One embodiment of the present invention is a method for controlling an electric vehicle having a power consumption suppression mode and a travel performance mode as a control mode for distributing a requested torque to a front torque and a rear torque and adjusting the distribution of the requested torque. In the control method for the electric vehicle, in the case of the power consumption suppression mode, the requested torque is distributed to the front torque or the rear torque more, and in the case of the driving performance mode, the front torque or the rear torque to which the requested torque is distributed more in the power consumption suppression mode is reduced. Furthermore, the temperature of the front drive system or the rear drive system is acquired, and the output of the front torque or the rear torque is limited by setting an upper limit value corresponding to the temperature of the front drive system or the rear drive system for the distributed front torque or rear torque. Furthermore, when the control mode is the power consumption suppression mode, the control mode is switched to the driving performance mode after the upper limit value is reduced and before the output of the front torque or the rear torque is limited to the upper limit value.

    本发明的某个方式为如下电动车辆的控制方法,即,作为将请求转矩分配给前转矩和后转矩且调整请求转矩的分配的控制模式,具有电力消耗抑制模式以及行驶性能模式。关于该电动车辆的控制方法,在电力消耗抑制模式的情况下,请求转矩被较多地分配给前转矩或后转矩的任一者,在行驶性能模式的情况下,降低在电力消耗抑制模式下较多地分配了请求转矩的前转矩或后转矩。另外,获取前驱动系统或后驱动系统的温度,针对分配后的前转矩或后转矩,设定与前驱动系统或后驱动系统的温度相应的上限值,由此限制前转矩或后转矩的输出。而且,在控制模式为电力消耗抑制模式的情况下,在上限值降低之后,在前转矩或后转矩的输出被限制为上限值之前,将控制模式切换为行驶性能模式。
