Problems solved by technology

However, under normal circumstances, in order to balance the torque of the engine and the torque of the motor, the torque of the motor is often adjusted first according to the power of the engine sent by the vehicle controller, and then the power of the engine is adjusted, which will cause the response time of the engine power switching longer

Abstract

The application discloses a control method and related products. The control method includes: obtaining the first target power; obtaining the target speed and target torque corresponding to the first target power according to the external characteristics of the engine; adjusting the speed of the engine according to the target speed, and adjusting the torque of the motor according to the target torque; obtaining the actual torque of the engine; When the actual torque of the engine does not match the target torque, the difference between the torque of the motor and the actual torque of the engine is adjusted within a first torque difference range. In this way, the rotational speed of the engine is adjusted while the torque of the electric motor is adjusted, and the rotational speed of the engine does not need to be adjusted after the torque of the electric motor is adjusted, thereby reducing the response time of power switching. And after adjusting the power of the engine, when the actual torque of the engine is different from the target torque, the torque of the motor is adjusted to the difference with the actual torque of the engine within the first torque difference range, so that the torque of the motor and the engine torque balance.

Description

technical field [0001] The present application relates to the technical field of engine control, in particular to a control method and related products. Background technique [0002] In related technologies, when the vehicle needs to switch the power of the engine, the auxiliary power unit of the vehicle adjusts the power of the engine according to the power sent by the vehicle controller. However, under normal circumstances, in order to balance the torque of the engine and the torque of the motor, the torque of the motor is often adjusted first according to the power of the engine sent by the vehicle controller, and then the power of the engine is adjusted, which will cause the response time of the engine power switching longer. Contents of the invention [0003] In order to reduce the power switching response time of the engine, embodiments of the present application provide a control method and related products. [0004] In the first aspect, the embodiment of the pres...
