The invention discloses a vehicle four-wheel drive control method and electronic equipment. The method comprises the steps that vehicle parameters are acquired; when the vehicle runs in the straight direction, whether the current mode is an accelerator control mode or a rotating speed difference control mode is determined according to vehicle parameters; and if the current mode is the acceleratorcontrol mode, the rear wheel torque is controlled according to the accelerator opening degree, and if the current mode is the rotating speed difference control mode, the rear wheel torque is controlled according to the wheel speed difference of the front and rear wheels. According to the driving requirements of all working conditions, the working conditions suitable for accelerator opening controland front and rear wheel rotating speed difference control are defined, and the advantages of accelerator opening control and front and rear wheel rotating speed difference control are combined. During starting and accelerating at a large accelerator opening degree, the rotating speed difference is effectively reduced. The rotating speed difference is effectively eliminated during starting and driving at a low accelerator opening degree. At a high speed, frequent intervention of a four-wheel drive system is avoided, and overheating protection of four-wheel drive parts is effectively prevented.

    本发明公开一种车辆四驱控制方法及电子设备,方法包括:获取车辆参数;在车辆直向行驶时,根据车辆参数确定当前模式为油门控制模式或者转速差控制模式;如果当前模式为油门控制模式,则根据油门开度控制后轮扭矩,如果当前模式为转速差控制模式,则根据前后轮的轮速差控制后轮扭矩。本发明根据各工况的驾驶需求,明确了油门开度控制和前后轮转速差控制两种模式各自适合的工况,结合了两者的优点。在大油门起步和加速时,有效降低转速差。在低油门起步和行驶,有效消除转速差。在高速时避免四驱系统频繁介入,有效防止四驱零件过热保护。
