Description

Method of operating a locomotive

The present invention relates to a method and apparatus for operating a locomotive.

"Motorcycle" means all types of power vehicles in a single row of two wheels, with or without Knieschluss (also known as straddle locomotives or mounts). Most of today's locomotives are powered by air-cooled (and some water-cooled) four-stroke engines. The second-stroke locomotive that was flooded earlier was mainly used today for powerful locomotives.

To start and stop the drive engine, a so-called start switch is generally used. When the ignition is activated or the ignition key is turned, the rider can activate the start switch to start the engine.

In the past many years, the application of start/stop systems in the automotive sector has increased significantly, citing a reduction in CO _{2 and a} reduction in total operating costs, as well as a “green image” of the Cavaliers and the market. In the start/stop function, the engine of the internal combustion engine of the car is turned off in the stationary phase of the vehicle, and is automatically restarted before the start of travel (LosFahren).

A device for starting and stopping an internal combustion engine of a motor vehicle is disclosed in the document DE 10 2010 029 210 A1, which comprises a first switching means and a second switching means, wherein the first switching means can assume a first and a second state . The second switching means is also true. Depending on the state of the switching means, there is an electrically conductive connection between an electromechanical device and an electrical energy storage device.

In the field of locomotives or two-wheelers, the development of start/stop systems is at the forefront. A type of starter/stop vehicle that can only be purchased today is a Roller with a stepless coupler. In particular, in the field of locomotives with hand gears, such start/stop vehicles are still not available. In such locomotives, the engine of the locomotive differs from the engine of the car in that it is activated by pressing a button (key) or by actuating the start switch. In order to automatically restart after a stop phase, the state of the starter switch in the motor control unit has to be processed. Conversely, a switch is usually provided in the automotive field to activate or deactivate a start/stop action, and in the second-wheel field, the start/stop system is unacceptable to the customer to deactivate the start/stop function.

In some countries where fuel costs are relatively higher than, for example, European standards, in the case of locomotives, the engine is normally turned off by hand after a short idling phase and then manually started.

It should be noted that if the locomotive or motorcycle is mentioned below, it also includes a power tricycle, such as a power rickshaw (powered tricycle).

The advantages of the starting system of the above-mentioned vehicle are wear reduction and increased comfort. Since the operational strategy known in the field of starting/stopping in the automotive field cannot or cannot be meaningfully transferred to the two-wheeled vehicle, an operation strategy for the two-wheeled vehicle is to be developed. .

Based on this background, the method according to item 1 of the scope of application of the patent, and the subsidiary and the specification with the scope of the patent application are proposed.

In this way, the existing starter switch is used to start or stop the engine on the one hand, and the start/stop mode is activated or deactivated on the other hand.

It is known that deactivating the start/stop function with an additional switch adds extra cost, requires more space on the handlebar, and requires additional inputs at the control unit, which can be activated without additional switches. / Stop function activation and deactivation.

The present invention recognizes that the additional switch is used to deactivate the start/stop function with additional cost and more space on the handle, as well as an additional input on the control unit. With the above device, the start/stop function can be activated and deactivated without an additional switch.

Other advantages and designs of the present invention are found in the description and the drawings.

Obviously, the features described above and below may be used not only in the combination described above, but also in other combinations or separately without departing from the scope of the invention.

1 is a diagram of a possible implementation of the method; FIG. 2 is a circuit device according to the prior art; FIG. 3 is a circuit device for implementing the above method; FIG. 4 is another method for implementing the above method. Possible circuit arrangement.

The present invention is represented by the embodiments shown schematically in the drawings and is described below with reference to the drawings.

Figure 1 is used to illustrate the state of ignition (10), that is, start (12), turn off (14); engine state (20), start (22) / turn off (24); start switch state (30) ; that is, start (32) / turn off (34); and the state of the start / stop function (40), that is, start (42) / turn off (44). In addition, a first area (50) and a second area (52) are displayed, and the start switch (30) can be designed as a start button.

After the ignition is started (for example, the ignition key is turned), the locomotives are "started in the start/stop function (40) state" or "turned off in the start/stop function (40) state" according to the OEM's intention. In the "Start/Stop function (40) state is turned off", the engine (20) can be started in the following manner: The starter switch (30) is pressed for a valid period of time, for example 1000 milliseconds. This length of time is necessary to remove the start switch (30) from the entrellen and to avoid unintentional erroneous actions. The action is reactivated while the engine (20) is running to turn the engine (20) off again.

