本发明涉及一种四轮驱动的混合动力机动车辆的驱动扭矩分配方法。该车辆包括由第一电机以及通过第一联接系统而由热机驱动的第一车桥,以及具有第二电机的第二车桥。该方法包括以下步骤:步骤(a),根据第一和第二车桥之间的第一扭矩分配对车辆进行驱动(100);步骤(b),对改变运行状态以及热机与第一车桥的联接状态的需求进行预测(102),该需求要求第一车桥和第二车桥之间的第二扭矩分配;然后步骤(c),通过修改由第一电机在第一轴上产生和第二电机在第二轴上产生的扭矩设定值,从第一扭矩分配向第二扭矩分配进行转变(108)。

    The invention relates to a method for drive torque splitting in a hybrid motor vehicle having four drive wheels. The vehicle has a first drive train driven by a first electrical machine, and by a heat engine via a first coupling system; and a second drive train driven by a second electrical machine. The method comprises the following steps: (a) driving (100) the vehicle according to a first torque split between the first and second drive train; (b) anticipating (102) a need to change the state of operation and the state of coupling of the heat engine to the first drive train, which requires a second torque split between the first drive train and the second drive train; and (c) changing (108) from the first to the second torque split by modifying a torque set point output by the first electrical machine to the first axle, and the second electrical machine to the second axle.
