Embodiment 2

[0126] Embodiment 2 is substantially the same as Embodiment 1, the difference is that there are other steps between steps S400 and S500, Figure 7 It is a partial flow diagram of the gasoline engine throttle valve dew cleaning control method according to the second embodiment of the present application. Such as Figure 7 As shown, after step S400, the following steps are included:

[0127] S601. Obtain battery voltage V 1 .

[0128] S602. Determine battery voltage V 1 Is it greater than the rated voltage V 0 .

[0129] If so, the battery voltage V 1 Greater than the rated voltage value V 0 , then go to step S500 after step S602.

[0130] If not, the battery voltage V 1 Less than the rated voltage value V 0 , then go to step S603 after step S602, and issue a low voltage prompt.

[0131] Specifically, the battery voltage of a car is generally around 12V, and it will increase to 13V-14V after the vehicle is started. In the embodiment of this application, the calibratio...

Embodiment 3

[0135] Embodiment 3 is substantially the same as Embodiment 1, the difference is that there are other steps between steps S400 and S500, Figure 8 It is a partial flow chart of the gasoline engine throttle dew cleaning control method according to Embodiment 3 of the present application. Such as Figure 8 As shown, after step S400, the following steps are also included:

[0136] S701. Detect whether a fault signal is received.

[0137] If not, continue to step S202.

[0138] If yes, go to step S702 and issue a fault prompt.

[0139] Specifically, after step S400, go to step S701 to detect whether a fault signal is received, and if no fault signal is received, go to step S500. If a battery failure signal is received, for example, a battery failure prompt is issued.

[0140] Specifically, fault signals include the following:

[0141] 1. Battery fault signal, for example, if the battery fault light is on, once the car’s battery signal light is still on after the car starts, it...

Embodiment 4

[0147] This embodiment provides a gasoline engine throttle valve dew cleaning control device, such as Figure 9 , the control device includes an ambient temperature and humidity acquisition module 10 , a cleaning condition judgment module 20 , an engine temperature acquisition module 30 , an execution time determination module 40 and a cleaning action control module 50 . Specifically, the ambient temperature and humidity acquisition module 10 is used to acquire the 0 Ambient temperature H 0 and ambient humidity Hu 0 . Cleaning condition judging module 20 is used for according to ambient temperature H 0 and ambient humidity Hu 0 Determine whether the cleaning conditions are met. The engine temperature acquisition module 30 is used to acquire the 0 The initial temperature T 0 . The execution time determination module 40 is used to determine according to the flameout time t 0 , initial temperature T 0 and ambient temperature H 0 Make sure the engine drops to the preset...

Abstract

The invention belongs to the technical field of throttle valve control, and discloses a gasoline engine throttle valve dew cleaning control method, device and equipment and a storage medium. The method comprises the following steps: collecting the environment temperature and the environment humidity of an engine at the flameout moment; judging whether cleaning conditions are met or not according to the environment temperature and the environment humidity; if the cleaning condition is met, collecting the initial temperature of the engine at the flameout moment; according to the flameout time, determining the initial temperature and the environment temperature, the execution time when the engine is cooled to the preset temperature, wherein the preset temperature is not smaller than 0 DEG C; and controlling the throttle valve to execute the cleaning action at the execution moment. According to the control method, the cleaning program can be executed when the water temperature of the engine is reduced to the preset temperature, then dew cleaning is carried out before freezing, so that the freezing probability of the throttle valve is reduced to a great extent, meanwhile, the duty ratio output of the throttle valve in the ice breaking process is greatly reduced, and the service life of the throttle valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of throttle control, in particular to a gasoline engine throttle dew cleaning control method, device, equipment and storage medium. Background technique [0002] When the vehicle is in a low environment, the water vapor will condense into dew near the throttle valve. After the dew gathers, it may freeze, and in severe cases, the throttle valve plate will be stuck. When the engine is running, it may cause excessive current of the throttle motor and ablation. When the throttle valve is frozen, the throttle valve flap cannot be opened to the target position within the specified time after starting the engine, the system will report a fault code in the background, the engine will enter the torque limit state after ignition, and the throttle valve will not move when the accelerator pedal is pressed. [0003] The protection method of the engine throttle in the prior art is to achieve the purpose of breaking the i...
