduction control in which an SOC is reduced in advance before a downhill road starts, and in the NORMAL mode, the controller (6) does not execute the SOC reduction control.
