The invention provides a torque control method of a hybrid vehicle, a vehicle control unit and the hybrid vehicle, the method is applied to the technical field of vehicle control, and the method comprises the steps that the current gear of the hybrid vehicle and the vehicle state of the hybrid vehicle under the current gear are detected in real time; according to the vehicle state, the next operation mode of the hybrid vehicle under the current gear is judged; requesting the state of the clutch from an automatic transmission control unit (TCU) of the hybrid vehicle according to the next operation mode; requesting torque from a power transmission system of the hybrid vehicle according to the next operation mode after the clutch state request succeeds; the torque includes a positive torque and a negative torque. Torque control in various scenes can be achieved, torque control of the hybrid vehicle without a reverse gear is supported, a reverse gear mechanical structure can be omitted, and therefore the structure of a gearbox in an engine compartment is simpler.

    本发明提供了一种混动车辆的扭矩控制方法、整车控制器、混动车辆,该方法应用于车辆控制技术领域,包括:实时检测混动车辆的当前档位、以及混动车辆在当前档位下的车辆状态;根据车辆状态判断混动车辆在当前档位下的下一运行模式;根据下一运行模式向混动车辆的自动变速箱控制单元TCU请求离合器的状态;在离合器状态请求成功后,根据下一运行模式向混动车辆的动力传动系统请求扭矩;所述扭矩包括正向扭矩和负向扭矩。本发明可实现各种场景下的扭矩控制,支持无倒档齿轮时混动车辆的扭矩控制,可省掉倒档机械结构,从而使发动机舱内变速箱的结构更为简单。
