Intelligent air-conditioner fault reminding system and reminding method for automobiles

Abstract

The invention discloses an intelligent air-conditioner fault reminding system and a reminding method for automobiles, and belongs to the technical field of automobile manufacturing. The system comprises a fault information acquisition module, wherein the fault information acquisition module is connected with a plurality of sensors and a plurality of executors, the fault information acquisition module is connected with a fault grade classification module through a fault code storage module, and the fault grade classification module is connected with a meter; a CAN bus connected with the fault code storage module is provided with the diagnosis interface which is connected with a diagnosis instrument in an insertion manner. The method comprises the following steps: acquiring voltage signals of the sensors and the executors by the fault information acquisition module in real time; analyzing and judging the voltage signals and distributing the voltage signals to the fault grade classification module through the fault code storage module and then performing classification and displaying on the meter; reading and displaying fault information on the fault code storage module through the diagnosis instrument for car repairing. According to the intelligent air-conditioner fault reminding system and the reminding method for automobiles disclosed by the invention, the problem that minor faults of an existing automotive intelligent air-conditioner are difficult to be found out, severe faults cannot be found out in time and fault sources are difficult to search can be solved.
