Assignee:

Hyster-Yale Group, Inc. - Fairview OR

International Classification:

B66F 17/00

B66F 9/075

Abstract:

A system includes a detection device configured to transmit and receive one or more signals in a generally vertical direction above a vehicle. Additionally, the system may include a processing device configured to measure a time of flight associated with the transmission and receipt of the one or more signals in the generally vertical direction. A distance travelled by the one or more signals may be determined based, at least in part, on the measured time of flight, and the distance travelled may be compared with a threshold distance to determine an overhead clearance of the vehicle. In response to determining the overhead clearance, a vehicle system may be activated.
