Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
An embodiment of the present invention provides a kind of pump oil control method, applied to electronic control unit ECU, electronic control unit
ECU is engine controller, referring to Fig. 1, show the flow diagram of pump oil control method provided in an embodiment of the present invention,
The pump oil control method can include：
Step S101：Obtain current pump oil pattern.
Wherein, current pump oil pattern is one kind in automatic pump oil pattern and manual pump oil pattern.
Automatic control mode automatically controls electrodynamic pump by ECU and carries out pump oil, and manual pump oil pattern is manual by user
It triggers electrodynamic pump and carries out pump oil, is i.e. manual trigger signal control electrodynamic pumps of the ECU based on user carries out pump oil.
Step S102：Based on current pump oil pattern, control electrodynamic pump carries out pump oil.
That is, if current pump oil pattern is automatic pump oil pattern, automatically controls electrodynamic pump and carry out pump oil, if current pump oil mould
Formula is manual pump oil pattern, then the manual trigger signal control electrodynamic pump based on user carries out pump oil.During practical application, Yong Huke
Pump oil pattern is chosen based on the actual demand of oneself.
Pump oil control method provided in an embodiment of the present invention can obtain current pump oil pattern, which is pump manually
One kind in oily pattern and automatic pump oil pattern, after current pump oil pattern is got, based on current pump oil scheme control electricity
Dynamic pump carries out pump oil.It can be seen that pump oil control method provided in an embodiment of the present invention can both automatically control electrodynamic pump progress
Pump oil, and electrodynamic pump can be triggered manually by user and carry out pump oil, i.e. provide a user multiple choices, also, manual pump oil
Pattern cause user can oneself control when start pump oil, not pump oil when this allows engine start normal, so as to avoid
Waste caused by each startup all pump oils.
Referring to Fig. 2, show another flow diagram of pump oil control method provided in an embodiment of the present invention, the pump oil
Control method is applied to electronic control unit ECU, which can include：
Step S201：Obtain current pump oil pattern.
Wherein, current pump oil pattern is one kind in automatic pump oil pattern and manual pump oil pattern.Further, pump manually
Oily pattern can include：Manual pump oil switching mode and/or manual pump oil knob pattern.
For the ease of illustrating, manual pump oil switching mode and manual pump oil knob are included with manual pump oil pattern below
It is illustrated exemplified by pattern.
Step S202a：When current pump oil pattern is automatic pump oil pattern, rail pressure is monitored in real time.
Step S203a：When the rail pressure of monitoring is less than default rail pressure, control electrodynamic pump carries out pump oil.
Wherein, default rail pressure can be the minimum rail pressure value that engine breaks down.
Step S204a：When the rail pressure of monitoring is greater than or equal to default rail pressure, control electrodynamic pump stops pump oil.
The above process is pump oil control process when current pump oil pattern is automatic pump oil pattern, below to current pump oil mould
Formula controls process to illustrate for the pump oil of manual pump oil switching mode and manual pump oil knob pattern：
Step S202b：When current pump oil pattern is manual pump oil switching mode, pump oil switching signal is detected.
Step S203b：When detecting that instruction starts the pump oil switching signal of pump oil, control electrodynamic pump carries out pump oil.
Wherein, the pump oil switching signal that instruction starts pump oil can be high level signal, i.e., ought detect high level signal
When, control electrodynamic pump carries out pump oil.
Step S204b：When detecting that instruction stops the pump oil switching signal of pump oil, control electrodynamic pump stops pump oil.
Wherein, the pump oil switching signal that instruction stops pump oil is low level, i.e. when detecting low level signal, control
Electrodynamic pump stops pump oil.
Illustratively, user thinks that oneself control electrodynamic pump carries out pump oil, when its pump operation oil circuit breaker starts pump oil, ECU
Detect high level signal, control electrodynamic pump carries out pump oil, pump oil for a period of time after, user wants to stop pump oil, at this point, user
Operable pump oil switch stops pump oil, and when user's operation pump oil, which switchs, stops pump oil, ECU detects low level, and control is electronic
Pump stops pump oil.
Manual pump oil switching mode allows user to switch control electrodynamic pump pump oil by pump oil or stop pump oil, uses
Family oneself can control when to start pump oil when stop pump oil, i.e., pump oil when user needs is unwanted in user
When not pump oil.
Current pump oil pattern is illustrated for the pump oil process of manual pump oil knob pattern below：
Step S202c：When current pump oil pattern is manual pump oil knob pattern, obtains user and set by pump oil knob
The pump oil time.
When pump oil pattern is manual pump oil knob pattern, user can set pump oil time, example by rotating pump oil knob
Such as, the pump oil time can be set as 10 minutes.
Step S203c：Control electrodynamic pump carries out pump oil based on the pump oil time that user is set by pump oil knob.
Step S204c：When the actual pump oil time reaching the pump oil time that user is set based on pump oil knob, control is electronic
Pump stops pump oil.
Some users have understanding and the demand of oneself for the pump oil time, but and manual pump oil knob pattern meets such use
The demand at family, user oneself can set the pump oil time, so that ECU is according to pump oil time control electrodynamic pump set by user
Carry out pump oil.
Pump oil control method provided in an embodiment of the present invention can obtain current pump oil pattern, which is pump manually
One kind in oily pattern, manual pump oil switching mode, manual pump oil knob pattern, after current pump oil pattern is got, base
Pump oil is carried out in current pump oil scheme control electrodynamic pump.Pump oil control method provided in an embodiment of the present invention can both automatically control
Electrodynamic pump carries out pump oil, and can trigger electrodynamic pump manually by user and carry out pump oil, i.e. multiple choices have been provided a user,
In, manual pump oil switching mode allows user oneself control when start pump oil, when stop pump oil, so as to avoid existing
Have and start waste caused by all pump oils in technology every time, and manual pump oil knob pattern allows user oneself to set pump oil
Time causes engine to be difficult to start or the pump oil time too long feelings for causing rail pressure high so as to avoid pump oil time too short-range missile
Condition.It can be seen that pump oil control method provided in an embodiment of the present invention causes, user can carry out pattern according to vehicle condition
The pump oil time may be set according to actual conditions in selection, user, and user can solve to move caused by pump oil deficiency in a short time
Hypodynamic problem can also more neatly solve engine starting problem.
