Description
Technical field
The present invention relates to electrical vehicular power device more particularly to a kind of motor of the pure electric vehicle logistic car based on driving habit
Torque method of adjustment.
Background technique
Electric drive is an important component in new-energy automobile technology, and due to its clean and environmental protection, drive efficiency is high,
The simply equal many advantages of structure are possessing preferable market-oriented prospect at this stage.Power source of the engine as orthodox car, to the greatest extent
Pipe relative maturity is stablized, but there is also noise is big, structure is complicated, the problems such as feature of environmental protection difference.With battery motor in recent years
Etc. the development of technologies and the support of national policy, more and more vehicle factors released hybrid electric vehicle and pure electric vehicle vehicle,
In the long run, motor will have the great potential for gradually substituting engine.The driving habit of different drivers has differences, if
It can make motor output according to driving habit rationally, then can take into account pure electric vehicle logistic car dynamic property and economy.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of Motor torque adjustment side of the pure electric vehicle logistic car based on driving habit
Method.
The purpose of the present invention can be realized by following technical proposals: a kind of pure electric vehicle logistic car is based on driving habit
Motor torque method of adjustment, includes the following steps:
S1, it obtains drive parameter and is transferred to entire car controller；
S2, entire car controller are analyzed and are handled drive parameter by algorithm；
S3, matching driving habit model；
S4, according to matched driving habit model, vehicle control unit controls motor increases slope to adjust demand torque and torque.
Further, in S1, the drive parameter includes speed, gear, average speed, acceleration, accelerator open degree and frequency
Rate, brake aperture and frequency, average accelerator open degree, aperture of averagely braking, shift frequency, parking frequency.
Further, in S2, the algorithm includes fuzzy algorithmic approach, neural network algorithm.
Further, in S3, the driving habit model include fierce driving habit model, common driving habit model,
Gentle driving habit model.
Further, in S4, if fierce driving habit model, then increase demand torque and torque increases slope to adjust
Motor；
If common driving habit model, then slope is increased using average demand torque and torque to adjust motor；
If gentle driving habit model, then motor is adjusted using reducing demand torque and slowing down torque growth slope.
Compared with prior art, beneficial effects of the present invention: the whole-control system of pure electric automobile passes through drive parameter
Carry out integrated treatment judge current driver's driving habit how, the thus demand torque and torque of pure electric automobile motor
Increase slope and make adaptive matching, thus different demands of the allowing for driver to dynamic property and economy.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
Below in conjunction with the attached drawing specific embodiment that the present invention will be described in detail, those skilled in the art is made to become apparent from geography
How solution practices the present invention.Although describing the present invention in conjunction with its preferred embodiment, these embodiments are
It illustrates, is not intended to limit the scope of the invention.
Referring to Fig. 1, a kind of Motor torque method of adjustment of the pure electric vehicle logistic car based on driving habit includes the following steps:
S1, obtain drive parameter and be transferred to entire car controller, the drive parameter include speed, gear, average speed, acceleration,
Accelerator open degree and frequency, brake aperture and frequency, average accelerator open degree, aperture of averagely braking, shift frequency, parking frequency, this
The acquisition of a little drive parameters can be realized by sensor；
S2, entire car controller are analyzed and are handled drive parameter by algorithm, and the algorithm includes fuzzy algorithmic approach, neural network calculation
Method；
S3, matching driving habit model, the driving habit model include fierce driving habit model, common driving habit mould
Type, gentle driving habit model；
S4, according to matched driving habit model, vehicle control unit controls motor increases slope to adjust demand torque and torque.
If fierce driving habit model, then need to properly increase vehicle dynamic property, at this time entire car controller needs to count
It calculates bigger motor demand torque and bigger torque increases slope, so that vehicle has better dynamic property and faster
Dynamic response.
If common driving habit model, then need to improve the economy of vehicle at this time, at this time entire car controller needs
It calculates relatively small Motor torque and relatively small torque increases slope, so that vehicle accelerates gentler, dynamic property
Opposite to weaken, economy gets a promotion.
If gentle driving habit model, then demand of the entire car controller to dynamic property and economy makes balance, torque
It calculates and torque growth slope should drive between fierceness and gentle driving is intermediate.
It should be pointed out that can also have the embodiment of a variety of transformation and remodeling for the present invention through absolutely proving,
It is not limited to the specific embodiment of above embodiment.Above-described embodiment as just explanation of the invention, rather than to this
The limitation of invention.In short, protection scope of the present invention should include that those are apparent to those skilled in the art
Transformation or substitution and remodeling, and be determined by the appended claims.
