Abstract

The invention discloses a control method and a related product. The control method comprises the steps of obtaining first target power; obtaining a target rotating speed and a target torque corresponding to the first target power according to the external characteristics of an engine; adjusting the rotating speed of the engine according to the target rotating speed and adjusting the torque of themotor according to the target torque; acquiring the actual torque of the engine; when the actual torque of the engine does not conform to the target torque, adjusting the torque of the motor to a difference value with the actual torque of the engine within a first torque difference value range. In this way, the rotating speed of the engine is adjusted while the torque of the motor is adjusted, therotating speed of the engine does not need to be adjusted after the torque of the motor is adjusted, and the power switching response time is shortened. In addition, after the power of the engine isadjusted, when the actual torque of the engine is different from the target torque, the torque of the motor is adjusted to enable the difference value between the torque of the motor and the actual torque of the engine to be within the first torque difference value range, and therefore the torque of the motor and the torque of the engine can be kept balanced.

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...
