When the diesel train transitions from electric braking to coasting, energy previously consumed or fed back by the electric braking system is suddenly transferred to the powertrain, causing significant fluctuations in engine speed and impacting engine life.

[0008] According to an embodiment of the present disclosure, the control method of the diesel locomotive further includes adjusting the engine speed of the diesel locomotive to the idle speed when the current operating state of the diesel locomotive is a coasting state and the duration of the current operating state exceeds a predetermined time threshold.

[0009] According to an embodiment of the present disclosure, a second trend graph of changes in the engine load rate of the diesel locomotive over the running time is obtained; and a predetermined time threshold is determined based on the second trend graph.

[0041] It should be understood that Figure 1 The number of terminal devices, networks, and servers in the embodiment is merely illustrative. Any number of terminal devices, networks, servers, and internal combustion locomotives may be provided as required.

[0042] Figure 2 The flowchart of the control method of the internal combustion engine vehicle according to the embodiment of the present disclosure is schematically shown. Figure 2 As shown, the method includes operations S201 to S204.

[0043] In operation S201, the current operating state of the diesel locomotive is acquired. The current operating state includes a traction state, a coasting state, and a braking state. The braking state includes an electric braking state.

[0044] In operation S202 , when the current operating state of the diesel locomotive is an electric braking state, a first trend graph of changes in engine torque versus engine speed of the diesel locomotive is obtained.

[0045] In operation S203 , a target rotation speed is determined based on the first trend graph.

[0046] In operation S204, the engine speed of the diesel locomotive is adjusted to a target speed.

[0047] According to an embodiment of the present disclosure, when a diesel locomotive switches from an electric braking state to an idling state, the energy originally consumed or fed back by the electric braking system will suddenly be transferred to the power system, causing large fluctuations in the engine speed and affecting the engine service life.

[0048] Figure 3 The schematic diagram of the operating state of a diesel locomotive according to an embodiment of the present disclosure is schematically shown, wherein the R1 diesel engine and the R2 diesel engine are two engines of the same diesel locomotive.

[0049] like Figure 3 As shown, when the running time of the diesel locomotive is 12:03:15, the train is in the state of switching from electric braking to coasting. At this time, the train speed decreases, the grid voltage decreases, the actual speed of the R1 diesel engine and the R2 diesel engine decreases, and the diesel engine load rate suddenly increases.

[0050] In order to reduce the impact of sudden load changes on the engine, the engine speed can be adjusted when the diesel locomotive switches from electric braking to coasting to improve the engine's load resistance, thereby reducing the impact of sudden load changes on the engine's service life.

[0051] According to an embodiment of the present disclosure, engine torque is related to the engine's load-carrying capacity. Generally, the greater the engine torque, the more responsive the engine is to changes in load, i.e., the greater the engine's load-carrying capacity. There is also a corresponding relationship between engine torque and engine speed. Therefore, to ensure that the engine has a strong load-carrying capacity under electric braking, a target engine torque can first be determined, where the target engine torque corresponds to a stronger engine load-carrying capacity; then, a target speed can be determined based on the target engine torque. As a result, when the engine is operating at the target speed, the engine has a strong load-carrying capacity, which can effectively reduce the impact of sudden load changes on the engine's service life.

[0052] According to an embodiment of the present disclosure, specifically, in operation S201, a diesel locomotive can have multiple operating states, including, for example, a traction state, a coasting state, and a braking state. The braking state can include an electric braking state. The electric braking state refers to the state in which the diesel locomotive is currently braking using the electric braking system. Typically, the train uses the electric braking system for braking when the train speed is above 10 km / h.

[0053] According to an embodiment of the present disclosure, in operations S202 and S203, the target speed can be determined based on a pre-constructed first trend graph showing changes in engine torque versus engine speed for a diesel locomotive. For example, since the engine's load capacity is strongest when the engine torque is at its maximum, the engine speed corresponding to the maximum engine torque can be read from the first trend graph and used as the target speed.

