Abstract
In the present disclosure, the method and apparatus for controlling an electronic power steering system include estimating a vehicle's rack force value when the vehicle's cumulative driving distance is greater than or equal to a reference driving distance, comparing the estimated rack force value with learning data, increasing the number of friction detections when the estimated rack force value is greater than the learning data, and outputting an alarm when the number of friction detections is greater than or equal to a critical number, and it may be applied to other exemplary embodiments.
Claims15
A method for controlling an electronic steering system, comprising steps of:
- estimating a rack force value of a vehicle in response to a cumulative driving distance of the vehicle being greater than or equal to a reference driving distance;
- comparing the estimated rack force value with learning data;
- increasing a number of friction detections in response to the estimated rack force value being greater than the learning data;
- and
- outputting an alarm in response to the number of friction detections being greater than or equal to a critical number.
An apparatus for controlling an electronic steering system, comprising:
- at least one sensor for acquiring sensing data for a driving state of a vehicle in motion;
- and
- a controller configured to estimate a rack force value based on the acquired sensing data in response to a cumulative driving distance of the vehicle being greater than or equal to a reference driving distance, to compare the estimated rack force value to learning data, and to output an alarm by checking whether a number of friction detections is greater than or equal to a critical number in response to the estimated rack force value being greater than the learning data.
