Abstract
The invention relates to a shifting reminding control method for a manual mode of an automatic transmission. The method comprises the following steps: under the condition that shifting activation condition is met, obtaining operating parameters of a vehicle, including a current gear value and a current engine output torque; determining an up-shift target speed and a down-shift target speed corresponding to the current gear value through the current engine output torque; prompting up-shift information if the current speed is greater than the up-shift target speed; prompting down-shift information if the current speed is lower than the down-shift target speed. Through the method, optimum fuel economy gear recommendation is performed, the purpose of helping a driver to improve the fuel economy of vehicle is achieved, and in addition, ensuring the optimum matching between speed and gear can prolong the service life of an engine.
Description
Technical field
The present invention relates to automatic gear-box control technology, be specifically related to a kind of automatic gear-box manual mode gearshift reminding method.
Background technology
At present, along with the development of auto industry is increasingly faster, domestic and business small car become increasingly popular to come into the day of people
Often between live and work.Domestic and international each automobile manufacturing company, is devoted to engine system, drive system, electromotor speed change
Case coupling and the improvement of engine electric-controlled system, in the hope of obtaining electromotor optimum Working, to reach the fuel economy of optimum.
The first scheme is to apply automatic gear-box to obtain best operating point, and first scheme is prompting driver gearshift in good time, with
Auxiliary driver identifies gearshift opportunity and target gear.
Patent of the present invention then considers under automatic gear-box manual mode, by automatic gearbox control system according to current gear information,
Engine torque information is to identify the reasonability of lifting/lowering shelves under current vehicle speed and defeated by CAN by automatic gearbox control system
Go out lifting/lowering shelves information to instrument or large-size screen monitors, to point out driver actions.
Summary of the invention
It is an object of the invention to provide a kind of automatic gear-box manual mode gearshift prompting control method, optimize car load fuel-economy
Property, it is ensured that speed is consistent with gear, reduces as far as possible and gear and the nonsynchronous situation of speed occurs due to human pilot carelessness, tool
Body technique scheme is as follows:
A kind of gearshift prompting control method, for the manual mode of automatic gear-box, in the case of satisfied gearshift activation condition,
Employing following steps:
(1) obtain the operational factor of vehicle, determine upshift target vehicle speed corresponding to current shift value and downshift target vehicle speed；
(2) if described current vehicle speed is more than described upshift target vehicle speed, then prompting upshift information；
(3) if described current vehicle speed is less than described downshift target vehicle speed, then prompting downshift information.
Further, step is exported moment of torsion by present engine in (1), determines the upshift target carriage that current shift value is corresponding
Speed and downshift target vehicle speed.
Further, operational factor described in step (1) includes that current shift value, present engine export moment of torsion.
Further, step (1) obtains the operational factor of vehicle by being arranged at the sensing device of car load.
Further, the upshift target vehicle speed that in step (1), gear value is corresponding and downshift target vehicle speed default in full-vehicle control
In device.
Further, prompting described in step (2) and (3) uses buzzing, and/or vibrations, and/or the mode of flash of light is entered
OK.
Compared with currently available technology, the present invention by automatic gear-box control unit output lifting/lowering shelves signal to CAN, then
Being received by instrument and show, real-time reminding driver rises downshift, makes speed and gear coupling, it is possible to be beneficial to energy-saving and emission-reduction and carry
High engine life
Accompanying drawing explanation
Fig. 1 implements the control principle drawing intending reminding with the gearshift provided for the present invention；
Detailed description of the invention
Describing the present invention below according to accompanying drawing, it is a kind of preferred embodiment in numerous embodiments of the present invention.
In a preferred embodiment, in the case of satisfied gearshift activation condition: obtain the operational factor of vehicle, described work as
Front engine output moment of torsion, determines upshift target vehicle speed corresponding to described current shift value and downshift target vehicle speed；Work as if described
Front speed is more than described upshift target vehicle speed, then prompting upshift information；If described current vehicle speed is less than described downshift target vehicle speed,
Then prompting downshift information.
In a further advantageous embodiment, following scheme can be used: a kind of automatic gear-box manual mode gearshift reminding method,
The method includes: in the case of satisfied gearshift activation condition: obtain the operational factor of vehicle, wherein, described operational factor bag
Include current shift value, present engine output moment of torsion；Exported moment of torsion by described present engine, determine described current shift value pair
The upshift target vehicle speed answered and downshift target vehicle speed；If described current vehicle speed is more than described upshift target vehicle speed, then point out upshift
Information；If described current vehicle speed is less than described downshift target vehicle speed, then prompting downshift information.By the method, carry out optimal
Fuel economy gear is recommended, and helps driver to reach to improve the fuel economy purpose of vehicle, it is additionally ensured that speed and gear
It is in optimal coupling, the service life of electromotor can be improved.
By the method, carry out optimal fuel economy gear recommendation, help driver to reach to improve the fuel economy mesh of vehicle
, furthermore it is ensured that speed is consistent with gear, reduces as far as possible, due to human pilot carelessness, gear and the nonsynchronous feelings of speed occur
Condition.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements and is not subject to the restrictions described above,
As long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved directly apply to other occasion
, all within protection scope of the present invention.
