Description
Technical field
The present invention relates to a kind of car gear shifting variation pattern and device; Refer in particular to a kind of inclination angle identification control method and device based on automobile-used AMT speed change gear; Be applicable to all kinds of urban public traffic vehicles of assembling AMT automatic shifting transmission; Realize the judgement of the driving gradient, in time change the gear shift control strategy, improve the power performance and the reliability of climbing.
Background technique
The AMT technology of automobile belongs to the mode that a kind of novel automobile conversion keeps off, and so-called AMT technology is to realize self shifter through electronic control machinery speed change.It is on the basis of traditional mechanical transmission and dry clutch; Gear shift mechanism to clutch operating mechanism and speed changer carries out the motorized transformation; Applying electronic control technique and various kinds of sensors; By gearbox controller (TCU) motor, motor working state (like power and rotating speed), the speed of a motor vehicle, throttle, braking and condition of road surface etc. are analyzed, handled, and engine controller (ECU), electric machine controller and operating device are sent instruction, coordinate the action of clutch, gearshift, motor; In reasonable time, accomplish corresponding action, realize full-automatic shift speed change with suitable speed.AMT has kept the basic system of original mechanical gearbox, compares with AT (fluid torque converter) commonly used, and the AMT automatic transmission case has following advantage:
1. cost is low, and only being increases self-clanging gear-shift to get final product on the basis of manual transmission;
2. cost of use is low, in the using process with manual transmission identical maintenance method and upkeep cost;
3. maintenance, easy to maintenance, the AT automatic transmission case of present bus at home is less, and owing to the less maintenance of accessory, maintenance ten minutes trouble, and the AMT automatic transmission case is identical with manual transmission aspect keeping in repair, safeguarding, the accessory abundance;
4. transmission efficiency is high, because the transmission efficiency of the principle of gearbox difference AMT automatic transmission case is higher than the AT automatic transmission case far away, thereby makes vehicle oil consumption low than AT.
But, with regard to present AMT gearbox, because it constitutes and to increase on the basis all be based on the conventional manual gearbox that automatic executing agency realizes.So; The shortcoming of not carrying out AMT gearbox contrast AT gearbox under the situation of depth optimization at the gearbox body is also fairly obvious: AMT is for cutting off power shfit; Shifting shock is bigger, and AMT will be inferior to AT on switching speed simultaneously, has influenced driving comfortability to a certain extent.Especially for urban public traffic vehicles, because the travel of urban public traffic vehicles is good, the ramp is little, for improving AMT smooth gear shifting performance, acceleration performance and fuel-economizing performance, when vehicle start, often adopts the control strategy of AMT being hung 2 retaining startings.The enterprising row of road stops when starting but vehicle is on the abrupt slope, if still adopt the strategy words of 2 retaining startings, might cause the starting inefficacy, and vehicle falls to slip, and potential safety hazard occurs.Therefore how accurately carrying out the gradient and judge, in time change the gearshift strategy, is to improve the power performance of climbing and the effective measures of reliability.
Summary of the invention
The objective of the invention is to judge inaccurate deficiency for all kinds of urban public traffic vehicles gradients that solve existing assembling AMT automatic shifting transmission; A kind of new inclination angle identification control method and device based on automobile-used AMT speed change gear are proposed; Realize the accurate judgement of the driving gradient; In time change the gear shift control strategy, improve the power performance and the reliability of climbing.
Technology implementation scheme proposed by the invention is following:
A kind of inclination angle identification control method based on automobile-used AMT speed change gear; Mounted angle sensor on the fixed component of lower vehicle; Dip sensor is electrically connected with the gearbox controller of vehicle, and issues gearbox controller to the vehicle gradient data that detected incessantly; When vehicle is parked in the ramp and prepares to carry out start-up function; Dip sensor can detect the gradient in its ramp rapidly; And these gradient data are issued gearbox controller (that is: TCU), and TCU will judge this gradient, the gear shift mechanism through speed changer places suitable gear with speed changer.If upgrade is bigger, speed changer will place 1 gear (bottom gear); Otherwise,, level road little or descending like upgrade, speed changer will place 2 gears or high speed gear, thus starting performance is stopped on the slope that guarantees vehicle.
Preferably, described dip sensor is installed on the vehicle frame between the two-wheeled of vehicle, can conveniently discern the angle of inclination of vehicle through the fluctuating of two-wheeled.
Preferably, the choosing shelves of the gear shift mechanism of speed changer control principle is when the gradient of level road or climb and fall is spent greater than 10, to select 2 grades; When the gradient of climb and fall is spent less than 10, select 1 grade.
According to a kind of inclination angle recognition device that said method proposed based on automobile-used AMT speed change gear; Comprise car body, gearbox controller and AMT speed changer; It is characterized in that mounted angle sensor on fixed component at lower vehicle; Dip sensor is electrically connected with gearbox controller, and the value of slope on dip sensor collection vehicle and ground, and the data that will mould collection are passed to gearbox controller through electrical signal; Carry out gear by gearbox controller according to determined rule and select, and speed changer is placed suitable gear through the gear shift mechanism of speed changer:
Preferably, described dip sensor is installed on the vehicle frame between the two-wheeled of vehicle, can conveniently discern the angle of inclination of vehicle through the fluctuating of two-wheeled.
If the gradient is bigger, speed changer will place 1 gear; Otherwise speed changer will place 2 gears.Thereby starting performance is stopped on the slope that guarantees vehicle.
Advantage of the present invention mainly is:
● can detect the gradient in vehicle driving ramp.
● place suitable gear through making speed changer, be responsible for vehicle start.
