Abstract

The invention provides an in-vehicle air conditioner control method which comprises the following steps: S10, detecting distance relationship between an automobile and a tunnel, and transmitting tunnel signals when preset distance is arrived; S20, giving out circulation mode control signals according to the received tunnel signals; S30, controlling the circulation mode of an air conditioner according to the received circulation mode control signals. The invention further provides an air conditioner control system. By means of the in-vehicle air conditioner control method, the tunnel signals and the circulation mode control signals are transmitted, so that the air conditioner is controlled to enter inner circulation before the vehicle enters a tunnel, harmful gas in the tunnel can be thoroughly prevented from entering the vehicle, and health of drivers and passengers can be ensured.

Description

technical field [0001] The invention relates to a control system and method for an air conditioner in a vehicle. Background technique [0002] Because the road tunnel is a relatively closed space, the car exhaust remains seriously, so the air pollution in the tunnel is serious, which endangers the health of the drivers and passengers. Therefore, before the vehicle enters the tunnel, it can be effectively Prevent harmful gas in the tunnel from entering the car, and ensure that drivers and passengers are not harmed by harmful gas. [0003] The existing technology uses sensors to detect the air quality in the car. When the harmful gas in the car reaches a certain threshold, the inner and outer circulation of the air are switched. However, at this time, some harmful air has entered the car. This technical method has obvious lag sex. Contents of the invention [0004] The invention provides an air-conditioning control system and method for solving the technical problem of aut...
