Air conditioning comfortableness control system of hybrid car based on start-stop mode

Abstract

The invention provides an air conditioning comfortableness control system of a hybrid car based on a start-stop mode, comprising an air conditioning controller, an outside temperature sensor, an evaporimeter temperature sensor, a heating ventilation air conditioning assembly, an engine control unit ECU, an engine and a compressor. The air conditioning controller determines whether the hybrid car is permitted to idling halt or not through the judgment of the inside climate comfortableness. When an air conditioning system is permitted to idling halt, under the situation that other conditions are met, the engine is controlled to halt by the engine control unit; when the air conditioning system is not permitted to idling halt, the engine is not controlled to halt by the engine control unit, when the engine is already halted, the engine is controlled to restart by the engine control unit, and the compressor is started to lead the air conditioning system to go on working to keep the inside climate comfortableness. The air conditioning comfortableness control system is improved based on the traditional car air conditioning system, the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to a control method of an automobile air-conditioning system. Background technique [0002] The air conditioning system is a very common configuration on modern cars. Usually, the air conditioner driving device of the start-stop mode hybrid electric vehicle is that the engine output shaft directly drives the compressor to run through the belt. Once the engine stops, the air conditioner compressor and the water pump will stop, and the inevitable problem is the loss of the comfort adjustment ability of the air conditioner. . In order to solve the problem of ride comfort, the usual solution is to use electric air conditioners to drive the air conditioner completely by electric energy; or use a mechanical / motor dual drive device, that is, the engine drives the air conditioner when the engine is working normally, and the motor drives the air conditioner when the engine is stopped. Drive the air conditioner. [0003] However, electri...

Problems solved by technology

[0003] However, electric air conditioners and mechanical / electric dual-purpose air conditioners have some disadvantages: first, they are expensive, and the price of electric air conditioners or mechanical / electric air conditioners is generally between 10,000 and 20,000 yuan.

Another problem is that the capacity of batteries on hybrid electric vehicles is relatively small at present, and the power of the batteries is only enough to drive the electric air conditioner for a short period of time, which is of little practical significance

[0004] In addition, for the judgment of the climate comfort in the car, the usual solution is to add an interior temperature sensor on the instrument panel, but adding an interior temperature sensor with an induced draft fan and the sensor connection harness requires an increase of about 30 to 40 cost of yuan
