The specific embodiment
The system architecture of Weak hybrid power automobile as shown in Figure 1.System comprises lead-acid storage battery 1, car load control unit 2, motor driver 7, the electrical generator 3 with startup function, driving engine 4, necessary switch of starter motor 5 and system and sensor 6.
Storage battery can be realized following function:
When engine starting, to 5 power supplies of traditional starter motor, so that start the engine 4;
When Parking, power to the 12V of car load electric system;
(belt-type starts ﹠amp with BSG; Electrical generator) during system start-up driving engine 4, to weak hybrid power entire car controller 2 and electrical generator 3 power supplies;
Control signal control electrical generator 3 chargings that provide by car load control unit 2 are provided when engine operation.
The maximum difference of the storage battery on storage battery of the present invention and the traditional vehicle is: during idle stop, driving engine stops operating; Satisfy idle stop at car load and start when requiring, by battery to electrical generator 3 power supplies, make system fast, steadily, low noise ground start the engine.
Under the whole service operating mode, temperature, electric current, voltage to battery are monitored in real time, and the signal conveys that sensor is arrived is to car load control unit 3, car load control unit 3 is judged the present state of battery according to detected signal, and then judges whether to satisfy the voltage request that adopts BSG system start-up driving engine 4 necessary battery electric quantities and battery according to the present state of battery.Below in conjunction with Fig. 3-5 concrete control process is described.
Car load in operational process, the voltage of the voltage request counting cell during according to electrical generator 3 generating and the difference Ve between the electric machine control voltage.Simultaneously according to the current temperature value of battery 1, the minimum voltage value V sm that tables look-up and ask maximum difference that battery allows in operation under this temperature and battery under this temperature, to allow.
When car load is in the normal course of operation, the maximum difference Vem whether the voltage difference Ve when system detects battery operation allows greater than battery.When Ve＞Vem shows that then the present capacity of battery is lower, after shutdown, can then need to charge according to default control policy operation to battery in order to guarantee car load.When Ve＜Vem, can allow system's auto-stop.
When driving engine was in stopped status simultaneously the engine ignition key is in igniting place, system detected the voltage V and the temperature T of battery.And table look-up according to the current temperature of battery and to try to achieve the required battery minimum voltage value Vsm of system's normal operation.Relation between the open circuit voltage of battery and the surplus of battery as shown in Figure 2.When the voltage V of battery＜Vsm, show that the dump energy of battery is lower, replenish electricity then battery can not satisfy the needs of integrated vehicle control tactics if can not be in time to battery, so car load control unit 2 sends request at this moment, start the engine carries out forced charge to battery.Car load control unit 2 relation between the Vem of the battery maximum that allows of the difference Ve of more current battery operation and system all the time in the forced charge process.Driving engine remains in operation to keep to battery and charges when Ve＞Vem.When Ve＜Vem, consider electrically-charged efficiency simultaneously, also need to carry out the regular hour and replenish to battery.The opening entry battery continues to mend the electrically-charged time when Ve＜Vem.When battery mend the electrically-charged time during greater than preset value the forced charge process finish.
By above-mentioned control, when guaranteeing that battery can satisfy above demand in operational process, avoided battery in operational process owing to overcharge and cross the damage that battery causes of being rivals in a contest, thereby improve the use cost that reduces battery service life of battery, improve the competitive power of hybrid vehicle.
