Abstract
The invention relates to an automobile idle speed control device with a fuel saving function, which comprises a gear detection device, an idle speed control device and a central control circuit, wherein the gear detection device is used for detecting the gear state of an automobile; the idle speed control device is used for switching idle speed; the gear signal output end of the gear detection device is connected to the input end of the central control circuit; a judgment and control signal of idle speed adjustment is made by the central control circuit according to gear changes in the automobile running process; the control output end of the central control circuit is connected to an idle speed switching device; and the idle speed of an engine is adjusted by the idle speed switching device through controlling an engine air damper. The automobile idle speed control device with the fuel saving function has the significance that the idle speed is reasonably adjusted according to the running state of the automobile so as to achieve the environmental-protection effects of saving fuel and reducing pollution emission, and moreover, the normal running of the automobile cannot be influenced.
Description
Technical field the present invention relates to a kind of electric control device of motor car engine.
Consumption oil was big when the background technique auto idle speed was high, particularly went in the city, ran into red lights such as traffic congestion, the more wastes of fuel oil when idling is high.Turn down idling and can reduce consumption oil, but low idling particularly can cause job insecurity during low speed driving at cruising, even dead fire.Existing technology does not solve this contradiction.
Summary of the invention the present invention seeks to disclose a kind of auto idle speed control gear with energy-saving function.
The present invention includes and be useful on the gear detection device that detects the automobile range state, the idle speed controller that is used to switch idling; And central control circuit; It is characterized in that the gear signal output terminal of gear detection device is connected to the input end of central control circuit; Central control circuit is according to the gear change in the automobile running; Make the judgement and the control signal of idling adjustment, the control output end of central control circuit is connected to the idling COMM communication, regulates engine idle by the idling COMM communication through the control to engine air throttle.
Described central control circuit carries out work according to following logic: the gear change that detects automobile running; As vehicle be in go shelves or retreat shelves, then make motor by normal idle running; When being in neutral gear or park, then,, then make motor by slow idling if be neutral gear or park always at time T continuous detecting gear in the cycle like vehicle; And continue to detect the gear situation, when shelves or reverse gear are gone in the vehicle entering, make motor recover normal idling immediately, and return beginning, periodic duty.
Described gear detection device is the device whether a detection automobile is in neutral gear or park.
The present invention reasonably adjusts idling according to the gear change of automobile running: when vehicle is in neutral gear or park, turn down engine idle to subtract low oil consumption; When shelves or reverse gear are gone in the vehicle entering, recover normal idling immediately, do not influence normal vehicle operation, its meaning is to reach fuel-economizing and the environment protection effect that reduces discharging.
Description of drawings Fig. 1 is a working principle skeleton diagram of the present invention.
Fig. 2 is the working procedure flow chart of central control circuit
Embodiment describes the embodiment of the invention with reference to the accompanying drawings:
Among Fig. 1, gear detection device is used to detect the range state of automobile, can only detect it and whether be in neutral gear and park, also can be directly connected in the gear display circuit for the automobile that has gear to show and obtain gear signal.This signal is delivered in the central control circuit.The idling COMM communication adopts an electromagnetic valve; Be connected on the closure control loop of motor, thereby control the mode that air inflow is controlled idling through closure, automobile is with normal idling work during unlatching; Automobile reaches the fuel-economizing purpose with low idling work when closing.
Central control circuit can adopt Analogical Electronics or microcontroller circuit, also can be with automobile computer as one.Central control circuit is specially: the gear change that 1, detects automobile running to the detection of automobile gear situation, judgement and to logic program such as Fig. 2 that engine idle is adjusted; 2, be in forward gears or retreat shelves like vehicle, then make motor by normal idle running; When 3, being in neutral gear or park like vehicle, the T that then picks up counting at T continuous detecting gear in the cycle, if vehicle gets into go shelves or reverse gear, returns the 1st; If be neutral gear or park when 4, timing reaches T, then make motor turn down idle running always with fuel-economizing; 5, when slow idling, continue to detect the gear situation, get into go shelves or reverse gear, make motor recover normal idling immediately, and return the 1st like vehicle.Periodic duty as stated above.Can not adjust idling when the purpose of timing T is Vehicular shift or of short duration process neutral gear or park, the idling adjustment of avoiding not having the fuel-economizing meaning too frequently takes place, and T is desirable several seconds generally.