[0054] According to an embodiment of the present disclosure, in operation S204, after determining the target speed, the engine speed of the diesel locomotive may be adjusted to the target speed, thereby improving the load resistance of the engine in the electric braking state.

[0055] According to an embodiment of the present disclosure, a pre-built engine characteristic curve diagram may be obtained. The engine characteristic curve diagram may include, for example, a first trend diagram of engine torque changing with engine speed, and may also include a schematic diagram of engine output power changing with engine speed.

[0056] Figure 4 A first trend diagram showing changes in engine torque with engine speed according to an embodiment of the present disclosure is schematically shown. Figure 5 The diagram schematically shows the variation of engine output power with engine speed according to the present disclosure.

[0057] like Figure 4 As shown in the figure, for a diesel engine, the speed at which its torque reaches its maximum is 1300 rpm. At this time, the diesel engine has the strongest load resistance, so the target speed can be determined to be 1300 rpm. When the handle of the diesel locomotive is in the braking state, the speed of the diesel engine can be increased to 1300 rpm, thereby reducing the impact of the sudden load on the diesel engine speed. Figure 5 As shown, for this diesel engine, when the speed is 1300rpm, the output power is 600KW.

[0058] It should be noted that the target speeds of diesel engines of different models may be different. The description of the target speed value in the embodiment of the present disclosure is only exemplary and does not limit the target speed value in any form.

[0059] Existing control methods for diesel locomotives typically operate the engine at idle speed when the locomotive switches to electric braking. However, engines installed in diesel multiple unit (DMU) trains often have low idle speeds and poor load-carrying capabilities. Specifically, when a train transitions from electric braking to coasting, energy previously consumed or fed back by the electric braking system is suddenly transferred to the powertrain, causing significant fluctuations in engine speed, thus impacting engine life.

[0060] According to an embodiment of the present disclosure, when a diesel locomotive is currently operating in an electric braking state, the engine speed is adjusted to a target speed. The target speed corresponds to a speed at which the engine has a strong load-carrying capacity. This allows the engine speed to fluctuate within a reasonable range, ensuring a greater load-carrying capacity, effectively reducing the impact of sudden load changes on the engine's service life, and improving engine operational reliability. Furthermore, determining the target speed based on the first trend graph allows for a simple and accurate determination of the corresponding relationship between engine torque and engine speed. Once the target engine torque is determined, the target speed can be accurately determined.

[0061] According to an embodiment of the present disclosure, determining the target rotation speed based on the first trend graph may include operations 11 to 13 .

[0062] In operation 11 , a predetermined threshold range of engine torque is determined.

[0063] In operation 12 , an engine speed range corresponding to a predetermined threshold range is read from a first trend map.

[0064] In operation 13 , a target speed is determined based on the engine speed range.

[0065] According to an embodiment of the present disclosure, based on the actual operating requirements of a diesel locomotive, a predetermined threshold range of engine torque can be first determined. Within this predetermined threshold range, the engine's load-carrying capacity is relatively strong. The engine speed range corresponding to the predetermined threshold range is then read from the first trend graph.

[0066] According to an embodiment of the present disclosure, determining the target rotation speed based on the first trend graph may further include operations 21 and 22 .

[0067] In operation 21 , an engine speed corresponding to when the engine torque is maximum is determined based on the first trend map.

[0068] In operation 22 , the engine speed corresponding to when the engine torque is maximum is set as the target speed.

[0069] According to the embodiments of the present disclosure, since an engine's load capacity is typically greatest when its torque is at its maximum, the engine speed corresponding to the maximum torque can be directly read from the first trend graph and used as the target speed. Thus, adjusting the engine speed of the diesel locomotive to the target speed maximizes the engine's load capacity.

[0070] According to an embodiment of the present disclosure, based on the pre-constructed first trend graph, the engine speed corresponding to the maximum engine torque can be accurately read, thereby improving the accuracy of determining the target speed.

