Description
Technical field
The invention belongs to motor vehicle driven by mixed power field, particularly relate to a kind of hybrid power control method of finished based on GPS.
Background technology
New-energy automobile industry is one of emerging strategic industries of giving priority to of China, along with the propelling of China's energy-saving and emission-reduction policy, the quantity of integral new-energy passenger will get more and more, particularly plug-in hybrid-power automobile, because its Technical comparing is ripe, manufacturing cost is lower, and effects of energy saving and emission reduction is obvious, is the best product realizing the energy-saving and emission-reduction of traffic aspect present stage.
The plug-in hybrid passenger car used at present, in energy management control policy, certain in usual selection SOC value is a bit as equilibrium point, and with this for benchmark determines the upper and lower bound of SOC, region between upper and lower bound is exactly the conventional work area of battery SOC, and the charge value in battery usually will fluctuation in this is interval.After battery is full of electricity by external source, first entire car controller can be considered to consume part electric energy, and battery electric quantity is entered in predetermined SOC operation interval.Because control system does not know road conditions, can not intelligent decision be made, the management of electric energy can only be controlled by a pattern, therefore must occur the problem that electric energy service efficiency is low, the regenerative brake percent recovery is low.
Summary of the invention
Because the above-mentioned defect of prior art, technical matters to be solved by this invention is to provide a kind of hybrid power control method of finished that can improve vehicle electric energy service efficiency, reasonable employment electrokinetic cell volume space, the raising regenerative brake percent recovery.
For achieving the above object, the invention provides a kind of hybrid power control method of finished based on GPS,
Gather and the road of circulation line is composed, gather link length, road grade, the length in every section of ramp, the starting point in every section of ramp and final position in the spectrum of this road simultaneously;
Gps system is utilized to realize the location constantly of vehicle, when vehicle runs at the circuit set, entire car controller is composed according to the road of circulation line, the position at vehicle place and the service direction of vehicle, controls the open and close of vehicle motor, motor, and the work area of driving engine.
Preferably, before vehicle drives to upward slope starting point, system is by according to the length in ramp reserve power to greatest extent, release electrical energy drive motor balanced in the process of vehicle driving up is to vehicle booster, driving engine is made to work in efficient district all the time, realize drive efficiency maximum, reach the effect of energy-saving and emission-reduction.
Before vehicle drives to descending starting point, the length according to ramp is used electric energy by system to greatest extent, makes battery reserve enough storage areas.When vehicle descending, system carries out Brake energy recovery by motor, and the part kinetic energy of vehicle is converted to electrical power storage in battery, and simultaneity factor also will kill engine and further improve energy-saving effect.
When vehicle drives to the starting point of flat road, the pure motor under the state that kills engine according to the realization of the length of flat road and the electricity limit of battery storage drives and travels by system, saving fuel to greatest extent.Utilizing electric power generation to regulate when needing engine drive the load started, making engine operation in efficient district, realizing energy-saving and emission-reduction.
Adopt above technical scheme, utilize gps system in conjunction with condition of road surface, reasonably utilize the energy content of battery, realize the target that automotive power combined efficiency is the highest, realize the control overflow that automobile energy-saving rate is the highest.The present invention can according to the difference of road conditions, selects corresponding energy distribution strategy thus realizes the real-time adjustment of control policy, can better adapt to line condition, reduce complete-vehicle oil consumption further, promote fuel economy.Above technical scheme can greatly improve vehicle electric energy service efficiency low, improve the power cell of vehicle regenerative brake percent recovery.
The invention has the beneficial effects as follows: the present invention has held the mainstream development direction of Technology of Hybrid Electric Vehicle, and integrated level is high, highly versatile, good energy-conserving effect.The present invention utilizes gps system in conjunction with condition of road surface, reasonably utilize the energy content of battery, greatly improve vehicle electric energy service efficiency low, improve the power cell of vehicle regenerative brake percent recovery, achieve the target that automotive power combined efficiency is the highest, realize the control overflow that automobile energy-saving rate is the highest.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
