Description
Technical field
The present invention relates to hybrid vehicle starting method, particularly relate to a kind of starting method for hybrid power car.
Background technology
In orthodox car, power is provided by driving engine, therefore start the engine is only had could to provide power to car load, its automobile engine starting is primarily of mechanical ignition lock control, 0FF, ACC, IG, START tetra-gears set up respectively by ignition lock, when connecting IG shelves, the working power of all electrical equipment is all switched on, and being in can mode of operation; When connecting START shelves, starting relay is switched on, and starter motor work drags engine ignition and makes engine starting; After engine starting, ignition lock key springs back to IG shelves, and engine starting process terminates.
In current oil electric mixed dynamic new-energy automobile, power is divided into two parts, a part is still traditional driving engine as power, another part be motor/generator as power, the electrical source of power of electrical motor is provided (being generally 288V direct current (DC)) by high tension battery.Compare with conventional car, car load can be operated in pure motoring condition or engine-driven state, also jointly can be driven by driving engine and motor/generator; And the engine starting of hybrid vehicle is driven by motor/generator, eliminate the starter motor of conventional car, therefore the startup of hybrid electric vehicle engine and conventional car different, simultaneously in order to realize manage the intelligent charge of low tension battery, anti-theft system and anxious stopping control and participation control for brake, the power management section of general hybrid power system is entered mechanical key without key and is started (PEPS) module (containing POWER switch) by special and manage, and relies on mechanical ignition lock control to be irrealizable merely.About the correlation function of PEPS and effect can be on 07 07th, 2010 in publication date, publication number is know in the patent documentation of CN 101769093A.
Power-supply management system start the engine (electrical motor) roughly process by PEPS module composition: first unblanked by remote-control key remote control or machinery, make PEPS module work, if now first time presses POWER switch, key enters ACC state by power supply after certification, second time is by entering ON state afterwards, and starting the self-inspection of ON state, third time, by then entering OFF state, makes car load power-off.In officely once step on brake pedal by POWER switch simultaneously, then enter READY(ready) state, and carry out READY self-inspection, as self-inspection is normal, enter start-up course, entire car controller (HCU) controls the control unit relevant with power such as electric machine controller (PEU), battery management system (BMS), engine controller (EMS), according to flow startup driving engine or the electrical motor of setting, makes car load be in wheeled state.
But PEPS module making cost and maintenance cost higher, be suitable in the vehicle than higher-end, inapplicable in low and middle-end vehicle.
Summary of the invention
Main purpose of the present invention is to provide a kind of hybrid power car starting method, and it cancels POWER switch and PEPS module realizes hybrid power car startup, has the features such as cost is low, the simple dependable performance of control setup.
The present invention is directed to that prior art problem mainly solved by following technical proposals, a kind of hybrid power car starting method, comprises the steps:
1) entire car controller connects battery management system, engine controller, electric machine controller and instrument by communication bus; One mechanical ignition lock is set, the ACC shelves of mechanical ignition lock connect ancillary apparatus parts in car, IG shelves connect necessary electric component when driving a vehicle, START shelves connect one end of an igniting relay coil, the other end of this coil is by entire car controller output port ground connection, open contact one end ground connection other end of described ignition relay connects the input port of entire car controller, cuts off the power supply of all electrical equipment on car when mechanical ignition is locked in OFF shelves;
2) mechanical ignition lock pushes IG shelves, and the output port of entire car controller is by one end ground connection of ignition relay coil;
3) mechanical ignition lock pushes START shelves, ignition relay coil energization, open contact closes, after entire car controller obtains ground connection incoming signal, detect brake pedal signal, if receive brake pedal actuating signal, vehicle control unit controls battery management system, engine controller, electric machine controller enter ready state, battery management system controls high voltage direct current and enters electric machine controller, and carry out ready state self-inspection, if do not receive brake pedal actuating signal, do not enter ready state;
4) during ready state self-inspection, decontrol ignition lock key, make key spring back to IG shelves, ignition relay discharges; If ready state self-inspection success, enters start-up course, vehicle control unit controls electric machine controller, battery management system, engine controller, according to flow startup driving engine or the electrical motor of setting, make car load be in wheeled state, start-up course terminates;
5) if ready state fail self-test, then by described instrument display fault type, cut off high direct current (DC), exits start-up course simultaneously.
This hybrid power car start up system mainly comprises the correlation module such as mechanical ignition lock, entire car controller (HCU), battery management system (BMS), engine controller (EMS), electric machine controller (PEU), instrument.On vehicle circuitry, ACC shelves circuit connects audio/video player, Cigarette lighter waits for bus interior ancillary apparatus parts; IG shelves circuit connects when driving a vehicle necessary as modules such as HUC, BMS, EMS, instrument, EPS, cuts off the power supply of all electrical equipment when OFF shelves.
When mechanical ignition is locked in IG shelves, HCU is by one end ground connection of ignition lock relay coil, during START shelves, the conducting of ignition relay power supply, open contact closes, HCU obtains ground signalling, the signal of the similar POWER switch of this ground signalling, such HCU can receive actuation signal, if also receive brake pedal actuating signal simultaneously, the module such as HCU and BMS, EMS, PEU enters ready self-inspection and Ready self-inspection state, and BMS controls high voltage direct current and enters PEU, if do not receive brake pedal actuating signal, then do not enter Ready state; If Ready self-inspection success, enters start-up course, HCU control PEU, BMS, EMS, according to flow startup driving engine or the electrical motor of setting, car load is made to be in wheeled state; If Ready self test failure or IMMO authentication error, HCU cuts off igniting relay power ground, and car load cannot start again; play a protective role; cut off high direct current (DC) simultaneously, by instrument or audio/video player read-out display fault type, exits start-up course.
As preferably, mechanical ignition is locked in ACC shelves, IG shelves or ready state fail self-test and springs back to IG shelves, when ignition lock key rotates to OFF shelves, and supply disconnecton, all electrical equipment cuts out; If readiness self-inspection success key springs back to IG shelves, when ignition lock key rotates to OFF shelves, all current consumer power supplys are all closed, wherein automatically close after the time delay of associated high voltage DC power module, namely except the galvanic module of associated high voltage work on power supply after certain hour automatically close except (completed by the time delay circuit of correlation module, be mainly used in the release of forceful electric power energy), all current consumer power supplys are all closed.
As preferably, arrange ready self-inspection indicator lamp in instrument, green indicating lamp flicker during ready state self-inspection, after self-inspection success, green indicating lamp is long bright, and fail self-test yellow indicator lamp is bright.
The beneficial effect that the present invention brings is, utilizes traditional mechanical ignition lock to form hybrid power car start up system, eliminates POWER switch and PEPS module, have the features such as cost is low, control setup simple, dependable performance; And whether the work of ignition relay is by HCU module controls, when occurring Ready fault or be in anti-theft state, HCU cuts off igniting relay power loop, makes vehicle cannot again enter Ready state.