The figure shows that each of the first regions (50) of the starter switch (30) acts twice for a first period. In the second region (52), the start switch (30) first operates as a second period, and then the action is timed as a period, and the second action is again. Acting the start switch (30) for the first period of time causes the engine (20) to be turned ON or OFF, that is, to start or stop. Acting the start switch (30) for the second period of time causes the engine (20) to be turned ON or OFF and the start/stop function is turned ON or OFF, that is, activated or deactivated. As shown, the first period and the second period are different. In this case, the first period is smaller or shorter than the second period. Therefore the second period is larger or longer than the first period. Of course, the first period (which is related to the ON or OFF of the engine (20)) can be made more than the second period [it is related to the ON or OFF of the engine (20) and the ON or OFF of the start/stop function (40)]. Big. More periods than two can be defined, each of which is related to a different action.

Therefore, the engine (20) is started by a long action of the start switch (30) (this corresponds to the second period), for example, 2 seconds. In addition, the start stop function or the start/stop mode is turned ON, and when the start/stop mode is ON, the engine (20) can be subjected to a short action (this corresponds to the first period) OFF, as long as the motor is automatically stopped (for example, cut into idling) If the conditions are not met. When the engine (20) is turned off, the start switch (30) is restarted for a short action (for example, less than 2 seconds), and the engine (20) can be restarted as long as the motor is automatically started (for example, the clutch is pulled). If satisfied, as shown in the second area (52).

Thus the action of the diverter switch (30) is used to represent a particular driver command. In this way, the period of the action is analyzed, and the state is changed, for example, starting/stopping active. If this method is not used, the start switch (30) can also be coded in a certain order to represent the desired command.

Corresponding to this, it is possible to activate or deactivate the start/stop mode by a longer action (for example more than 2 seconds) of the start switch (30) regardless of whether the engine is ON or OFF, regardless of the actual engine state. However, it is not possible here to change the start/stop state → start/stop ON or OFF without simultaneously changing the state of the engine (20) - engine (20) ON or OFF - otherwise, the engine (20) The state - engine ON or engine OFF - changes without changing the start/stop state.

In addition, several modes → start/stop OFF, start/stop mode, and sport mode can be used to encode with the start switch (30). The method is to select a sufficient length of time, for example, a simple engine start of 0.1 second or Simple engine stop, 2 second start/stop ON or OFF, 5 second motion mode ON or OFF.

Generally, a driver information such as a LEO form or a display device can be set in a combination tool. If several modes are coded by the start switch (30), a driver information is absolutely required, for example, according to the selected mode. One of the different flashing messages of the LED.

With this optical display, it is also possible to use different flicker model displays to indicate that the locomotive is in the first start or in a stopped state (in which, for example, can be restarted by pulling the clutch) or in the engine when the engine (20) is running (20) In principle, the start/stop function can be tolerated during operation, in other words, whether the engine (20) is warm enough, whether the battery is sufficiently charged, etc.

A display (such as an LED) can be used to send a request for restart to the driver - if the condition of autonomous restart is used, if the battery is discharged too much and the driver does not know, a reliability can be achieved in a simple manner, and It is as reliable at autonomous start-up, without the need for high cost for the driver to detect.

In Fig. 2, the circuit arrangement for wiring the starter switch and the starter relay according to the prior art is indicated by the figure number (70). The figure shows a moving motor (72), a moving switch (74), an engine control device (76) (in which a central processing unit (CPU) (78) is provided), a first switch (80), and a first Two switches (82).

Different from today's hardware wiring for electrical switches and electrification relays (where the engine control device only uses a relay to release the starting action), as shown in Figure 2, the operating strategy shown here will be used to start The state of the switch (74) is read into the engine control device, and the starter relay is switched off by the engine control device, as shown in FIG.

3 is a circuit device for mating a starter switch and a starter relay to implement the above method, and is generally represented by a figure number (100). The figure shows a moving motor (102), a moving switch (104), and a first switch. (106), a second switch (107) and an engine control device (108), wherein the engine control device (108) is provided with a CPU (110) and a transistor (112), and the transistor (112) controls the first Switch (106).

