EARLY FAULT DETECTION FOR AN EPS SYSTEM

摘要

Methods and apparatus are provided for an improved system for early detection of a fault in an EPS system for a vehicle. The apparatus includes a steering gear assembly including a temperature sensor and a pressure sensor for sensing within the steering gear assembly. A controller determines a relationship between the temperature value and the pressure value, and also determines whether the relationship is within a threshold of a reference relationship. The controller can provide an indication or message on a display when the relationship is not within the threshold of the reference relationship. The method includes monitoring a temperature and a pressure associated with an electronic power steering system for a vehicle during operation of the vehicle and determining a relationship between the temperature and the pressure. A fault indication or message is presented on a display when the relationship exceeds a threshold value from a reference relationship.

1. A method, comprising:
monitoring, by a processor, a temperature associated with an electronic power steering system for a vehicle during operation of the vehicle; monitoring, by the processor, a pressure associated with an electronic power steering system for the vehicle during operation of the vehicle; determining, by the processor, a relationship between the temperature and the pressure; and presenting an indication or message on a display when the relationship exceeds a threshold value.
