Abstract
Operation of an industrial vehicle is controlled based on the location of that vehicle at a facility. The control method includes storing, in a memory device onboard the industrial vehicle, a definition of a first area in a facility. Radio signals are transmitted to the industrial vehicle from at least three transmitters, and for each radio signal, determining a propagation time from the transmitter to the industrial vehicle. A location of the industrial vehicle is derived from the propagation times of the radio signals, and the location is employed to determine when the industrial vehicle is within the first area. Operation of the industrial vehicle is altered in response to the industrial vehicle being within the first area. For example, the industrial vehicle may be disabled, its maximum travel speed limited or an alert is sent to the operator, when the industrial vehicle is within the first area.