The illustrated device (100) is necessary to enable a start by different conditions (clutch pull, release the brake...) without being affected by the start switch (104), and using the start switch when the engine is running It stopped.

In this type of wiring, a method can also be used in which the engine is started and the engine is stopped by actuating the start switch (104), thereby enabling the driver to automatically or automatically operate the operation section as described below while driving. And the choice between the above operational strategies.

The following describes the different operating strategies, which can be used to illustrate the start/stop function in the locomotive. Different operating strategies can be applied to strategies that are less comfortable but less costly than standard systems without start/correct functions, especially for development homes, or for no start/stop work The standard system of energy has higher comfort (as required by European motorists) and a higher cost strategy.

Four other operational strategies have been developed and are described below individually.

In an operation strategy called "automatic stop", the engine is automatically turned off due to different conditions, such as speed, drive coupling separation, etc., and then restarted by the start switch action.

The purpose of this operational strategy is to achieve a start/stop function with minor changes to existing systems.

In order to stop the engine automatically, it must be driven at a speed above the effective threshold from the last start, for example 10 km/h, to avoid the engine being turned off during the shifting operation (Rangierbetrieb), here from the last engine It must be passed for a valid period of time (for example, 5 seconds) to avoid frequent starting (frequent starting will cause high load on the battery and starter) and make driving feel uncomfortable. If the above conditions are met and the vehicle speed is in the drive open state (ie, pull the clutch or enter neutral) for 0 km/h, the engine is turned off.

In this mode of operation, the vehicle speed that is not necessarily provided in the engine operating device and the speed of the engine control device are read into the engine control device, and whether the drive connection is open can be reliably: if the speed is 0 km/h. If the rotational speed is greater than 0 rpm, the drive coupling must be opened. To apply this operational strategy to the above embodiment, the start control of Fig. 2 is sufficient.

If this method is not used, the engine should be stopped, similar to the operation strategy described below: "Start/Stop - Start in Neutral" is only in neutral and the clutch is closed. To do this, the state of the clutch and the neutral position of the engine control unit must be analyzed. In addition, the "engine stop" can be achieved by the start-up switch action similar to the operation strategy "automatic start" described below, for which the starter control of Fig. 3 is required.

In summary, in this operation strategy, the engine must be stopped. The maximum speed since the last start is greater than 10 km/h. The last start time is more than 5 seconds. The drive coupling is disconnected and the clutch is pulled into neutral.

The operating conditions are 0 km/h.

The engine is started under the condition that the drive coupling is disconnected, the clutch is pulled, and the neutral is entered.

The operating conditions are: start switch action.

In the operation strategy called "automatic start", when the drive is open and the engine is running, the engine is stopped by the start switch action. Therefore, the start switch has two functions, each of which is stopped or started according to the state of the engine. The starting system is achieved by different conditions, that is, pulling the clutch, releasing the brake, etc., or starting the switch when the engine is turned off and the driving open circuit is opened.

The purpose of this operational strategy is to enable the driver to utilize the start/stop system with maximum control while providing high comfort. Mainly, in the traffic of big cities, often the locomotive knights often have to drive past the parked cars when they are in front of the yellow light. They stop at the stop line until they finally stop. If you stop for a short period of time during this control, the engine must not be automatically turned off because the Cavaliers will then drive again.

If the vehicle speed is below a valid threshold, for example 5 km/h, and the drive is open, the clutch is pulled, or enters neutral, the driver can activate the starter switch to extinguish the engine. When the engine is turned off, the rider can disengage the clutch. open. In this way, the restarting mechanism is then required to pull the clutch again. If the knight pulls the clutch while the engine is stopped, the engine can be operated by rotating the throttle for a short time or releasing the front brake. In addition, the engine can be opened when the drive is opened. Start by operating the start switch.

In order to stop the engine by the start switch action, start control according to Figure 3. system. In order to stop below the speed limit, the speed of the vehicle must be known in the engine control. To allow the engine to start automatically, the clutch position (clutch open, clutch at the friction point, clutch closed) must be known. This requires two sensors (for example, 10% and 90% of the clutch path). In order to start the engine with the front wheel brake release, the brake light must be analyzed or the brake pressure detected in the engine control unit. It may be necessary for other functions, in order to be able to borrow the throttle to start the engine, so the throttle position (intake) (English: choke) must be known in the engine control device, which is necessary.

