Abstract

A method and a device for controlling an engine to shut down, and an electronic device and a storage medium are provided. The method includes: obtaining current state information and operating parameter information of an engine, the current state information comprising a starting state, and the operating parameter information comprising rotating speed information, starting duration information, cooling liquid temperature information and torque information of the engine; and if the current state information is the starting state, and the rotating speed information, the starting duration information, the cooling liquid temperature information, and the torque information satisfy a first preset shutdown condition corresponding to the starting state, controlling the engine to be in a shutdown state.

First claim

1 . A method for controlling engine to shut down, comprising:
acquiring current state information and operation parameter information of an engine, wherein the current state information comprises a starting state, and the operation parameter information comprises revolution speed information, start duration information, coolant temperature information and torque information of the engine; and controlling the engine to be in a shutdown state if the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet a first preset stop condition corresponding to the starting state.

2 . The method according to claim 1 , wherein the current state information further comprises an operating state;
the method further comprises: controlling the engine to be in the shutdown state if the current state information is the operating state, and the revolution speed information meets a second preset stop condition corresponding to the operating state.

3 . The method according to claim 1 , wherein the current state information further comprises the shutdown state, and the operation parameter information further comprises engine-restart number information, stop duration information, vehicle speed information and safety equipment working information;
the method further comprises: controlling the engine to be in the shutdown state if the current state is the shutdown state, and the restart number information, the stop duration information, the vehicle speed information and the safety equipment working information meet a third preset stop condition corresponding to the shutdown state.

4 . The method according to claim 1 , wherein the starting state comprises states corresponding to starting based on a plurality of starting modes, which comprise a 12V starting mode, a first motor starting mode and a clutch starting mode;
the first preset stop condition comprises a first sub-condition corresponding to the 12V starting mode, a second sub-condition corresponding to the first motor starting mode and a third sub-condition corresponding to the clutch starting mode.

5 . The method according to claim 4 , wherein controlling the engine to be in the shutdown state if the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the first preset stop condition corresponding to the starting state comprises:
controlling the engine to be in the shutdown state if the starting state is a state corresponding to starting based on the 12V starting mode, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the first sub-condition.

6 . The method according to claim 4 , wherein controlling the engine to be in the shutdown state if the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the first preset stop condition corresponding to the starting state comprises:
controlling the engine to be in the shutdown state if the starting state is a state corresponding to starting based on the first motor starting mode, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the second sub-condition.

7 . The method according to claim 3 , wherein controlling the engine to be in the shutdown state if the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the first preset stop condition corresponding to the starting state comprises:
controlling the engine to be in the shutdown state if the starting state is a state corresponding to starting based on the clutch starting mode, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet the third sub-condition.

8 . A device for controlling engine to shut down, comprising:
an acquisition module, configured to acquire current state information and operation parameter information of an engine, wherein the current state information comprises a starting state, and the operation parameter information comprises revolution speed information, start duration information, coolant temperature information and torque information of the engine; and a control module, configured to control the engine to be in a shutdown state if the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet a first preset stop condition corresponding to the starting state.

9 . An electronic equipment comprising a processor and a memory, wherein at least one instruction, at least one program, a code set or an instruction set is stored in the memory, and the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to implement the method for controlling engine to shut down according to claim 1 .

10 . A computer-readable storage medium, wherein at least one instruction, at least one program, a code set or an instruction set is stored in the storage medium, and the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by a processor to implement the method for controlling engine to shut down according to claim 1 .

11 . The device for controlling engine to shut down according to claim 8 , wherein the current state information further comprises an operating state; and the control module is configured to control the engine to be in the shutdown state if the current state information is the operating state and the revolution speed information meets a second preset stop condition corresponding to the operating state.

12 . The device for controlling engine to shut down according to claim 8 , wherein the current state information further comprises the shutdown state, and the operation parameter information further comprises engine-restart number information, stop duration information, vehicle speed information and safety equipment working information; and
the control module is configured to control the engine to be in the shutdown state if the current state is the shutdown state, and the restart number information, the stop duration information, the vehicle speed information and the safety equipment working information meet a third preset stop condition corresponding to the shutdown state.

13 . The device for controlling engine to shut down according to claim 8 , wherein the starting state comprises states corresponding to starting based on a plurality of starting modes, which comprise a 12V starting mode, a first motor starting mode and a clutch starting mode;
the first preset stop condition comprises a first sub-condition corresponding to the 12V starting mode, a second sub-condition corresponding to the first motor starting mode and a third sub-condition corresponding to the clutch starting mode.

14 . The device for controlling engine to shut down according to claim 13 , wherein the control module is configured to control the engine to be in the shutdown state if the starting state is the state corresponding to starting based on the 12V starting mode, and the revoluti
