Method for periodically automatically starting and stalling automotive engine

Abstract

The invention discloses a method for periodically automatically starting and stalling an automotive engine, which comprises that: 1) a periodically automatic control module is connected in parallel with a key switch in an automotive control circuit, wherein the periodically automatic control module comprises a serially connected control switch and a periodical start control integrated circuit module; 2) when an automobile stops, a setting time needed by automatically starting the automobile is input according to the next automobile using time; and 3) the periodical start control integrated circuit module judges whether an IG signal is output in the automotive key switch and whether an automotive shifting mechanism is positioned at a neutral position at any time; if the IG signal is output or the automotive shifting mechanism is not positioned at the neutral position, the control switch is directly disconnected; if the IG signal is not output or the automotive shifting mechanism is positioned at the neutral position, the periodical start control integrated circuit module judges whether the ambient temperature in the automobile is lower or higher than the set temperature when the set time is up, determines whether to start the engine according to the set temperature, and opens a corresponding air-conditioning system.

Description

technical field [0001] The present invention relates to an automobile control method, in particular, relates to a method for controlling an automobile engine to be automatically started or even automatically turned off. Background technique [0002] After the car stops for a long time, the friction pairs such as the engine cylinder and the piston ring, crankshaft, and camshaft are in a cold state, and after a long stop, the lubricating oil will have poor fluidity due to precipitation, which makes the lubrication of each friction pair when the car starts Insufficient, resulting in abnormal wear of friction pairs such as cylinder and piston ring, crankshaft, camshaft, etc. Therefore, before leaving the car, it is necessary to preheat the car engine at a timed idle speed, so that the lubricating oil remains between the various moving friction pairs, and the cylinder, piston and crankshaft are kept in a normal thermal state. Especially after a long time parked in a cold climate...

AI Technical Summary

Problems solved by technology

Especially after a long time parked in a cold climate, it is very difficult to start the car engine when using the car. After starting, the engine idling warm-up time and the time for the air conditioner to heat up the interior of the car are very long. Many drivers often give up due to time constraints. This operation directly leaves the car, which will not only cause discomfort to the driver and passengers due to the temperature inside the car, but also easily cause damage to the engine and other parts, and it is more likely to cause flameout during driving

And there is also a phenomenon that the engine is difficult to start or cannot be started due to the low temperature
