Abstract
A vehicle is a series hybrid vehicle that drives drive wheels using a travel motor by utilizing power of a power generation motor, which generates power by being driven by motive power of an internal combustion engine provided with a turbo charger. A method for controlling the vehicle includes executing a fuel cut of the internal combustion engine when excess power is greater than at least power that can be inputted in the system and the internal combustion engine is being supercharged.
Claims10
A control method for a series hybrid vehicle which includes a controller configured to perform control, and in which a drive wheel is driven by a travel motor using electric power of an electric power generation motor which is driven by power of an engine with a supercharger to generate the electric power, the control method comprising:
- performing a pre-detection including determining whether overflow electric power is larger than system receivable electric power;
- and
- subject to results of performing the pre-detection, performing fuel cut of the engine as the control if an excess amount of a torque over a drive engine torque of the electric power generation motor exceeds at least the drive engine torque of the electric power generation motor corresponding to the system receivable electric power indicating an electric power reception margin of a series hybrid system provided in the series hybrid vehicle, and the engine is supercharged.
A control method for a series hybrid vehicle which includes a controller configured to perform control, and in which a drive wheel is driven by a travel motor using electric power of an electric power generation motor which is driven by power of an engine with a supercharger to generate the electric power, the control method comprising:
- performing a pre-detection including determining whether overflow electric power is larger than system receivable electric power;
- and
- subject to results of performing the pre-detection, performing fuel cut of the engine as the control if magnitude of a difference between a value obtained by converting the power of the engine into the electric power of the electric power generation motor and a value obtained by converting the power of the engine capable of being received by the electric power generation motor into the electric power of the electric power generation motor exceeds at least the system receivable electric power indicating an electric power reception margin of a series hybrid system provided in the series hybrid vehicle, and the engine is supercharged.
A control device for a series hybrid vehicle in which a drive wheel is driven by a travel motor using electric power of an electric power generation motor which is driven by power of an engine with a supercharger to generate the electric power, the control device comprising:
- a pre-detection unit configured to determine whether overflow electric power is larger than system receivable electric power;
- and
- a control unit in communication with the pre-detection unit and configured to perform fuel cut of the engine if magnitude of a difference between a value obtained by converting the power of the engine into the electric power of the electric power generation motor and a value obtained by converting the power of the engine capable of being received by the electric power generation motor into the electric power of the electric power generation motor exceeds at least the system receivable electric power indicating an electric power reception margin of a series hybrid system provided in the series hybrid vehicle, and the engine is supercharged.