In summary, in this operation strategy, the engine is stopped under the condition that the vehicle speed is lower than 5 km/h, and the time from the last start is more than 5 seconds, the drive coupling is disconnected, the clutch is pulled, and the neutral is entered.

The operating condition is the starter switch action.

The engine is started under the condition that the clutch is relaxed during this engine phase.

The operating condition is: the clutch is pulled again.

Another alternative condition: the clutch is held while the engine is stopped.

In this way, the operating conditions are: turning the throttle or front wheel brake release or starting switch action.

In an operation strategy called "Start/Stop - Stop in Neutral", the engine is automatically turned off when the stop is switched in neutral and the clutch is released, and the restart is achieved when the clutch is pulled again.

The purpose of this operational strategy is to transfer a car start/stop related system to the locomotive.

Be careful: for this operating strategy, up to the brake light sensor or brake pressure The sensor is required for the same sensor device as in the "autostart" operating strategy.

In summary, in this operation strategy, the engine is stopped under the condition that the vehicle speed is equal to 0 km/h and enters the neutral position.

The condition of the action is: the clutch is relaxed.

There are no conditions for engine start.

The action factor is: Pull the clutch back.

The operation strategy called "Start in Gear" is a combination of the strategies "Auto Stop" and "Auto Start".

The purpose of this operational strategy is to implement an intuitive start/stop system in the locomotive (where no neutral is required to automatically turn off the engine). Unlike a car, it is often difficult to get into neutral when the locomotive is located because it is located Between the first and second gears, so usually (especially at a shorter stop) can enter a gear.

Since it is a combination of two operational strategies, the required sensor devices are also combined by the sensing devices of the two strategies.

Input values that cause a stop in all operational strategies are also considered: engine temperature, battery state of charge (which can be evaluated according to a model or detected with a sensor), cooling ventilator status (ie cooling and venting) The engine does not stop when the unit is running, (because the battery is over-required), and other measured values.

In addition, a driver's detection can be implemented, and the start of the engine control device can be performed without the knight's previous action. The reason can be: the engine stop phase lasts too long (battery load), and the car is empty rolling (Rollendes Fahrzeug), the engine temperature is too low.

Figure 4 shows a circuit arrangement (indicated generally by 150) for implementing the method, The figure shows a moving motor (152), a clutch switch (154), a neutral switch (156), a first starting relay (158), or a combined release relay, a second starting relay (159), a display a lamp (160), a moving key (162), and an engine control device (164) having a CPU (166), a first transistor (168) of a control device, and a final stage of the control device A second transistor (170).

If the display light (160) is not used, the optical display can also be used to give information to the knight, such as a sound display means.

With the start button (162), the start or stop is triggered by the knight and read into the control device (164).

Examples of starting are: the trigger signal is processed in the control device (164), and when there is a starting request and a starting action is made, the control circuit of the first starting relay (158) is grounded by the final stage transistor (120). . Since there is a "electric clip" (15) at the positive end of the control line, the first start relay is turned on. The positive end of the second starter relay (159) is also connected to the electric clip (15). The use of switch/diode combinations (54) and (156) (as long as they are closed, ie, cut into a neutral or pull the clutch so the drive is open) only causes grounding. Therefore, the second start circuit is turned on and the starter motor (152) is energized. The state of member (154) (156) or (156) is read back to control device (164) for "release" or for diagnosis. Basically, a brake light switch and/or a clutch switch and/or other sensor signals and/or status values can be analyzed.

The ultimate transistor (170) is switched to non-conducting, in other words, when certain edge conditions are met, the first start relay (158) and the second start relay circuit (159) are turned off and the starter motor (152) is inactive. For example, the control device (164) is detected until the start is completed, reaches a speed, or is synchronized. The "stop" is triggered by the action of the start button (162). Here, the state of the member (154) (156) (158) is considered, and then the engine is stopped, for example, the fuel injection is decontaminated.

With the ultimate transistor (168), the state or mode of the vehicle, such as restart requirements, start/stop activities, etc., can also be output.
