The hybrid vehicle includes a transmission controller that controls an actual required torque at a wheel end and an engine controller.
Fig. 1 is a flowchart of a method of controlling engine torque of a hybrid vehicle according to an embodiment of the present invention, as shown in fig. 1, the method of the embodiment of the present invention including:
s1, the transmission controller receives an engine torque reference parameter in a hybrid vehicle operating mode.
Specifically, the hybrid vehicle includes an engine and a motor, and may be driven by either the engine or the motor. In an embodiment, the operating modes of the hybrid vehicle may include a series operating mode in which the engine provides only the target torque for power generation and is not directly used to drive the vehicle, and a parallel operating mode in which the engine has both a certain torque for power generation and a part of torque for driving the vehicle.
And S2, the gearbox controller obtains the target engine torque according to the engine torque reference parameter.
The gearbox controller is used for directly controlling the clutch to transmit torque, namely wheel end torque, so that actual wheel end torque requirements can be clear, the gearbox controller sends out engine target torque, the output of the engine target torque is determined according to the actual requirements, the required torque is controlled, and the wheel end torque and the engine target torque are controlled more accurately.
In some embodiments, the engine torque reference parameter is used to generate power in the series operating mode, and the engine torque reference parameter may include an engine requested target torque, and the transmission controller receives the engine requested target torque and uses the engine requested target torque as the engine target torque and sends the engine target torque to the engine controller to control the output torque of the engine.
In other embodiments, in the parallel operating mode, a plurality of engine torque related parameters need to be considered, for example, the engine torque reference parameters may include an engine requested target torque, a wheel end requested target torque, an engine actual torque, and a motor actual torque. The gearbox controller receives the engine request target torque, the wheel end request target torque, the engine actual torque and the motor actual torque, integrates all parameters for matching, and calculates the engine target torque according to the engine request target torque, the wheel end request target torque, the engine actual torque and the motor actual torque. Specifically, the vehicle controller can integrate the vehicle requirements to send out an engine request target torque and a wheel end request target torque, and the transmission controller comprehensively considers the request parameters of the vehicle controller and the actual conditions of the engine and the motor to obtain a matched engine target torque, for example, an optimization table corresponding to each parameter is obtained through a preliminary big data test, and a matched engine target torque is obtained through table look-up, or a calculation model is obtained according to a neural network algorithm, and optimization matching is performed through a prestored calculation model to obtain an engine target torque actually required in the current operation mode.

Since the whole transmission system of the vehicle follows the law of conservation of energy, the gearbox and the main reducer can match the appropriate torque and rotating speed to output to the wheels according to the conditions, and finally convert the torque into speed and acceleration, and the sudden drop of the engine torque does not represent that the torque on the wheels drops together.

Therefore, the vehicle control unit sends the engine request target torque, the wheel end request target torque and the motor actual torque to the gearbox controller, and the gearbox controller receives the engine actual torque; the transmission controller receives the wheel end request target torque as a clutch control basis, calculates the required engine target torque according to the engine request target torque, the wheel end request target torque, the actual engine torque and the actual motor torque in order to realize the target wheel end torque, and sends the engine target torque required to be executed by the engine controller to the engine controller, so that the transmission controller controls the engine, namely, the required driving torque is required according to the required torque. Meanwhile, the transmission controller calculates clutch transmission torque according to the wheel end request target torque to control clutch combination, so that the wheel end torque is transmitted to the wheel end, the wheel end actual torque is obtained, and the wheel end actual torque is fed back to a vehicle control unit of the hybrid vehicle, so that the vehicle control unit can control the vehicle.
