Embodiment
Electric control gasoline injection engine can start obstacle when starting again after not moving for a long time, mainly be since oil pressure is not in time set up or oil-way system in bubble cause.So, the invention provides a kind of bright oil pump controller and controlling method thereof, to address this problem better.
As shown in Figure 1, be the block diagram of oil pump controller of the present invention, oil pump controller of the present invention comprises signal generating module 1, state detection module 2 and response module 3.Wherein, signal generating module 1 produces and sends the startup trigger signal of a triggering pump start.State detection module 2 detects current state and the generation of oil pump and sends the status indicator signal of the described current state of a sign.Response module 3 starts oil pump according to described startup trigger signal and status indicator SC sigmal control.
When state detection module 2 was static condition in the current state that detects oil pump, the status indicator signal of generation was for leaving standstill id signal.When state detection module 2 was operating condition in the current state that detects oil pump, the status indicator signal of generation was the running id signal.Leaving standstill id signal is two antipodal signals with the running id signal.
Certainly, response module 3 stops to produce the running control signal behind the second time period T2 that produces the running control signal, behind the 3rd time period T3 that stops to produce the running control signal if still receive sustained startup trigger signal, also can produce the running control signal, namely only start trigger signal and from invalid to effective, just produce the running control signal during saltus step receiving.
As shown in Figure 2, be the flow chart of the controlling method of oil pump controller of the present invention.The controlling method of oil pump controller of the present invention comprises the following steps:
Step S0: beginning;
Step S1: the startup trigger signal that produces and send a triggering pump start;
Step S2: detect current state and the generation of oil pump and send the status indicator signal of the described current state of a sign;
Step S3: start oil pump according to described startup trigger signal and status indicator SC sigmal control;
Step S4: finish.
In step S2, when the current state that detects oil pump was static condition, the described status indicator signal of generation was for leaving standstill id signal.
In step S3, from receiving behind the very first time section T1 that leaves standstill id signal if receive the startup trigger signal, then produce a running control signal, this running control signal is used for control and starts oil pump.If in very first time section T1, receive the startup trigger signal, then do not produce the running control signal.
In step S3, behind the second time period T2 that produces the running control signal, stop to produce the running control signal, if still receive the startup trigger signal, then produce the running control signal again behind the 3rd time period T3 that stops to produce the running control signal.If in the 3rd time period T3, receive the startup trigger signal, then do not produce the running control signal.
In addition, in step S3, behind the second time period T2 that produces the running control signal, stop to produce the running control signal, behind the 3rd time period T3 that stops to produce the running control signal if still receive sustained startup trigger signal, also can produce the running control signal, namely only start trigger signal and from invalid to effective, just produce the running control signal during saltus step receiving.
In step S1, described startup trigger signal is by driver's operation or behavior triggering for generating.As: the moment of opening car door the driver produces, or produces in the moment that the driver opens door lock, or produces in the moment of driver's vehicle seat pressurized.
As shown in Figure 3, be the first control sequential chart of the present invention, it represents non-repeated trigger pattern.At first, (state detection module 2) detects the current state of oil pump, when the current state that detects oil pump is static condition, produces and leaves standstill id signal S1; When the current state that detects oil pump is operating condition, produce the running id signal; Leaving standstill id signal S1 is two antipodal signals with the running id signal.In this sequential chart, serve as with reference to carrying out logic control to leave standstill id signal S1.Then, (response module 3) is after receive the very first time section T1 that leaves standstill id signal S1, start trigger signal S2 (signal generating module 1 produces and send this startup trigger signal) if receive, then produce a running control signal S3, this running control signal S3 is used for control and starts oil pump, so, the pump start running.But the running of oil pump only needs certain hour to get final product, and herein, the timing definition that oil pump is turned round is the second time period T2, i.e. the time length of oil pump running is the time length of the second time period T2, and oil pump stops then, returns static condition.
In very first time section T1, the second time period T2 or the 3rd time period T3, can not produce running control signal S3, and running control signal S3 only produces at the rising edge place that starts trigger signal S2, that is to say, only from invalid to effective, just produce running control signal S3 during saltus step starting trigger signal S2.If still receive and start trigger signal S2 (namely starting trigger signal S2 is in effectively) always, also must not produce running control signal S3 behind the 3rd time period T3 that stops to produce running control signal S3, namely oil pump is controlled the running that can not be triggered.That is to say: if door lock is in unlocking condition (driver has forgotten to lock a door) always, oil pump at most only is triggered operation once.
As shown in Figure 4, be the second control sequential chart of the present invention, it represents the repeated trigger pattern.At first, (state detection module 2) detects the current state of oil pump, when the current state that detects oil pump is static condition, produces and leaves standstill id signal S1.In this sequential chart, serve as with reference to carrying out logic control to leave standstill id signal S1 also.Then, (response module 3) is after receive the very first time section T1 that leaves standstill id signal S1, start trigger signal S2 if receive, then produce a running control signal S3, so, the pump start running, the time length of pump start running is the time length of the second time period T2, oil pump stops then, returns static condition.
At this moment, if producing always, (state detection module 2) start trigger signal S2, namely (response module 3) detects always and starts trigger signal S2, (response module 3) then produces running control signal S3 again behind the 3rd time period T3 that stops to produce running control signal S3, the pump start running, the time length of pump start running is the time length of the second time period T2, oil pump stops then, return static condition, if producing always, (state detection module 2) start trigger signal S2, (response module 3) then produces running control signal S3 again behind the 3rd time period T3 that stops to produce running control signal S3, so circulation is gone down.
In very first time section T1, the second time period T2 or the 3rd time period T3, can not produce running control signal S3, and running control signal S3 only produces at the rising edge place that starts trigger signal S2, that is to say, only from invalid to effective, just produce running control signal S3 during saltus step starting trigger signal S2.After stopping to produce the 3rd time period T3 of running control signal S3, start trigger signal S2 (namely start trigger signal S2 is in effectively always) if still receive, then can produce running control signal S3 again, namely oil pump can be turned round by periodic triggers.That is to say: if door lock is in unlocking condition (driver has forgotten to lock a door) always, oil pump can repeatedly be triggered operation.Under this pattern, need the long enough with the time design of the 3rd time period T3.
In Fig. 3, Fig. 4, very first time section T1 represents long time period, can start the time of obstacle for foundation is set when the setting of very first time section T1 is started after not moving for a long time again with electric control gasoline injection engine in the reality.The second time period T2 represents short time period, the setting of the second time period T2 set up with oil pressure in the reality or oil-way system in bubble time of eliminating for foundation is set.The 3rd time period T3 also represents long time period, can start the time of obstacle for foundation is set when the setting of the 3rd time period T3 is also started after not moving for a long time again with electric control gasoline injection engine in the reality.Generally speaking, very first time section T1, the second time period T2 and the 3rd time period T3 all adopt timer setting.
In addition, the 3rd time period T3 also can be set to identical time length with very first time section T1.
In a word, the change of state of the signal generating module that the present invention can cause by driver's operation or behavior and the current state of oil pump are controlled the pump start running, can guarantee that oil pressure in time sets up, bubble is fully eliminated, thereby the starting obstacle takes place when starting again after avoiding electric control gasoline injection engine not move for a long time.
The above only is embodiments of the invention, not in order to limiting the present invention, all any modifications of doing in the spirit and principles in the present invention, is equal to and replaces or improvement etc., all should be included in protection scope of the present invention.
