Abstract

The invention discloses a fault diagnosis processing system and method for EMT automatic transmission of a pure electric commercial vehicle. For the automatic transmission for EMT, a system comprisinga fault diagnosis module, a fault acquisition module, a fault processing module, a fault analysis module and a fault application module is designed. According to the system, all faults of related parts of the EMT are counted; finally, the service life of the part, the service life of the part corresponding to each fault and external information are obtained, so that a worker or a driver and passengers can clearly see possible faults of the speed changer in operation, and then relevant treatment is carried out in advance; the system analyzes and processes specific faults of the EMT automatic transmission of the pure electric commercial vehicle, so that various problems caused by faults of the automatic transmission are solved effectively.

Description

【Technical field】 [0001] The invention belongs to the field of new energy system power, and relates to a fault diagnosis and processing system and method for an EMT automatic transmission of a pure electric commercial vehicle. 【Background technique】 [0002] With the decline of air quality in recent years, the air pollution in major cities is serious; the central and local governments have issued a series of policies to promote the rapid development of new energy vehicles, and the market ownership has increased year by year. Due to the large mass of pure electric commercial vehicles, in order to meet the vehicle power and road requirements, the technical route of drive motor + EMT automatic transmission is often used (EMT is the abbreviation of automatic transmission for new energy vehicles). [0003] With the gradual entry of new energy commercial vehicles into the market, the reliability and economy of vehicles have attracted the attention of end customers and operators, e...
