Abstract
The invention discloses a kind of diesel engine intelligence torque control methods, are related to technical field of engine control, and the first external characteristics oil mass curve is preset in the electronic control unit of diesel engine；Including：Step 101 adds the second external characteristics oil mass curve into the electronic control unit of diesel engine, and the oil mass of the second external characteristics oil mass curve is more than the oil mass of the first external characteristics oil mass curve, sets the threshold value M that turns round；Step 102 judges whether engine is hampered, and is specially：Whether monitoring engine is turned round in real time is more than the threshold value M that turns round；When engine turn round more than turn round threshold value M when, then be determined as that engine is hampered, and then the second external characteristics oil mass curve is performed in time T, then switch back into the first external characteristics oil mass curve；Otherwise, it is determined that not being hampered for engine, the first external characteristics oil mass curve is performed at this time.The increasing degree of oil mass, effectively helps engine to overcome larger resistance in the present invention control short time, keeps stabilization of speed, so as to improving production efficiency.
Description
Technical field
The present invention relates to technical field of engine control, more particularly to a kind of diesel engine intelligence torque control method.
Background technology
Available engine electronic control technology has demarcated a maximum oil mass restrictive curve engine electric-controlled unit (ECU) is inner,
Referred to as external characteristics oil mass.External characteristics oil mass limits the maximum power that engine can be sent in every speed.Engine is run
Oil mass can be increased when meeting obstructions automatically, power is improved, so as to keep the stabilization of rotating speed.But the increase of oil mass can be subject to outside
The limitation of characteristic oil mass, it is impossible to more than external characteristics oil mass.
Available engine maximum oil mass is limited by external characteristics oil mass, when engine runs into larger obstacle, due to maximum
The limitation of oil mass starts the maximum power that function is sent to be limited, is not enough to overcome resistance, so as to cause engine speed unexpected
Decline or even flame-out.
The content of the invention
The technical problem to be solved by the present invention is to：It is proposed a kind of diesel engine intelligence torque control method；When engine is run into
During larger resistance, since external characteristics oil mass limits, cause without enough torque outputs, it is impossible to resistance is overcome, so as to cause to start
Machine rotating speed bust is flame-out.
The present invention is adopted the technical scheme that solve technical problem present in known technology：
A kind of diesel engine intelligence torque control method is preset with the first external characteristics oil mass in the electronic control unit of the diesel engine
Curve；Including at least following steps：
Step 101 adds the second external characteristics oil mass curve, the second external characteristics oil mass into the electronic control unit of diesel engine
The oil mass of curve is more than the oil mass of the first external characteristics oil mass curve, sets the threshold value M that turns round；
The judgement whether step 102, engine are hampered；Specially：Whether monitoring engine is turned round in real time is more than threshold of turning round
Value M；When engine turn round more than turn round threshold value M when, then be determined as that engine is hampered, and then it is outer special to perform in time T second
Property oil mass curve, then perform the first external characteristics oil mass curve；Otherwise, it is determined that not being hampered for engine, perform at this time outside first
Characteristic oil mass curve.
Further：In the step 102, when being determined as that engine is hampered, while when throttle is more than threshold value N, engine
During in heat engine state, the electronic control unit of diesel engine performs the second external characteristics oil mass curve in time T.
Further：The threshold value N is 95%.
Further：The threshold value M that turns round is 100.
Further：It is not more than the second external characteristics oil mass Q in the oil mass of setting time internal trigger.
Further：The setting time is T=10s.
The invention has the advantages and positive effects that：
By using above-mentioned technical proposal, the electronic control unit (ECU) of the invention in diesel engine is inner to set the second external characteristics oily
Curve is measured, to control the increasing degree of oil mass in the short time, i.e., the limitation of external characteristics oil mass is decontroled in the short time；It so can be effective
Ground helps engine to overcome larger resistance, keeps stabilization of speed, so as to improving production efficiency, improves user experience；
By performing the second external characteristics oil mass curve in setting time, it can prevent the second external characteristics oil mass curve from opening
It is long, protect the service life of engine.
Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and coordinate attached drawing
Detailed description are as follows：
Referring to Fig. 1, a kind of diesel engine intelligence torque control method, first is preset in the electronic control unit of conventional diesel engine
External characteristics oil mass curve；In order to realize the goal of the invention of this patent, on the basis of above-mentioned traditional technology, this patent employ as
Under technical solution：
Above-mentioned diesel engine intelligence torque control method includes the following steps：
Step 101 adds the second external characteristics oil mass curve, the second external characteristics oil mass into the electronic control unit of diesel engine
The oil mass of curve is more than the oil mass of the first external characteristics oil mass curve, sets the threshold value M that turns round；
The judgement whether step 102, engine are hampered；Specially：Whether monitoring engine is turned round in real time is more than threshold of turning round
Value M；When engine turn round more than turn round threshold value M when, then be determined as that engine is hampered, and then it is outer special to perform in time T second
Property oil mass curve, then perform the first external characteristics oil mass；Otherwise, it is determined that not being hampered for engine, the first external characteristics is performed at this time
Oil mass curve.
By substantial amounts of experimental summary, in above preferred embodiment：The time T=10s.
In the step 102, when being determined as that engine is hampered, while when throttle is more than threshold value N, generator is in heat engine
During state, the electronic control unit of diesel engine performs the second external characteristics oil mass curve in time T.
The threshold value N is 95%.
The threshold value M that turns round is 100.
Oil mass is not more than the oil mass Q of the second external characteristics oil mass curve in setting time.
