Current oil pump control is mainly to pass through FP Fuel Pump Relay.When after car engine, engine controller sends control signal control oil pump relay closes, and engine oil is given in Oil pump electrical machinery full-speed operation, ensures the normal working of motor.Unnecessary fuel oil is got back to fuel tank by return line, forms the loop of fuel oil.
But also there are some defects for the controlling method of oil pump in current engine controller.Be mainly manifested in the following aspects:
1, Economy.At present engine controller is only control oil pump relay closes when the car engine for the control of oil pump, and Oil pump electrical machinery starts to keep full-speed operation afterwards.This is a kind of controlling method of open loop, and control accuracy is lower.Especially in the time of idling or the slow-speed of revolution, because fuel delivery requirement is lower, Oil pump electrical machinery continues to keep running up, and the oil mass pumping is much larger than the demand of motor, and most fuel oil need to flow back to fuel tank by return line.On fuel economy, this controlling method is not best undoubtedly.
2, travelling comfort.Due to the defect in controlling method, Oil pump electrical machinery can keep full speed running always, and especially, in the time of idling or the slow-speed of revolution, the noise of Oil pump electrical machinery can bring negative effect to driving comfortability.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of engine oil pump control system in order to overcome the defect that above-mentioned prior art exists, by pulse duration modulation (PWM) control oil pump motor, and complete speed feedback with position-sensor-free, realized the accurate closed loop control to oil pump.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of engine oil pump control system, be connected with the final controlling element of control oil pump, this control system comprises kernel control module, driver module, state monitoring module and feedback module, described kernel control module connects respectively driver module, state monitoring module and feedback module, and described final controlling element connects respectively driver module, state monitoring module and feedback module.
Described kernel control module is microprocessor.
In described kernel control module, be embedded with pulse width modulating signal circuit for generating.
Described driver module is made up of bridge circuit.
Described feedback module comprises without position speed probe.
Compared with prior art, the utlity model has following advantage:
One, improved fuel economy: native system is by pulse duration modulation (PWM) control oil pump motor, and complete speed feedback with position-sensor-free, realize the accurate closed loop control to oil pump, can effectively improve fuel economy, reduced automobile fuel consumption.
Two, improved driving comfortability: in idling and slow-revving situation, because the demand for oil mass is low, native system microprocessor can, according to the rotating speed of the different regulating working conditions oil pumps of motor, reduce the noise of Oil pump electrical machinery, thereby improves driving comfortability.
Three, improved drive safety: the safety of oil circuit is very important in automotive system.Native system forms state monitoring module by sensors such as voltages, electric current, temperature, and the running state of Oil pump electrical machinery is carried out to Real-Time Monitoring, can prevent from, due to the contingency causing that is short-circuited of the interface of engine controller, guaranteeing oil circuit safety.
