US 2025/0130040 A1 · APPARATUS AND METHOD FOR DETECTING ABNORMAL WHEEL ALIGNMENT

Abstract

Disclosed are an apparatus and method for detecting abnormal wheel alignment. The apparatus for detecting abnormal wheel alignment includes a sensor module and a processor operatively connected to the sensor module. The processor may calculate a steering angle error indicative of a difference between a target steering angle of a vehicle and a steering angle of the vehicle that has been detected based on lane information obtained by the sensor module, may calculate a rack force error indicative of a difference between a first rack force estimated based on information that has been fed back by a motor driven power steering system (MDPS) module of the vehicle and a second rack force estimated based on information including a yaw rate and lateral acceleration obtained by the sensor module, and may determine whether wheel alignment is abnormal based on at least one of the steering angle error and the rack force error.
