Vehicle collision shield

摘要

In the present disclosure, systems and methods for preventing collisions between a ground services vehicle and other objects are described. In one embodiment, a system includes a digital three dimensional map of the outer dimensions of the ground vehicle, a micro radar device, a comparator, and an indicator. The micro radar device is secured to the ground vehicle. A comparator signals when an object is within a predetermined envelope around the outer dimensions of the ground vehicle. The comparator receives signals from the micro radar device, and includes dimension data from the three dimensional map. The indicator is responsive to the signal from the comparator. The indicator alerts of possible and pending collision when the predetermined envelope is breached. The indicator may also activate a brake mechanism to stop the ground vehicle. Methods for carrying out the invention by sensing a breach of the envelope and stopping the vehicle are also disclosed.

1. A system for preventing collisions between a ground vehicle and a stationary aircraft, the vehicle including movable elements that change the outer geometry of the vehicle, the system comprising:
a digital map of the three-dimensional outer dimensions of the ground vehicle, said map changing to describe any changes in the geometry of the vehicle; a proximity sensor secured to the ground vehicle; a comparator that signals when the aircraft is within a predetermined envelope around the outer dimensions of the ground vehicle, said comparator receiving signals from said proximity sensor and having dimension data from said digital map; and a brake mechanism activated by said comparator to automatically engage a ground vehicle brake when the predetermined envelope is breached.
