Automobile and idling start-stop controlling method and device thereof

Abstract

The invention discloses an automobile and an idling start-stop controlling method and device thereof. The automobile comprises an idling start-stop switch. The idling start-stop controlling method comprises the following steps that user instructions are received through the idling start-stop switch; engine shutdown request instructions are generated when the condition that the idling start-stop switch is triggered in a first mode is judged according to the user instructions; and when an engine controller receives the engine shutdown request instructions, if the engine controller judges that the automobile meets the preset idling start-stop condition, an engine is controlled to be shut down. Therefore, according to the idling start-stop controlling method, a driver needs to determine whether the engine needs to be shut down or not according to driving conditions so that the fuel saving efficiency of idling start-stop can be improved, the loss of a storage battery and an engine starting system is reduced, and increasing of hardware cost is not required.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile idle start-stop control method, an automobile idle start-stop control device and an automobile. Background technique [0002] Due to the stricter restrictions on fuel consumption and emission indicators, more and more idling start-stop functions are configured in automobiles. Also, the idle start-stop function is turned on by default every time the engine is fired. [0003] However, the logic of idling start and stop of ordinary cars is not smart enough, which leads to uncertainty about the intervention time of automatic engine start and stop. It often happens that the engine will be turned off immediately after a short stop, and the engine will start immediately after the driver releases the brakes. In a slightly congested road section, the engine will start and stop frequently, which will not only reduce the starting speed of the car, but also cause serious d...

[0003] However, the logic of idling start and stop of ordinary cars is not smart enough, which leads to uncertainty in the intervention time of automatic engine start and stop

It often happens that the engine will be turned off immediately after a short stop, and the engine will start immediately after the driver releases the brakes. In a slightly congested road section, the engine will start and stop frequently, which will not only reduce the starting speed of the car, but also cause serious damage to the engine starting system and battery. big damage

After a long time of parking, the engine may not automatically stop or start automatically, and the idling start and stop function may fail, which will bring great inconvenience to the user.
