Abstract
A vehicle 10 includes an accessory system 40 coupled to an engine control module 26. The accessory system 40 may, for example, be a snow plow. The accessory system 40 is coupled to a first pin 30 and a second pin 32 of the engine control module. When both of the pins are high, the idle speed of an engine 12 is raised so that the speed of the alternator 14 is raised so that a battery 16 may maintain a charging level on the battery.
Description
Technical field
Present invention relates in general to a kind of control system, more specifically, relate to and a kind ofly can discern snowplow or other annexes and improve the idling of motor so that allow the engine control system of battery charge.
Background technique
Usually various annexes can be connected to heavy-duty car as snowplow.Under the situation of snowplow, use is operated snowplow from the hydraulic system that automobile obtains power.Normally under the low-down speed of a motor vehicle, use snowplow.The low speed of a motor vehicle is corresponding to low engine speed.If the rotating speed of motor is low excessively, then can not be to battery charge.In the operation period of snowplow, in operate the plough sword under the slow-speed of revolution on all places, this may cause that battery discharges fully usually.
Therefore need the operation of identification annex and increase engine speed so that battery is maintained charged state.
Summary of the invention
The invention provides a kind of automotive system, this automotive system comprises engine control module and is connected to first pin of engine control module and the annex of second pin.The idling that engine control module increases motor is the situation of high petential to respond first pin and second pin.
In another aspect of this invention, a kind of method of operating automobile comprises when first pin of determining the engine control module connector is connected by the annex high petential with second pin, and the increase idling is the situation of high petential to respond first pin and second pin.
An advantage of the invention is that this system can operate when automobile is in driving model.That is, can in adjustable limit, increase motor per minute rotating speed RPM and not require the Parking pattern.
When checking according to the detailed description of preferred embodiment with claims in conjunction with the accompanying drawings, other advantages of the present invention and feature will become apparent.
Description of drawings
Fig. 1 is the block diagram that has according to the automobile of control system of the present invention.
Fig. 2 illustrates the flow chart that is used to operate method of the present invention.
Embodiment
With respect to snow plough attachment following accompanying drawing is described.Yet, one skilled in the art will understand that various other annexes that also can be applied to automobile operation period use.
Refer now to Fig. 1, automobile 10 comprises the motor 12 that is connected to alternator 14 as shown.Alternator 14 is connected to battery 16.Though illustrated battery 16 is two different frames, on an automobile, provide a battery usually.When motor 12 rotations, alternator 14 rotates and generating.When alternator was higher than certain rotating speed, alternator served as generator and produces the electric power that is used for battery 16 chargings.Motor 12 is connected to speed changer 20, and speed changer 20 has the output corresponding to vehicle condition.For example, speed changer 20 can produce the output corresponding to driving or drive pattern.This is to be different with such other patterns of for example reversing mode and Parking pattern.
Engine control module (ECM) 26 is connected to motor 12 and controls motors 12 according to the various parameters of automobile.For example, engine control module 26 can be controlled engine idle.Engine control module 26 comprises engine control module connector 28, and engine control module connector 28 can have for example cell charge protection pin 30 and power output connecting pin 32.Certainly, various other pins also can be used for being coupled and input or output the information of engine control module 26.Engine control module 26 can also be connected to fan 33 and Parking Brake 36.Engine control module 26 can be controlled the rotating speed of fan 33, and can receive the information of the activation or the disconnection of relevant Parking Brake 36.
Cell charge protection (BCHP) pin 30 and power output (PTO) pin 32 are called first pin and second pin.Accessory system 40 can be connected to first pin 30 and second pin 32 by connector 42. Pin 30 and 32 boths can be connected to operation loop (run feed) 44 and snowplow switch 46.When annex as snowplow 58 of needs operations, closed and two pins of snowplow switch 46 or cell charge protection pin 30 and PTO pin 32 all are connected to and move loop 44.When automotive ignition is opened, with 44 energisings of 16 pairs of operation loops of battery.When automotive ignition was closed, operation loop 44 just no longer activated.
Annex 40 can have the module as snowplow module 48.The snowplow module can be connected to snowplow switch 46.When needs activated snowplow, snowplow module 48 can be connected to battery 16 by switch 50.When first pin 30 and second pin 32 received the high petential indication, engine control module increased the idling of motor.For example, idling can be increased to about 200RPM, so that can carry out battery charge.The amount that increases depends on a lot of conditions, comprises the type or the output of engine type, alternator, reaches the amount of the required power of annex.In addition, the rotating speed that can change fan 33 when annex is provided comes cooled engine.In one example, when both are high petential at first pin 30 and second pin 32, rotation speed of the fan can be increased so that allow further cooled engine.Also can respond Parking Brake 36 and increase engine cooling.When the signal that Parking Brake 36 generation indication Parking Brakes are closed, engine control module can increase the rotating speed of fan 33.This can be in conjunction with the supervision of pin 30 and 32 is carried out.
It should be noted that high petential refers to energising or cell voltage pattern in this case.It should be noted that the high petential condition can be any condition except that grounding requirement or disconnection condition.That is, high petential cell voltage or reverse cell voltage both, or the voltage that is lower than cell voltage may be used to indicate the high petential condition.
Refer now to Fig. 2, a kind of method of the present invention that is used to operate is shown.In step 100, check pin state and the basic idling and the speed of a motor vehicle.Can be by all these three conditions in engine control module 26 inspections or the periodic polling step 100.In step 102, be not in high petential or the speed of a motor vehicle greater than zero or idling during at two pins being paid close attention to greater than basic idling, system returns step 100 and reexamines entry condition.In step 102, if pin is a high petential and the speed of a motor vehicle equals zero and idling equals basic idling, then this shows that the annex as snowplow is connected to automobile, and has enabled the snowplow pattern.In step 104, all these three conditions all are met, and improve engine idle with predetermined amount.As mentioned above, predetermined amount can be about 200RPM.This amount can change according to motor.Importantly keeping engine idle is in and can allows alternator to battery charge or keep the level of battery charge level.
In step 106, also can carry out the optional step that changes rotation speed of the fan.Can be based on various conditions, for example by monitoring pin or monitored connection that the state of other assemblies as Parking Brake 36 is learnt such fact of annex, or other, change rotation speed of the fan.For example, when power output connecting pin 32 is not provided with break for high petential, can to major general's fan remain on minimum RPM or more than.Motor racing may not provide enough coolings owing to producing more heat at higher rotating speed, allows engine cooling so change rotation speed of the fan.
What illustrated and described is specific embodiments of the invention, but can expect a large amount of variants and optional embodiment for those skilled in the art.Therefore, the present invention only is subject to claims.
