A heating control system capable of automatic demisting

Abstract

The invention relates to the technical field of automobile electrical system design, in particular to a warm air control system capable of automatic demisting. The data output terminals of the ambient temperature sensor, light sensor, and humidity sensor are respectively connected to the data input terminal of the instrument controller, the driving signal output terminal of the instrument controller is connected to the coil of the action conversion relay, and the fan switch is connected to the ACC gear power supply of the vehicle. The other end is connected to the normally closed contact, normally open contact of the action conversion relay, the normally open contact of the defrost relay, and the normally closed contact of the defrost relay through the heater switch, and the normally closed contact of the defrost relay One end is connected with one end of the fan through an electric heater. Automatically control the on-off of the action relay through temperature, light, and humidity data, thereby controlling whether the electric heater in the circuit is working or not, so that the warm air is automatically switched to normal temperature air when the vehicle is fogged, and the normal temperature air is automatically switched to warm air after the fog is eliminated. .

Description

technical field [0001] The invention relates to the technical field of automobile electrical system design, in particular to a warm air control system capable of automatic demisting. Background technique [0002] In winter, when the vehicle is running with the warm air turned on, the front and rear windshields are prone to fogging, which seriously affects the driver's vision and is prone to safety accidents. Usually the driver will manually wipe the interior glass, wipe off the water mist or water droplets. Especially for long-distance vehicles or buses running in the early morning in the city, the driver needs to frequently manually wipe off the water mist on the front windshield to maintain a clear view ahead, but frequent wiping of the water mist seriously affects the driving safety of the driver . For the rear windshield, usually the driver cannot wipe the water mist due to inconvenient operation, thus causing the blurred vision of the rear windshield, which also affec...
