METHOD FOR DETERMINING MISALIGNMENT OF AN OBJECT SENSOR

摘要

A vehicle system and method that can determine object sensor misalignment while a host vehicle is being driven, and can do so within a single sensor cycle through the use of stationary and moving target objects and does not require multiple sensors with overlapping fields of view. In an exemplary embodiment where the host vehicle is traveling in a generally straight line, one or more object misalignment angle(s) αo between an object axis and a sensor axis are calculated and used to determine the actual sensor misalignment angle α.

1. A method for determining misalignment of an object sensor on a host vehicle, comprising the steps of:
determining if the host vehicle is traveling in a straight line; receiving object sensor readings from the object sensor, and obtaining object parameters from the object sensor readings for at least one object in the object sensor field of view; when the host vehicle is traveling in a straight line, using the object parameters to calculate an object misalignment angle αo between an object axis and a sensor axis for the at least one object; and using the object misalignment angle αo to determine a sensor misalignment angle α.
