摘要： Provided is a vehicle (10) in which overdischarge of a battery (24) is protected and turning drivability of the vehicle (10) is improved when there is even a little remaining capacity in a storage capacitor (24) for driving left and right electric motors (22A, 22B). An ECU (26) controls the left motive force (F1) and the right motive force (F2) of the left electric motor (22A) and the right electric motor (22B) so as not to exceed a differential torque upper limit value (ΔTTlmt), which is the maximum value of the difference between the left motive force (F1) and the right motive force (F2) established on the basis of the temperature or discharge limit power (Pdlmt) of the battery (24). When the battery (24) is at a low temperature or the like and the discharge power (Pd) is limited, the difference between the left motive force (F1) and the right motive force (F2) is controlled on the basis of the discharge limit power (Pdlmt), whereby the turnability of the vehicle (10) is improved while preventing the risk of damage to the battery (24).
摘要翻译： 本发明提供一种车辆（10），其中当用于驱动左右电动机的储能电容器（24）中甚至有少量剩余电量时，电池（24）的过放电受到保护并且车辆（10）的转向驾驶性能得到改善 马达（22A，22B）。 ECU26将左侧电动机22A和右侧电动机22B的左侧的动力F1和右侧的动力F2控制为不超过差动转矩上限值ΔTTlmt ），这是基于电池（24）的温度或放电极限功率（Pdlmt）建立的左动力（F1）和右动力（F2）之间的差值的最大值。 当电池（24）处于低温等并且放电功率（Pd）被限制时，基于放电来控制左动力（F1）和右动力（F2）之间的差值 限制功率（Pdlmt），由此改进车辆（10）的可转动性，同时防止损坏电池（24）的风险。

摘要： Provided is a vehicle (10) in which overdischarge of a battery (24) is protected and turning drivability of the vehicle (10) is improved when there is even a little remaining capacity in a storage capacitor (24) for driving left and right electric motors (22A, 22B). An ECU (26) controls the left motive force (F1) and the right motive force (F2) of the left electric motor (22A) and the right electric motor (22B) so as not to exceed a differential torque upper limit value (”TTlmt), which is the maximum value of the difference between the left motive force (F1) and the right motive force (F2) established on the basis of the temperature or discharge limit power (Pdlmt) of the battery (24). When the battery (24) is at a low temperature or the like and the discharge power (Pd) is limited, the difference between the left motive force (F1) and the right motive force (F2) is controlled on the basis of the discharge limit power (Pdlmt), whereby the turnability of the vehicle (10) is improved while preventing the risk of damage to the battery (24).
