Description of the Invention: [Technical Field] The present invention relates to a method for idling and starting control of a vehicle, and more particularly to a method for controlling a flameout and starting action of a locomotive at idle speed [Prior Art] Locomotives in Taiwan The density is about 330 vehicles/Km2, which is far higher than that of automobiles. It is one of the main sources of air pollution. Moreover, the traffic lights in the urban area of China are densely covered, and the high-concentration exhaust gas emitted by the locomotive at idle speed is a serious pollution to air quality. . In order to reduce environmental pollution, in addition to actively developing the hybrid power system of the locomotive, the implementation of locomotive idle speed bonfire is also one of the primary goals of reducing exhaust emissions. Although the government has actively advocated the idling bonfire policy, it has not been fully implemented. “Because the current city (4) locomotives are out of flames and there is no tree-touching juice” can only rely on the driver to control the bonfire via the I/G switch. In other words, in the case where the control parameters of the currently locomotives are not changed, it is not easy for all drivers to implement the red light when the locomotive is turned off. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a vehicle 怠 frequency fire and start = method, which can automatically control the vehicle offering and starting action in an idle state to save fuel consumption and reduce air pollution. The purpose of this month is to provide a vehicle with an idling total fire and start up. 201102286 Control Method' The automation of the vehicle's idle speed is more flexible by judging driving information, which further enhances the overall energy saving effect. Another purpose of this U is to provide a vehicle idling and start control method to reduce air pollution. In order to achieve the foregoing object, the technical means and the efficiencies achievable by the technical means include: (4) 'Determining whether the throttle opening of the vehicle is less than 2 degrees and the lower limit is less than the margin. Under the thief, the heart rate is judged to read 'H speed judgment tilt, whether the vehicle speed of the vehicle is less than the lower speed limit of the vehicle, whether the engine speed of the vehicle is greater than - the speed limit value and the engine temperature of the vehicle is touched Whether the operating temperature is reached. If the vehicle speed is less than the lower speed limit of the vehicle, the engine speed is greater than the lower speed limit, and the engine temperature meets the operating temperature, a buffering time determining step is performed, and the buffering time determining step is determined. Whether the elapsed time after satisfying the rapid judgment t-threshold condition is greater than or equal to - the buffering time value 'the right _ _ greater than or equal to the buffering time value after the idling determination step condition is reached, the difficulty-engine stalling step; the engine The flameout step controls the vehicle engine to execute the flameout, and returns to the opening degree after completing the engine bonfire, and according to the opening degree between the vehicles Judgment whether to restart the engine. Through the above-mentioned vehicle speed filling and start-up control method, the fire and start-up action of the vehicle can be automatically controlled to save fuel consumption and low air pollution. The throttle opening is less than 2%, the vehicle speed is lower than 2km/hr, and the engine speed is higher than 1200ipm ’ while the engine temperature is turned to the temperature, and the time of the 201102286 is 5 seconds, that is, the flameout action is performed. The start action is performed when the throttle opening is higher than 2% and the engine speed is lower than 1200 rpm. Therefore, the flameout and start-up action of the vehicle can be automatically controlled, so that the overall energy-saving effect is further improved. Further, the idle-speed flameout condition of the present invention must simultaneously satisfy that the vehicle speed is less than the lower limit value of the vehicle speed, and the engine speed is greater than the lower limit value of the speed. And the engine temperature meets the working temperature. In other words, when the vehicle engine does not reach the working temperature, the automatic flameout action is not performed, and the engine can be prevented from repeatedly extinguishing and starting when the operating temperature is not reached, and more combustion is not discharged. Complete fuel gas' to avoid air pollution. BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features, and advantages of the present invention will become more <RTIgt; The idling stop and start control method is to read the traffic information of the vehicle's throttle signal, the engine's throttle opening signal, the engine speed signal, the speed signal and the engine temperature, and control the vehicle's flameout and start action after synthesizing the driving information. . Please refer to FIG. 1 for the control flow chart of the idling stop and start of the vehicle of the present invention, which comprises: integrating the throttle signal of the vehicle, the throttle opening signal of the engine, the 51 engine speed signal, and the engine control benefit 10 Driving information such as speed signal and engine temperature. The opening degree determining step η, the signal controller 10 receives the 201102286 throttle signal of the vehicle, and the throttle signal determines whether the throttle opening of the vehicle is less than a lower limit of the opening degree. If the determination is YES, indicating that the accelerator opening of the vehicle is at the lower limit of the opening degree, the idle determination step 21 is performed. If the determination is "NO", the throttle opening of the vehicle is greater than the lower limit of the opening. Then, the indexing speed determination step 12 is performed.

