HYBRID VEHICLE AND CONTROL METHOD FOR HYBRID VEHICLE

摘要

A hybrid vehicle includes an engine, an exhaust passage, a filter, an electrical storage device, a driving apparatus and an ECU. The exhaust passage is connected to the engine. The filter is configured to trap particulate matter flowing through the exhaust passage. The electrical storage device is configured to be charged when the engine is in operation. The driving apparatus is configured to generate a driving force of the hybrid vehicle by using an electric power of the electrical storage device. The ECU is configured to control a charge/discharge amount of the electrical storage device such that a state of charge of the electrical storage device falls within a control range. The ECU is configured to expand the control range such that the control range at the time when regeneration of the filter is required is wider than the control range at the time when regeneration of the filter is not required, reduce the state of charge toward a lower limit value of the control range, and then increase the state of charge toward an upper limit value of the control range.
