Abstract

Provided is an automatic idle-speed shutting and restarting fuel engine vehicle and a shutting and restarting method, wherein the fuel engine vehicle comprises a fuel engine, a starter motor, a throttle, an electricity storage device, a control device and a starting switch. When the control device detects that the speed of a vehicle is gradually reduced to approach zero, the control device will detect the capacity of the electricity storage device. If the capacity exceeds the electricity threshold value required for starting, it will block fuel supply to the fuel engine to shut down the vehicle to meet the environmental protection requirement. When the driver increases the throttle, the starting switch will be automatically driven to allow the electricity storage device to supply electricity to the starter motor so as to restart the fuel engine, thereby reducing the energy waste and air pollution during the idle speed duration of the vehicle. In addition, if the electricity is insufficient, it will not perform compulsory shut-down so as to prevent the problem of starting failure, increasing the driving convenience.

Description

Ignition automatic flameout and restart of fuel engine vehicle and flameout and restart method

The invention relates to an idle engine automatic flameout and restarting fuel engine vehicle and a flameout and restart method, in particular to a fuel engine vehicle which is automatically turned off when the vehicle is idling, automatically restarts when the throttle is increased, and is turned off and restarted. method.

Modern people, whether they are going out for a trip, going out to work or going to work, many people choose to drive or ride a motorcycle as a means of transportation, and there are quite a lot of motorcycles, whether it is a Scooter motorcycle with a front pedal. Or a speed-shifting motorcycle that is riding in a straddle mode is a common type of car.

However, whether it is a car or a locomotive, when driving on the road, there will be a red light pause, or a roadside stop to answer the phone, pause, etc., while the vehicle is not driving, But the engine will still idle at idle. This idle idling situation not only wastes fuel, but also consumes limited resources, and also adds particles in the air, causing unnecessary air pollution. In response to environmental protection, some drivers will manually turn off the vehicle while waiting, until the vehicle is re-started manually, but this is not convenient, and the restart time is too long, increasing driving on the road. Inconvenience.

In order to comply with the trend of environmental protection, the current regulations have been revised. When the fuel vehicle is idle for a predetermined period of time without turning off the fire, it will be punished. Therefore, some operators have proposed relevant research to try to set an idle stop device in the fuel vehicle. When the running vehicle gradually decelerates to a stop, the idle stop device will automatically force the vehicle to turn off, so that the vehicle can automatically turn off when the vehicle is idle. Switch by manual and avoid the touch.

However, in the process of starting the vehicle, the engine must first be driven by an electric motor. It allows the engine to enter a cycle of combustion output. Unfortunately, the battery has limited power storage, especially under the new regulations. It needs to be turned off and restarted. The battery will be more easily drained and the battery life will be shorter. Once the battery is running out of power. By continuing the forced stalling described above, it is possible that the power is exhausted at the time of restart, so that the engine cannot be started.

In addition, the current motorcycles are controlled by microprocessors because of the injection and ignition of the injection engine, and the improved design is too precise to be replaced by the foot. Therefore, most of the motorcycles have not been equipped with a stepping rod. , let alone the launch of the car. Therefore, once forced to stall at an inappropriate timing, it is necessary to bear the risk that the vehicle will be anchored halfway and unable to start.

Moreover, the driving habits of each driving are different, and the standards for idle speed may not be the same, for example, the speed of the vehicle needs to be completely zeroed or lower than the set threshold speed, and how much time is required to maintain the idle speed, even the throttle is operated to How much can be restarted, how to match the driving needs, so that every vehicle with an idling stop device can adjust the internal threshold setting, so that it can be adjusted according to the driver's habits. People are convenient and driving fun.

Moreover, when the relevant parts for the vehicle are slightly damaged due to wear and tear, causing an abnormality at the time of starting, and it is necessary to drive the vehicle to the maintenance place, if the vehicle is in the distance, the vehicle continues to automatically extinguish several times. And start-up, will increase the burden on the parts or institutions to be adjusted or replaced, increase the unnecessary additional damage probability, and reduce the life of the parts; the worst case is that it is too late to replace and damage the road. On the other hand, when the vehicle just starts, if the driver wants to warm the car, temporarily keep the vehicle in the idle state, but it is detected by the idle stop device and automatically turns off, so that the warm-up time is too short to achieve the expected warm-up effect. It is also inconvenient on another level.

On the other hand, when the vehicle is driving on a steeply steep uphill section, although it is still driving, The speed of the vehicle has obviously slowed down. Some idling and flame-extinguishing devices are designed to have a low threshold when the speed threshold is not low enough. As a result, the idling stop device will be misjudged, causing the vehicle to automatically turn off on the uphill section. Sliding down, not only may cause damage due to crashing, it is even more likely to affect the rear vehicles, resulting in more serious casualties.

