좌우 모터(22A, 22B) 구동용의 축전기(24)의 잔류 용량이 조금이라도 남아 있을 때, 배터리(24)의 과방전을 보호하고, 또한 차량(10)의 선회성 구동성을 향상시키는 차량(10)을 제공한다. ECU(26)는, 배터리(24)의 온도 또는 방전 제한 전력(Pdlmt)에 기초하여 정해지는 좌측 동력(F1)과 우측 동력(F2)의 차이의 최대치인 차 토크 상한치(ΔTTlmt)를 넘지 않도록 좌측 모터(22A) 및 우측 모터(22B)의 좌측 동력(F1) 및 우측 동력(F2)을 제어한다. 배터리(24)가 저온 등에서 방전 전력(Pd)이 제한되는 때에, 방전 제한 전력(Pdlmt)에 기초하여 좌측 동력(F1)과 우측 동력(F2)의 차이를 제어함으로써, 배터리(24)의 손상의 우려를 방지하면서 차량(10)의 선회성을 향상시킨다.

    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).
