The embodiment of the invention discloses a control method and device, equipment and a computer readable storage medium. The method comprises the steps that when a vehicle is in a four-wheel-drive state, whether the vehicle has a four-wheel-drive requirement or not is detected in real time; and if it is detected that the vehicle does not have the four-wheel-drive requirement, the driving motor is controlled to reduce the output preset torque, and the engine is controlled to increase the torque of the numerical value corresponding to the output preset torque till the torque output by the driving motor is zero, so that the vehicle exits the four-wheel-drive state. The four-wheel-drive state exit logic is added, whether the vehicle has the four-wheel-drive requirement or not is detected in real time, the torque of the drive motor is reduced in time when the vehicle has no four-wheel-drive requirement, meanwhile, the torque of the engine is equivalently increased, so that unnecessary four-wheel-drive energy consumption is saved, the corresponding output torque is increased or decreased by the preset numerical value, and the vehicle driving efficiency is improved. Traffic safety accidents caused by large change of the corresponding output torque of the vehicle are avoided, so that the vehicle safely quits the four-wheel-drive state, and timeliness and safety of the vehicle quitting the four-wheel-drive state are guaranteed.
本申请的实施例公开了一种控制方法及装置、设备、计算机可读存储介质。本申请方法包括:在车辆处于四驱状态下,实时检测车辆是否有四驱需求;若检测到车辆无四驱需求,则控制驱动电机减少输出预设扭矩,并控制发动机增加输出预设扭矩对应数值的扭矩,直至驱动电机输出的扭矩为零值,以使车辆退出四驱状态。本申请增设四驱状态退出逻辑,通过实时检测车辆是否有四驱需求,及时在车辆无四驱需求时降低驱动电机的扭矩,同时等量增加发动机的扭矩,以节省不必要的四驱能耗,并且对相应输出扭矩进行预设数值的增减,避免车辆因相应输出扭矩的大幅度变化而发生行车安全事故,使得车辆安全地退出四驱状态,保障了车辆在退出四驱状态时的及时性和安全性。