Therefore, how can an idling and flame-extinguishing device having the storage amount for detecting the power of the battery and determining the starting state of the vehicle can be automatically extinguished and extinguished when the vehicle is in an idle state when the power is not fast enough, or when an abnormality occurs in the startup; The re-starting process allows the driver to have more time to drive the vehicle to the maintenance office, to immediately replace the operation, increase the convenience of driving, reduce unnecessary time waste, and how to avoid being idling when the vehicle is warmed up The problem of automatic flameout detected by the device, how to avoid the misjudgment caused by driving downhill sections, and how to design various threshold values for driving adjustment internal settings, so that the function of idling and restarting can be more suitable for driving. Habits, this will be the focus of this case.

An object of the present invention is to provide a fuel engine vehicle idle-stopping and restarting method for automatically starting a vehicle when detecting an idle speed of a vehicle and detecting that the throttle is re-operated.

Still another object of the present invention is to provide a method for idling and restarting a fuel engine vehicle that has stopped detecting an idling stop when the startup power is insufficient.

Another object of the present invention is to provide a fuel engine vehicle idle-stop and restart method having a vehicle temperature detection and stopping the idle-stop function when the vehicle temperature does not reach the temperature threshold.

Still another object of the present invention is to provide a method for ignoring and restarting a fuel engine vehicle that stops an idling stop function when the starting components of the vehicle are worn out so that the idling stop function is stopped.

Still another object of the present invention is to provide a fuel engine vehicle idling stop and restart method for simultaneously detecting wheel speed and fuel engine speed as a basis for determining the vehicle idling speed and increasing the accuracy of determining the idling speed of the vehicle.

Still another object of the present invention is to provide a fuel-engine vehicle having an automatic ignition stop and a restart that detects an automatic flameout when the vehicle is idling and automatically detects that the throttle is re-operated.

A still further object of the present invention is to provide a fuel-engine vehicle for automatically de-igniting and restarting an idle speed for confirming that the temperature of the vehicle is higher than a normal operating temperature.

Still another object of the present invention is to provide an idle engine automatic flameout and restart fuel engine vehicle that can adjust the respective threshold values according to driving habits.

According to the present invention, a fuel engine vehicle idling and restarting method includes a fuel engine, a starter motor for starting the fuel engine, a throttle for controlling the fuel supply of the fuel engine, a power storage device, and A control device, wherein the idle stop and restart method comprises: a) detecting whether the fuel engine vehicle speed approaches zero; b) determining, by the control device, whether the power stored by the power storage device exceeds a power to activate the starter motor The threshold value; and c) when the power storage device stores power exceeding the power threshold and the vehicle speed approaches zero, the control device intercepts the fuel supply of the fuel engine.

According to the present invention, an idle automatic extinguishing and restarting fuel engine vehicle includes: a fuel engine driving the fuel engine vehicle; a starter motor for starting the fuel engine; and a throttle for controlling the fuel supply of the fuel engine. a power storage for starting the starter motor And a control device that cuts off the fuel supply of the fuel engine when the power storage device stores more than one power threshold and the vehicle speed approaches zero.

Therefore, the fuel engine vehicle and the flameout and restart method designed by the present invention for automatically stalling and restarting idle speed detect the power stored in the power storage device when the vehicle is detected to be idle, and if the power is sufficient to supply the starter motor The drive can make the fuel supply of the fuel engine cut off, so that the idle vehicle automatically turns off, and the power stored in the storage device is detected in advance, which avoids the problem that when the vehicle is automatically turned off, there is not enough power for restarting, and further, when the vehicle During the starting process, if the starting part is worn out due to long-term use, causing an abnormality in the starting of the vehicle, the vehicle is automatically stopped when the vehicle is idling, and a message indicating that the abnormality is activated is displayed on the dashboard, for example, for driving. Allow sufficient time to drive the vehicle to the maintenance office, increase the convenience of driving, and reduce unnecessary time waste caused by the vehicle anchoring on the road. When the vehicle is just starting to warm up, it can detect the current temperature of the vehicle first. When the temperature has not reached the predetermined temperature threshold, the vehicle will automatically stop automatically when the idle speed is stopped, so that the warming process will not be interrupted.

Moreover, in this case, the idle-speed auto-extinguishing and restarting fuel-engine vehicles can be additionally provided with a data output/input for inputting and changing the threshold value, and for a computer connection to adjust the threshold value to achieve idle speed. The timing of the flameout and start can meet the driving habits. In addition, the determination of the vehicle idle speed can detect the fuel engine speed at the same time according to the wheel speed. Therefore, the idle speed condition must be reduced when the wheel speed and the engine speed are simultaneously reduced. Can be established, so whether the vehicle is driving on an uphill section or a downhill section, it will not affect the judgment of idle speed, increase the accuracy of judging the vehicle idle speed, avoid the danger of automatic misfire when the vehicle is misjudged on the uphill section or downhill section, increase For the safety of driving while driving, and to achieve all of the above purposes.

