Accumulator 16 is in parallel with starter 17 constitutes starting electricity consumption loop；Described DC converter (DC/DC) 9, car load electrical equipment 8,
Full-vehicle control unit (HCU) 7, the positive source of control unit of engine (ECU) 18 are parallel to electric power loop A point, described normally closed
Side, relay 14 contact connects starting battery positive pole, and contact other side is connected to electric power loop A point；Described fuse
13 one end are connected with electric power loop A point, and other end is connected with side, normally opened relay 12 contact, and described normally opened relay 12 touches
Point other side connects voltage stabilizing battery positive voltage.Car load high-tension battery power conversion is 12V low-tension supply by described DC/DC
Power for car load.Described ECU18 controls starter work.Described HCU can be with described EBS1, described EBS2 and described
It is mutual that ECU carries out information, and described HCU is by the normally opened relay 12 described in control and described normally closed relay 14, it is achieved rise
Engine start controls.Described pair of battery power supply system also apply be applicable to conventional truck, only need to change to described DC/DC 9 pass
The electromotor of system car.Under car load after electricity, normally closed relay 14 is in closure state, and normally opened relay 12 is in disconnection shape
State, starting battery 16 is individually for car load and provides power supply, and voltage stabilizing accumulator 11 disconnects with car load power electrical apparatus.
See Fig. 3, described hybrid power starter start engine control strategy comprise car load power on control strategy, stop
Car starter starts engine control strategy, driving starter starts engine control strategy, fault coping strategy.Described stops
Car starter starting electromotor controls to comprise single accumulator starter starting electromotor control and the starting of double accumulator starter is sent out
Motivation controls two submodules.Described fault reply control comprises the reply of message class fault and controls and starter Fault Control two
Individual submodule.
Seeing Fig. 4, the described car load control strategy that powers on comprises the steps of first described HCU by described
EBS1 obtains starting battery state-of-charge, arranges the charged lower limit of starting battery 30%, if starting battery SOC
Less than 30%, then forbidding that vehicle travels, otherwise control strategy walks judgement under entering；Secondly, described HCU is by described EBS2
Obtain voltage stabilizing storage battery charge state, the charged lower limit of voltage stabilizing accumulator 30% is set, if voltage stabilizing accumulator SOC is less than
30%, then normally opened relay 12 forbids Guan Bi, and DC/DC work enable, for entire automobile electric system offer power supply, forbids vehicle driving
The middle starting duty of engine；Otherwise HCU control normally opened relay 12 closes, and HCU judges normally opened relay closing of contact shape simultaneously
State, it is judged that method is as follows: EBS2 detects voltage stabilizing battery current, and current status message is sent HCU, HCU by inspection by EBS2
In surveying 0.1s, whether current value is more than 0.2A, if more than 0.2A, then normally opened relay 12 contact is in closure state, otherwise, often
Open relay 12 contact is off.DC/DC works enable, provides power supply for entire automobile electric system, and the flow process that powers on terminates.
Seeing Fig. 5, described parking starter starts engine control strategy and comprises the steps of first, and HCU judges car load
Whether meeting starter working condition, comprise three Rule of judgment a) front clutch and depart from, b) ECU can to HCU transmission electromotor
Using starter to start engine condition message, c) engine speed is zero, if three above condition can not meet simultaneously, and, no
Can adopt cranking engine with starter, otherwise control strategy enters next step judgement.Secondly HCU judges normally opened relay 12 contact
State, if normally opened relay 12 is off, then enters parking ticket accumulator starter and starts electromotor control flow.Institute
State HCU and adopt cranking engine with starter message, starter fault detect and the reply control of starter fault to described ECU transmission
See that fault reply controls, complete flow process after parking starter starts electromotor and terminate.If normally opened relay 12 is in closure state,
Then enter double accumulator starter that stops and start electromotor control flow.Described HCU controls described normally closed relay 14 and disconnects, institute
State HCU and adopt cranking engine with starter message, starter fault detect and the reply control of starter fault to described ECU transmission
Seeing that fault reply controls, after engine ignition, described ECU sends engine ignition success message to described HCU, and described HCU prolongs
Time 0.5s after close described normally closed relay 8.
Seeing Fig. 7, described driving starter starts engine control strategy and comprises the steps of: the most described HCU judges
Following condition, a) front clutch departs from, and b) ECU sends electromotor to HCU and can use starter starting engine condition message, c)
Engine speed is zero, and d) starting battery temperature is in the range of 0 DEG C to 60 DEG C, and e) starting battery SOC is more than 70%,
F) starting battery SOF_V1 is more than 7.5V, and g) normally opened relay 12 gets an electric shock and is in closure state, if above seven conditions are not
Can meet then HCU uses power motor to drag engine ignition control strategy simultaneously.If above seven conditions can meet, then simultaneously
Described HCU sends to described ECU and adopts cranking engine with starter message, starter fault detect and the reply control of starter fault
System is shown in that fault reply controls.After engine ignition, described ECU sends engine ignition success message, described HCU to described HCU
Described normally closed relay 14 is closed after time delay 0.5s.
Described fault reply control comprises the reply of message class fault and controls and two submodules of starter Fault Control.Institute
The message class fault reply control stated refers to that system message is abnormal, and described EBS1 or EBS2 state reports an error.When system produces system
During message exception, forbid that in driving, starter starts electromotor control function and double accumulator parking starter starts electromotor control
Function processed.Described starter Fault Control sees Fig. 6.HCU sends to ECU and uses starter to start engine ignition message
After, ECU can control starter and drag electromotor, and ECU sends engine speed message to HCU, in the time T of regulation, if HCU
The rotating speed message received is zero, then judge engine failure, forbids using starter to start the duty of engine, simultaneously HCU control
Normally closed relay 14 processed closes, and vehicle uses power motor to start engine mode.
