Title: (EN) Electric vehicle
(ZH) 电动车辆
Abstract: front page image
(EN) An electric vehicle, comprising a drive shaft outputting a drive force and at least two motors outputting a power to the drive shaft. The electric vehicle further comprises a control means which, when either of the motors is brought into a non-drive state, limits a torque to the motor in a drive state based on the counter electromotive force of the motor in the non-drive state. Thus, even when the electric vehicle in which a same shaft is driven by two or more motors runs continuously with one motor brought in the non-drive state, the circuit parts of an inverter can be properly protected.
(ZH)

一种电动车辆,包括输出驱动力的驱动轴和至少两个将动力输出到该驱动轴的电机,还包括控制装置,当任一个电机处于非驱动状态时,该控制装置基于处于所述非驱动状态的电机的反电动势,对处于驱动状态的电机执行扭矩限制。在同一根轴由两个或更多电机驱动的电动车辆中,即使在一个电机处于非驱动状态的情况下继续车辆行驶时,也能够适当地保护诸如逆变器的电路元件。
