Abstract

The invention discloses an engine starting control method and device, electronic equipment and a storage medium, and belongs to the technical field of vehicle control. The method comprises the steps of: according to the current vehicle speed, the stroke of the accelerator pedal and the current driving mode, determining the required torque; determining the maximum available driving torque of the motor according to the peak torque of the motor at the current rotating speed and the reserved torque of the motor; and according to the required torque and the maximum available driving torque, determining whether an engine is controlled to start or not. According to the technical scheme, under the working conditions of different driving modes, engine starting is effectively controlled, and the driving experience of a user is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, and in particular to an engine start control method, device, electronic equipment, and storage medium. Background technique [0002] Compared with traditional vehicles, due to the addition of motors and power batteries, hybrid vehicles do not need traditional starters during the engine start and stop process, and use batteries and motors to achieve more superior start and stop performance. [0003] In the prior art, in the process of starting and stopping the engine, how to effectively control the starting of the engine under different driving modes has not been considered, and improvement is urgently needed. Contents of the invention [0004] The present invention provides an engine start control method, device, electronic equipment and storage medium, so as to improve user driving experience. [0005] In a first aspect, an embodiment of the present invention pro...
