PCT No. PCT/SE81/00191 Sec. 371 Date Jan. 28, 1982 Sec. 102(e) Date Jan. 28, 1982 PCT Filed Jun. 29, 1981 PCT Pub. No. WO82/00122 PCT Pub. Date Jan. 21, 1982.In a system wherein a vehicle can be remotely controlled from any one of a plurality of control devices, each of which can emit operation command signals to the vehicle, each control device can also emit switching signals, each designating one of the other control devices and assigning control to the one designated. Each control device emits its signals in a mode unique to it, and the vehicle has a receiver for each control device, capable of receiving only signals from its control device, and a switching circuit connected with each receiver. Each switching circuit has an enabled and a disabled condition. When enabled, it carries operation signals from its receiver to actuating means whereby commands signified by operating signals are executed. Each switching circuit is enabled when it receives valid signals from its receiver and also receives an input from another switching circuit, produced in response to a switching signal assigning control to the control device corresponding to the thus-enabled switching circuit. An enabled switching circuit issues to all other switching circuits an output which disables them. |
