In the present invention, either an in-phase mode in which the positive and negative output torques of each electric motor are consistent with each other or an out-of-phase mode in which the positive and negative output torques of each electric motor are different from each other is set as a control mode for determining the torque distribution of a vehicle. When the control mode is switched between the in-phase mode and the out-of-phase mode, distribution adjustment control for adjusting torque distribution is executed, and in the distribution adjustment control, during idle running of a first output torque of one of positive and negative reverses during switching of the control mode, a second output torque of one of positive and negative non-reverses is adjusted so as to approach a total request torque.
本发明设定各电动机的输出扭矩的正负相互一致的同相模式和各电动机的输出扭矩的正负相互不同的异相模式中的任意一种,作为确定车辆的扭矩分配的控制模式,执行使控制模式在同相模式和异相模式之间相互转换时调节扭矩分配的分配调节控制,在分配调节控制中,在控制模式的转换时正负反转的一方的第一输出扭矩的空转期间,将正负不反转的一方的第二输出扭矩调节为接近总请求扭矩。
