An operation control system for a hybrid vehicle capable of causing the vehicle to travel in parallel mode in which front wheels of the vehicle are driven by an engine and a front motor, capable of fuel cut control to stop fuel supply to the engine during deceleration of the vehicle, and capable of regenerative braking using the front motor, wherein when the vehicle traveling in parallel mode is to be decelerated and SOC of a traction battery is lower than or equal to an electricity-generation determination lower limit value Sbu, Sbd, a hybrid control unit performs first charging promotion control to brake the vehicle by regenerative braking while causing the engine to continue operating by continuing fuel supply.

Operation control system for hybrid vehicle

A control device for a hybrid vehicle including an internal combustion engine includes: a limiting unit configured to limit an output of the internal combustion engine when temperature of cooling water for cooling the internal combustion engine is equal to or higher than a predetermined temperature; a discharging unit configured to discharge, when internal pressure of a fuel tank is equal to or higher than predetermined pressure, fuel evaporative gas in the fuel tank into an intake passage of the internal combustion engine while the internal combustion engine is being driven; and a prioritizing unit configured to prioritize the limiting of the output of the internal combustion engine by the limiting unit over the discharging of the fuel evaporative gas by the discharging unit, when the discharging unit is to discharge the fuel evaporative gas and the limiting unit is to limit the output of the internal combustion engine.

Control device for hybrid vehicle

A control device of a vehicle enables an engine to be operated at an operating point with a good fuel consumption efficiency, to perform power generation, without causing a sense of incongruity about noise or vibrations to a driver. With the control device, the engine is operated so that generated power of a generator increases in response to electric power required of the vehicle. Thus, the engine can be operated at an operating point with a satisfactory fuel consumption efficiency. When in an acceleration state, the engine is operated so that the increase amount of generated power is set to be larger than when in a deceleration state. When in the deceleration state, the engine is operated so that an increase in generated power is suppressed and an increase in noise is curbed.

A regenerative control device for a hybrid vehicle includes a regenerative braking power control unit prohibiting or limiting execution of first regenerative braking to charge the battery with power generated by the regenerative power generation of the traveling motor generator during deceleration when it is determined that it is necessary to restrict charging of the battery. The regenerative braking power control unit causes both second regenerative braking to transmit rotary driving power to the engine by rotating the power generation motor generator by the power generated by the regenerative power generation, and combustion operation in which fuel is supplied to the engine and the fuel is burned to generate the rotary driving power at the engine, to be executed, under condition where the execution of the first regenerative braking is prohibited or limited.