Ρ Condition 2, it is judged that the idle speed is satisfied. The determining step 21 is broken as "a #夺间疋 is greater than or equal to a buffering time value. If the buffering time/car is sufficient, the above-mentioned idle speed determining step 21 condition exceeds the condition that the vehicle assists the second two:::::: 23, if the judgment is "No", ^, glI..π„~k determines that the condition of step 21 does not exceed the buffer time value' then returns to the degree_step u. The other: 1 after the engine step 23 completes the flameout action of the vehicle engine, ', 仃 flameout confirmation step 24 The engine flameout confirmation step 24 201102286 re-receives the engine speed signal through the signal controller 10, and confirms whether the engine speed of the vehicle is less than the lower speed limit value. If the determination is "Yes", the engine speed of the vehicle is indeed If the vehicle engine engine has entered the engine flameout state, it returns to the opening degree determination step U. If the determination is No, the engine speed of the vehicle is still greater than the speed lower limit value, indicating that the vehicle engine is The engine is not extinguished step 23', and the engine is turned off. Step 23: The above is the step of completing the engine flameout action of the idle stop control method of the present invention. Otherwise, if the engine engine is turned off after the engine is turned off, the valve is returned to the opening degree. Step U, and determining whether to restart the vehicle engine according to the throttle opening degree of the vehicle, the steps of the starting method include: In the opening degree determining step 11, if the determination is "NO", indicating that the throttle device of the vehicle controls the accelerator opening of the vehicle to be greater than the lower limit of the opening degree, the execution engine speed determining step 12 is performed by the engine speed determining step 12 The signal controller 1 receives the engine speed signal and determines whether the engine speed of the vehicle is less than the speed lower limit. If the judgment is "Yes", it means that the engine is in the flameout state, then the engine start step 13 is executed, and the engine is started to be ignited. If the determination is "No", the vehicle engine is still in the startup state, and then the return degree is judged. Step 11. In addition, when the engine start step 13 completes the start of the vehicle engine, the system additionally performs the engine start step M, and re-receives the bow engine transfer number through the job number controller, and determines the engine speed of the vehicle. Whether it is greater than the lower limit of the speed. If the determination is "YES", it means that the vehicle engine has completed 201102286, and then returns to the opening degree determination step 11. If the determination is "NO", it indicates that the vehicle engine has not completed the startup, and the startup time determination step 15 is executed. After the engine startup confirmation step 14 confirms that the vehicle engine has not completed the startup, the startup time determination step 15 repeats the execution of the engine startup step 13 within a preset start time value to continue the ignition start of the vehicle engine. Until the startup time determination step 15 repeatedly executes the engine startup step 13 to exceed the startup time value, the startup number determination step 16 is executed. Further, if the engine of the vehicle completes the ignition during the execution of the engine start step within the 戎 start time value, the return degree determination step u is returned. Next, the above-described startup time judging step 15 judges whether or not the execution engine startup step 13 exceeds the startup calorie number. The number of activations depends on whether the number of execution engine startup steps 13 is greater than or equal to the number of startup times. If it is judged as "Yes", it means that the number of times the engine start step η has been executed has exceeded the upper limit of the number of starts, and (4) itself can be excluded. Therefore, the abandonment start step 17 is performed, and if it is judged to be ":" the door indicates that the execution is performed. The number of times the engine starts the step 13" value, then the step 13 continues to execute the engine's point two-motion upper limit oil "turning to - the speed of the horse is only the implementation of the car computer, the driving computer calculates the car Two = two = after the number is given, the vehicle is driven to receive the control signal from the computer. The degree of throttle opening is less than - open, if the range of 201102286 is 1 to 100% The lower limit of the opening degree of the embodiment is preferably 2%. When the throttle opening is less than 2%, 'the vehicle may be in a state of static or no power demand after being calculated by the driving computer. The engine is not required to provide power, and when the throttle opening is greater than 2%, it indicates that the vehicle may have a large power demand, and the driving computer outputs a control signal to drive the engine to output power. The determining step 11 detects that the accelerator opening degree of the vehicle is less than 2%, indicating that the vehicle does not need the engine to