Detailed Description
The embodiment of the application provides a control method, an engine controller and a device for an idle speed switch of an engine, which are used for stabilizing the alternating current frequency output by the engine.
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, an embodiment of the present application provides a control method of an idle switch of an engine, including:
101. the engine controller receives a starting signal of the idle speed switch;
work vehicles typically are externally connected with work equipment, and common work vehicles include: the sprinkler, crane, etc., are not particularly limited herein. In the watering lorry, idle speed switch is arranged in controlling the start-stop state of watering lorry squirt, when idle speed switch starts, then the squirt needs to carry out watering work at this moment, consequently the vehicle needs to open the squirt for the engine supplies energy to the water pump, under the circumstances of watering lorry, idle speed switch's closing needs to pass through external setting. In a crane, an idle switch is generally used for controlling the extension of a crane supporting leg, and when the extension of the supporting leg is completed, a signal of ending the work is fed back to an engine controller.
102. The engine controller obtains a preset rotating speed value of the idle speed switch according to the starting signal;
the preset rotating speed value of the idle speed switch can be adjusted according to external equipment of the vehicle in actual conditions, so that the alternating current voltage output by the engine at the preset rotating speed is enough to supply corresponding working equipment to work.
103. The engine controller sets the rotating speed of the engine according to the preset rotating speed value;
after the engine controller acquires the preset rotating speed value, the rotating speed value of the engine is controlled to be in a state of the preset rotating speed value, and in practical situations, the rotating speed required by the engine for supplying energy to external equipment is higher than that required by the engine for driving the vehicle only under load, so that the condition that the function of the external equipment cannot be met exists when the rotating speed of the engine is controlled only by virtue of an accelerator, and after the rotating speed value of the engine is preset by the engine controller, the engine can reach the rotating speed and keep constant speed, so that the working vehicle is in a stable working state.
104. The engine controller monitors the working state of the external equipment controlled by the idle speed switch;
in practical situations, such as the supporting leg of a crane, there is a fixed working period, and the power supply is not required to be kept after the working is completed, in which case the engine controller needs to monitor the working state of the external equipment controlled by the idle speed switch.
105. And when the working state is finished, the engine controller closes the idle speed switch and resets the rotating speed of the engine to an initial idle state.
The working state acquisition mode of the external equipment can be fed back to the engine after the work of the external equipment is completed by the engine controller, and the engine controller can monitor that the external equipment stops working. When the engine controller determines that the working state of the external equipment is finished, the engine controller can close the idle speed switch, so that the engine is reset to a state before the idle speed switch is opened, and the aim of avoiding excessive energy consumption is fulfilled.
According to the technical scheme, the engine controller controls the rotating speed of the engine by controlling the idle speed switch, so that the rotating speed of the engine can be stabilized when the engine supplies energy to external equipment, and the purpose of stabilizing the power of alternating current output by the engine is achieved.
Referring to fig. 2, another embodiment of a control method of an idle switch of an engine is provided in an embodiment of the present application, including:
201. the engine controller receives a starting signal of the idle speed switch;
step 201 in this embodiment is similar to step 101 in the previous embodiment, and detailed description thereof is omitted here.
202. The engine controller judges whether the idle speed switch is bound with a remote throttle or not;
the remote throttle is a throttle control mode that allows the rotational speed of the engine to rise to a preset rotational speed in a fixed curve, and when the remote throttle is bound to the idle switch, the idle switch must be used in a state where the remote throttle is turned on, and when the remote throttle is bound to the idle switch, step 203 is executed.
203. If so, the engine controller judges whether the remote throttle is in an open state;
if the idle switch is bound to the remote throttle, the idle switch must be started when the remote throttle is started, so the engine controller needs to determine the start state of the remote throttle, if the remote switch is in the on state, the step 204 is executed, and if the remote switch is in the off state, the step 207 is executed.
204. If the engine is in an on state, the engine controller judges whether the priority of the idle speed switch is higher than the priority of the remote throttle;
when the remote throttle is in the on state, it indicates that the idle switch can be started, and at this time, the engine controller needs to determine the priorities of the remote throttle and the idle switch, and the control logic of the two follows the principle of priority execution, when the priority of the idle switch is higher than the priority of the remote throttle, step 205 is executed, and when the priority of the idle switch is lower than the priority of the remote throttle, step 206 is executed.
205. If yes, the engine controller directly starts a control strategy corresponding to the idle speed switch.
When the priority of the idle switch is higher than that of the remote throttle, the engine controller directly executes a control strategy of the idle switch, namely, directly increases the rotating speed of the engine to a preset rotating speed value of the remote throttle.
206. If not, the engine controller preferentially increases the rotating speed of the engine through the remote accelerator until the rotating speed of the engine reaches the preset rotating speed value of the idle speed switch.
When the priority of the idle speed switch is lower than that of the remote throttle, the engine controller keeps executing the control strategy of the current remote throttle, namely, the rotating speed of the engine is increased according to a preset curve, and the engine can not start the control strategy of the idle speed switch until the engine controller determines that the rotating speed of the engine reaches the preset rotating speed value of the idle speed switch.
207. And if the engine is not in the on state, the engine controller controls the engine to keep the current running state.
If the remote throttle is not in the on state at this time, the start signal of the idle speed switch is used as an invalid request by the engine controller, so that the engine controller can control the engine to keep the current running state.
208. The engine controller obtains a preset rotating speed value of the idle speed switch according to the starting signal;
step 208 in this embodiment is similar to step 102 in the previous embodiment, and detailed description thereof is omitted here.
209. The engine controller acquires a rotational speed correction logic, wherein the rotational speed correction logic is used for correcting the rotational speed of an engine when the working environment of the engine is in an abnormal state;
abnormal conditions of the working environment include, but are not limited to, conditions of low temperature, high temperature and low pressure, and are not limited thereto. When the working environment is abnormal, the operation data of the engine can be influenced, so that the preset rotation speed value of the idle speed switch needs to be adjusted according to the correction logic in order to ensure that the engine can stabilize the voltage output by external equipment.
210. And the engine controller corrects the preset rotating speed value according to the rotating speed correction logic.
When the engine controller determines that the current running state of the engine is not in a normal state through the vehicle-mounted air pressure sensor or the temperature sensor, the engine controller acquires correction logic corresponding to an abnormal environment before setting the engine speed, adjusts the speed according to the correction logic, and the embodiment form of the correction logic in the engine controller is a corresponding relation comparison table, so that the engine controller can find a corresponding relation according to the current acquired temperature value or air pressure value on the corresponding relation comparison table to correct the preset speed value.
211. The engine controller sets the rotating speed of the engine according to the preset rotating speed value;
212. the engine controller monitors the working state of the external equipment controlled by the idle speed switch;
213. and when the working state is finished, the engine controller closes the idle speed switch and resets the rotating speed of the engine to an initial idle state.
Steps 211 to 213 in this embodiment are similar to steps 101 to 105 in the previous embodiment, and detailed descriptions thereof are omitted herein.
In the embodiment of the application, the idle switch has a state associated with the remote throttle, when the idle switch is associated with the remote throttle, the engine controller adjusts the control strategy according to the priority of the idle switch and the remote throttle, and the engine controller has a rotation speed correction logic, that is, the rotation speed of the engine is affected by air pressure in an abnormal state to reduce the output power, and the rotation speed correction logic can correct the rotation speed to achieve the purpose of stabilizing the output power of the engine in the abnormal state.
