Problems solved by technology

This solution is actually to test the performance of the air conditioner under different typical working conditions to evaluate the cooling performance of the air conditioner. However, the acquisition of typical working conditions requires huge data support, and performance tests under various preset test environments There are time-consuming and labor-intensive defects, and this test method cannot accurately reflect the overall performance of automotive air conditioners

Abstract

The invention relates to the technical field of evaluation of automobile air conditioners, in particular to a method and system for evaluating controllability of an automatic air conditioner of a passenger car. A to-be-tested car is arranged on a test bench, and an air conditioner of the to-be-tested car is set to be in an AUTO mode; a car speed compensation value is obtained according to temperature changes in a passenger compartment at different car speeds; a sunlight compensation value is obtained according to temperature changes in the passenger compartment at different sunlight intensities; a set temperature characteristic value is obtained according to temperature changes in the passenger compartment at different set air conditioner temperatures; a double-temperature-zone independent control value is obtained according to temperature changes in the passenger compartment under different set air conditioner temperatures in a double-temperature zone; the car speed compensation value, the sunlight compensation value, the set temperature characteristic value and the double-temperature-zone independent control value are weighted to obtain evaluation parameters; and the evaluation parameters are compared with set values to obtain the evaluation grade of the controllability of the automatic air conditioner of the passenger car. The whole scheme can truly reflect the comprehensive control performance of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of evaluation of automobile air conditioners, in particular to a controllability evaluation method and evaluation system of an automatic air conditioner for passenger cars. Background technique [0002] Since the first use of automatic air conditioning in passenger cars in the 1970s, its practicality and cost-effectiveness have continued to improve, and it has become a standard feature of most passenger cars. In the field of design, there are many patents and technologies for the control logic of automatic air conditioning. In the field of performance evaluation, the maximum performance of vehicle air conditioners, such as cooling and heating, has a mature indoor environment simulation + outdoor road test evaluation method, but for the controllability of vehicle automatic air conditioning, for example, for different vehicle speeds, different lighting and other scenarios There is still a lack of a complete t...
