The invention belongs to the technical field of new energy vehicle safety control, and particularly relates to a new energy vehicle and a vehicle output torque control method and device thereof. The method comprises the following steps: judging whether the whole vehicle is in an unexpected acceleration state/unexpected deceleration state in a driving mode/non-driving mode or not by adopting a corresponding judgment method according to an operation mode of the whole vehicle and obtained operation parameters of the whole vehicle; and when it is determined that the whole vehicle is in an unexpected acceleration state in a driving mode, an unexpected deceleration state in the driving mode or an unexpected acceleration state in a non-driving mode, the output torque of the whole vehicle is controlled to be 0, so that the whole vehicle is protected, the whole vehicle is processed in time under the conditions, and the driving experience of the whole vehicle is guaranteed. And safety accidents are prevented.

    本发明属于新能源车辆安全控制技术领域,具体涉及一种新能源车辆及其车辆输出扭矩控制方法及装置。该方法依据整车所处的运行模式和获取的整车运行参数,采用相应的判别方法,判断整车是否处于驱动模式/非驱动模式下的非预期加速状态/非预期减速状态,并在确定整车处于驱动模式下的非预期加速状态、驱动模式下的非预期减速状态、或者非驱动模式下的非预期加速状态时,控制整车输出扭矩为0,以实现对整车的保护,以便在出现这些情况下及时对整车进行处理以保证整车驾驶体验,防止安全事故发生。
