The invention discloses an output torque control method and device and a vehicle, and belongs to the technical field of vehicles. According to the technical scheme, the state parameter of the target vehicle and the environment parameter of the external environment where the target vehicle is located are obtained, and the target vehicle is a hybrid vehicle. And based on at least one of the state parameter and the environment parameter, determining the current operation condition of the engine of the target vehicle, namely determining whether the engine is in the heat damage condition. When the engine is in the heat damage working condition, the temperature of the engine is too high, and faults may occur. At the moment, the output torque of the engine is limited based on the state parameters, namely, the output power of the engine is limited, so that heat generated by the engine is limited, and the purpose of reducing the temperature of the engine is achieved.
本申请公开了一种输出扭矩的控制方法、装置以及车辆,属于车辆技术领域。通过本申请实施例提供的技术方案,获取目标车辆的状态参数和所处外部环境的环境参数,该目标车辆为混合动力车辆。基于该状态参数和环境参数中的至少一项,确定该目标车辆的发动机当前的运行工况,也即是确定该发动机是否处于热害工况下。在该发动机处于热害工况的情况下,也就表示该发动机温度过高,可能发生故障。此时基于状态参数来限制该发动机的输出扭矩,也即是限制发动机的输出功率,从而限制发动机产生的热量,达到降低发动机温度的目的。