The above and other technical features, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

A first preferred embodiment of the present invention relates to a first embodiment of an engine for idling automatic restart and restart, as shown in FIGS. 1 and 2, in this example, a fuel engine vehicle is an example of a motorcycle 1 including a fuel engine 11 The starter motor 12, the throttle 13, the power storage device 14, the control device 15, and the start switch 16, wherein the control device 15 is exemplified as an engine control device (ECU) in this example, and stores a vehicle speed threshold, a power threshold, and Start the threshold value parameter data.

In the first preferred embodiment of the fuel engine vehicle idle-stopping and restarting method of the present invention, as shown in FIG. 3, initially, as step 301, the motorcycle 1 maintains the normal traveling speed, and is controlled by the control device 15. The current speed of the motorcycle 1 is detected, and the speed detection method of this example is to detect the wheel speed of the motorcycle 1, and then, as in step 302, the control device 15 determines whether the vehicle speed approaches zero and maintains The vehicle speed passes for a predetermined period of time, for example, when the wheel speed is lower than 10Kph as the vehicle speed threshold, and the maintenance time can be set to 5 seconds. If the vehicle speed has not approached zero, then return to step 301 and continue to be judged by the control device 15 Speed of the car.

If the vehicle speed approaches zero and has been maintained for 5 seconds, then in step 303, the control device 15 determines whether the power stored by the power storage device 14 exceeds a power threshold sufficient for starting the motor 12, and the power of the example The threshold value is exemplified as 10.6V. If the stored power has approached the power threshold, then in step 304, the fuel supply of the fuel engine 11 is maintained to maintain the motorcycle in an idle state. If the currently stored power exceeds the power threshold, Then, in step 305, the control device 15 cuts off the oil supply of the fuel engine 11 to automatically switch the motorcycle 1 entering the idle state into Flameout.

When the driving is ready to leave, the throttle 13 is actuated. Therefore, as in step 306, it is judged by the control device 15 whether or not the throttle 13 is re-operated, and the starting threshold of the throttle 13 of this example is the available range of rotation. For example, if the throttle 13 has not been operated, the process returns to step 306 to continuously monitor the throttle 13. If the throttle 13 is operated and the range of rotation exceeds 5%, the control device 15 controls the start switch 16 to drive the power storage device 14 to supply power. To start the motor 12, the starter motor 12 is caused to restart the fuel engine 11, so that the motorcycle 1 switched to the flameout state can be started immediately.

Referring to FIG. 4, the control device 15 of this example can be a control loop, and the same control effect can be achieved by the logic gate control mode, and the start switch 16 can be a trigger circuit directly connected to the throttle valve 13 when When the throttle 13 is activated to the activation threshold, the start switch 16 is directly activated and directly drives the power storage device 14 to supply the starter motor 12.

Of course, the fuel engine car of this example is an example of a motorcycle 1, but in fact, various vehicles with a fuel engine can be applied. Therefore, whether it is a general car, a truck or a bus, the same can be turned off and restarted. Features.

A second preferred embodiment of the present invention relates to a sleek automatic flameout and restarting fuel engine vehicle, as shown in FIG. 5. In this example, the fuel engine vehicle further includes a temperature measuring device 17'. In this example, the control device 15' further includes an alert unit 150', and the alert unit 150' can be exemplified as a dashboard for displaying an alert message, and the control device 15' further stores a normal temperature threshold, a hard-to-start threshold, and an idle threshold. Value information.

In the second preferred embodiment of the fuel engine vehicle idling and restarting method of the present invention, as shown in FIG. 6, initially, as in step 601, when the motorcycle is started, the control device 15' starts to calculate. The start time of the motorcycle, and determine whether the start time of the motorcycle is more difficult The threshold value of the threshold is generated, and the threshold of the hard-to-start threshold in this example can be exemplified as time 20 seconds. If it is exceeded, it indicates that the starting part may be abnormal, and in step 602, the warning unit 150' is driven by the control device 15' to issue a warning message. Even if the motorcycle is still successful in the end, it will be necessary to turn off the monitoring of the idle speed detection and the idle speed, so that the driver can ride the motorcycle to the maintenance office as soon as possible for maintenance.

If the startup is successful within the time when the threshold is difficult to be triggered, and then, as in step 603, the temperature measuring device 17' senses the current temperature of the motorcycle, and transmits the measured temperature data to the control device 15' for judging the current Whether the temperature exceeds the temperature threshold, and the normal temperature threshold of this example is set to 60 degrees. When the measured temperature data has not exceeded the normal temperature threshold, the motorcycle may still be in the warm-up phase, and then it can be returned. Go to step 603 and continue to be judged by the control device 15'. If the normal temperature threshold is exceeded, the idling condition of the motorcycle can be monitored as in step 604.

