Abstract:
1. A method of parking angle determination and cross traffic alert for a host vehicle pulling into and backing out of a parking space, the method comprising the steps of: (a) detecting when the host vehicle is in a parking lot mode, the parking lot mode including the host vehicle traveling in a forward direction; (b) recording incremental vehicle angles traveled over corresponding incremental vehicle distances when the host vehicle is in the parking lot mode; (c) detecting when the host vehicle has parked; (d) calculating and storing a parking angle; (e) detecting when the host vehicle is backing out of the parking space after detecting the vehicle parked condition; (f) from a field of view of a first side sensor, determining a first side portion of interest where an object detected by the first side sensor will be considered for a cross traffic alert and a first side portion not of interest where an object detected by the first side sensor will not be considered for the cross traffic alert, with the sizes of the first side portion of interest and the first side portion not of interest being based on the calculated parking angle; and (g) activating the cross traffic alert when the vehicle is backing out of the parking space if an object is detected in the first side portion of interest.
