AI Technical Summary

Technical Problem

Existing automotive thermal management systems have poor water pump life management and pose safety hazards. Users have difficulty understanding the water pump's operating status in a timely manner, leading to potential safety risks.

Method used

By obtaining the actual running time and design service life of the water pump, the equivalent running time and remaining service life are calculated, and the maximum speed is set according to the service life threshold. The operating speed of the water pump is controlled in real time, and the user is reminded to perform timely maintenance through prompt messages.

Benefits of technology

By precisely managing the water pump's operating status, distortion in runtime records is reduced, the water pump's lifespan is extended, and the safety and convenience of the vehicle are improved.

Abstract

The application discloses a kind of automobile thermal management system water pump control method, computer device and storage medium, including according to the actual running length of water pump to determine equivalent running length, according to equivalent running length and design service life to determine equivalent residual life, whenever equivalent residual life reaches a life threshold, according to the highest speed corresponding to the life threshold to the running speed of water pump is controlled step etc..The application reduces the distortion of the running length obtained by real-time recording, the equivalent residual life calculated according to the equivalent running length is closer to the real residual life of water pump, can carry out hierarchical fine management to the running speed of water pump, is conducive to the working characteristic curve of water pump more close to its service life curve, is conducive to avoiding the nonlinear decline of water pump service life, is conducive to water pump longer service, maintain the safety and convenience of car.The application is widely applied in the field of automobile technology.
