Definitions
- the present invention relates to a power generation control device, and in particular, to a power generation control device including a generator driven by an internal combustion engine, a storage battery that stores electric power generated by the power generator, and a control device that controls the internal combustion engine and the power generator. .
- Patent Document 1 International Publication No. 2011/078189
- an EV traveling mode in which an electric motor is driven only by electric power of a storage battery (storage battery), and a series in which the electric motor is driven by electric power generated by a generator by the power of an internal combustion engine.
- a hybrid vehicle is described that is capable of traveling according to a traveling mode (see claim 1).
- the required driving force of the electric motor is derived based on the vehicle speed and the accelerator pedal opening degree, and the determination of the start of the internal combustion engine and the power generation amount of the generator are determined from the required driving force and the state of the storage battery, and the EV traveling mode or series It is disclosed that the vehicle is controlled to travel in the travel mode (see claim 1 and FIG. 4).
- Patent Document 2 Japanese Patent Application Laid-Open No. 09-2243064 has two power sources of an internal combustion engine and an electric motor, and includes an independent operation of the electric motor, an independent operation of the internal combustion engine, and a simultaneous operation of the electric motor and the internal combustion engine.
- An appropriately selected hybrid vehicle is disclosed (see claim 2). Further, it is disclosed that the internal combustion engine is operated at a constant rotational speed that indicates the best point of fuel consumption, and when the internal combustion engine is operated alone, power is generated with the surplus output of the internal combustion engine and the battery is charged. (See FIG. 3).
- Patent Document 1 International Publication No. 2011/078189 performs so-called “required output follow-up control”, determines whether to start the internal combustion engine from the required driving force and the state of the storage battery, and generates power from the generator. Determine the quantity and the rotational speed of the internal combustion engine.
- Patent Document 2 Japanese Patent Laid-Open No. 09-224364 performs so-called “fixed-point operation type control”, and the internal combustion engine is operated at a constant rotational speed indicating the best point of fuel consumption.
- the cruise output follow-up control is output control that sets the power generation amount of the generator and the rotational speed of the internal combustion engine with respect to the vehicle speed. For this reason, noise such as wind noise and road noise accompanying the increase in vehicle speed and driving sound of the internal combustion engine are interlocked with each other, and there is an advantage that the merchantability is improved. Further, even if the traveling load changes, the energy balance can be balanced.
- the power generation output commanded by cruise output tracking control does not aim at a region where the engine efficiency is good (near the fuel efficiency best point). For this reason, depending on the driving pattern, it is conceivable that power generation continues at a point deviating from the fuel efficiency best point of the internal combustion engine and the fuel efficiency decreases.
- the cruise output tracking control when the cruise speed of the vehicle is equal to or lower than the power generation start vehicle speed, for example, when a load not related to the travel load condition such as an air conditioner or a heater is operated, the storage state of the storage battery becomes a predetermined value. Power generation at the vehicle speed is not started until the following is reached. If continuous high-load operation is required when the storage state of such a storage battery is lowered, there is a concern that an energy balance may not be achieved with a low-power generator (an internal combustion engine with a small displacement).
- a low-power generator an internal combustion engine with a small displacement
- an object of the present invention is to provide a power generation control device that can improve the operation efficiency of the internal combustion engine while satisfying the required driving force of the electric motor.
- the present invention includes a generator driven by an internal combustion engine, a storage battery for storing electric power generated by the generator, the internal combustion engine, and the power generation
- a control device that controls the machine, and the control device determines whether or not the generator can generate power according to the state of the storage battery, and when power generation is permitted, is necessary for the cruise according to the running state
- the power generation amount corresponding to the output is set, and the additional power generation amount is set according to the amount of power required depending on the vehicle state and the traveling state.
- the power generation amount of the generator can be limited by the maximum power generation amount, the internal combustion engine that drives the generator is operated in a region of a predetermined efficiency or higher including the best efficiency point of the internal combustion engine. Therefore, fuel consumption can be improved.
- the present invention includes a generator driven by an internal combustion engine, a storage battery for storing electric power generated by the generator, the internal combustion engine, and A control device that controls the generator, and the control device determines whether or not the generator can generate power according to the state of the storage battery, and when power generation is permitted, the control device travels according to the running state.
- the internal combustion engine and the engine are started based on the maximum internal combustion engine rotational speed. And when the internal combustion engine rotational speed and the added internal combustion engine rotational speed are equal to or lower than the maximum internal combustion engine rotational speed, the internal combustion engine and the generator are controlled based on the internal combustion engine rotational speed and the added internal combustion engine rotational speed. It is a power generation control apparatus characterized by controlling.
- control device derives the maximum power generation amount or the maximum internal combustion engine rotation speed based on the remaining capacity of the storage battery.
- the maximum power generation amount or the maximum internal combustion engine rotation speed can be derived based on the remaining capacity of the storage battery, the maximum power generation amount or the maximum internal combustion engine rotation speed is preferably set, Even a generator or internal combustion engine with a small output can prevent overdischarge of the storage battery while satisfying the required driving force of the electric motor.
- control device derives the maximum power generation amount or the maximum internal combustion engine rotation speed based on a road surface gradient estimated value.
- the maximum power generation amount or the maximum internal combustion engine rotation speed can be derived based on the estimated slope value of the road surface, the maximum power generation amount or the maximum internal combustion engine rotation speed is preferably set. Even in the case of a generator or an internal combustion engine having a small output, overdischarge of the storage battery can be prevented while satisfying the required driving force of the electric motor.
- the power generation control device further includes a temperature adjustment unit that operates with electric power from the storage battery, and the control device derives the maximum power generation amount or the maximum internal combustion engine rotation speed according to an operating state of the temperature adjustment unit. It is preferable.
- the maximum power generation amount or the maximum internal combustion engine rotation speed can be derived based on the state of the power consuming device that is less dependent on the vehicle running state (for example, the vehicle speed).
