Automatic constant-temperature control method for automotive air conditioning controller

Abstract

The invention discloses an automatic constant-temperature control method for an automotive air conditioning controller, which specifically comprises the following steps: 1) determining a hybrid air door motion formula interval by an automotive air conditioning controller according to the input part of an external environment temperature sensor; 2) comprehensively calculating the stop position of hybrid air door feedback voltage according to the input part of an internal temperature sensor and a set temperature; 3) calculating the current external temperature zone according to the processor of the automotive air conditioning to determine a hybrid air door motion interval; and 4) calculating the voltage value of the current hybrid air door position according to the hybrid air door calculation formula, automatically regulating the air discharge speed of an air door, and enabling the inside of an automobile to be constantly kept at the set temperature, wherein the voltage calculation formula of the hybrid air door is P=[Kp-(Tset+Kc)] / Ka. With the method, the temperature in the automobile is kept to be constant, operation to the automotive air conditioning controller by a driver is reduced, the comfort experience to users by automotive environment is improved, and the comfort performance of the finished automobile is improved.

Description

technical field [0001] The invention relates to an automatic constant temperature control method, in particular to an automatic constant temperature control method for an automobile air conditioner controller. Background technique [0002] With the rapid development of China's economy and automobile industry, the penetration rate of automobiles has been greatly increased. Automobile air conditioners are not only a symbol of the improvement of people's living standards but also one of the important symbols of improving the competitiveness of automobiles. Today, people pay more attention to the quality of life, protect the environment, and save energy. People put forward higher requirements for the energy saving and thermal comfort of automotive air conditioners. [0003] At present, most of the car air-conditioning controllers are manual brushed and electric control panels, and there are relatively few automatic controllers. These air-conditioning controllers generally have ...

AI Technical Summary

Problems solved by technology

These air-conditioning controllers generally have the following problems: 1. The heating and cooling temperature cannot be automatically adjusted; 2. The temperature inside the car cannot be kept constant within a small range; 3. The user cannot feel comfortable, and will always be overheated or overcooled; The logic of some automatic air conditioners is similar to that of electric air conditioners. It controls the mixing damper and compressor control method according to the ambient temperature difference. In this way, due to the temperature hysteresis of the sensor, the air outlet changes from hot to cold, resulting in a significant decrease in user comfort.
