The energy control method of hybrid vehicle of the invention, in conjunction with vehicle-state, round trip operation characteristic and
Battery capacity may be implemented the optimum control of the hybrid vehicle energy, fuel economy can be improved.
Detailed description of the invention
This specification includes the following drawings, and shown content is respectively:
Fig. 1 is the operation schematic diagram of the energy control method of hybrid vehicle of the present invention；
Fig. 2 is battery operated mode schematic diagram.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation, it is therefore an objective to those skilled in the art be helped to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and facilitate its implementation.
The present invention provides a kind of energy control methods of hybrid vehicle, comprise the following steps that
The remaining capacity of S1, the operation information for obtaining hybrid vehicle and battery；
S2, according to the operation information of hybrid vehicle and the remaining capacity of battery, determine the target of hybrid vehicle
Operating mode；
S3, control hybrid vehicle enter target operational mode.
Specifically, the operation information of hybrid vehicle includes in energy-output ratio and traveling in above-mentioned steps S1
Journey, hybrid controller calculates the energy-output ratio and mileage travelled of hybrid vehicle in real time, and carries out to rechargeable energy
Estimation.The operation information of hybrid vehicle further includes the operation characteristic of the round trip of hybrid vehicle, the operation information
It further include the first starting point, the second starting point, First terminal point and the second terminal of hybrid vehicle, in hybrid vehicle
In round trip, the first starting point is identical as the second terminal, and the second starting point is identical as First terminal point, the first starting point and first
Terminal is respectively starting point and the destination of first stroke, and the second starting point and the second terminal are respectively the starting point of second stroke
The destination and.
In above-mentioned steps S2, target operational mode includes pure electric vehicle drive mode, when battery works in electric quantity consumption mould
When formula, hybrid vehicle enters pure electric vehicle drive mode.In above-mentioned steps S3, hybrid vehicle enters pure electric vehicle driving
After mode, sailed by motor output power driving hybrid electric vehicle, engine stop work.
In above-mentioned steps S2.Target operational mode further includes driving charging series model, is protected when battery works in electricity
When holding mode, hybrid vehicle enters driving charging series model.In above-mentioned steps S3, hybrid vehicle enters driving
It charges after series model, is generated electricity by engine driving motor, motor charges the battery, and is driven by engine output power
Driven mixed power running car.
In above-mentioned steps S3, after hybrid vehicle enters driving charging series model, engine as needed
Energy, the working time of estimating engine, and determine the opportunity of engine stop driving motor.
As shown in Figure 1, Trip1 (first stroke) and Trip2 (second stroke) constitutes one section of round trip, in first stroke
In, start to estimate when the electric quantity consumption half of battery, in the case where the electricity of battery is sufficient, energy budget is not appoint
What is necessary, at this moment battery working power consumption patterns, and with the increase of vehicle driving mileage, the electricity stored by battery continues
It reduces.When first stroke terminates, i.e., running car to First terminal point, this First terminal point are also setting out for second stroke
Point, while the opportunity that engine needs to intervene is estimated, and the energy provided remains unchanged, with the increase of mileage, battery enters
Charge-sustaining mode, at this time engine start charges, when rechargeable energy reaches the value that engine power estimates module output, hair
Motivation stops working.
The present invention is exemplarily described in conjunction with attached drawing above.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out；Or not
It is improved, above-mentioned conception and technical scheme of the invention are directly applied into other occasions, in protection scope of the present invention
Within.
