Problems solved by technology

However, considering the economical operation of the whole vehicle, most of the power of the existing hybrid vehicle is provided by the drive motor, so that the power provided by the engine is relatively small, and thus the heat generated is less, which cannot meet the requirements of the air conditioner. The need for rapid heating

Embodiment Construction

[0038] In the prior art, the heat of the cooling water of the engine can be used for heating of the air conditioner of the hybrid vehicle. However, most of the vehicle power of existing hybrid electric vehicles is provided by the drive motor, so that the power provided by the engine is relatively small, resulting in less heat generated by the operation of the engine, which cannot meet the rapid heating requirements of the air conditioner. The problem of poor thermal effect.

[0039] In order to solve the above-mentioned problems existing in the prior art, the technical solution adopted in the embodiment of the present invention makes the engine run with the full power currently required by the vehicle when receiving the rapid heating request sent by the air-conditioning controller, so that the engine can generate more energy. More heat can meet the needs of rapid heating of vehicle air conditioners and improve user experience.

[0040] In order to make the above objects, feat...

Abstract

The invention discloses an engine power control method for a hybrid power automobile and a hybrid power unit controller. The method includes the steps that when a fast heating requirement sent by an air conditioner controller is received, the whole power needed for normal running of the hybrid power automobile under the current state is calculated; and the calculated whole power needed for normal running of the hybrid power automobile under the current state serves as engine output power which is sent to an engine control unit, and the engine control unit controls an engine to run as the engine output power. The above scheme can meet the fast heating requirement of a vehicle air conditioner, and the using experience of a user is improved.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine power control method and a hybrid unit controller of a hybrid electric vehicle. Background technique [0002] Hybrid Vehicle (Hybrid Vehicle), in a broad sense, refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. common drive system. Due to its energy-saving and low-emission characteristics, hybrid vehicles have become a focus of automobile research and development, and have begun to be commercialized. [0003] In the prior art, the heat of the cooling water of the engine can be used for heating of the air conditioner of the hybrid vehicle. However, considering the economical operation of the whole vehicle, most of the power of the existing hybrid vehicle is provided by the drive motor, so that the power provided by the engine is relatively small, and thus the heat generated is less, which...
