Engine idling self-learning method, vehicle and computer-readable storage medium

Abstract

Embodiments of the present disclosure relate to an engine idling self-learning method, a vehicle, and a computer-readable storage medium, wherein the engine idling self-learning method is applied to an extended-range electric vehicle, including: when the engine is running, if received An engine shutdown instruction, judging whether the engine is normally shut down; in the case of the normal shutdown of the engine, controlling the engine to enter the idle speed state to perform idle speed self-learning; Described engine cuts off oil and shuts down. The technical solution provided by the invention solves the problem that the existing vehicle enters the idling self-learning working condition without considering the impact of engine shutdown on the whole vehicle, resulting in poor NVH performance of the whole vehicle.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of communication technologies, and in particular, to an engine idle speed self-learning method, a vehicle, and a computer-readable storage medium. Background technique [0002] During the engine control process of the vehicle, the engine controller needs to have an idle speed self-learning process. However, for extended-range electric vehicles, since the engine does not generate electricity during the pure idling process, the power of the vehicle is affected. At the same time, from the perspective of the vehicle, in order to ensure good NVH (Noise, Vibration, Harshness, Noise, Vibration and Acoustic Vibration) Roughness) performance, the existing range extension is that most of the electric vehicles do not consider the idle speed self-learning of the engine. In addition, in the existing engine idle speed self-learning condition, as long as the engine is stopped, the engine will enter the idle s...
