Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that references in the specification of the present application to the terms "comprises" and "comprising," and variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
At present, the operation conditions of the engine for the agricultural machinery are mostly on the speed regulation section with external characteristics, namely, when the vehicle works, the operation is finished by adopting a mode of operating an accelerator. However, this approach can result in higher fuel consumption of the vehicle.
In the related art, a multi-power fuel-saving switch mode is adopted, and different external characteristic curves are set through different gears. This approach generally requires a user to manually select a plurality of range switches in the multi-power economizer to set the vehicle to operate at a corresponding power, which may result in an under-powered malfunction of the vehicle if the user forgets to switch the range switches when the vehicle is in a high-load operating state, and still requires the user to operate the throttle. Therefore, the operation of the multi-power fuel-saving switch is complicated, and the fuel consumption of the vehicle cannot be reduced well.
In order to reduce the oil consumption of a vehicle, enable the operation of a user to be simple and avoid the power shortage fault of the vehicle, the application provides the engine economic mode control method, the method can control the vehicle to enter the economic mode after determining that the user selects to enter the economic mode through a control switch corresponding to the economic mode, keep the engine running at a target rotating speed constantly, and control the vehicle to exit the economic mode after monitoring that the rotating speed of the engine exceeds a set rotating speed threshold value by stepping on an accelerator of the user and continuously setting the time length.
The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
The embodiment of the application provides an engine economy mode control method, as shown in FIG. 1, comprising the following steps:
and S101, after determining that the user selects to enter the economy mode through the control switch corresponding to the economy mode, controlling the vehicle to enter the economy mode.
Wherein, when the vehicle enters the economy mode, the rotation speed of the engine of the vehicle is changed from the current rotation speed to the target rotation speed.
In step S101, a control switch corresponding to the economy mode may be installed in a cab of the vehicle, and when the vehicle is in the power mode, that is, when the vehicle is running normally, if a user closes the control switch, the vehicle may be controlled to switch from the power mode to the economy mode, and when the vehicle enters the economy mode, the rotation speed of the engine is shifted from the current rotation speed to the target rotation speed.
Step S102, keeping the engine running at the target rotating speed constant.
After controlling the vehicle to enter the economy mode, the engine may be operated with the target rotational speed kept constant.
And step S103, controlling the vehicle to exit the economic mode after monitoring that the rotation speed of the engine exceeds a set rotation speed threshold value through stepping on the accelerator by the user and continuing for a set time length.
After the vehicle enters the economy mode, if the user steps on the accelerator to enable the rotating speed of the engine to exceed a set rotating speed threshold value, namely the rotating speed of the engine exceeds a target rotating speed, the difference between the rotating speed and the target rotating speed meets the set threshold value, and after the set duration is continued, the vehicle can be controlled to exit the economy mode. After the vehicle exits the economy mode, the vehicle may be controlled to enter the power mode.
Before the control switch corresponding to the economy mode determines that the user selects to enter the economy mode, the engine is determined to run at the idle speed or higher, and the engine state is normal. The idle speed is the speed of the engine in the zero-accelerator operation state.
In one embodiment, after the vehicle is controlled to enter the economy mode, the vehicle can be controlled to exit the economy mode after the user selects to exit the economy mode through a control switch corresponding to the economy mode. Or controlling the vehicle to exit the economy mode after the engine is monitored to stop being electrified, or controlling the vehicle to exit the economy mode when the engine is monitored to be abnormal in state. And, after controlling the vehicle to exit the economy mode, the vehicle may be controlled to enter the power mode. After the vehicle enters the power mode, the rotating speed of the engine is controlled by the throttle operation of the vehicle by a user.
In another embodiment, after controlling the vehicle to enter the economy mode, when it is monitored that the user brakes the vehicle, the vehicle is controlled to exit the economy mode, and the rotational speed of the engine is controlled to transition from the target rotational speed to the idle rotational speed. The idle speed is the speed of the engine in the zero-accelerator operation state.
Generally, vehicles such as agricultural machinery have two throttles, namely a hand throttle and a foot throttle, wherein the foot throttle is mainly used for vehicle transition, the hand throttle is mainly used for normal operation of the vehicles, and the main purpose of the hand throttle is to solve the problem that the opening degree of the foot throttle is unstable in the operation process. The vehicle running mode that the hand throttle is pulled to the bottom to ensure the constant rotating speed of the engine is a power mode. In the power mode, the user is required to operate the throttle to adjust the speed of the vehicle and the engine speed at any time. A control switch corresponding to an economy mode can be installed in a cab of a vehicle, and when a user closes the control switch, the engine can run at a constant rotating speed without throttle operation.
FIG. 2 is a control logic diagram for the engine in both power and economy modes. As shown in fig. 2, the engine is operated in the power mode, the rotation speed of the engine is controlled by the throttle ratio of the hand throttle to the foot throttle, that is, the engine is operated by the rotation speed corresponding to the larger throttle of the hand throttle and the foot throttle. The engine is operated in the economy mode with a constant speed to control the speed of the engine, i.e. the engine is operated at a constant speed.
