Electronic control unit is TCU.TCU (Transmission Control Unit) i.e. automatic gear-box control unit,
It is usually used in the automatic transmission such as AMT, AT, DCT, CVT.It realizes automatic shift control, makes to drive simpler.TCU be by 16 or
The composition such as 32 bit processors, signal processing circuit, power driver module, will pass through stringent electromagnetic compatibility testing.Its work
Temperature depend on installation site, be typically mounted in cockpit, it is desirable that temperature grade it is lower, -40 DEG C to 90 DEG C；If peace
Mounted in enging cabin, temperature grade is usually -40 DEG C to 140 DEG C；Pass through the vehicle mounted electrics such as CAN bus and ECU, ABS/ESP, BCU
Brain communication, engine torque is controlled when automatic gear-box breaks down, and limits gear, realizes limp-home function.TCU terminal
The information such as the location information of GPS, travel speed, vehicle can be passed back to system platform by wireless transmission method by equipment, be used
Family can realize the monitoring and management to vehicle by computer, mobile phone.
Specifically, temperature sensor is provided in automatic gear-box, temperature sensor is for incuding in automatic gear-box
Oil temperature, and the oil temperature data that will test is sent to electronic control unit.It is realized using temperature sensor in automatic gear-box
Oil temperature real-time detection, temperature sensor belongs to the prior art, is not explained in detail here.
Automatic gear-box further includes having gear box, electronic control unit and being set in the gear box
Hydraulic control valve body, the hydraulic control valve body is for controlling each oil circuit switching and oil pressure shift component in the automatic gear-box
Movement is to realize speed change；The hydraulic control valve body includes multiple solenoid valves, and the solenoid valve comes from the electricity for receiving
The oil pressure shift component is adjusted in the control signal of sub-control unit, the solenoid valve at least one be normal high electromagnetism
Valve.Gearshift magnetic valve used by existing hydraulic automatic gearbox (AT) is all normal-low magnetic valve, the characteristic of normal-low magnetic valve
Curve is as shown in Fig. 2, pressure increases with the increase of electromagnetic valve current, i.e., when electric current reaches maximum value 1500mA, pressure reaches
To 20bar, solenoid valve is completely closed；And the characteristic curve of normal high magnetic valve as shown in figure 3, pressure with electromagnetic valve current increasing
Big and reduces, i.e., when electric current is 0, pressure can arrive 20bar, and solenoid valve is completely closed, pass through the operating mode of solenoid valve
Change, can reduce the output of electric current, to reduce oil consumption.
Specifically, hydraulic control valve body includes to wear cylinder connector, wears cylinder connector connection solenoid valve and electronic control is single
Member wears cylinder connector and receives the control signal from electronic control unit, and controls the opening and closing of solenoid valve.By wearing cylinder connector
Control of the electric signal to solenoid valve of electronic control unit is realized, so that the transmission of electric signal is more stable.
The quantity of solenoid valve be 5, respectively B1 brake solenoid valve, C1 clutch solenoid valve, C2 clutch solenoid valve,
C3 clutch solenoid valve and C4 clutch solenoid valve, wherein at least one solenoid valve are normal high magnetic valve, and other solenoid valves are
Normal-low magnetic valve.Existing 8AT has used 5 normal-low magnetic valves to control as clutch pressure, by carrying out to existing 8AT
The test of one NEDC circulation, calculates every grade of power consumption, the sum of electric current of each solenoid valve of duration * of every grade of power consumption=every grade * 12,
Such as total power consumption=all gears of P grades of power consumption=32* (1.5+1.5) * 12=1152,8AT are whenever the sum of power consumption.
Existing 8AT shift logic power consumption is as shown in table 1, according to existing 8AT shift logic table：P, R, N, D1,
This five gears of D2 use always, and there are three solenoid valves to power for each gear, shown in following chart 1：
Table 1
It, can will be by B1 brake solenoid valve and C4 clutch solenoid valve the two solenoid valves more by the analysis to table 1
It is changed to normal high magnetic valve, the power consumption after change is as shown in table 2, it can be seen that P, R, N, D1, D2 this five gears, be up to one
Solenoid valve power supply, blocks in P/N and does not power, for supporting that the TCU output power consumption of shift is 0, as shown in table 2：
Table 2
By the comparison to Tables 1 and 2 it is recognised that by the two electricity of B1 brake solenoid valve and C4 clutch solenoid valve
After magnet valve is changed to normal high magnetic valve, the lower power consumption of entire automatic gear-box system 23.9%, i.e. 23.9%=
(63108-48024)/63108.Therefore, automatic gear-box provided by the invention is compared with existing automatic gear-box, power consumption
It is lower therefore more energy saving, its use cost is reduced, more economical material benefit.
In conclusion increasing automatic gear-box the present invention provides a kind of method of automatic gear-box low temperature self study and existing
The quick self-adapted function of low temperature, and this primary function, the touching of this function are only triggered in automatic gear-box whole life cycle
There are two conditions for hair, one is the oil temperature in automatic gear-box is lower than 60 DEG C, the second is automatic gear-box did not carried out also normally
60 DEG C of -105 DEG C of oil temperature sections self-adapting program so that vehicle is after cold-starting for the first time, automatic gear-box at this time
In electronic control unit the triggering of low temperature self-learning function, when complete 5 low temperature self-learning functions can this program of compulsory withdrawal,
So that the gear shifting quality of vehicle is good, automatic gear-box all no longer needs to carry out adaptively；Automatic learning data is stored simultaneously
Into the storage unit of automatic gear-box, client carries out that storage can be transferred automatically when low temperature is shifted gears for the first time after vehicle enters market afterwards
