Description
Technical field
The invention belongs to car electrics fields, and in particular to the control method of vehicle intelligent power management system.
Background technique
Car electrics configuration at present is more and more abundant, and appliance power is increasing.Such as: 7 seat coach thirds emptying adjusting system,
Room lamp system (atmosphere lamp, ceiling light, gate light, glove box lamp, makeup lamp), PTC heating system, sound equipment power amplifier etc..It is existing
Have vehicle vehicle under unstart engine conditions in the case where the debugging of entire factory, user 4S shop test run by battery
It is powered.Electrical appliance function is more and more abundant, and debug time is increasingly longer, power consumption is increasing necessarily causes battery to go out
Existing electric deficiency phenomenon.Not only it had influenced battery service life itself but also terminal user is caused to bring embracing for starting difficulty due to discharged or defective battery
Resentment, however in view of lead-acid accumulator weight and cost cause accumulator capacity again it is not possible that the actual conditions that ad infinitum increase.
It so then needs to be managed battery based on the above fact, reduces the accumulator electric-quantity under unstart engine conditions and disappear
Consumption.Guarantee vehicle can start next time and prolonging service life of battery.
Summary of the invention
Goal of the invention: it is an object of the present invention to provide a kind of control methods of vehicle intelligent power management system, for whole
Under vehicle unstart engine conditions, differentiated control is carried out to vehicle power load, is finally reached and reduces accumulator electric-quantity consumption, prolong
The purpose of the long life of storage battery.
Technical scheme is as follows:
A kind of control method of vehicle intelligent power management system: storage battery sensor carries out the state of lead-acid accumulator
Monitoring, leads to the charged state SOC of the battery detected, functional status SOF, health status SOH, voltage U, current I signal
It crosses LIN bus and is sent to power source management controller, signal operation processing is generated power management grade by power source management controller to be believed
Number PMS_ level and battery capacity low signal LowPowerWarning, is sent to load controller by CAN network；It is each negative
Set controller makes corresponding load management and in real time according to the power management level signal and battery capacity low signal received
Electric quantity of power supply situation feedback.
PMS_ level signal is defined as 0x0,0x1,0x2 altogether in power source management controller, tetra- grades of 0x3:
1 SOC of 0x0:Level=> 80% & SOC_State==(1or2)
The 0x1:Level & of 2 70%≤SOC < 80% SOC_State==(1or2)
The 0x2:Level & of 3 60%≤SOC < 70% SOC_State==(1or2)
The 0x3:Level & of 4 SOC < 60% EMS_SOC_State==(1or2).
LowPowerWarning signal is defined as 0x0,0x1,0x2 in power source management controller, tetra- grades of 0x3:
0x0 accumulator electric-quantity is normal;SOC=> 80% & SOC_State==(1or2)
0x1 accumulator electric-quantity is low;The & of 60% < SOC < 80% SOC_State==(1or2)
0x2 accumulator electric-quantity is extremely low;The & of 50% < SOC≤60% SOC_State==(1or2)
0x3 charging instruction;SOC < 50%&SOC_State==(1or2).
The load management be by load controller by low speed CAN network receive PMS_ level with
Two signals of LowPowerWarning load driving circuit based on the received and carry out big minor adjustment to the end voltage of load, thus
Reach the function of grade of load adjusting.
The control method of vehicle intelligent power management system, which is brought, is advantageous in that accumulator status, which can be monitored in real time, to be reminded
User's accumulator electric-quantity situation, user is good is accustomed to vehicle for guidance.Also after sale thousand frequency of battery can be effectively reduced, reduce master
Machine factory after cost, the life ensuring vehicle for finally extending battery being capable of normal starting.
Detailed description of the invention
Fig. 1 is control method block diagram of the present invention；
Fig. 2 is each controller line connection block diagram of the present invention.
Specific embodiment
1 the invention will be further described with reference to the accompanying drawing
Step 1: calibration storage battery sensor and accumulator parameter, specific scaling method is by static and two kinds of dynamic
Battery demarcate test method determine lead-acid battery VCO curve, 25 DEG C when internal resistance, to calculate SOC, SOC_
The signals such as State, SOF, SOF_ State.And signal is integrated in the RAM of sensor.And storage battery sensor has LIN
Bus transmission-receiving function.In the whole process, battery is also required to carry out largely matching examination with the starting capability of engine
It tests, under cryogenic conditions, the corresponding engine start ability of accumulator capacity, accumulator capacity corresponds to engine under hot conditions
Starting capability, correspond to engine start ability using the storage battery after 1 year.
Step 2: power source management controller handles the storage battery sensor signal that LIN bus receives, power supply pipe
Reason controller CPU is low with battery capacity signal operation processing generation power management level signal (PMS_level) received
(LowPowerWarning) two signals.Wherein PMS_ level shares 4 state grades, and LowPowerWarning shares 4
A state grade.Below to PMS_ level, two signals of LowPowerWarning are described in detail；
PMS_ level signal is defined as 0x0,0x1,0x2, tetra- grades of 0x3 altogether in power source management controller.
1 SOC of 0x0:Level=> 80% & SOC_State==(1or2)
The 0x1:Level & of 2 70%≤SOC < 80% SOC_State==(1or2)
The 0x2:Level & of 3 60%≤SOC < 70% SOC_State==(1or2)
The 0x3:Level & of 4 SOC < 60% EMS_SOC_State==(1or2)
LowPowerWarning signal is defined as 0x0,0x1,0x2, tetra- grades of 0x3 in power source management controller.
0x0 accumulator electric-quantity is normal;SOC=> 80% & SOC_State==(1or2)
0x1 accumulator electric-quantity is low;The & of 60% < SOC < 80% SOC_State==(1or2)
0x2 accumulator electric-quantity is extremely low;The & of 50% < SOC≤60% SOC_State==(1or2)
0x3 charging instruction;SOC < 50%&SOC_State==(1or2)
Step 3: each load controller receives PMS_ level and LowPowerWarning two by low speed CAN network
Signal makes relevant load management and the warning of real-time battery capacity.Basic load controller has AC air-conditioner controller, BCM vehicle body
Controller, LCM lamp dimmer, SEAT seat controller, DVD host.The last above controller receives power management control
Control response is made after the level signal of device and electric quantity of power supply low signal is shown in control panel, to observe and to control in real time
Each actuator working condition.
Citing illustrates:
1 AC air-conditioner controller of example
PMS_ level==0x0 is received, then controller blower air quantity is adjustable to maximum；
PMS_ level==0x1 is received, then controlling blower air quantity allows to adjust to maximum 75%；
PMS_ level==0x2 is received, then controlling blower air quantity allows to adjust to maximum 50%；
PMS_ level==0x3 is received, then does not allow to open air blower.
2 DVD host controller of example
LowPowerWarning==0x0 is received, then display interface is without prompt；
LowPowerWarning==0x1 is received, is prompted " battery capacity is low, and partial function will be limited "；
LowPowerWarning==0x2 is received, is prompted " battery capacity is extremely low, please start engine use "
LowPowerWarning==0x3 is received, is prompted " accumulator electric-quantity will exhaust, and please charge "
2 pairs of function logic realizations of the present invention are further elaborated with reference to the accompanying drawing
Step 1: then storage battery sensor acquisition circuit acquisition battery voltage, electric current, temperature pass through sensor CPU