[0071] According to an embodiment of the present disclosure, the control method of the above-mentioned diesel locomotive further includes: when the current operating state of the diesel locomotive is a coasting state and the duration of the current operating state exceeds a predetermined time threshold, adjusting the engine speed of the diesel locomotive to an idle speed.

[0072] According to an embodiment of the present disclosure, Figure 3 It can be seen that for a period of time after the diesel locomotive switched to the idling state (running time was 12:03:15~12:03:18), the engine load rate was still at a high level; as time continued to increase, the engine load rate gradually reached a lower level.

[0073] According to an embodiment of the present disclosure, within a predetermined time threshold, the engine load rate is still at a relatively high level, and the engine still needs to maintain a relatively high load resistance, so the engine speed is still the target speed; when the duration of the idling state exceeds the predetermined time threshold, the engine load rate reaches a relatively low level, and therefore there is no need to maintain a relatively high load resistance, and the engine speed of the diesel locomotive can be adjusted to the idle speed.

[0074] According to an embodiment of the present disclosure, the engine speed of the diesel locomotive is adjusted to the idle speed only when the duration of the coasting state exceeds a predetermined time threshold. By deeply exploring the changing pattern of the engine load rate, the impact of the energy consumed or fed back by the electric braking system on the engine service life when it is suddenly transferred to the power system can be further reduced.

[0075] According to an embodiment of the present disclosure, specifically, a second trend graph of changes in the engine load rate of the diesel locomotive with the running time can be obtained; and based on the second trend graph, a predetermined time threshold is determined.

[0076] For example, after obtaining a second trend graph showing the engine load factor of a diesel locomotive as a function of operating time, it can be determined based on the second trend graph that the engine load factor remained high between 12:03:15 and 12:03:18. After 12:03:18, the engine load factor reached a low level. Therefore, the predetermined time threshold can be determined to be 3 seconds.

[0077] According to an embodiment of the present disclosure, the engine load rate can measure the working intensity of the engine within a specific time, which reflects the ratio between the actual output power and the maximum output power of the engine.

[0078] According to an embodiment of the present disclosure, a second trend graph can be pre-constructed to intuitively show how the engine load rate changes with the running time of the diesel locomotive, thereby accurately determining the predetermined time threshold corresponding to when the engine load rate remains at a high level.

[0079] According to an embodiment of the present disclosure, the control method of the above-mentioned diesel locomotive also includes: when the current operating state of the diesel locomotive is the traction state, determining the target traction level corresponding to the current operating state; and adjusting the engine speed of the diesel locomotive to the speed corresponding to the target traction level.

[0080] According to an embodiment of the present disclosure, after the diesel locomotive returns to the traction state, the engine speed of the diesel locomotive is adjusted to the speed corresponding to the target traction level so that the diesel locomotive can operate normally.

[0081] Figure 6 A block diagram schematically shows a control device for a diesel locomotive according to an embodiment of the present disclosure.

[0082] like Figure 6 As shown, the control device 600 of the diesel locomotive in this embodiment includes a first acquisition module 610 , a second acquisition module 620 , a first determination module 630 , and a first adjustment module 640 .

[0089] According to an embodiment of the present disclosure, the first determining module includes a third determining submodule.

[0090] The third determining submodule is configured to determine, based on the first trend graph, an engine speed corresponding to when the engine torque is maximum; and use the engine speed corresponding to when the engine torque is maximum as a target speed.

[0091] According to an embodiment of the present disclosure, the control device of the diesel locomotive further includes a second adjustment module.

[0092] The second adjustment module is used to adjust the engine speed of the diesel locomotive to the idle speed when the current running state of the diesel locomotive is the coasting state and the duration of the current running state exceeds a predetermined time threshold.

[0094] The acquisition submodule is used to obtain a second trend graph of the engine load rate of the diesel locomotive changing with the running time; the fourth determination submodule is used to determine a predetermined time threshold based on the second trend graph.

[0095] According to an embodiment of the present disclosure, the control device of the diesel locomotive further includes a second determination module and a third adjustment module.