In some embodiments, the engine economy mode control method presented herein may also be implemented in accordance with the process illustrated in FIG. 3. As shown in fig. 3, the following steps may be included:
step S301, the rotation speed of the engine is determined to be greater than or equal to the idling rotation speed, and the engine state is normal.
And determining that the engine works normally, namely the rotating speed of the engine is greater than or equal to the idle speed, and the engine state is normal.
And step S302, after the control switch corresponding to the economy mode is monitored to be closed, controlling the vehicle to enter the economy mode.
When it is monitored that the user closes the control switch corresponding to the economy mode, the vehicle can be controlled to enter the economy mode.
In step S303, when the vehicle enters the economy mode, the rotation speed of the engine is changed from the current rotation speed to the target rotation speed.
When the vehicle enters the economy mode, the rotation speed of the engine needs to be shifted from the current rotation speed to the target rotation speed. The engine ECU may record the current rotational speed of the engine and calculate a path from the current rotational speed to the target rotational speed when the control switch corresponding to the economy mode is closed, so as to ensure that the rotational speed of the engine changes smoothly.
Step S304, the engine is kept running at the target rotating speed.
The vehicle may maintain the engine operating at the target speed constant after entering the economy mode. For example, the target speed may be 1800 rpm.
When the engine runs at the target rotating speed constantly, the engine ECU can automatically increase and decrease the oil quantity according to the external load change so as to maintain the rotating speed of the engine to be stable.
And step S305, after monitoring that the rotation speed of the engine exceeds a set rotation speed threshold value by stepping on the accelerator by a user and continuing for a set time, controlling the vehicle to exit the economic mode.
And after the situation that the rotating speed of the engine exceeds a set rotating speed threshold value by stepping on the accelerator by a user and the set time duration is continued is monitored, the vehicle can be controlled to exit the economic mode. For example, when the accelerator is stepped on so that the engine speed exceeds the target speed +100rpm, and exceeds 2s, the vehicle may be controlled to exit the economy mode.
And step S306, after the control switch corresponding to the economy mode is monitored to be turned on, controlling the vehicle to exit the economy mode.
Or after the control switch corresponding to the economy mode is monitored to be turned on, the vehicle can be controlled to exit the economy mode.
And step S307, controlling the vehicle to exit the economy mode after the engine is monitored to stop electrifying.
Alternatively, the vehicle may be controlled to exit the economy mode upon detection of engine de-energization, i.e., detection of power-down of the engine T15.
And step S308, controlling the vehicle to exit the economy mode when the condition of the engine is monitored to be abnormal.
Alternatively, the vehicle may be controlled to exit the economy mode when an engine condition anomaly is monitored.
In step S309, the vehicle is controlled to enter the power mode.
After the vehicle exits the economy mode, the vehicle may be controlled to enter the power mode. After the vehicle enters the power mode, the rotation speed of the engine needs to be controlled by the throttle operation of the vehicle by the user.
And S310, when the user brakes the vehicle, controlling the vehicle to exit the economic mode and controlling the rotating speed of the engine to be converted from the target rotating speed to the idle rotating speed.
The vehicle may also be controlled to exit the economy mode if it is monitored that the user brakes the vehicle after the vehicle is entering the economy mode. After the vehicle exits the economy mode, the rotational speed of the engine may be controlled to transition from the target rotational speed to the idle rotational speed.
Road spectrum analysis shows that when the engine runs in an economic mode, the vehicle can save 19.2 percent of oil compared with when the engine runs in a power mode, and the oil consumption of the vehicle is greatly reduced.
According to the engine economy mode control method provided by the embodiment of the application, a control switch corresponding to an economy mode can be installed in a cab of a vehicle, the running mode of the engine can be switched through switch switching, namely after the control switch is closed, the running mode of the engine can be switched from a power mode to the economy mode, the rotating speed of the engine can be switched to a target rotating speed at the moment, and the engine keeps the target rotating speed to run constantly; when the control switch is turned on, or the user steps on the accelerator to enable the rotating speed of the engine to exceed a set rotating speed threshold value for a set time, or the state of the engine is abnormal, the running mode of the engine can be switched from the economy mode to the power mode.
The rotating speed of the engine can be fixed on a target rotating speed to operate constantly, so that the fuel consumption of the vehicle can be reduced. The method only needs to add one control switch, does not need to greatly change the structure of the vehicle, has simple structure, does not need a user to operate an accelerator after the vehicle enters an economic mode, can use a constant rotating speed function, ensures that the rotating speed of the engine is constant, not only has simple operation, but also can reduce the oil consumption on the premise of ensuring that the vehicle can normally work. In addition, when the vehicle carries out heavy-load operation, the mode that can improve the rotational speed through trampling the throttle makes the vehicle exit economic mode and enter power mode to can in time improve the dynamic nature of vehicle, guarantee the normal work of vehicle, avoid the vehicle to appear the power shortage trouble.