In order to increase the accuracy of the idle determination, as shown in FIG. 7, as shown in step 605, the control device 15' determines whether the vehicle speed approaches zero, and maintains the vehicle speed for a predetermined period of time, and the maintenance time of this example is also Set to 5 seconds, if the vehicle speed has not approached zero, then return to step 605, continue to determine the current vehicle speed by the control device 15', if the vehicle speed approaches zero, and after a predetermined period of time, then as in step 606, The control device 15' determines whether the rotational speed of the fuel engine 11' is lower than the idle threshold, and maintains the rotational speed for a period of time. If the rotational speed of the fuel engine 11' is still higher than the idle threshold, the process returns to step 606 to continue the control device 15. 'Monitoring, if the speed of the fuel engine 11' is lower than the idle threshold and has been maintained for 5 seconds, then in step 607, the control device 15' determines whether the power currently stored by the storage device 14' exceeds enough for the starter motor 12' The power threshold value of the startup, if the stored power has approached the power threshold, then in step 608, the fuel supply of the fuel engine 11' is maintained to maintain the motorcycle in an idle state. If the currently stored power exceeds the power threshold, then in step 609, the control device 15' intercepts the fuel supply of the fuel engine 11' to allow entry. The motorcycle in the idle state is automatically switched to the flameout state.

Then, as step 610, it is determined by the control device 15' whether the throttle 13' is re-operated. If the throttle 13' has not been operated, then return to step 610 to continuously monitor the throttle 13'. If the throttle 13' is operated, then step 611 is performed. The control device 15' will operate the start switch 16' to drive the power storage device 14' to supply power to the starter motor 12', causing the starter motor 12' to restart the fuel engine 11' so that the motorcycle switched to the flameout state can be activated immediately.

Since this example is combined with the speed of the fuel engine 11' as the idle speed determination mode, when the motorcycle travels on the uphill section, although the wheel speed is slow, the fuel engine 11' will continue to operate to increase the climbing. The required torque, however, when the motorcycle is driving on a downhill section, although the fuel engine 11' reduces the rotational speed because the required torque is reduced, the wheel speed is increased by the downward pressure, so the idle condition is necessary. The speed of the fuel engine 11' and the wheel speed are simultaneously lower than the set threshold value, so that the determination of the idle speed is not affected by the terrain and the misjudgment is made, and the accuracy of the idle speed determination is increased.

In this example, the idle engine automatically extinguishes and restarts the fuel engine car, as shown in Fig. 8, and another data output/input 18' connected to the control device 15' is provided, which can be driven according to the driving habit of driving. The computer connects a signal line to the data output/input 18', and changes the above threshold values, such as relaxing the idle speed threshold, or extending the time for determining the idle speed and the warm-up determination, and changing the threshold makes the driving more suitable for driving. demand.

Due to the idling automatic shutdown and restart of the fuel engine vehicle and the flameout and restart method in this case, the power stored in the power storage device will be detected first, and the remaining power must be sufficient to supply the start, so that the function of automatically extinguishing when idling can be started, which can be avoided. When the vehicle is automatically turned off, it can no longer be started and the problem is broken on the road, which increases the convenience of driving, reduces unnecessary time waste, and, when the vehicle Before the vehicle is started, if the starting parts are worn out and the vehicle is not easy to start, the vehicle's idle automatic ignition function can also be automatically cancelled, and the message of starting abnormality can be displayed on the dashboard, so that the driving can have more sufficient time to drive the vehicle. Drive to the repair office. Or, when the vehicle is just starting up, it can detect the temperature of the current vehicle first. When the temperature reaches the predetermined temperature threshold, the vehicle idle speed can be detected again, so that the vehicle will not be misjudged even if it is warmed up. The engine is automatically turned off at idle speed, so that the warm car will not be interrupted.

Moreover, in this case, the idle-speed auto-extinguishing and restarting fuel-engine vehicles can be additionally set up with a data output/entry port and connected through a computer for inputting and changing the threshold values, which can be adjusted according to driving habits, so that the idle speed is extinguished and The function of restarting can be more in line with the driving habit of driving. Moreover, the judgment of the vehicle idle speed can simultaneously detect the fuel engine speed and the wheel speed, so that the idle speed condition must be established when the wheel speed and the engine speed are simultaneously reduced, so that The judgment of idling speed will not be misjudged by the influence of the terrain, increase the accuracy of the judgment of the vehicle idling speed, avoid the risk of automatic misfire when the vehicle is misjudged on the uphill section or the downhill section, and increase the safety of driving while driving. All of the above purposes.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All should remain within the scope of the invention patent.
