1. A proximity sensor system for a vehicle comprising:
- a zone detection module that switches a first remote sensor from a first mode corresponding to a near zone rearward of the vehicle to a second mode corresponding to a far zone rearward of the vehicle, wherein said near zone includes an area of coverage wider and shorter in range than an area of coverage of said far zone; and
a response module that responds to first objects in said near zone and that selectively responds to second objects in said far zone when said second objects are in motion.

Abstract
A proximity sensor system for a vehicle in reverse includes a zone detection module. The zone detection module switches a first remote sensor from a first mode corresponding to a near zone rearward of the vehicle to a second mode corresponding to a far zone rearward of the vehicle. The near zone includes an area of coverage wider and shorter in range than an area of coverage of the far zone. A response module responds to first objects in the near zone and selectively responds to second objects in the far zone when the second objects are in motion.

17. A proximity sensor system for a vehicle in reverse comprising:
-
a first remote sensor comprising a first near zone mode and a first far zone mode; a second remote sensor comprising a second near zone mode and a second far zone mode; a zone detection module that switches said first and second remote sensors from said first and second near zone modes to said first and second far zone modes as the vehicle moves in a rearward direction, wherein said first and second near zone modes cover areas rearward of the vehicle that have are wider and shorter in range than areas of coverage of said first and second far zone modes; an object tracking module that tracks position information for first objects in said first and second near zones and second objects in said first and second far zones; a response module that selectively responds to said second objects based on signals from said object tracking module indicating that said second objects are moving toward the vehicle and that does not respond to stationary second objects and that responds to all of said first objects; a visual alert device that activates based on response module signals; and an audible alert device that activates based on response module signals. - View Dependent Claims (18, 19)

20. A control method for a remote sensor system for a vehicle comprising:
-
moving the vehicle in a rearward direction; switching first and second remote sensors from near zone detection to far zone detection, wherein said near zone detection includes a wider field of view than said far zone detection and wherein said far zone detection detects areas more distant from the vehicle than said near zone detection; tracking position information for first objects based on said near zone detection; tracking position information for second objects based on said far zone detection; selectively responding to said second objects based on signals indicating that said second objects are moving toward the vehicle; responding to all of said first objects; generating a visual alert based on said first and second objects; and generating an audible alert based on said first and second objects.
