Description

One-stop type vehicle intelligent maintenance system and use method thereof

Technical Field

The invention belongs to the field of intelligent equipment, and particularly relates to a one-stop vehicle intelligent maintenance system and a using method thereof.

Background

With the development of socioeconomic performance and the increasing living standard of people, the original luxury goods of automobiles are introduced into more and more families. According to the statistics of the bureau of transportation and administration of Ministry of public Security, the number of motor vehicles in China reaches 2.85 hundred million by 2016 and 1.84 hundred million of automobiles. When the automobile is used for a period of time, the automobile needs to be repaired or maintained so as to maintain the continuous use of the automobile.

At present, a new view of the automobile industry is as follows: "repair with maintenance, prolong life", this has put forward higher demands to the maintenance enterprise, but the maintenance enterprise does not have such condition yet at present to satisfy the demand of market. Taking an automatic gearbox as an example, after 4-6 kilometers or 2 years, oil needs to be replaced, because the automatic gearbox is controlled without hydraulic transmission, the gearbox can generate abrasion of mechanical elements, aging of sealing elements, fatigue of springs and the like in long-time use, so that the gear shifting quality of the gearbox is affected by the coordination imbalance of software and hardware of the gearbox, and the gearbox can be abnormal if oil cannot be replaced in time. The current automatic gearbox oil change equipment in the market is complex in model, cannot provide information such as gearbox model, oil change amount and oil model which are equipped by each vehicle model, can check the oil amount and check the standard, cannot accurately control the accuracy of the oil change amount, but manually adjusts an oil inlet and outlet valve to control equivalent oil change, manual control is improper, the gearbox is damaged due to excessive or insufficient oil filling, and faults of the automatic gearbox caused by excessive or insufficient oil filling are frequent.

The existing oil change machine can only change oil simply, and has no guide function, no heating function and no diagnosis function. Without the guiding function, the oil changer does not know what kind of the tank type is used for the automatic transmission, and does not know what kind of oil is used, so that the oil change may be caused to be wrong, and the automatic transmission may be damaged. The thermostat has no heating function, and when the vehicle is in contact with the thermostat, the oil temperature of the whole oil way is reduced when the oil of the automatic gearbox of the automobile is interacted with cold oil of an oil changing machine, so that the thermostat is closed, and the phenomenon that the oil cannot be changed is caused.
