The embodiment of the invention provides a control method for the front axle connection state of a four-wheel drive vehicle and a vehicle control unit, and the method comprises the steps: obtaining the front axle connection state of the vehicle and the current working condition of the vehicle in the vehicle driving process; if it is determined that the front axle connection state needs to be switched according to the current working condition, the front axle connection state is switched based on a preset switching strategy; therefore, whether the connection state of the front axle needs to be switched or not can be judged in real time based on the connection state of the front axle of the vehicle and the current working condition in the running process of the vehicle, so that the front axle is normally disengaged when the vehicle is in an economic mode, the power consumption is optimal, and the endurance mileage is increased; a front axle can be normally combined in a power mode, so that the maximum acceleration capability of a vehicle power system is improved; and the front axle connection state can be flexibly switched according to the current working condition, and the operation stability and economical efficiency of the vehicle are improved.

    本发明实施例提供了一种四驱车辆前轴连接状态的控制方法及整车控制器,方法包括:在车辆行驶过程中,获取车辆的前轴连接状态以及获取所述车辆的当前工况;若根据所述当前工况确定需要对所述前轴连接状态进行切换,则基于预设的切换策略对所述前轴连接状态进行切换;如此,在车辆行驶过程中可基于车辆的前轴连接状态及当前工况来实时判断是否需要对前轴连接状态进行切换,这样可确保车辆在经济模式下将前轴常脱开使得电耗最优,提升续航里程;可在动力模式使前轴常结合,提高车辆动力系统的最大加速能力;也即可根据当前工况灵活切换前轴连接状态,提高车辆的操稳性及经济性。
