Abstract

An object detection system is configured to detect location of an object proximate a first surface of a vehicle. A beacon is configured to be positioned and repositioned relative to the vehicle. A controller is configured to process data from the object detection system and position data from the beacon. The controller is configured to define a first zone of interest relative to the first surface of the vehicle body structure without the beacon and further process object location data from the object detection system and output the object location data to the display relative to the first zone of interest. The controller determines current location of the beacon relative to the first surface of the vehicle body structure, defines a second zone of interest relative to the beacon and outputs the object location data to a display relative to the second zone of interest.

Claims

a controller configured to receive and process data from the object detector and position data from the beacon, and configured to determine whether or not the beacon is in the storage location,

the controller automatically determining that the beacon is in a deactivated mode in response to the beacon being located within the storage location, and

the controller automatically determining that the beacon is in an activated operation mode in response to the beacon being removed from the storage location and positioned relative to the vehicle body structure such that

in response to the beacon being in the deactivated mode, the controller is configured to define a first zone of interest relative to the first surface of the vehicle body structure and further process object location data from the object detection system and output an indication of the proximity of an object relative the first zone of interest, and

in response to the beacon being in the activated operation mode the controller determines current location of the beacon relative to the first surface of the vehicle body structure, defines a second zone of interest relative to the location of the beacon and outputs an indication of the proximity of an object relative to the second zone of interest.

2. The vehicle object monitoring system according to claim 1, wherein

the controller determines a calculated length of the vehicle body structure, with the first surface of the vehicle body structure defining one end of the calculated length when the beacon is in the deactivated mode, and
