The invention discloses an engine rotating speed control method and device, a vehicle and an electronic device, and relates to the technical field of vehicles. The method comprises the steps that the target rotating speed and the first execution torque of an engine of the vehicle are determined according to the running working condition of the vehicle; second execution torque of the generator of the vehicle is determined according to the current rotating speed and the target rotating speed of the engine, and the torque difference between the first execution torque and the second execution torque is used for adjusting the rotating speed of the engine; torque of the engine and torque of the generator are adjusted based on the first execution torque and the second execution torque. The technical problems that the maximum torque of a generator in the prior art is generally larger than the maximum torque of an engine, consequently, the power of the generator is large, the power of the generator is excessive, and the generator is high in cost, large in design difficulty and not easy to achieve are solved.

    本发明公开了一种发动机转速控制方法、装置、车辆及电子装置,涉及车辆技术领域。其中,该方法包括:根据车辆的行驶工况确定车辆的发动机的目标转速和第一执行扭矩;根据发动机的当前转速和目标转速确定车辆的发电机的第二执行扭矩,其中,第一执行扭矩和第二执行扭矩之间的扭矩差用于调整发动机转速;基于第一执行扭矩和第二执行扭矩调整发动机的扭矩和发电机的扭矩。本发明解决了相关技术中的发电机的最大扭矩一般大于发动机的最大扭矩,导致发电机功率较大,发电机存在功率过剩的情况,且发电机的成本较高,设计难度较大,不易实现的技术问题。
