Described automobile pretrigger inductor 101, before running at motor, send pre-actuation signal to described controller 102, described pre-actuation signal is the pre-actuation signal that described automobile pretrigger inductor 101 sends when being triggered.
Described automobile pretrigger inductor 101 is the device of the automobile the responded to pretrigger except motor, such as, and Ke Yiwei: car door trigger switch or seat belt sensor or opening door of remote-control signal receiver or the pressure transducer under being positioned at operator cabin seat.When automobile pretrigger inductor 101 is car door trigger switch, user is after by car door opening, and car door trigger switch is sent to controller 102 by pre-actuation signal after sensing and opening; When automobile pretrigger inductor 101 is seat belt sensor, after user fastens automobile safety belt, seat belt sensor is sent to controller 102 by pre-actuation signal; When automobile pretrigger inductor 101 is opening door of remote-control signal receiver, user utilize remote-control key for automobile unlock time, opening door of remote-control signal receiver is sent to controller 102 by car door pre-actuation signal; When automobile is positioned at the pressure transducer under operator cabin seat, driver is sitting on the seat in operator cabin, and pressure transducer is sent to controller 102 by pre-actuation signal.Because car owner is before the motor starting automobile, certainly to open car door in advance or fasten one's safety belt or utilize remote-control key unlock for automobile or be sitting on the seat in operator cabin, so car door trigger switch, seat belt sensor, opening door of remote-control signal receiver and pressure transducer all can as automobile pretrigger inductors 101.Natch, automobile pretrigger inductor 101 can be not only door trigger switch, seat belt sensor, opening door of remote-control signal receiver and pressure transducer, as long as first can send automobile pre-actuation signal for controller 102 before the engine start of automobile.
Described controller 102, for receiving pre-actuation signal that described automobile pretrigger inductor 101 sends and controlling described electronic oil pump 103 operate after receiving described pre-actuation signal.
Controller 102 can for ECU (ElectronicControlUnit) controller that automobile is installed, and ECU controller, also known as " car running computer ", " vehicle-mounted computer " etc.Then automobile specified computer controller from purposes, it is the same with common computer, is made up of microprocessor (CPU), storage (ROM, RAM), input/output interface (I/O), analog-digital converter (A/D) and the large-scale integrated circuit (LSI) such as shaping, driving.ECU controller collects each several part work state information of motor by various inductor (comprising car door trigger switch, seat belt sensor, opening door of remote-control signal receiver, temperature transducer, pressure transducer, turn-sensitive device, flow transducer, position transducer etc.), is sent to ECU by the circuit of responsible transmission.After ECU have received these signals, will analyze various signal, just can learn which type of state each component function of motor is in, function situation how information, then according to the automatic computing of program finished writing in advance, which executive component should be allowed in this condition to do which thing, then instruction is sent to executive component, order executive component works.Natch, user also can install the controller that can realize above-mentioned functions voluntarily.
Consider when automobile pretrigger inductor 101 is for car door trigger switch, the object of the car door opened as car owner is only used to have a rest into car, instead of in order to steering vehicle trip.When car door trigger switch is sent to controller 102 through automobile pre-actuation signal, it can be constantly still engine oil that controller 102 controls electronic oil pump 103, causes the waste of oil mass.Therefore, described system can also comprise the first speed probe 104 of the rotating speed for measuring described motor, and described first speed probe 104 is electrically connected with described controller 102, and described controller 102 is preset and is equipped with the significant interval time.
Described controller 102, also for judge to control the running of described electronic oil pump 103 after receiving described pre-actuation signal the described significant interval time in whether receive the tach signal that described first speed probe 104 sends, if not, then control described electronic oil pump 103 to shut down.
In general, car owner from opening car door, band fastens one's safety belt, then opens to igniting the time that motor needs 30 seconds (certain, this time can be arranged as the case may be voluntarily), therefore the described significant interval time can be set to 30 seconds.When controller 102 received the automobile pre-actuation signal of car door trigger switch transmission after 30 seconds, still the tach signal that the first speed probe 104 sends is not received, namely think that car owner opens car door and is only used to enter rest in automobile, then control electronic oil pump 103 fuel cut-off, avoid the waste of oil mass, energy-conserving and environment-protective.
Consider that the mechanical oil pump of prior art is the running by driven by engine mechanical oil pump, when the rotation of motor is very fast, (such as, automobile on a highway fast running time), mechanical oil pump is also along with the faster rotational speed (such as, the rotating speed of motor is 4000r/min, and the rotating speed of mechanical oil pump is also 4000r/min) of motor, therefore, the oil mass that mechanical oil pump provides for motor also increases accordingly.In fact, when engine speed is 4000r/min, only need the rotating speed of oil pump for about 2500r/min for motor provides oil mass just, the too high waste that not only can cause lubricant oil of oil mass, and the oil pressure of the cylinder of motor car engine can be caused too high, oil pressure is too high may damage head gasket.
Therefore, described system can also comprise the second speed probe 105 for measuring electronic oil pump 103 rotating speed, and controller 102 is pre-stored with the rotating speed ratio of the rotating speed of electronic oil pump 103 rotating speed and motor, and described rotating speed ratio is for being less than 1, better with 0.6.
Described controller 102, also for receiving the tach signal of the tach signal of described motor that described first speed probe 104 sends and the described electronic oil pump 103 that the second sensor sends respectively.
Motor car engine utilizes the speed probe of crank position to realize to the rotating speed exporting detecting motor usually.Such as: the rotational speed of motor can be transformed into electrical signal and be sent to controller 102 by speed probe.
Controller 102 is according to the described rotating speed ratio of prestor, the tach signal of described motor received and the tach signal of electronic oil pump 103, regulate the rotating speed of electronic oil pump 103, equal the described rotating speed ratio of prestor with the rotating speed ratio of the rotating speed of the rotating speed and motor that make electronic oil pump 103.
