Abstract
The invention discloses a control system for saving gasoline through the freewheeling of an automobile. Before the automobile is started, an ignition switch is turned on; a setting is set on a setup panel; and ON or OFF is selected. When the ON is selected, a maximum driving speed can be set according to road conditions; when the automobile is accelerated to reach more than or equal to 100 percent of the set speed, an automatic gearbox is shifted to a neutral position automatically; an engine shuts down automatically; and the automobile is in a state of the freewheeling. When the OFF is selected, the engine is started for preheating; the gearbox is shifted from a park position to a reverse position or an automatic position; the automobile is started and accelerated to an ideal speed; the automatic gearbox is shifted to the neutral position manually; and the engine of the automobile shuts down automatically for freewheeling. By adopting the control system for saving the gasoline, an ideal driving speed can be reached by accelerating only 1/3 of time, and the other 2/3 of the time is used for the automatic shut-down of the engine and the freewheeling of the automobile; and thus the control system can reduce the fuel consumption by over 50 percent and greatly reduces exhaust emission.
Description
Technical field
The present invention relates to a kind of autonomous cruise speed system of saving gasoline through freewheeling of automobile.
Background technology
Along with quickening of urbanization process, automobile exhaust pollution is day by day serious; Expanding economy car owning amount is per capita increased sharply rapidly, and the traffic congestion phenomenon happens occasionally, and frequent becomes to wait the long queue of lamp before the traffic lights; At this moment, tail gas is constantly discharged in the running that vehicle motor does not stop, foul air, and the environment of serious harm periphery has become maximum city environmental pollution source.Some experienced drivers are in order to save oil consumption, coast turns off engine after oiling reaches certain speed, the complicated highway section cruising of in the middle of sliding, lighting a fire again, the coast that before seeing traffic congestion or red light, also can turn off engine, the engage a gear operation of lighting a fire again of coasting speed deficiency.Foot brake shakes hands to brake to brake inadequately during parking, and engine ignition travels during green light.Though oil consumption has been saved in operation like this, has reduced the discharging of tail gas, has serious potential safety hazard.Therefore, how just can eliminate safe hidden trouble, save oil consumption, reducing exhaust emissions is the problem that presses for solution.
Summary of the invention
The technical problem to be solved in the present invention relates to a kind of automatic control system for saving gasoline through freewheeling of automobile, and this fuel-saving techniques is easy to implement, and cost is low, has popularization, has a extensive future.
The automatic control scheme that the present invention adopts is: a kind of automatic control system for saving gasoline through freewheeling of automobile comprises: automatic control system for saving (), panel (two) settings such as () speed settings, speed sensor (three), Automatic Transmission (four), Das Gaspedal (five), brake (six) pedal, power-transfer clutch (seven), driving engine (eight), igniting (key) switch (nine) are set.
Before running car, to open igniting (key) switch (nine), upward setting of panel (two) is being set, selection (ON) is opened or (OFF) is closed.Select (ON) to open: can set velocity amplitude 〉=100% o'clock → Automatic Transmission that maximum travelling speed value → car acceleration reach setting from moving neutral gear according to the road conditions of travelling, automotive engine stop working (dormant state) coast → vehicle speed retarding → step on the accelerator Automatic Transmission enter the gear driving engine automatically and light a fire automatically → velocity amplitude 〉=100% o'clock → Automatic Transmission that car acceleration reach setting is from moving neutral gear, automotive engine (dormant state) coast of stopping working.The pedal that touches on the brake, Automatic Transmission enters gear automatically, and driving engine is lighted a fire automatically, and step on the accelerator quickens.Manually hang neutral gear, the driving engine auto shut down is hung the P shelves and is stopped; Select (OFF) to close: engine starting preheating → hang R (reversing) shelves or D (automatically) shelves → starting-up to speed from P (parking) shelves, reach desirable speed → Automatic Transmission and manually hang neutral gear, automotive engine auto shut down (dormant state) coast → vehicle speed retarding → step on the accelerator Automatic Transmission automatically hangs the gear driving engine and lights a fire automatically → and car acceleration reach needed speed → Automatic Transmission and manually hang neutral gear, automotive engine auto shut down (dormant state) coast ... back and forth above the switching reaches the fuel-economizing purpose.When gasoline through freewheeling of automobile, the pedal that touches on the brake, Automatic Transmission enters gear automatically, and driving engine is lighted a fire automatically, and step on the accelerator quickens.Manually hang neutral gear, the driving engine auto shut down is hung the P shelves and is stopped.
Adopt this fuel-saving control system, only 1/3rd times that need travel quicken just can reach desirable moving velocity, two time driving engine auto shut down (dormant state) gasoline through freewheeling of automobile of its excess-three branch can reduce fuel oil consumption more than 50%, has reduced the discharging of tail gas significantly.This fuel-saving control system implementation is simple, convenient, cost is low, has wide application value and market outlook.It is the revolutionary reform in automobile fuel saving field!

The specific embodiment
The present invention is further elaborated below in conjunction with accompanying drawing and embodiment:
As shown in Figure 1: the present invention is a kind of automatic control system for saving gasoline through freewheeling of automobile, comprising: automobile fuel saving autonomous cruise speed system (), panel (two), speed sensor (three), Automatic Transmission (four), Das Gaspedal (five), brake pedal (six), power-transfer clutch (seven), driving engine (eight), igniting (key) switch (nine) are set.
As shown in Figure 2: the automatic control system for saving gasoline through freewheeling of automobile flow process of patent of the present invention:
At first, before running car, open igniting (key) switch (nine), upward setting of panel (two) is being set, selection (ON) is opened or (OFF) is closed.Select (ON) to open: can set velocity amplitude 〉=100% o'clock → Automatic Transmission that maximum travelling speed value → vehicle starting quickens to reach setting from moving neutral gear according to the road conditions of travelling, automotive engine auto shut down (dormant state) coast → vehicle speed retarding → step on the accelerator Automatic Transmission enters gear automatically, driving engine lights a fire automatically → and velocity amplitude 〉=100% o'clock → Automatic Transmission that car acceleration reach setting enters neutral gear, automotive engine auto shut down (dormant state) coast automatically.When sliding, the pedal that touches on the brake, Automatic Transmission enters gear automatically, and driving engine is lighted a fire automatically, and step on the accelerator quickens.Manually hang neutral gear, the driving engine auto shut down is hung the P shelves and is stopped; Select (OFF) to close: engine starting preheating → hang R (reversing) shelves or D (automatically) shelves → starting-up to speed from P (parkings) shelves reaches the desirable manual extension of speed → Automatic Transmission and neutral gear, automotive engine stop working (dormant state) coast → vehicle speed retarding → step on the accelerator Automatic Transmission automatically hang the gear driving engine and light a fire automatically → car acceleration reach needed speed → Automatic Transmission and manually hang neutral gear, automotive engine auto shut down (dormant state) coast ... when gasoline through freewheeling of automobile, pedal touches on the brake, Automatic Transmission enters gear automatically, driving engine is lighted a fire automatically, and step on the accelerator quickens.Manually hang neutral gear, the driving engine auto shut down is hung the P shelves and is stopped.
