As shown in figure 4, the major control function logic of cold start controller is as follows：
Cold start main processes define：
Cold start controller 6 IGN power VBAT after, when press cold starting switch, then will proceed by second into
Gas the pre-heat treatment, super capacitor processing, the processing procedure of prompting permission engine start (buzzer call).
Cold start aid in treatment process defines：Cold start controller 6 is powered in IGN after VBAT, is risen not pressing low temperature cold
Before dynamic switch, then the processing procedure of the first charge heating processing will be proceeded by.
Wherein, IGN power supplies VBAT is the precondition that the power supply of cold start controller is started to work.
Cold start controller 6 starts power up initialization and self-test after IGN powers VBAT：Cold start controller 6 is supplied in IGN
Carry out Initialize installation after electric VBAT to each function module, including the initialization of I/O port, Bus Clock Rate initialize, are fixed
When the initialization of device, the initialization of A/D module, the initialization of CAN module, the initialization of watchdog module, while to controller sheet
Body carries out self-test, checks that each circuit whether there is failure.
After the completion of above power-up initializing and self-test, switch into controller working status, wherein, controller working status
Switch, input collection and fault detect processing, the processing of the first charge heating, the second charge heating is handled, super capacitor is handled, carried
Show the processing of permission engine start (buzzer call), be in continuous circular treatment.Unless re-powering or CPU is answered
Position signal triggering, will restart Booting sequence.
Controller working status includes normal operating conditions and standby operating status.
Work normally shape under, automated execution power-up initializing and self-test after the power is turned on, if initialization and self-test complete and
Do not detect failure, working state signal (including OUT4.6 super capacitor working statuses, OUT4.7 liquid are updated in CAN bus
Body heater working status, OUT4.8 cold start controllers working status) it is both configured to normally be sent to Multi-function display control
Device, while cold start controller enters normal operating conditions.In normal operation according to control logic to related cold start
Ancillary equipment such as super capacitor controller, charge heating heater strip and buzzer load etc. are controlled processing.
Under standby operating status, when the process flow of cold start controller 6 is completed or (including any in process flow process
The processing of the first charge heating of process flow, the processing of the second charge heating, super capacitor processing, prompts to allow engine start (bee
Ring device pipes)) in detection IN5. engine speed CAN message collection input judge that engine has been turned on, then can enter standby work
Make state.In this case, controller is substantially carried out AD detections, CAN communication, and without the main processing procedure of cold start
(including the second charge heating processing, super capacitor processing, prompts to allow engine start (buzzer call)).
After the working status switching of controller is completed, it will go into input collection and fault detect handled.
Input collection and fault detect processing：The signal mainly gathered includes the switch input of IN1 cold startings (after collection
Signal OUT4.1 cold starting on off states are sent by CAN bus and input to multifunction display and engine controller
EMS), the input of IN2 temperature collections (sends signal OUT4.2 environment temperatures (analog quantity) to issue after collection by CAN bus
Multifunction display displays temperature value), the detection input of IN3 liquid (boiler) heater failure (is sent after collection by CAN bus

After input signal collection and fault detect, when the state for detecting the switch input of IN1 cold startings does not have
Open and then enter cold start aid in treatment process (including the processing of the first charge heating)；When detect IN1 cold startings switch
The state of input is to open, then enters (including the second charge heating processing, at super capacitor of cold start main processes
Reason, prompts to allow engine start (buzzer call)).
The processing of first charge heating：(detect that IN1 cold startings switch is defeated before cold starting switch is not pressed
The state entered is not turned on), according to the environment temperature (input of IN2 temperature collections) and engine coolant temperature detected
(IN6 coolant temperatures CAN message collection input), after certain algorithm judges, cold start controller is sent out by CAN bus
The number of delivering letters OUT4.5 charge heatings admissions control gives engine controller (EMS), and EMS feeds back CAN bus letter after being disposed
The input of number IN7EMS charge heatings state of a control carries out the interaction of signal, the first charge heating relay 9 and the second charge heating
Relay 10 drives the first charge heating heater strip 7 to carry out aid in treatment to the charge heating of engine.
The processing of second charge heating：(the switch input of IN1 cold startings is detected after cold starting switch is pressed
State is opened), according to the environment temperature (input of IN2 temperature collections) and engine coolant temperature detected, (IN6 is cooled down
Liquid temperature degree CAN message collection input), after certain algorithm judges, cold start controller sends signal by CAN bus
OUT4.5 charge heatings admissions control gives engine controller (EMS), and EMS feeds back CAN bus signal after being disposed
The input of IN7EMS charge heatings state of a control carries out the interaction of signal, while is inputted and believed according to IN7EMS charge heatings state of a control
When number judging that EMS is not handled charge heating, cold start controller is by driving the control output pair of OUT2. charge heatings
The charge heating of engine is mainly handled, i.e. the first charge heating relay 9 and the second charge heating relay 10 drive
Second charge heating heater strip 8 works to strengthen the cold starting performance of engine.
Super capacitor processing：Cold start controller is powered in IGN after VBAT, (detection after cold starting switch is pressed
State to the switch input of IN1 cold startings is opened), cold start controller will drive the control output control of OUT1. super capacitors
Super capacitor charging processed is enabled, and detects charging full state IN4. super capacitors full of indication signal detection input.This
Processing procedure carries out parallel with the processing of the second charge heating, and time is started so as to reduce.
Prompting allows engine start (buzzer call)：Cold start controller is powered in IGN after VBAT, when pressing low temperature
(detect that the state of IN1 cold startings switch input is opened) after cold start switch and super capacitor handles and the second air inlet
In the case that the pre-heat treatment is all completed, the driving OUT3. buzzer control outputs of cold start controller make exterior buzzer sounding ring
Cry, to prompt user's engine to allow to start, can start to twist ignition lock starting engine, at this time pass through CAN bus
Send OUT4.9 preheatings to complete, engine can be started to multifunction display, prompted over the display by the form of word
User；If find that engine does not have also by detecting the collection input of IN5. engine speed CAN message after a certain time
There is startup, then sending OUT4.10 preheatings by CAN bus completes, and engine is not actuated to give multifunction display, terminates afterwards cold
Start preheating treatment procedure；If hair is found by detecting the collection input of IN5. engine speed CAN message within a certain period of time
Motivation has been started up, then exits cold start preheating treatment procedure, normally complete the pre-heat treatment.
