The invention belongs to the technical field of vehicles, and discloses an engine rotating speed control method, equipment, a storage medium and a device.When a target vehicle is in a series power generation mode and a brake pedal signal is detected, a motor recovery torque corresponding to a target motor of the target vehicle is obtained; judging whether the rotating speed of the engine needs to be compensated or not according to the motor recovery torque and the preset suspension torque, and obtaining a judgment result; the target engine rotating speed is determined according to the judgment result and the preset roaring frequency, the target engine is controlled to rotate according to the target engine rotating speed, and compared with an existing brake roaring adjustment scheme which is high in hardware changing cost and long in development and verification period, the method has the advantages that the hardware changing cost is high on the basis of not changing hardware; by monitoring the motor recovery torque corresponding to the target motor in real time and dynamically regulating and controlling the rotating speed of the engine, the roaring frequency of the whole vehicle is avoided, and the braking roaring problem of the whole vehicle is thoroughly solved.

    本发明属于车辆技术领域,公开了一种发动机转速控制方法、设备、存储介质及装置,本发明在目标车辆处于串联发电模式且检测到制动踏板信号时,获取目标车辆的目标电机对应的电机回收扭矩;根据电机回收扭矩与预设悬置扭矩判断是否需要对发动机转速进行补偿,获得判断结果;根据判断结果和预设轰鸣频率确定目标发动机转速,并根据目标发动机转速控制目标发动机转动,相较于现有制动轰鸣调整方案中更改硬件成本较高且开发验证周期长,本发明通过不改变硬件的基础上,通过实时监控目标电机对应的电机回收扭矩并动态调控发动机转速,避开整车轰鸣频率,彻底解决整车制动轰鸣问题。