provide the power output, and then performs the idle speed determining step 21. The throttle opening step is determined by the opening degree determining step U撷. When the degree is less than 2%, the idle speed determining step 21 simultaneously determines whether the vehicle speed of the vehicle is less than the vehicle speed lower limit value, whether the engine speed is greater than the speed lower limit value, and whether the engine temperature has reached the operating temperature. The purpose of the vehicle speed and engine speed condition is to determine whether the vehicle is in a state of being stationary or already stationary. The purpose of determining the engine temperature condition of the vehicle is to determine whether the engine has reached the operating temperature to determine whether to perform the engine flameout action. Because, when the engine temperature of the vehicle does not reach the working temperature, the combustion efficiency of the fuel is very low, and the catalytic converter of the vehicle has not yet begun to function. If the engine is repeatedly extinguished and restarted in this case, Instead, it will generate more exhaust emissions, causing air pollution, so the engine temperature When the working temperature is not reached, the automatic flameout operation is not performed. The lower limit of the vehicle speed in this embodiment is preferably selected to be 2 km/hr, and the lower limit of the transfer is preferably selected to be 1200 rpm, and the preferred range of the operating temperature is The value is according to the type of vehicle and the amount of engine exhaust, and there are different preferred operating temperature range values. When the vehicle speed is lower than 2km/hr, the engine speed is higher than uoorpm, 201102286 f = degree _ station for temperature correction, the car domain The speed-of-speed state in the start of the material engine' and the opening degree judgment step u have judged that the engine is in a state of not requiring + power output, and represents a condition that the flameout has been satisfied.

The above state is the vehicle_bonfire control method of the present invention. In addition, the buffer time value of the buffer time judging step 22 is the buffer side to prevent the vehicle from stalling when the engine is stationary. After the engine stalling step 23 completes the flameout action, the engine flameout confirmation step 24 is step-by-step to confirm whether the engine speed of the vehicle is below the speed lower limit value, in order to determine whether the engine is successfully turned off. Further, the lower limit of the rotational speed of this embodiment is preferably selected to be 12 rpm. When the engine speed is still higher than 1200 rpm, it means that the flameout action is not executed successfully, the engine is still not extinguished. 'The engine must be returned to the engine. Step 23 repeats the execution of the engine flameout. When the engine speed is lower than 1200 rpm, it indicates that the engine has gone smoothly. When the flame is extinguished, the opening degree judgment step 11 is returned. The opening degree judging step 11 detects that the accelerator opening degree of the vehicle is greater than 2%, indicating that the vehicle may have a large power demand, and executes the engine speed judging step 12. Further, the engine speed determining step 12 further determines whether the engine speed of the vehicle is less than the lower limit of the speed, and the purpose is to determine whether the engine is in the starting state, and the lower limit of the speed is preferably selected to be 1200 rpm. When the engine speed is lower than 1200ipm, it means that the engine is not started. When the engine speed of 201102286 is higher than the pre-release, the job is recognized as running. If the engine speed lining step 12 judges _ _ light number is greater than 12 〇〇 ah, indicating that there is no need to restart (four), then return to the opening step n. If the engine speed determination step 12 determines that the engine speed signal is less than the deleted rpm, the engine is not started, and the engine engine is started. The above state is the starting method of the vehicle of the present invention in the unpowered assist state. After the engine start step 13 completes the start action, the engine starts to confirm that the vehicle's (four) speed is higher than the turn I1! The driver successfully starts. Moreover, the lower limit of the rotational speed of the embodiment is preferably selected as Cong_. When the engine speed is higher than the table, it becomes passive (four), the bribe degree judgment step is re-reviewed, and the vehicle condition is monitored at any time. When the engine speed is still lower than (four) rpm, w, then the start action of the table 7^ is not executed successfully, the engine is still executed. It is not necessary to continuously execute the engine start step 13, and the step 15 is judged. In the f-commissioning start-up judging step 15, it is judged that the execution engine start step 13 preferably selects i = A or equals - the start time value. Ϋ3' The startup time value is less than when the execution engine startup step 13 is less than ········································· Step 16 then judges to execute this! | Engine start step 13 "Car 1 good equals - the number of starts the upper limit.
