Now will be in detail with reference to the preferred embodiments of the present invention, its example is illustrated in the drawings, and is described below.Although the present invention will be described in conjunction with the embodiments, it should be understood that this description is not to be limited to present embodiment to the present invention.On the contrary, the present invention not only will cover present embodiment, and to cover may be included in by various in the defined the spirit and scope of the present invention of appended claims substitute, revise, equivalence and other embodiments.
As shown in figs. 1 and 2, the present invention includes the following step: whether the ready state of heating (hereinafter being called " no-load operation heating ") is ready when being identified for idling of vehicle; Determine whether vehicle stops; Determine whether the outer temperature of car has reached winter temperature; Operation no-load operation heating pattern.
For this purpose, the present invention includes the no-load operation heating switch, the velocity transducer that is used to detect car speed that are used for no-load operation heating, be used to measure the external temperature sensor 400 of the outer temperature of car and the cooling-water temperature sensor 500 that is used to measure cooling water temperature.In addition, the present invention also comprises electric control unit (ECU) 100, and being used for changes heating mode when the data that receive from these sensors satisfy pre-conditioned luck line space.
More specifically, in the whether ready step of the ready state that is identified for no-load operation heating, after key operation is opened, checked whether the no-load operation heating switch that is used for no-load operation heating is opened.
At this moment, if key operation open, and if the no-load operation heating switch also open, then the ECU100 electric condition that is identified for no-load operation heating satisfies, and the preparation that is used for no-load operation heating is also finished.
In determining the step whether vehicle stops, check that speed changer remains on neutral state, check accelerator (pedal) by the accelerator switch operation, and increasing and be in the scope of 2km/h-5km/h or be equal to or less than 2km/h by velocity transducer 300 speed that checks vehicles.
When satisfying these conditions, that is: the prespecified range of the inoperative of the neutral state of speed changer, accelerator and car speed, ECU 100 determines that vehicles stop.
Whether temperature has reached in the step of winter temperature outside determining car, use external temperature sensor 400 to determine whether external temperatures are equal to or less than 5 ℃ or increasing and be in 5 ℃-8 ℃ the scope, use cooling-water temperature sensor 500 to determine whether cooling water temperatures are equal to or less than 60 ℃ or increasing and be in 60 ℃-70 ℃ the scope.When one of condition of external temperature and cooling water temperature satisfied, ECU 100 determined that the outer temperature of cars has reached winter temperature.
When the condition of all these steps all satisfies, ECU 100 operation no-load operation heating patterns.In the step of operation no-load operation heating pattern, the rpm of motor (rpm) quantity is increased to 900rpm, and mandatory operation exhaust brake.
This of motor increases rpm and improved the heater working force relevant with engine-driving power.The operation of exhaust brake makes closure close by the operation of exhaust actuator, thereby can increase and spray into fuel quantity by increasing the engine load amount, so that the heat that sends from motor can be increased to the scope of about 7%-10%.
Now, will be discussed in more detail below the control logic circuit of Fig. 2.
With reference to figure 2, when the key operation that is used for power supply is in IGNITION ON state, and when the no-load operation heating switch was in the ON state, logic value 1 sent the first logic AND arithmetic mean unit 110 to again.When key operation was in the START state, logic value 1 sent the first logic AND arithmetic mean unit 110 to.When speed changer was in the NEUTRAL state, logic value 1 sent the first logic AND arithmetic mean unit 110 to.
At this moment, when the no-load operation heating switch is not in the ON state, and speed changer is not when being in the NEUTRAL state, and logic value 1 neither sends the first logic AND arithmetic mean unit 110 to, does not also send the second logic AND arithmetic mean unit 120 to.Thereby, remove the no-load operation heating pattern.
Subsequently, when the accelerator off-duty, logic value 1 sends the second logic AND arithmetic mean unit 120 to.When increasing by velocity transducer 300 measured vehicle speed and being in the scope of 2km/h-5km/h or when being equal to or less than 2km/h, logic value 1 sends the second logic AND arithmetic mean unit 120 to.
At this moment, when the accelerator off-duty, and when car speed is reducing and is in the scope of 5km/h-2km/h or when being equal to or less than 5km/h, logic value 1 neither sends the second logic AND arithmetic mean unit 120 to, does not also send the 3rd logic AND arithmetic mean unit 140 to.Thereby, remove the no-load operation heating pattern.
Subsequently, be equal to or less than 60 ℃ or increasing and when being in 60 ℃-70 ℃ the scope, logic value 0 sends logic NAND arithmetic mean unit 130 to when the cooling water temperature of measuring by cooling-water temperature sensor 500.When the external temperature of being measured by external temperature sensor 400 is equal to or less than 5 ℃ or increasing and when being in 5 ℃-8 ℃ the scope, logic value 0 sends logic NAND arithmetic mean unit 130 to.
At this moment, when cooling water temperature is equal to or greater than 70 ℃ or reducing and when being in 70 ℃-60 ℃ the scope, and when external temperature is equal to or greater than 8 ℃ or reducing and when being in 8 ℃-5 ℃ the scope, be 0 by the logic value of the 3rd logic AND arithmetic mean unit 140 outputs.Thereby, remove the no-load operation heating pattern.
In other words, when via the first logic AND arithmetic mean unit 110, the second logic AND arithmetic mean unit 120 and logic NAND arithmetic mean unit 130, when equaling logic value 1 by the value of the 3rd logic AND arithmetic mean unit 140 output, ECU 100 is increased to 900rpm with the rpm of motor, and mandatory operation exhaust brake, thereby under the situation of not using independent preheater, can improve heating properties.
Although described embodiments of the invention for purpose of illustration, it will be appreciated by those skilled in the art that, various modifications, increase and to substitute all be possible, and do not break away from as disclosed scope and spirit of the present invention in the appended claims.
