Heating ventilation and air conditioning electric control system and hybrid power automobile

Abstract

The invention discloses a heating ventilation and air conditioning electric control system. The heating ventilation and air conditioning electric control system comprises an air conditioning controller, an air conditioning device and an automobile body controller, wherein the automobile body controller can receive a temperature signal detected by an automobile external environment temperature sensor and transmits an environment temperature signal to the air conditioning controller; the air conditioning device feeds back an evaporator temperature signal to the air conditioning controller; the system is also provided with an economic mode press button connected to the air conditioning controller and an automobile internal temperature sensor; the economic mode press button is used for receiving an economic mode operation requirement of a user; and the air conditioning controller controls the system to operate in different operation modes according to the environment temperature signal and/or the evaporator temperature signal and/or automobile internal temperature information and the state of the economic mode press button. By the heating ventilation and air conditioning electric control system, fuel economy of the hybrid power automobile can be optimized, so that heating ventilation and air condition service can be provided intelligently, comfort degree in the automobile is improved, friendly operation is provided, and satisfaction degree is improved.

Description

【Technical field】 [0001] The invention relates to an optimized control design for a heating, ventilation and air-conditioning electric control system of a weak / medium hybrid electric vehicle, and belongs to the field of electric control system integration and control strategy development of a hybrid electric vehicle. 【Background technique】 [0002] With the increasing pressure of energy depletion and environmental protection, the energy saving and emission reduction of automobiles has become the driving force for the development of the automobile industry. Therefore, hybrid vehicles have emerged along with the energy saving and emission reduction of automobiles. Gasoline-electric hybrid vehicles use fuel-driven and electric-driven driving methods, and coordinate the two driving methods through reasonable control strategies to achieve higher fuel economy and emission characteristics. Typically, when a hybrid car starts or runs at a low speed, it only relies on electric power ...
